5. Vertical Alignment and Horizontal Stitching
5.1 Principle of Stitching
See Fig. 5-1 Principle of Stitching, page 131.
The following description refers to Stitching of Camera A and Camera B, but it applies for
other adjacent cameras as well.
As shown in the Scanner Block Diagrams in Section 2.2 the fields of vision of adjacent
cameras overlap.
The Stitching Wire is placed within the ‘overlapped’ area and is seen by both CCD-Cameras.
The scanned image of the Stitching Wire is used to determine the virtual end point of
Scanline A and the virtual start point of Scanline B.
The pixel stream from Camera A is stopped N
A
pixels before the image of the Stitching Wire,
and the pixel stream from Camera B is started N
B
pixels after the image of the Stitching Wire.
As illustrated by Fig. 5-1, page 131, the Stitching depends on the distance between the
Stitching Wire and the Original as well as on the size of N
A
and N
B
.
Whenever the scanner is idle, the Stitching is continuously updated and corrected for relative
changes in the position of the Stitching Wire parallel to the glass plate. If the position of the
Stitching Wire is changed perpendicular to the glass plate, the Stitch values, which are stored
in Flash Memory on the SUC-Board, must be corrected using SCANtest 6, Test 11 or Scanner
Maintenance.
The mounting of the Stitching Wire is shown in Fig. 5-2, page 132.
