GLOMAP is a global structure-from-motion pipeline for image-based 3D reconstruction that takes a COLMAP database as input and outputs a COLMAP sparse reconstruction. It is significantly faster than COLMAP's incremental mapper (typically 1-2 orders of magnitude) with on-par or superior quality, but is now deprecated and merged into COLMAP as its 'global' mapper.

Use cases

• reconstruct 3D scenes from image collections
• run global structure-from-motion on a COLMAP database
• speed up sparse 3D reconstruction compared to COLMAP incremental mapping
• average rotations and estimate camera positions globally
• produce COLMAP-compatible sparse reconstructions
• reconstruct large-scale photo datasets efficiently

When to choose

• you need fast, scalable sparse 3D reconstruction from images
• you already have a COLMAP database with features and matches
• you want COLMAP-compatible output with better runtime

When to avoid

• starting new projects - use COLMAP's built-in global mapper instead
• you need maintained software with active support
• you need dense reconstruction rather than sparse
