An augmented reality system (10) arranged to superimpose, in front of a user, a virtual light field of a 3D content to the real light field of a surrounding environment. The system (10) provides an augmented reality display (100) comprising a light field display (110) arranged to create a virtual light field of the 3D content, and a beam combiner (130) arranged to deviate the light rays emitted by the virtual light field of the 3D content and project them in front of a user in order to overlap the virtual light field of the 3D content to the real light field of the surrounding environment. Furthermore, the augmented reality display (100) is adapted to be worn by the user on its own head. The augmented reality system (10) also comprises a tracking system (140) arranged to real time monitor position and orientation of a moving reference system S 1 integral to the augmented reality display (100) with respect to a fixed reference system S 2 integral to surrounding environment. The system (10) comprises then a control unit (150) arranged to receive from the tracking system (140) an information about position and orientation of the moving reference system S 1 and to determine the virtual light field of the 3D content coherent with position and orientation of the moving reference system S 1 with respect to the fixed reference system S 2 .

Abstract
An augmented reality system (10) arranged to superimpose, in front of a user, a virtual light field of a 3D content to the real light field of a surrounding environment. The system (10) provides an augmented reality display (100) comprising a light field display (110) arranged to create a virtual light field of the 3D content, and a beam combiner (130) arranged to deviate the light rays emitted by the virtual light field of the 3D content and project them in front of a user in order to overlap the virtual light field of the 3D content to the real light field of the surrounding environment. Furthermore, the augmented reality display (100) is adapted to be worn by the user on its own head. The augmented reality system (10) also comprises a tracking system (140) arranged to real time monitor position and orientation of a moving reference system S 1 integral to the augmented reality display (100) with respect to a fixed reference system S 2 integral to surrounding environment. The system (10) comprises then a control unit (150) arranged to receive from the tracking system (140) an information about position and orientation of the moving reference system S 1 and to determine the virtual light field of the 3D content coherent with position and orientation of the moving reference system S 1 with respect to the fixed reference system S 2 .I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
