MicMac

MicMac is a computer vision library that provides a comprehensive set of tools for 3D reconstruction and computer graphics. Developed by the French National Institute of Geographic and”:”Forestry Information (IGN), it is designed for researchers and professionals working with imagery and sensor data. The library is open-source and available under the Apache 2.0 license, encouraging widespread adoption and community contribution.

The core functionality of MicMac revolves around photogrammetry and multi-view stereo. It can process various types of image data, including aerial photographs, satellite imagery, and terrestrial scans. Key features include camera calibration, image orientation, dense point cloud generation, and meshing. MicMac is particularly known for its robust handling of large datasets and its ability to produce high-accuracy 3D models.

MicMac supports a wide range of input formats and integrates with other geospatial software. Its command-line interface makes it suitable for batch processing and integration into automated workflows. While it can be complex to learn, its power and flexibility make it a valuable tool for applications such as digital elevation model creation, urban planning, cultural heritage preservation, and scientific research. The project actively maintains documentation and provides a platform for users to seek support and share knowledge.
