Abstract

The purpose of this paper is to propose a service system for a digital hologram video, which has not been published yet. This system assumes the existing service framework for 2-dimensional or 3-dimensional image/video, which includes data acquisition, processing, transmission, reception, and reconstruction. This system includes acquisition of color and depth image pairs from a image acquisition system with vertical rigs, rectification of acquired image pairs and generating digital hologram. Also it is designed to reduce the CGH (computer-generated hologram) generation time to 1/3. It also includes some additional and optional functions such as watermarking, compression, and encryption.

본 논문은 디지털 홀로그램 비디오를 서비스할 수 있는 서비스 시스템을 제안하는 것을 목적으로 한다. 이 시스템은 현존하는 2차원 또는 3차원 영상/비디오를 서비스하는 시스템의 프레임, 즉 데이터 획득, 처리, 전송, 수신, 복원의 과정을 그대로 따른다고 가정한다. 이 시스템은 수직 리그로부터 획득한 영상을 보정하는 전처리 과정을 수행하고, 시청자의 시점에 해당하는 가상 시점의 영상을 생성하고 홀로그램을 생성한다. 이전 연구에서 구현하지 못한 홀로그램에 대한 신호처리 요소들을 추가하고 성능을 개선하였다. 본 논문에서는 GPU를 늘리면서 이전 버전[25]의 홀로그램 생성시간을 1/3로 감소 시켰고 추가적으로 홀로그램의 압축, 워터마킹, 암호화 모듈을 추가하였다.
