WIPO Patent Application WO/2020/098297

A1

A method and a system for measuring the distance to a leading vehicle. The method for measuring the distance to a leading vehicle comprises: acquiring an RGB image and a depth image at a front viewing angle of a vehicle (S101); setting a target area frame in the RGB image (S102); extracting size data corresponding to a plurality of vehicles in the RGB image (S103); for each of the plurality of vehicles, according to the size data of the vehicle, determining a constraint frame of the vehicle in the RGB image (S104), calculating an overlapping ratio of the constraint frame of the vehicle to the target area frame (S105), calculating a normalized distance between the vehicle and the target area frame on the basis of the size data of the vehicle, the position of the constraint frame of the vehicle in the RGB image, and the position of the target area frame in the RGB image (S106); and according to the overlapping ratio and normalized distance corresponding to each of the plurality of vehicles, determining a target leading vehicle from the plurality of vehicles, and obtaining a vehicle distance between the target leading vehicle and the vehicle according to the depth image (S107).
