opencv读取摄像头实时流代码

opencv读取摄像头实时流代码：

 #include <iostream>

 using namespace cv;

 using namespace std;

 int main()

 {

     VideoCapture inputCamera;

     string videoStreamAddress = "此处填写摄像机的URL";

     inputCamera.open(videoStreamAddress);

     if (!inputCamera.isOpened())

     {

         cout << "摄像头打开失败！" << endl;

         return false;

     }

     // obtain the video parameters

     int rate = inputCamera.get(CV_CAP_PROP_FPS);         //the rate of video frame

     int frameHeight = inputCamera.get(CV_CAP_PROP_FRAME_HEIGHT);  // the height of video frame

     int frameWidth = inputCamera.get(CV_CAP_PROP_FRAME_WIDTH);    // the width of video frame

     Mat cutImage;

     char c;

     while (true)

     {

         inputCamera >> cutImage;

         imshow("cutImage", cutImage);

         c = waitKey();

         if (c == ) break;

     }

     return ;
