I am using my Pi to experiment with a little project and I am trying to capture video via the Pi camera (to begin with). On the OpenCV website I found this very simple piece of code but unfortunately when I run it it produces an error (The error begins with "Assertion failed". Any suggestions please?
Here is the code:
Code: Select all
import numpy as np import cv2 cap = cv2.VideoCapture(0) while(True): # Capture frame-by-frame ret, frame = cap.read() # convert in gray gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) # Display the resulting frame cv2.imshow('frame',gray) if cv2.waitKey(1) & 0xFF == ord('q'): break # When everything done, release the capture cap.release() cv2.destroyAllWindows()
