摘要
子母弹多子弹抛射情况复杂,光学测量成像点多。文中通过坐标转换法实现子弹成像点底片坐标到子弹空间坐标转换。在各帧拍摄所得多子弹成像点中,据抛射过程运动学原理,采用递推法实现同一子弹成像点判别和空间位置确定。通过仿真计算分析讨论测量过程随机误差影响,验证该方法的正确性和可行性。该方法具有较好的通用性,便于工程实用。
The tossing process of Missile Bullets is complex and there are many optical image points. In this paper, the conversion from bullet image point's film coordinate to its space coordinate is realized by the coordinate conversion method. According to the kinematics principle of tossing process, the iteration method is used to distinguish the same bullet's image point among multiple bullets' image points and determine its space position. The simulated computation results show the random error effect in the measure process and verify the accuracy and feasibility of this method which has good generality and is easy for engineering use.
