ANALYSIS OF 3D COASTAL TERRAIN BY UAV IMAGE AND BUNDLE ADJUSTMENT. (2023). Coastal Engineering Proceedings, 37, sediment.18. https://doi.org/10.9753/icce.v37.sediment.18
Resumen
Recently, studies on the construction of 3D terrain modeling and location accuracy evaluation using UAV have been conducted, but the application to coastal areas lacking image matching points has not been made in detail yet. In coastal topography survey using UAV, ortho-images and DSM (Digital Surface Model) data were constructed through imaging and ground control point (GCP) surveying on the ground. In the case of ortho-images, VRS survey was used to analyze horizontal and vertical errors between GCP points, to evaluate accuracy, and to construct terrain data from the ortho-image and DSM data.Referencias
