This paper presents a study on the accuracy assessment of 3D models generated through photogrammetry for monument restoration using Building Information Modeling (BIM) software. The point-to-plane distance equation was used to calculate the accuracy of the 3D models, and a root mean square error (RMSE) calculation was performed to compare the coordinates of specific points on the actual building with the coordinates of the corresponding points on the 3D model. The types of photogrammetric methods, including aerial and terrestrial photogrammetry, were also discussed, along with the two main techniques of terrestrial photogrammetry: close-range photogrammetry and industrial photogrammetry. Agisoft Metashape was used for close-range photogrammetry applications. The results showed that the point-to-plane distance equation and RMSE calculation are effective tools for assessing the accuracy of 3D models generated through photogrammetry for monument restoration using BIM. © 2023 IEEE.
