Abstract: A system for determining pose of a lidar sensor in an environment in order to calibrate the lidar sensor. The system includes at least two calibration boards, each having a first edge and a second edge. There is a controller coupled to the lidar sensor to cause the lidar sensor to direct a lidar scan at the calibration boards.
