opencv 3.2 C ++ VS2015 imshow访问冲突执行

Question

我正在尝试使用sample代码通过笔记本电脑的嵌入式相机获取图像。我可以得到图像。但 imshow 语句会抛出执行访问冲突

任何人都可以帮我弄清楚原因吗？

非常感谢！

环境：Visual Studio 2015，Opencv 3.2

c ++代码：

using namespace cv;
using namespace std;
int main(int, char**)
{
    Mat frame;
    VideoCapture cap;
    cap.open(0);

    if (!cap.isOpened())
    {
        cerr << "ERROR, unable to open the camera\n";
        return -1;
    }
    std::cout << "start grapping" << endl;
    for (;;)
    {
        cap.read(frame);
        if (frame.empty())
        {
            cerr << "ERROR, blank frame grabbed \n";
            break;
        }

        // I added below statement to save the frame. 
        // check the frame from the camera.
        imwrite("D:\\CapturedImage.jpg", frame);

        // Below line throw Access violation executing location error
        imshow("Live", frame);
    }
}
