How DJI Drones Dodge Obstacles without LiDAR (Engineering Explained)

Ever wonder how DJI drones effortlessly dodge obstacles without using radar or LiDAR? The secret is surprisingly similar to human eyes. 👀👇 In this video, we break down the fascinating engineering behind DJI's obstacle avoidance system. We explore how drones like the DJI Air 3 use "stereo vision" to transform flat 2D images into a fully navigable 3D world. You'll learn why DJI originally rejected expensive LiDAR, the genius math behind depth perception (disparity & triangulation), and how Artificial Intelligence is evolving to help drones not just see the world, but actually understand it.
