摘　　要：为测量弹丸在弹道上任意时刻的速度,通过对某火箭破甲弹进行高速摄影图片拍摄,采用边缘识别、阈值处理、RGB识别算法对图片进行识别,分析比较不同图像处理算法并利用Matlab软件进行数值仿真,消除拍摄污点与环境噪音的干扰,识别火箭发动机工作期间图片中破甲弹的位置,动态测量各帧图片间破甲弹的位移,绘制出射程与时间的连续曲线,进而得到弹丸的速度曲线。最终得出最优的飞行弹丸图像处理方式,以实现高速摄影对弹道特性的研究。For measuring the speed of projectile on the ballistic at any time,through the high speed photography pictures of a rocket high explosive anti-tank cartridge,the edge detection,threshold processing,RGB recognition algorithm are used to recognize the image.Analyzing and comparing different image processing algorithms and using Matlab software for numerical simulation,photographic stains and environmental noise interference are removed.The position of the high explosive anti-tank cartridge in the picture is identified during the rocket engine operation,dynamic measurement of projectile displacement between each frame.By painting the continuous curve in the range and time,the speed curve of projectile is obtained.Finally,the optimal flight projectile image processing method is obtained to realize the study of trajectory characteristics by high-speed photography.
