Method, Device and System for Displaying Augmented Reality POI Information

A method for displaying Point of Interest (POI) information for a vehicle, includes: obtaining a digital map; obtaining localization information of the vehicle; obtaining coordinate information of the POI and type information of the POI from the digital map; receiving reality image data from a camera mounted on the vehicle; transforming the coordinate information of the POI from a coordinate system of the digital map to a coordinate system of the camera; generating a guide sign indicating the POI in the coordinate system of the camera based on the coordinates information of the POI transformed to the coordinate system of the camera and the type information of the POI; and superimposing the guide sign indicating the POI on the image data received from the camera.
