Abstract

In this paper, we propose setting measurement point in the 3D scan data based on the manual measurement data. The optimal 3D body scan postures and measurement points for automatic measurement of breast were set up. The outer breast point may be different depending on the body shape or standing posture as it is on the line connected from the bisecting point of the lateral waist thickness to front armpit point. Therefore, it is necessary to consider the breast-related outer point proposed in this study. And many researches need to reduce the differences between MAM and 3D dimension items associated with the upper breast point. When measuring depth, the difference by pressing in MAM should be taken into account. And the differences in flexion depending on breast type can make a difference in the 3D measurement. So the measurement method in 3D scan should be further studied depending on the types of breast and verified by multiple subjects.

직접 측정방법을 기반으로 3차원 스캔 데이터에서 유방의 자동측정을 위한 유방과 관련된 측정점 설정과 이상적인 3차원 스캔 자세를 제안하였다. 특히 직접 측정법에서의 유방 바깥쪽점은 체형과 자세에 따라 변동되기 쉬우므로 3차원 측정법에서는 유방에서 찾는 새로운 방법을 제안하였다. 유방의 윤곽선이 뚜렷하지 않은 유방 위쪽의 유방 위쪽점은 겨드랑접힘점을 기준으로 설정되는데 직접측정법에서의 유방 위쪽점이 3차원 스캔데이터에서 측정된 유방위쪽점보다 높게 설정됨을 알 수 있었다. 그러므로 직접 측정치와 3차원 측정치 간의 오차를 줄이기 위해서는 유방 위쪽점 설정에 관여되는 겨드랑앞접힘점 위치가 명확해야 할 것이다. 유방과 관련된 깊이 항목에서는 유방 바깥쪽점을 제외한 모든 깊이에서 직접 측정치가 높게 나타났는데 이는 피부 눌림에 의한 것으로 판단된다. 또 유방의 굴곡이 심한 유방아래길이와 유방아래 접힘선길이, 유방 안쪽점사이 간격은 굴곡에 의해 3차원 측정치가 직접 측정치보다 높게 나타나 유방에 대한 3차원 측정법이 일반화되기 위해서는 다양한 유방유형에 따른 측정치의 변화를 연구할 필요가 있다.
