Journal ArticleDOI
Developments in monitoring and modelling small‐scale river bed topography
TL;DR: In this article, a detailed assessment of the distributed monitoring and terrain modelling of river bed topography using a technique that combines rigorous analytical photogrammetry with rapid ground survey is presented.
Journal ArticleDOI
Investigating the geomorphological potential of freely available and accessible structure-from-motion photogrammetry using a smartphone
TL;DR: Results for the river bank survey demonstrate that centimetre-precision DTMs can be achieved at close range (10 m or less), using a smartphone camera and a fully automated package, and improve to sub-centimetre precision with either higher-resolution images or by applying specific post-processing techniques to the smartphone DTMs.
Journal ArticleDOI
Accuracy of Unmanned Aerial Vehicle (UAV) and SfM Photogrammetry Survey as a Function of the Number and Location of Ground Control Points Used
TL;DR: This paper demonstrates how much the accuracy improves as the number of GCP points increases, as well as the importance of an even distribution, and how the ground sample distance of a project relates to the maximum accuracy that can be achieved.
Structure from motion (SFM) photogrammetry
TL;DR: In this paper, the basic concepts of SfM photogrammetry are presented, whilst recognising its heritage, and a few examples are employed to illustrate the potential of sfM applications for geomorphological research.
Journal ArticleDOI
Effective application of automated digital photogrammetry for geomorphological research
TL;DR: In this article, the role of photo-control, the significance of checkpoints in the object space, and the importance of camera calibration data are discussed, and an overview of self-calibration methods is provided, which is valuable in situations when a nonphotogrammetric camera has been used.
