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() [1/2]

cv::aruco::GridBoard::GridBoard ( const Size size,
float  markerLength,

GridBoard constructor.

Parameters
sizenumber of markers in x and y directions
markerLengthmarker side length (normally in meters)
markerSeparationseparation between two markers (same unit as markerLength)
dictionarydictionary of markers indicating the type of markers
idsset of marker ids in dictionary to use on board.
