Reconstruction of the Ancient Pagodas

The reconstruction of the damaged historical building, pagoda and temple is a critical task in disaster recovering process. In Myanmar, many pagodas are destroyed due to the earthquake. In this research, 3D reconstruction approach is proposed for estimating the structure of the pagoda before earthquake from the 3D stricture of the damaged pagoda after earthquake. It will provide to renovate the pagoda with original structure. The post-earthquake images are acquired using the Unnamed Aerial Vehicle (UAV) and generate the point cloud data. To estimate the 3D vertices of the top and boundary of pagoda, the intersection vertices of line and curve are computed based on Hough transform. Furthermore, the proposed system can detect the complete structure of the whole pagoda.
