| ArucoDetector
The main functionality of ArucoDetector class is detection of markers in an image with detectMarkers() method.
|
| BarcodeDetector |
| BaseCascadeClassifier |
| Board
Board of ArUco markers
A board is a set of markers in the 3D space with a common coordinate system.
|
| CascadeClassifier
Cascade classifier class for object detection.
|
| CharucoBoard
ChArUco board is a planar chessboard where the markers are placed inside the white squares of a chessboard.
|
| CharucoDetector |
| CharucoParameters |
| DetectorParameters
struct DetectorParameters is used by ArucoDetector
|
| 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. |
