Agisoft Metashape vs COLMAP

Agisoft Metashape processes digital images into 3D spatial data for GIS, cultural heritage documentation, visual effects, and indirect measurement. It works with aerial, close-range, and satellite imagery, including automatic camera calibration and multi-camera projects. Professional Edition can create and edit terrain and surface models, georeferenced orthomosaics, and EPSG-based outputs. Its surveying functions include aerial LiDAR point attributes, laser scan registration, ground control points, targets, and scale bars. It also handles RGB, NIR, thermal, multispectral, and satellite imagery, and can calculate user-defined indices such as NDVI. Professional Edition adds Python scripting, Java bindings, distributed calculations on a local network, and a cloud processing interface. Standard and Professional installers are available for Windows, macOS, and Linux. A 30-day full-function trial is available; demo mode blocks saving and exporting. Standard Edition costs $179, paid once, and Professional Edition costs $3,499, paid once. Regular licenses are not time-limited and include 12 months of email technical support and free updates through version 2.x.x.

COLMAP is a free pipeline for reconstructing scenes in 3D from ordered or unordered image collections. Its Structure-from-Motion stage estimates camera poses and sparse 3D structure; its Multi-View Stereo stage uses PatchMatch stereo and stereo fusion to produce dense point clouds and meshes. Users can work through a graphical interface or command line. The GUI’s automatic reconstruction tool accepts an image folder and creates sparse and dense results in a workspace folder. For development, PyCOLMAP offers Python bindings for most functionality, and COLMAP can be built as a library for C++ code. Feature extraction options include SIFT, ALIKED, and LoMa; ALIKED and LoMa require ONNX support at build time. It supports a range of camera models and multi-camera rigs. Users can install pre-built binaries or build from source; macOS users also have a Homebrew formula, and a pre-built Docker image includes CUDA support. The library uses the new BSD license, while third-party dependencies have separate licenses. The project describes COLMAP as research software that may occasionally exit ungracefully when constraints are not met.
