Create 3D object from external camera view

Hello,

I have two pro cameras (optitrack) and I would like to create a 3D object from the main object that the camera views These camera work with tag to detect movment, and i would like that the 3D object created follow the movment of the real object

Any idea how to begin this project ? I've thought to get all the tag as point in space and to create a 3D object which connects all these point but if I do that, I'll lost a lot of information (texture of real object, details, depths,...) Thanks
