opencv調用網路攝影機

#include <cstdio>#include <highgui.h>int main(){IplImage *pImg = NULL;CvCapture *cap = cvCaptureFromCAM(0);char fileName[100];char key;int count = 0;while(1){pImg = cvQueryFrame(cap);cvFlip(pImg, NULL, 1); //水平翻轉映像，像照鏡子一樣，不想要這個效果可以去掉此句key = cvWaitKey(50);if(key == 27) break; //按ESC鍵退出程式if(key == ' ')       //按空格鍵拍照{sprintf(fileName, "Picture %d.jpg", ++count); //組建檔案名cvSaveImage(fileName, pImg);cvXorS(pImg, cvScalarAll(255), pImg);         //將拍到的映像反色（閃一下形成拍照效果）cvShowImage("Camera",pImg);cvWaitKey(200); //反色映像顯示ms}cvShowImage("Camera",pImg);}cvReleaseCapture(&cap);return 0;}

藉助於百度雲，我們可以很好地實現拍照雲上傳功能。
