YIELD ESTIMATION
First Claim
1. A method comprising:
- receiving a first signal indicating an aggregate yield measured by an aggregate yield sensor during a measurement interval;
receiving a second signal indicating a plurality of geo-referenced regions across which a harvester has traveled prior to the measurement interval;
allocating, to each of at least two geo-referenced regions, an aggregate yield portion allocation based upon different conveyance imes for crops to the aggregate yield sensor and Visual-Infrared Vegetative Index data derived from sensing of plants in selected portions of the electromagnetic spectrum at a time other than harvest; and
outputting the aggregate yield portion allocations.

Abstract
A method and apparatus estimate yield. A first signal is received that an aggregate yield measured by an aggregate yield sensor during a measurement interval. A second signal is received that indicates a plurality of geo-referenced regions across which a harvester has traveled prior to the measurement interval. The method and apparatus allocate, to each of at least two geo-referenced regions, an aggregate yield portion allocation based upon different travel times for crops to the aggregate yield sensor Visual-Infrared Vegetative Index data derived from sensing of plants in selected portions of the electromagnetic spectrum at a time other than harvest. The aggregate yield portion allocations are output.

12. An apparatus comprising:
-
a harvester; a sensor to output signals indicating an aggregate yield harvested by the harvester header during a measurement interval; a location identifier to identify a plurality of geo-referenced regions across which the harvester has traveled prior to the measurement interval; and a processor to; determine the aggregate yield from the signals outputted by the sensor during the measurement interval and to allocate the aggregate yield to the plurality of geo-referenced regions based upon different travel times for crops sensed by the aggregate sensor during the measurement interval to travel to the aggregate sensor and Visual-Infrared Vegetative Index data derived from sensing of plants in selected portions of the electromagnetic spectrum at a time other than harvest; and output crop allocations to each of the plurality of geo-referenced regions. - View Dependent Claims (13, 14, 15, 16)

17. A non-transitory computer-readable medium containing instructions to direct a processor to:
-
obtain Visual-Infrared Vegetative Index (VIRVI) data derived from sensing of plants in selected portions of the electromagnetic spectrum at a time other than harvest; receive a second signal indicating a plurality of geo-referenced regions across which a harvester has traveled prior to the measurement interval; allocate, to each of the plurality of geo-referenced regions, an aggregate yield portion allocation based upon different travel times for crops to the aggregate yield sensor and the VIRVI data; and output a map of the plurality of geo-referenced regions, the map being at least partially based upon the aggregate yield portion allocations. - View Dependent Claims (18, 19, 20)
