Which actors will drive innovation remains to be seen – but how trust is handled will be crucial. ​</b></p><p>​<span style="background-color:initial">Initially, we will primarily experience a significantly stronger mobile broadband, and the capacity to connect a larger number of units. 5G will also be ten times more energy efficient compared to 4G. Then, the notorious 5G boost of the Internet of Things will likely follow, and the expected revolution of industry, smart cities, cloud-based augmented reality and much more. Many industries have already launched connected services, based on other communication standards such as Wi-Fi or 4G.</span></p> <p>“Which is good, a rapid development gives competitive advantage. We learn as we go, and with 5G comes the opportunity to scale up”, says Tommy Svensson, researcher in Communication Systems.</p> <p>He believes this is an important revolution and exemplifies with the automotive industry.</p> <p>“Important aspects of their operations will be cloud-based, such as product updates to vehicles via the network and collection of data on maintenance needs, and we will see new traffic safety features thanks to fast communication to and in-between vehicles”, says Tommy Svensson.</p> <p>“There are still areas of development for 5G, such as AI that could self-optimize the networks, energy distribution to sensors, or to improve coverage in challenging areas across the globe”, says Tommy Svensson.</p> <p>The scenarios for the future are attractive, but what does it take for new technology to bring innovation on a broad front? Erik Bohlin at the Department of Technology Management and Economics studies regulation and competition in telecom. He says there is an ongoing debate about which actors are likely to drive the development.</p> <p>“Mobile operators need to be on their toes if they want to drive innovation in the 5G cloud. It is very likely that there will be other actors. Cloud services of today are mostly driven by other than mobile operators”, says Erik Bohlin.</p> <p>“With 5G there is a possibility to use more frequency bands, different frequency bands may be suitable for different purposes. There is also a discussion about allocating a frequency range for specific applications. Several countries in Europe have already taking this decision, including Sweden”, says Erik Bohlin.</p> <p>Some mean that it would benefit innovation to open the market for new actors to drive and develop new applications. Erik Bohlin and his colleagues have studied the current policies for telecom and frequency allocation and compared with available research on innovation systems. The analysis shows that today's regulation of the telecom market in Europe has mainly been focused on competition issues, to avoid any individual player becoming too dominant.</p> <p>However, with the launch of 5G, the issue of promoting innovation has been raised. But there is no simple answer on how to set up a frequency allocation auction in order to promote innovation, according to Erik Bohlin. Innovation is difficult to predict. He makes a historical comparison.</p> <p>“Many believed that 3G was going to boost innovation, but it was not until smartphones came that we saw an upswing. Nor could anyone predict that today's major business areas would be based on free services on the Internet, such as Google, Facebook and Spotify.”</p> <p>Most of the debate about 5G the last year has concerned security. High security requirements will be imposed on both operators and suppliers of infrastructure. In February it was decided that the Swedish Post and Telecom Authority (PTS), who are hosting the frequency auctions, needs to consult with the Swedish Security Service (Säpo) and the Swedish National Defense before granting any frequency permits.</p> <p>5G also enables new kinds of cloud services, but trust will be crucial in order to successfully provide these services.</p> <p>“In order to trust the telecom operators with these services, they need to ensure security, confidentiality, integrity. Some industry actors mean that they need to run their own services”, says Tomas Olovsson at the Department of Computer Science and Engineering.</p> <p>“If you look at the 5G network itself, the security need not be more challenging than for 4G. It's just a matter of moving data from a to b. Security can be handled in the same way as today, at a higher level in the applications”, says Tomas Olovsson.</p> <p>In terms of security, there are also benefits with 5G.</p> <p>“With 5G there is an opportunity to put parts of the security in the network itself and for some applications it can be a big advantage”, says Tomas Olovsson.</p> <p>For example, letting the network help authenticate the party you are communicating with in time-critical situations, or using a targeted radio signal, making wiretapping more difficult.</p> <p><br /></p> <p><em>Text: Malin Ulfvarson</em></p> <p><em>Illustration: Yen Strandqvist</em></p> <p><br /></p> <p><a href="http://chalmeriana.lib.chalmers.se/chalmersmagasin/cm2020_1/index-h5.html?page=1#page=28">Republished from Chalmers magazine no. 1 2020</a> (In Swedish)</p> <p><br /></p> <p><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/CM/illustration5G_CM-nr1-20.jpg" alt="illustration of a connected city" style="margin:5px" /><br /><br /><br /></p> <p>Also read: <a href="/en/departments/e2/news/Pages/5G-enables-communicating-gadgets-and-sustainability.aspx">5G enables communicating gadgets and sustainability</a></p> <p>​<br /></p>Mon, 15 Jun 2020 13:00:00 +0200https://www.chalmers.se/en/departments/e2/news/Pages/10-million-grant-to-antenna-research.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/10-million-grant-to-antenna-research.aspx10 million grant to antenna research<p><b>​Marianna Ivashina receives a major grant from the Swedish Foundation for Strategic Research, to be used in a Swedish-Taiwanese collaborative research project to develop antenna technologies for the beyond-5G wireless communication applications, products, and services. ​</b></p>​<span style="background-color:initial">Professor Marianna Ivashina is leading the Antenna systems research group at the Department of Electrical Engineering at Chalmers University of Technology.

Or rather, have decided to merge several resources into a single point of contact for researchers in need of digital infrastructures – to manage and make available research data, large calculations and visualisation. With e-Commons, Chalmers is leading the way into the future.</b></p>​<span style="background-color:initial">New digital tools are revolutionising research – a development we have only seen the beginning of. Universities that succeed in exploiting and developing these opportunities effectively will have a competitive advantage. It concerns the needs of storage, handling and analysis of large amounts of data and large-scale simulations. In addition, increasing requirements for available and reusable data from publicly funded research.</span><div><br /></div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/eCommons/LarsBorjesson.jpg" class="chalmersPosition-FloatRight" alt="Lars Börjesson" style="margin:5px" />“Today, the infrastructure is divided on different functions, which means that researchers in need of simulations go to a supercomputer centre and do their thing there, then to another infrastructure to do their visualisation, and yet another source for storage, archiving and making data available. It’s very time-consuming and obstacles arise along the way”, says Lars Börjesson, the President’s advisor for national and international research infrastructure.</div> <div><br /></div> <div>“When we merge the resources, our researchers can get full-service assistance with their projects. They get the right expert from start to finish, which makes it much easier. We can simply introduce the digital tools much faster in all research areas.”</div> <div><br /></div> <div>Chalmers is not alone in having its e-infrastructure spread across several functions. This is the case at most universities.</div> <div><br /></div> <div>“From what we can see, no other university in Europe has taken the step to build a merged e-infrastructure. But the need exists, both nationally and internationally – and it is on top of the agenda. But it takes time to introduce.”</div> <div><br /></div> <div>As Chalmers representative in national and European bodies, Lars Börjesson has insights into the agendas. Many of the ideas behind Chalmers e-Commons are drawn from discussions at national and European level. One such body is the e-Infrastructure Reflection Group (e-IRG), which for several years was led by a Swedish researcher – Sverker Holmgren.</div> <div><br /></div> <div><strong>An outstanding recruitment</strong></div> <div>Sverker Holmgren is professor in scientific computing and newly recruited director of Chalmers e-Commons. In addition to his chairmanship of the e-IRG, he has also been the director of the national e-infrastructure SNIC, worked at Nordforsk with responsibility for the Nordic cooperation in e-science and participated in governmental infrastructure investigations. It sounds like an outstanding recruitment, and it's mutual. Sverker Holmgren has worked visionally with the issues of e-infrastructure for many years, but now it is time for action.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/eCommons/SverkerHolmgren_FotoTerjeHeiestad.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“Chalmers strength lies in the extensive preparatory work, a process that is well anchored in the faculty, and with a rector's decision, where the structure is well defined and elaborated. I do not think that any other university has come this far, neither in Sweden nor internationally. So, the conditions are good, but that does not mean that the work will be easy, says Sverker Holmgren with a smile.</div> <div><br /></div> <div>The main challenges are not in technology, or in building infrastructure. It is about bringing together several different resources and operations, with rather different formats and backgrounds, so that they work together in the best way to build this integrated horizontal structure focused towards the research needs.</div> <div><br /></div> <div>“Almost all research areas have either realized or are about to realize – they need a range of e-infrastructure resources, the entire chain. This is where e-Commons is needed, as a researcher you shouldn’t have to turn to five different services, which today also applies different formats and languages.”</div> <div><br /></div> <div><strong>Many initiatives underway</strong></div> <div>Similar plans are underway in this direction at both national and European levels. The planning of a European e-infrastructure Commons started during Sverker Holmgren's leadership of e-IRG, and in addition, the European Commission has been pushing the discussions on sharing of research resources and open science, and the digital platform that is required to enable the vision. This has resulted in the European Open Science Cloud (EOSC) initiative, on which the EU places considerable resources.</div> <div><br /></div> <div>At the national level, there are forces driving a merger of the national e-infrastructures: SNIC, Sunet, Swedish National Data Service (SND), and sensitive register data. In early May, the government announced an assignment to Tobias Krantz, to investigate and submit proposals for implementation.</div> <div><br /></div> <div>“Our aim with e-Commons is completely in line with national and European plans. We are well positioned at Chalmers, we already have the mindset and have started to implement it”, says Lars Börjesson.</div> <div><br /></div> <div><em>Text: Malin Ulfvarson</em></div> <em> </em><div><em>Photo: (C3SE) Anna-Lena Lundqvist, (Lars Börjesson) Jan-Olof Yxell, (Sverker Holmgren) Terje Heiestad.</em></div> <em> </em><div><br /></div> <div><br /></div> <div><strong>Included in Chalmers e-infrastructure Commons:</strong></div> <div><ul><li>C3SE, Chalmers Centre for Computational Science and Engineering.</li> <li>e-science centre, user support</li> <li>Representatives from the Library/Department of Communication and Learning in Science, the operational support of IT and archive, and links to these divisions</li> <li>Data Science Research Engineers</li> <li>SNIC's national AI/ML resource</li> <li>Visualization Expertise, InfraVis, Visual Arena</li> <li>Connections to Chalmers AI Research Centre (CHAIR) and Data factory at Lindholmen</li></ul></div> <div><br /></div> <div><br /></div> <div><strong>Short bio, Sverker Holmgren</strong></div> <div>Professor of scientific computing at Uppsala University, where formerly the director of the strategic research initiative eSSENCE and project manager for the university's research data project.

But the technology will also enable less waste of resources and induce a development towards a more sustainable society.​</b></p>​<span style="background-color:initial">What differs 5G from the previous generations of mobile standards is that the communication largely is controlled by software, and that the ‘cloud’ is moved closer to the users and applications.</span><div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/5G%20möjliggör%20kommunicerande%20prylar%20och%20hållbarhet/Tommy_Svensson_2016_150x200px.jpg" class="chalmersPosition-FloatRight" alt="Tommy Svensson" style="margin:5px;width:170px;height:228px" />“5G is an enabler for digitalisation and more efficient processes”, says Tommy Svensson, Professor of communication systems, focusing his research on wireless communications. “This means that machines can exchange information with each other, and that many devices are connected at the same time. Sensors are collecting large amounts of data of various kinds, which are processed rapidly for tailor-made and intelligent applications.”</div> <div><br /></div> <div>“Sometimes, I call myself a digital navvy; I'm building wireless digital roads. My research deals with the infrastructure and how data traffic can travel wirelessly, quickly and without obstacles. At the Department of Electrical Engineering at Chalmers University of Technology we are successful in our research on mobile systems, in my area with the focus on radio traffic to and from base stations in the mobile network, as well as in research on mobile base stations and vehicle communications.”</div> <div><br /></div> <div><strong>Fast, robust and powerful</strong></div> <div>5G consists of more advanced technical solutions than 4G and therefore enables the technology to be used for many more purposes. The researchers regard 5G as a tool for solving major societal challenges: climate impact, scarce natural resources, food production, care for an aging population, safe working environments, etc.</div> <div><br /></div> <div>“This new technology not only enables ‘Internet of information’ but also ‘Internet of skills’. That means that the exchange of information, as well as skills and abilities, can be performed from a distance,” Tommy Svensson continues. “For example, the possibility of remotely controlling machines in a mine from a safe and comfortable office above ground. Or surgery that can be performed from a distance and thus enabling more patients to benefit from the expertise of specialist doctors.”</div> <div><br /></div> <div>In order to perform this kind of advanced tasks correctly and safely from a distance, the communication system must be robust and allow very quick data transports. 5G may reduce delays in the data transmission to as short as 1 millisecond. The network can then also be virtually divided into software-controlled slices, where different slices can be designed and dynamically created for individual tasks. In that way the performance is ensured.</div> <div><br /></div> <div>Augmented reality is a concept that is often mentioned in the context of 5G. It means combining reality with digital content, via a mobile phone or through special glasses, that allows for the surroundings to be experienced with computer generated images placed on top. The faster the data transfer is, the more applications are available.</div> <div><br /></div> <div><strong>Paves the way for greater sustainability</strong></div> <div>“In my opinion, 5G clearly enables a transfer from a ‘wear and tear’ mentality to a society that is based on a higher degree of sustainability”, says Tommy Svensson. “Partly it is about the technology itself, and partly about what can be achieved by using the technology.”</div> <div><br /></div> <div>The 5G technology saves energy by streamlining the control of radio signals and by transferring only what is really needed – no superfluous system information needs to be handled. This makes the connection ten times more energy efficient than 4G of today.</div> <div><br /></div> <div>Through various applications of 5G, processes can be made more efficient and consume less resources. This means that it will be possible to benefit from individual and condition-based solutions, provided by multi-connected machines that are able to exchange information with each other.</div> <div><br /></div> <div><strong>Many applications</strong></div> <div>“In smart cities, public transports and other means of transportation can be adapted to external circumstances and to people's intentions”, Tommy Svensson exemplifies. “This makes the traffic flow smoother and less energy-consuming in total. The same applies to water consumption, waste management and other community services. Self-driving cars may not have their breakthrough as fast as originally anticipated, but by using mobile technology it is evident that they eventually will be an important component of the smart transport system of the future.”</div> <div><br /></div> <div>In agriculture, it will be possible to individually regulate watering and fertilization according to the needs of each plant through connected farm machinery and systems for data analysis. Another example is industrial production systems that can be made more flexible and thus enabling faster adjustments of the production to new conditions. If the machine park is equipped with connected sensors, maintenance measures can be adapted to the actual need without causing unplanned downtime.</div> <div><br /></div> <div>“In the future, the driving force for manufacturing companies will be more focused on creating offers that are sustainable, since it will be the services provided rather than the products themselves that the customers want to pay for,” says Tommy Svensson. “This development is being promoted in the connected 5G community.”</div> <div><br /></div> <div>E-health; using digital tools and exchanging information digitally to achieve and maintain good health, is an area also of great interest related to the 5G technology.

Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded multiple scientific articles, in publications including Nature Communications.</b></p>​<span style="background-color:initial">Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now. But to accommodate this digital lifestyle, a huge amount of data needs to be transmitted through fibre optic cables – and that amount is increasing at an almost unimaginable rate, consuming an enormous amount of electricity. This is completely unsustainable – at the current rate of increase, if no energy efficiency gains were made, within ten years the internet alone would consume more electricity than is currently generated worldwide. The electricity production cannot be increased at the same rate without massively increasing the usage of fossil fuels for electricity generation, which of course would lead to a significant increase in carbon dioxide emissions.</span><div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smarta%20datachips%20del%20av%20lösningen%20för%20att%20göra%20internet%20energisnålare/Peter-Andrekson_250x333px.jpg" class="chalmersPosition-FloatRight" alt="Peter Andrekson" style="margin:5px;width:200px;height:263px" /><br /><span style="background-color:initial">“The challenge lies in meeting that inevitable demand for capacity and performance, while keeping costs at a reasonable level and minimising the environmental impacts,” says Peter Andrekson, Professor of Photonics at the Department of Microtechnology and Nanoscience at Chalmers.</span><br /></div> <div><br /></div> <div>Peter Andrekson was the leader of the 5-year research project <a href="https://research.chalmers.se/en/project/?id=5914" target="_blank">‘Energy-efficient optical fibre communication’</a>, which has contributed significant advances to the field.</div> <div><br /></div> <div>In the early phase of the project, the Chalmers researchers identified the biggest energy drains in today's fibre optic systems. With this knowledge, they then designed and built a concept for a system for data transmission which consumes as little energy as possible. Optimising the components of the system against each other results in significant energy savings.</div> <div><br /></div> <div>Currently, some of the most energy-intensive components are error-correction data chips, which are used in optical systems to compensate for noise and interference. The Chalmers researchers have now succeeded in designing these chips with optimised circuits.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smarta%20datachips%20del%20av%20lösningen%20för%20att%20göra%20internet%20energisnålare/Per-Larsson-Edefors_250x333px.jpg" class="chalmersPosition-FloatLeft" alt="Per Larsson-Edefors" style="margin:5px;width:200px;height:263px" />“Our measurements show that the energy consumption of our refined chips is around 10 times less than conventional error-correcting chips,” says Per Larsson-Edefors, Professor in Computer Engineering at the Department of Computer Science and Engineering at Chalmers.</div> <div><br /></div> <div>At a systemic level, the researchers also demonstrated the advantages of using ‘optical frequency combs’ instead of having separate laser transmitters for each frequency channel. An optical frequency comb emits light at all wavelengths simultaneously, making the transmitter very frequency-stable. This makes reception of the signals much easier – and thus more energy efficient.</div> <div><br /></div> <div>Energy savings can also be made through controlling fibre optic communications at the network level. By mathematically modelling the energy consumption in different network resources, data traffic can be controlled and directed so that the resources are utilised optimally. This is especially valuable if traffic varies over time, as is the case in most networks. For this, the researchers developed an optimisation algorithm which can reduce network energy consumption by up to 70%.</div> <div><br /></div> <div>The recipe for these successes has been the broad approach of the project, with scientists from three different research areas collaborating to find the most energy-saving overall solution possible, without sacrificing system performance.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smarta%20datachips%20del%20av%20lösningen%20för%20att%20göra%20internet%20energisnålare/Erik-Agrell_250x333px.jpg" class="chalmersPosition-FloatRight" alt="Erik Agrell" style="margin:5px;width:200px;height:263px" />These research breakthroughs offer great potential for making the internet of the future considerably more energy-efficient.

The GATE Institute is located in Sofia and is a partnership between Sofia University, Chalmers University of Technology and Chalmers Industrial Technologies.</b></p><p>​<br />The initiative is made through funding for seven years from the EU's Horizon 2020 Widespread programme, which aims to promote competence and innovation across Europe and thereby strengthen European competitiveness and ability to meet societal challenges. The goal is to build research capacity and promote innovation power.<br /><br />Graham Kemp at the Department of Computer Science and Engineering at Chalmers has been working with preparations and the application since 2017 and is very pleased that the Institute has now been launched.<br /><br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/GATE/Gate_GrahamKemp.jpg" alt="Graham Kemp" class="chalmersPosition-FloatRight" style="margin:5px;vertical-align:middle;width:200px;height:288px" />“We see an opportunity to share knowledge and experience in a field that is developing extremely rapidly. Our participation in GATE will lead to greater international impact, perspectives and interaction. In the longer term the GATE Institute will become a strong partner for collaboration in Eastern Europe”, says Graham Kemp.<br /><br />The research is focused on four strategic application themes: future cities, intelligent government, smart industry and digital health. GATE will employ over 100 researchers and install three new research labs at Sofia University, City Living Lab, Digital Twin Lab, in multidisciplinary collaboration with industry, as well as Virtual Reality and Big Data Visualisation (Open Visualisation Lab).<br /><br />The GATE Institute, as the only Big Data centre of excellence in Eastern Europe, will form a hub in a European network of more than 50 Big Data centres. GATE thus plays a strategically important role in expanding the network and contributing to knowledge transfer and innovation that will provide exchange not only at national or regional level, but for the whole of Europe. GATE will gather and unite everyone with interest in the research field – academia, government, industry and society.<br /><br />To the webpage of Gate: <a href="http://www.gate-coe.eu/" target="_blank">www.gate-coe.eu <br /></a></p> <p><em>This project has received funding from the European Union’s Horizon 2020 WIDESPEAD-2018-2020 TEAMING Phase 2 programme under Grant Agreement No. 857155.</em></p> <p><br />Captions</p> <p><strong>Group photo:</strong> Participants at the GATE kick-off meeting on 7th October 2019, in Sofia, Bulgaria.

The question is relevant not only to humans but also to self-driving cars that must be confident about their own position. Researchers at Chalmers University of Technology are developing smart algorithms for so-called visual localisation based on machine learning of large amounts of data collected from photos.</b></p>​<img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smart%20bildteknik%20bygger%20artificiellt%20lokalsinne/FredrikKahl_250x300px.jpg" class="chalmersPosition-FloatRight" alt="Fredrik Kahl" style="margin:5px" /><span style="background-color:initial">“Visual localisation means that a robot or car should be able to determine its current position using camera images that are compared to a map of the surroundings”, says Fredrik Kahl, professor of computer vision and image analysis at the department of Electrical Engineering at Chalmers. &quot;It is about identifying distinct features and comparing them to already known characteristics in the surroundings, which are positioned on a three-dimensional map.&quot;</span><div><br /><span style="background-color:initial"></span><div>Of the methods currently available to determine your position, camera is the most promising in this context.</div> <div><br /></div> <div>”Camera technology is comparatively cheap and provides access to a lot of information”, Fredrik Kahl continues. “There are several possible applications for the technology, where self-driving cars and unmanned vehicles probably are the most prevalent. Research is also underway in areas such as smart camera technology used in mobile phone navigation apps, in industrial production processes and in flexible systems for inspection of various environments.”</div> <div><br /></div> <div>One example, where the technology is now being demonstrated in a supermarket setting for later transfer to other applications, is the research project ‘Semantic Mapping and Visual Navigation for Smart Robots’, funded by the Swedish Foundation for Strategic Research. The project is headed by Fredrik Kahl and involves researchers from Chalmers and Lund University among others.</div> <div><br /></div> <div>”Semantic mapping means training the system to be able to recognise named physical objects in pictures and link them to a geographical position”, Fredrik Kahl says. “In the supermarket setting, the system first gets to learn how selected products look like and what they are called, and then it should be able to register where these products are located on the shelves in the store. To fulfill the task, various subsystems in machine learning, computer vision and robotics need to work together.”</div> <div><br /></div> <div>This technology will be tested in a supermarket in Stockholm, where a drone will fly along the shelves to identify which and how many products of each kind that are in stock. One challenge is that the products on the shelves can block each other.</div> <div><br /></div> <div>There are significantly more difficulties to overcome when transferring this technology outdoors and incorporating it into a self-driving car. Then, factors such as weather, daylight and time of the year also need to be considered.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smart%20bildteknik%20bygger%20artificiellt%20lokalsinne/kamerabilder_750px.jpg" class="chalmersPosition-FloatLeft" alt="camera images" style="margin:5px" /><br /><br /><br /></div> <div><br /></div> <div>“A picture taken on a beautiful summer day differs quite a lot from a picture taken at the same place on a wintry evening in January”, says Fredrik Kahl. “Without leaves on bushes and trees, the view can be completely changed, and other objects appear in the picture instead. Fog, snow and rain, in turn, are blurring the recognition marks.”</div> <div><br /></div> <div>Therefore, in order to build the visual localisation system, you need to have access to many photos taken under different exterior circumstances from the same geographical location.</div> <div><br /></div> <div>The researchers are putting labels, annotations, for various types of phenomena on the images that they want the system to recognise, such as ‘road’, ‘pavement’, ‘building’ etc. Often, subdivisions are needed for the annotations to be useful, for example ‘vegetation’ becomes a too comprehensive label. Annotations are needed, but the work is time-consuming, and it is therefore important to find a balanced level for the number of classifications. </div> <div><br /></div> <div>Machine learning in artificial neural networks is used to train the system, bit by bit improving the ability of the self-driving car or robot to recognise the surroundings and to orient itself.</div> <div><br /></div> <div>”As our algorithms become more accurate and the three-dimensional map is being built up, fewer images will be needed for the system to be able to locate itself”, Fredrik Kahl says. “A lot of tricky problems still remain to be solved, but that is what makes this field so exciting and fun to work with.”</div> <div><br /></div> <div><strong>Website to test the accuracy of the localisation</strong></div> <div>The Chalmers researchers have launched a website, that up till now contains more than 100 000 collected images.
