본 논문에서는 3차원 디스플레이 시스템에서 다수의 중간 시점 영상을 실시간으로 생성할 수 있도록 GPU 기반의 고속 영상 합성기법을 제안하였으며 그에 대한 성능을 알아본다. 카메라의 기하 정보 및 참조 영상들의 깊이 정보를 이용하여 중간 시점 영상을 생성하였으며, 영상 합성 방법을 GPU에서 병렬 처리함으로써 고속화할 수 있었다. GPU를 효율적으로 다루기 위해 NVIDIA사의 CUDA(Compute Unified Device Architecture)$^TM$를 이용하였다. 제안한 기법은 CUDA의 SIMD(Single Instruction MUltiple Data) 구조를 사용하여 중간 영상 합성을 처리할 수 있도록 설계하였다. 본 논문은 고속 영상 합성에 중점을 두었고, 제안한 고속화 기법의 결과를 분석함으로써 다시점 3차원 디스플레이 시스템의 적용 가능성을 알아본다.
