Hello,I would like to ask you the problem down below . Because I really want to successfully implement the system you wrote. But there are some problems now. I really need your help Since no one around me can solve this problem, I have been researching it for two weeks now hope you can help me soon. ---------------------------------------------------------------(i think the main problem ) im = imutils.resize(im1, width=416) r = width / float(w) ZeroDivisionError: float division by zero

Hi, @gigisu20 I'll try my best to help you. this is a very old project. I can help you to rewrite it if you want. this code is very messy.
To debug your problem, can you do the following checks to see

1. if you can get frame from camera

   
   
              cap = cv2.VideoCapture(CAMERA_IP[i])
              ret, frame = cap.read()
              if not ret:
                   raise(f'Error: failed to capture from {CAMERA_IP[i]}')

2.print the frame shape and the crop region 
```python
               ##Crop out seats images from the full picture
               for i in seatTemp:
                    print(frame.shape)
                    print(i["x1Img"],i["x2Img"],i["y1Img"],i["y2Img"])
