基於OpenCv呼叫攝像頭並顯示

opencv3 計算機視覺 python實現 p25

在視窗顯示攝像頭幀

出現錯誤：

[ warn:0] videoio(msmf): onreadsample() is called with error status: -1072875772 [ warn:0] videoio(msmf): async readsample() call is failed with error status: -1072875772 [ warn:1] videoio(msmf): can』t grab frame. error: -1072875772

解決方法：

import cv2

cameracapture = cv2.videocapture(0 + cv2.cap_dshow)
success, frame = cameracapture.read()
while(cameracapture.isopened() & success):
success, frame = cameracapture.read()
cv2.imshow('image',frame)
if cv2.waitkey(1) & 0xff == ord('q'):
break
cameracapture.release()
cv2.destroyallwindows()
