Abstract
Disclosed are an image-based indoor positioning service system and method. A service server includes a communication unit configured to receive a captured image of a node set in an indoor map, and a location estimation model generation unit configured to learn the captured image of the node received through the communication unit, segment the learned captured image to obtain objects, and selectively activate the objects in the learned image to generate a location estimation model.
Claims6
A service server comprising:
- a storage that stores an indoor map where node coordinates are preset along a route through which a user walks;
- a communication module that receives, from a terminal device, a location estimation request signal including a captured image of a node at one of the node coordinates;
- a location estimation model generation unit that:
- learns the captured image, segments the captured image learned by the location estimation model generation unit into objects, and
- selectively activates the objects in the captured image learned by the location estimation model generation unit to generate a location estimation model in which a node-coordinate-specific image is mapped to each of the node coordinates, wherein the location estimation model outputs a node coordinate corresponding to an image of which a location is unknown in response to input of the image;
- and
- a location estimation unit that, in response to the communication module receiving the location estimation request signal,
- estimates a location of the terminal device by inputting the captured image to the location estimation model and obtaining a node coordinate corresponding to the captured image, and
- transmits the estimated location, to the terminal device, to cause the terminal device to display a location estimation screen that shows the captured image and the indoor map including a mark indicating the location of the terminal device identified by the node coordinate.

A terminal device comprising:
- a communication module that communicates with a service server over a communication network, the service server storing an indoor map where node coordinates are preset along a route through which a user walks;
- a storage unit that stores the indoor map;
- a capture unit that obtains a captured image of a node at one of the node coordinates;
- a display unit;
- and
- a computing device that:
- transmits a location estimation request signal including the captured image to the service server by the communication module,
- upon receiving from the service server a location of the terminal device estimated by inputting the captured image to a location estimation model and obtaining a node coordinate corresponding to the captured image, marks the location of the terminal device on the indoor map, wherein
- a node-coordinate-specific image is mapped to each of the node coordinates in the location estimation model, and
- the location estimation model outputs a node coordinate corresponding to an image of which a location is unknown in response to input of the image, and
- displays by the display unit a location estimation screen that shows the captured image and the indoor map including a mark indicating the location of the terminal device identified by the node coordinate.
