TERMINAL DEVICE FOR INDOOR POSITIONING BASED ON OBJECT RECOGNITION, SERVICE SERVER, AND METHOD THEREFOR

Disclosed are a terminal device for indoor positioning based on object recognition, a service server, and a method therefor. A terminal device according to one aspect of the present invention comprises: a storage unit for storing an indoor map in which preset coordinate values for each object are matched; a photographing unit; and a control unit for recognizing first and second objects from an image obtained through the photographing unit, estimating the respective virtual space positions of the first and second objects, estimating a virtual space distance between a user and each of the first and second objects by using a virtual space position of the user and the virtual space positions of the first and second objects, and estimating an indoor position of the user by using the virtual space distance.
