COLMAP is a general-purpose Structure-from-Motion (SfM) and Multi-View Stereo (MVS) pipeline for reconstructing 3D models from ordered or unordered image collections. It provides both a graphical interface and a command-line interface, plus Python bindings (PyCOLMAP), and is written in C++.

Use cases

• reconstruct 3D models from a set of photos
• estimate camera poses from unordered image collections
• generate dense point clouds and meshes with multi-view stereo
• run incremental structure-from-motion pipelines from the command line
• use Python bindings to script 3D reconstruction workflows
• prepare camera poses and sparse point clouds for Gaussian splatting or NeRF
• support multi-camera rigs and various camera models in reconstruction

When to choose

• you need a robust, battle-tested SfM/MVS pipeline with both GUI and CLI
• you want to reconstruct 3D scenes from photos without writing your own algorithms
• you need Python bindings to integrate reconstruction into ML pipelines
• you require support for many camera models and multi-camera rigs

When to avoid

• you need real-time SLAM on video streams rather than offline reconstruction
• you want a lightweight library for a single geometric operation only
• you need a fully automated cloud service rather than self-hosted software
• your project requires a permissive license and the BSD terms here are unacceptable
