【Abstract】 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.更多还原
