3D Laser Scanning Technology Application In The Field Of Protection For Petroglyph

3D laser scanning technology is an international high-tech development in recent years, the use of 3D laser scanning technology for the space clouds, can quickly create complex, irregular 3D visual model of the scene for the accuracy of the science establishment of data model provides a new technical means.In this paper, 3D laser scanning technology, the Jiangjunya Petroglyph of digital protection; main contents of this paper is as follows:Using 3D laser scanner, Jiangjunya Petroglyph of the 3D geometric information, on-site operation of selected equipment, scanning the site design guidelines, comprehensive high-quality data collection.By cyclone and geomagic software, there is some cloud to the data processing method, the realization of the ancient petroglyph of the data reduction, multi-station data registration, the 3D model of geometric modeling and repair and so on. Mapping system using coaxial realized 3D model of the texture mapping.Using the point cloud data and 3D model of the Jiangjunya Petroglyph digital files for restoration and protection of accurate first-hand information, and for the petroglyph provide an important reference for research.
