COLMAP is an open-source tool built for 3D reconstruction and computer vision research. It provides pipelines for Structure-from-Motion (SfM) and Multi-View Stereo (MVS), enabling automated feature extraction, matching, and 3D model generation. COLMAP runs via CLI, making it lightweight and easy to use for research, experimentation, and production workflows.

Features of COLMAP:

• Complete pipeline for 3D reconstruction from images.
• Command-line interface for fast and efficient usage.
• Supports CPU and GPU computation for large-scale reconstructions.
• Feature extraction, matching, and bundle adjustment tools.
• Works with multiple datasets and image formats.
• Open-source and extensible for custom computer vision projects.
• Widely used in research, robotics, AR/VR, and graphics applications.
