Abstract

Product modeling technology for graphics is rapidly developing. And 3D data application and usability are increasing.modeling of product design is a very important factor in constructing. 3D modeling in product design takes a lot of production time. Recently, the reverse design method is very useful because of application of 3D data and shortening of production time. In this study, first, 3D point cloud and mesh data are generated using photographs based on image data. The second is to modify the design and the third is to make the prototype with the 3D printer. This product design and production process suggests the utilization and possibility of image data, the shortening of 3D modeling production time and efficient processes. Also, the product design process proposes a model of a new product development system to adapt to the production environment.

그래픽스 분야의 제품모델링 제작기술은 급속하게 발전하고 있고 3차원 데이터 응용과 활용성은 계속 증가하고 있다. 제품디자인 제작에 있어 3차원 모델링 제작에는 많은 시간이 소요된다. 최근 역설계 방식은 3D 데이터의 응용과 제작시간단축으로 활용성이 크다. 본 연구는 영상데이터 기반으로 포토메트리를 이용하여 3차원 포인트 클라우드 및 메쉬 데이터를 추출하고 이를 응용하여 제품의 1차 시안을 제작한다. 디자인 수정에 중점을 두어 2차 시안이 제작되었으며 3차 시제품 제작을 위한 3D 프린팅 작업을 진행한다. 이러한 제품디자인 제작과정에서 영상데이터의 활용과 가능성 및 3D 모델링 제작시간의 단축, 효율적인 프로세스를 제시한다. 또한 제품디자인 환경변화에 대응하기 위한 신제품 개발 프로세스 시스템의 모델을 제안한다.
