Abstract: A method of calibrating a LiDAR system includes providing a calibration target with an IR source. A partially IR opaque mask is proximate to the source and defines a plurality of regions with known areas that are at least partially transparent to IR. A vehicle coordinate system is then determined. The calibration target is then positioned in the vehicle coordinate system in a predetermined position with a predetermined orientation. An image of the calibration target is acquired with the LIDAR sensors. Image processing is performed to determine the position and orientation of the calibration target in the LiDAR sensors coordinate system. A rotation of the LIDAR sensors around an axis of attachment of the LiDAR sensor is determined from the image processing that compensates for misalignment of the LIDAR sensors. The LIDAR sensor coordinate system is then adjusted to match the vehicle coordinate system based on the determined rotation.
