Abstract
Structure from motion (SFM) matching algorithm is the basic principle of new generation and widely used image matching software. Although these software work in common principle, their final products may contain different characteristics and distortions depending on their buried parameters. In the literature, there is lack of publishments which compare the three dimensional modelling performance of SFM based new generation software. Accordingly, our research group decided to carry out a study that could be a reference for upcoming researches. In this study, using VisualSFM, Agisoft and Pix4D SFM based image matching software, 3D digital surface models (DSM) were generated from unmanned air vehicle (UAV) high resolution aerial photos in a Campus of Zonguldak Bulent Ecevit University. Generated DSMs were comprehensively evaluated and compared by visual and statistical approaches utilizing the Agisoft DSM as the reference. The results clearly demonstrated the pros and cons of each analyzed SFM-based software.
