我在ubuntu 11.04上使用opencv 2.3。编译时,为了完整起见,我将WITH_OPENNI = ON。 (现在很遗憾,因为我不打算很快使用kinect,并且openni给我带来了正常的opencv程序带来的麻烦)openNI干扰cvCreateCameraCapture()

无论如何,我测试了opencv安装,我编译了下面的代码,显示了我的笔记本电脑摄像头的视频:

#include <stdio.h> 
#include <string.h> 
#include "highgui.h" 
#include "cv.h" 

int main() 
{ 
cvNamedWindow("Webcam",CV_WINDOW_AUTOSIZE); 
CvCapture* capture=cvCaptureFromCAM(0); 
IplImage* frame; 

while(1) 
{ 
    frame=cvQueryFrame(capture); 
    if(!frame) break; 
    cvShowImage("Webcam",frame); 
    char c=cvWaitKey(33); 
    if(c==27) break; 
} 

cvReleaseCapture(&capture); 
cvDestroyWindow("Webcam"); 
} 

代码符合正确,但给出了执行以下错误:

OpenCV Error: Unspecified error (Failed to enumerate production trees: Can't create any node of the requested type!) in CvCapture_OpenNI, file /home/samarth/OpenCV-2.3.0/modules/highgui/src/cap_openni.cpp, line 188 terminate called after throwing an instance of 'cv::Exception' what(): /home/samarth/OpenCV-2.3.0/modules/highgui/src/cap_openni.cpp:188: error: (-2) Failed to enumerate production trees: Can't create any node of the requested type! in function CvCapture_OpenNI

中止

已有人面临吨他同样的问题?任何想法来解决这个问题将不胜感激。
