System for measuring plant attributes using a priori plant maps
First Claim
Patent Images
1. A system for measuring plant attributes during harvesting of a row crop comprising:
- a harvester having a row unit with stripper plates forming a gap therebetween to receive an individual plant in a row;
a plant attribute sensor coupled to the row unit;
a digital a priori plant location map identifying an anticipated presence of the individual plant in the row of plants; and
an electronic control unit (ECU) coupled to the plant attribute sensor and configured to retrieve and use the a priori plant location map to anticipate presence of the individual plant to be harvested and to use the anticipated presence of the individual plant as part of determining a yield of the individual plant based upon signals the plant attribute sensor.

Abstract
A system for measuring plant attributes comprises a plant attribute sensor (103, 108, 110); a digital a priori plant location map (118); and an ECU (126) coupled to the plant attribute sensor (103, 108, 110) and configured to retrieve and use the a priori plant map and to anticipate a plant measurement based upon the a priori plant map and to use that anticipation to improve the accuracy of the plant measurement.

10. A system for measuring plant attributes during harvesting of a row crop comprising:
-
a harvester having a row unit with stripper plates forming a therebetween to receive an individual plant in a row; a plant attribute sensor coupled to the row unit; and an electronic control unit (ECU) coupled to the plant attribute sensor and configured to;
retrieve an a priori plant location map identifying an anticipated presence of the individual plant in the row of plants;
receive signals from the plant attribute sensor; and
determine plant measurements from (1) signals received from the plant attribute sensor and (2) the anticipated presence of the individual plant as identified by the retrieved a priori plant location map, wherein the ECU is configured to create a sensor sampling window based upon the anticipated presence of a plant based upon the retrieved a priori plant location map, wherein the ECU is further configured to receive data from the plant attribute sensor during the sensor sampling window and wherein the ECU is further configured to reject data from the plant attribute sensor outside of the sensor sampling window. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A system for measuring plant attributes during harvesting of a row crop comprising:
-
a harvester having a row unit with stripper plates forming a gap therebetween to receive an individual plant in a row; a plant attribute sensor coupled to the row unit; and an electronic control unit (ECU) coupled to the plant attribute sensor and configured to;
retrieve an a priori plant location map identifying an anticipated presence of the individual plant in the row of plants;
receive signals from the plant attribute sensor; and
determine plant measurements from (1) signals received from the plant attribute sensor and (2) the anticipated presence of the individual plant as identified by the retrieved a priori plant location map, wherein the anticipated plant presence is used to adjust a value of as-received data from the plant attribute sensor.
