detector = cv.aruco.ArucoDetector(board.getDictionary(), detector_parameters)
corners, ids, rejected = detector.detectMarkers(gray)Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files (videos, images, onnx, etc)
