opencv3使用addWeight函数出现错误

Question

下面是我的代码 错误显示为：
0x00007FFD8EC79E08 处(位于 ConsoleApplication7.exe 中)引发的异常: Microsoft C++ 异常: cv::Exception，位于内存位置 0x0000008EA356EEB0 处。
经过设置断点已经确定是addWeight处出现的问题了。

 #include<opencv2/core/core.hpp>
#include<opencv2\highgui\highgui.hpp>

using namespace cv;


int main()
{
    Mat girl = imread("girl.jpg");
    namedWindow("1.动漫图");
    imshow("1.动漫图", girl);

    Mat image = imread("dota.jpg", 1);
    Mat logo = imread("dota_logo.jpg");

    namedWindow("2.Yuanhua");
    imshow("2.Yuanhua", image);

    namedWindow("3.Yuanhua");
    imshow("3.Yuanhua", logo);

    Mat imageROI;
    imageROI = image(Rect(800,350,logo.cols,logo.rows));

    addWeighted(imageROI, 0.5,logo,0.3,0.,imageROI);


    namedWindow("4.Yuanhua+logo");
    imshow("4.Yuanhua+logo", image);

    imwrite("生成得.jpg", image);

    waitKey();

    return 0;

}
