摘要射击训练作为士兵训练的必备项目，一直是部队重点关注的。然而目前仍然采用的是传统的射击训练，即实弹训练。这样的训练方式不仅浪费弹药资源，而且训练效率低下，安全问题很大程度上限制了士兵的训练成效。而且传统的人工报靶方式使得训练的公正性，可靠性无法得到保障。随着激光技术的不断发展，以激光代替实弹进行射击训练已成为各国不断努力转变的趋势。

本课题主要针对激光打靶系统第二部分的靶面信号提取分析设计了一套系统。该系统利用CCD摄像机采集靶面图像，经由视频采集卡吧模拟图像转换成数字图像，通过图像处理技术对图像进行预处理，利用背景差法提取光斑，继而进行识别判靶，最终得出打靶成绩。22344
本系统有效地解决了人工报靶可靠性差、公正性安全性低等问题，而且成本低，操作简单，具有很好的发展前景。

Title The Research Of The System Of Laser Shooting Signal Processing
Abstract
As an essential practice of military training,shooting practice is always
focused by army.However,the traditional practicing system is still adopted
in the army of every country nowadays.This training method not only waste
much resource of ammunition,but also lower the training efficiency and low safety issues largely limits the effectiveness of training soldiers.
And the training impartiality and reliability can not be guaranteed by
the traditional way of artificial results reporting.With the continuous development of laser technology, it has become a tend that each country
makes efforts to substitute laser for ammunition to make shooting practice.
This research is made to design a system for the signal extraction and
analysis of the target surface which is the second part of the laser
shooting system .This system captures image by CCD video camera.Then
converting the analog image into a digital image by video capture card.
We can preprocess the digital image through the image processing
technology .And the laser spot can be extracted by the background difference method.Then the score of the shooting training can be got .
Those problems which are caused by the artificial results reporting method is dealt efficiently by this system.And this kind of system is low cost,simple operation,and this system will have a good prospect for development.
