Win10+Qt6.4.2+VS2019+pcl1.12.1+vtk9.1.0环境配置（点云显示、处理）_qt vs2019 vtk pcl

1. 下载安装包

2. 安装vs2019

勾选使用C++的桌面开发，确认MSVC v142 2019 C++ x64/86生成工具和Windows 10 SDK选中，其余保持默认即可，若有其他开发需要可以自行选择。

3 安装Qt 6.4.2

首先需要注册一个Qt的账号，按照提示下一步

选择安装的目录并勾选Custom installation

选择Qt 6.4.2中的MSVC 2019 64-bit和Qt Debug Information Files，点击下一步，直到安装结束

3. 安装pcl 1.12.1+OpenNI2

双击exe进行安装，安装完成后，打开找到pcl安装路径下的3rdParty——>OpenNI2, 文件夹中只有msi文件，双击运行，卸载已安装的OpenNI2；再双击进行安装，安装路径选择当前OpenNI2的路径，安装完成后则会出现下列文件

将下载的pdb压缩包解压，拷贝其中的所有文件到pcl的bin目录下

4. 配置环境变量

打开环境变量，在系统变量中默认会设置好PCL_ROOT和OpenNI2_INCLUDE64/OPENNI2_LIB64/OPENNI2_REDIST64目录，确认与实际路径相符即可

双击打开Path，将如下的路径添加（根据自己的路径进行替换），配置完成后，重启电脑

5. 安装cmake 2.26

按照默认，进行安装即可

6. 编译 vtk 9.1.0

解压下载的vtk源代码压缩包，在其中创建一个新的文件夹build,打开cmake程序

将CMakeLists.txt拖入cmake窗体,将Where to build the binaries的路径选为刚才创建的build路径

点击Configure，选择Visual Studio 16 2019, x64,点击Finish

第一次Configure完成后，确认一下模块已经勾选或选择为YES，再次点击Configure

完成后，确认自动获取的Qt 版本以及Qt的各个模块路径是不是正确，再次点击Configure

完成后应该没有红色提示，如果有，再次确认红色内容，点击Configure直到没有红色，点击Generate

完成后，使用VS2019以管理权限启动，打开build下的VTK.sln

在VS中先对AllBuild进行Debug和Realese生成，再对INSTALL进行Debug和Relese的生成，正常情况下，所有的生成都会成功，失败数0

此时可以在刚才所选的VTK文件生成路径下，找到需要的文件，将其中的四个文件拷贝，替换pcl路径下自带的VTK中的文件

7. 安装VS 2019的Qt插件

在管理扩展中搜索qt，选择Qt Visual Studio Tools进行安装

安装完成后，进入Qt VS Tools——> Qt Version，选择Qt所在路径即可

8. 创建测试项目VS 2019 + Qt 6.4.2

1）创建项目Qt Widget Application

2）配置属性——>调试——>环境

3）配置VC++目录

包含目录（按照自己的对应路径进行替换）

库目录（按照自己的对应路径进行替换）

4）配置C/C++

预处理器——>预处理器定义

_CRT_SECURE_NO_WARNINGS
BOOST_ALL_NO_LIB
BOOST_USE_WINDOWS_H
NOMINMAX
_SCL_SECURE_NO_WARNINGS
_SILENCE_FPOS_SEEKPOS_DEPRECATION_WARNING

所有选项——>SDL 检查，选择否

5）配置链接器

输入——>附加依赖项（如下是Debug依赖项<以*d.lib结尾>，Realese只需要替换成对应lib即可）
