qt + opencv

1.QT的下载和安装

   QT下载地址 http://download.qt.io/archive/qt/

   注意和vs的版本要相同。

   vs的话要下载和安装QT的vs插件 http://download.qt-project.org/official_releases/vsaddin/qt-vs-addin-1.1.11-opensource.exe

2.配置opencv

   在QTCreater里面修改.pro文件，配置opencv头文件和库文件如下，一定要注意格式！参照http://www.librehat.com/qt-5-2-vs2012-opencv-2-4-7-dev-environment-setup-tutorial/ 

  

INCLUDEPATH += E:/Documents/Opencv/opencv/build/include

win32:CONFIG(debug, debug|release): {
  LIBS += -LE:/Documents/Opencv/opencv/build/lib/Debug 
          -lopencv_core320d 
          -lopencv_highgui320d 
          -lopencv_imgcodecs320d 
          -lopencv_imgproc320d 
          -lopencv_video320d 
          -lopencv_videoio320d
}else:win32:CONFIG(release,debug|release):{
  LIBS += -LE:/Documents/Opencv/opencv/build/lib/Release 
          -lopencv_core320 
          -lopencv_highgui320 
          -lopencv_imgcodecs320 
          -lopencv_imgproc320 
          -lopencv_video320 
          -lopencv_videoio320 
}

3. 用vs时ui文件打不开,designed.exe,按照网上说的 把designed.exe文件夹里的一个名叫Qt5WebEngine.dll的dll改下名就可以了。
