以下无需要参考==>直接跳过到官方文件篇

资源(64位)下载地址

环境变量

勾选with_opengl with_qt configure

configure问题汇总 遇到问题了参考下列文章解析

错误二 [modules\core\CMakeFiles\opencv_core.dir\build.make:1708: bin/libopencv_core450.dll] Error 1
设置OPENCV_VS_VERSIONINFO_SKIP=1，也就是打勾，若无法找到变量OPENCV_VS_VERSIONINFO_SKIP，则可以自己添加一个：

二、opencv_videoio_ffmpeg_64.dll、opencv_videoio_ffmpeg.dll下载失败
进入opencv3.4.2\sources\3rdparty\ffmpeg目录
将 ffmpeg.cmake 的https://raw.githubusercontent.com
修改为：https://raw.staticdn.net

flags.make文件 CXX添加 -O3 -fPIC

官方文件篇

经过一周时间的折腾查找资料再次三次，直到n次实践后，发现了​​官方​​​提供的配置过程,强烈推荐下列方式
编译环境

Windows 10 64,
Qt 5.9.7
OpenCV 3.2.0

​​https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows​​

Check the box [X]WITH_QT
Check the box [X]WITH_OPENGL
set Qt5_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5
Uncheck the box []ENABLE_PRECOMPILED_HEADERS
Then click configure again.
Set QT_MAKE_EXECUTABLE to D:\Qt\5.9\mingw53_32\bin\qmake.exe
Set Qt5Concurrent_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Concurrent
Set Qt5Core_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Core
Set Qt5Gui_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Gui
Set Qt5Test_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Test
Set Qt5Widgets_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Widgets
Set Qt5OpenGL_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5OpenGL
Set CMAKE_BUILD_TYPE to Release or RelWithDebInfo
Set OPENCV_VS_VERSIONINFO_SKIP=1
try this: in cmake check the box ENABLE_CXX11

cmake configure的过程提示ffmpeg下载失败,有效的解决方案参考如下文章：

修改 opencv\sources\3rdparty\ffmpeg下ffmpeg.cmake下载网址参考如上格式。

pro文件引用路径按自己的填写

INCLUDEPATH +=D:\OpenCV\opencv\build\include
LIBS += D:\OpenCV\mingw_build\bin\libopencv_core320.dll
LIBS += D:\OpenCV\mingw_build\bin\libopencv_highgui320.dll

测试程序如下

cv::Mat image=cv::imread(“D://workspace//testopencv//a.jpg”,1);
cv::namedWindow(“My image”);
cv::imshow(“My img”,image);

运行效果:
