Light3R-SfM: Towards Feed-forward Structure-from-Motion [PDF]
2025 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)We present Light3R-SfM, a feed-forward, end-to-end learnable framework for efficient large-scale Structure-from-Motion (SfM) from unconstrained image collections. Unlike existing SfM solutions that rely on costly matching and global optimization to achieve accurate 3D reconstructions, Light3R-SfM addresses this limitation through a novel latent global ...

An assessment of the accuracy of structure-from-motion (SfM) photogrammetry for 3D terrain mapping [PDF]
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 ...

On-Barn Pig Weight Estimation Based on Body Measurements by Structure-from-Motion (SfM). [PDF]
Sensors (Basel), 2018 Information on the body shape of pigs is a key indicator to monitor their performance and health and to control or predict their market weight. Manual measurements are among the most common ways to obtain an indication of animal growth. However, this approach is laborious and difficult, and it may be stressful for both the pigs and the stockman.

Multistage SFM: Revisiting Incremental Structure from Motion [PDF]
2014 2nd International Conference on 3D Vision, 2014 In this paper, we present a new multistage approach for SfM reconstruction of a single component. Our method begins with building a coarse 3D reconstruction using high-scale features of given images. This step uses only a fraction of features and is fast.

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 ...
