Method and system for serving three dimension web map service using augmented reality

Abstract

Disclosed is a method for a 3 -dimensional (3D) web map service using augmented reality, the method including downloading a mapping information file where 2-dimensional (2D) marker information and 3D modeling data are mapped, receiving map data including the 2D marker information from a map data providing server, rendering a map to a frame buffer in advance using the received map data, extracting an identification (ID) of the 3D modeling data through detecting 2D marker information from the map data and searching the mapping information file, extracting the 3D modeling data corresponding to the detected 2D marker information from a 3D modeling database using the ID of the 3D modeling data, additionally rendering the 3D modeling data to the frame buffer after processing the 3D modeling data, and rendering the rendered data to a screen.

Description

technical field [0001] The present invention relates to a method and system for a three-dimensional (3D) network map service using augmented reality, and in particular, to a method and system for a 3D network map service, which can be performed in advance and can be represented with a small amount of data The mapping between two-dimensional (2D) marker information and a specific 3D object, when receiving map data in real time, does not receive the entire 3D object but only receives the 2D marker information corresponding to the position of the 3D object to be drawn, and renders the 3D corresponding to the 2D marker information Modeling data from which 3D map services can be provided. Background technique [0002] Generally, an augmented reality system (augmented reality) is a virtual reality technology that displays the real world seen by the user with the eyes and the virtual world with more detailed information as a single feature, which is a hybrid virtual reality system ...

AI Technical Summary

Problems solved by technology

However, the 3D network map service system has a significantly higher load compared to the rendering time when performing network transmission data, so it is almost impossible to provide real-time services

[0007] However, although the problem of storing 3D objects in advance on the user's computer or transferring a large amount of data each time by using a cache has been solved, it is very difficult to store the object before the exact position on the map is drawn, because The orientation and declination of the map must be different based on user input in the 3D web map service
