Hello,

I am detecting a QR code with ZBAR library, and I have as information the 4 corners of the QR code, I can't find an answer to my question: is it possible by using only the position of the QR code (4 corners) to estimate the pose of the camera: if the camera is above, below, on the left or in the right of the QR code, the result of the pose can be for example an angle in degrees.

And thak you.

you can do that, using opencv, too ;)

@berak I have tested it, and according to my tests Zbar (version 0.10) is more stable than cv::QRCodeDetector (4.1.0 version). I think Zbar is the best library that exist to detect a QR code(maybe i am wrong).

Yes, current results are suboptimal: Performance:QrCode.

Look at solvePnP() and pose estimation topic.
