Location of barcodes in image

We would like to use RoboRealm to read all barcodes in a stack of cartons as part of a factory automation system.  We did a quick trial using the barcode module and it successfully read multiple (>10) barcodes simultaneously. However, to determine if there is a defective label, we also require the location the [correctly read] barcodes in the image. Please could you make the centroid or bounding box coordinates of the barcodes accessible through Geometric Statistics?

David,

For 2D barcodes see the updated documentation for DataMatrix and QR Codes. There are variable that get set when a barcode is detected with X,Y information that you would get from the Geo Stats module.

If you are using 1D barcodes let us know.

Thanks for your prompt reply. All the barcodes we work with are 1D -- it's the industry standard for labeling cartons.

David,

The system was just updated to include X, Y coordinates for 1D barcodes. See the documentation page for more information and download the latest version.

Note, only the center X,Y coordinates for 1D barcodes are provided instead of the full barcode area. Hopefully this is sufficient for your needs. If not, it may be possible to use other filters like thresholding, dilation, etc. to detect the full areas. If you need additional help, please include a sample image so we can ensure we understand what you are working with.

Thanks,
STeven.

Hi STeven, the center coordinates are fine since the barcodes adhere to a standard format  and their orientation is generally horizontal. I'll test the new release next week. Many thanks for adding this feature!
