Abstract
A receiving system for a lidar, comprises: a receiving lens, configured to receive echoes of a detection laser beam reflected by an object from an exterior of the lidar; a reflective structure, disposed downstream of an optical path of the receiving lens, to receive the echoes from the receiving lens, and change a propagation direction of the echoes by reflection; a detector, disposed downstream of an optical path of the reflective structure to receive a reflected echo from the reflective structure; and a ghost line reduction device, disposed between the reflective structure and the detector, wherein the ghost line reduction device includes a physical structure to block an echo that causes a ghost line in a point cloud of the lidar from entering the detector. The receiving system resolves the misrecognition problem caused by ghost lines in the point cloud to improve the detection accuracy of the lidar.
