無法使用opencv初始化mac上的ps3 eye，但c例子工作正常

Question

我已經通過執行以下「port install opencv + python27」通過macports安裝OpenCV。使用C並調用cvCaptureFromCAM（0）我可以很好地從凸輪捕獲幀。當我用python的cv.CaptureFromCAM嘗試（0）它具有以下死亡：

QTKit didn't find any attached Video Input Devices! 
Warning, camera failed to properly initialize! 
Cleaned up camera. 
Traceback (most recent call last): 
    File "test.py", line 5, in <module> 
    temp=cv.CloneImage(frame) 

Answer 1

與Python你可以嘗試CV2接口：

import cv2 

# initiate the capture interface 
cv2.VideoCapture() # that's right, no params
