EXAMINING ARCHITECTURAL PROJECT APPLICATIONS WITH PHOTOGRAMMETRIC POINT CLOUD: IĞDIR UNIVERSITY MOSQUE

Abstract

In accordance with the developments in today's technology, the use of unmanned aerial vehicles in architectural documentation and 3D modeling studies is becoming increasingly widespread. When the studies in the literature are examined, it is seen that they focus on the documentation and 3D modeling of historical buildings. In this study, unlike the research in the literature, the usability of UAV photogrammetry in architectural project implementation and monitoring is investigated. In line with this aim, 3D point clouds and 3D models were generated using UAV photos in the study. For the identified reference points, measurements obtained from architectural project drawings, measurements taken on-site using the measurement technique with a laser meter, and finally the comparison of the measurements corresponding to these reference points on the 3D model produced from UAV photos were conducted. Based on the obtained data, when the detailed measurements taken with a laser meter are compared with the detailed measurements taken from the 3D model obtained with UAV, the consistency level is observed to be an average of 98% and above. Thus, the accuracy of the measurements obtained using UAV photogrammetry has been proven. Additionally, it was observed that measurements taken with a laser meter from the same reference points on the architectural project were different. The reason for this is the modification of the forms of details in the implementation phase of the architectural project. In this regard, it is thought that obtaining precise measurements on photos taken with UAV photogrammetry will provide an important groundwork for future studies on architectural project implementation and monitoring.
