摘　　要：为了实现挂弹车全自动装填,缩短装填导弹时间,需要精确测量导弹挂钩与飞机挂架挂点之间的相对位置关系,提出了一种实时相对位置测量方法,详细介绍了该系统测量原理,推导出了参数测量公式,并分析了主要误差源对测量精度的影响.该系统主要由光学镜头、面阵CCD、激光器、合作目标及处理电路等组成,能够实现导弹挂钩与飞机挂架挂点之间X,Y,Z三维坐标的测量,根据仿真计算,当导弹挂入挂架瞬间,X方向测量误差为4.44mm,Y方向测量误差为0.43mm,Z方向测量误差为0.75mm.In order to shorten the time of loading a missile into the rack fixed under a airfoil automatically,the relative positional between the rack and the drawbar of missile must be measured accurately.Real-time relative position measuring method is introduced,the parameter calculating equations are derived,and the main errors that effect the precisions are analyzed.The measuring system is composed of two sets of lens,two planar array CCDs,two lasers,two cooperative objects and a data processing circuit.The system can measure the relative position information including X,Y,and Zbetween the loading vehicle and the rack.According to the simulation,the measure error is 4.43 mm in X,0.43 mm in Yand 0.75 mm in Z.
