setCharucoParameters results in segfault when using the python opencv #23440
Description
System Information
OpenCV python version: 4.7.0.74
Operating System / Platform: Ubuntu 18.04
Python version: 3.10
Detailed description
Setting CharucoParameters either in the constructor or using detector.setCharucoParameters causes a segfault
Steps to reproduce
dictionary = cv2.aruco.getPredefinedDictionary(cv2.aruco.DICT_4X4_1000)
board = cv2.aruco.CharucoBoard((10, 10), 0.019, 0.015, dictionary)
detector = cv2.aruco.CharucoDetector(board)
works
but
dictionary = cv2.aruco.getPredefinedDictionary(cv2.aruco.DICT_4X4_1000)
board = cv2.aruco.CharucoBoard((10, 10), 0.019, 0.015, dictionary)
charuco_parameters = cv2.aruco.CharucoParameters()
detector = cv2.aruco.CharucoDetector(board, charucoParams=charuco_parameters)
causes a segfault
dictionary = cv2.aruco.getPredefinedDictionary(cv2.aruco.DICT_4X4_1000)
board = cv2.aruco.CharucoBoard((10, 10), 0.019, 0.015, dictionary)
charuco_parameters = cv2.aruco.CharucoParameters()
detector = cv2.aruco.CharucoDetector(board)
detector.setCharucoParameters(charuco_parameters)
also segfaults
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)
