Introduction of a trial 3D photogrammetry that we conducted at the site of Ta Nei Temple in Angkor, Cambodia. The technique used is SfM. This is a simple and feasible method for the local staff, permitting them to continue to document the state of the site as part of their everyday operations.

Paper long abstract:

A 3D photographic survey was conducted at the site of Ta Nei Temple in Angkor, Cambodia, as part of the cooperation project between National Research Institute for Cultural Properties, Tokyo (NRICPT) and ASPARA National Authority. The survey attempted a technique known as Structure from Motion (SfM), using open-source software and Total Station for measuring. After several proceeding steps using Visual SfM, SfM_georef and Meshlab as software, a 3D model of the site including scattered stones around the buildings could be obtained with sufficient precision to be used as basic data for research, conservation and management of the site. We tried to establish a simple and feasible way for documentation of the site, so that the local staff could continue to research and document the state of the site as part of their everyday operations without any special budgets nor equipment.
