为了解决10 m气步枪运动员日常训练中需要消耗大量子弹和靶纸的问题, 使用LabVIEW设计了一套基于图像处理技术的激光模拟射击自动报靶系统。此系统在10 m气步枪基础上加装扳机压力传感器、蓝牙模块、激光器等, 使用激光束代替实弹, 使用摄像头模块捕捉靶纸上的光斑图像并传输给计算机程序, 利用LabVIEW程序的图像处理函数进行处理得出瞄准轨迹、扳机压力曲线和环数成绩等提供给教练及运动员查看分析。相比与传统的人工判靶, 该系统除了解决训练中消耗大量子弹和靶纸的问题, 还在报靶的效率、精度、公平性等方面具有一定的优势。

To solve the problem that a large number of bullets and target papers need to be consumed in the daily training of ten-meter air rifle athletes, a laser simulation shooting automatic target-scoring system based on image processing technology with LabVIEW is designed. This system is equipped with trigger pressure sensor, bluetooth module, laser, etc. on the basis of ten-meter air rifle. The laser beam is used instead of the live ammunition. The camera module is used to capture the image of the spot on the target paper. The image processing functions of the LabVIEW program is presented to process the aiming trajectory, trigger pressure curve and scores for coaches and athletes to view and analyze. Compared with the traditional manual judgment, this system not only solves the problem of consuming a large amount of bullets and target paper during training, but also has certain advantages in terms of efficiency, accuracy and fairness of the target.
