A ground-up walkthrough of Puffin-World's Omni-Camera representation and physics propagation, with equations and interactive figures. 02 ·CNNs & Image Recognition·FREE·9 min read The Autonomous Driving Perception Stack from Scratch — What Cameras and LiDAR Each Bring to the Table How a self-driving car figures out what is around it, starting from sensor physics. We cover the complementary strengths of cameras and LiDAR, the bird's-eye-view grid where all sensors meet, occupancy grids grown by Bayesian updates, and the tug-of-war between safety requirements and compute budgets — no prior knowledge assumed.
