create

public static GridBoard create(int markersX,
                               int markersY,
                               float markerLength,
                               float markerSeparation,
                               Dictionary dictionary,
                               int firstMarker)

Create a GridBoard object

Parameters:

markersX - number of markers in X direction

markersY - number of markers in Y direction

markerLength - marker side length (normally in meters)

markerSeparation - separation between two markers (same unit as markerLength)

dictionary - dictionary of markers indicating the type of markers

firstMarker - id of first marker in dictionary to use on board.

Returns:

the output GridBoard object This functions creates a GridBoard object given the number of markers in each direction and the marker size and marker separation.

                               float markerSeparation,
                               Dictionary dictionary)

Create a GridBoard object

Parameters:

markersX - number of markers in X direction

markersY - number of markers in Y direction

markerLength - marker side length (normally in meters)

markerSeparation - separation between two markers (same unit as markerLength)
