Revision history [back]

Hi,

The position of the joint head is the "position" field. The orientation gives the orientation of the coordinate frame associated with the point. It means that for example I turn my head to the right, the orientation will change, but the position will remain the same.

In order to only take the x,y coordinate, you have to project the 3D data into a 2D. You can find the projection matrix of the kinect on the internet, see this topic for more information...

Have a good day,

Bests,

Stéphane
