Barcode can not detect barcode in an image

I run the (sample) barcode.exe in OpenCV 4.90 32bit, Windows 11, for the image attached, there is no detection result.

afaik, it can only read variants of ean/upc code, – and this is something else.

cognex says that is “code 128”.

I haven’t found the docs mention what’s supported.

you could file an issue on opencv’s github and request improvement to the documentation
