SWBF(shrink-wrapped boundary face) 알고리즘은 조직되지 않은 3차원 측정점으로부터 표면을 재구성하기 위해 최근에 제안된 방법이다. 본 논문에서는 SWBF 알고리즘의 표면 중복문제를 제기하고, 이를 해결하기 위한 개선된 표면 재구성 방법을 제안한다. 제안된 방법은 경계셀이 아닌 모든 셀들을 내부셀과 외부셀로 구분하고, 개선된 경계면의 정의를 이용해 초기메쉬에서 표면의 중복이 발생하지 않도록 하였다. 또한, 측정 방향에 따라 표면 샘플링의 조밀도가 차이가 나는 일반적인 3차원 스캐너로부터 추출된 데이터의 처리를 위해 셀 영상에서 2차원 연결성을 정의하여 사용하였다. 실험을 통해 제안된 방법이 SWBF 알고리즘의 표면중복문제를 극복하는데 매우 유용함을 알 수 있었다.
