Abstract
A computer-implemented method includes obtaining a weed map of a field including a crop, the weed map representing weed plant locations on the field, identifying, based at least in part on the weed map, weed seed locations that represent presence of weed seeds on the field, and generating a control signal for a pre-emergence weed mitigation operation based on the weed seed locations.
Claims19
A computer-implemented method comprising:
- obtaining a weed plant map of a field including a crop, the weed plant map identifying a plurality of weed areas on the field,
- each weed area, of the plurality of weed areas, being defined in the weed plant map by a spatial boundary that identifies a relative position on the field of the weed area having weed plants;
- applying a movement model to the plurality of weed areas defined in the weed plant map, wherein the movement model represents movement of weed seeds from a first location on one or more weed plants to a second location in which the weed seeds are detached from the one or more weed plants and deposited on or in a ground surface of the field;
- based on applying the movement model to the weed plant map, generating a weed seed map that identifies one or more regions of the field having a number of weed seeds above a threshold;
- and
- generating a control signal for a pre-emergence weed mitigation operation based on the one or more regions identified in the weed seed map.
3 more elements
A computing system comprising:
- at least one processor;
- and
- memory storing instructions executable by the at least one processor, wherein the instructions, when executed, cause the computing system to:
- identify a weed plant map of a field including a crop, the weed plant map identifying a plurality of weed areas on the field,
- each weed area, of the plurality of weed areas, being defined in the weed plant map by a spatial boundary that identifies a relative position on the field of the weed area having weed plants;
- generate a weed seed map, that maps weed seed locations on the field, by
- applying a factor that represents movement of weed seeds from a first location on one or more weed plants to a second location in which the weed seeds are detached from the one or more weed plants and deposited on or in a ground surface of the field, and
- identifying one or more regions of the field having a number of weed seeds above a threshold;
- and
- generate a control signal for a pre-emergence weed mitigation operation based on the one or more regions identified in the weed seed map.

A control system for an agricultural machine, the control system comprising:
- a processor configured to:
- obtain a weed map of a field including a crop, the weed map identifying a plurality of weed areas on the field,
- each weed area, of the plurality of weed areas, being defined in the weed map by a spatial boundary that identifies a relative position on the field of the weed area having weed plants;
- apply a movement model to the plurality of weed areas defined in the weed map, wherein the movement model represents movement of weed seeds from a first location on one or more weed plants to a second location in which the weed seeds are detached from the one or more weed plants and deposited on or in a ground surface of the field, and wherein the movement model is based on at least one of:
- environment data representing an environment of the field,
- terrain data representing a terrain of the field, or
- machine data representing machine operating characteristics;
- identify, based on applying the movement model to the weed map, one or more regions of the field having a number of weed seeds above a threshold;
- and
- a controller configured to generate a control signal for a pre-emergence weed mitigation operation based on the one or more regions of the field.
