Abstract: One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

Abstract: A radio frequency (RF) grain mass and constituent measurement system utilized onboard a combine harvester includes an RF sensor subsystem for capturing RF sensor readings of a harvested grain within an area of the combine harvester. A memory stores an RF characteristic database, which contains RF characteristic testing data collected for tested grain samples over one or more tested frequency ranges. A controller, operably coupled to the RF sensor subsystem and to the memory, is configured to: (i) receive the RF sensor readings from the RF sensor subsystem; (ii) determine grain mass and a first constituent content of the currently-harvested grain based, at least in part, on an analytical comparison between the RF sensor readings and the RF characteristic testing data; and (iii) perform at least one action in response to determining the grain mass and the first constituent content of the harvested grain.

The simultaneously harvested crops may be separated into individual crop flows that are handled separately from each other.

Abstract: Control zones are identified on a thematic map and work machine actuator settings are identified for each control zone. A position of the work machine is sensed and actuators on the work machine are controlled based on the control zone that the work machine is in, and based upon the actuator settings corresponding to the control zone. The control zone is then divided, on a display, into a harvested portion of the control zone on which an observed condition value is shown, and control zone that has yet to be harvested, on which an estimated value of the condition is shown.

Abstract: A priori geo-referenced data is obtained for a worksite, along with field data that is collected by a sensor on a work machine that is performing an operation at the worksite. A predictive model is generated, while the machine is performing the operation, based on the geo-referenced data and the field data. A model quality metric is generated for the predictive model and is used to determine whether the predictive model is a qualified predicative model. If so, a control system controls a subsystem of the work machine, using the qualified predictive model, and a position of the work machine, to perform the operation.

Abstract: A map is obtained by an agricultural system. The map includes values of one or more characteristics at different geographic locations in a worksite. In-situ sensor data indicative of values of one or more crop constituents at cut heights is obtained as the mobile machine operates at the worksite. A predictive model generator generates a predictive model that models a relationship between values of the one or more crop constituents at cut heights and the values of the one or more characteristics in the map. A predictive map generator generates a predictive map that predicts values of the one or more crop constituents at two or more cut heights at different geographic locations in the worksite based on the predictive model. The predictive map can be output and used in automated machine control.

Abstract: In some implementations, a computing device can simulate a virtual parallax to create three dimensional effects. For example, the computing device can obtain an image captured at a particular location. The captured two-dimensional image can be applied as texture to a three-dimensional model of the capture location. To give the two-dimensional image a three-dimensional look and feel, the computing device can simulate moving the camera used to capture the two-dimensional image to different locations around the image capture location to generate different perspectives of the textured three-dimensional model as if captured by multiple different cameras. Thus, a virtual parallax can be introduced into the generated imagery for the capture location. When presented to the user on a display of the computing device, the generated imagery may have a three-dimensional look and feel even though generated from a single two-dimensional image.

Abstract: Control zones are identified on a thematic map and work machine actuator settings are identified for each control zone. A position of the work machine is sensed and actuators on the work machine are controlled based on the control zone that the work machine is in, and based upon the actuator settings corresponding to the control zone. The control zone is then divided, on a near real-time display, into a harvested portion of the control zone on which an observed condition value is shown, and control zone that has yet to be harvested, on which an estimated value of the condition is shown.

Abstract: A system and a method are disclosed for determining a range of potential distances between a work machine and an object. The system receives an image captured by a camera on the work machine and identifies an object in the image. The system determines an angle between the camera and the object, a height associated with the object, and an uncertainty associated with the height. Based on the angle, the height, and the uncertainty, the system determines a range of potential distances between the work machine and the object. The shortest distance in the range is compared to a threshold distance for safe operation of the work machine. When the shortest distance in the range is less than the threshold distance, the system causes the work machine to perform a safety action.
