红绿灯路口的交通事故对人们的生命和财产安全构成了极大的威胁。针对该问题,将双目视觉的测距技术应用在前方红绿灯距离的测量方面。研究了基于双目视觉的红绿灯距离测量系统。系统通过2个CCD摄像头从不同视角采集前方红绿灯的图像信息,得到左右两幅双目图像对,对左右两幅双目图像对进行处理、定位;然后采用全局匹配的方法进行特征点提取,找到对应的特征匹配点对,得到视差;再根据三角测量原理,恢复出被测目标的三维信息和深度信息,实现对前方红绿灯距离的测量。实验结果表明:该设计方案能有效地测量前方红绿灯距离,方法简单有效,具有较高的测量精度。

Accidents of traffic light intersection are a great threat to the safety of peopleˊs life and property. In view of this problem,applying the distance measurement technology of binocular vision ranging in preceding traffic light ranging was proposed. We studied traffic light distance measurement system based on binocular vision. Two CCD cameras were used to capture the traffic lights information that were two pieces of binocular images at the left and right from different perspectives,which were processed,positioned,and then found the corresponding matching feature points through a global matching method of extracting feature point. Thus we obtained parallax,and with it we achieved the measurement of traffic lights distance in the front and restored the three-dimensional information and depth information of the measured object according to the principle of triangulation. Experimental re-sults show that the design can effectively measure traffic light distance in the front and have high measurement accuracy in a simple and effective way.
