export_openMVS

This is a wonderful library.
The dense reconstruction is spectacular.
Thank you.

I want to geo-reference the project (with ground control points). I cannot build the ui_openMVG_control_points_registration from openMVG that feeds into your pipeline successfully.
To get around this; it's possible to do it after with SfM_georef or VisualSFM

I need to export the openMVS (scene_dense.mvs) project file.
Does InterfaceVisualSFM support this? - like: InterfaceVisualSFM scene_dense.mvs.

the geo-reference absolute position can be usually represented as a trasform from a local to an absolute coordinate space, ex from ENU to ECEF; all you need to do is reconstruct the SfM scene in ENU, compute the transoform to ECEF (OpenMVG should be able to do this), proceed with OpenMVS as usual in the ENU coordinate space, and at the end transform the mesh or the point cloud (whjatever you need) to ECEF, etc.

please do not use VisualSFM, it is deprecated and not performing as well

You are very kind to respond so promptly.

openMVG_main_geodesy_registration_to_gps_position can adjust a scene coordinate system to fit a GPS datum (typically from the photo centers).
What I need is ui_openMVG_control_points_registration to transform a scene with ground control (GCP).
I can't build the tool successfully and was hoping to export the openMVS dense_scene.mvs and transform with another library. Either SfM_georef or VisualSFM.

Can I export the dense_scene.mvs to another format?

[cdcseacave]

each openMVS step exports the computed data both in MVS and PLY format

Thank you.
