OpenSfM: Open Source Structure From Motion Software
OpenSfM is an open source structure from motion software used to create 3D reconstructions from 2D images. It supports image sequences from diverse sources including internet photo collections, aerial surveys, and historical archives.
What is OpenSfM?
OpenSfM is an open source structure from motion software package for creating 3D reconstructions using 2D images. It works by estimating camera positions and geometries from overlapping images and using multi-view stereo methods to reconstruct dense 3D point clouds, meshes, and textured models.
Some key features of OpenSfM include:
- Supports image sequences from diverse sources including internet photo collections, aerial surveys, satellite imagery, and historical image archives
- Automated SfM pipeline for matching images, estimating camera poses, and building dense 3D models
- Bundler integration for efficient image matching using SIFT features
- CMVS/PMVS integration for multi-view sterero reconstruction
- Python APIs for accessing and processing reconstruction data
- Active development community with documentation and tutorials available
OpenSfM makes SfM techniques more accessible to researchers and developers needing 3D reconstructions from images. Its automated pipeline and open source nature provide flexibility for handling diverse image sets and integrating with other applications.
