Underwater SfM (Structure from Motion) using moving shot images on meandering courses has evaluated. SfM extracts the position information of the feature point of the target from the multidirectional underwater photos and make three dimensional restoration data. In this study, the vision of fish swimming while meandering path was set as a clue to investigate whether it is possible to restore efficiently with few images. In this article, firstly, characteristic of restoration using moving shots with meandering course has investigated in a building. Then underwater test using a simple ROV has tried. As the evaluation method of experiment, aspect ratios of target materials on the ortho images have compared with the aspect ratio of SfM outputs.
