Application Area

The Lidar Module – an integral part of Sensor Simulation – allows for lidar sensor simulation based on the design principle of the sensor (laser and photodetector). The module provides physics-based simulation of lidar sensors with high variety of configuration options. The environmental simulation is based on raytracing technology. In addition, an API can be used to extend the functionality of the lidar simulation for data processing algorithms and to include custom sensor models. For each point of a point cloud, different values are calculated, e.g., surface normal vector, azimuth angle, elevation angle, distance, reflectivity, relative velocity, material ID and optical power. Additionally, the ray chronology of the scanning sensors can be simulated and is configurable. Multiple echoes (e.g., from the transmission of semi-transparent materials) are also considered.

Components and Characteristics

  • Real-time capable raytracing for the computation of the environmental model
  • Multiple echoes considered
  • Support for flash-based and scanning sensors
  • Basic sensor configuration via MotionDesk using a sensor specific GUI
    • Positioning and orientation of the sensor
    • Field of view
    • Sensor specific properties, e.g., configuration for azimuth, elevation, time, and timewise order of simulated rays
