在航天测控靶场中,空中飞行器三维姿态测量具有不可替代的作用。利用数字摄影测量的严密理论和计算机视觉的前沿成果,提出利用光电经纬仪拍摄的序列影像确定飞行器三维空间姿态的方案,改变以往将飞行目标当作质点处理,无法获取飞行目标三维姿态参数的现状,充分利用光测图像中的姿态和形状信息,通过建立经纬仪摄像机模拟成像系统,实现飞行器目标的姿态预测。
In spacecraft TT & C range, three-dimensional attitude measurement of aerial vehicles plays an irreplaceable role. Based on the rigorous theory of digital photogrammetry and the forefront achievements of computer vision, this paper proposes a scheme of determining the attitude of the aircraft in three-dimensional space using sequence images taken by the theodolite, and changes the status of the past three-dimensional attitude parameters of the flight target, Making full use of the pose and shape information in the photometric image, the attitude prediction of the aircraft target is achieved by establishing a theodolite camera simulation imaging system.
