Method Detail

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.

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.
