I'm writing a python script to perform camera calibration with OpenCV.

I found that the cv2.findChessboardCorners function may take very long to run on certain images.

I would therefore like to be able to stop the function after a certain period of time has passed, and move on to the next image.

How do I do that?

for fname in images:        
    img = cv2.imread(fname)                            
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    ret, corners = cv2.findChessboardCorners(gray, (20, 17), None)
