【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>intmain (int argc, char** argv)
{pcl::PointCloud<pcl::PointXYZ> cloud;// Fill in the cloud datacloud.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
- 在编译前检查是否安装cmake,若没有安装,直接brew install cmake即可
- 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)
- 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
- 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
