reconstruction of geometric structures from images using supervised learning suffers from limited available amount of accurate data. one type of such data is accurate real - world rgb - d images. a major challenge in acquiring such ground truth data is the accurate alignment between rgb images and the point cloud measu... | arxiv:2110.03249 |
