| Abstract: | A comparatively perfect non-touch measuring system was proposed,which combines the photogrammetry,with computer multi-media technology,and was applied in side-collision experiment of riding vehicle.The image acquisition and digital image processing technology were used in the experiment,united with the DLT algorithm.The distortion at the collision signed point was analysed in order to improve the anticollision performance. |
