◆ create()

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

Create a GridBoard object.

Parameters
markersXnumber of markers in X direction
markersYnumber of markers in Y direction
markerLengthmarker side length (normally in meters)
markerSeparationseparation between two markers (same unit as markerLength)
dictionarydictionary of markers indicating the type of markers
firstMarkerid 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 
)
Python:
img=cv.aruco_GridBoard.draw(outSize[, img[, marginSize[, borderBits]]])

Draw a GridBoard.

Parameters
outSizesize of the output image in pixels.
imgoutput image with the board. The size of this image will be outSize and the board will be on the center, keeping the board proportions.
marginSizeminimum margins (in pixels) of the board in the output image
borderBitswidth of the marker borders.

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