## What it is
OpenMVS is an open-source C++ library for Multi-View Stereo 3D reconstruction, taking camera poses and a sparse point-cloud as input and producing a dense point-cloud, refined mesh, and textured mesh. It complements Structure-from-Motion pipelines like OpenMVG by covering the final stage of the photogrammetry workflow.

## Use cases
- reconstruct a dense 3D point cloud from a set of posed images
- generate a textured mesh from a sparse point cloud and camera poses
- refine a 3D mesh to recover fine surface details
- build the texturing stage of a photogrammetry pipeline
- pair with OpenMVG to go from photos to a full 3D model
- research in multi-view stereo and stereo matching algorithms

## When to choose
- you already have camera poses and a sparse point cloud from SfM and need dense reconstruction
- you need an open-source, scriptable MVS pipeline with CLI tools
- you want full control over dense point cloud, meshing, refinement, and texturing stages
- you are doing computer-vision research on multi-view stereo

## When to avoid
- you need an end-to-end photo-to-model tool with a GUI
- you only have raw images without camera poses or a sparse point cloud
- you need a permissively licensed library (it is AGPL-3.0)
- you want real-time or lightweight 3D scanning on mobile hardware
