Accurate reflection of reality – ground truth
The objective comparison of sensor signals with an absolute environmental reference (ground truth data) shows how accurately a sensor system captures its environment - and at the same time enables cost-effective development and validation of sensor technology at all levels of the development process. Certification authorities also need to be able to independently evaluate sensor systems for road approval of future autonomous driving vehicles. A high-precision sensor reference system is the basic prerequisite for this.
The future standard
The AVL Dynamic Ground Truth System (DGT) captures an exact 360° field of view of the vehicle environment for statistical comparison and validation of the ADAS/AD system under test (SUT). The captured image is composed of time-synchronized lidar, camera, and high-accuracy GNSS data to enable precise comparison of the DGT and SUT systems.
Using our powerful Perception software, the independent reference image of the vehicle environment is generated based on the recorded raw data. The result is an OSI data stream containing information about recorded objects such as cars, pedestrians, motorcycles, and traffic signs. These are used for analysis and validation against the SUT - taking us one step further towards Data Driven Development.
