A traffic accident scene swift reconnaissance system of vision

Abstract

The current traffic accident scene investigation method can not meet the demand of the social and transportation, considering the situation, a traffic accident swift reconnaissance system based on the new technology of computer vision is proposed. Imaged the coded targets distributed in the accident scene by the CCD camera in several locations and orientations, making use of the uniqueness and geometric constraint of coded target, can realize automatic recognition and match of coded target, then use bundle adjustment to calculate the initial external location and orientation of each camera and the 3D coordinate of space feature points, at last, the final three-dimensional information of the traffic accident scene is get with high precision. The whole solving process is done automatically, so it is fast and objective. The experiment results demonstrate that the method is feasible and flexible.
