Spacecraft Pose Estimation Based on Different Camera Models

Abstract Spacecraft pose estimation is an important technology to maintain or change the spacecraft orientation in space. For estimation, when two are relatively distant, depth information of space point less than that measuring distance, so camera model can be seen as a weak perspective projection model. In this paper, algorithm based on four symmetrical points outline proposed. The analytical solution obtained by solving model, which satisfy requirements measurement distance long. optimal from meet small. simulation results show proposed obtain better results, even though noise large.
