为对纸靶法获取的弹孔图像进行数据判读以测量弹丸飞行状态参数，提出了一种新的数字化图像采集与处理纸靶弹孔的方法，其核心是弹丸三维模型正投影匹配搜索算法，可实现弹丸穿靶姿态、位置的高精度测量。实验结果表明，利用该方法采集靶纸上的弹孔图像简便易行，分析和处理的自动化程度高、受人为主观因素影响较小，且测量精度优于传统方法。该方法在已知三维模型的弹丸章动纸靶数据处理中有较强的适用性。

To process the proj ectile hole image on yaw card to measure the parameters of proj ectile flight attitude,a new collecting and processing method about proj ectile hole digital image on yaw card for proj ectile flight attitude and position was presented.The main idea of the method is com-putational searching algorithm based on matching of the bullet model’s orthographic proj ection. The result shows that the proj ectile hole image on yaw card can be collected and processed efficiently by this method.Using this method,operation means is brief and convenient.The automation degree of analysis and process is high,and man-made effecting factor is little,and the accuracy of processing result is more higher than traditional methods.If 3D model is known,this method is strongly applicative.
