| Abstract(in English) | In this research, we propose a novel method for registering X-ray images to CT volumes by reconstructing 3D point clouds and 2D image point matches. Previous methods have utilized mutual information and correlation as the distance function for comparing digitally reconstructed radiographs with target X-ray image for registration. These methods require good initial pose estimates otherwise the optimization would result in local minima. In order to obtain an automatic registration pipeline, we utilize 3D reconstruction network and traditional camera estimation techniques using dense 2D-3D correspondences. |
