Bridging Open-Source Photogrammetry : Toward Synergies Between Meshroom, MicMac and others

Résumé

Abstract. This paper introduces MicMacRoom, a prototype that bridges the qualitative photogrammetric workflow of MicMac with the intuitive, node-based interface of Meshroom, addressing critical limitations of open-source photogrammetry in usability, interoperability, and sustainability. Developed by a working group of the French National 3D Consortium, MicMacRoom targets Cultural Heritage applications by providing customizable workflows for key processes ; dense cloud generation, meshing, and orthophoto production. As an open-source project, MicMacRoom provides public access to its source code, documentation, and processing templates, laying the foundation for a unified and sustainable photogrammetry ecosystem. The current version of the prototype is a starting point for future developments, focusing on expanding interoperability with additional image-based modeling tools and methods. This article also presents the ongoing integration of colour calibration as a preliminary step for ensuring future compatibility with advanced multi-view photometric workflows.
