Rotation Free Active Vision [PDF]
, 2015 International audience— Incremental Structure from Motion (SfM) algorithms require, in general, precise knowledge of the camera linear and angular velocities in the camera frame for estimating the 3D structure of the scene.

Light3R-SfM: Towards Feed-forward Structure-from-Motion
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 ...

Quantifying the Influence of Surface Texture and Shape on Structure from Motion 3D Reconstructions
Sensors, 2022 In general, optical methods for geometrical measurements are influenced by the surface properties of the examined object. In Structure from Motion (SfM), local variations in surface color or topography are necessary for detecting feature points for point-

Identifying mechanisms of shore platform erosion using Structure‐from‐Motion (SfM) photogrammetry [PDF]
Earth Surface Processes and Landforms, 2019 AbstractShore platforms control wave energy transformation which, in turn, controls energy delivery to the cliff toe and nearshore sediment transport. Insight into shore platform erosion rates has conventionally been constrained at millimetre‐scales using micro‐erosion metres, and at metre‐scales using cartographic data.

Mapping Wild Leek through the Forest Canopy Using a UAV
Remote Sensing, 2018 Wild leek, an endangered plant species of Eastern North America, grows on forest floors and greens up to approximately three weeks before the trees it is typically found under, temporarily allowing it to be observed through the canopy by remote sensing ...

Quantifying Tufa Growth Rates (TGRs) using Structure-from-Motion (SfM) Photogrammetry
Proceedings of the 6th International Conference on Geographical Information Systems Theory, Applications and Management, 2020 The production of high-quality digital surface models (DSMs) is an increasing interest throughout the various geomorphometry studies. Consequently, a wide range of advanced geospatial methods has been used at different scales. Despite the fact that Structure-from-Motion (SfM) photogrammetry is one of the most popular methods until now it has not been ...

A factorization approach to inertial affine structure from motion [PDF]
, 2016 We consider the problem of reconstructing a 3-D scene from a moving camera with high frame rate using the affine projection model. This problem is traditionally known as Affine Structure from Motion (Affine SfM), and can be solved using an elegant low ...

Active Structure from Motion for Spherical and Cylindrical Targets [PDF]
, 2014 International audienceStructure estimation from motion (SfM) is a classical and well-studied problem in computer and robot vision, and many solutions have been proposed to treat it as a recursive filtering/estimation task.
