GPS-Induced Disparity Correction for Accurate Object Placement in Augmented Reality

Abstract

The use of augmented reality (AR) continues to increase, particularly in marketing and advertising, where virtual objects are showcased in the AR world, thereby expanding its various applications. In this paper, a method of linking coordinate systems to connect the metaverse with the real world is proposed and a system for correcting and displaying virtual objects in the AR environment is implemented. The proposed method calculates errors to accurately represent virtual objects in AR and presents a method to show these objects without errors. The proposed method was verified through experiments to successfully display virtual objects in AR. To minimize localization errors, semantic segmentation was used to recognize objects and estimate buildings, thereby correcting the device location. An error correction expression is also presented. The proposed system is designed to correct and display virtual objects in AR, with confirmed functionality for location correction.
