METHOD AND COMPUTING DEVICE FOR SPECIFYING TRAFFIC LIGHT OF INTEREST IN AUTONOMOUS DRIVING SYSTEM

摘要

A method for specifying a target traffic light of an autonomous vehicle, the method comprising: (a) When the driving route of the autonomous vehicle is set in a state in which map data including absolute position information of a plurality of traffic lights is obtained, the computing device generates the absolute position information of the autonomous vehicle on the map data and the map data specifying a traffic light closest to the autonomous vehicle from among a plurality of traffic lights existing on the driving route as a target traffic light with reference to; (b) when a video image corresponding to the driving direction of the autonomous vehicle is input, the computing device is configured to refer to the absolute position information of the autonomous vehicle and the absolute position information of a traffic light of interest calculating relative position information of a target traffic light, and setting a region of interest (ROI) corresponding to the target traffic light on the video image with reference to the relative position information; and (c) detecting, by the computing device, the traffic light of interest located on the video image through image analysis with reference to the ROI, and recognizing the signal state of the traffic light of interest. computing device used.
