Hi ! I have implemented an algorithm that detects several QR Codes using OpenCV for Android. I now would like to know the distance between my camera and the QR Code. I believe this can actually be done since I know the size of the code in the image, I also know the vertices points of three markers I identified. Anyone can recomend some reading on this subject?

Thanks
