Abstract:
An object detection system utilizing one or more thin, planar structured light patterns projected into a volume of interest, along with digital processing hardware and one or more electronic imagers looking into the volume of interest. Triangulation is used to determine the intersection of the structured light pattern with objects in the volume of interest. Applications include navigation and obstacle avoidance systems for autonomous vehicles (including agricultural vehicles and domestic robots), security systems, and pet training systems.
Abstract:
The present invention relates to a method for making a work machine automatically perform work tasks, which work machine comprises a positioning equipment connected to a control and monitoring computer and capable of detecting the current position of the vehicle, control and sensor means connected to the steering and drive members of the vehicle as well as connected to the control and monitoring computer and capable of controlling and detecting the steering and drive members of the vehicle. The invention is characterised by the steps of performing the current work task by an operator of the vehicle during simultaneous recording and storage in the control and monitoring computer of information from the positioning equipment as well as the sensor means, performing the current work task based on the stored information in the order it was stored during activation of the steering means. The invention also comprises a device and a computer program for performing the method.
Abstract:
The invention concerns a method and device for automatically applying fertilizers, in particular fresh sewage sludge material or similar organic fertilizers, onto the ground, in particular onto areas used for agricultural purposes. The device comprises a vehicle for applying the fertilizer, means (13) for holding the fertilizers, means (6, 7) for discharging the fertilizers out of the means (13) and applying them to the ground, and means (5) for controlling the amount of fertilizer to be applied as a function of time or the speed of the vehicle. Means (2, 3) are used to determine the location and speed on the ground using satellite navigation (GPS) and a radar sensor (8) for determining the speed of the vehicle (1). The device further comprises means (9) for determining the vehicle's direction of travel in situations in which the satellite navigation system cannot provide corresponding values for reasons inherent in the system.
Abstract:
A method of guiding a vehicle in which an image of a scene containing rows of objects is acquired and stored. A portion of the image within an applied parallelogram is analysed to identify objects having a brightness that exceeds an adaptive threshold. A regression calculation is performed on the objects to locate a position of the row in terms of a lateral displacement value compared to a previously identified row. The lateral displacement value is converted to a steering correction signal which is applied to a steering means of the vehicle to effect vehicle guidance. A number of portions can be analysed simultaneously to identify a number of rows thereby improving the robustness of the method. A vehicle guidance system embodying the method is also disclosed.
Abstract:
Die vorliegende Anmeldung betrifft ein Verfahren zum Planen eines Bearbeitens eines zumindest viereckigen Bereichs (10) eines landwirtschaftlichen Felds mittels eines lenkbaren oder steuerbaren landwirtschaftlichen Arbeitsgeräts, wobei der Bereich (10) zwischen seinen Ecken (11, 13, 15, 17) Randabschnitte (12, 14, 16, 18) und dabei einen ersten Randabschnitt (12) und einen zweiten Randabschnitt (14) gegenüber dem ersten Randabschnitt (12) aufweist und wobei der zweite Randabschnitt (14) schräg zum ersten Randabschnitt (12) verläuft. Dabei werden mehrere nebeneinander verlaufende erste Arbeitsbahnen (20) und mehrere nebeneinander verlaufende zweite Arbeitsbahnen (22) bestimmt, eine Fahrspur (24), die zumindest teilweise entlang den ersten Arbeitsbahnen (20) und den zweiten Arbeitsbahnen (22) verläuft und entlang der das landwirtschaftliche Arbeitsgerät über den Bereich (10) bewegt werden soll, bestimmt, mehrere Einlenkpunkte (26) entlang der Fahrspur (24), an denen das Arbeitsgerät von einer Richtung entlang einer der ersten Arbeitsbahnen (20) in eine Richtung entlang einer der zweiten Arbeitsbahnen (22) gelenkt wird, bestimmt, so dass die Fahrspur (24) mit zunehmender Entfernung (30) vom ersten Randabschnitt (12) weniger entlang den ersten Arbeitsbahnen (20) und mehr entlang den zweiten Arbeitsbahnen (22) verläuft.
Abstract:
Die vorliegende Erfindung betrifft die Planung und Ausführung von landwirtschaftlichen Maßnahmen anhand von Fernerkundungsdaten und lokalen Felddaten. Mit Hilfe von Fernerkundungssensoren können die Bedarfsgesamtmenge und teilflächenspezifische Bedarfsmengen an Pflanzenschutzmitteln und/oder Nährstoffen und/oder Saatgut und/oder dergleichen ermittelt und auf Basis dieser Informationen der Einsatz einer Applikationsvorrichtung geplant werden. Mit Hilfe von lokalen Feldsensoren werden die aktuellen lokalen Bedarfsmengen im Feld ermittelt, so dass die Applikationsvorrichtung die entsprechenden Mengen bedarfsgerecht applizieren kann.
Abstract:
The present invention relates to a support system for determining a trajectory to be followed by an agricultural work vehicle, when working a field, said system comprises: a mapping unit configured for receiving: i) coordinates relating to the boundaries of a field to be worked; and ii) coordinates relating to the boundaries of one or more obstacles to be avoided by said work vehicle; wherein said one or more obstacles being located within said field; a capacity parameter unit configured for receiving one or more capacity parameters relating to said working vehicle; a trajectory calculating unit configured for calculating an optimized trajectory to be followed by said work vehicle; wherein said optimized trajectory is being calculated on the basis of said coordinates received by said mapping unit; and one or more of said one or more capacity parameters received by said capacity parameter unit.
Abstract:
A work vehicle includes at least one sensor configured to detect at least one property of a work area. The work vehicle includes a controller comprising a processor operatively coupled to a memory, wherein the controller is configured to receive a first signal from an at least one sensor indicative of the at least one property of the work area, to determine whether an obstacle occupies one or more locations of the work area by creating or updating a map having one or more cells that correspond to the one or more locations of the work area, wherein each of the one or more cells indicate whether the obstacle occupies the respective locations of the work area based on the at least one property, and to send a second signal based on the map.
