摘要
针对现有射击比赛用图像报靶系统无法识别弹孔重合的技术难题,研究了一种将图像采集系统和光幕传感器阵列相结合的自动报靶系统.图像采集系统利用面阵相机拍摄目标靶图像,通过剪影法判定弹孔位置,光幕传感器阵列利用反射镜将单光幕转换为具有一定角度的多光幕.该系统可以准确判定重孔位置并计算出着靶坐标.系统结构简单,测量误差不大于1mm,弥补传统图像报靶系统无法识别重孔的不足,测量精度满足使用要求,可用于各类射击训练和比赛中的自动报靶.
In order to conquer the technical problem of failing to recognize the superposition hole by the image processing system in shooting, the automatic target-scoring system with image and light screen array is proposed in this paper. The image processing system can acquire the shoot-target image,and can calculate the location of the projectile hole by image processing algorithm_ The one light screen change into the structure of the three light screens with certain angle using a mirror. The target-scoring system can accurately measure the location of the superposition hole and the coordinates of the projectile. The system structure is simple, and the measurement errors are less than I mm and this system makes up the deficiencies of the traditional image target-scoring system. Its accuracy meets the requirements, and it is applied to variety of shooting and target-reporting range.
