The SABA 3000 XCR software for X-ray Character Recognition acts as an additional

module within the SABA 3000 image evaluation system. It is designed for automatic

numeric character recognition.

The cast-on clear text information (e.g. mould numbers) is read from

the X-ray radioscopic image.

• Produced under ISO 9001 certified quality management system.

Application

Technical Data

Font ISO Standard Type in accordance with DIN 6776 B vertical, with the following deviation:

Space between numeric characters = three times the line width, user scalable,

starting from 10 mm height at 100 µm/pixel.

Font sample:

Allowable numeric characters: 0, 1, 2, 3, 4, 5, 6, 7, 8 ,9

Minimum values of numeric characters, based on an image resolution of 100 µm/pixel

and an X-ray tube current of 4 mA:

Height (nominal size) 10 mm

Width (at nominal size) 5 mm, the numeric character 1 having a 3 mm width

Line width 1 mm, (-0.1 mm, +0.4 mm)

Minimum distance between numeric characters 3 mm

Required type elevation (minimum values) with given material thickness

Material thickness [mm] 5 10 20 30

Type elevation [mm] 0.75 1 1.6 >2.4

Numeric character slant approximately 3°

Numeric character arrangement in the image rectangular relative to the image border (0°, 90°, 180°, 270°)

Deviation of the character string position from the nominal position ± 2 mm

Deviation of the rotation (within the string) from the nominal position ± 2 °

Xray GE Inspection Technologies Description In order to obtain accurate character recognition results the following prerequisites have to be met: • • • • The font to be used is the ISO Standard Type for drawings in accordance with DIN 6776 B vertical. This type is characterized by high legibility. Each individual numeric character must be distinct in shape to prevent confusion with others. • The distance between two numeric characters must be three times the line width (d).
