opencv3.3+vs2015调用笔记本摄像头成功

先上代码

成功图片如下：

#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/core/core.hpp>
using namespace cv;
int main()
{
    VideoCapture cap();
    if (!cap.isOpened())
    {
        return -;
    }
    Mat frame;
    Mat edges;
    bool stop = false;
    while (!stop)
    {
        cap >> frame;
        cvtColor(frame, edges, CV_BGR2GRAY);
        GaussianBlur(edges, edges, Size(, ), 1.5, 1.5);
        Canny(edges, edges, , , );
        imshow("当前视频", edges);
        if (waitKey() >= )
            stop = true;
    }
    return ;
}

前提是你已经正确配置了opencv和vs2015
