Problems solved by technology

[0005] This technical solution requires the installation of multiple millimeter-wave radar sensing units on each passenger vehicle, and the mandatory installation of radar on each vehicle is not only costly, but also difficult to actually deploy in each vehicle, so the current implementation effect is not ideal

Abstract

The invention provides a millimeter wave-based traffic side intersection moving target identification early warning method and system. The method comprises steps of carrying out object detection on electromagnetic waves emitted by a traffic main road through a main road radar assembly, and extracting coordinates and speed information of a main road moving target in the installation direction of the main road radar assembly from data returned to the main road radar assembly; when the speed of the main road moving target approaching the main road radar assembly is greater than a preset early warning speed threshold, performing acousto-optic display early warning on the information of the main road moving target on a traffic branch; carrying out object detection on electromagnetic waves emitted by a traffic branch through a branch radar assembly, and extracting coordinate and speed information of a branch moving target in the installation direction of the branch radar assembly from data returned to the branch radar assembly; and when the speed of the branch moving target approaching the branch radar assembly is greater than a preset early warning speed threshold, performing acousto-optic display early warning on the branch moving target information on the main traffic road. The method is convenient to deploy, can early warn the moving target at the traffic intersection in real time, and reduces traffic accidents at the intersection.

Description

technical field [0001] The invention relates to the technical field of road information processing, in particular to a millimeter wave-based method and system for identifying and warning moving targets at traffic-side intersections. Background technique [0002] Radar uses radio to find targets and determine their spatial positions. Therefore, radar is also called "radiolocation". Radar is an electronic device that uses electromagnetic waves to detect targets. The radar emits electromagnetic waves to irradiate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, and height. [0003] At present, at main and auxiliary intersections or triangular intersections, since the main intersection usually does not know the movement of auxiliary intersections, accidents are prone to occur, and a large number of traffic accidents occur at traffi...
