OPencv 将一张图片插入另一张图片的指定区域

Mat c=imread("car.png");//图片放工程底下

     Size c_dsize = Size(200, 350);//自适应大小

     Mat dst(c_dsize, c.type());//模板

     resize(c,dst,dst.size());//大小

     Mat aaa = dst(Rect(Point(62,110), Size(70, 140)));

     Mat allresult=resule+result_left+result_r+result_down;

     cv::Rect roi_rect = cv::Rect(62, 110, aaa.cols, aaa.rows);

     aaa.copyTo(allresult(roi_rect));

     cv::imshow("result", allresult);
