【ITK学习笔记】1.环境搭建

安装 VS2015 和 QT-5.7.1

• 下载并安装 VS2015 和 qt-opensource-windows-x86-msvc2015-5.7.1.exe
• 配置QT环境变量
  
• 安装QT-VS-TOOLS并选择Qt版本C:\Qt\Qt5.7.1\5.7\msvc2015_64
  
  

安装 VTK

• 文件目录如下，VTK-src放置源代码，VTK-bin放置CMake编译后的文件，VTK放置最终的文件,对应的下载网址 VTK
  
  
• CMake 编译
  
• Configure 一次
  
  BUILD_EXAMPLES：指明是否编译VTK中的例子。未激活可以减少编译时间，之后也可以再进行单独编译。此处我们置为OFF。
  BUILD_TESTING——指明是否编译VTK中的测试代码。未激活可以减少编译时间，之后也可以再进行单独编译。此处我们置为OFF。
  BUILD_SHARED_LIBS——指明是否创建共享库。如果激活，那么DLL或共享库将会被创建，这样之后生成的VTK应用程序将会比较小，可以节省不少空间；如果未激活，那么静态库将被创建.此处我们置为ON。
  
  CMAKE_INSTALL_PREFIX——VTK的生成路径,修改如下
  
  接下来的设置是有关QT的，搜索qt并勾选全部
  
  再次Configure后VTK_QT_VERSION 改为5
  
  再次Configure,后QT的位置会自动检测出来(改变QT环境变量后需要关机一下)
  
  这里Qt5WebKitWidgets_DIR找不到，我们去掉 Moudule_vtkGUISupportQtWebkit

Configure后没红点击Generate,然后点击 Open Project，还可以找到VTK.sln打开
  
• VS2015编译 ：ALL_BUILD-生成.没有问题后然后INSTALL-仅用于项目-仅生成INSTALL
  
  换成重新编译
  将QVTKWidgetPlugin.dll 复制到Qt 的designer中，对应目录如下
  
  
  这样VS2015中打开 Qt designer会多出 QVTKWidget
  
  *VTK测试:采用cmake建立工程，目录如下
  
  CMakeLists.txt内容

cmake_minimum_required(VERSION 2.8)
cmake_policy(SET CMP0020 NEW)
project(Cylinder)
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
add_executable(Cylinder Cylinder.cxx)
if(VTK_LIBRARIES)
  target_link_libraries(Cylinder ${VTK_LIBRARIES})
else()
  target_link_libraries(Cylinder vtkHybrid vtkWigets)
endif(VTK_LIBRARIES)

这里需要输入VTK_DIR(如果系统环境变量配置了D:\Kitware\VTK\VTK\debug\bin,这里会自动搜索出),他是包含UseVTK.cmake的文件夹

然后Configure没红后Generate没问题后 Open Project

打开VS2015在Cylinder.cxx中输入下面代码

#include "vtkCylinderSource.h"
#include "vtkPolyDataMapper.h"
#include "vtkActor.h"
#include "vtkRenderer.h"
#include "vtkRenderWindow.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkCamera.h"
#include "vtkProperty.h"
#include "vtkSmartPointer.h"

int main() {
    vtkSmartPointer<vtkCylinderSource> cylinder = vtkSmartPointer<vtkCylinderSource>::New();
    cylinder->SetResolution(8);

    vtkSmartPointer<vtkPolyDataMapper> cylinderMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
    cylinderMapper->SetInputConnection(cylinder->GetOutputPort());

    vtkSmartPointer<vtkActor> cylinderActor = vtkSmartPointer<vtkActor>::New();
    cylinderActor->SetMapper(cylinderMapper);
    cylinderActor->GetProperty()->SetColor(1.0000, 0.3882, 0.2784);
    cylinderActor->RotateX(30.0);
    cylinderActor->RotateY(-45.0);

    vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
    renderer->AddActor(cylinderActor);
    renderer->SetBackground(0, 0, 1);//RGB
    renderer->ResetCamera();
    renderer->GetActiveCamera()->Zoom(0.3);

    vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
    renderWindow->AddRenderer(renderer);
    renderWindow->SetSize(200, 200);

    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
    renderWindowInteractor->SetRenderWindow(renderWindow);
    renderWindowInteractor->Start();

    return 0;
}

ALL-BUILD-生成打开Cylinder.exe

安装ITK

从ITK 下载 到ITK_src,这里下的InsightToolkit-4.11.0版本,这里是 ITK examples，安装和上面一致，注意的是要勾上Moudule_ITKVtkGlue

• ITK测试
  

CMakeLists.cxx

cmake_minimum_required(VERSION 2.8)
cmake_policy(VERSION 2.8)
project(HelloWorld)

find_package(ITK REQUIRED)
include(${ITK_USE_FILE})
add_executable(HelloWorld HelloWorld.cxx)
target_link_libraries(HelloWorld ${ITK_LIBRARIES})

HelloWorld.cxx

#include"itkImage.h"
#include

int main(){
    typedef itk::Image short,3> ImageType;
    ImageType::Pointer image=ImageType::New();
    std::cout<<"hello world"<::endl;
    system("pause")；
    return 0;
}

结果

VTK，ITK混合测试

我们使用ITK读取图片然后VTK展示

CMakeLists.txt

cmake_minimum_required(VERSION 2.8)
cmake_policy(SET CMP0020 NEW)
project(ImageToVTKImageFilter)

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(ImageToVTKImageFilter  ImageToVTKImageFilter.cxx)
target_link_libraries(ImageToVTKImageFilter
  ${Glue}  ${VTK_LIBRARIES} ${ITK_LIBRARIES})

ImageToVTKImageFilter.cxx

#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkGDCMImageIO.h"
#include "itkImageToVTKImageFilter.h"
#include "vtkSmartPointer.h"
#include "vtkImageFlip.h"
#include "vtkImageViewer.h"
#include "vtkRenderWindowInteractor.h"

int main()

    typedef signed short PixelType;
    const unsigned int Dimension = 2;
    typedef itk::Image<PixelType, Dimension> ImageType;

    typedef itk::GDCMImageIO ImageIOType;
    ImageIOType::Pointer imageIO = ImageIOType::New();

    typedef itk::ImageFileReader<ImageType> ReaderType;
    ReaderType::Pointer reader = ReaderType::New();
    reader->SetFileName("E:/22");
    reader->SetImageIO(imageIO);
    reader->Update();

    typedef itk::ImageToVTKImageFilter<ImageType> ImageToVTKImageFilterType;
    ImageToVTKImageFilterType::Pointer itkToVtk = ImageToVTKImageFilterType::New();
    itkToVtk->SetInput(reader->GetOutput());
    itkToVtk->Update();

    vtkSmartPointer<vtkImageFlip> imageFlip = vtkSmartPointer<vtkImageFlip>::New();
    imageFlip->SetInputData(itkToVtk->GetOutput());
    imageFlip->SetFilteredAxes(1);
    imageFlip->Update();

    vtkSmartPointer<vtkRenderWindowInteractor> interactor =
        vtkSmartPointer<vtkRenderWindowInteractor>::New();

    vtkSmartPointer<vtkImageViewer> imageViewer = vtkSmartPointer<vtkImageViewer>::New();
    imageViewer->SetInputData(imageFlip->GetOutput());
    imageViewer->SetColorLevel(300);
    imageViewer->SetColorWindow(2000);
    imageViewer->SetupInteractor(interactor);
    imageViewer->Render();

    system("pause");

    return 0;
