摘要
根据透视成像原理，分析了成像过程中产生各种畸变因素，建立起成像的非线性模型。应用数字图像处理技术，编制了事故现场图像处理系统，可对现场原始图像作快速精确的三维重建。利用定制的三维生标支架，可免去全部现场测量，为再现事故现场与勘查提供了简易实用的方法与有效工具。
Based on the perspective principles and the analysis of the error of factal formation of image, this paper presents a nonlinear model which compensensated the geometric distortion of optical system. Using relative image processing technology, the program based on this model which called 'Accident image Processing System' is accomplished, it can make three dimensional reconstruction quickly and accurately by two or more accident images. By using pre-made three dimensional framework, it can free you from accident scene measurement work. It provides a new method for accident reconstruction and accident scene survey.
