Method to express location information using augmented reality

The present invention relates to a method to express location information using augmented reality, proving content relates to a location through a smart phone without a user having to visit the inside of a building by providing various 3D UIs of the location through a location information expressing application using augmented reality. The method to express location information using augmented reality includes: a step in which the virtual information for a target location is stored based on the vision, and a based station for the target location is maintained; a step of enlarging an image about the target location around the center of the target location and reading it in the form of a border; a step of searching a database where the target location is stored based on the read image and reading virtual information about the target location corresponding to the read image; and a step of adding the read virtual information on the top side of the target location as an annotation. [Reference numerals] (AA) START; (BB) END; (S100) Maintain virtual information database of a recognition target location; (S200) Read an recognition target location image; (S300) Read virtual information corresponding to the image; (S400) Add an addnotation
