| 摘 要： | 为了提高传统人工测绘纸靶弹孔中心的方法中评价枪弹射击密集度时的准确性和一致性，减少人工误差，基于数字图像处理技术，提出一种纸靶圆心位置检测的数字化方法．本系统采用区域重心法，三点法和最小二乘拟合法对圆心位置进行检测．通过对实际存在的双弹孔的分析，重点解决了重孔问题．同时通过计算机编程实现了对实际纸靶弹孔的检测．根据实验数据分析了三种检测方法的优缺点及适用范围．

| Abstract: | To evaluate the fire concentration of gun,a method to measure bullet hole on paper target by man is used.In order to improve veracity and coherence of concentration parameter by the traditional method and to reduce manual errors,a new method based on digital image processing technique is introduced.The center position of a circle is obtained by center of gravity of region method,three point method and the least square fitting.Overlapping holes are mainly studied.The procedure to detect bullet holes on paper target is realized by computer programm.The characteristics and applicability of three methods are analyzed by the experiment data. |
