boofcv.alg.fiducial.qrcode.SquareLocatorPatternDetectorBase<T>

boofcv.alg.fiducial.qrcode.QrCodePositionPatternDetector<T>

All Implemented Interfaces:

VerbosePrint

public class QrCodePositionPatternDetector<T extends ImageGray<T>>
extends SquareLocatorPatternDetectorBase<T>

Detects position patterns for a QR code inside an image. This is done by detecting squares and seeing if they have the expected shape.

If a lens distortion model is provided the returned pixel coordinates will be in an undistorted image
