The invention provides a space target capturing method, and belongs to the technical field of spaceflight. The method comprises the following steps: enabling a space capturing aircraft carrying a monocular camera to carry out fly-around observation on a to-be-captured space target, and obtaining pose information of the monocular camera in a fly-around process; based on the pose information of the monocular camera, performing pose estimation on the space target to obtain the angular velocity of the space target; performing three-dimensional reconstruction on the space target to obtain features of the space target; and capturing the space target by using a space capturing aircraft based on the angular velocity and characteristics of the space target. According to the method, the pose of the space target can be estimated only through the monocular camera, then the spin angular velocity of the space target is calculated, the method does not depend on any existing pose estimation model, meanwhile, a three-dimensional model of the space target can be obtained, lightweight development of on-orbit spacecraft equipment is promoted, co-angular velocity capture can be carried out according to obtained angular velocity information, and the method is suitable for large-scale popularization and application. And the impact in the capturing process is reduced.

    本发明提出一种空间目标捕获方法,属于航天技术领域。其中,所述方法包括:令搭载单目相机的空间捕获飞行器对待捕获的空间目标进行绕飞观测,获取绕飞过程中单目相机的位姿信息;基于单目相机的位姿信息,对空间目标进行位姿估计,得到空间目标的角速度;对空间目标进行三维重建,获取空间目标的特征;基于空间目标的角速度和特征,利用空间捕获飞行器对空间目标进行捕获。本发明仅用单目相机就能估算空间目标的位姿进而计算空间目标自旋角速度,不依赖任何现有的位姿估计模型,同时还能得到空间目标的三维模型,促进在轨航天器设备轻量化发展,可根据得到的角速度信息进行共角速度捕获,降低捕获过程中的冲击。
