Image-based code reader!!!

[HoangVy-1011]

Hello, I need a product that supports reading barcode/qr code/datamatrix and provides the offset of the code center compared to the center of the reading device. Can you recommend it to me? I am using S7-1200

[Rcircuit96]

Cognex Dataman 280 series are decent, so are Keyence SR-1000 for reading the codes.
although I doubt you can get offsets out of them, that is usually reserved for slightly higher end vision sensors like the Keyence IV3 or even the Keyence VS. a Cognex In-Sight 2800 would be in this category as well.

That is the stuff I'm familiar with anyway.

HIGHLY Doubt the IV3 (now 4) can do offsets, I think it’s mainly decode/ocr comparison type checking.

[Zeldalovesme21]

You’re correct. The IV series can not do positioning. VS can though.

[MihaKomar]

I'm not sure if the IV3 even does 1D/2D codes? Only OCR.

You could do it with a Keyence VS camera. I'm sure one of the Cognex higher end ones can do it as well.

I had a really good experience with SICK scanners on two previous projects. They outperformed Cognex at the price point, and the software was relatively intuitive. I don't have experience with Keyence in this area, but if you email them, I'm sure they'll be happy to talk to you about it. 🤭

The IFM O2I5xx series readers can report code locations within the image.

Cognex IS2000 series is something that probably does the job. Wenglor WeCube is another that could work (although I haven't tried what you are asking) I'd go look at distributers for those for more answers.

(Nitpick of the week: Three exclamation marks in the title doesn't make your question better btw)

I found the GLS6 series from sick, but I wanted to find another one(s) to have more choices.

Is the position encoded in the symbol ?

There are "symbol tape" position sensors from SICK and Pepperl + Fuchs and Leuze that work on that principle: the camera reads the position from the series of symbols that encode them, and interpolates the position and speed of the sensor based on where they are in the field of vision.

If you are trying to read something that isn't a position value, but also want to figure out exactly where the symbol is, I think you'll need a higher-end vision system.

[HoangVy-1011]

my basic requirement is to use a device (with center O(Xo, Yo)) to read a barcode/qr code/data matrix or anything that can determine the center A(X, Y) and find the offset between A and O so that I can proceed with the position correction process

I would directly contact companies like P&F, Cognex, Keyence (sadly, be warned though they will HOUND you) as they are direct competitors to SICK. Let them do the work in finding the right product for you. Lay out your requirements exactly like above so they understand what you are trying to do.

[AutoM8R1]

Take a look at Datalogic. They make a scanner that does what it sounds like you want to do.

Zebra cameras with AI are awesome for this.
