计算机图形学的开始……

安装visual studio

下载visual studio 2013 安装即可，除了安装路径改到想安装的地方，其他保持默认即可。

mistake：

1. 若最终安装出现红色叹号，在控制面板中选择此程序，点击

更改

，选择repair，修复后重启电脑即可。

2. 若打开程序出现无法加载×××包或者无法新建项目，在控制面板中选择此程序，点击’更改’，选择repair，修复后重启电脑即可。

安装PCL-1.8.0-AllInOne-msvc2013-win32

版本说明：

本安装包由VS2013编译的32位PCL1.8.0rc1版本。仅可配置于VS2013，32位版本的程序上。

1.下载安装PCL

安装一键安装包时，将安装目录改为了”D:\software install\PCL 1.8.0”(自选)，注意：之后会弹出openni的安装界面，路径选择为”D:\software install\PCL 1.8.0\3rdParty\OpenNI2”。

2.配置环境变量

安装完成后，环境变量中会多出以下4个项目：





接着，我们自己还需要添加几个环境变量：

;D:\software install\PCL 1.8.0\bin;%PCL_ROOT%\3rdParty\FLANN\bin;%PCL_ROOT%\3rdParty\VTK\bin;%OPENNI2_REDIST%

3. copy pdb 文件

　　将下载的安装文件下的“PCL-1.8.0-AllInOne-msvc2013-win32-pdb”文件夹下的pdb文件copy到PCL的安装目录下的”PCL 1.8.0\bin”文件夹下。

4. 配置项目工程属性文件

（1）新建一个空项目，将项目设置成32位。

（2）在“视图 -> 其他窗口 ->属性管理器”中，打开属性管理器；

在Debug|win32下添加新项目属性表，取名PCL。

　　　　


双击PCL打开：

在PCL属性页 -> VC++目录 -> 包含目录 中添加如下目录：



在VC++目录 -> 库目录 设置如下：

同理配置release文件

attention

若以上配置出问题或嫌麻烦可直接调用安装包中已配置好的props文件，

将PCLDebug.props文件添加到Debug|Win32的属性表中，

将PCLRelease.props文件添加到Release|Win32的属性表中。即可。

（3）右键工程名，进入工程属性页，依次选中：

Configuration Properties(配置管理器)->C/C++->Preprocessor(预处理器)->Preprocessor Definitions(预处理定义) 中添加如下两项：

_SCL_SECURE_NO_WARNINGS
_CRT_SECURE_NO_WARNINGS

（4）项目环境目录配置

右键解决方案，属性，左侧配置属性–调试，右侧环境设置为：

PATH=$(PCL_ROOT)\bin;$(PCL_ROOT)\3rdParty\FLANN\bin;$(PCL_ROOT)\3rdParty\VTK\bin;$(PCL_ROOT)\Qhull\bin;$(PCL_ROOT)\3rdParty\OpenNI2\Tools;$(PATH)

4 测试代码

直接在工程中添加main.cpp文件后编译运行如下代码

#include <pcl/visualization/cloud_viewer.h>
#include <iostream>
#include <pcl/io/io.h>
#include <pcl/io/pcd_io.h>

int user_data;

void viewerOneOff(pcl::visualization::PCLVisualizer& viewer)
{
viewer.setBackgroundColor(1.0, 0.5, 1.0);
pcl::PointXYZ o;
o.x = 1.0;
o.y = 0;
o.z = 0;
viewer.addSphere(o, 0.25, "sphere", 0);
std::cout << "i only run once" << std::endl;

}

void viewerPsycho(pcl::visualization::PCLVisualizer& viewer)
{
static unsigned count = 0;
std::stringstream ss;
ss << "Once per viewer loop: " << count++;
viewer.removeShape("text", 0);
viewer.addText(ss.str(), 200, 300, "text", 0);

//FIXME: possible race condition here:
user_data++;
}

int main()
{
pcl::PointCloud<pcl::PointXYZRGBA>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZRGBA>);
pcl::io::loadPCDFile("D:/visual studio Projects/Project_PCL/my_point_cloud.pcd", *cloud);   //记得把路径换一下

pcl::visualization::CloudViewer viewer("Cloud Viewer");

//blocks until the cloud is actually rendered
viewer.showCloud(cloud);

//use the following functions to get access to the underlying more advanced/powerful
//PCLVisualizer

//This will only get called once
viewer.runOnVisualizationThreadOnce(viewerOneOff);

//This will get called once per visualization iteration
viewer.runOnVisualizationThread(viewerPsycho);
while (!viewer.wasStopped())
{
//you can also do cool processing here
//FIXME: Note that this is running in a separate thread from viewerPsycho
//and you should guard against race conditions yourself...
user_data++;
}
return 0;
}

5 添加my_point_cloud.pcd文件

在工程目录下D:/visual studio Projects/Project_PCL/(Project_PCL为我的工程名字)新建txt，添加一下数据后，修改名字和后缀即可。
