Point Cloud Feature Extraction: Complete Guide

This tutorial targets 3D Point Cloud Feature Extraction for developing an interactive Python Segmentation App. The goal is to develop an end-to-end system that can abstract complex point clouds with pertinent features. These features are then used by a thresholding mechanism to extract parts of the 3D Point Cloud.

Point Cloud Feature Extraction: Tutorial Brief

In this tutorial on 3D Point Cloud feature extraction and interactive Python app development. We are going to do something very powerful, by establishing an end-to-end point cloud processing workflow.

We are going to consider a LiDAR Point Cloud and extract several features, both based on principle component analysis (PCA) and also Relative Featuring Techniques.

After that, we will leverage a Python library for 3D data to create create an interactive thresholding method that can extract part of the point Cloud based on the features extracted, directly in a python-based 3D application.

Objectives of Point Cloud Feature Extraction

We have two primary purposes.

  • The first one, is to be able to have a workflow to label 3D data.
  • The second one is to have the ability to leverage 3D machine learning, 3D deep learning and create AI models.

So whenever you’re ready, let’s get started on what I got cooking for you.

My 3D Recommendation 🍉

Extracting features from 3D point clouds is a crucial step toward developing deep workflows. This is the base of 3D Machine Learning, 3D Deep Learning and many Artificial Intelligence and 3D Data Science Systems. Resources on the topic are sparse, and you can find some in the literature or in some of the work I published (E.g. : Voxel-based 3D Point Cloud Semantic Segmentation: Unsupervised Geometric and Relationship Featuring vs Deep Learning Methods). If you want to use it in your solutions, I recommend to check out the 3D Point Cloud Course or the 3D Object Detection Course.

If you want to get a tad more toward application-first or depth-first approaches, I curated several learning tracks and courses on this website to help you along your journey. Feel free to follow the ones that best suit your needs, and do not hesitate to reach out directly to me if you have any questions or if I can give you some advice on your current challenges!
