Abstract
A vegetation index characteristic is assigned to an image of vegetation at a worksite. The vegetation index characteristic is indicative of how a vegetation index value varies across the corresponding image. The image is selected for predictive map generation based upon the vegetation index characteristic. The predictive map is provided to a harvester control system which generates control signals that are applied to controllable subsystems of the harvester, based upon the predictive map and the location of the harvester.
Claims20
A method of controlling a work machine, comprising:
- receiving a plurality of images of spectral response at a worksite;
- identifying a set of vegetation index values based on the spectral response;
- identifying a vegetation index characteristic, corresponding to each image, indicative of how the set of vegetation index metric values varies across the corresponding image;
- selecting an image, from the plurality of images, based on the vegetation index characteristic;
- generating, from the selected image, a predictive map;
- and
- controlling a controllable subsystem of the work machine based on a location of the work machine and the predictive map.
A work machine, comprising:
- a communication system configured to receive a plurality of images of vegetation at a worksite;
- a controllable subsystem;
- an image selector configured to generate a vegetation index characteristic that includes a variability, distribution, and magnitude metric, corresponding to each image, indicative of how a vegetation index value varies across each image, and to select an image based on the vegetation index characteristic;
- a processor configured to generate a predictive map based on the selected image;
- and
- subsystem control logic configured to control the controllable subsystem of the work machine based on a location of the work machine and the predictive map.
An image selection system, comprising:
- a communication system configured to receive a plurality of images of vegetation at a worksite;
- an image selector configured to generate a vegetative index variability metric, corresponding to each image, indicative of how a vegetation index value varies across each image, and to select an image based on the vegetation index variability metric;
- and
- a processor configured to generate at least one predictive map based on the selected images.
