基于图像匹配技术的火炮反后坐装置动态测试方法

针对目前火炮射击中反后坐装置的参数测试常规方法的一些不足，提出一种利用高速摄影机记录火炮发射状态，运用图像处理技术，采用图像匹配定位的方法，获取火炮发射状态下反后坐装置位移、速度数据，并与反后坐装置计算书的数据进行了比较。结果证明，用该方法所得数据与火炮射击时驻退后坐的运动情况基本一致，符合工程要求。说明基于图像匹配技术的反后坐装置检测技术的可行性，具有非接触、准确度高与灵活性较强等优点。

Dynamic Measurement Method of Gun Recoil Mechanism Based on Image Matching Technology

At present,the traditional parameter test method of recoil mechanism during gun firing is not enough yet,aimed at this problem,a method to record gun firing state by means of high speed camera was proposed.The method made use of image processing technology and image matching and framing methods to obtain velocity and displacement data in the state of gun recoil and counter-recoil.The tested results were compared with parameters of gun manual.The results showed that the acquired data by use of this method we...
