How to identify multiple QR codes in one image?

Hi,

I am wondering how can I identify multiple QR codes of 21x21 Matrix size, when each one of them has different information decoded. 

In the attached VI using the IMAQ read QR code I can Identify one QR code each time without issue but I cannot identify both the same time. Only if I hide one of two. The left one in the captured .png has data: 1_Left and the right has data: 2_Right.

The aim is to extract the bounding box of all the codes and overlay to the image.

Which is the best approach to do that? 

(In the IMAQ read barcode 2 you can set the number of barcodes to read but in QR code you cannot.)

Thanks

Harris
