boofcv.alg.fiducial.qrcode.QrCodeBinaryGridToPixel

public class QrCodeBinaryGridToPixel
extends Object

Given a set of control points, it computes a distortion model and allows the user to read the value of grid elements.

Method Details
- setTransformFromSquare
  
  public void setTransformFromSquare(Polygon2D_F64 square)
- setTransformFromLinesSquare
  
  public void setTransformFromLinesSquare(QrCode qr)
  
  Used to estimate the image to grid coordinate system before the version is known. The top left square is used to fix the coordinate system. Then 4 lines between corners going to other QR codes is used to make it less suspectable to errors in the first 4 corners
- addAllFeatures
  
  public void addAllFeatures(QrCode qr)
- removeOutsideCornerFeatures
  
  public void removeOutsideCornerFeatures()
  
  Outside corners on position patterns are more likely to be damaged, so remove them
- removeFeatureWithLargestError
  
  public boolean removeFeatureWithLargestError()
- computeTransform
  
  public void computeTransform()
- imageToGrid
  
  public final void imageToGrid(float x, float y, Point2D_F32 grid)
- imageToGrid
  
  public final void imageToGrid(double x, double y, Point2D_F64 grid)
- gridToImage
  
  public final void gridToImage(float row, float col, Point2D_F32 pixel)
- setAdjustWithFeatures
  
  public void setAdjustWithFeatures(boolean adjustWithFeatures)
- setHomographyInv
  
  public void setHomographyInv(Homography2D_F64 Hinv)
