Hi,
This is one of the core project of my faculty, I mean defining a quality standard for heritage documentation using low budget system.

You can try two different systems:
-   Setting cross section by coordinates as poly, export vertex coordinates, and compare them.
-   Mesure targets into your model with GPS or total statation and compare the 3D face vertex coordinate with the survey data

In order to make it work you have to project your survey and calculate pixel size.


Good luck!
