I’m trying to detect multiple QR codes in a single image.
I’m using VL.OpenCV, and QRCodeDetector but it seems like it’s only capable of detecting one QR code at the time, as it only outputs a String, not a Spread.
I looked inside the QRCodeDetector, and saw that it’s using DetectAndDecode() method. From OpenCV documentation, there is another method called DetectAndDecodeMulti(). But this one doesn’t seem to be part of VL.OpenCV yet.
I could find DetectMulti() and DecodeMulti() in VL.OpenCV but I didn’t managed to use them: I constantly get the error
points.size().width > 0 with DecodeMulti().
Did someone already find a way to detect multiple QR codes in a image with QRCodeDetector, or other method?
