Abstract: Aiming at the disappearance of feature points in the scene of ultra close docking of reconfigurable spacecraft modules，a high-precision relative pose measurement method based on visible light/laser was proposed.According to this method，the initial relative roll angle error is corrected by the combination of visible light and laser，and the coarse calibration is completed.Then，the accurate relative pose is calculated by laser two-dimensional double mirror reflection method to obtain high-precision relative pose data.The simulation results show that，under the existing technical conditions，this method can realize the relative pose measurement accuracy of ±1.2mm and ±0.03° without relying on visual feature points when the relative distance of the module is within 100cm，which lays a foundation for the ultra close and highprecision pose control of the module spacecraft docking.
