Method and arrangement for 3-dimensional image model adaptation

A method for adapting a 3D model of an object, comprising the steps of:

• performing at least one projection of the 3D model to obtain at least one 2D image model
• projection with associated depth information;
• performing at least one state extraction operation on the at least one 2D image model projection to obtain at least one state comprising a configuration of object features;
• determining a target state using the at least one state and external state information;
• adapting the at least one 2D image model projection and the associated depth information using the at least one state and the target state to obtain at least one adapted 2D image model and an associated adapted depth;
• and
• back-projecting the at least one adapted 2D image model to 3D based on the associated adapted depth to obtain an adapted 3D model.

An apparatus configured to perform a method comprising the steps of:

• determining a target state using the at least one state and external state information;
• adapting the at least one 2D image model projection and the associated depth information using the at least one state and the target state to obtain at least one adapted 2D image model and an associated adapted depth;
• and
• back-projecting the at least one adapted 2D image model to 3D based on the associated adapted depth to obtain an adapted 3D model.
