Abstract
In recent years, UAV (Unmanned Aerial Vehicle) attracts attention as a method to easily photograph aerial images with low ground resolution. Three-dimensional modeling software using SfM (Structure from Motion) and MVS (Multi-View Stereo) is generally used for three-dimensional measurement using this UAV aerial images. However, it is pointed out that these trends are different from each other. Therefore, in this research, we extracted features from two experiments, Pix4D and PhotoScan, which are currently in wide use, and compared the differences between them. As a result, we found that the lens distortion correction is different in each software, PhotoScan is beautiful in appearance but weak in displacement extraction, Pix4D is swaying in Z value but strong in displacement extraction etc.
