Data Fusion of Unmanned Aerial Vehicle (UAV)-Based Photogrammetry and Close-Range Photogrammetry in Historical Sites Monitoring

Abstract

There are various methods for monitoring historical sites ranging from classical drawing techniques to, classical surveying techniques etc. Along with developing technology, modern methods have become more preferable to classical methods. In this context, UAV-based photogrammetry and close-range photogrammetry appear as popular methods for historical sites monitoring and documentation studies. It can be said that each method has its own advantages and disadvantages. In this study, a historical monument was modeled by using UAV-based photogrammetry and close-range photogrammetry. Then, two models were integrated with each other in order to have a complete representation of the object to be modeled. The metric accuracy of the resulted model was also investigated.
