Hi Zahkay,

 

Have you tried reading other barcodes? 

 

Make sure you have the right and consistent lighting, after this you can look into enhancing the image by applying grayscale filters or morphology as pre-processing steps for the 1D barcode reading. If you are new to image processing applications I would suggest reviewing the following tutorials:

 

Image acquisition system setup

Grayscale filters

Morphology Operations

http://zone.ni.com/reference/en-XX/help/372916P-01/nivisionconcepts/primary_morphology_operations/

 

There is also an example within LabVIEW that you can use as reference for your application when you install the Vision Development module toolkit.

Hello,

I would like to return to the topic of the initial question about the reader of the barcode reader. You have exchanged several models but all of them are rather branded. I would like to spend a bit less and I wonder if you could deal with a bar code reader of an unknown company. I'm thinking about barcode scanner HDWR but I'm afraid it will not work. It is not Chinese. I'm lokking for a ebay. Have you used some of the cheaper readers of an unknown brand?
