Barcode Tracking

[Flo93]

Hi everyone,

i've built a program to inspect electrical contacts, which runs fine. Now i would like to add a barcode reader, to automatically change the inspection programm.

For inspection i use a 12 megapixel camera, with a telecentric objectiv. The field of view is just 20 x20 mm. The barcode i would like to "scan" are about 40mm in length.

Is it possible to generate the barcode out of more images? I think about slowly shifting the barcode under the camera with object tracking.

Is there an easy way to deal with it? Because if it's difficult and needs a lot of time i will just buy a simple handheld barcode reader.

Have you tried the function 'IMAQ Read Barcode"?

There's are a few examples in the Example Finder under Toolkits and Modules -> Vision -> Barcodes. One of those examples might be close to what you're looking for and would be a good starting point.

Thank you very much. It seems to be difficult to track the Barcode within different Images, so I am going to buy a handheld Barcode Reader.

Hello

Try combining multiple images to one using any of the following methods

1. Convert Image to Array and append the images

2. Use IMAQ ImagetoImage.vi

Then you can use the barcode VI and try. Please attach one set of barcode images so that we can get an idea how it looks like.

Hope this helps
