Member Function Documentation

create()

static Ptr<GridBoard> cv::aruco::GridBoard::create ( int  markersX, int  markersY, float  markerLength, float  markerSeparation, const Ptr< Dictionary > &  dictionary, int  firstMarker = 0  )

static

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.

draw()

void cv::aruco::GridBoard::draw	(	Size	outSize,
		OutputArray	img,
		int	marginSize = 0,
		int	borderBits = 1
	)

Draw a GridBoard.

Parameters

outSize	size of the output image in pixels.
img	output image with the board. The size of this image will be outSize and the board will be on the center, keeping the board proportions.
marginSize	minimum margins (in pixels) of the board in the output image
borderBits	width of the marker borders.

This function return the image of the GridBoard, ready to be printed.
