Abstract: To address the problem of data loss in the reconstruction or modeling process of single data source in the salvage digital preservation project, this paper combines multi-source data, taking the Huanxiu villa Haitang pavilion as an example, and adopts the coordination of “space-land-people” to strengthen the collection of spatial information of the Haitang pavilion, including the survey of basic information of the building and the mapping of the building ontology, so as to build a salvage digital preservation project with high-quality live 3D model. The high-quality realistic 3D model of the digital protection project retains a full range of data and information for the ancient architecture. On the one hand,it provides detailed information for the formulation of long-term management mechanism for the protection of ancient architecture, maintains the virtuous cycle of architectural protection and utilization, realizes the revitalization and updating of ancient architecture, and achieves the retention of a full range of ancient architectural and high-precision status quo information. On the other hand, it provides information for the scholars to study the traditional architecture of China, promotes the inheritance of traditional architectural crafts, and provides powerful data support for the restoration and reconstruction of ancient buildings in the future.
