Patent ID: 8630235

Claim:
A method for the computer-aided classification of measurements for the feature-based positioning of a mobile object in a predetermined region, for which one or more exit areas are defined, by means of which the mobile object can leave and enter the predetermined region, whereby each measurement is specified by a measuring time and measured features of a plurality of base stations, whereby one feature of a base station characterizes a field emitted by the base station at the object or a field emitted by the object at the base station, the method comprising: classifying the measurements on the basis of the positions of the base stations with respect to the predetermined region and the features of the base stations measured during the respective measurements, whereby: a respective measurement of a first class is categorized as a measurement in a position of the mobile object inside the predetermined region; a respective measurement of a second class is categorized as a potential measurement in a position of the mobile object outside the predetermined region; and a respective measurement of a third class is categorized as a resolved measurement in a position of the mobile object outside the predetermined region; for a respective measurement of the second class, analyzing a number of successive measurements including the measuring time of the respective measurement up until the occurrence of a measurement of the first class as to whether the mobile object has left or entered the predetermined region by way of an exit area during the course of the number of measurements, whereby in the event that the mobile object has not left or entered the predetermined region the respective measurement is assigned to the first class.
