Abstract
In the last few years, SfM (Structure from Motion) based on photographs taken from UAV (Unmanned Aerial Vehicle) has attracted a tremendous amount of interest for the creation of DSM (Digital Surface Model) and other morphometric products. However, the accuracy of the derived DSM hasn't been sufficiently evaluated yet. Therefore, the present contribution aims to compare UAV-based SfM data against TLS (Terrestrial Laser Scanning) derived DSM data. The fieldwork was carried out on a wave-cut bench in Kanagawa Prefecture (Japan). Results have indicated that DSM data derived from UAV-SfM can create a point cloud of comparable density to the one created by TLS, with a maximum deviation of 10 cm from the TLS data. The UAV-SfM technique has a great potential for a wide range of application, because of its high data accuracy, low acquisition and operational costs, allowing high spatial and temporal data recording.
