CONVICTION

Important results from the project

Projektet CONVICTION is built on three things: radar, lidar and surrogate target. The work with logging, simulation and data analysis has been done with a focus on these three items. Tools for handling log data for analysis have been programmed. Analysis tools have been refined. Sensor data from real objective and soft surrogate targets have been collected and analyzed. Simulation models have been improved. Radar HIL has been connected with scenario-based simulation. The effect of water on lidar has been studied theoretically and in simulation.

Expected long term effects

The background is that system´s perception of the outside world must have sufficient perceptiveness to, in the long run, enable a guarantee that the vehicle drives sufficiently responsibly. Test track measurements have found some differences, which are relevant to communicate with manufacturers, between surrogate targets and corresponding objects. Some variations of items have had less difference than expected. Verification between a scenario logged on a test track, scenario simulation and over-the-air radar HIL has been successful and points to increased future use.

Approach and implementation

The project has used platforms with three different ToF lidar and a triple with equal FMCW radar for logging point clouds and sampled antenna data. The platforms have provided linear and circular movement towards and around objects. The two biggest difficulties overcome have been synchronizing the radars which were based on development boards and ensuring that sensors are aligned. The influence of disturbances from water on lidar has been studied by simulation and analysis. Logging from the test track has been compared with scenario-based simulation and with over-the-air radar.
