Sensor Simulation: Environment Perception for ADAS and AD
The detection of the environment builds the basis for assisted and automated driving (ADAS/AD). For the development and testing of driving functions, the vehicle and environment simulation DYNA4 offers models of lidar, camera, radar and ultrasonic sensors. Depending on the boundaries of your system under test, DYNA4 provides virtual sensor input on different levels, from physics-based raw sensor data to fused object lists. This enables, for example, the following use-cases:
- Testing object detection with virtually generated camera pictures or lidar point clouds
- Testing sensor fusion algorithms with object lists from multiple sensors such as radar and camera
- Testing ADAS/AD functions with a fused object list as an input
Sensor input on different levels from physics-based raw sensor data to fused object lists
