Abstract
One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.
Claims18
An agricultural system comprising:
- a communication system that receives a prior information map that includes values of an agricultural characteristic corresponding to different geographic locations in a field;
- a geographic position sensor that detects a geographic location of an agricultural work machine;
- an in-situ sensor that detects a value indicative of a biomass characteristic corresponding to the geographic location and generates a sensor signal indicative of the value;
- a processing system that receives the sensor signal and is configured to identify, as a value of the biomass characteristic, a value of vegetation volume indicative of a volume of vegetation corresponding to the geographic location;
- a predictive model generator that generates a predictive agricultural model that models a relationship between the agricultural characteristic and the biomass characteristic based on a value of the agricultural characteristic in the prior information map at the geographic location and the value of the biomass characteristic detected by the in-situ sensor corresponding to the geographic location;
- and
- a predictive map generator that generates a functional predictive agricultural map of the field based on the values of the agricultural characteristic in the prior information map and based on the predictive agricultural model, the functional predictive agricultural map mapping predictive values of the biomass characteristic to the different geographic locations in the field.
A computer implemented method of generating a functional predictive agricultural map, comprising:
- receiving a prior information map that indicates values of an agricultural characteristic corresponding to different geographic locations in a field;
- detecting a geographic location of an agricultural work machine;
- detecting, with an in-situ sensor, a value indicative of a biomass characteristic corresponding to the geographic location and generating a sensor signal indicative of the value;
- processing the sensor signal to identify, as a value of the biomass characteristic, a value of vegetation volume indicative of a volume of vegetation corresponding to the geographic location;
- generating a predictive agricultural model that models a relationship between the agricultural characteristic and the biomass characteristic;
- and
- controlling a predictive map generator to generate the functional predictive agricultural map of the field that maps predictive values of the biomass characteristic to the different geographic locations in the field based on the values of the agricultural characteristic in the prior information map and the predictive agricultural model.
An agricultural system comprising:
- a communication system that receives a prior vegetative index map that indicates vegetative index values corresponding to different geographic locations in a field;
- a geographic position sensor that detects a geographic location of an agricultural work machine;
- an in-situ sensor that detects, as a biomass characteristic
- corresponding to the geographic location, a force used to drive a threshing rotor and generates a sensor signal indicative of the force used to drive the threshing rotor;
- a processing system that receives the sensor signal and is configured to identify, as a value of the biomass characteristic, a value of the force used to drive the threshing rotor;
- a predictive model generator that generates a predictive biomass model that models a relationship between the vegetative index values and values of the biomass characteristic based on a vegetative index value in the prior vegetative index map at the geographic location and the value of the biomass characteristic detected by the in-situ sensor corresponding to the geographic location;
- and
- a predictive map generator that generates a functional predictive biomass map of the field based on the vegetative index values in the prior vegetative index map and based on the predictive biomass model, the predictive biomass map mapping predictive biomass characteristic values to the different geographic locations in the field.
