写在前面：最近由于毕业论文三维点云相关项目需要，得学习PCL库相关知识，作为小白的我，配置PCL库和QT花了很长时间，为了造福后者，我讲下相应过程以及遇到的问题，以帮助小白少走弯路。后续会写一些PCL相关学习的文章，以记录学习过程并交流。

1、PCL 1.8.1配置

（1）安装

首先，下载PCL1.8.1库安装文件PCL-1.8.1-AllInOne-msvc2017-win64.exe ,pcl-1.8.1-pdb-msvc2017-win64.zip
这里要说明下，我是win10 64-bit系统，然后VS2017环境配置，所以请32位或者VS2015下载对应版本。这里还要说下，allinone版本是可以直接安装的（包含了很多第三方编译包，其中包括VTK，那为什么还要安装VTK呢，这是后话）

安装过程：
首先点击下载好的.exe文件，进行安装，点击如图所示add path，自动添加路径，然后点击下一步

再改掉安装路径，可以设置自己的安装路径（但是千万要注意，不要用中文安装路径，不要用中文，不要用中文，重要的话说三遍，后面VTK用CMAKE，cmake不识别中文，所以用英文）

随后再将如图所示的第三方安装包都勾选上

之后会等待一段时间安装，接下来安装第三方的库函数的时候记住要在自己选定的安装路径下安装　　比如我是安装在D盘下，所以当提示安装openni的时候我们需要给
opneni更改到自己选定的安装PCL的第三方库安装的路径下即，D：\Program Files\PCL1.8.1\3rdparty\OpenNI2，然后同意安装PrimerSense

然后就安装好了

安装过后可能会提示你路径太长，添加不了之类的错误提示，不用管，接下来配置就好了

（2）配置变量

由于我们勾选了Add PCL to system PATH for all users，安装好后，系统变量里会自动出现如下图所示的几个变量

然后还需要在系统变量的PATH变量中添加如下内容：%PCL_ROOT\bin;%PCL_ROOT%\3rdParty\VTK\bin;%PCL_ROOT\3rdParty\FLANN\bin;%OPENNI2_REDIST64%;%PCL_ROOT%\3rdParty\Qhull\bin;%PCL_ROOT%\3rdParty\OpenNI2\Tools
然后重启电脑使变量生效。
最后解压PCL-1.8.1-pdb-msvc2017-win64.zip，将里面的pdb文件全部复制到PCL安装路径下bin文件夹中；

(3)VS2017环境下配置PCL1.8.1

1. debug配置

新建一个空项目，将项目设置成64位。
切换属性管理器，在Debug|64下添加新项目属性表，取名PCL。
左侧点VC++目录，右侧包含目录添加：
D:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\Include;D:\Program Files\PCL 1.8.1\include\pcl-1.8;D:\Program Files\PCL 1.8.1\3rdParty\VTK\include\vtk-8.0;D:\Program Files\PCL 1.8.1\3rdParty\QHull\include;D:\Program Files\PCL 1.8.1\3rdParty\FLANN\include;D:\Program Files\PCL 1.8.1\3rdParty\Eigen\eigen3;D:\Program Files\PCL 1.8.1\3rdParty\Boost\include\boost-1_64;

右侧库目录添加：
D:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\Lib;D:\Program Files\PCL 1.8.1\3rdParty\VTK\lib;D:\Program Files\PCL 1.8.1\3rdParty\Qhull\lib;D:\Program Files\PCL 1.8.1\3rdParty\FLANN\lib;D:\Program Files\PCL 1.8.1\3rdParty\Boost\lib;D:\Program Files\PCL 1.8.1\lib;

左侧点链接器，再点输入，找到附加依赖项，添加如下(最后额外添加一个opengl32.lib的库，不然会报错，大概158个链接错误，评论区有出现过）：
vtknetcdf_c+±gd.lib;pcl_common_debug.lib;pcl_features_debug.lib;pcl_filters_debug.lib;pcl_io_ply_debug.lib;pcl_io_debug.lib;pcl_kdtree_debug.lib;pcl_keypoints_debug.lib;pcl_ml_debug.lib;pcl_octree_debug.lib;pcl_outofcore_debug.lib;pcl_people_debug.lib;pcl_recognition_debug.lib;pcl_registration_debug.lib;pcl_sample_consensus_debug.lib;pcl_search_debug.lib;pcl_segmentation_debug.lib;pcl_stereo_debug.lib;pcl_surface_debug.lib;pcl_tracking_debug.lib;pcl_visualization_debug.lib;libboost_atomic-vc141-mt-gd-1_64.lib;libboost_bzip2-vc141-mt-gd-1_64.lib;libboost_chrono-vc141-mt-gd-1_64.lib;libboost_container-vc141-mt-gd-1_64.lib;libboost_context-vc141-mt-gd-1_64.lib;libboost_coroutine-vc141-mt-gd-1_64.lib;libboost_date_time-vc141-mt-gd-1_64.lib;libboost_exception-vc141-mt-gd-1_64.lib;libboost_fiber-vc141-mt-gd-1_64.lib;libboost_filesystem-vc141-mt-gd-1_64.lib;libboost_graph-vc141-mt-gd-1_64.lib;libboost_graph_parallel-vc141-mt-gd-1_64.lib;libboost_iostreams-vc141-mt-gd-1_64.lib;libboost_locale-vc141-mt-gd-1_64.lib;libboost_log-vc141-mt-gd-1_64.lib;libboost_log_setup-vc141-mt-gd-1_64.lib;libboost_math_c99-vc141-mt-gd-1_64.lib;libboost_math_c99f-vc141-mt-gd-1_64.lib;libboost_math_c99l-vc141-mt-gd-1_64.lib;libboost_math_tr1-vc141-mt-gd-1_64.lib;libboost_math_tr1f-vc141-mt-gd-1_64.lib;libboost_math_tr1l-vc141-mt-gd-1_64.lib;libboost_mpi-vc141-mt-gd-1_64.lib;libboost_numpy3-vc141-mt-gd-1_64.lib;libboost_numpy-vc141-mt-gd-1_64.lib;libboost_prg_exec_monitor-vc141-mt-gd-1_64.lib;libboost_program_options-vc141-mt-gd-1_64.lib;libboost_python3-vc141-mt-gd-1_64.lib;libboost_python-vc141-mt-gd-1_64.lib;libboost_random-vc141-mt-gd-1_64.lib;libboost_regex-vc141-mt-gd-1_64.lib;libboost_serialization-vc141-mt-gd-1_64.lib;libboost_signals-vc141-mt-gd-1_64.lib;libboost_system-vc141-mt-gd-1_64.lib;libboost_test_exec_monitor-vc141-mt-gd-1_64.lib;libboost_thread-vc141-mt-gd-1_64.lib;libboost_timer-vc141-mt-gd-1_64.lib;libboost_type_erasure-vc141-mt-gd-1_64.lib;libboost_unit_test_framework-vc141-mt-gd-1_64.lib;libboost_wave-vc141-mt-gd-1_64.lib;libboost_wserialization-vc141-mt-gd-1_64.lib;libboost_zlib-vc141-mt-gd-1_64.lib;flann-gd.lib;flann_cpp-gd.lib;flann_cpp_s-gd.lib;flann_s-gd.lib;qhull_d.lib;qhullcpp_d.lib;qhullstatic_d.lib;qhullstatic_r_d.lib;qhull_p_d.lib;qhull_r_d.lib;vtkalglib-8.0-gd.lib;vtkChartsCore-8.0-gd.lib;vtkCommonColor-8.0-gd.lib;vtkCommonComputationalGeometry-8.0-gd.lib;vtkCommonCore-8.0-gd.lib;vtkCommonDataModel-8.0-gd.lib;vtkCommonExecutionModel-8.0-gd.lib;vtkCommonMath-8.0-gd.lib;vtkCommonMisc-8.0-gd.lib;vtkCommonSystem-8.0-gd.lib;vtkCommonTransforms-8.0-gd.lib;vtkDICOMParser-8.0-gd.lib;vtkDomainsChemistry-8.0-gd.lib;vtkexoIIc-8.0-gd.lib;vtkexpat-8.0-gd.lib;vtkFiltersAMR-8.0-gd.lib;vtkFiltersCore-8.0-gd.lib;vtkFiltersExtraction-8.0-gd.lib;vtkFiltersFlowPaths-8.0-gd.lib;vtkFiltersGeneral-8.0-gd.lib;vtkFiltersGeneric-8.0-gd.lib;vtkFiltersGeometry-8.0-gd.lib;vtkFiltersHybrid-8.0-gd.lib;vtkFiltersHyperTree-8.0-gd.lib;vtkFiltersImaging-8.0-gd.lib;vtkFiltersModeling-8.0-gd.lib;vtkFiltersParallel-8.0-gd.lib;vtkFiltersParallelImaging-8.0-gd.lib;vtkFiltersPoints-8.0-gd.lib;vtkFiltersProgrammable-8.0-gd.lib;vtkFiltersSelection-8.0-gd.lib;vtkFiltersSMP-8.0-gd.lib;vtkFiltersSources-8.0-gd.lib;vtkFiltersStatistics-8.0-gd.lib;vtkFiltersTexture-8.0-gd.lib;vtkFiltersTopology-8.0-gd.lib;vtkFiltersVerdict-8.0-gd.lib;vtkfreetype-8.0-gd.lib;vtkGeovisCore-8.0-gd.lib;vtkgl2ps-8.0-gd.lib;vtkhdf5-8.0-gd.lib;vtkhdf5_hl-8.0-gd.lib;vtkImagingColor-8.0-gd.lib;vtkImagingCore-8.0-gd.lib;vtkImagingFourier-8.0-gd.lib;vtkImagingGeneral-8.0-gd.lib;vtkImagingHybrid-8.0-gd.lib;vtkImagingMath-8.0-gd.lib;vtkImagingMorphological-8.0-gd.lib;vtkImagingSources-8.0-gd.lib;vtkImagingStatistics-8.0-gd.lib;vtkImagingStencil-8.0-gd.lib;vtkInfovisCore-8.0-gd.lib;vtkInfovisLayout-8.0-gd.lib;vtkInteractionImage-8.0-gd.lib;vtkInteractionStyle-8.0-gd.lib;vtkInteractionWidgets-8.0-gd.lib;vtkIOAMR-8.0-gd.lib;vtkIOCore-8.0-gd.lib;vtkIOEnSight-8.0-gd.lib;vtkIOExodus-8.0-gd.lib;vtkIOExport-8.0-gd.lib;vtkIOExportOpenGL-8.0-gd.lib;vtkIOGeometry-8.0-gd.lib;vtkIOImage-8.0-gd.lib;vtkIOImport-8.0-gd.lib;vtkIOInfovis-8.0-gd.lib;vtkIOLegacy-8.0-gd.lib;vtkIOLSDyna-8.0-gd.lib;vtkIOMINC-8.0-gd.lib;vtkIOMovie-8.0-gd.lib;vtkIONetCDF-8.0-gd.lib;vtkIOParallel-8.0-gd.lib;vtkIOParallelXML-8.0-gd.lib;vtkIOPLY-8.0-gd.lib;vtkIOSQL-8.0-gd.lib;vtkIOTecplotTable-8.0-gd.lib;vtkIOVideo-8.0-gd.lib;vtkIOXML-8.0-gd.lib;vtkIOXMLParser-8.0-gd.lib;vtkjpeg-8.0-gd.lib;vtkjsoncpp-8.0-gd.lib;vtklibharu-8.0-gd.lib;vtklibxml2-8.0-gd.lib;vtklz4-8.0-gd.lib;vtkmetaio-8.0-gd.lib;vtkNetCDF-8.0-gd.lib;vtkoggtheora-8.0-gd.lib;vtkParallelCore-8.0-gd.lib;vtkpng-8.0-gd.lib;vtkproj4-8.0-gd.lib;vtkRenderingAnnotation-8.0-gd.lib;vtkRenderingContext2D-8.0-gd.lib;vtkRenderingContextOpenGL-8.0-gd.lib;vtkRenderingCore-8.0-gd.lib;vtkRenderingFreeType-8.0-gd.lib;vtkRenderingGL2PS-8.0-gd.lib;vtkRenderingImage-8.0-gd.lib;vtkRenderingLabel-8.0-gd.lib;vtkRenderingLIC-8.0-gd.lib;vtkRenderingLOD-8.0-gd.lib;vtkRenderingOpenGL-8.0-gd.l

2、QT5.9.6下载安装

（1）qt5.9.6下载安装
首先进入科大镜像站（因为国外网站下载速度太慢，传送门：添加链接描述）下载qt5.9.6安装包

然后一步步安装下去，在下图这一步选择如图所示组件

然后一步步安装下去就可以了

（2）qt5.9.6VS中配置
首先点击工具–>拓展和更新–>联机–>搜索QT–>选择Qt Visual studio tools

然后点击左边的联机

在右边搜索框输入QT搜索Qt Visual Studio Tools，再下载完成

然后，关闭重启VS2017，然后就发现菜单栏多了QT VS Tools这一栏

然后点击Qt VS Tools,点击下图选项

如下图点击add

点击省略号选择安装的qt下的msvc2017_64的路径

这样qt在VS2017下的配置就完成了。

3、编译安装VTK

（1）下载VTK库文件
前文提到PCL安装包有编译好的VTK库，那为什么还要单独安装VTK呢？是由于预编译的vtk包并没有和qt进行编译得到QVTKWidget控件（该控件用来在qt上进行显示点云），因此需要下载VTK-8.0（必须是该版本，因为pcl-allinone包之前编译使用的是该版本
传送门：添加链接描述）使用CMAKE进行编译，或者点击我的百度网盘链接：添加链接描述 密码：kl3v，下载vtk8.0。
（2）编译VTK库文件
将下载好的VTK-8.0解压到3rdParty\下，在VTK-8.0里新建build文件夹，并清空PCL自带的VTK文件夹的内容，使用CMAKE进行相应的设置。
where is the source code 为你的VTK-8.0的路径
where to build the binaries 为VTK-8.0里build的路径
如图所示，第一次点击configure，等configure完成之后勾选Grouped和Advanced，进行以下设置：
BUILD下取消勾选BUILD_TESTING
CMAKE下CMAKE_INSTALL_PREFIX设置为你清空的VTK文件夹
VTK下勾选VTK_Group_Qt，VTK_RENDERING_BACKEND设置为OpenGL(这里一定要注意，否则pcl显示框会出错)
点击Add Entry，添加CMAKE_DEBUG_POSTFIX,Value设置为-gd(用来区别debug和release版本)
再次点击configure，如无error，点击Genrate。

进入到build目录下，使用VS打开VTK.sln
首先Debug x64下，右键ALL_BUILD生成，再右键INSTALL生成；
然后Release x64下，右键ALL_BUILD生成，再右键INSTALL生成；
将3rdParty\VTK\plugins\designer下的QVTKWidgetPlugin.dll拷贝到QT\5.7\msvc2015_64\plugins\designer下，这样Qt里面就有了QVtk的控件了。
然后不要忘了将上面的PCL VTK库文件目录改成自己命名或者生成的库文件夹名字，Debug和release都需要

至此PCL在windows下的环境已经搭配好了，可以选择重启让环境变量生效。
至此，大功告成。这个编译过程可以参考文章添加链接描述
