QT 4.7.6 驱动 罗技C720摄像头

编译器： mingw32 gcc 4.8.1 

            mingw32 g++ 4.8.1 

QT 版本： 4.8.6 

OpenCV版本： 3.0.0 

测试平台： win7 x64 

-----------------------

重点： OpenCv 3.0.0 需要重新编译

         并对相关文件进行修改，否则无法使用qt 4.8.6 进行编译。

OpenCV测试代码： 

 OpenCv_test.cpp 

       

/*
*  filename: OpenCv_test.cpp 
*/ 

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <cv.hpp>
#include <cxcore.hpp>
#include <video/video.hpp>

using namespace cv;


int main()
{
    VideoCapture cap(0);
    if(!cap.isOpened())
    {
        return -1;
    }
    Mat frame;
    Mat edges;

    bool stop = false;
    while(!stop)
    {
        cap>>frame;
        cvtColor(frame, edges, /*CV_BGR2RGB*/CV_BGR2BGRA ); // 0


       // GaussianBlur(edges, edges, Size(7,7), 1.5, 1.5);
        //Canny(edges, edges, 0, 30, 3);
        imshow("Camera",edges);
        if(waitKey(30) >=0)
            stop = true;
    }
    return 0;
}
