Recording and Restoring the Color Texture and Geometric Information of Cultural Heritage

The main approaches currently used for digital preservation of historical architecture heritage are 3D scanning. These approaches have successfully realized the acquirement of 3D shapes of architectural heritages. But due to some critical constrains, they still cannot provide enough support for recording high quality color and texture information so far. In the mean time, large amount of information of point cloud acquired by 3D scanning also create big challenges for data processing and digital content utilization. We adopted an entirely new ways and techniques in the process of digital preservation of ancient buildings in Foshan Ancestral Temple & Donghuali area, which employed High Dynamic Range Image (HDRI), panoramic imaging, photogrammetry measurement to record geometry information together with accurate color texture information of cultural heritage. In addition, some practical applications of digital content were also carried out, which shows a promising future of our methods.
