**一、前言**

最近在学习点云库，由于刚刚入门，很多东西也不是很了解，如果大家有什么问题，都可以跟我沟通交流。除了通过博客交流外，欢迎你加入我的QQ群（326866692），一起交流有关于机器学习、深度学习、计算机视觉的内容。目前我并未确定具体的研究方向，所以现在处于广泛涉猎阶段，希望我们能够一起沟通。下图是我的群二维码：

今天要分享的是**PCL配置。**

**1、PCL简介**

**PCL（Point Cloud Library）**是在吸收了前人点云相关研究基础上建立起来的大型跨平台开源C++编程库，它实现了大量点云相关的通用算法和高效数据结构，涉及到点云获取、滤波、分割、配准、检索、特征提取、识别、追踪、曲面重建、可视化等。支持多种操作系统平台，可在Windows、Linux、Android、Mac OS X、部分嵌入式实时系统上运行。如果说OpenCV是2D信息获取与处理的结晶，那么PCL就在3D信息获取与处理上具有同等地位。

**2、软硬件环境**

**电脑：**Windows 10 64位

**编译器：**Visual Studio 2015

**PCL：** PCL 1.8.0 All-in-one InstallerMSVC2015 x64

下载地址：百度网盘：[https://pan.baidu.com/s/1Jm\_mGGp36u-nO4MLdt0PTQ][https_pan.baidu.com_s_1Jm_mGGp36u-nO4MLdt0PTQ]  提取码：jx5r

**注：**不同的电脑处理器位数和不同的编译器对应的PCL版本不同。

**二、PCL配置**

**1、PCL安装**

1.双击执行文件

2.点击下一步

3.点击我接受

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NodWl5aXhpbg_size_16_color_FFFFFF_t_70 1][]

4.添加所有用户（自由选择是否保存桌面图标）

5.选择安装路径并等待安装

**注意点：**

（1）尽量不要出现英文路径。

（2）最好保存在系统盘外的盘符。

（3）保证空间大于4.2G。

（4）**安装时，会提示安装OpenNI**，这个建议安装在PCL安装路径的3rdParty下的OpenNI2文件夹中。

（5）安装时间较长，请耐心等待。

**2、PCL配置**

### 1.打开VS2015，创建一个空项目 ###

**注：**去掉预编译头和SDL检查

**2.库目录配置**

依次选择 **调试-属性-VC++目录-库目录 **添加如下内容：

**注意：与自己安装路径有关。**

> E:\\Program Files\\PCL 1.8.1\\lib
