Towards a no driver scenario: autonomous and connected cars at the Computer Vision Center

20160601_111211~2

70% of the population is expected to live in cities by 2050, therefore intelligent mobility is now, more than ever, a pressing topic. Within this context, a project lead by CVC researchers Dr. Antonio López and Dr. David Vázquez, is accomplishing positive results within their platform, Elektra, where they develop research within the area of computer vision and deep learning to advance in autonomous driving in city scenarios.

As Dr. López explains, the European Commission considers autonomous driving as one of the top ten technologies that will drastically change citizen’s life. Not only will it reduce accidents but will help include citizens with low physical mobility, make transport more efficient and therefore lower our carbon /petrol dependence.

Elektra is born as an autonomous driving platform designed in the context of our project ACDC”, as stated by Dr. Antonio López. The ACDC project (Automatic and Collaborative Driving in the City) points its research in computer vision for ADAS towards a level 5 automation, (the scale being from 1 to 5, and 5 meaning no driver when driving in the city). A most challenging project indeed, only possible with a clear synergy of different research groups and enterprises.

Elektra is formed by more than 20 professionals from different backgrounds, all summing up to the project. Within the research groups we find the CVC ADAS (Automatic Driving Assistance Systems) group, the CAOS (Computer architecture & Operating Systems) group at the UAB (Universitat Autonoma de Barcelona); the Research Center of Supervision, Safety and Automatic Control at UPC (Universitat Politècnica de Catalunya); the CTTC (Telecommunications Technical Center of Catalonia) and the IEEC (Institute of Space Studies of Catalonia) as well as the UAB-DEIC-Senda (Department of Information and Communications Engineering – Security of Networks and Distributed Applications) research group and the UAB-CEPHIS (Center of Prototypes and solutions Hardware-Software) team. Within businesses, Elektra has the input of the know-how of CT Ingenieros, a Barcelona based company dedicated to innovation within engineering in different infrastructure sectors.

The project, with an electric prototype, is highly relying on computer vision techniques for perception (stereo, stixels, obstacle detection, scene understanding) which tend to be computationally demanding, localization (GPS + IMU and vision) and navigation (Control and Planning). With this, the group has arrived to their first milestone, which is to “move autonomously from a starting point to a final point in a comfortable way and controlling that the trajectory always corresponds to free-navigable space and without disturbing pedestrians”.

Cameras, being passive sensors, have been preferred for the AI community when regarding driving. “Images give us a high amount of information to drive”, as explained by Dr. López, “after all, this is how humans do it. We therefore, needed to give the car the ability to interpret the information around him”. That includes pedestrian (obstacle) detection, free navigable space detection, localization and route planning. “Of course, cameras aren’t as precise as a human eye. Autonomous driving can’t only be possible with the use of computer vision, but it is a great ally”, as clarified by Dr. López.

As Dr. Vázquez sees it: “In order to have a car that can drive you need several things. Firstly, accurate pedestrian (obstacle) detection, in which CVC is definitely pioneer. Secondly, free navigable space detection, which is no more than detecting the lane without obstacles or interferences. Thirdly, localization. The car needs to know where it is at and where it is going towards. Fourthly, planning. The car has to plan its way from point A to point B in the smoothest way possible and thus define a global trajectory. And last but not least, control: to execute the motion plan performing the necessary manoeuvres”.

But cameras aren’t the only way to grant the car with perceptive abilities. Other technology used is based in sensors such as Lidar and Radar, involving raw data which has a more direct interpretation and thus provides an accurate distance estimation in different environmental conditions. The problems here are costs, these sensors being highly expensive, especially when compared to cameras, and the poor resolution of the data as well as the lack of details when capturing the world’s appearance. Visual data is comparatively far much richer in complexity and detail, the challenge being not only to give cars the ability to see and interpret, but to be able to take decisions when faced with different circumstances.

Library Living Lab presenting RRI at the Smart City Expo, Barcelona 2016

The first living lab located within a Library was the only living lab present at the Smart city Expo 2016 with a high number of visitors interested in replicating the Library’s model of innovation and citizen participation

Sant Cugat’s town council presented key projects in their stand at this year’s Smart City Expo, and the Library Living Lab was certainly one of the featured initiatives. With more than 14.000 visitors and over 600 guest cities, this Living Lab had a prominent space in order to promote Responsible Research and Innovation processes with a bottom up approach.

The Library Living Lab is a space where new dynamics and protocols of citizen participation to innovation are defined, contextualized in the public library. Furthermore, this space at Sant Cugat is a laboratory of services of the regional libraries network who is interested in replicating the model to other libraries, as well as a real implementation of the quadruple-helix model.

The Library Living Lab was created by a consortium including the Computer Vision Centre, the Universitat Autònoma de Barcelona and the Sant Cugat Town Council, as well as the Provincial Council of Barcelona and the Association of Neighbours of Volpelleres. The initiative is also part of the European Network of Living Labs who also had an important presence at the Expo.

At the Smart City Expo, the Library Living Lab presented the activities that have taken place in the last year as well as the different prototypes and technologies that can be found within this space, featuring the 3D club, technology of augmented reality applied to books and revalorization of digitised cultural works. Within the last year, more than 1000 citizens have participated in the Living Lab’s activities, with more than 35 media mentions and 43 scheduled activities.

The Smart City Expo was the perfect place to present this project, as it is completely aligned with the European Commission’s priorities and the H2020 philosophy, granting access to new technologies to citizens and thus contributing actively in creating veritable Smart Cities.
