Application of Mobile 3D Laser Scanning Technology in Digital Protection of Grottoes Relics
This paper points out that the grottoes relics are the precious heritage of the development of human civilization,with high historical value,cultural value and artistic value.Due to a variety of natural and human factors,the grottoes relics are often damaged to a certain extent,so it is urgent to carry out digital protection.However,because the grottoes relics are generally embedded in the rock mass,it is difficult to acquire the data of the caves by traditional ground-based 3D laser scanning and oblique photogrammetry.Aiming at the difficulty,in this paper,mobile 3D laser scanning technology is applied to collect the point cloud data of the grottoes relics,and the real scenes inside and outside the grottoes are truly restored through 3D modeling,and the digital protection application research is carried out.The results show that the technique can provide data basis for the restoration and protection of the grottoes relics.
