图像处理

项目需要将网络摄像头接入到服务器上，用c++或者[Python][]处理每帧的图像。查了很多资料总算解决了，回过头发现是很小的问题，但是大华官网的SDK真的很难看懂。OpenCV2.4。   
直接上代码吧。

<code class="hljs cpp has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">#include "cv.h"
 #include "highgui.h"
 #include <stdio.h>
 using namespace std;
 using namespace cv;
 
 int main(int, char**) {
 VideoCapture vcap;
 Mat image;
 
 const string videoStreamAddress = "rtsp://admin:dahua@192.168.1.108/cam/realmonitor?channel=1&subtype=0";
 /* it may be an address of an mjpeg stream,
 e.g. "http://user:pass@cam_address:8081/cgi/mjpg/mjpg.cgi?.mjpg" */
 
 //open the video stream and make sure it's opened
 if(!vcap.open(videoStreamAddress)) {
 cout << "Error opening video stream or file" << endl;
 return -1;
 }else{
 cout<<"success"<<endl;
 }
 
 //Create output window for displaying frames.
 //It's important to create this window outside of the `for` loop
 //Otherwise this window will be created automatically each time you call
 //`imshow(...)`, which is very inefficient.
 namedWindow("Output Window");
 for(;;) {
 if(!vcap.read(image)) {
 cout << "No frame" << endl;
 waitKey();
 }
 imshow("Output Window", image);
 if(waitKey(1) >= 0) break;
 }
 }

大华的网络摄像头编号：DH-IPC-HFW1225M-I1-0600B，用的是RTSP协议。   
“rtsp://admin:dahua@192.168.1.108/cam/realmonitor?channel=1&subtype=0”;   
其中的admin，dahua是登录摄像头的用户名和密码。IP地址是192.168.1.108，可以根据具体情况修改。
