Generating a ground plane for obstruction detection

This invention describes a system for a farming machine to automatically detect and avoid obstacles in a field. It uses a camera to capture 3D images of the ground, then identifies a flat 'ground plane' by finding a small, clear area and extending it across the entire image. Anything significantly rising above this calculated ground plane is flagged as an obstruction, prompting the machine to take evasive action.

Why it matters: Filed before advanced 3D scene understanding models were widely available. The claims describe a system that benefits from recent improvements in real-time AI for autonomous agricultural vehicles.
