摘要
多媒体计算机序列图像运动分析系统与摄影测量学理论相结合,成为较完善的非接触动态测量系统.在乘用车侧面碰撞试验中采用图像采集和数字图像处理技术,结合直接线性变换(directliner transformation,DLT)算法,分析碰撞试验中标示点的变形量,提高乘用车侧面碰撞强度,为汽车被动安全性研究提供依据.
A comparativeIy 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 anticoIlision performance.
