A New Test System for Vehicle Deflection

Vehicle deflection brought serious consequence, so the vehicle deflection test system need to develop. Based on close-range photography and image process, the vehicle deflection test system is a new vehicle test system. The system composition, test principle and key technology are introduced, and the tolerance analysis is made. The system uses non- contact measurement and has high precision. Using digital information, achieve real-time automatic computation, high speed and high reliability. This system will be widely used in complete vehicle manufactures with production efficiency.
