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

摘要

In a method for specifying a traffic light of interest for an autonomous vehicle, (a) When map data including absolute location information of a plurality of traffic lights is acquired and a driving route of the autonomous vehicle is set, the computing device provides the absolute location information of the autonomous vehicle and the map data on the map data. Specifying a traffic light closest to the autonomous vehicle among a plurality of traffic lights existing on the driving route as a traffic light of interest; (b) When a video image corresponding to the driving direction of the autonomous vehicle is input, the computing device refers to the absolute location information of the autonomous vehicle and the absolute location information of a traffic light of interest, and the interest from the autonomous vehicle 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 positioned 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.
