DISCUSSION ON RESTORATION DESIGN OF LANDSCAPE SITE BASED ON 3DTERRESTRIAL LASER SCANNING : A CASE STUDY OF QIWANG HALL IN SUMMER PALACE, BEIJING, CHINA

Abstract. In recent years, new technologies have been developed and applied in the field of heritage conservation, such as Three-dimensional-terrestrial laser scanning (TLS). The academia pays more attention to the heritages which remain relatively intact, but neglects those destroyed. Research on information collection and restoration of sites helps to better protect the damaged sites and deepen people's understanding of the value of heritage. This study will conduct a detailed survey of the status quo of the site, providing basic information for the protection of the site. At the same time, the existing archives and documents are excavated and sorted out, and the restoration research of Qiwang Hall is carried out on the basis of the site and archives, which can make up for the shortcomings of the previous research and provide a reference of methods for the relevant research.
