我在Ubuntu上用python和opencv编程,但cv2.destoyAllWindows()似乎不起作用,如下例所示:
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
# Capture frame-by-frame
ret, frame = cap.read()
# Our operations on the frame come here
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()
当我按“q”键时,程序结束了,但窗口仍然在屏幕上。然而在windows上,我从来没有面对过这样的事情 任何帮助我都会感激的
