# OpenCV-MinGW-Build
MinGW version of OpenCV compiled on Windows.
## [OpenCV 3.4.1](https://github.com/huihut/OpenCV-MinGW-Build/tree/OpenCV-3.4.1)
```
git clone -b OpenCV-3.4.1 git@github.com:huihut/OpenCV-MinGW-Build.git
```
## [OpenCV 3.3.1](https://github.com/huihut/OpenCV-MinGW-Build/tree/OpenCV-3.3.1)
```
git clone -b OpenCV-3.3.1 git@github.com:huihut/OpenCV-MinGW-Build.git
```
## Compiling Environment
* Windows-10-64bit
* MinGW-5.3.0-32bit
* CMake-3.9.2
## How to compile OpenCV
* [wiki.qt . How to setup Qt and openCV on Windows](https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows)
* [blog.huihut . OpenCV使用CMake和MinGW的编译安装及其在Qt配置运行](https://blog.huihut.com/2017/12/03/CompiledOpenCVRunInQt/)
## Using OpenCV in Qt
Add OpenCV library file and include path to Qt `.pro` file.
* My version of OpenCV : `OpenCV 3.3.1`
* My OpenCV path : `E:\OpenCV_3.3.1\OpenCV-MinGW-Build`
So the configuration is as follows (**You need to modify it according to your OpenCV.**) :
```
win32 {
INCLUDEPATH += E:\OpenCV_3.3.1\OpenCV-MinGW-Build\include
LIBS += E:\OpenCV_3.3.1\OpenCV-MinGW-Build\bin\libopencv_*.dll
}
```
or
```
win32 {
INCLUDEPATH += E:\OpenCV_3.3.1\OpenCV-MinGW-Build\include
LIBS += -LE:\OpenCV_3.3.1\OpenCV-MinGW-Build\bin \
-llibopencv_calib3d331 \
-llibopencv_core331 \
-llibopencv_dnn331 \
-llibopencv_features2d331 \
-llibopencv_flann331 \
-llibopencv_highgui331 \
-llibopencv_imgcodecs331 \
-llibopencv_imgproc331 \
-llibopencv_ml331 \
-llibopencv_objdetect331 \
-llibopencv_photo331 \
-llibopencv_shape331 \
-llibopencv_stitching331 \
-llibopencv_superres331 \
-llibopencv_video331 \
-llibopencv_videoio331 \
-llibopencv_videostab331
}
```

OpenCV是一个基于BSD许可（开源）发行的跨平台计算机视觉库，可以运行在Linux、Windows、Android和Mac OS操作系统上。它轻量级而且高效——由一系列 C 函数和少量 C++ 类构成，同时提供了Python、Ruby、MATLAB等语言的接口，实现了图像处理和计算机视觉方面的很多通用算法。

opencv3.4.6 适用于 win10 & win11，用于计算机视觉图像处理
使用方法：
(1) 解压 opencv3.4.6.zip;
(2) 双击 opencv3.4.6.exe，生成opencv的头和库；
(3) 以三方库形式引入，以构建图像处理工程；
备注：内含完整的debeg和release库
