Does anyone know whether the Rotations X,Y and Z reported for the photos are the photogrammetric Omega, Phi and Kappa or Azimuth, Swing and Tilt. I am wanting to write a script or Excel spreadsheet to calculate Photosynth model space coordinates for control points measured in image pairs.

Cesar Lopez and Kean Walmsley are two others that come to mind as well.

Photosynth developer "douglas" may also be able to help you, since he spoke up in this previous discussion:
