The invention discloses a traffic signal lamp violation judgment method and system based on electromagnetic waves. The method comprises the following steps of: (10) collecting radiation information: collecting millimeter wave radiation data of vehicles passing through an intersection, and processing the millimeter wave radiation data to form high and low level signals; (20) judging whether the vehicles violate rules or not: judging whether the vehicles pass through an intersection or press lines when the signal lamp is red according to the high and low level signals and the state of the traffic signal lamp, and if the vehicles pass through the intersection when the signal lamp is red, judging that the vehicles violates rules; (30) shooting an optical image: shooting optical images of the vehicles if the vehicles violate rules, and not shooting optical images if the vehicles do not violate rules; and (40) identifying license plate numbers and giving an alarm: processing the vehicle optical images to obtain license plate number information of the violation vehicles and giving an alarm. The system comprises a detection end (1) and a monitoring end (2). The method and the system have the advantages of strong anti-interference capability, high accuracy and easy device installation.
本发明公开一种基于电磁波的交通信号灯违章判断方法与系统。方法包括如下步骤:(10)收集辐射信息:采集路口通过车辆的毫米波辐射数据,并进行处理,形成高低电平信号;(20)判断车辆是否违章:根据所述高低电平信号,并根据交通信号灯所处状态,判断车辆是否在信号灯为红灯时通过路口或压线,若车辆在信号灯为红灯时通过路口,则判定为车辆违章;(30)拍摄光学图像:若通过车辆违章,则拍摄得到车辆的光学图像,若车辆未违章,则不拍摄;(40)识别车牌号并报警:对所述车辆光学图像进行处理,得到违章车辆的车牌号信息并报警。系统包括探测端(1)与监控端(2),本发明的方法及系统,抗干扰能力强,准确度高,装置易安装。
