Embodiment Construction

[0017] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0018] figure 1 It is a schematic diagram showing an exemplary relationship among terminal devices, entrances and exits, and vehicles according to some embodiments of the present application.

[0019] Generally, the vehicle driver's terminal equipment has an open GPS positioning module for GPS navigation. For example, when a driver installs an online car-hailing platform application (e.g., Didi app) on his / her terminal device, the application turns on the GPS positioning module by default so that the location of the corresponding vehicle can be uploaded to the online car-hailing platform system server. Similarly, when the user starts a trip, the starting location of the trip will be uploaded to the server, and when the ...

Abstract

A System and a method for positioning a gateway of an architecture are provided. The method may include: determining a trajectory of a mobile device based on motion data acquired by the mobile deviceand a movement model (S602), acquiring a first end position of the trajectory of the mobile device (S604), detecting that the mobile device enters or exits the architecture (S606), and determining a second end position of the trajectory upon the detection as the position of the gateway (S608).

Description

technical field [0001] The present application relates to positioning technologies, and more particularly, to systems and methods for locating building entrances and exits. Background technique [0002] Accurately locating the entrances and exits of structures such as houses, buildings, parking lots or any other structure is very important. For example, to generate a layout diagram of a building, the entrance and exit are the starting points of all routes within the building. Also, if the destination is a large building located at an intersection, the entrance and exit location should be used as the end point of the navigation route. [0003] Traditionally, building entrances and exits are located manually. For example, the position of a pointing device can be determined and manually calibrated to designate the location of a building entrance. Not only is locating a large number of building entrances time-consuming, it is also expensive to hire a technician to perform the...
