    • process

      public boolean process​(GrayF32 input)
      Description copied from interface: DetectSingleFiducialCalibration
      Image processing for calibration target detection
      Specified by:
      process in interface DetectSingleFiducialCalibration
      Parameters:
      input - Gray scale image containing calibration target
      Returns:
      true if target was detected and false if not
    • createLayout

      public static List<Point2D_F64> createLayout​(int numRows, int numCols, double squareWidth, double spaceWidth)
      Creates a target that is composed of squares. The squares are spaced out and each corner provides a calibration point.
      Parameters:
      numRows - Number of rows in calibration target. Must be odd.
      numCols - Number of column in each calibration target. Must be odd.
      squareWidth - How wide each square is. Units are target dependent.
      spaceWidth - Distance between the sides on each square. Units are target dependent.
      Returns:
      Target description
    • getDetectedPoints

      public CalibrationObservation getDetectedPoints()
      Description copied from interface: DetectSingleFiducialCalibration
      Returns the set of detected points from the most recent call to DetectSingleFiducialCalibration.process(GrayF32). Each time this function is invoked a new instance of the list and points is returned. No data reuse here.
      Specified by:
      getDetectedPoints in interface DetectSingleFiducialCalibration
      Returns:
      List of detected points in row major grid order.
    • getLayout

      public List<Point2D_F64> getLayout()
      Description copied from interface: DetectSingleFiducialCalibration
      Returns the layout of the calibration points on the target
      Specified by:
      getLayout in interface DetectSingleFiducialCalibration
      Returns:
      List of calibration points
    • setLensDistortion

      public void setLensDistortion​(@Nullable @Nullable LensDistortionNarrowFOV distortion, int width, int height)
      Description copied from interface: DetectSingleFiducialCalibration
      Explicitly handles lens distortion when detecting image features. If used, features will be found in undistorted pixel coordinates
      Specified by:
      setLensDistortion in interface DetectSingleFiducialCalibration
    • getAlgorithm

      public DetectSquareGridFiducial<GrayF32> getAlgorithm()
    • getGridRows

      public int getGridRows()
      Returns number of rows in the grid
      Returns:
      number of rows
    • getGridColumns

      public int getGridColumns()
      Returns number of columns in the grid
      Returns:
      number of columns
    • getPointRows

      public int getPointRows()
      Returns number of rows in calibration point grid
      Returns:
      number of rows
    • getPointColumns

      public int getPointColumns()
      Returns number of columns in calibration point grid
      Returns:
      number of columns
