Abstract
A method of determining a position and orientation of a device is provided. The position and orientation of the device is determined based on multiple degrees of freedom (DoF) and the device is associated with a capturing device for capturing at least one image is provided. The method includes: capturing at least one image of a real object with the capturing device, and providing a coordinate system in relation to the object; providing an estimation of intrinsic parameters of the capturing device; providing pose data to compute first and second DoFs in the coordinate system, with each DoF having a confidence degree; determining an initial pose of the device; performing a pose estimation process, and calculating in the pose estimation process an estimation of the DoFs having a second confidence degree; and determining a position and orientation of the device.
