摘要
利用计算机及数码相机实现交通事故现场测量,是交通事故模拟再现系统实现的重要前提。根据交通事故现场测量需要快速的特点,分析相机成像线性模型和标定原理,并基于OpenCV实现角点提取,给出相机标定算法,最后实现了一个用于交通事故处理的图像测距系统。相对于Matlab实现方式,该系统使用更加方便、快捷。实验数据证明该测距系统适用于交通事故处理。
Measurement of traffic accident scene with computers and digital cameras is the important foundation of realizing a traffic accident simulation system. According to the need of rapid measurement in traffic accidents, this paper analyzes the camera linear model and calibration theory, realizes the corner extraction based on OpenCV, presents a camera calibration algo rithm. Finally,a distance measurement system for traffic accidents is implemented. Compared with the Matlab procedure,it is a swifter system which can be used conveniently. Experiments show that this system is suitable for traffic accidents.
