整合这三个，对于刚接触的新手我来说是一件很复杂的玩意，根本无从下手，网络整合的资源也不多，而且大部分是用cmake来管理项目，直接用过Qt的.pro文件来管理项目还是很少的，因此通过这次整合经历，记录出现问题，以便翻阅。

‍一 整合‍

通过Qtcreator创建Qt项目，会出现带有.pro文件的项目。

对于INCLUDE代码后面要加上自己的ITK和VTK的include文件夹，注意自己的在哪里，写正确位置，后面的LIBS一般在/usr/local/lib/目录下，注意把原来前面的lib换成-l，最前面要有空格，最后的.so要删除，连接用"\"符号。

test.cxx文件，代码如下：

#include "itkImageFileReader.h"#include "itkImageToVTKImageFilter.h"#define vtkRenderingCore_AUTOINIT 4(vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingFreeTypeOpenGL,vtkRenderingOpenGL)#define vtkRenderingVolume_AUTOINIT 1(vtkRenderingVolumeOpenGL)//注意以上两句 cmake管理可以不用#include

           actor =      vtkSmartPointer

如果使用cmake管理项目，只要在CMakeLists.txt写上

cmake_minimum_required(VERSION 2.4)project(test)find_package(ITK REQUIRED)include(${ITK_USE_FILE})    if (ITKVtkGlue_LOADED)        find_package(VTK REQUIRED)         include(${VTK_USE_FILE})    else()        find_package(ItkVtkGlue REQUIRED)        include(${ItkVtkGlue_USE_FILE})        set(Glue ItkVtkGlue)    endif() add_executable(test MACOSX_BUNDLE test.cxx)target_link_libraries(test  ${Glue}  ${VTK_LIBRARIES} ${ITK_LIBRARIES})

就可以了，记得改文件的名字，我的是test.cpp。

如果还有疑问可以上一下两个网站参考：

二 错误

1.之前除了两个与vnl有关的错误，具体报错忘记了，可以在.pro中添加

 -litkvnl-4.8 \ -litkvnl_algo-4.8

之前的文件已经添加了可以在最后面找到。

2.用一般的cmake管理项目时，ITK读取文件可以直接用

const char * ImageFileName = "";const unsigned int Dimension = 2;    typedef unsigned char PixelType;typedef itk::Image< PixelType, Dimension > ImageType;    typedef itk::ImageFileReader< ImageType >  ReaderType;ReaderType::Pointer reader = ReaderType::New();reader->SetFileName(ImageFileName );try{    reader->Update();    return EXIT_FAILURE;}catch( itk::ImageFileReaderException & ){    std::cout << "fail.\n" << std::endl;}

直接用采用Qt项目，用ITK来读取图片的时候，直接这样写会报错误

terminate called after throwing an instance of 'itk::ImageFileReaderException'  what():  /usr/local/include/ITK-4.8/itkImageFileReader.hxx:143: Could not create IO object for reading file /home/jason/program/ITK-4/Examples/Data/BrainT1Slice.png  There are no registered IO factories.  Please visit http://www.itk.org/Wiki/ITK/FAQ#NoFactoryException to diagnose the problem.

这里给出的解释是：

（1）如果是用cmake，需要在add_executable 或者 add_library之前添加

        include( ${ITK_USE_FILE} )

（2）如果没有使用cmake，必须对factories进行注册，可以使用

        XXXImageIOFactory::RegisterOneFactory(),XXX是类型

具体的代码：

    const char * metaImageFileName = "";    const char * pngFileName = "";        const unsigned int Dimension = 2;        typedef unsigned char PixelType;    typedef itk::Image< PixelType, Dimension > ImageType;        typedef itk::ImageFileReader< ImageType >  ReaderType;    ReaderType::Pointer reader = ReaderType::New();        typedef std::list< itk::LightObject::Pointer > RegisteredObjectsContainerType;            RegisteredObjectsContainerType registeredIOs =    itk::ObjectFactoryBase::CreateAllInstance( "itkImageIOBase" );    std::cout << "When CMake is not used to register the IO classes, there are\n"                << registeredIOs.size()                << " IO objects available to the ImageFileReader.\n" << std::endl;            std::cout << "When we try to read a MetaImage, we will ";    reader->SetFileName( metaImageFileName );    try    {        reader->Update();        return EXIT_FAILURE;    }    catch( itk::ImageFileReaderException & )    {        std::cout << "fail.\n" << std::endl;    }            std::cout << "After registering the MetaImageIO object, ";    itk::MetaImageIOFactory::RegisterOneFactory();        std::cout << "there are\n";    registeredIOs = itk::ObjectFactoryBase::CreateAllInstance( "itkImageIOBase" );    std::cout << registeredIOs.size()                << " IO objects available to the ImageFileReader.\n" << std::endl;        std::cout << "Now, when we try to read a MetaImage, we will ";    try    {        reader->Update();        std::cout << "succeed.\n" << std::endl;    }    catch( itk::ImageFileReaderException & error )    {        std::cerr << "Error: " << error << std::endl;        return EXIT_FAILURE;    }            std::cout << "Every format desired to be supported by the reader\n"                << "must be registered." << std::endl;    itk::PNGImageIOFactory::RegisterOneFactory();    reader->SetFileName( pngFileName );    try    {        reader->Update();    }    catch( itk::ExceptionObject & error )    {        std::cerr << "Error: " << error << std::endl;        return EXIT_FAILURE;    }

参考代码：

3.如果出现一下错误，找不到vtkImageSliceMapper，

Starting /home/jason/QtProjects/build-vtkQtTest-unknown-Debug/vtkQtTest...Generic Warning: In /home/jason/program/VTK-6.2.0/Rendering/Core/vtkImageSliceMapper.cxx, line 35Error: no override found for 'vtkImageSliceMapper'.Generic Warning: In /home/jason/program/VTK-6.2.0/Rendering/Core/vtkRenderWindow.cxx, line 40Error: no override found for 'vtkRenderWindow'.Generic Warning: In /home/jason/program/VTK-6.2.0/Rendering/Core/vtkRenderer.cxx, line 46Error: no override found for 'vtkRenderer'.

需要在#include任何有关vtk的头文件之前添加

#define vtkRenderingCore_AUTOINIT 4(vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingFreeTypeOpenGL,vtkRenderingOpenGL)#define vtkRenderingVolume_AUTOINIT 1(vtkRenderingVolumeOpenGL)

这两句，具体为什么还没有搞懂，如果有人知道希望能告知。

也可以使用代码

#include 
    
      VTK_MODULE_INIT(vtkRenderingOpenGL);
    

但是会出现其它警告

Starting /home/jason/QtProjects/build-vtkQtTest-unknown-Debug/vtkQtTest...Warning: In /home/jason/program/VTK-6.2.0/Rendering/Core/vtkInteractorStyleSwitchBase.cxx, line 43vtkInteractorStyleSwitchBase (0x1924210): Warning: Link to vtkInteractionStyle for default style selection.

原因还未分析。

如果是使用cmake管理，那么就不会有这个错误，在CMakeLists.txt里都定义好了，不会有问题。
