US Patent 11609329 Camera-gated lidar system

A machine vision system comprises a camera configured to generate one or more images of a field of regard of the camera, a lidar system, and a processor. The lidar system includes a laser configured to emit light, where the emitted light is directed toward a region within the field of regard of the camera and a receiver configured to detect light returned from the emitted light. The processor is configured to receive an indication of a location based on the returned light and determine, based on the one or more images generated by the camera, whether the indication of the location is associated with a spurious return.
