Device and method to reconstruct in 3d the surface of a complete loop around a subject

A device to achieve 3D reconstruction of a surface of a 360° loop of an object or a body (30), comprising:

• at least one passive stereovision camera 3D equipped with a double optics (10), and
• a turn table (10) which is carrying the object or body to be imaged (30) or, alternatively, a rotating frame (21) carrying the at least one 3D camera (10) and rotating around the object or body to be imaged (30), configured such that the object or body (30) is within the field of view of the at least one 3D camera (10), and
• a control mean (40) that manage the rotation of the turn table (20) or, respectively, a control mean (41) that manage the rotation of the rotating frame (41), and
• a control mean (50) for remote triggering of the at least one 3D camera (10) and for acquiring stereo pairs of images according to viewing angles covering a 360° loop around the object or body (30), and
• computation means (60) for the 3D reconstruction of 3D surfaces from the acquired stereo pairs of images, and
• computation means (80) for the stitching in 3D of the acquired 3D surfaces into a comprehensive 3D representation of a complete 360° loop of the surface of the imaged object or body (30).
