Evaluating the Performance of Structure from Motion Pipelines
Journal of Imaging, 2018 Structure from Motion (SfM) is a pipeline that allows three-dimensional reconstruction starting from a collection of images. A typical SfM pipeline comprises different processing steps each of which tackles a different problem in the reconstruction ...

An assessment of the accuracy of structure-from-motion (SfM) photogrammetry for 3D terrain mapping
Geomatics, Landmanagement and Landscape, 2020 Unmanned Aerial Vehicles (UAVs) equipped with photogrammetric or remote sensing instrumentations offer numerous opportunities in mapping and data collection for topographic modelling. An example is an emerging technique known as Structure-from-Motion (SfM) photogrammetry used for the collection of low-cost, high spatial resolution, three-dimensional ...

Mapping Glacier Ablation With a UAV in the North Cascades: A Structure-from-Motion Approach
Frontiers in Remote Sensing, 2022 The glaciers of the North Cascades have experienced mass loss and terminus retreat due to climate change. The meltwater from these glaciers provides a flux of cold glacier meltwater into the river systems, which supports salmon spawning during the late ...
