The Implementation of Analysis System of Vehicle Impact Based on Dynamic Image Sequence

This paper presents the way to realize the analysis system of vehicle impact based on dynamic image sequence, and discusses some key technologies: import the method of image recovering based on atmospheric physical model to reduce the effect on image quality made by atmosphere; present the amalgamation method of background subtraction and temporal difference to realize fast detection to moving object (vehicle); establish a complete camera model based on perspective projection and distortion correction, and fulfill the 3D spatial coordinate measurement based on 2-step method. The qualitative and quantitative analysis of the impact process can be reached using this system, and the result approves its efficiency.
