In the era of internet plus, digital museum is becoming a cultural trend. As the basic branch of architectural education, the making, display and storage of architectural models have dual significance of artistic value and learning exchange. In order to break the boundaries of time and space, as well as integrate teaching resources, using 3D scanning, network interaction and other digital technologies, the project realizes the construction of digital virtual architectural model exhibition hall， which is ahead of domestic architectural universities. This paper discusses and practices 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 network interaction. A systematic and complete digital architectural model online display process is proposed.
