Using Stereo Matching 3D Models in Monitoring Hydrotechnical Torrent Control Structures

Abstract

The usage of terrestrial photogrammetry is also known nowadays, in most of cases, as terrestrial scanner application. In this paper a stereo matching 3D algorithm is presented in order to use it in monitoring the torrent control structures. The present paper objective is to highlight the possibilities of terrestrial photogrammetry. In the studied case, a 3D model of a masonry dam has been extracted from several paired photos. The main conclusion of the study is that the methodology represents a future step in monitoring the hydrotechnical structures.
