Intersection vehicle collision early warning evaluation method, device and system

Abstract

The invention provides an intersection vehicle collision early-warning evaluation method, device and system, and the method comprises the steps: obtaining continuous multi-frame early-warning equipment images of a to-be-evaluated vehicle, and carrying out the template matching of each early-warning equipment image based on a video early-warning template image, so as to determine the early-warning time of the early-warning equipment for transmitting video early warning; acquiring an evaluation vehicle position and an evaluation vehicle speed of the to-be-evaluated vehicle at the early warning time, and acquiring a target vehicle position and a target vehicle speed of the target vehicle at the early warning time; based on the evaluated vehicle position, the evaluated vehicle speed, the target vehicle position and the target vehicle speed, whether the to-be-evaluated vehicle and the target vehicle will collide is judged, and if yes, the first arrival time when the to-be-evaluated vehicle arrives at the predicted collision point is determined; and judging whether the video early warning sent by the to-be-evaluated vehicle is valid based on the early warning time and the first arrival time. According to the invention, the accuracy of early warning time determination is improved, and accurate evaluation of vehicle video early warning effectiveness is realized.

Description

technical field [0001] The present invention relates to the technical field of vehicle intelligent driving evaluation, in particular to a method, device and system for evaluation and evaluation of vehicle collision warning at intersections. Background technique [0002] Urban road intersections have always been considered to be areas with a high incidence of traffic accidents, and intersection collisions are one of the typical types of accidents. At present, corresponding specifications and requirements have been put forward for the intersection collision warning (Intersection CollisionWarning, ICW) function of vehicles at home and abroad. For example, the basic performance requirements of ICW are stipulated in the group standard T / CSAE 53-2020. There are many ways to implement ICW, including the vehicle collision warning algorithm of the intersection road spatio-temporal grid, the vehicle anti-collision warning method of the intersection based on V2X communication, etc. Wi...

Problems solved by technology

[0003] Vehicle early warning signals are mainly divided into two types: video early warning and audio early warning. The existing evaluation methods for vehicle video early warning and audio early warning mainly use manual judgment of early warning time after playback, and then evaluate whether the video early warning and audio early warning are effective. However, subjective errors that may be delayed or even ignored by manually judging the video warning signals sent out may lead to inaccurate evaluation results for the effectiveness of video warnings
