Title: METHOD FOR DETECTING AGRICULTURAL FIELD WORK PERFORMED BY A VEHICLE
Abstract:
The invention relates to a method for detecting agricultural field work performed by a vehicle (1), comprising: a) carrying a satellite navigation receiver (4) on the vehicle (1) and recording a sequence (FG) of position fixes (pi) and associated time stamps (ti); b) for a position fix (pi): determining a group (Gi) of position fixes that lie in a range (B); c) dividing the group (Gi) into sub-groups on the basis of a minimum time interval; d) determining trajectory sections (trj) on the basis of the sub-groups; e) determining an attribute vector (Mi) for the considered position fix (pi) comprising at least an angle (αi) between two trajectory sections (trj); and, f) if the attribute vector (Mi) satisfies a specified threshold value criterion (K), detecting the position fix (pi) as a location of field work (F).
