SquareImage_to_FiducialDetector

public SquareImage_to_FiducialDetector(DetectFiducialSquareImage<T> alg)

Method Details

addPatternImage

public void addPatternImage(T pattern,
 double threshold,
 double lengthSide)

Add a new pattern to be detected. This function takes in a raw gray scale image and thresholds it.

Parameters:

pattern - Gray scale image of the pattern

threshold - Threshold used to convert it into a binary image

lengthSide - Length of a side on the square in world units.

getSideWidth

public double getSideWidth(int which)

Description copied from class: FiducialDetectorPnP

Width of the fiducial. used to compute stability

Specified by:

getSideWidth in class FiducialDetectorPnP<T extends ImageGray<T>>

Parameters:

which - specifies which fiducial

Returns:

the width

getSideHeight

public double getSideHeight(int which)

Description copied from class: FiducialDetectorPnP

Height of the fiducial. used to compute stability

Specified by:

getSideHeight in class FiducialDetectorPnP<T extends ImageGray<T>>

Parameters:

which - specifies which fiducial

Returns:

the height

addPatternBinary

public void addPatternBinary(GrayU8 binary,
 double lengthSide)

Add a new pattern to be detected.

Parameters:

binary - Binary image of the pattern. 0 = black, 1 = white.

lengthSide - Length of a side on the square in world units.

getWidth

public double getWidth(int which)

Description copied from interface: FiducialDetector

Returns the width of the fiducial in world units. If not square then it returns a reasonable approximation. Intended for use in visualization and not precise calculations.

Parameters:

which - Fiducial's index

Returns:

Fiducial's width.
