The Research on the Online Publishing Platform of Point Clouds of Chinese Cultural Heritage Based on LIDAR Technology: A Case Study of Chen Clan Academy in Guangzhou, Guangdong Province

Abstract

Cultural heritage protection has always been accompanied by production activities of human society. With the wider application of digital technology in the protection and inheritance of cultural heritage, this study intends to use the noncontact high-speed laser measurement method to obtain the 3D surface array geometry data of the typical hall of Chen Clan Academy, which is the national key cultural relic protection unit and the most distinctive artistic architecture of the existing ancestral halls in Guangdong, in the form of point clouds. Moreover, it tries to complete the automatic extraction and 3D modeling of millimeter-level accuracy images and establish the original database for cultural heritage, so as to obtain the 3D high-precision, real and measurable massive point cloud data. Independently designing the online publishing platform of point cloud data as well as realizing the browser’s rapid publishing, measurement and application of massive point cloud data can explore a new technical method for the protection of cultural heritage and the restoration and reconstruction of cultural relics in China.
