Event-based object recognition in the surroundings of a vehicle

摘要

Signal processing method for object recognition in the surroundings of a vehicle, comprising sending a coded pixel signal (202) comprising a plurality of pixels (224) of a current signal chirp from a first surroundings sensor (20) to a second surroundings sensor (22), the first surroundings sensor (20) being connected to a first vehicle (30) is mounted, wherein the second environment sensor (22) is mounted on a second vehicle (32); Receiving the coded pixel signal (202) in an image plane (222) of the second environment sensor (22); Extracting a sub-pixel signal from the current signal chirp, the pixel (224) of which has a change from a previously received signal chirp; and outputting the extracted sub-pixel signal for decoding; wherein the sub-pixel signal is extracted from pixels (224) within an area (226) of the image plane (222) in which the encoded pixel signal (202) is received as a collimated light beam.
