초록
컴퓨터 그래픽스 분야에서 저가의 RGB-D 카메라로 촬영된 색상 및 깊이 영상을 이용한 사람 및 사물을 3차원 모델로 복원하는 문제는 오랫동안 이를 해결하기 위하여 다양한 연구들이 진행되어왔다. 저가의 RGB-D 카메라로 촬영된 색상 및 깊이 영상은 3차원 공간에서 점 구름 형태로 다루어지며, 이는 연속적인 3차원 공간상에 이산적인 값을 대응시키기 때문에 다면체 모델을 이용한 렌더링에 비해 추가적인 표면 재구성 과정이 필요하다. 본 논문에서는 다면체 모델이 아닌 점 구름을 시각화하기 위한 효과적인 광선 추적 기반 렌더링 기법을제안한다. 특히 프로세서의 발열과 배터리 문제로 인한 모바일 환경에서의 제한적인 성능에서도 효과적인 렌더링 기법으로서의 가능성을 보인다.
Abstract
The problem of reconstructing three-dimensional models of people and objects from color and depth images captured by l ow-cost RGB-D cameras has long been an active research area in computer graphics. Color and depth images captured by l ow-cost RGB-D cameras are represented as point clouds in three-dimensional space, which correspond to discrete values in a continuous three-dimensional space and require additional surface reconstruction compared to rendering using polygonal mo dels. In this paper, we propose an effective ray-tracing based technique for visualizing point clouds rather than polygonal m odels. In particular, our method shows the possibility of an effective rendering method even in mobile environment which h as limited performance due to processor heat and lack of battery.
