UnitV Barcode scanning

[puijkh]

Hi, I am trying to scan a barcode with my UnitV, but i was not successfull.
I am using the MaixPy IDE have uodated to the latest fw and use this code:

img = sensor.snapshot()
res = img.find_barcodes()

Unfortunately there is never any info in the returned res. I can see the barcode in the MaixPy IDE. I also tried qr codes with res = img.find_qrcodes(), but that also does not work.

Any idea's on how to get the scanning working?

@puijkh Same for me with april tags. Did you found a solution?

Hi, Maybe flipping the sensor image will fix this:

sensor.set_vflip(1)

This was the solution for my problem with april tags and QR-Codes.
