基于星箭对接环同心圆结构的卫星姿态估计方法
Satellite Pose Estimation Method Based on Concentric Circle Structure of Docking Ring
摘要
Abstract
Using single circle feature of docking ring to estimate pose of satellite has two solu-tions,which cannot be easily applied to practical applications.In this paper,the docking ring is treated as a concentric structure composed of inner and outer rings,so the normal vector of the spatial ring can be resolved according to the algebraic constraints of the concentric circles.Then the attitude of target satellite relate to tracking satellite can be determined.Several groups of sim-ulation experiments are carried out to calculate and analyze the pose estimation error with differ-ent measuring distances and noise levels.The monocular vision-based pose estimation of the doc-king ring with unknown diameter and uncertain center is achieved and verified without any extra measurement information.The result can provide the support for pose estimation of space non-cooperative obj ect.关键词
