PCL点云数据库——第一篇（开发环境的搭建）

概述
点云数据库(Point Cloud Libary,PCL)是一个专门用来处理三维点云的跨平台开源库，支持Windows，Linux，Android,Mac OS X等平台。涉及点云处理得大量通用算法，包括点云获取、滤波、分割、配准、检索、特征提取、识别、追踪、曲面重建、可视化等基础模块，以及人体骨骼识别提取、动作跟踪识别等应用。
安装
目前笔者只使用Windows平台上的PCL点云开发，所以，这里只简述在Windows上的安装过程。
系统为WIN7
Visual Studio版本为VS2015

首先准备好安装需要的各种资源

这里注意，你可以根据自己的电脑版本选择对应的软件包，选择与VS版本一致的安装包。

按照默认安装PCL-1.8.0-ALLInOne-msvc2015-win64.exe就好，安装过程中会提醒是否自动添加环境变量，可以直接选择自动添加即可。
D:\PCL 1.8.0\bin;
D:\PCL 1.8.0\3rdParty\FLANN\bin;
D:\PCL 1.8.0\3rdParty\Qhull\bin;
D:\PCL 1.8.0\3rdParty\OpenNI2\Tools;
D:\PCL 1.8.0\3rdParty\VTK\bin;
安装成功后，新建VS2015控制台项目。

这里注意将开发环境改为×64位。接下来配置VS2015的环境，在属性管理器中的DEBUG×64右键选择属性，然后更改到VC++目录，更改其中的包含目录和库目录。


然后在
连接器的输入-附加依赖项中添加

这就完成了配置过程，将一下程序导入项目中，运行显示结果

#include 
#include 
#include 
int
main(int argc,char**argv)
{
    pcl::PointCloud cloud;
    // 创建点云
    cloud.width=5;
    cloud.height=1;
    cloud.is_dense=false;
    cloud.points.resize(cloud.width*cloud.height);
    for(size_t i=0;i

显示如下结果即配置成功。
