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.
Claims3
Fixed optical equipment for acquiring optical information associated with at least an object placed on a supporting plane, comprising:
- a camera having a view cone and having an array of photosensing elements for acquiring an image of an acquisition zone on said supporting plane, and
- aiming means suitable to generate a luminous aiming figure extended in at least a first direction having a predetermined geometric relationship with said view cone of said camera.
Method of installation of a fixed optical equipment for acquiring optical information associated with at least an object placed on a supporting plane, said equipment comprising a camera having a view cone and an array of photosensing elements for acquiring an image of an acquisition zone on said supporting plane, and aiming means suitable for generating a luminous aiming figure extended along at least a first direction having a predetermined geometric relationship with said view cone of said camera, said method comprising the steps of:
- a) installing said camera in a first plane parallel to said supporting plane at a first predetermined height above said supporting plane;
- b) switching on said aiming means;
- and
- c) aligning said camera moving it in said first plane until said luminous aiming figure has a desired alignment with respect to said supporting plane.
Method for the diagnostic of an alignment of fixed optical equipment for acquiring optical information associated with at least an object placed on a supporting plane, said equipment comprising a camera having an array of photosensing elements for acquiring an image of an acquisition zone on said supporting plane, aiming means suitable for generating a luminous aiming figure extended along at least a first direction, and means for acquiring an image of said luminous aiming figure, comprising the steps of:
- a) installing said camera in such a way that said acquisition zone has a desired alignment with respect to said supporting plane;
- b) switching on said aiming means;
- c) acquiring an image of said luminous aiming figure;
- d) storing values of characteristic parameters of said acquired image;
- e) acquiring a second image of said luminous aiming figure;
- and
- f) checking whether values of said characteristic parameters of said second acquired image correspond with said values stored in said step d).
