Python+OpenCV采集本地摄像头的视频

本文实现了用Python和OpenCV配合，调用本地摄像头采集视频，基本上函数的话看opencv的官方文档就Ok了(The OpenCV Reference Manual  Release 2.4.7.0)

上代码：

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：
