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 <vtkSmartPointer.h>
#include "vtkImageViewer2.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkRenderer.h"
#include "vtkRenderWindow.h"
#include "vtkInteractorStyleImage.h"
#include "itkJPEGImageIOFactory.h"
#include "vtkImageMapper3D.h"
#include "vtkImageActor.h"
//#include "vtkJPEGReader.h"
#define JPEG_IMAGE_FILE_PATH "/home/jason/123.jpg"
//#include "itkRescaleIntensityImageFilter.h"
using namespace itk;
int main(int argc, char *argv[])
{
typedef itk::Image<itk::RGBPixel<unsigned char>, 2> ImageType;
typedef itk::ImageFileReader<ImageType> ReaderType;
typedef itk::ImageToVTKImageFilter<ImageType> ConnectorType;
itk::JPEGImageIOFactory::RegisterOneFactory();//注意这里的注册，用cmake管理可以不用
ReaderType::Pointer reader = ReaderType::New();
ConnectorType::Pointer connector = ConnectorType::New();
reader->SetFileName(JPEG_IMAGE_FILE_PATH);
connector->SetInput(reader->GetOutput());
vtkSmartPointer<vtkImageActor> actor =
vtkSmartPointer<vtkImageActor>::New();
//一定要注意下面的代码，不然可能是一片黑
#if VTK_MAJOR_VERSION <= 5
actor->SetInput(connector->GetOutput());
#else
connector->Update();
actor->GetMapper()->SetInputData(connector->GetOutput());
#endif
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
renderer->AddActor(actor);
renderer->ResetCamera();
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
vtkSmartPointer<vtkInteractorStyleImage> style =
vtkSmartPointer<vtkInteractorStyleImage>::New();
renderWindowInteractor->SetInteractorStyle(style);
renderWindowInteractor->SetRenderWindow(renderWindow);
renderWindowInteractor->Initialize();
renderWindowInteractor->Start();
return EXIT_SUCCESS;
}
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：
http://www.itk.org/Wiki/ITK/Examples
http://www.vtk.org/Wiki/VTK/Examples
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.
http://www.itk.org/Wiki/ITK/FAQ#NoFactoryException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：http://itk.org/ITKExamples/src/IO/ImageBase/RegisterIOFactories/Documentation.html
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 35
Error: no override found for 'vtkImageSliceMapper'.
Generic Warning: In /home/jason/program/VTK-6.2.0/Rendering/Core/vtkRenderWindow.cxx, line 40
Error: no override found for 'vtkRenderWindow'.
Generic Warning: In /home/jason/program/VTK-6.2.0/Rendering/Core/vtkRenderer.cxx, line 46
Error: 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 <vtkAutoInit.h>
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 43
vtkInteractorStyleSwitchBase (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。
