Radar-triggering-based system and method for automatically recording red light running

Abstract

The invention provides a radar-triggering-based system for automatically recording red light running. The system comprises a radar and an intelligent snapshot unit and is characterized in that the 3D radar can acquire speeds and outlines of multiple targets, and the intelligent snapshot unit judges whether a vehicle breaks a traffic law according to the speeds and coordinate data sent by the radar. A detecting method of the radar-triggering-based system comprises the steps: (a) mounting a device; (b) establishing a traffic marking; (c) setting a coordinate value output by the radar; (d) judging whether the vehicles are overspeed; (e) calculating the outlines of the vehicles; (f) judging whether the vehicles press a line; (g) determining the types of the vehicles; taking a picture to obtain evidences. The radar-triggering-based system for automatically recording red light running and the detecting method can analyze the speeds and the moving tracks of the outlines of the vehicles and effectively identify if the vehicles break the traffic law. Compared with coil detecting and video detecting, the radar-triggering-based system has higher adaptability to severe weather conditions, detecting efficiency is higher, the omission rate is lower, and the radar-triggering-based system is suitable for application and popularization.

Description

technical field [0001] The present invention relates to a radar-triggered automatic recording system and method for running a red light, and more specifically, to a radar-triggered automatic recording system and method for running a red light that can detect speed and track the trajectory of a vehicle profile. Background technique [0002] In the existing automatic recording system for running a red light in road traffic, the main detection methods are coil detection and video detection. Among them, the coil detection is to cut the coil on the road, and then sense the vehicle through the vehicle detection equipment connected to the coil, thereby triggering the camera to capture the vehicle. However, the problem with coil detection is that the construction is more complicated, and the road needs to be cut, and then the coil is easy to break, resulting in a relatively large amount of maintenance. [0003] Video detection is to detect vehicles through the video of the camera, ...
