Based on binocular vision system,a relative states autonomous determination algorithm for the close range flying phase of spacecraft rendezvous and docking was developed in this paper.With the modified Rodrigues parameter as attitude variable,the kinematics and dynamic equations of relative attitude and relative motion were established.The mathematical model of binocular vision system was set up.The relative position and attitude as well as their changing rate of two spacecraft using extended Kalman filtering were obtained.The simulation results showed that the proposed algorithm was valid.
