Multi-body Non-rigid Structure-from-Motion [PDF]
, 2016 Conventional structure-from-motion (SFM) research is primarily concerned with the 3D reconstruction of a single, rigidly moving object seen by a static camera, or a static and rigid scene observed by a moving camera --in both cases there are only one ...

SfM-Net: Learning of Structure and Motion from Video
CoRR, 2017 We propose SfM-Net, a geometry-aware neural network for motion estimation in videos that decomposes frame-to-frame pixel motion in terms of scene and object depth, camera motion and 3D object rotations and translations. Given a sequence of frames, SfM-Net predicts depth, segmentation, camera and rigid object motions, converts those into a dense frame ...

A Skeletal Camera Network for Close-range Images with a Data Driven Approach in Analyzing Stereo Configuration [PDF]
Journal of Geodesy and Geoinformation Science, 2022 Structure-from-Motion (SfM) techniques have been widely used for 3D geometry reconstruction from multi-view images. Nevertheless, the efficiency and quality of the reconstructed geometry depends on multiple factors, i.e., the base-height ratio ...

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 ...

Capturing complexity: field-testing the use of ‘structure from motion’ derived virtual models to replicate standard measures of reef physical structure [PDF]
PeerJ, 2019 Reef structural complexity provides important refuge habitat for a range of marine organisms, and is a useful indicator of the health and resilience of reefs as a whole.

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 ...

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 ...
