import cv2
import cv2.cv
def getcam():
window_name = 'show image'
cv2.namedwindow(window_name,cv2.window_normal)
video_cap_obj = cv2.videocapture( 0 )
if video_cap_obj = = none:
print ( 'video caoture error' )
if video_cap_obj. open ( 0 ) = = false:
print ( 'open error' )
while true:
retval,image = video_cap_obj.read()
cv2.cv.showimage(window_name,cv2.cv.fromarray(image))
if cv2.waitkey( 10 ) = = 27 :
break
video_cap_obj.release()
if __name__ = = '__main__' :
getcam()

效果如图:
