PCL.1在QT中显示点云

经过讨论终于知道是要干什么了：利用视差图生成点云

在QT中显示点云需要编译VTK获得dll

参考：blog.csdn.net/qq_27916741/article/details/79949986

cmake：Download | CMake

vtk8.0：https://gitlab.kitware.com/vtk/vtk/-/archive/v8.0.0/vtk-v8.0.0.zip

编译过程参考：VTK8.1 在 Qt5.9 环境下的配置、编译和安装_jepco1的博客-CSDN博客_qt vtk部分

注意版本选择在下面，如果不填的话默认是win32

取消勾选document，更改install目录，勾选QT ，更改Qt路径为msvc的

生成两个版本ALLBUILD以及INSTALL

这个地方绝对是血与泪的教训，大把的时间刷刷地没了！！！！！！！

生成debug版本的ALLBUILD和INSTALL后，把输出的install文件夹改名install-debug，新建一个install（空的）

然后在vs2015调整为release模式重新生成，再将install改名为install-release

如果不改的话，debug和release的生成同用一个目录，也就是说一个版本会直接覆盖另一个。

【谁能想到cmake编译生成的dll、lib都一个名字】

用于后续的目录 和 库的关联使用

将QTVTK*****.dll拷入qt目录下

注意在Qt5中改一下头文件  【更多解决办法：PCL1.8+Qt5+VS2013可视化点云_大作家佚名的博客-CSDN博客】

#include 

配置库目录：

../3rdparty/PCL1.8.1/lib;../3rdparty/PCL1.8.1/3rdParty/Boost/lib;../3rdparty/PCL1.8.1/3rdParty/FLANN/lib;../3rdparty/PCL1.8.1/3rdParty/Qhull/lib;../3rdparty/PCL1.8.1/3rdParty/VTK-debug/lib;../3rdparty/PCL1.8.1/3rdParty/OpenNI2/Lib;

生成的文件拷入VTK-debug/lib和 VTK-release/lib，两者都是相同的名字。。

同理，编译完成后也要注意分目录进行dll的拷入
