Assignee: DEERE & COMPANY
Field: Other special machines (Mechanical engineering)
Classification: CPC A  G | IPC A  G

Claim 0:
1. An agricultural machine that travels across a field in a direction of travel, comprising:
a material reservoir;
a boom having an elongate axis that is transverse to an elongate axis of the agricultural machine;
a plurality of controllable valves mounted across the boom;
a plurality of optical sensors that each capture images of a portion of the field ahead of the plurality of controllable valves in the direction of travel;
a calibration system that, for each given optical sensor, generates a transform corresponding to the given optical sensor to apply to a received image, received by the given optical sensor to identify a location on the field corresponding to a position in the received image;
a pump that pumps material from the material reservoir to the plurality of controllable valves;
a target identification system that identifies a target in the received image and applies the transform to the received image to identify a location on the field corresponding to the target; and
a valve controller that generates a valve control signal to control the plurality of controllable valves to apply the material to the target.
