U-Type Algorithm - 1D Barcode

191

h. Image Plane

• Select the one that having best contrast among the Polarity Marking and

background.

i. Invert

• Used to invert the greyscale of the barcode from dark to bright and vise

versa.

j. Threshold Mode

❖ Fixed - Used when Barcode and background having good contrast.

❖ Dynamic - Used when Barcode and background having low contrast.

k. Threshold Count

• Threshold count is used to inspect the barcode with a constant inspection

range which threshold count is 17 as default value.

• When threshold count set to 17, the barcode will be decoded for 17 times

in a range of different grayscale level.

I. Median Filter

• This setting is use to remove the white dots (Noise)

m. Encoding Type

• Encoding Type is the barcode formats that able to support.

• Supported Encoding type as below:

❖ Codebar

❖ Code 39

❖ Code 93

❖ Code 128

❖ EAN 8

❖ EAN 132/5 Industrial

❖ 2/5 Interleaved

❖ All

n. Zoom Factor

• Zoom factor is used to set the inspection size of the barcode.

• When Zoom factor set to 0.5 (50% of original barcode size)

U-Type Algorithm - 2D Barcode

a. Barcode Format

• The barcode formats that able to support are show below:

b. Scale X & Scale Y

• Scale X and Scale Y used to set the inspection size of the barcode. There

have the range of 0.1 to 1.0 which covered 10% of orignal barcode size to

100% of original barcode size.

• Scale X is the vertical direction while scale Y is the horizontal direction.

• When scale X and scale Y set to 0.5, the barcode after rescale will display

at center of barcode inspection box. (red)
