چکیده
초박형 라이트필드 카메라 시스템은이미지 센서 위에 렌즈 어레이를 부착하는 방식으로 만들어진다. 이러한 라이트 필드 카메라는 하나의이미지 센서를 여러 개의 sub-aperture가 나눠쓰는 되어있어 개별 이미지의 분해능이 낮으며, sub-aperture 이미지들을 융합해 추가적인 분해능 향상이 수행되어야 한다. 본 연구에서는 시스 템을 개발했으며, 개발된 시스템을위한 실시간 향상 알고리즘을 개발, 실험을 통해 검증했다. 두께 2mm, 24개(6 × 4)의 551 해상도의 sub-aperture로 구성되어 있으며, 임베디드 컴퓨팅 보드를 사용해 휴대가가능하도록 제작되었다. 알고리즘은임베디드 보드의 GPU에서 병렬처리를 라플라시안 피라미드 기반의이미지 융합 수행한다. 검증한 결과로, 개발 시스템은 MTF50값이 평균 35% 정도 개선되었으며, 10.65fps의 처리속도로 처리가가능함을 확인했다.

Recent progress on multi-domain optimization for ultra-thin cameras
Conventional imaging systems can suffer from significant aliasing and/or blur distortions when the detector array in the focal plane under-samples the image. We propose to address this problem by engineering the optical PSF of the imaging system followed by electronic post-processing to minimize the overall distortions. The optical PSF of the candidate imaging system is modified by placing a ph...
متن کاملA Real-Time Distributed Light Field Camera
We present the design and implementation of a real-time, distributed light field camera. Our system allows multiple viewers to navigate virtual cameras in a dynamically changing light field that is captured in real-time. Our light field camera consists of 64 commodity video cameras that are connected to off-the-shelf computers. We employ a distributed rendering algorithm that allows us to overc...
متن کاملReal-time 3D light field transmission
Although capturing and displaying stereo 3D content is now commonplace, information-rich light-field video content capture, transmission and display are much more challenging, resulting in at least one order of magnitude increase in complexity even in the simplest cases. We present an end-to-end system capable of capturing and real-time displaying of high-quality light-field video content on va...
متن کاملWearable Cameras for Real-Time Activity Annotation
Google Glass has potential to be a real-time data capture and annotation tool. With professional sports as a use-case, we present a platform which helps a football coach capture and annotate interesting events using Google Glass. In our implementation, an interesting event is indicated by a predefined hand gesture or motion, and our platform can automatically detect these gestures in a video wi...
