摘　　要：提出了一种基于图像处理的激光打靶仪设计方案,并介绍了系统的组成和设计思路。系统使用摄像头采集靶面图像,采用背景差法确定弹着点。摄像头动态捕获视频靶面图像,并把前一时刻采集到的图像作为背景图像,在开始射击时,新捕获到的图像必然发生一些改变,与前一时刻得到的背景图像做减运算,发生改变的像素部分就是激光脉冲打到靶面的位置。此设计可以准确地模拟实弹射击训练,满足射击训练的要求。A design method of laser simulated shooting trainer based on image processing is proposed. The system compo- nents and design ideas are introduced. In this system, the target images are acquired with camera. The background difference method is used to determine the point of shooting. The camera dynamically captures the target surface vedio images, and find out the shooting point by subtraction with the previous frame. This design can simulate shooting training, and meet the training requirements.
