A foggy weather red light running vehicle evidence collection system based on radar and vision fusion

Abstract

This invention relates to the field of traffic control technology, and more particularly to a system for detecting red-light violations in foggy weather based on radar-visual fusion. The system includes: a fog perception module, a mode switching module, a behavior detection module, an effectiveness determination module, a dynamic control module, and a vehicle evidence collection module. The fog perception module collects fog characteristic parameters and analyzes the fog characteristic values. The mode switching module determines the operating mode of the radar-visual fusion device. The behavior detection module collects spatiotemporal behavior characteristic parameters of the radar-visual fusion device and analyzes the spatiotemporal behavior characteristic values. The effectiveness determination module determines whether the effectiveness of the radar-visual fusion device meets the standard. In response to the radar-visual fusion device's failure to meet the standard, the dynamic control module determines the adjustment range of the fog characteristic threshold. In response to the radar-visual fusion device's compliance with the standard, the vehicle evidence collection module collects evidence from the target vehicle that has violated the red light. This invention improves the accuracy of red-light violation detection and evidence collection in foggy weather.
