PCL 库使用资料

在 ubuntu18.04 上使用pcl记录

一、 安装

• 首先需要在 ubuntu 上安装c 库 sudo apt install libpcl-dev

dpkg -S pcl 查看包文件安装的位置，包括头文件和库文件，进到库文件路径下看，目前安装的是 pcl 1.8.1

/usr/include/pcl-1.8/pcl/sample_consensus/model_types.h #c 头文件

/usr/lib/x86_64-linux-gnu/ #c 库文件

lrwxrwxrwx 1 root root 23 9月  10  2018 libpcl_surface.so.1.8 -> libpcl_surface.so.1.8.1

• 点云python包 github 链接
  下载这个 repo， 按照 repo 给出的命令从源码生成 python binding 文件并安装包

python setup.py build_ext -i
python setup.py install

这一部会报错，ld找不到响应版本的链接库，ubuntu18.04 自动安装 pcl1.8.1 和vtk7.1，而setup.py 中是 vtk7.0, 需要把 setup.py 中的 vtk_version 改成7.1，再执行以上命令。

安装的结果

SENSETIME\yangchengwei@cn0214002744l:~/.local/lib/python3.6/site-packages/python_pcl-0.3.0rc1-py3.6-linux-x86_64.egg/pcl$ ls -1
__init__.py
_pcl.cpython-36m-x86_64-linux-gnu.so
_pcl.py
pcl_visualization.cpython-36m-x86_64-linux-gnu.so
pcl_visualization.py
__pycache__

PKG_INFO的结果如下：
Metadata-Version: 2.1
Name: python-pcl
Version: 0.3.0rc1

跑 example/simple_visualize.py 的结果能看到点云，并且 pcl_visualization tool 能进行旋转多角度观察(需要换个点云文件，可以用 examples/official/Surface/bun0.pcd)

二、过程日志
