# 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 \

}

本安装包是通过2017年10月27日从官方Git网站上下载的主线代码编译而成，几乎包含了除CUDA全部的OpenCV3.3.1功能。希望能给使用OpenCV的开发人员带来方便

压缩包里包含了3个ZIP文件：
OpenCV-MinGW-Build-OpenCV-3.3.1.zip
OpenCV-MinGW-Build-OpenCV-3.4.7.zip
OpenCV-MinGW-Build-OpenCV-4.1.0.zip
这3个ZIP库是Windows系统下使用MinGW编译器编译的，可以在QT里调用使用，版本库是X86版本。
