Information Processing Technology in the Digital Protection of Architectural Cultural Heritage

The protection of architectural cultural heritage is the requirement of the times. The application of information digitization technology plays an important role in the protection of architectural cultural heritage. The stone archways of Longquan Temple in Wutai Mountain is huge in size and complex in shape. In the process of digital protection, in order to collect massive and accurate digital 3D information, it is necessary to select different large and small scanners and other scanning equipment according to the site situation in the information collection process. The stone archway is made of white marble, which may have strong reflection, different data characteristics collected by different types of scanners, and blind spots in scanning large volume buildings. All these phenomena require proper processing. Taking point cloud data as the intermediate data of cultural heritage digitization,Different technologies and algorithms are applied to data errors and blind spots in order to achieve secondary precision carving of data, select the data and meet the requirements of high fidelity of digital information.
