摘　　要：研究了基于单目视觉的航天器相对导航方法,基于线性投影原理,建立包含图像特征与导航信息之间关系的非线性方程组。将非线性问题转化为最优化问题处理,针对该问题构建了目标函数,采用拟Newton方法解算该优化问题。进行了数值仿真,验证了该相对导航算法的有效性。The monocular vision-based spacecraft relative navigation method is researched,and non-linear equations are established representing relationship between image characteristics and navigation information,based on linear projection principle.The non-linear problem is solved by transferring to optimization problem using quasi-Newton method with corresponding objective function.Numerical simulation is also processed to validate this relative navigation algorithm.
