Abstract
A dynamic vision sensor (DVS) camera is described that directs scanning of a lidar. In one example, a DVS has an array of pixels, wherein each DVS pixel comprises a photodetector, and is configured to detect temporal contrast and generate an event in response. A lidar system has a light source configured to emit light, a scanner configured to direct the emitted light along a scan pattern contained within a field of regard of the lidar system, and a receiver configured to detect at least a portion of the emitted light scattered by one or more remote targets in a scene. A processor is coupled to the lidar system and to the dynamic vision sensor and receives the events, identifies a region of interest in the field of regard that corresponds to DVS pixels that generated the events, and adjusts a scan parameter of the lidar system in the region of interest.
