Three Dimension Reconstructing Of Historic Architectures

The development of three-dimensional computer graphics makes the goal that people rebuild the real world in the virtual digital environment become possible. The digital three-dimensional model, which including more abundant information than the two-dimensional model, is closer to people's daily living space. Three dimension reconstructing of historic architectures can record space position, architectural style, inside structure of the building vividly and abundantly. Three-dimensional model of historic architectures offers basic data and materials for work, such as dossier and renovating of the building.This paper, taking plane building of hospital of CHANGHAI as an example, introduces a scheme that gathering the three-dimensional space information to the historic building by digital close range photogrammetry and architectural survey, utilizing digital image processing and computer graphics technology to rebuild the three-dimensional model of historic building. The main content of the paper includes: Scheme design that the historic building three-dimension rebuilt;Utilize digital close range photogrammetry to gather the texture of the building;rebuilding the three-dimension model of the building and releasing it on the internet.
