【PCL】mac下安装PCL的安装与配置

PCL

PCL官方文档

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，PCL是BSD授权方式，可以免费进行商业和学术应用。

通常在 windows 平台下安装 PCL 算是比较简单的,他的每一个版本都有一个 pcl 对应的的 AllInOne的一个安装的exe 软件 。或者也可以用 vcpkg 直接集成，但是mac下 安装的话更为简单。
PCL Download
github Download

第一步：安装homebrew

打开终端 输入

ruby -e "$(curl --insecure -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 

接下来等待安装完毕即可

第二步：使用homebrew安装pcl

也很简单，打开终端，输入：

brew install pcl

首先会安装PCL的相关依赖库，如vtk，glew等，最后安装pcl

第三步: PCL的编译

这一步是最麻烦的，由于之前更多地在Windows上进行开发，更没有接触过cmake，所以碰到了许多稀奇古怪的问题。

1. 在工程目录下（如Desktop/PCLtest/)新建文件CMakeLists.txt，在该文件中写入：

cmake_minimum_required(VERSION 3.0 FATAL_ERROR) # 选择cmake版本

project(PCLtest) # 给工程命名

find_package(PCL 1.4 REQUIRED COMPONENTS common io) # 使用find_package寻找指定版本PCL的指定模块，如果想导入全部模块，也可以写为 find_package(PCL REQUIRED) 

include_directories(${PCL_INCLUDE_DIRS})

link_directories(${PCL_LIBRARY_DIRS})

add_definitions(${PCL_DEFINITIONS})

add_executable(PCLtest main.cpp)

target_link_libraries(PCLtest ${PCL_LIBRARIES})

2. 在工程目录下新建文件main.cpp，并写入：

#include <iostream>
#include <pcl/io/pcd_io.h>
#include <pcl/point_types.h>
 
int
  main (int argc, char** argv)
{
  pcl::PointCloud<pcl::PointXYZ> cloud;
 
  // Fill in the cloud data
  cloud.width    = 5;
  cloud.height   = 1;
  cloud.is_dense = false;
  cloud.points.resize (cloud.width * cloud.height);
 
  for (size_t i = 0; i < cloud.points.size (); ++i)
  {
    cloud.points[i].x = 1024 * rand () / (RAND_MAX + 1.0f);
    cloud.points[i].y = 1024 * rand () / (RAND_MAX + 1.0f);
    cloud.points[i].z = 1024 * rand () / (RAND_MAX + 1.0f);
  }
 
  pcl::io::savePCDFileASCII ("test_pcd.pcd", cloud);
  std::cerr << "Saved " << cloud.points.size () << " data points to test_pcd.pcd." << std::endl;
 
  for (size_t i = 0; i < cloud.points.size (); ++i)
    std::cerr << "    " << cloud.points[i].x << " " << cloud.points[i].y << " " << cloud.points[i].z << std::endl;
 
  return (0);
}

3. 生成Cmake工程

在 CMakeLists.txt 同级目录下 (如Desktop/PCLtest)下 打开终端或者进入从家目录下进到这个目录

cmake -S . -B build

4. 打开终端，进行编译

同样 同级目录

cmake --build build

cmake后屏幕输出：

make后输出：

编译成功后，运行工程：

./pcd_write_test

运行结果：

使用CLion配置PCL

打开CLion新建工程，工程自动给出CMakeLists.txt和main.cpp，在对应文件中写入内容后运行即可

配置过程中出现的各种奇怪问题

1. 在编译前检查是否安装cmake，若没有安装，直接brew install cmake即可
2. 尽量使用gcc进行编译，若没有安装，直接brew install gcc（亲身验证，使用clang也可以。。。在编译过程中一直出现错误，病急乱投医，一度认为是编译器的问题）
3. 由于mac默认c编译器为clang，如果想使用gcc编译，参考：CMake 指定gcc编译版本

export CC=/usr/local/bin/gcc #你的gcc编译器路径
export CXX=/usr/local/bin/g++
cmake /path/to/your/project
make 

3. 整个过程中最烦心的错误出现了，搜索全网都没有找到与我出现相同错误的同学！！此时cmake是成功的，但是在make时提示出现错误：

Scanning dependencies of target pcd_write_test
[ 50%] Building CXX object CMakeFiles/pcd_write_test.dir/pcd_write.cpp.o
make[2]: *** No rule to make target `/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/Python', needed by `pcd_write_test'.  Stop.
make[1]: *** [CMakeFiles/pcd_write_test.dir/all] Error 2
make: *** [all] Error 2

解决方案（非常粗暴）找到文件夹/usr/local/Cellar/python/，发现里面只有一个文件夹3.7.4，直接将其文件夹名称改为3.7.3，问题解决文章来源地址https://www.toymoban.com/news/detail-861804.html
