准备工作

1. 安装Qt Creator

2. 下载OpenCV预编译库（
   Releases - OpenCV）

配置步骤 

下面的步骤都是针对MinGW版本的：

1. github上下载已编译的MinGW版本

        https://codeload.github.com/huihut/OpenCV-MinGW-Build/zip/refs/tags/OpenCV-3.4.8-x64

2.配置环境变量

        右键此电脑点开属性->高级系统设置->环境变量->在path中加入

（按照自己的安装路径配置--将bin文件夹放环境变量）：

D:\workspace\SOSAR_Imaging\SOSAR_Imaging_Process\mingw-opencv\OpenCV-MinGW-Build-OpenCV-3.4.8-x64\x64\mingw\bin

 Qt配置OpenCV

在项目的.pro文件中加入路径：
（依旧是安装自己的安装路径更改）

INCLUDEPATH+= ./mingw-opencv./OpenCV-MinGW-Build-OpenCV-3.4.8-x64./include
              ./mingw-opencv./OpenCV-MinGW-Build-OpenCV-3.4.8-x64./include./opencv2
              ./mingw-opencv./OpenCV-MinGW-Build-OpenCV-3.4.8-x64./include./opencv
LIBS += D:\workspace\SOSAR_Imaging\SOSAR_Imaging_Process\mingw-opencv\OpenCV-MinGW-Build-OpenCV-3.4.8-x64\x64\mingw\lib\libopencv_*.a

项目中使用opencv

#include <opencv2/opencv.hpp>

引入这个头文件即可使用
