Application of 3D Laser Scanning Technique in the Conservation of Geotechnical Cultural Relics in China

3D laser scanning (LS), as a new, high-level technology of mapping and information, has undergone drastic development during recent years, and plays an important role in the conservation of cultural relics (CR). The paper summarizes the features of 3D LS technology, and puts much emphasis on the introduction of its application in information retention (IR), virtual restoration (VR) and supervision of CR information. Finally, it is pointed out that the development and application of 3DLS technology in the conservation of geotechnical cultural relics (GCR) should closely follow the need in cultural relic conservation (CRC). Besides, the modification and improvement of hardware and software as well as the integrated application of related techniques is also the significant research orientation.
