python 中的 3D 点云

Question

I am kind of new here:) Try to be concise, I am trying to pip install packages required for point cloud processing but I get these errors:

ERROR: Could not find a version that satisfies the requirement pclpy (from versions: none)  
ERROR: No matching distribution found for pclpy  
WARNING: You are using pip version 19.2.3, however version 19.3.1 is available.  
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Although I updated the pip I got the warning as well. Thanks

Hello and welcome to Stack Overflow!

As you can see in the pclpy official site, currently it does not work with Linux. Assuming you're using Linux, that explains the error you encountered.

For point cloud processing library in Python, you might want to have a look at Open3D . To install it, you just have to type pip install open3d in your terminal.

To read point cloud data in and write it out, you can just use a few line of codes:

import open3d as o3d

pcd = o3d.io.read_point_cloud('./input.pcd')
o3d.io.write_point_cloud('output.ply', pcd)

It's very easy to use and contains very good tutorial . Hope it helps!
