摘要
针对目前弹丸动爆实验组织难,系统复杂等问题,论文提出了一种基于视频图像计算弹丸终点参数的新方法,简化了动爆实验所需的复杂测量系统平台,通过视频图像中弹丸位置姿态的提取计算弹丸终点参数。论文采用了改进的减背景法进行目标定位与跟踪,根据弹丸边界确定弹丸姿态,再由投影变换和立体视觉原理求得目标实际位置和姿态,并运用VC2010和OpenCV2.2软件平台设计了仿真系统。系统仿真结果表明论文方法实用可行,运算速度快,精度较高。
Aiming at the problems of projectile explosion experiment difficult organization and system complexity, a new method for computing projectile terminal parameters based on video is advanced in this paper. The method simplifies the complicated measuring system platform for projectile explosion experiment, instead that, the projectile terminal parameters are extracted from its position and attitude in the video image. An improved background subtraction is used to locate and track target in the paper, and the projectile attitude can be ascertained by its verge, then the real position and attitude of the target are figured out according to projection transformation theory. Lastly, a simulation system is designed by using VC2010 and OpenCV2.2. Result shows that the method practices well, runs fast, computes accuracy, etc.
