description An AEC industrial augmented reality service method using grid partitioning and caching, according to the present invention, comprises: a grid size determination step of determining the size of a grid that can be serviced in a terminal; a data partitioning step of partitioning data to be augmented into a cube block unit of the size of the grid; a data loading step of loading, into the terminal, the data to be augmented into the cube block unit corresponding to the location of an AR camera; a camera position calculation step of calculating a center point of a currently located grid and the location of the AR camera in real time when the AR camera is moved; and a new grid augmentation step of loading an augmenting data to be augmented of a new grid when it is determined that the new grid is needed for the AR camera's field of view. Therefore, there is an effect of tracking and calculating the location of an AR camera in real time without using separate external equipment, such as GPS signals or beacons. 본 발명에 따른 그리드 분할 및 캐싱을 이용한 AEC 산업용 증강현실 서비스 방법은, 단말기에 서비스 가능한 그리드(Grid) 사이즈를 결정하는 그리드 사이즈 결정단계, 상기 그리드 사이즈의 큐브 블록 단위로 증강 대상 데이터를 분할하는 데이터 분할단계, AR카메라의 위치에 대응하는 큐브 블록 단위의 증강 대상 데이터를 상기 단말기에 로딩하는 데이터 로딩단계, 상기 AR카메라의 이동 시, 현재 위치한 그리드의 중심점과 상기 AR카메라의 위치를 실시간 계산하는 카메라 위치 계산단계, 및 상기 AR카메라의 시야에 새로운 그리드가 필요하다고 판단되는 경우, 상기 새로운 그리드의 증강 대상 데이터를 로딩해 증강하는 신규 그리드 증강단계를 포함한다.
