Abstract

본 발명에 따른 그룹 데이터에 의한 정렬 방법은 최초 그룹 데이터를 생성하여 3차원 이미지 데이터 생성 및 얼라인 과정을 수행하다가, 일정 시간 이상 3차원 볼륨 데이터가 서로 연결되지 않는 상태가 지속되면 신규 그룹 데이터를 생성함으로써 적어도 하나 이상의 단속적인 그룹 데이터를 생성할 수 있다. 신규 그룹 데이터에 저장되는 3차원 볼륨 데이터가 이전에 생성된 그룹 데이터의 3차원 볼륨 데이터와 중첩되는 부분이 확인되면, 중첩되는 부분을 서로 연결하도록 추가 얼라인 단계가 수행됨으로써 결과적으로 데이터 공백을 보완하고 환자의 전체 구강 모델 데이터를 용이하게 획득할 수 있는 이점이 있다.
