LiDAR and ambience signal fusion in lidar receiver

Abstract

Embodiments of the disclosure provide a receiver of an optical sensing system, and an optical sensing method. The receiver includes a micro shutter array configured to sequentially receive a series of laser beams returned from an environment at a plurality of time points. The micro shutter array sequentially opens a portion of the micro shutter array at a specified location at each time point, to allow a respective laser beam to pass through the micro shutter array at that time point and to reflect the ambient light by a remaining portion of the micro shutter array at that time point. The receiver further includes a photodetector configured to detect the laser beam that passes through the micro shutter array at each time point to obtain point cloud data and an image sensor configured to receive the ambient light reflected by the remaining portion of the micro shutter array to obtain image data. The receiver also includes a controller configured to fuse the point cloud data obtained from the photodetector with the image data obtained from the image sensor.
