Investigation on Diseases of Tibet Murals Using 3D Laser Scanning Technology

Murals are the important components of culture and arts of Tibet. Tibet´s murals are mainly painted on the walls of temples, palaces and homes. Unhappily, these murals have been ruined or are being ruined by some diseases such as cracking, hollowing, falling off, fluid erosion, dirt, and so on. It is necessary to use new technologies to protect murals. June 2007, we, from Capital Normal University and National Institute of Cultural Property collected a lot of laser range images and digital images of Tibetpsilas murals. We proposed that integrating range data and image data to investigate mural diseases and give the location, length and area of mural diseases. Moreover, we also presented a parallel computing method to process the huge range data, and discussed to align the images into a big image based on SIFT.
