What is the OPF?

OPF stands for ‘open photogrammetry format’ - a new standard in photogrammetry, aimed at exchange and collaboration.

OPF is a specification for a flexible and extensible format that stores all of the data related to a reconstructed 3D model made with photogrammetry. It is an open, standardized, and free file format.

Who can benefit and how?


OPFs can be used to showcase the in-depth structure of modern photogrammetric projects and enable tweaking of the various assets generated.


Enable the building of new technology based on photogrammetry outputs with OPF, or develop new photogrammetry algorithms that can easily be used by others.


Third-party users can develop their own techniques for tailoring OPF to add new shareability functions.
