Will it support for LiDAR data specifically LAS format and PCD format?

I think one can easily convert those data types to raw point clouds as N by C arrays. You are welcomed to post your converting code (link) here if you'd like to.

@charlesq34, will Pointnet will support for processing LAS files and PCD files?

One can easily convert PCD and LAS format to .txt format and then to hdf5 or similar using Python or Matlab. See https://stackoverflow.com/questions/44408141/how-to-convert-las-file-to-ply-file?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa for more info. Liblas library for python can also do the job for las https://www.liblas.org/tutorial/python.html or for pcd https://github.com/dimatura/pypcd

@niranjanreddy891 Hello, have you made any progress about the PCD files? I'm interested of the project, could you give me some advices?

I am focusing on raw format i.e., las/ laz files. :) On Tuesday, July 31, 2018, Jaiy notifications@github.com wrote:

Hi I am wondering how did you go about las/laz files. I have unlabelled asci files and las/laz files. I have converted them to hdf5 files should i sample them to 2048 randomly and what should I do about data labels.

@maryumjam were you able to prepare data from las/laz?

Read pcd file to arrays

import numpy as np 
import open3d as o3d
pcd = o3d.io.read_point_cloud("pointcloud_path.pcd")
out_arr = np.asarray(pcd.points)  

worked.
