摘要
计算机视觉摄影测量模型是通过计算机视觉进行事故现场测量系统设计的基础。根据摄像机成像基本关系，建立了描述空间点及其二维成像间的摄影测量数学模型，考虑了成像系统的对称性镜头畸变误差，建立了线性摄测数学模型，通过试验分析了模型的理论精度和标定精度。
The photogrammetric model of computer vision is the fundamental for traffic accident sence measurement system. According to the basic relationship between the spatial points and their image points, the photogrammetric model for camera calibration and sence measurement is built. A linear model is also developed in which the symmetrical lense distortion has been considered. The theoretical and calibration accuracy is analyzed through the experiments.
