摘要:
A preliminary guidance data is determined for the vehicle during an evaluation time window. A vision module collects vision data from a vision module during the evaluation time window. Vision guidance data is determined from the collected vision data. A vision quality estimator estimates vision quality data for at least one of the vision data and the vision guidance data during the evaluation time window. The vision quality data is based on a cross correlations and an r-squared value. An adjuster adjusts the preliminary guidance data to a revised guidance data based on the vision guidance data such that the revised guidance data is registered with or generally coextensive with the vision guidance data, if the vision quality data exceeds a minimum threshold.

Preliminary guidance data is determined for the vehicle during an evaluation time window. A vision module collects vision data from a vision module during the evaluation time window. Vision guidance data is determined from the collected vision data. A vision quality estimator estimates vision quality data for at least one of the vision data and the vision guidance data during the evaluation time window. The vision quality data is based on a regression path and density grid points. An adjuster adjusts the preliminary guidance data to a revised guidance data based on the vision guidance data such that the revised guidance data is registered with or generally coextensive with the vision guidance data, if the vision quality data exceeds a minimum threshold.

A system and method of guiding a vehicle comprises establishing elevation data and corresponding location data for a work area. A particular location of a vehicle within the work area is determined. Roll data and pitch data are estimated corresponding to the particular location. The vehicle is guided based upon the estimated roll data and the pitch data such that the vehicle follows a desired path.

The present invention is directed to a method for acquiring elevation data for an area. The method includes using a GPS receiver to map ground elevations while driving back and forth over an area and periodically recording position, elevation, and time. Then, at least one track is made across the parallel tracks so that the cross track intersects the parallel tracks. The data obtained is processed and elevation data from the cross track is used to adjust elevation data for the parallel tracks, compensating for elevation drift in measurements recorded by the GPS receiver. The adjusted data for the entire area is processed using the method of the present invention to obtain an elevation map for the area.
摘要:
A method for dividing a field into zones with similar crop attributes and developing a mission plan for steering the harvester to selectively harvest crops based on one or more of the attributes. The attributes include protein level, starch level, oil level, sugar content, moisture level, digestible nutrient level, or any other crop characteristic of interest. The method can be applied to selectively harvest and/or segregate according to attribute any crop, including grains such as wheat, corn, or beans, fruits such as grapes, and forage crops. Directed crop sampling provides absolute value and variance information for segregated batches of harvested crop.

Presented herein is a method for predicting suitable times for performing a crop harvesting operation within a field. The method includes the steps of accessing predicted values for weather, crop, and soil conditions, and then predicting values for one or more additional operation variables indicating operation suitability. The method then predicts suitability for performance of the crop harvesting operation based on the predicted operation variables and selected suitability parameters.

A method and system for tracing the identity of an agricultural product comprises holding an agricultural product in a container. The container is associated with a tag. Harvesting data is obtained. The harvesting data is associated with the harvesting of an agricultural product. The harvesting data is stored as stored information by transmitting the harvesting data for storage as stored information associated with a data management system. Primary transportation data is obtained. The primary transportation data is associated with the transportation of the product to primary storage. The primary transportation data is added to the stored information.

The present invention includes a method for a combined use of a local RTK system and a regional, wide-area, or global differential carrier-phase positioning system (WADGPS) in which disadvantages associated with the RTK and the WADGPS navigation techniques when used separately are avoided. The method includes using a known position of a user receiver that has been stationary or using an RTK system to initialize the floating ambiguity values in the WADGPS system when the user receiver is moving. Thereafter, the refraction-corrected carrier-phase measurements obtained at the user GPS receiver are adjusted by including the corresponding initial floating ambiguity values and the floating ambiguity values are treated as well known (small variance) in subsequent processes to position the user receiver in the WADGPS system.

摘要:
Initial data is acquired on an agricultural product associated with a harvesting time. The acquired initial data is transmitted (e.g., handed off) via an electromagnetic signal or wireless communication to an intermediate data processing system associated with a handler of the agricultural product. Additional data is appended to the acquired initial data received at the intermediate data processing system to form composite data. The composite data is transmitted via an electromagnetic signal or wireless communication to at least one of a receiver and a data processing system for processing or storing the composite data. The composite data is transferred to or made available to a data management system, which may be accessible to one or more users who seek access to at least one of the initial data, the additional data, and the composite data on the agricultural product or a derivative thereof.
