Abstract

This paper describes an insole FFO(Functional Foot Orthosis) model for comfortable walking by considering weight distribution. There are many ways to make an insole FFO model such as using 3D computer graphics, or plaster manually. Thus, we proposed a standardized way to make an insole model, specifically called, robust and automatically personalized deformable insole model. Our proposed method showed 0.8cm average error compared between our proposed auto-deformable insole model and the other insole model manually deformed by experts. Therefore, our proposed method can be an efficient way to make a customized insole model with small error compared to the manually customized insole model.

본 논문은 인간이 직립 보행 시 무게의 분산을 고려하여 편안한 보행과 발목 교정을 할 수 있는 인솔 모델에 대한 연구를 진행하였다. 인솔 제작에 있어서 과거에는 많은 부분이 수작업으로 이루어 졌지만, 최근에는 3차원 컴퓨터 그래픽을 이용하여 모델을 생성해서 제작하려는 시도가 이루어지고 있다. 우리는 3차원 스캐너를 이용하여 발을 정밀하게 스캔하고, 스캔한 발 모델을 통해서 발과 인솔의 관계를 4개의 특징점을 이용하여 예측하였다. 이 예측된 인솔 모델은 3차원 프린터를 이용하여 인솔의 모양을 만들 수 있게 모델링 하였다. 이처럼 맞춤형 인솔 제작의 표준화된 방법을 제시함으로써 강인한 개인 맞춤형 자동 변형 인솔 모델을 제안하였다. 우리가 제안한 자동 인솔 변형 모델과 전문가가 생성한 인솔을 비교한 결과에서 평균 0.8cm의 오차율을 보이며, 아주 근소한 오차로 인솔 제작이 가능할 수 있다는 방법을 제시하였다.
