  • Publication number: 20080065286
    Abstract: 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.

    Abstract: 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.

  • Publication number: 20070089390
    Abstract: 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.

  • Publication number: 20070085737
    Abstract: The present invention includes a method for a combined use of a local positioning system, a local RTK system and a regional, wide-area, or global differential carrier-phase positioning system (WADGPS) in which disadvantages associated with the local positioning system, the RTK and the WADGPS navigation techniques when used separately are avoided. The method includes determining a first position of the object based on information from the WADGPS, and determining a second position of the object based on position information from a local positioning/RTK positioning system. Thereafter, position determined by the WADGPS and the position determined by the local positioning/RTK positioning system are compared.

  • Publication number: 20060271555
    Abstract: 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.

  • Publication number: 20060196158
    Abstract: 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.

  • Publication number: 20060200334
    Abstract: Presented herein is a method for predicting suitable times for performing a soil engaging operation within a field. The method includes the steps of accessing predicted values for weather and soil conditions, and then predicting values for one or more operation variables indicating operation suitability. The method then predicts suitability for performance of the soil engaging operation based on the predicted operation variables and selected suitability parameters.

  • Publication number: 20060190494
    Abstract: 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.

  • Publication number: 20050264444
    Abstract: 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.

  • Publication number: 20050228585
    Abstract: 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.

  • Publication number: 20050203702
    Abstract: The present invention includes a method for performing backup dual-frequency navigation during a brief period when one of two frequencies relied upon by dual-frequency navigation is unavailable. The method includes synthesizing the code and carrier-phase measurements on the unavailable frequency using the carrier-phase measurements on the retained frequency and a model of ionospheric refraction effects, which is updated when measurements on both frequencies are available.

  • Publication number: 20050096802
    Abstract: 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.

  • Patent number: 6789014
    Abstract: A global positioning system based navigation system for a ground vehicle, in particular an agricultural ground vehicle such as a tractor, combine, sprayer, or the like, includes an inertial compensation assembly that provides inertial augmentation to compensate global positioning system based navigation information such as position, course, and track spacing for errors caused by variation of ground vehicle attitude (i.e., roll and yaw) over non-level terrain.
