Therefore, instead of reconstructing the detailed surfaces, we aim to recompose the scene wit h CAD models retrieved from a given dataset to faithfully reflect the obje ct geometry and arrangement in the given scene. Moreover, unlike most of t he previous works on scene CAD recomposition requiring an offline reconstr ucted scene or capture video as input, which leads to significant data red undancy, we proposed a novel online scene CAD recomposition method with au tonomous scanning, which efficiently recomposes the scene with the guidanc e of automatically optimized Next-Best-View (NBV) in a single online scann ing pass. Based on the key observation that spatial relation in the scene can not only constrain the object pose and layout optimization but also gu ide the NBV generation, our system consists of two key modules: relation-g uided CAD recomposition module that uses relation-constrained global optim ization to get accurate object pose and layout estimation, and relation-aw are NBV generation module that makes the exploration during the autonomous scanning tailored for our composition task. Extensive experiments have be en conducted to show the superiority of our method over previous methods i n scanning efficiency and retrieval accuracy as well as the importance of each key component of our method.\n\nRegistration Category: Full Access, E nhanced Access, Trade Exhibitor, Experience Hall Exhibitor URL:https://asia.siggraph.org/2023/full-program?id=papers_317&sess=sess209 END:VEVENT END:VCALENDAR
