The purpose of this paper is to investigate the applicability of the simple UAV to the field survey by performing the reality capture from the videos and images taken by simple UAV.
The survey was carried out in Seisho Coast, where significant erosion due to waves has been observed, focusing on changes in structures such as sandy beaches and blocks.
As a result, it was found that a simple UAV can perform sufficient shape grasping and field survey. and it was concluded that the accuracy of the shape grasping was significantly different due to the camera resolution and flight method of the UAV.
