Abstract

In one embodiment, a facility for calibrating sensors of an autonomous vehicle (AV) includes a camera calibration target configured to be measured by and used for calibrating an optical camera of the AV; a light detection and ranging (LiDAR) calibration target configured to be measured by and used for calibrating a LiDAR transceiver of the AV; and a platform configured to allow the AV to drive onto and park on the platform. The camera calibration target and the LiDAR calibration target are positioned to be detectable by the optical camera and the LiDAR transceiver while the AV is parked on the platform. The platform is further configured to modify a lateral position, height, or orientation of the optical camera and the LiDAR transceiver relative to the camera calibration target and the LiDAR calibration target while the AV is parked on the platform.
