| ArucoDetector
The main functionality of ArucoDetector class is detection of markers in an image with detectMarkers() method.
|
| 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/Set of markers, it contains the inner codification
BytesList contains the marker codewords where:
- bytesList.rows is the dictionary size
- each marker is encoded using
nbytes = ceil(markerSize*markerSize/8.)
- each row contains all 4 rotations of the marker, so its length is 4*nbytes
bytesList.ptr(i)[k*nbytes + j] is then the j-th byte of i-th marker, in its k-th rotation. |
