- 工程名称：FeatureLineExtractor
- 程序名称：Feature Line Extractor
- 运行环境：Windows x64
- 编译环境：Visual Studio 2017+PCL1.8.1+Qt5.10.1(msvc2017_64)
- Qt+Visual Studio环境配置说明
(1) 安装Qt
Qt编译器版本必须为系统相应位数的msvc编译器，msvc版本必须与Visual Studio编译器版本一致。
(2) 在Visual Studio中安装Qt插件
在Visual Studio中打开工具-扩展和更新，在联机-Visual Studio Marketplace中搜索并安装插件：Qt Visual Studio Tools
- PCL环境配置说明
(1) 下载PCL安装程序和PDB包
GitHub地址：https://github.com/PointCloudLibrary/pcl/releases
分别下载相应系统位数和版本的PCL安装程序和PDB包，两者系统位数（32/64）、PCL版本号和msvc版本号必须相同，msvc版本号必须与Visual Studio编译器版本一致。
(2) 安装PCL
运行PCL-x.x.x-AllInOne-msvcxxxx-winxx.exe，选择合适的环境变量配置，选择安装路径（安装路径在下文简称为%pcl_path%），之后第三方库的安装路径不用改变，都安装于%pcl_path%\3rdParty\目录之下即可。
(3) 安装PDB包
解压pcl-x.x.x-pdb-msvcxxxx-winxx.zip，将里面所有的pdb文件拷贝到%pcl_path%\bin目录下。
(4) 配置第三方PCL库环境变量
在系统变量Pah中添加环境变量：%PCL_ROOT%\bin;%PCL_ROOT%\3rdParty\FLANN\bin;%PCL_ROOT%\3rdParty\VTK\bin;%PCL_ROOT%\Qhull\bin;%PCL_ROOT%\3rdParty\OpenNI2\Tools
重启系统使配置生效。
- Visual Studio工程的配置
(1) Visual Studio解决方案类型为Visual C++-Qt-Qt GUI Application。
(2) 在项目属性-VC++目录-可执行文件目录中添加以下位置： ·Debug和Release配置相同。 %pcl_path%\bin %pcl_path%\3rdParty\Boost\lib %pcl_path%\3rdParty\FLANN\bin %pcl_path%\3rdParty\Qhull\bin %pcl_path%\3rdParty\VTK\bin
(3) 在项目属性-VC++目录-包含目录中添加以下位置： ·Debug和Release配置相同。 %pcl_path%\include\pcl-1.8 %pcl_path%\3rdParty\Boost\include\boost-1_64 %pcl_path%\3rdParty\Qhull\include %pcl_path%\3rdParty\Eigen\eigen3 %pcl_path%\3rdParty\VTK\include\vtk-8.0 %pcl_path%\3rdParty\FLANN\include
(4) 在项目属性-VC++目录-库目录中添加以下位置： ·Debug和Release配置相同。 %pcl_path%\lib %pcl_path%\3rdParty\Boost\lib %pcl_path%\3rdParty\VTK\lib %pcl_path%\3rdParty\FLANN\lib %pcl_path%\3rdParty\Qhull\lib
(5) 在项目属性-链接器-输入-附加依赖项中添加以下位置： ·Debug配置： pcl_common_debug.lib pcl_features_debug.lib pcl_filters_debug.lib pcl_io_debug.lib pcl_io_ply_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_parallel-vc141-mt-gd-1_64.lib libboost_graph-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 vtkzlib-8.0-gd.lib vtkViewsContext2D-8.0-gd.lib vtkhdf5_hl-8.0-gd.lib vtkFiltersProgrammable-8.0-gd.lib vtkIOMovie-8.0-gd.lib vtkexpat-8.0-gd.lib vtkRenderingLOD-8.0-gd.lib vtkIOPLY-8.0-gd.lib vtkpng-8.0-gd.lib vtkIOVideo-8.0-gd.lib vtkRenderingImage-8.0-gd.lib vtkFiltersVerdict-8.0-gd.lib vtkjpeg-8.0-gd.lib vtkInteractionImage-8.0-gd.lib vtkverdict-8.0-gd.lib vtkoggtheora-8.0-gd.lib vtkImagingStatistics-8.0-gd.lib vtkCommonSystem-8.0-gd.lib vtkFiltersParallelImaging-8.0-gd.lib vtkFiltersTexture-8.0-gd.lib vtkCommonMisc-8.0-gd.lib vtkCommonMath-8.0-gd.lib vtkFiltersSelection-8.0-gd.lib vtkImagingFourier-8.0-gd.lib vtkIOXMLParser-8.0-gd.lib vtkproj4-8.0-gd.lib vtkalglib-8.0-gd.lib vtktiff-8.0-gd.lib vtksqlite-8.0-gd.lib vtkImagingSources-8.0-gd.lib vtkCommonTransforms-8.0-gd.lib vtkImagingMath-8.0-gd.lib vtkFiltersGeneric-8.0-gd.lib vtkexoIIc-8.0-gd.lib vtkfreetype-8.0-gd.lib vtkImagingColor-8.0-gd.lib vtknetcdf_c++-gd.lib vtkNetCDF-8.0-gd.lib vtkFiltersImaging-8.0-gd.lib vtkFiltersHyperTree-8.0-gd.lib vtkImagingMorphological-8.0-gd.lib vtkImagingStencil-8.0-gd.lib vtkRenderingFreeType-8.0-gd.lib vtkCommonColor-8.0-gd.lib vtkjsoncpp-8.0-gd.lib vtkRenderingContext2D-8.0-gd.lib vtkFiltersAMR-8.0-gd.lib vtkRenderingContextOpenGL-8.0-gd.lib vtkIOParallelXML-8.0-gd.lib vtkViewsCore-8.0-gd.lib vtkImagingHybrid-8.0-gd.lib vtkIOExport-8.0-gd.lib vtkRenderingVolumeOpenGL-8.0-gd.lib vtkIOImport-8.0-gd.lib vtkDomainsChemistry-8.0-gd.lib vtkInteractionStyle-8.0-gd.lib vtkCommonComputationalGeometry-8.0-gd.lib vtkDICOMParser-8.0-gd.lib vtklibxml2-8.0-gd.lib vtkIOMINC-8.0-gd.lib vtkIOSQL-8.0-gd.lib vtkFiltersModeling-8.0-gd.lib vtkParallelCore-8.0-gd.lib vtkIOAMR-8.0-gd.lib vtkGeovisCore-8.0-gd.lib vtksys-8.0-gd.lib vtkIOEnSight-8.0-gd.lib vtkImagingGeneral-8.0-gd.lib vtkFiltersFlowPaths-8.0-gd.lib vtkIOLSDyna-8.0-gd.lib vtkFiltersSMP-8.0-gd.lib vtkIOParallel-8.0-gd.lib vtkFiltersGeometry-8.0-gd.lib vtkInfovisLayout-8.0-gd.lib vtkIOCore-8.0-gd.lib vtkFiltersSources-8.0-gd.lib vtkIOLegacy-8.0-gd.lib vtkFiltersHybrid-8.0-gd.lib vtkIONetCDF-8.0-gd.lib vtkFiltersExtraction-8.0-gd.lib vtkFiltersParallel-8.0-gd.lib vtkRenderingLabel-8.0-gd.lib vtkIOInfovis-8.0-gd.lib vtkRenderingAnnotation-8.0-gd.lib vtkImagingCore-8.0-gd.lib vtkCommonExecutionModel-8.0-gd.lib vtkhdf5-8.0-gd.lib vtkViewsInfovis-8.0-gd.lib vtkIOGeometry-8.0-gd.lib vtkmetaio-8.0-gd.lib vtkIOImage-8.0-gd.lib vtkIOXML-8.0-gd.lib vtkIOExodus-8.0-gd.lib vtkRenderingVolume-8.0-gd.lib vtkChartsCore-8.0-gd.lib vtkFiltersStatistics-8.0-gd.lib vtkInfovisCore-8.0-gd.lib vtkRenderingCore-8.0-gd.lib vtkInteractionWidgets-8.0-gd.lib vtkRenderingOpenGL-8.0-gd.lib vtkFiltersGeneral-8.0-gd.lib vtkFiltersCore-8.0-gd.lib vtkCommonDataModel-8.0-gd.lib vtkCommonCore-8.0-gd.lib flann_cpp_s-gd.lib qhullstatic_d.lib
