Accuracy Analysis of a Dam Model from Drone Surveys

Accuracy Analysis of a Dam Model from Drone Surveys

This paper investigates the accuracy of models obtained by drone surveys. To this end, this work analyzes how the placement of ground control points (GCPs) used to georeference the dense point cloud of a dam affects the resulting three-dimensional (3D) model. Images of a double arch masonry dam upst...
