Abstract

This study aims to develop a stereoscopic image authoring tool to effectively produce e-Book content that enhances user's sense of immersion in 3D environments. The proposed authoring tool consists of three core systems; 3D object editing, stereoscopic image, and image media production systems. First, the object editing system arranges and produces diverse objects that constitute virtual 3D spaces to fit the purpose of the content. In this case, commercial graphic authoring tools are utilized to design efficient data structures that can include produced external models. In addition, the material and textures of objects are made to be revisable and editable into the form wanted by the user. Thereafter, a stereoscopic image system will be implemented to produce the generated virtual scenes into stereoscopic images. This study uses the Anaglyph method so that the user can implement and use stereoscopic image scenes more easily. This method include functions to change the color of stereo cameras and control depth scaling. Finally, an image media production system will be implemented that will enable producing the produced stereoscopic images into single images or videos so that they can be effectively utilized in e-Book content.

본 논문은 3차원 환경에서 사용자의 몰입감을 높여주는 e-Book 콘텐츠를 효과적으로 제작하기 위한 입체 영상 저작도구를 개발한다. 제안하는 저작도구는 3차원 객체 편집, 입체 영상 그리고 영상 미디어 제작의 3가지 핵심 시스템으로 구성된다. 우선 객체 편집 시스템은 3차원 가상공간을 구성하는 다양한 객체들을 콘텐츠의 목적에 맞게 배치, 제작한다. 이때 상용 그래픽 저작도구를 활용하여 제작된 외부 모델들을 포함할 수 있는 효율적인 데이터 구조를 설계한다. 여기에 객체의 재질, 텍스쳐 등을 사용자가 원하는 형태로 수정, 편집이 가능하도록 한다. 그리고 셍성된 가상 장면을 입체 영상으로 제작하기 위한 입체 영상 시스템을 구현한다. 본 연구는 애너그리프 방법을 사용하여 사용자가 보다 쉽게 입체 영상 장면을 구현하고 사용할 수 있도록 한다. 이는 양안 카메라의 색상 변경 및 입체감 조절 기능 등을 포함한다. 마지막으로 제작된 입체 영상을 e-Book 콘텐츠에 효과적으로 활용 가능하도록 단일 영상 또는 동영상으로 제작하여 활용할 수 있는 영상 미디어 제작 시스템을 구현한다.
