cv::aruco Namespace Reference

Classes
class	Board
	Board of markers. More...
class	CharucoBoard
	ChArUco board Specific class for ChArUco boards. A ChArUco board is a planar board where the markers are placed inside the white squares of a chessboard. The benefits of ChArUco boards is that they provide both, ArUco markers versatility and chessboard corner precision, which is important for calibration and pose estimation. This class also allows the easy creation and drawing of ChArUco boards. More...
struct	DetectorParameters
	Parameters for the detectMarker process: More...
class	Dictionary
	Dictionary/Set of markers. It contains the inner codification. More...
class	GridBoard
	Planar board with grid arrangement of markers More common type of board. All markers are placed in the same plane in a grid arrangment. The board can be drawn using drawPlanarBoard() function (. More...
