US Patent 10094916 LIDAR optics alignment systems and methods

One example method involves obtaining a plurality of images using a camera located at a given position relative to a light detection and ranging (LIDAR) device. A first image of the plurality may be obtained while a first aperture is interposed between the camera and the LIDAR device. A second image of the plurality may be obtained while a second aperture is interposed between the camera and the LIDAR device. The method also involves determining one or more alignment offsets between a transmitter of the LIDAR device and a receiver of the LIDAR device based on the plurality of images.
