Application of 3D Laser Scanning Technology in Grotto Protection

The high-precision 3D laser scanning technology offers the possibility to establish a set of digital grottoes that includes the complete coverage,clear details,prominent visual effects and true and accurate data.The 3D digital engineering of Yungang Grottoes is the application of 3D laser scanning technology to the production of process.It uses the laser ranging principle and it records the grotto of the 3D coordinates of the point,reflectance and texture information by the most sophisticated and reasonable technical means.It retains the complete,comprehensive,accurate,and detailed 3D data,and the resumption of the construction of the 3D model of the grotto and line,surface,volume and other data.It will clearly show the Yungang Grottoes.
