摘　　要：针对双线阵CCD交汇立靶系统测量双管武器弹丸同时着靶时会产生虚假弹着点且无法排除的问题,研究基于三线阵CCD相机交汇的双弹丸同时着靶坐标测量方法。当双弹丸同时着靶时,通过左侧和右侧CCD相机计算获得2个真实的弹着点和2个虚假的弹着点坐标,通过中间线阵CCD相机来排除2个虚假弹丸图像,以中间CCD相机探测器件的中心像元位置为原点建立直角坐标系,基于直线相交原理对弹丸的着靶坐标测量公式进行推导,对弹丸着靶坐标测量误差进行仿真和分析。仿真结果显示,在测量靶面为2 m×2 m时,横坐标测量误差的标准差小于1.5 mm,纵坐标测量误差的标准差小于2.0 mm,满足靶场对弹丸着靶坐标测量精度的要求。In order to solve the problem that false impact points will occur when dual-barrel projectiles hit the target at the same time in the measurement of dual-barrel weapon projectiles hit the target at the same time by the double linear array CCD intersection vertical target system,the coordinate measurement method of double projectiles hitting the target at the same time based on the intersection of three-linear array CCD camera is studied.When two projectiles hit the target at the same time,two real impact points and two false impact point coordinates are calculated by the left and right CCD cameras,and the two false projectile images are eliminated by the intermediate linear array CCD camera.The Cartesian coordinate system is established by taking the central pixel position of the intermediate CCD camera detection device as the origin,and the measurement formula of the target coordinate of the projectile is deduced based on the principle of linear intersection.The coordinate measurement error of projectile hitting target is simulated and analyzed.The simulation results show that when the measuring target surface is 2 m×2 m,the standard deviation of Abscissa measurement error is less than 1.5 mm,and the standard deviation of ordinate measurement error is less than 2.0 mm,which meets the requirements of projectile target coordinate measurement precision in shooting range.
