A composite camera calibration method is presented, in which step-by-step calibration based on coplanar targets is taken in the process of determining the extrinsic and intrinsic parameters of camera and the least squares method is taken for solving radial distortion parameters and further iterative optimization. Moreover among the identification of calibration points, the encoding unit is introduced...
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...
