Abstract
An information map is obtained by an agricultural system. The information map maps characteristic values at different geographic locations in a worksite. An in-situ sensor detects values of a characteristic as a mobile machine operates at the worksite. A predictive map generator generates a predictive map that maps predictive values of the characteristic detected by the in-situ sensor at different geographic locations in the worksite based on a relationship between the values of the characteristic in the information map and the values of the characteristic detected by the in-situ sensor. The predictive map can be output and used in automated machine control.
Claims20
An agricultural spraying system comprising:
- a communication system configured to receive an information map that includes values of a characteristic corresponding to different geographic locations in a worksite;
- an in-situ soil moisture sensor configured to detect a value of soil moisture corresponding to a geographic location in the worksite;
- a predictive model generator configured to generate a predictive model indicative of a relationship between values of the characteristic and values of soil moisture based on a value of the characteristic in the information map at the geographic location and the value of soil moisture detected by the in-situ soil moisture sensor corresponding to the geographic location;
- a predictive map generator configured to generate a functional predictive map of the worksite that maps predictive values of soil moisture to the different geographic locations in the worksite, based on the values of the characteristic in the information map and based on the predictive model;
- and
- a control system configured to control a mobile agricultural sprayer based on the functional predictive map.
A computer implemented method of generating a functional predictive map comprising:
- receiving an information map that maps values of a characteristic to different geographic locations in a worksite;
- detecting, with an in-situ sensor, a value of soil moisture corresponding to a geographic location at the worksite while a mobile agricultural sprayer is operating at the worksite;
- generating a predictive model indicative of a relationship between values of the characteristic and values of soil moisture based on the value of soil moisture detected by the in-situ sensor corresponding to the geographic location and the value of the characteristic in the information map at the geographic location;
- controlling a predictive map generator to generate the functional predictive map of the worksite that maps predictive values of soil moisture to the different geographic locations in the worksite based on the values of the characteristic in the information map and the predictive model.
An agricultural spraying system comprising:
- a communication system configured to receive an information map that includes values of a characteristic corresponding to different geographic locations in a worksite;
- an in-situ height characteristic sensor configured to detect a value of a height characteristic corresponding to a geographic location in the worksite;
- a predictive model generator configured to generate a predictive model indicative of a relationship between values of the characteristic and values of the height characteristic based on a value of the characteristic in the information map at the geographic location and the value of the height characteristic detected by the in-situ height characteristic sensor corresponding to the geographic location;
- a predictive map generator configured to generate a functional predictive map of the worksite that maps predictive values of the height characteristic to the different geographic locations in the worksite, based on the values of the characteristic in the information map and based on the predictive model;
- and
- a control system configured to control a mobile agricultural sprayer based on the functional predictive map.
