Sequential-image-based space object 3D reconstruction

Abstract

Space object 3D reconstruction is of important significance for both space situational awareness and theoretical study. A new structure from motion method was proposed to avoid the reconstruction error caused by the symmetrical structure and similar texture of space targets. In this method,new images were added sequentially for reconstruction using the imaging time as a priori knowledge. In addition,image simulation of space target and ground imaging simulation experiment were carried out for the lack of space target image data. And experiments on the simulated space target images,in which the motion analysis results are accurate and robust to noise,and the recovery 3D point cloud can express the structural information of the target to a certain extent,have demonstrated the effectiveness of the approach proposed,and the boundary conditions of multi-frame-image for 3D reconstruction are acquired as well.
