Easy Ways to Visualize 3D Point Clouds: Common Datasets & Formats in Python

LiDAR Point Cloud file formats like ply, pcd, npy, npz, hdf5, binary, las, laz, and txt are very common in popular point cloud datasets like Toronto3D, Trimble, Toyota PCD datasets, ScanNet, ShapeNet, Sun RGB-D, A2D2-Audi Autonomous Driving Dataset, KITTI, USGS 3DEP, ModelNet40, Semantic3D, ModelNet-C, ShapeNet-C, ScanObjectNN and many more. Such variety in data formats sometimes makes it inconvenient to handle point cloud datasets. Visualization is an important step in machine learning/computer vision. This many file formats don’t make point cloud visualization any easier. In this tutorial, I’ve talked about some easy ways to visualize the most common file formats we see in many popular point cloud datasets in computer vision using Open3D and PPTK python packages. I hope you find this video helpful.
The list of file formats covered here is below, with references to the popular datasets they are found in.
- ply (Toronto3D)
- pcd (Trimble, Toyota PCD datasets)
- npz, npy (ScanNet, ShapeNet, Sun RGB-D, A2D2-Audi Autonomous Driving Dataset)
- las, laz (USGS 3DEP)
- hdf5 (ModelNet-C, ShapeNet-C, ScanObjectNN)
- binary (KITTI)
- txt (ModelNet40, Semantic3D)

I couldn't install both, the open3d and pttk in my web-based cs50

i have .xyz fromat a lidar point cloud data how do i visualize that?

[@naveedarif3565]

hello, i need some help.

yup bro @@naveedarif3565

Animation and content is great but audio quality, accent and clarity of speech is really bad.

[@LightsCameraVision]

Noted. Thanks for the feedback. Didn’t have access to my regular mic, probably that’s the reason. Hope it’s not that bad. ✌️

@@LightsCameraVision accent is good enough bro, keep it up. But having a better mic is a nice boost to have.

[@m.alfatehmurkaz7247]

audio is ok though

pptk is taking too long. It doesn't show nothing.
