TERMINAL AND COMPUTER-READABLE RECORDING MEDIUM WITH PROGRAM FOR PROVIDING INDOOR LOCATION BASED SERVICES BY USING AUGMENTED REALITY

摘要

PURPOSE: A terminal for providing an indoor location based service by using AR(Augmented Reality) and a computer readable recording medium are provided to display AR information which provides altitude information to each object existed in an indoor environment. CONSTITUTION: A coordinate setting unit(210) sets a random reference point by using a constructed three-dimensional coordinate system. A calculation unit(220) generates vector information by calculating set reference point, a calculated user location value, and a set object location value. A rotation angle measuring unit(230) recognizes a rotation angle according to a current progress direction. A projection unit(240) displays AR information based on the rotation angle and the vector information as overlay and a specific object within an obtained image through a camera module.
