这个问题在开源里面问过，但是一直都没有准确的回音：

 import cv
import time 
if __name__ == '__main__':
cv.NamedWindow("camera",1)
capture = cv.CaptureFromCAM(0)
while True:        
img = cv.QueryFrame(capture)
    cv.ShowImage("camera",img)
    mm = int(time.strftime('%S',time.localtime()))
    if mm == 30:
        filename = "e:\pic\o\%s.jpg" % time.strftime('%Y%m%d%H%M%S',time.localtime())
    #time.sleep(2)
        cv.SaveImage(filename,img)
    if cv.WaitKey(10) == 27:
        break
cv.DestroyWindow("camera")

同时使用dpkg -L python-opencv命令查看如下：

报错代码如下：

Traceback (most recent call last):
File "/home/ubulinux/application/untitled/thenewtest.py", line 2, in <module>
import cv
ImportError: No module named cv </module>

Process finished with exit code 1
就算是将 import cv 改成 import cv2也不行，还是一样的报错
同时需要声明的是我使用的是ubuntu 12.10系统
