Testing SfM Software With Large Frame Sensors

Abstract

As of today, there are no publications discussing the utilization of Structure from Motion (SfM) software specifically for images captured using large frame sensors. Therefore, this study aims to explore the application of SfM software with large frame sensors. For this purpose, the images collected with a large frame sensor are processed using Trimble Inpho and Agisoft software. Ground control points are used as the baseline. In terms of 2D residuals, when five control points are used to process the data, Agisoft produced results within the ground control accuracy. When no control points are used to process the data, Agisoft results exceeded the ground control accuracy, especially in the Z coordinate, which produced approximately one order of magnitude larger bias.
