摘　　要：为了测量某型号反坦克导弹的发动机点火时间,采用高速摄影和Matlab图像处理相结合的方法,将拍摄的素材进行图像处理、选取特征点,得出弹丸位移、速度曲线,根据速度曲线的拐点确定发动机的点火时间,结果与多普勒雷达测得数据吻合度较高,说明此方法适用于测量导弹发动机点火时间,且具有操作简单、试验成本低等优点。In order to measure the engine ignition time of a certain type of anti tank missile,the method of high-speed photography and MATLAB image processing was used to process the image of the photographed material,select the feature points,obtain the displacement and velocity curve of the projectile,and determine the engine ignition according to the speed inflection point of the curve.This method is suitable for measuring the ignition time of missile engine,and has the advantages of simple operation and low test cost.
