[Part 4] 在Windows 10上源码编译PCL 1.8.1支持VTK和QT,可视化三维点云

本文首发于个人博客https://kezunlin.me/post/2d809f92/,欢迎阅读!

Part-4: Compile pcl with vtk qt5 support from source on windows.

Series

Guide

Tips

we'd better to use SSD to compile source code instead HDD. So put source code in C folder on windows.
use multiple processor to compile with /MP options.

install vs2015

skip.

configure vs2015 with admin

when we compile pcl by vs2015 and install to folder C:/Program Files/PCL , we need administrative priviledges.
follow steps:

cmd+r 
regeidt
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

# new string entry
key: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe
value: ~ RUNASADMIN

vs2015 regedit for runasadmin

install qt

install qt to path C:\Qt\Qt5.7.1

add the following to system path.

C:\Qt\Qt5.7.1\5.7\msvc2015_64\bin
C:\Qt\Qt5.7.1\Tools\QtCreator\bin

install qt-vs-tools

online install by vs2015

start vs2015, install Qt Visual Sutido Tools by:

Tools---> Extensions and Update... ---> online search qt ---> install Qt Visual Sutido Tools ---> OK

restart vs2015 and new menu Qt VS Tools will be added to VS Main menu.

offline install by vsix

wget https://mirrors.tuna.tsinghua.edu.cn/qt/archive/vsaddin/qt-vs-tools-msvc2015-2.1.1.vsix

double click qt-vs-tools-msvc2015-2.1.1.vsix and install.

configure qt for vs

follow steps

Qt VS Tools ---> Qt Options ---> Add name and path

Add qt path for vs2015 so that we can find %PATH%\bin\qmake.exe

Name: Qt 5.7.1
Path: C:\Qt\Qt5.7.1\5.7\msvc2015_64\

qt options

new qt project from vs

start vs2015, and new Qt Gui Application.

new qt gui application

Compile and run first qt program.
Success.

install pcl third parties

install pcl by installer

install pcl to C:\Program Files\PCL 1.8.1\

choose to install OpenNI2 to C:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\

this process will add 4 system env.

PCL_ROOT          C:\Program Files\PCL 1.8.1
OPENNI2_INCLUDE64 C:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\Include\
OPENNI2_LIB64     C:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\Lib\ 
OPENNI2_REDIST64  C:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\Redist\

configure env

add env to Path.

%PCL_ROOT\bin
%PCL_ROOT%\3rdParty\FLANN\bin
%PCL_ROOT%\3rdParty\OpenNI2\Redist
%PCL_ROOT%\3rdParty\OpenNI2\Tools
%PCL_ROOT%\3rdParty\Qhull\bin
%PCL_ROOT%\3rdParty\VTK\bin

copy winpap package

copy winpap to C:\Program Files\PCL 1.8.1\3rdParty\, and 3rdParty folder looks like this:

$ ls -al

compile vtk

download vtk and data

wget https://www.vtk.org/files/release/8.1/VTK-8.1.0.zip
wget https://www.vtk.org/files/release/8.1/VTKData-8.1.0.zip

configure source

we need to compile vtk to replace C:\Program Files\PCL 1.8.1\3rdParty\VTK\

cd c:/compile/VTK-8.1.0
mkdir build && cd build 
cmake-gui ..

configure generator to Visual Studio 14 2015 Win64 with options

VTK_Group_Qt  ON
VTK_QT_VERSION     5  # by default 4
VTK_RENDERING_BACKEND OpenGL2 # by default OpenGL
Qt5_DIR  C:/Qt/Qt5.7.1/5.7/msvc2015_64/lib/cmake/Qt5

CMAKE_INSTALL_PREFIX  C:/Program Files/VTK  # by default
BUILD_SHARED_LIBS  ON
CMAKE_CONFIGURATION_TYPES Release # Release
CMAKE_CXX_FLAGS_RELEASE /MD /O2 /Ob2 /DNDEBUG /MP # for multiple processor
unzip VTKData-8.1.0.zip and copy MD5 to VTK-8.1.0/build/ExternalData/Objects/MD5

(1) With VTK = 8.1.0:

VTK_Group_Qt  ON

configure again, and then QT_QMAKE_EXECUTABLE and VTK_QT_VERSION will appear.

(2) we need to change VTK_QT_VERSION from 4 to 5.

VTK_QT_VERSION     5  # by default 4

(3) change VTK_RENDERING_BACKEND from OpenGL to OpenGL2.

VTK_RENDERING_BACKEND OpenGL2 # by default OpenGL

(4) set install path C:\Program Files\VTK\

CMAKE_INSTALL_PREFIX  C:/Program Files/VTK  
we need write privileges to install to C:\Program Files\VTK\

otherwise, when we install, error will occur:

1>  -- Install configuration: "Release"
1>  CMake Error at cmake_install.cmake:36 (file):
1>    file cannot create directory: C:/Program Files/VTK/lib/cmake/vtk-8.0.
1>    Maybe need administrative privileges.

(5) we should also notice BUILD_SHARED_LIBS


BUILD_SHARED_LIBS  ON

(6) add /MP for multiple processor compile

CMAKE_CXX_FLAGS_RELEASE /MD /O2 /Ob2 /DNDEBUG /MP # for multiple processor

# only exist for VTK
CMAKE_CXX_MP_FLAG ON
CMAKE_CXX_MP_NUM_PROCESSORS 8

(7) Configure and warning will occur

CMake Deprecation Warning at ThirdParty/libproj4/vtklibproj4/cmake/policies.cmake:2 (cmake_policy):
  The OLD behavior for policy CMP0022 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.
Call Stack (most recent call first):
  ThirdParty/libproj4/vtklibproj4/CMakeLists.txt:43 (include)

We can omit this warning.

compile

If everything goes well, then generate VTK.sln.

Open VTK.sln in vs2015 and build with Release X64.

NOTICE: this build process will take about 10 minutes.(10:35-10:45)

... waiting about 10 minutes ...
========== 生成: 成功 127 个,失败 0 个,最新 0 个,跳过 0 个 ==========

========== 生成: 成功 192 个,失败 0 个,最新 4 个,跳过 0 个 ==========

install vtk

choose INSTALL and generate , and VTK will be installed to C:\Program Files\VTK\.

Notice for QVTKWidgetPlugin and copy dll and lib to C:\Program Files\VTK\.

  • dll: copy C:\compile\VTK-8.1.0\build\bin\Release\QVTKWidgetPlugin.dll to C:\Program Files\VTK\bin\QVTKWidgetPlugin.dll
  • lib: copy C:\compile\VTK-8.1.0\build\lib\Release\QVTKWidgetPlugin.libto C:\Program Files\VTK\lib\QVTKWidgetPlugin.lib

we should also notice that dll has been copied to C:\Program Files\VTK\plugins\designer\QVTKWidgetPlugin.dll

copy vtk to pcl

copy vtk from C:\Program Files\VTK\ to C:/Program Files/PCL 1.8.1/3rdParty/VTK to replace old one.

install QVTKWidgetPlugin

copy C:\Program Files\VTK\plugins\designer\QVTKWidgetPlugin.dll to
C:\Qt\Qt5.7.1\5.7\msvc2015_64\plugins\designer

start vs2015 again, view mainwindow.ui in Qt Designer.

Now QVTKWidget will occur.

qvtkwidget_in_qt_designer

compile pcl

install pcl to get 3rdparty libraries and copy to proper folder.

install pcl

by default install need administrator privilidges to write to C:/Program Files/PCL/.

choose INSTALL and generate , and PCL will be installed to C:/Program Files/PCL.

Example

pcl only
