摘　　要：为了提高纸靶重孔的测量准确性，提出一种基于图像减影技术的重孔识别方法．采用后一靶面图像减去前一靶面图像，得到带有当前部分弹孔信息图像．采用区域重心法求出目标区域重心位置，由此重心位置求出遮挡弹孔中心位置，从而识别出重孔位置．实验结果表明，该方法能够识别出重合面积在5％～95％之间的重孔位置．In order to improve the accuracy of the measurement of superposition hole, an approximate solution based on image subtraction technique to identify the superposition holes was put forward. After the current round target surface image minus the previous round one, the image with part of bullet information was obtained. The focus of the target area was worked out by the regional center of gravity method, then the blocked bullet hole was calculated out and the location of superposition hole was acquired. The experimental results show that it was able to identify the location of superposition hole with overlap area of 5%-95%.
