Abstract: A device, system and method for determining a position of a movable object on a two-dimensional surface obtains, via an image capture device attached to the movable object, at least one image of a portion of the two-dimensional surface. At one virtual marker is identified in at least one image, and a previously determined estimated position of the at least one virtual marker is retrieved. The previously determined estimated position determined from a combination of an image of at least one anchor point on the two-dimensional surface, the at least one anchor point defining a unique position on the two-dimensional surface, and odometry measurements based on at least two images of the two-dimensional surface. The position of the movable object on the two-dimensional surface is determined from the estimated position of the at least one virtual marker.

Abstract: The present invention relates to a method for determining a position of a terminal device (110) in a wireless communication system (100). According to the method, a first message (130-133) is broadcasted by the terminal device (110). The first message (130-133) comprises a positioning request and a terminal identifier identifying the terminal device (110). The first message (130-133) is received at a group of neighboring devices (120-123). Each neighboring device of the group of neighboring devices (120-123) is located within a wireless radio communication range of the terminal device (110). From one or more neighboring devices (120, 121) of the group of neighboring devices (120-123) a corresponding second message (140, 141) is transmitted to location server (103) of the wireless communication system (100). The second message (140, 141) comprises the terminal identifier and an indication that the terminal device (110) requested a positioning. For each neighboring device (120, 121) of the one or more neighboring devices a corresponding position information is determined. The position of the terminal device (110) is determined at the location server (103) based on the position of the one or more neighboring devices (120, 121).
