How can I know the transform from WGS to Local Coordinate

[rex]

Photoscan can export data both in Local coordinate and WGGS 84, but how can we know the exact transform matrix(or zero point if it is by ECEF coordinate ) between Local coordinate and WGS 84 in Photoscan

Hello rex,

The transformation between the internal coordinate system used (for unreferenced model) to geographic system is estimated when some reference points are used (like coordinates of the GCPs or camera positions).
