In the existing vehicle video processing systems,due to the cameras without calibration,the information about the vehicles real size and world coordinate are unable to be obtained,which brings a series of problems.This paper proposes a framework of vehicle video processing system based on calibrated cameras and 3D vehicle model.As an example,an online recognition scheme of the escape vehicle is designed.The simulating test of the toy car shows the feasibility of dynamic model image generation for the specified vehicle object based on the camera parameters and vehicle 3D model,which is the core functional part of the whole system.
