Through the intersection of digital technology and culture, it provides more diversified support for the diversified display, expression and experience of housing cultural heritage, thus generating a more multi-level and expressive interactive experience. In this study, a digital twin architectural model of housing cultural heritage is established based on point cloud modeling and finite element modeling, and combined with the field survey data of housing cultural heritage. Subsequently, the digital curation of housing cultural heritage is realized with the architectural modeling technology and virtual interaction technology. The digital model of housing cultural heritage constructed by the method proposed in this paper has a high degree of similarity with the housing building entity, and the average offset distance of the basic unit points is only 0.034 meters. The results of the case study show that the housing cultural heritage has been effectively protected after the implementation of digital curation, and the mean scores of the assessment of environmental, historical, scientific, and cultural values are between 8.25 and 8.99, which indicates that digital curation plays an important value in the innovative protection of housing cultural heritage. The significance of the research in this paper is that it accumulates original information for the digital preservation of housing cultural heritage and provides theoretical basis and technical support for more digital innovative preservation of housing cultural heritage.
