Maintain actual real world scale of object within Agisoft?

[meshmaster]

Hello!

Is there some way to establish and/or maintain actual real-world scale of objects within Agisoft?

For example..

Currently I notice that if I do a scan of a head and then create an .obj from it Agisoft reports the size of the bounding box to be very small.  Of course I can choose other options, such as cm, inches, etc... but none of them seem to provide me with the actual equivalent size in "real world" units.

Is it possible for me to somehow establish the actual scale of an object in Agisoft?

What I'm getting at is that ideally I would like to scan an object that has an actual size of 24mm and have it spit out a model that also = 24mm.

Any advice you could offer would be most appreciated.

Cheers,

Joe

You have few options

1. use PRO version - set markers......
2. use checker board - create cube-plane with same dimension and set in externall 3D app
3. someone mentioned a way in Meshlab -

Hello,

yes, it is possible. You can measure points with the marking tool. First create two markers. Pin markers to a point in photo, you need at least 2 Fotos for each point. Be sure that you will recognize the points in the further images. Now if you have at least marked 2 points as described, there will appear in the modelview. now use the scale tool to "set reference scale". The known distance between these points will scale the whole model to the "real world" size.

I hope that was you question
