合并 cv::Mat 水平

问题描述

我想合并几个cv::Mat，当我使用mat1.push_back(mat2)时，它会在最后添加mat2mat1 垂直，有没有办法水平做到这一点?我能想到的唯一其他选择是将每个 cv::Mat 变成一个 cv::RotatedRect，旋转它，创建一个新的 Mat，合并，最后以同样的方式旋转所有东西，但如果有另一种方式，这听起来毫无意义

I want to merge a few cv::Mat, when I use mat1.push_back(mat2) it add mat2 to the end of mat1 vertically , is there a way to do this horizontally? The only other option I can think of is making every cv::Mat into a cv::RotatedRect, rotate it, creating a new Mat, merging, rotating everything in the end in the same way, but it sound pointlessly long if there is another way

推荐答案

看一看 hconcat 和 vconcat.

用法:

Mat M1,M2,HM,VM;
// M1 and M2 - source matrices
// HM,VM - results matrices
 ...

 hconcat(M1,M2,HM); // horizontal concatenation
 vconcat(M1,M2,VM); // vertical   concatenation

注意，这些方法没有记录.

Take care, these methods are not documented.
