Board of markers A board is a set of markers in the 3D space with a common coordinate system. The common form of a board of marker is a planar (2D) board, however any 3D layout can be used. A Board object is composed by: - The object points of the marker corners, i.e. their coordinates respect to the board system. - The dictionary which indicates the type of markers of the board - The identifier of all the markers in the board.
