CalibrationDetectorChessboardBinary

public CalibrationDetectorChessboardBinary(ConfigChessboardBinary configDet,
 ConfigGridDimen configGrid)

Method Details

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

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

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 DetectChessboardBinaryPattern<GrayF32> getAlgorithm()

gridChess

public static 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:
