在QtCreator中将OpenCV 2.3与Qt一起使用 [英] Using OpenCV 2.3 with Qt in QtCreator

问题描述

由于OpenCV 2.3的发行版终于发布了，所以我想编译并安装此最新发行版到我的系统上.当我经常使用Qt和QtCreator时，我当然希望能够在我的Qt项目中使用它.我已经尝试了几种方法几个小时，但总是会出错:

as the release of OpenCV 2.3 is finally out, I wanted to compile and install this latest release on my system. As I often work with Qt and the QtCreator I of course wanted to be able to use it in my Qt projects. I've tried several methods now for some hours but always get errors:

首次尝试:使用WITH_QT编译OpenCV 2.3

首先，我想这样做，就像我对2.2发行版所做的一样.为此，我遵循了本指南: http://knowtheabc .wordpress.com/2011/02/25/windows-opencv-and-qt-creator/

First I wanted to do it just like I did with the 2.2 release which worked fine for me. For this I followed this guide: http://knowtheabc.wordpress.com/2011/02/25/windows-opencv-and-qt-creator/

• 下载了源代码
• 设置CMake，并告诉它创建MInGW Makefile，并在我的C:\ Qt ...路径中指定g++.exe，gcc.exe和qmake.exe的路径，检查WITH_QT并生成用于发布的Makefile.
• 使用mingw32-make和mingw32-make install
构建并将其安装在外壳中

• Downloaded the source code
• Set up CMake and told it to create MInGW Makefiles and specified the paths to the g++.exe, gcc.exe and qmake.exe in my C:\Qt... paths, checked WITH_QT and generated Makefiles for a release.
• Built and installed it in a shell using mingw32-make and mingw32-make install

成功完成此操作后，我只需要将路径添加到我的".pro"文件中，就可以构建一些使用OpenCV的漂亮软件了(回到我使用2.2版本时).基本上，最后一部分描述如下: http://knowtheabc.wordpress. com/2011/02/25/opencv-in-qt/

After this was completed successfully, I just needed to add the paths to my ".pro" file and was able to build some nice software that uses OpenCV (back at the time where I used the 2.2 release). Basically the last part is described here: http://knowtheabc.wordpress.com/2011/02/25/opencv-in-qt/

因此，我尝试对2.3版本进行相同的操作，该版本已成功编译，与旧版本一样.它甚至可以构建我的示例程序，但是一旦执行它，它就会再次关闭并返回:-1073741515

So I tried the same with the 2.3 release which compiled successfully just as with the old release. It even builds my example program but as soon as I execute it, it closes again and returns: -1073741515

第二种尝试:使用MinGW使用预构建的OpenCV超级包

由于第一种方法不起作用，因此我尝试使用预构建版本.尽管这些都没有启用WITH_QT，但我仍然想尝试.

As the first method didn't work I tried to use the pre-build versions. Though these don't have the WITH_QT enabled, I still wanted to try.

因此，我下载了超级包装，将其提取并放在了某个地方.然后，我想像以前一样做，然后将路径包括到include文件夹和dll添加到我的".pro"文件中:

So I downloaded the superpack, extracted and put it somewhere. I then wanted to do the same as I did before and added the paths to the include folder and the dlls to my ".pro" file:

INCLUDEPATH+= C:/workspace/opencv/OpenCV2.3/build/include
LIBS+= C:/workspace/opencv/OpenCV2.3/build/x64/mingw/bin/*.dll

作为编译器，我使用了当前Qt SDK随附的MinGW编译器.但这在构建时崩溃:

As compiler I used the MinGW compiler that comes with the current Qt SDK. But this crashes while building:

C:/workspace/opencv/OpenCV2.3/build/x64/mingw/bin/libopencv_calib3d230.dll: file not recognized: File format not recognized
collect2: ld returned 1 exit status
mingw32-make[1]: *** [release\CoinDetector.exe] Error 1
mingw32-make: *** [release] Error 2

第三次尝试:与第二次一样，但是使用了VC2008编译器

我也尝试使用Qt SDK随附的vc2008编译器进行相同的操作.因此，我选择了编译器，并修改了".pro"文件中的路径以供使用:

I tried the same thing with the vc2008 compiler that comes with the Qt SDK as well. So I selected the compiler and adapted the path in the ".pro" file to use:

LIBS+= C:/workspace/opencv/OpenCV2.3/build/x64/vc9/bin/*.dll

但这也会因无法读取dll的错误而崩溃:

But this also crashes with an error that it can't read the dll:

C:/workspace/opencv/OpenCV2.3/build/x64/vc9/bin/opencv_calib3d230.dll : fatal error LNK1107: Ungültige oder beschädigte Datei: Lesen bei 0x2F0 nicht möglich.

这是我的设置:

So here my settings:

• Win7 Professional x64
• 已安装最新的Qt SDK(4.7.3)
• OpenCV 2.3版本

有人知道这里可能有什么问题吗?希望获得帮助！

Does anybody have an idea what might be wrong here? Would be glad for any help!

推荐答案

我刚将QT 4.7.3与OpenCV2.3配合使用.不幸的是，我必须安装Microsoft的VC ++ 2008 Express Edition和CDB调试器(均为Microsoft的免费产品). 好消息是我现在可以在IDE，VS 2008和Qt Creator中为Opencv开发.

I just got my QT 4.7.3 to work with OpenCV2.3. Unfortunately I had to install VC++2008 Express Edition and the CDB Debugger from Microsoft (both are freebies from Microsoft). The good part is that I can now develop for Opencv in both IDE, VS 2008, and Qt Creator.

这些是我的.pro文件的设置:

These are the settings of my .pro file:

INCLUDEPATH += C:/OpenCV2.3/build/include
INCLUDEPATH += C:/OpenCV2.3/build/include/opencv

LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_calib3d230.lib
LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_contrib230.lib
LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_core230.lib
LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_features2d230.lib
LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_flann230.lib
LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_highgui230.lib
LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_imgproc230.lib
LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_objdetect230.lib
LIBS += C:/OpenCV2.3/build/x86/vc9/lib/opencv_video230.lib

请记住，在项目设置"中选择MSVC编译器

Remember, select the MSVC compiler in your Projects Settings

我尝试过不知道有多少种不同的方法可以使其与MinGW一起使用，但到目前为止，尚不正确. 我也使用Windows 7 64位...但是我正在开发32位，我想如果我使用x64库，可能会得到64位项目.

I have tried I don't know how many different approaches to make it work with MinGW, but not the right one so far. I'm also in Windows 7 64 bits...but I am developing for 32 bits, I suppose that if I use the x64 libraries I might get 64 bit projects to work.

祝你好运
