Short communication: Challenges and applications of structure-from-motion photogrammetry in a physical model of a braided river [PDF]
Earth Surface Dynamics, 2019 For extending the applications of structure-from-motion (SfM) photogrammetry in river flumes, we present the main challenges and methods used to collect a large dataset (>1000 digital elevation models, DEMs) of high-quality topographic data using ...

Automated archiving of archaeological aerial images [PDF]
, 2016 The main purpose of any aerial photo archive is to allow quick access to images based on content and location. Therefore, next to a description of technical parameters and depicted content, georeferencing of every image is of vital importance.

A Low-Cost, Repeatable Method for 3D Particle Analysis with SfM Photogrammetry
Géosciences, 2023 The characterisation of particle shape is an important analysis in the field of sedimentary geology. At finer scales, it is key for understanding sediment transport while at coarser scales, such as boulders, it is vital for coastal protection.

Exploring the Optimal 4D-SfM Photogrammetric Models at Plot Scale
Remote Sensing, 2023 Structure from Motion (4D-SfM) photogrammetry can capture the changes in surface processes with high spatial and temporal resolution, which is widely used to quantify the dynamic change process of the ground surface.

Terrestrial SfM-MVS photogrammetry from smartphone sensors
Geomorphology, 2020 Smartphones can be regarded as cameras, natively equipped with geolocation and orientation sensors, making them powerful, portable, user-friendly and inexpensive tools for terrestrial structure from motion/multiview stereo photogrammetry (SfM-MVS) surveys. Camera extrinsic parameters (i.e.

Suitability of ground-based SfM-MVS for monitoring glacial and periglacial processes [PDF]
, 2016 Photo-based surface reconstruction is rapidly emerging as an alternative survey technique to lidar (light detection and ranging) in many fields of geoscience fostered by the recent development of computer vision algorithms such as structure from motion ...
