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.
