Title: What’s the standard encoding system for 12 bit code target in Photoscan?

What’s the standard encoding system for 12 bit code target in Photoscan?
I need to know how to read / identify that circular codes using python in other software for link the model side with I see in a film shot.

I suspect that codes have a standard library easy to read, but I don’t know how.

Any tip?

Hello Dinovfx,

Do you mean how the labels to the targets are assigned (i.e. the labeling convention)?

Hi Alexey

Not exactly.

What I need is detect and identify the same coded target used during the photogrammetry process, into others film or video shots of the same place / scene, into other software ( because Photoscan don't´ handle entire video shots ).

Suppose we have a beautiful castle or medieval wall making troungth Photoscan with many CT´s ,
and later, we film a medieval knight, in front of walls, walking and looking for a tower with the princess inside.
We need to associate the pointcloud with these cleare CT´s , and the CT´s that can we see in the background of the film shot ( to help the knight to find the princess in the right place )

 
So, I need to know what´s the coded system ( Schanider, RAD, or what ) and if exist a python compatible library or opencv method to read and identify that.

thanks in advance for any help.
