Aruco detector giving false positive

C++

For some reason Aruco detector is giving a false positive (id 37 in the picture). I can see that there’s some white spots in that black square so I am assuming it makes the cut to be counted as marker. Is there a way to make the aruco detector more pedantic for this case? seems like by default is a little relaxed.

snippet used (pretty much same as the OpenCV Aruco Tutorial)

cv::aruco::Dictionary dictionary = cv::aruco::getPredefinedDictionary(cv::aruco::DICT_5X5_1000);
cv::aruco::DetectorParameters params = cv::aruco::DetectorParameters();
cv::aruco::ArucoDetector detector(dictionary, params);
detector.detectMarkers(image, marker_corners, marker_ids, rejectedMarkers);

This code was used to generate the Charuco board. The Charuco paremeters 19x54, 0.05, 0.04, DICT_5X5_1000, legacy_charuco = true

cv::Ptr<cv::aruco::CharucoBoard> board = cv::makePtr<cv::aruco::CharucoBoard>(cv::Size(19, 34), 0.05f, 0.04f, dictionary);
board->setLegacyPattern(true);
