DP-SfM: Dual-Pixel Structure-from-Motion without Scale Ambiguity
IEEE Transactions on Pattern Analysis and Machine IntelligenceMulti-view 3D reconstruction, namely, structure-from-motion followed by multi-view stereo, is a fundamental component of 3D computer vision. In general, multi-view 3D reconstruction suffers from an unknown scale ambiguity unless a reference object of known size is present in the scene.

Nanophotonics, Volume 15, Issue 20, 27 October 2026.The object beam and the reference beam interfere at the camera sensor surface and multi‐angle tomographic recording based on off‐axis digital holography. ABSTRACT Single‐frame fringe pattern analysis in digital holographic interferometry (DHI) is essential for precision phase measurement under dynamic conditions. Recent advances in deep learning within

Evaluation on the Accuracy of Structure From Motion（SfM）Photogrammetry on Gully Surveying
Shuitu baochi yanjiu, 2020 A typical gully was selected and measured using the tape method and structure from motion(SfM)photogrammetry in the village of Liangjianfang, Luanping County, Hebei Province. The accuracies of both gully surveying methods were evaluated via comparing the

DATAP-SfM: Dynamic-Aware Tracking Any Point for Robust Structure from Motion in the Wild
CoRRThis paper proposes a concise, elegant, and robust pipeline to estimate smooth camera trajectories and obtain dense point clouds for casual videos in the wild. Traditional frameworks, such as ParticleSfM~\cite{zhao2022particlesfm}, address this problem by sequentially computing the optical flow between adjacent frames to obtain point trajectories. They

Mechanisms for seeing transparency-from-motion and orientation-from-motion
, 2000 Structure-from-motion (SFM) perception is hypothesised to be mediated by units that sense the near-far relationships in transparency-from-motion (TFM) and orientation-from-motion (OFM).

Collinearity and Coplanarity Constraints for Structure from Motion
, 2006 Structure from motion (SfM) comprises techniques for estimating 3D structures from uncalibrated 2D image sequences. This work focuses on two contributions: Firstly, a stability analysis is performed and the error propagation of image noise is studied ...

EC-SfM: Efficient Covisibility-based Structure-from-Motion for Both Sequential and Unordered Images
, 2023 Structure-from-Motion is a technology used to obtain scene structure through image collection, which is a fundamental problem in computer vision. For unordered Internet images, SfM is very slow due to the lack of prior knowledge about image overlap.
