Research on Dynamic Measurement Method Based on Gun Sequence Firing Image Matching

针对火炮射击环境恶劣,后坐运动动态测试相对困难的问题,提出了一种基于火炮后坐运动序列图像匹配技术的运动参数的测试新方法.建立了序列图像相关匹配及其改进算法的模型,提出了抗火炮旋转与烟雾以及提高火炮测试精度的方法,获取火炮后坐位移和速度参数.实例验证了该方法在火炮测试中的可行性.

In view of the harsh environment in which guns are fired and the fact that dynamic tests of gun＇ s recoil movement are difficult, a new movement parameters test method based on image matching technique of gun movement sequence image firing is put forward. Its advanced model of sequence image matching is built, and anti-rotation and anti-fog measures are presented. By this way, the data of velocity and displacement in the state of gun recoiling and counter- recoiling are obtained. We can draw the conclusion that the method of image matching accord with the proiect requirement as the data on both ways are almost identical.
