原标题:Copy an cv::Mat inside a ROI of another one

需将<代码>cv:Mat 图像(资料来源)复制到另一个仪器(印章)<代码>cv:

I found this reference, but it seems that it does not work for my case. Do you have any pointers how could I do this using the OpenCV C++ interface?

最佳回答

开放CV 2.4:

src.copyTo(dst(Rect(left, top, src.cols, src.rows)));

开放CV 2.x:

Mat dst_roi = dst(Rect(left, top, src.cols, src.rows));
src.copyTo(dst_roi);
问题回答

除上述答复外,如果你希望复制一个较小的开放区域<代码>Mat至另一个<代码>,请:

src(Rect(left,top,width, height)).copyTo(dst);

我的工作方式如下:

Mat imgPanel(100, 250, CV_8UC1, Scalar(0));
Mat imgPanelRoi(imgPanel, Rect(0, 0, imgSrc.cols, imgSrc.rows));
imgSrc.copyTo(imgPanelRoi);

imshow("imgPanel", imgPanel);
waitKey();

I am using Opencv 2.4.9 Based on Andrey s answer.
