Intersection blind area early warning method and system based on dynamic image perception

Abstract

The invention discloses an intersection blind area early warning method and system based on dynamic image perception. The method comprises: acquiring original traffic point cloud data collected by a dynamic vision sensor; preprocessing the original traffic point cloud data; performing clustering analysis on the noise filtering traffic point cloud data; classifying the vehicle and pedestrian targets; tracking a vehicle target, extracting the motion state of the vehicle target, and the motion state of the vehicle target comprising the real-time speed and the distance between the vehicle target and the intersection; judging the collision danger level of the vehicle according to the motion state of the vehicle target and a collision danger level setting threshold value; and publishing the motion state of the vehicle target and the collision danger level of the vehicle to a driver. According to the invention, the problems of parking interference on the roadside, poor light and low permeability of the intelligent vehicle-mounted terminal device in the prior art are solved, and the early warning real-time performance and accuracy of the traffic condition of the blind area of the intersection are improved.

Description

technical field [0001] The invention relates to the technical field of road traffic monitoring and traffic safety, in particular to a method and system for early warning of blind spots at intersections based on dynamic image perception. Background technique [0002] With the rapid development of the national economy, the number of automobiles has increased year by year, and road traffic accidents continue to occur, causing serious losses to people's lives and property. According to incomplete statistics, the number of traffic accidents in my country is about 160,000 every year, among which, traffic accidents caused by blind spots of sight account for a large proportion. Especially, when the car is turning or entering a curve, the driver's field of vision will be partially blocked by the A-pillar of the vehicle, resulting in a visual blind spot. In addition, when the driver concentrates on driving the vehicle, the driver's field of vision will also be reduced, which makes th...
