    摘要: A robotic mower boundary coverage system includes a vehicle control unit on the robotic mower commanding a traction drive system to drive the robotic mower at a specified yaw angle with respect to a boundary wire, and a boundary sensor on the robotic mower signaling the distance between the boundary wire and the vehicle control unit. The vehicle control unit alternates commands to direct the traction drive system toward and away from the boundary wire based on the distance of the robotic mower to the boundary wire.

    摘要: An automatically guided agricultural vehicle with multiple sensors is disclosed. The automatically guided agricultural vehicle includes guidance parameter identification using multi-sensor data fusion for real-time vehicle guidance. To insure robust navigation, a map-based guidance and sensor-based guidance are disclosed and integrated because no individual sensing technology is ideally suited for vehicle automation under all modes of use. The appropriate sensor and operational mode will depend on the field status of time or operation. A fiber optic gyroscope (FOG) and a real-time kinematic GPS (RTK-GPS) and machine vision are added to the guidance system in order to improve reliability of the system for vehicle guidance. The navigator includes key functions of selecting control mode, correcting position by vehicle roll/pitch inclinations, Kalman filtering, and calculating a steering angle.

    摘要: A process for determining the health of crops in a field and for correcting deficiencies in the health of the crops is disclosed. The process includes georeferencing aerial photographs of at least a portion of the field, the aerial photographs having a particular spatial resolution; determining the green plane in the aerial photographs thus taken; preparing a relative greenness map of the field based upon the nitrogen reference area, the relative greenness map providing crop status information having spatial resolution equivalent to the spatial resolution of the aerial photographs; converting the relative greenness map to a nitrogen recommendation map having spatial resolution equivalent to the spatial resolution of the photographs; and applying nitrogen to the field according to the nitrogen recommendation map, whereby the nitrogen is applied to the field without loss of spatial information. A process for treating crops is also disclosed. The process includes establishing, in a field to be treated, at least one predetermined area of high nitrogen reference; photographing from the air, georeferenced portions of the field, using a particular spatial resolution; differentiating soil and crops, in the photographs thus obtained by segmenting images to select crop pixels; preparing a relative greenness map of the field from green plane based upon the high nitrogen reference area, the relative greenness map providing crop information having spatial resolution equivalent to the particular spatial resolution; and treating the crops in the field in accordance with the relative greenness map.

    摘要: A process for determining the health of crops in a field and treating the crops in accordance with that determination. The process first establishes, in a field in which the health of the crops is to be determined, at least one predetermined reference area of crops having a determined nutrient, e.g. nitrogen, content. Then, georeferenced aerial photographs are taken of at least a portion of the field. From the photographs, the green plane is determined. From the green plane, a relative greenness map of the field based upon the nitrogen reference area is prepared. The greenness map may be transmitted to a farm vehicle on the field and thereafter, the field may be selectively treated in accordance with the nutrient deficiencies detected and recorded on the greenness map.

    摘要: A robotic mower launch point system includes a user interface for an operator to enter a plurality of launch point locations, durations and frequencies, and a vehicle control unit that stores the locations, durations and frequencies, determines a sequence of launches based on the launch point frequencies, and commands the robotic mower to exit a charging station and follow a boundary wire to each launch point in the sequence where the robotic mower mows for that launch point's duration before returning to the charging station. The vehicle control determines the sequence based on the frequency of each launch point relative to a total of the launch point frequencies.
