3D reconstruction of non-cooperative target based on line correspondences

Due to the development of aerospace technology in China, this paper proposes a method of characteristic line detection and matching to reconstruct the non-cooperative target. The geometric and algebraic constraints are given by its 2D images, and the linear equations about position and attitude of the aircraft relative to the non-cooperative target are deduced by n lines (n > 13). Then, by using the least-square method, the aircraft's motions are obtained. Lastly, the 3D target is reconstructed by utilizing aircraft's position and attitude. The extensive experiments over simulated images and parameters demonstrate the robustness, accuracy and effectiveness of the proposed method.
