opencv打开双目摄像头

#include <opencv2/>
using namespace std;
int main()
{   
//initialize and allocate memory to load the video stream from camera     
cv::VideoCapture camera0(1);  
  camera0.set(CV_CAP_PROP_FRAME_WIDTH,320);  
  camera0.set(CV_CAP_PROP_FRAME_HEIGHT,240);  
  cv::VideoCapture camera1(0);  
  (CV_CAP_PROP_FRAME_WIDTH,320);
   (CV_CAP_PROP_FRAME_HEIGHT,240);   
if( !camera0.isOpened() )
return 1;  
  if( !() )
return 1;
   while(true)
   {   
    //grab and retrieve each frames of the video sequentially      
     cv::Mat frame0;     
     camera0 >> frame0;   
     cv::Mat frame1;      
      camera1 >> frame1;      
     cv::imshow("left", frame0);      
     cv::imshow("right", frame1);  
     //  std::cout << () << std::endl;      
     //wait for 40 milliseconds      
    int c = cvWaitKey(40);   
     //exit the loop if user press "Esc" key  (ASCII value of "Esc" is 27)      
    if(27 == char(c))
    break;
    }  
  return 0;
}

编译之后直接运行即可，若有两个以上摄像头，只需要修改摄像头对应参数即可。
