Method Detail

process

public boolean process(GrayF32 input)

Description copied from interface: CalibrationDetector

Image processing for calibration target detection

Specified by:

process in interface CalibrationDetector

Parameters:

input - Gray scale image containing calibration target

Returns:

true if target was detected and false if not

getDetectedPoints

public CalibrationObservation getDetectedPoints()

Description copied from interface: CalibrationDetector

Returns the set of detected points from the most recent call to CalibrationDetector.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 CalibrationDetector

Returns:

List of detected points in row major grid order.

getLayout

public java.util.List<Point2D_F64> getLayout()

Description copied from interface: CalibrationDetector

Returns the layout of the calibration points on the target

Specified by:

getLayout in interface CalibrationDetector

Returns:

List of calibration points

getGridRows

public int getGridRows()

Returns number of rows in the chessboard grid

Returns:

number of rows

getGridColumns

public int getGridColumns()

Returns number of columns in the chessboard grid

Returns:

number of columns

getAlgorithm

public DetectChessboardFiducial<GrayF32> getAlgorithm()

gridChess

public static java.util.List<Point2D_F64> gridChess(int numRows,
                                                    int numCols,
                                                    double squareWidth)

This target is composed of a checkered chess board like squares. Each corner of an interior square touches an adjacent square, but the sides are separated. Only interior square corners provide calibration points.

Parameters:

numRows - Number of grid rows in the calibration target

numCols - Number of grid columns in the calibration target

squareWidth - How wide each square is. Units are target dependent.

Returns:
