问题描述

我想获取图像的宽度和高度，如何在OpenCV中做到这一点?

I want to get image width and height, how can I do that in OpenCV?

例如:

Mat src = imread("path_to_image");
cout << src.width;

对吗?

推荐答案

您可以使用rows和cols:

cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;

或size():

cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;
