We're trying to set up a vision system to verify information between our routing sheets and the labels we're putting on our product. The routing sheets have 1D barcodes, and the labels have 2D labels.
I'm having issues with long 1D barcodes. We're trying to read 3 barcodes (type Code 39), so I'm setting up individual regions of interest for each barcode read, and this works fine for 2 of the 3 barcodes. One is significantly longer than the other two, 13 characters vs 7 or 4 characters, and I'm not getting it to read. I've attached snapshots of the barcodes below. The actual image quality seems good, and the print size of the different barcodes seems to be the same. (Vertical height is different, but that shouldn't matter, should it?)
Any suggestions for how to get this to read?
Reading the 2D matrices seems to work well.
Thanks for any ideas!
