+# OpenCV-MinGW-Build
+
+MinGW 32bit and 64bit version of OpenCV compiled on Windows.
+
+## MinGW32
+
+### Compiling Environment
+
+* MinGW-x32-5.3.0
+* Windows-10-64bit
+* CMake-3.9.2
+
+### [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
+```
+
+## MinGW-w64
+
+### Compiling Environment
+
+* MinGW-x64-4.8.1-release-posix-seh-rev5
+* Windows-10-64bit
+* CMake-3.12.0
+
+### [OpenCV 3.4.1-x64](https://github.com/huihut/OpenCV-MinGW-Build/tree/OpenCV-3.4.1-x64) 
+
+Unselected `WITH_QT`
+
+```
+git clone -b OpenCV-3.4.1-x64 git@github.com:huihut/OpenCV-MinGW-Build.git
+```
+
+## How to compile OpenCV
+
+* [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/)
+* [wiki.qt . How to setup Qt and openCV on Windows](https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows)
+* [Tutorial: Installation from source for Windows with Mingw-w64](http://visp-doc.inria.fr/doxygen/visp-daily/tutorial-install-win10-mingw64.html)
+
+## 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 \
