Research on 3D Reality-based Modeling and Virtual Exhibition for Cultural Sites -Taking the Small Wild Goose Pagoda in Tang-Dynasty as the Case
Taking the Small Wild Goose Pagoda in Tang Dynasty as the case, this paper mainly researches the key technologies of 3D reality-based modeling from real data and of 3D virtual exhibition of cultural sites. Firstly, this paper puts forward the method of 3D digital data process of cultural sites by way of combining the technologies of the 3D laser scanning of the large scenes and the digital photography, which enables prompt and accurate digital data acquisition without damaging the cultural sites; then based on the laser-synchronized visual image of ancient buildings, the paper proposes the method of 3D reality-based modeling from real data with the adoption of the local texture mapping; finally, the paper introduces the systematic architecture, technology roadmap and key technologies of the 3D virtual exhibition system based on WebGIS for the cultural sites. The implementation of the methods proposed in the paper can not only create a reality-based 3D digital modeling of the Small Wild Goose Pagoda, which helps to realize the digital protection of this important cultural site built in 707 AD, but also create a digital object with 3D virtual exhibition function so that people can enjoy its unique historical, cultural and tourist values based on the Internet
