Localisation of a mobile terminal using visually detectable landmarks

The device (100) has a comparator (130) to assign the orientation data from the database (300) to the still image (112) of the detected landmark (202). The orientation data includes information about a spatial direction, which points to a side of the detected landmark pictured in the still image. A data processor (140) is formed to compute the position (142) of the mobile terminal based on the orientation data assigned to the still image. A camera unit (110) is provided to generate a still image of the location area. Independent claims are included for the following: (1) a method for locating a mobile terminal in a location area; and (2) a locating system for locating a mobile terminal in a location area.
