Tuple has no attribute

0 votes
I'm running python code on the Jevois to identify rectangular areas and pass them over USB to a raspberry pi. All the open CV code seems to work fine and I obtain my RotatedRect using minAreaRect. I encounter a problem when I try to access attributes of the rectangle. For example, if I try to access rect.center.x, I'm told that the 'tuple' has no attribute 'center'. If I try to dump the RotatedRect structure using json.dump, all of the data is there, but there are no tuple names.

I'm a python newbie, so hopefully this is something dumb I'm doing and easy to fix.

Any and all assistance is appreciated.

How about this hit from googling "python minAreaRect":


example 4 tells you:

  # help(cv2.minAreaRect)
  (x, y), (width, height), rect_angle = rectangle
so you could try that code. Or, if you just want to extract the fields from your rectangle, I guess rect[0] is (x, y) and rect[0][0] is x
and rect[1] is (width, height) and rect[1][0] is width
and so on, the other examples should help you.
