摘要： A method for mapping a height of a crop in a field divided into a plurality of areas includes determining a height of a cutting bar of an agricultural machine and receiving data from a crop height sensor. The height of crops sensed by the crop height sensor is determined based on the height of the cutting bar and data from the crop height sensor. The crop height is then associated with one of a plurality of areas of the field based on a location of the crop height sensor. In one embodiment, the height of a reel of the agricultural machine is also used in determining the height of crops. The crop height data is used to generate a field map that is used to generate a field treatment plan.

摘要： The present disclosure describes a method and an apparatus for determining a corrected position of a vehicle based on a stable landmark. The method includes determining a last known position vector of the vehicle; capturing an image within a vicinity of a vehicle using an imaging device; identifying a stable landmark within the captured image based on a previously constructed reference map of the vicinity of the vehicle; determining a correction for a position of the vehicle based on the determined last known position vector of the vehicle and the identified stable landmark; and determining an updated position of the vehicle based on the determined correction.

摘要： The present invention discloses methods of accuracy improving for code measurements in GLONASS GNSS receivers. One component of error budget in code measurements of GLONASS receivers is caused by a difference in signal delays arising in the receiver analog Front End and antenna filter on different channel frequencies specific to GLONASS satellites. Methods to compensate for differences in delays for different GLONASS channel frequencies have been proposed using data collected from a GLONASS signals simulator.

摘要： A system and method are provided for determining the position and orientation of an implement on a work machine in a non-contact manner using machine vision. A 3D camera, which is mounted on the vehicle with a field of view that includes components on the implement (e.g., markers in some examples), determines a three-dimensional position in a local coordinate system of each of the components. A global positioning system in cooperation with an inertial measurement unit determines a three-dimensional position and orientation of the 3D camera in a global coordinate system. A computing system calculates a three-dimensional position in the global coordinate system for the components using the local three-dimensional positions of the components and the global three-dimensional position and orientation of the 3D camera. The position and orientation of the implement can then be calculated based on the calculated global three-dimensional positions of the components.

摘要： A laser measuring system comprising a laser transmitter and a laser receiver is provided. The laser transmitter includes one or more laser sources for projecting an initial laser pulse and a reflective surface. The laser receiver includes a first reflective surface for reflecting the initial laser pulse to provide a first reflected laser pulse, and a second reflective surface for reflecting the initial laser pulse to provide a second reflected laser pulse. The laser receiver further includes a photo detection unit for receiving 1) a first double reflected laser pulse produced by the first reflected laser pulse reflecting off the reflective surface of the laser transmitter, and 2) a second double reflected laser pulse produced by the second reflected laser pulse reflecting off the reflective surface of the laser transmitter. The laser receiver determines an orientation angle associated with the laser receiver based on the first and second double reflected laser pulse.

摘要： Systems and methods are provided for determining a soil roughness measure. A transducer transmits an ultrasonic signal towards a soil surface and receives a first echo signal of the ultrasonic signal and a second echo signal of the ultrasonic signal. A first distance between the transducer and a first point on the soil surface is calculated based on the first echo signal of the ultrasonic signal. A second distance between the transducer and a second point on the soil surface is calculated based on the second echo signal of the ultrasonic signal. A soil roughness measure of the soil surface is determined based on a difference between the first distance and the second distance.

摘要： In one embodiment, a method for processing harvest yield data includes the steps of receiving load data from a grain cart and receiving harvest yield data from a combine harvester. The load data and harvest yield data are post-processed to generate enhanced harvest yield data. The combine harvester and the grain cart can operate in an on-the-go unloading harvest operation or a stationary unloading harvest operation. Post-processing can include creating a field boundary for a harvest area, determining a start time and start position for the combine harvester within the field boundary, and determining an end time and end position for the combine harvester within the field boundary. The total grain yield weight estimated by a yield monitor can be calibrated to match the grain cart total scale weight.

摘要： A GNSS compact antenna comprising a conducting ground plane and a driven element for exciting right hand circularly polarized waves having a multi-segment structure such that the area around the driven element is divided into elementary cells with conductors and circuit elements arranged therein. The antenna includes a set of circuit elements connecting the neighboring elementary cells and the driven element. Each elementary cell has a horizontal conductor over the ground plane, and each elementary cell can have a vertical conductor and a circuit element connecting the horizontal and vertical conductors. The horizontal conductor comprises a set of characteristic points to which circuit elements, connecting neighboring elementary cells or any elementary cell and the driven element, are connected. Both the impedance of each circuit elements and the design of each elementary cell can be different, but the antenna has four-fold rotational symmetry relative to the vertical axis.
