Abstract
A sensing head for providing bi-dimensional and tri-dimensional data determinative of a position and an orientation of a target object is provided. The sensing head combines both a bi-dimensional and a tri-dimensional sensors. General illumination is associated to the bi-dimensional sensor to allow the acquisition of bi-dimensional data representative of the target object. A stripe-shaped laser light output is projected and diffused on the target object and is sensed by the tri-dimensional sensor. Tri-dimensional data is thus acquired. By proper processing of the bi-dimensional and tri-dimensional data, the position and orientation of the target object may be determined without moving the sensor head and without knowing its position and orientation.
