Abstract: Due to the special characteristics of the installation location for testing camera in the flight test of a certain type of airborne weapon, the field intersection area of camera is smaller, so as the trajectory and attitude motion parameters of the weapon delivery process cannot be calculated by using the conventional image measurement method.Aiming at this problem, a set of scheme for measuring airborne weapon delivery test image under conditions of close range and large dip angle was designed.Through designing the 90° bend lens and the 120° bend lens to change the camera mounting position, the problem of weapon delivery image acquisition was solved.By establishing the large dip angle multi-camera data-joint calculation model, the trajectory and attitude measurement of the weapon was realized.The simulation results show that using the maximum trajectory measurement error by this program is less than 2 cm, which can meet the flight test accuracy requirements.
