摘　　要：随着道路交通管理需求的发展,道路交通技术监控系统日益成为缓解交通安全管理部门压力、保证道路交通安全畅通的重要组成部分。其合理使用有效规范了车辆的行驶。在道路交通技术监控系统中,车辆违法行为的记录和取证尤为重要,然而在取证图片中红灯灯色和实际人眼辨识结果存在差异。因此,结合道路交通技术监控系统的应用需求,本文针对摄像机光线传输原理及信号灯光学特性进行原因分析,提出还原信号灯灯色的方法。With the development of the road traffic management needs,road traffic monitoring system has increasingly become an important component of allievating the pressure on traffic safety management departments and ensuring the safety and smoothness of road traffic.Its rational use effectively regulates the movement of vehicles on roads.The recording and evidence collection of vehicle violations are particularly important in the road traffic monitoring system.However,the color of the red traffic signal in the forensics images is different from the actual human eye recognition results.Therefore,combined with application requirements of road traffic monitoring systems,this paper analyses the reasons of the above phenomenon in terms of light transmission principle in cameras and optics characteristics of road traffic signals and proposes a method to restore the color of road traffic signals.
