VISION GUIDANCE SYSTEM USING DYNAMIC EDGE DETECTION

A row vision system modifies automated operation of a vehicle based on edges detected between surfaces in the environment in which the vehicle travels. The vehicle may be a farming vehicle (e.g., a tractor) that operates using automated steering to perform farming operations that track an edge formed by a row of field work completed next to the unworked field area. A row vision system may access images of the field ahead of the tractor and apply models that identify surface types and detect edges between the identified surfaces (e.g., between worked and unworked ground). Using the detected edges, the system determines navigation instructions that modify the automated steering (e.g., direction) to minimize the error between current and desired headings of the vehicle, enabling the tractor to track the row of crops, edge of field, or edge of field work completed.

Steering Method for an Agricultural Machine
20220350344 · 2022-11-03 ·

In a steering method for an agricultural machine, the agricultural machine is steered by track steering action independent of GNSS position data along an initial travel track in a working region until a headland adjoining the working region is reached at an exit point of the initial travel track. The agricultural machine is automatically steered by turn steering action, steering it based on an actual position determined based exclusively on GNSS position data, through the headland until an entry point of a target travel track in the working region is reached. The agricultural machine is steered by track steering action along the target travel track. The agricultural machine automatically detects a transition from a travel track of the working region into the headland and/or a transition from the headland into a travel track of the working region and switches accordingly between turn steering action and track steering action.
