Detailed Description

Planar board with grid arrangement of markers.

More common type of board. All markers are placed in the same plane in a grid arrangement. The board image can be drawn using generateImage() method.

Constructor & Destructor Documentation

GridBoard()

cv::aruco::GridBoard::GridBoard()

Python:

cv.aruco.GridBoard(size, markerLength, markerSeparation, dictionary[, ids]) -> <aruco_GridBoard object>

GridBoard()

cv::aruco::GridBoard::GridBoard(
const Size & size,
float markerLength,
float markerSeparation,
const Dictionary & dictionary,
InputArray ids = noArray() )

Python:

cv.aruco.GridBoard(size, markerLength, markerSeparation, dictionary[, ids]) -> <aruco_GridBoard object>

GridBoard constructor.

Parameters

• size — number of markers in x and y directions

• 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

• ids — set of marker ids in dictionary to use on board.
