    Description
    ArucoDetector
    The main functionality of ArucoDetector class is detection of markers in an image with detectMarkers() method.
    BarcodeDetector
     
    Board
    Board of ArUco markers A board is a set of markers in the 3D space with a common coordinate system.
    CChecker
    CChecker checker object This class contains the information about the detected checkers,i.e, their type, the corners of the chart, the color profile, the cost, centers chart, etc.
    CCheckerDetector
    A class to find the positions of the ColorCharts in the image.
    CharucoBoard
    ChArUco board is a planar chessboard where the markers are placed inside the white squares of a chessboard.

    DetectorParameters
    struct DetectorParameters is used by ArucoDetector
    DetectorParametersMCC
    struct DetectorParametersMCC is used by CCheckerDetector
    Dictionary
    Dictionary is a set of unique ArUco markers of the same size bytesList storing as 2-dimensions Mat with 4-th channels (CV_8UC4 type was used) and contains the marker codewords where: - bytesList.rows is the dictionary size - each marker is encoded using nbytes = ceil(markerSize*markerSize/8.) bytes - each row contains all 4 rotations of the marker, so its length is 4*nbytes - the byte order in the bytesList[i] row: //bytes without rotation/bytes with rotation 1/bytes with rotation 2/bytes with rotation 3// So bytesList.ptr(i)[k*nbytes + j] is the j-th byte of i-th marker, in its k-th rotation.
