본 발명은 본 발명은 사용자 단말의 GPS 좌표에 대응하는 타일 데이터에 포함된 기준 특징점의 좌표와, 사용자 단말의 카메라에 의해 촬영된 영상 내 기준 특징점의 위치 변화에 기초하여 단말 좌표를 결정함으로써, 사용자의 현재 위치를 정확히 추정하는 방법에 관한 것이다.
Disclosed herein is a method for exactly estimating the current location of a user and calling a vehicle to the estimated location on the basis of a GPS coordinate of a user terminal and a coordinate of a feature point recorded by the user terminal. The method for calling a vehicle according to an embodiment includes transmitting a GPS coordinate of a terminal to a server when a service request signal is input by a user, receiving tile data corresponding to the GPS coordinate of a terminal from the server, recording an external image using a camera, and extracting a feature point from the recorded external image, identifying any one reference feature point matched with the feature point extracted from the external image among a plurality of reference feature points included in the tile data, determining a terminal coordinate on the basis of a coordinate of the identified reference feature point and on the basis of a change in a location of the reference feature point in the external image, and transmitting the determined terminal coordinate to the server, and receiving a vehicle coordinate of a vehicle for transportation allocated to the terminal coordinate from the server.
