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.

Abstract: A mobile agricultural machine obtains an agricultural characteristic map indicative of agricultural characteristics of a field, wherein the agricultural characteristic map is based on data collected at or prior to a first time. The mobile agricultural machine obtains supplemental data indicative of characteristics relative to the worksite, the supplemental data collected after the first time. An agricultural characteristic confidence output, indicative of a confidence level in the agricultural characteristics indicated by the agricultural characteristic map, is generated based on the agricultural characteristic map and the supplemental data. In some examples, an action signal is generated to control an action of the mobile agricultural machine based on the agricultural characteristic confidence output.

Abstract: Methods and system for minimizing soil compaction relating to operations performed by agricultural machines. The agricultural machines can be guided so that at least one engagement body travels along an existing track path that was established by a prior travel of the same or different agricultural machine. Further, travel plans can determine the sequence in which the agricultural machine(s) travel in areas in the field so that travel on the track path(s) can be initiated in drier regions in the field. Operation of agricultural machines can also be adjusted to minimize deviations of other agricultural machines from existing track paths. For example, a windrower can operate a diverter to deposit a windrow at an offset location, and with a non-linear pattern, that may limit a baler from deviating from an existing track path while collecting crop material from the windrow, while also assisting in forming uniformly shaped crop bales.

Additionally, a method includes receiving a command associated with a spatio-temporal query, wherein the expression comprises spatial regular expressions (SpREs). Thereafter, performing the spatio-temporal query of a plurality of perception data streams using the SpREs, where the SpREs describe spatio-temporal patterns to be searched within the plurality of perception data streams.

Abstract: A seeding machine moves over the ground and includes a frame, at least one hopper containing seeds to be planted and planting row units connected to the frame. Each of the row units includes a seed metering device that separates and guides individual seeds into a planting position, and a shaft that reciprocates with respect to the frame through a stroke path. The stroke path includes extension towards the ground to a lowered position and retraction away from the ground to a raised position. The shaft engages one of the seeds from the planting position while the shaft is near the raised position. The shaft moves the one of the seeds downward while the shaft extends toward the ground to create an opening in the ground by pressing the one of the seeds into ground while the shaft is near the lowered position.

Abstract: An implement management system detects implement wear and monitors implement states to modify operating modes of a vehicle. The system can determine implement wear using the pull of the implement on the vehicle, the force and angle of which is represented by an orientation vector. The system may measure a current orientation vector and determine an expected orientation vector using sensors and a model (e.g., a machine learned model). Additionally, the implement management system can determine an implement state based on images of the soil and the implement captured by a camera onboard the vehicle during operation. The system may apply different models to the images to determine a likely state of the implement. The difference between the expected and current orientation vectors or the determined implement state may be used to determine whether and how the vehicle's operating mode should be modified.

Abstract: The present disclosure describes aspects of systems and methods for machine-learned spectrum analysis. A policy may be learned through an unsupervised reinforcement machine learning procedure. The procedure may comprise training an actor to determine actions in an environment. The actor may be trained based, at least in part, on rewards determined for the actions by an adversarial network, such as a critic. The critic may learn a value function through supervised learning. By contrast, the actor may learn the policy the unsupervised reinforcement learning. The system may generate training data comprising noise configured to model noise likely to exist during real world operation in different use cases. Policies may be trained for different use cases using training data configured to include noise characteristic of the different use cases.

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.

The predictive map can be output and used in automated machine control.
