Therefore, instead of reconstructing the detailed surfaces, we aim to recompose the scene with CAD models retrieved from a given dataset to faithfully reflect the object geometry and arrangement in the given sc ene. Moreover, unlike most of the previous works on scene CAD recompositio n requiring an offline reconstructed scene or capture video as input, whic h leads to significant data redundancy, we proposed a novel online scene C AD recomposition method with autonomous scanning, which efficiently recomp oses the scene with the guidance of automatically optimized Next-Best-View (NBV) in a single online scanning pass. Based on the key observation that spatial relation in the scene can not only constrain the object pose and layout optimization but also guide the NBV generation, our system consists of two key modules: relation-guided CAD recomposition module that uses re lation-constrained global optimization to get accurate object pose and lay out estimation, and relation-aware NBV generation module that makes the ex ploration during the autonomous scanning tailored for our composition task . Extensive experiments have been conducted to show the superiority of our method over previous methods in scanning efficiency and retrieval accurac y as well as the importance of each key component of our method.\n\nRegist ration Category: Full Access\n\nSession Chair: Sai-Kit Yeung (Hong Kong Un iversity of Science and Technology) URL:https://asia.siggraph.org/2023/full-program?id=papers_317&sess=sess123 END:VEVENT END:VCALENDAR
