Comparison of open-source and commercial software for 3 modeling with terrestrial photogrammetry

Abstract

Thanks to advancing computer technologies, computer programs are used in many fields instead of classical methods. Photogrammetry has become a technique accessible to many users, especially with the introduction of open-source software as well as commercial software. Thus, the use of photogrammetry in different fields is becoming widespread. In this study, a miniature statuette and calibration cube made of wood is modeled in 3D with Meshlab and Visual SFM, which are Open-Source software. On the other hand, the same small object is modeled in 3D using the commercial software Agisoft Photoscan and 3DF Zephyr. Accuracy analysis was carried out with the measured lengths on the models. RMSE was calculated as ± 0.7 mm for Agisoft Photoscan, ± 5.3 mm for MeshLab and ± 1.5 mm for 3DF Zephyr.
