The calculation of the amount of bricks used in the area of falling-off is of great significance to the restoration of the ruins of ancient cities In order to support the digital restoration of the city wall of Puzhou Ancient City Site, this paper analyzed and calculated the amount of outer cladding brick of the city wall based on SLAM data. Firstly, the point cloud data of Puzhou city wall is obtained by SLAM technology. Secondly, the original point cloud is processed by Geomagic Studio software, and the area of the damaged area is accurately measured from the packaging model.
