| 摘 要： | 枪械射击准确度是枪械验收的一项重要指标。为提高验收精度、降低验收成本,针对现有验收方法的不足,提出了光电成像并结合图像处理的验收方法。根据成像的图像特点和验收的实际要求,采用模板匹配算法识别代表瞄准线的十字分划,拟合枪管轴线并用十字分划表示,通过检验两十字之间的角度关系来进行射击准确度的验收。研究结果表明,采用模板匹配算法,十字分划的识别精度小于1个像素,射击准确度验收系统的精度约为0.26 mil。

| Abstract: | Firing accuracy is a key evaluation index of gun acceptance testing.A novel gun acceptance method,which can improve acceptance precision and reduce acceptance cost,is proposed to ameliorate conventional acceptance methods.To conduct gun acceptance testing,angular dependence between aiming line and axis of barrel is inspected,based on image processing of template matching.The results show that the recognition precision of the template matching method is less than one pixel,and the firing accuracy acceptance ... |
