Abstract

Real-time 360 VR (Virtual Reality) stereo image acquisition technique based on game engine was proposed. However, GPU (Graphics Processing Unit) resource is not fully utilized due to bottlenecks. In this paper, we propose an improved GPU scheduling technique to solve the bottleneck of the existing technique and measure the performance of the proposed technique using the sample games of the commercial game engine. As a result, proposed technique showed an improvement of performance up to 70% and usage of GPU resources more evenly compared existing technique.

게임 엔진을 기반으로 하는 실시간 360 VR(Virtual Reality) 스테레오 영상 획득 기술이 제안되었으나, 병목 현상이 발생하여 GPU(Graphics Processing Unit)의 성능을 충분히 활용하지 못 하고 있다. 본 논문에서는 기존에 제안된 실시간 360 VR 스테레오 영상 획득 기술의 병목 현상을 해결할 수 있도록 새로운 GPU 스케줄링 기법을 제안하고, 게임 엔진의 샘플 게임을 이용하여 제안하는 기법의 성능을 측정하였다. 측정 결과 기존에 제안된 기법보다 최대 약 70%의 성능 향상을 보였으며, GPU 자원이 좀더 균등하게 사용됨을 보였다.
