ArucoInvokeDetectMarkers Method

http://www.emgu.com
Performs marker detection in the input image. Only markers included in the specific dictionary are searched. For each detected marker, it returns the 2D position of its corner in the image and its corresponding identifier. Note that this function does not perform pose estimation.

Namespace:  Emgu.CV.Aruco
Assembly:  Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.0.3408 (4.1.0.3408)
Syntax
Copy
public static void DetectMarkers(
	IInputArray image,
	Dictionary dict,
	IOutputArrayOfArrays corners,
	IOutputArray ids,
	DetectorParameters parameters,
	IOutputArrayOfArrays rejectedImgPoints = null
)

Parameters

image
Type: Emgu.CVIInputArray
input image
dict
Type: Emgu.CV.ArucoDictionary
indicates the type of markers that will be searched
corners
Type: Emgu.CVIOutputArrayOfArrays
Vector of detected marker corners. For each marker, its four corners are provided, (e.g VectorOfVectorOfPointF ). For N detected markers, the dimensions of this array is Nx4. The order of the corners is clockwise.
ids
Type: Emgu.CVIOutputArray
vector of identifiers of the detected markers. The identifier is of type int (e.g. VectorOfInt). For N detected markers, the size of ids is also N. The identifiers have the same order than the markers in the imgPoints array.
parameters
Type: Emgu.CV.ArucoDetectorParameters
marker detection parameters
rejectedImgPoints (Optional)
Type: Emgu.CVIOutputArrayOfArrays
contains the imgPoints of those squares whose inner code has not a correct codification. Useful for debugging purposes.
