  • Publication number: 20230152464
    Abstract: Techniques for simulating LIDAR data are described. In one embodiment, a method for simulating LIDAR data may include retrieving a simulated scene that simulates a real-world scene, the simulated scene including at least one target object having a reflectivity r and located at a range R from a LIDAR sensor, the LIDAR sensor having at least one intrinsic parameter; generating a probability of detection (Pd) drop-off function for the LIDAR sensor, wherein the Pd drop-off function is related to r, R, and the at least one intrinsic parameter; for each data point comprising a ray emitted by the LIDAR sensor that hits the target object, generating a Pd value using the Pd drop-off function; and determining based on the Pd value whether to drop the data point.

  • Patent number: 10688841
    Abstract: A vehicle having a control system to utilize a movable suspension to increase sensor coverage. The control system can detect an object of interest that is partially, or completely, outside the field of view of one or more sensors on the vehicle. The system can then use the movable suspension to raise one portion of the vehicle and/or lower another portion of the vehicle to bring the object of interest at least partially into the field of view of the sensor, increasing the effective field of view of the sensor. When an object of interest is determined to be significant (e.g., a traffic or street sign), the system can attempt to bring the object of interest into view of the sensor by tilting the vehicle. The system can use different tilt rates and/or tilt angles depending on whether the vehicle is occupied or not.
