基于双目视觉原理,建立了空间目标的三维坐标计算模型,利用安装在捕获端的摄像头对主星进行观测,建立了捕获端定姿方法。仿真算例验证了所提方法能够以较高的测量精度实现定位和测姿,可以满足绳系卫星捕获端的姿态确定精度需求。 Based on the principle of binocular vision, a three-dimensional coordinate calculation model of the space target is established. The main star is observed by a camera installed at the capture end, and a method of capturing the end position is established. The simulation results show that the proposed method can locate and measure the position with higher accuracy, and meet the demand of attitude determination accuracy of tethered satellite.
