ANALYSIS OF 3D COASTAL TERRAIN BY UAV IMAGE AND BUNDLE ADJUSTMENT

Recently, studies on the construction of 3D terrain modeling and location accuracy evaluation using UAV have been conducted, but application to coastal areas lacking image matching points has not made in detail yet. In topography survey UAV, ortho-images DSM (Digital Surface Model) data were constructed through imaging ground control point (GCP) surveying ground. case ortho-images, VRS was used analyze horizontal vertical errors between GCP points, evaluate accuracy, construct from ortho-image data.
