如何將ITK與VTK連接？

我正在閱讀使用itk的DICOM系列，並將它們轉換爲VTK用於可視化目的。即使我設法在3種不同的方向（XY，XZ和YZ）下顯示DICOM系列，我甚至不能點擊窗口。當我點擊或嘗試更改查看的切片時，我的代碼會提供訪問衝突錯誤。我使用ImageViewer2來可視化切片。當我試圖找出錯誤是什麼時，打開一個名爲itkVTKImageExportBase.cxx的文件。線稱爲是：如何將ITK與VTK連接？

void VTKImageExportBase::UpdateInformationCallbackFunction(void* userData) 
{ 
    static_cast<VTKImageExportBase*> 
    (userData)->UpdateInformationCallback(); 
}

我的代碼如下：

typedef itk::VTKImageExport<ImageType> ExportFilterType; 
    ExportFilterType::Pointer itkExporter = ExportFilterType::New(); 
    itkExporter->SetInput(reader->GetOutput()); 


    // Create the vtkImageImport and connect it to the itk::VTKImageExport instance. 
    vtkImageImport* vtkImporter = vtkImageImport::New(); 
    ConnectPipelines(itkExporter, vtkImporter); 


    pViewerXY->SetInput(vtkImporter->GetOutput()); 
    pViewerXY->SetSlice(3); 
    pViewerXY->SetSliceOrientationToXY(); 
    pViewerXY->SetupInteractor(m_pVTKWindow_1); 
    pViewerXY->UpdateDisplayExtent(); 
    m_pVTKWindow_1->AddObserver(vtkCommand::KeyPressEvent, m_pVTKWindow_1_CallbackCommand); 
    m_pVTKWindow_1->Update(); 

    pViewerXZ->SetInput (vtkImporter->GetOutput()); 
    pViewerXZ->SetSliceOrientationToXZ(); 
    pViewerXZ->SetupInteractor(m_pVTKWindow_2); 
    pViewerXZ->UpdateDisplayExtent(); 
    m_pVTKWindow_2->AddObserver(vtkCommand::KeyPressEvent, m_pVTKWindow_2_CallbackCommand); 
    m_pVTKWindow_2->Update(); 

    pViewerYZ->SetInput (vtkImporter->GetOutput()); 
    pViewerYZ->SetSliceOrientationToYZ(); 
    pViewerYZ->SetupInteractor(m_pVTKWindow_3); 
    pViewerYZ->UpdateDisplayExtent(); 
    m_pVTKWindow_3->AddObserver(vtkCommand::KeyPressEvent, m_pVTKWindow_3_CallbackCommand); 
    m_pVTKWindow_3->Update();

pViewerXX窗口是imageviewer2對象而m_pVTKWindow_X指wxVTK對象在wxWidgets的GUI包使用。

可選：作爲給我的出口商和進口商在下面：

template <typename ITK_Exporter, typename VTK_Importer> 
void ConnectPipelines(ITK_Exporter exporter, VTK_Importer* importer) 
{ 
    importer->SetUpdateInformationCallback(exporter->GetUpdateInformationCallback()); 
    importer->SetPipelineModifiedCallback(exporter->GetPipelineModifiedCallback()); 
    importer->SetWholeExtentCallback(exporter->GetWholeExtentCallback()); 
    importer->SetSpacingCallback(exporter->GetSpacingCallback()); 
    importer->SetOriginCallback(exporter->GetOriginCallback()); 
    importer->SetScalarTypeCallback(exporter->GetScalarTypeCallback()); 
    importer->SetNumberOfComponentsCallback(exporter->GetNumberOfComponentsCallback()); 
    importer->SetPropagateUpdateExtentCallback(exporter->GetPropagateUpdateExtentCallback()); 
    importer->SetUpdateDataCallback(exporter->GetUpdateDataCallback()); 
    importer->SetDataExtentCallback(exporter->GetDataExtentCallback()); 
    importer->SetBufferPointerCallback(exporter->GetBufferPointerCallback()); 
    importer->SetCallbackUserData(exporter->GetCallbackUserData()); 
} 
/** 
* This function will connect the given vtkImageExport filter to 
* the given itk::VTKImageImport filter. 
*/ 
template <typename VTK_Exporter, typename ITK_Importer> 
void ConnectPipelines(VTK_Exporter* exporter, ITK_Importer importer) 
{ 
    importer->SetUpdateInformationCallback(exporter->GetUpdateInformationCallback()); 
    importer->SetPipelineModifiedCallback(exporter->GetPipelineModifiedCallback()); 
    importer->SetWholeExtentCallback(exporter->GetWholeExtentCallback()); 
    importer->SetSpacingCallback(exporter->GetSpacingCallback()); 
    importer->SetOriginCallback(exporter->GetOriginCallback()); 
    importer->SetScalarTypeCallback(exporter->GetScalarTypeCallback()); 
    importer->SetNumberOfComponentsCallback(exporter->GetNumberOfComponentsCallback()); 
    importer->SetPropagateUpdateExtentCallback(exporter->GetPropagateUpdateExtentCallback()); 
    importer->SetUpdateDataCallback(exporter->GetUpdateDataCallback()); 
    importer->SetDataExtentCallback(exporter->GetDataExtentCallback()); 
    importer->SetBufferPointerCallback(exporter->GetBufferPointerCallback()); 
    importer->SetCallbackUserData(exporter->GetCallbackUserData()); 
}
