1、QT和VTK的版本有较重要的要求，我使用的是：QT-5.12.0，VTK-7.0；

2、VTK配置好后，在环境变量中添加：

PCL_ROOT   F:\PCL-1.8.0

%PCL_ROOT%\3rdParty\VTK\bin

3、将QVTKWidgetPlugin.dll复制到QT-install\5.12.0\msvc2015_64\plugins\designer文件夹下，正常情况下,Qt文件夹下就只有qaxwidget.dll和qquickwidget.dll

3、在Qt的ui中，添加widget，右键提升为QVTKWidget；

4、在.pro文件中添加：

INCLUDEPATH += F:/PCL/PCL-1.8.0/vtk7.0backup/include/vtk-7.0

LIBS += -LF:/PCL/PCL-1.8.0/vtk7.0backup/lib/Debug\

5、此时运行，会报错：

(1)、Error:no override found for "vtkRenderer"/"vtkImageMapper"

方法：在头文件中，添加相应的宏，对VTK模块初始化

#include <vtkAutoInit.h>

VTK_MODULE_INIT(vtkRenderingOpenGL2)

(2)Warning: In D:\VTK\VTK-6.3.0\Rendering\Core\vtkInteractorStyleSwitchBase.cxx, line 43  
vtkInteractorStyleSwitchBase (00000293C389B540): Warning: Link to vtkInteractionStyle for default style selection.  

方法：VTK_MODULE_INIT(vtkInteractionStyle)

（3）
ERROR: In F:\VTK\VTK-7.0\Rendering\Core\vtkTextMapper.cxx, line 543
vtkTextMapper (000001215D0AA770): Could not locate vtkTextRenderer object.

方法：VTK_MODULE_INIT(vtkRenderingFreeType)
