我是CV的初學者。我的相機每次都崩潰。我的意思是相機燈亮了但是沒有相機顯示有人可以幫我嗎？這是代碼
import cv2 as cv
import numpy as np
cap=cv.VideoCapture(0)
# read webcam untill the end
while (cap.isOpened()):
# capture frame by frame
ret,frame=cap.read()
if ret == True:
# to display frame
cv.imshow("Frame",frame)
else:
break
cv.waitKey(1)
cap.release()
cv.destroyAllWindows()

我認為您將 waitKey 放在錯誤的位置，我希望下面的代碼可以正常作業！
import cv2 as cv
cap = cv.VideoCapture(0)
# read webcam untill the end
while (cap.isOpened()):
# capture frame by frame
ret, frame = cap.read()
if ret == True:
# to display frame
cv.imshow("Frame", frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
else:
break
cap.release()
cv.destroyAllWindows()

@tahir mehmood。我修改了您的代碼，并對其進行了測驗。作業得很好。
import cv2 as cv
import numpy as np
cap=cv.VideoCapture(0)
# read webcam untill the end
while (cap.isOpened()):
# capture frame by frame
ret,frame=cap.read()
if not ret:
break
cv.imshow("Frame",frame)
cv.waitKey(1)
cap.release()
cv.destroyAllWindows()
