不动产登记数据的建筑分层分户三维建模关键技术

随着实景三维建设的不断推进，城市管理向立体化、精细化和数字化发展，建筑分层分户三维模型能够承载更详细精准的属性信息，并能叠加倾斜三维模型进行场景渲染，可以更好地服务于城市不动产三维管理、数字赋能社会治理等工作。本文以“萧山区数字赋能社会治理”项目建设为背景，探索和实现了基于不动产登记数据的建筑分层分户三维建模关键技术，形成了从全空间多源异构数据归集至城市全域建筑分层分户三维模型建设的一整套生产技术流程，为城市不动产三维管理、数字赋能社会治理等提供了有效的技术支撑和数据基础。

Key technologies of building floor and house 3D modeling based on real estate registration data

With the continuous development of real 3D construction in China, city management is developing towards systematical, refined and digital. The floor and house 3D model of buildings can carry more detailed and accurate attribute information, and can render scene together with real three dimensional models, which can better serve the three dimensional management of city real estate and digital governance. Based on the background of "Xiaoshan district digital empowerment social governance" project construction, this paper discusses and realizes the key technology of building floor and house 3D modeling based on real estate registration data,forms technology in the manufacturing process which starts from the whole spatial multi-source heterogeneous data collection to floor&house 3D modeling of building all over the city,this technology can effectively provide technical support and data base for city real estate 3D management,digital enabling and social governance.
