項(xiàng)目需要將網(wǎng)絡(luò)攝像頭接入到服務(wù)器上，用c++或者python處理每幀的圖像。查了很多資料總算解決了，回過(guò)頭發(fā)現(xiàn)是很小的問(wèn)題，但是大華官網(wǎng)的SDK真的很難看懂。OpenCV2.4。
直接上代碼吧。

#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 openedif(!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;} }

大華的網(wǎng)絡(luò)攝像頭編號(hào)：DH-IPC-HFW1225M-I1-0600B，用的是RTSP協(xié)議。
“rtsp://admin:dahua@192.168.1.108/cam/realmonitor?channel=1&subtype=0”;
其中的admin，dahua是登錄攝像頭的用戶名和密碼。IP地址是192.168.1.108，可以根據(jù)具體情況修改。
