Automatic Recognization Target-reading System for Chest Silhouette of Paper

为了克服在靶场射击训练中人工报靶消耗大量的人力和时间的同时还存在诸多隐患,如误报和谎报等,本文设计了一套硬件配置相对简单、性能稳定可靠、判靶精准快速的面向纸质胸环靶的自动识别报靶系统。该系统结合嵌入式技术、图像处理技术、有线以及无线网络传输技术,实现快速检测靶面信息以及弹孔坐标。在图像处理的基础上,对图像使用区域特征消除法对干扰背景进行了消除,同时采用灰度双向肖波投影确定靶心位置,提取出靶面图像的所有有效特征信息。通过嵌入式终端、wifi通信以及网络传输等完成了整个系统的搭建。本系统具有高效、快速和判靶精准等特点。

This paper proposes an automatic recognition target-scoring system for chest bitmap with simple hardware requirement,stable and reliable performance, precise and fast scoring in order to overcome the problems that the artificial counting consumes alot of manpower, time and also there are many dangers in shooting training, such as the misinformation and the misrepresentation.Combining with the embedded technology, image processing technology, wired and wireless network transmission technology, thesystem implements the detecting of target surface information rapidly and the coordinates of bullet holes. The regional feature re-moving method is employed to eliminate background interference, and the grey two-direction clipping projection is also taken to de-termine bull's eye position based on the original picture processing. Finally, all characteristic information of the image is extractedeffectively. The system is built through the embedded terminal, Wi Fi communication and network transmission. It has the charac-teristics of efficient, fast and good scoring precision.
