In the era of Internet plus, the digital technologies are of rapid development. With the normalization of the epidemic, the post-epidemic era is foreseeable, and digital museum is becoming a cultural trend, which meet the needs of art, culture, life and other normalized of society. As the basic branch of architectural education, the making, display and storage of architectural models have the dual significance of artistic value and learning exchange. In order to break the boundaries of time and space, as well as integrate teaching resources, the project using 3d scanning, network interaction and other digital technologies, realized the construction of digital virtual architectural model exhibition hall. This paper discussed and practiced a series of technical problems related to real data virtualization, such as data acquisition of physical building model, data matching of digital modeling, whole data processing process, holographic display of virtual platform, online interactive means of network. A systematic and complete digital architectural model online display process is proposed. It provides basic materials for the digital teaching of architecture education in the future, and promotes the learning exchange within architecture disciplinary and interdisciplinary.
