Detailed description
aruco.detectMarkers() fails at a certain angle while the image is perfect
It should be ok for opencv to detect this marker as aruco.detectMarkers() performed well when I rotated the marker.
Steps to reproduce
import cv2
arucoDict = cv2.aruco.Dictionary_get(cv2.aruco.DICT_4X4_50)
arucoParams = cv2.aruco.DetectorParameters_create()
# arucoParams.adaptiveThreshConstant=10 #I have tried all these parameters
arucoParams.adaptiveThreshWinSizeStep=3
arucoParams.adaptiveThreshWinSizeMax=80
arucoParams.aprilTagMaxNmaxima=40
# arucoParams.aprilTagCriticalRad=0
# arucoParams.aprilTagMinClusterPixels=0
arucoParams.maxErroneousBitsInBorderRate=0.4
# arucoParams.errorCorrectionRate=0.8
arucoParams.perspectiveRemoveIgnoredMarginPerCell=0.3
arucoParams.polygonalApproxAccuracyRate=0.1
arucoParams.maxMarkerPerimeterRate =4
arucoParams.minCornerDistanceRate=0
arucoParams.minDistanceToBorder=0
mask=cv2.imread('failmask.png')
img=cv2.imread('failimg.png')
(corners, ids, rejected) = cv2.aruco.detectMarkers(mask, arucoDict,parameters=arucoParams)
print(ids)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)
