Abstract
Disclosed herein are various devices, systems, and methods for use in agricultural, particularly for use in harvesting agricultural crop such as corn. Various implementations relate to methods and devices for measuring plant stalk cross-sectional area during harvest and providing additional methods of predicting and displaying yield on a row-by-row level in real time.
Claims16
A method for counting and measuring stalks comprising:
- generating displacement signals from one or more sensing members when a stalk passes through a sensor;
- gathering stalk velocity data comprising the velocity of the stalk as it passes through the sensor;
- correlating the displacement signals with the stalk velocity data;
- generating stalk perimeter data from the displacement signals and the stalk velocity data;
- and
- determining stalk cross sectional area from the stalk perimeter data,
- wherein stalk cross-sectional area is determined in real-time or near real-time.
4 more elements
A system for measuring a cross-sectional area of a stalk at a row unit, comprising:
- (a) at least one sensor assembly disposed on the row unit, the at least one sensor assembly configured to generate width measurements as the stalk traverses the at least one sensor assembly;
- (b) at least one stalk velocity sensor configured to measure a velocity of the stalks as the stalk traverses the at least one sensor assembly;
- and
- (c) a processor in communication with the at least one sensor assembly and the at least one stalk velocity sensor,
- wherein the width measurements and velocity of the stalks are processed by the processor to generate stalk perimeter data from which stalk cross-sectional area is determined,
- wherein stalk cross-sectional area is determined in real-time or near real-time.
3 more elements
A system for measuring stalks on a row unit comprising:
- (a) a sensor assembly disposed on the row unit, the sensor assembly comprising at least one stalk measuring sensor and at least one stalk velocity sensor;
- and
- (b) a processor in operative communication with the sensor assembly, the processor configured to process data generated by the sensor assembly to estimate a stalk perimeter,
- wherein the stalk measuring sensor is configured to generate a plurality of width measurements in a time series and wherein the plurality of width measurements are correlated to an estimated stalk perimeter,
- wherein the at least one stalk velocity sensor is configured to generate a velocity value for each stalk as the stalk traverses the sensor assembly, and
- wherein stalk perimeter is determined in real-time or near real-time.
