VS2015配合QVTKWidget显示点云数据

太过爱你忘了你带给我的痛 2022-01-11 04:15 623阅读 0赞

## 1、准备工作 ##

确保电脑上安装了Qt，Vs2015，以及Qt在VS中的插件，我的Qt版本是5.10

安装了PCL，路径中不要有空格，我的安装路径是**C:\\PCL1.8.1**，VTK放在**C:\\PCL1.8.1\\3rdParty\\VTK**

下载编译好的VTK8.0，[https://download.csdn.net/download/hb\_programmer/11248928  ][https_download.csdn.net_download_hb_programmer_11248928]

将**C:\\PCL1.8.1\\3rdParty\\VTK**目录删除，用这里下载的vtk替换，然后将**QVTKWidgetPlugin.dll**放到C:\\Qt\\Qt5.10.0\\5.10.0\\msvc2015\_64\\plugins\\designer

## 2、新建VS\_Qt\_GUI项目 ##

默认即可，进入项目，打开ui，在左侧最下方可以看到**QVTKWidget**，将其拖到界面中

## 3、首先在头文件中添加下面几行 ##

#ifndef INITIAL_OPENGL
    #define INITIAL_OPENGL
    #include <vtkAutoInit.h>
    VTK_MODULE_INIT(vtkRenderingOpenGL)
    VTK_MODULE_INIT(vtkInteractionStyle)
    #endif
    
    #include <vtkRenderWindow.h>

打开**项目属性**，按以下方式添加
