Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

CLAIMS

1. A machinery for scanning a slab (4) of rock material, comprising:

a support (2) to support the slab (4) ,

a scanner (6) configured to capture an image of the slab (4) ,

a reader device configured to read an identifying element (8) , in particular containing items of information, applied on the slab (4) ,

a control unit adapted to produce, as an output, an image of the slab (4) ; wherein the control unit is configured to receive from the reader device an input signal concerning the identifying element (8) and, based on said input signal, to determine the parameters with which the scanner (6) scans the slab (4) and/or the parameters with which the control unit processes the output image of the slab (4) .

2. Machinery according to claim 1, wherein the identifying element (8) is a barcode or a QR code and the reader device is adapted to read said barcode or QR code.

3. Machinery according to claim 1 or 2, wherein the parameters with which scanner (6) is adapted to capture the image of the slab (4) include at least one between: intensity of a light beam emitted by a light source belonging to the scanner (6) , frequency of the light beam.

4. Machinery according to any one of the preceding claims, wherein on the support (2) there are applied first optical references (10) configured to be detected by the scanner (6) ;

wherein the control unit, based on this detection, is configured to carry out a correction of the output image of the slab (4) .

5. Machinery according to any one of the preceding claims, wherein the scanner (6) is adapted to detect second optical references (12) applied on the slab (4) ; and the control unit is configured to determine the position of these second optical references (12) and, based on this position, to produce, as an output, the spatial positioning of the slab (4) with reference to the reference system.

6. Machinery according to any one of the preceding claims, wherein the scanner (6) is mobile relative to the support (2) .

7. A process for scanning a slab (4) of rock material, comprising the steps of:

providing a machinery according to any one of the preceding claims,

applying (100) on the slab (4) an identifying element (8) , in particular containing items of information, ,

placing (102) the slab (4) on the support (2) ,

reading (104) the identifying element (8) and, based on said reading, determining (106) the parameters with which the scanner (6) scans the slab (4) and/or the parameters with which the control unit processes the output image of the slab (4) ,

capturing (108) an image of the slab (4) through the scanner (6) ,

producing (110) , as an output, an image of the slab

(4) .

8. Process according to claim 7, comprising the steps of: detecting second optical references (12) applied on the slab (4) ;

determining the position of these second optical references (12) and, based on this position, producing, as an output, a spatial positioning of the slab (4) in a reference system.

9. Process according to claim 7 or 8, comprising the steps of :

detecting first optical references (10) applied on the support (2) ;

- based on this detection, carrying out a correction of the output image of the slab (4) .

10. Process to produce an article made of a rock material, comprising the steps of:

obtaining the spatial positioning of the slab (4) in the reference system, carrying out the process according to claim 8,

defining a cutting outline in said reference system along which to carry out the cutting of the slab (4) ,

cutting the slab (4) based on the cutting outline.

11. A computer program containing instructions to have the machinery carry out the process according to claims 7, 8 or 9 according to any one of the claims from 1 to 6.

12. Computer program containing instructions to have a cutting machine to cut the slab (4) carry out the process according to claim 10.
