针对某型飞机上高速摄像机安装位置受限,安装在不同位置的摄像机画面不能重叠,无法采用常规影像测量交会方法计算武器分离过程的轨迹、姿态运动参数的问题,提出多视角非交叠影像测量方法。通过增加刚体目标上标志点之间相对空间关系不变约束条件,使得秩亏影像测量方程组达到满秩条件,实现了武器运动参数的测量。实验结果表明,轨迹测量精度可达到2cm,姿态测量精度可达到0.6°,满足飞行试验测试要求。

The high-speed cameras installated on a certain type of aircraft are limited, the field of cameras cannot overlap, so the routine intersection measurement method cannot be used. For this problem, the paper presents a multi-view un-overlap image measurement method. Through adding the constraint of relative spatial relations invariant between two marks on rigid object, the rank-defect image measurement equation set can reach full rank condition and then achieve the measurement of weapons separate moving parameters. The experimental results show that the accuracy of track measurement can achieve 2 cm and attitude measurement can achieve 0.6°, and which meet the fight test requirement.
