SfM with MRFs: Discrete-Continuous Optimization for Large-Scale Structure from Motion [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2013 Recent work in structure from motion (SfM) has built 3D models from large collections of images downloaded from the Internet. Many approaches to this problem use incremental algorithms that solve progressively larger bundle adjustment problems. These incremental techniques scale poorly as the image collection grows, and can suffer from drift or local ...

Structure-from-Motion (SfM) monitoring of nourished gravel beaches in Croatia
Coasts, Marine Structures and Breakwaters 2017, 2018Beach nourishment is now widely used as a “soft” coastal protection but its performance is still relatively poorly understood. Beach monitoring allows performance analysis over a range of environmental conditions which, in turn, can provide the basis for successful nourishment design and implementation. Remote sensing techniques based on Structure-from-

Approximate Volume of Sand Materials Stockpile Based on Structure From Motion (SFM)
2020 6th Information Technology International Seminar (ITIS), 2020Information can be obtained through image processing. One of the information that can be obtained is the Volume of a 3-dimensional object. A digital image is 2dimensional data obtained from shooting an object using a camera. A stockpile is a place to store material in an open area.

Three-Dimension Measurement of Mechanical Parts Based on Structure from Motion(SfM) Algorithm
Recent Advances in Computer Science and Communications, 2021Background: As an important branch of computer vision, visual measurement is a fast developing cutting-edge technology, which has been widely used in the manufacturing field. In recent years, the visual measurement of feature size of probes through small IC probes has aroused wide concern. Objective: This study aims to take small shaft parts as the

Dense-SfM: Structure from Motion with Dense Consistent Matching
2025 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)We present Dense-SfM, a novel Structure from Motion (SfM) framework designed for dense and accurate 3D reconstruction from multi-view images. Sparse keypoint matching, which traditional SfM methods often rely on, limits both accuracy and point density, especially in texture-less areas.

Adequate knowledge of geological structure is an essential for most studies in geoscience, mineral exploration, geo-hazard and disaster management. The geological map is still one the datasets the most commonly used to obtain information about the geological structure such as fault, joint, fold, and unconformities, however in rural areas such as ...

This work presents the workflow used to obtain spatial information to analyze geomorphological changes in the upper reach of the Cinca River (Southern Pyrenees) during the 1927-2015 period. The final products after application of the SfM-MVS methodology are orthomosaics with a root mean square error (RMSE) of 0.5-1 m, and point clouds with an RMSE of 1-
