Abstract: A fixed optical equipment for acquiring optical information associated with at least an object placed on a supporting plane is described, comprising a camera (10) having an array of photosensing elements (11) for acquiring an image of an acquisition zone on the supporting plane, characterized by comprising aiming means (30) suitable for generating a luminous aiming figure extended in at least a first direction having a predetermined geometric relationship with the view cone of the camera (10). Methods for its installation and for the diagnostic of its alignment are also described.

Abstract: For measuring the volume, the process utilizes the same means as are used for reading an optical code, such as a laser scanner or CCD reader. A choice of different measuring procedures are proposed which suit different situations and are all based on scannings and readings performed on the object. Where required, the process can accommodate the inclination angles of the scan planes. The volume measurement is accompanied by the reading of an optical code provided on the object.
