  • MULTI-SENSOR CALIBRATION SYSTEM
    Publication number: 20240095960
    Abstract: Techniques for performing multi-sensor calibration on a vehicle are described. A method includes obtaining, from each of at least two sensors located on a vehicle, sensor data item of a road comprising a lane marker, extracting, from each sensor data item, a location information of the lane marker, and calculating extrinsic parameters of the at least two sensors based on determining a difference between the location information of the lane marker from each sensor data item and a previously stored location information of the lane marker.

  • TIME SYNCHRONIZATION AND DATA ACQUISITION METHOD FOR GROUND TRUTH STATIC SCENE SPARSE FLOW GENERATION
    Publication number: 20180356824
    Abstract: A method of generating a ground truth dataset for motion planning is disclosed. The method incudes: collecting LiDAR scans; detecting two pose estimates that are closest to LiDAR scan accusation time; determining LiDAR's poses based on an interpolation; and transforming LiDAR raw scans into undistorted LiDAR scans.
