Semantic Segmentation of Point Clouds with PointNet++
Published: at 12:30 PMA practical guide to semantic segmentation of 3D point clouds with PointNet++. Learn why point clouds are hard for neural networks, how PointNet++ builds a hierarchical feature representation with sampling and grouping, and how to implement the key building blocks in PyTorch, with a worked example on the S3DIS indoor dataset.
Processing Point Clouds with PDAL
Published: at 10:00 AMA practical introduction to PDAL (Point Data Abstraction Library) for processing LiDAR point clouds. Learn the pipeline model, run filters from the command line and JSON, and integrate PDAL with Python and NumPy.
Gaussian Splatting vs. Traditional Photogrammetry
Published: at 10:00 AMA technical comparison between 3D Gaussian Splatting and traditional photogrammetry. Both techniques reconstruct 3D scenes from photographs, but differ fundamentally in their approach, strengths, and ideal use cases.
