opencv读取摄像头实时流代码

opencv读取摄像头实时流代码：

 #include <opencv2/opencv.hpp>
 #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 ;
