Here we want to show you how to add measurements to a 3 D model.
The markers we add to the model will also show up in the Photos. It may be more accurate to add the markers to the photos and not to the model.
For this you need the professional edition of Agisoft Photoscan.
I am Gabriel. Jon, Charlie, Hugh, Corey and I use photogrammetry to make 3 D models of fossils. We try to demonstrate in a few tutorials how to use Photoscan from Agisoft. We learend how to use Agisoft Photoscan at the SVP meeting in LA in 2013, they were taught by Neffra Matthews and Brent Breithaupt.

- Rename the marker
Ctrl Click the two which go together
- Create Scale Bar
- View Source
Add distance in m
Put in two new markers
Make scale bar

and you will have to re-center the 3D model
View Estimate gives you the distance
View Source: can put in more measurements
That's it for today. Let us know what you think.
