Following this tutorial: QR codes in Unreal - Mixed Reality | Microsoft Learn, I was able to see the HoloLens 2 tracking a QR code. However, if there are more than 1 QR code in the view, it only tracks one of them. Is there a way to track multiple QR codes at the same time?
So the problem was that the QR codes I was tracking all had the same pattern. It worked when I tried tracking 2 QR codes simultaneously with unique patterns!
The experiment shows that hololens2 will track two QRcodes when two different QRcodes appear in the screen at the same time. But I couldn’t figure out how to detect different QRcodes in the UNREAL ENGINE blueprint. I tried to compare the text to the GUID but failed. Hope to get help
