QR Code Read

Postby marcus007 » Wed Sep 13, 2017 3:23 am

Hi
I have recently bought a OpenMV M7 & I Want to Decode QR Code with this Cam.
At small distance I am able to decode it but if I want to decode it at far distance like 5-7 meter so is it possible to do this with it?
Second how I can zoom is there any for that??

Thanks

Hi, you can use the telephoto lens to see farther which will give you a 4x zoom buy narrow the field of view by 4x. You can also run the QR code example demo program which does a 2x digital zoom.

That said, QR codes aren't designed for this type of thing. If you want to add visual fiducials to objects please use Apriltags.
