A note from Dr. Florent PouxThis is the engine I rebuilt three times before getting it right. The course gives you the final architecture without the dead ends — including the SAM-3D integration that took me months to wire up cleanly.

2. Technical Stack & Pedagogical Means

Software stack: Python and the standard 3D ecosystem (Open3D, Laspy, NumPy, PyTorch, CloudCompare, Meshroom — adapted to the course focus).
Hardware: any modern laptop (Windows, macOS, Linux). GPU recommended for deep learning modules.
Datasets: reference datasets and notebooks provided.
Infrastructure: proprietary LMS with 24/7 access, automated quizzes, progress tracking and digital course materials.
Modality: alternates theory and hands-on practice — code, real datasets, software use and shippable project deliverables.
Theory resources: video lessons, written handouts, curated research articles and PhD-level references.

3. Course Structure

Module	Title & Focus
M1	Foundations Course foreword, LiDAR sensing, environment setup.
M2	3D Maths & Tooling Maths, NumPy, Matplotlib, Open3D, datasets.
M3	Pre-processing & Sampling Point cloud in Python, voxel-grid sampling.
M4	Detection Algorithms RANSAC, DBSCAN, KD-Tree, PCA, bounding boxes.
M5	3D Python Apps Google Colab, n-order RANSAC, integrated workflows.
M6	Operational Workflows & SAM 3D Deep learning, photogrammetry, SAM 3D.

Why this structure, Dr. Florent PouxThe 6 modules are self-contained, so you can pick and choose. If you only have one evening, do the module that maps to your current project. The others will still be there next week.

M1 — Foundations

Course foreword, LiDAR sensing, environment setup.

Course foreword and system architecture.
LiDAR sensing fundamentals.
Anaconda environment setup.
Deep dive with Spyder IDE.
3D point cloud libraries.

M2 — 3D Maths & Tooling

Maths, NumPy, Matplotlib, Open3D, datasets.

Maths for 3D, made easy.
NumPy basics; Matplotlib for 3D; Open3D basics.
ADAS available 3D datasets.
Clustering and unsupervised techniques.
3D point clouds and representations.
Code and data access.

M3 — Pre-processing & Sampling

Point cloud in Python, voxel-grid sampling.

Point cloud in Python.

M4 — Detection Algorithms

RANSAC, DBSCAN, KD-Tree, PCA, bounding boxes.

RANSAC in-depth and 3D ground detection.
DBSCAN and HDBSCAN.
3D data structures and KD-Tree search.
PCA in-depth and PCA for feature extraction.
3D bounding-box extraction.
K-NN clustering.

Mid-course checkpoint, Dr. Florent PouxWhen you reach M4 — Detection Algorithms, stop and apply what you've learned to a dataset you actually care about. The back half of the course goes faster when the first half sits on a real example, not a toy one.

M5 — 3D Python Apps

Google Colab, n-order RANSAC, integrated workflows.

Introduction to Google Colab.
n-order RANSAC: domain transfer.
3D integrated workflows.
3D Python app.

M6 — Operational Workflows & SAM 3D

Deep learning, photogrammetry, SAM 3D.

Coder track: 3D deep learning.
Engineer track: point cloud processing.
On-site data: 3D photogrammetry.
3D object detection and operational workflow.
3D metrics and evaluation.
Segment Anything for 3D point clouds (full pipeline).
Course outro and engine roadmap.

Expert tip — Dr. Florent PouxSkip the Colab module if you have a local GPU. Keep going if you don't — Colab is still the fastest way to learn deep learning without buying hardware.

4. Assessment, Certificate & Grading

This is a free / open-source course. There is no project to defend and no oral examination. Evaluation is fully quiz-based via the LMS, and learners progress at their own pace.

Stage	Activity	Validation
During the course	End-of-module quiz (one per module).	Score ≥ 70 % per quiz.
End of the course	Final quiz covering the full course.	Score ≥ 80 %.

Conditions to obtain the completion certificate

Validate every end-of-module quiz with a score of 70 % or more.
Validate the final quiz with a score of 80 % or more.
Quizzes can be retaken without limit; the latest score is retained.

Grading scale

Pass: all quizzes ≥ 70 % and final ≥ 80 %.
Pass with Merit: average across all quizzes ≥ 85 %.
Pass with Distinction: average across all quizzes ≥ 92 %.

Successful learners receive the completion certificate and the Alumni digital badge.

Accessibility & disability: all evaluations can be adapted (extended time, alternative formats, oral or written substitution) on request to the disability referent howto@learngeodata.eu.
