基于图像识别的模拟射击精度判定方法

摘要

针对当前瞄靶训练效率低、无评判标准,而多数模拟射击训练系统忽视瞄准过程仅注重瞄准结果的现实问题,基于图像识别的模拟射击系统在击发瞬间采集瞄准图像,通过图像处理,得出觇孔圆中心、准星顶点中心和靶纸中心,再利用灰度矩细分定位法检测各中心之间的距离.根据射击原理,运用相似三角形的比例关系,计算得出模拟弹着点的方向和高低偏移量,从而得出模拟射击的射击精度,并通过实弹射击对其进行仿真及验证.结果证明,此方法可以有效地对模拟射击精度进行计算,且能获得每次击发后正确的瞄准修正方法,可替代当前的瞄靶训练.%In the troops,the efficiency of shooting and aiming training is low,and lack of grading standards. The majority of simulate shooting training system ignore aiming process,only focuses on the results. Base on the technology of image,the system collect image at the instant of the firing,then detect parameters and measure distances about the center of peepsight,front sight and paper target in the image. On the principle of shooting,the simulate firing accuracy is obtained,it applies the law of similar triangles and calculates the x and y offset about the simulate impacts. Finally,the correctness of the simulate firing accuracy is proved that analyzing the results of simulating shooting and ball firing.It proves that the system can effectively calculate the accuracy of simulate shooting,and obtain the good correction method for aiming after each firing,and can apply in the firing practice.
