A compact and one-shot light field capturing system is proposed in this paper. The overall studio consists of one commercialized light field camera and a couple of reflective plates. Without mechanical movement, light field from back and side parts of subjects is captured through a pair of mirrors. Owing to relatively large depth of focus of light field camera, a subject and its reflected images can be recorded on an image sensor. A position and orientation of mirrors are analyzed to optimize 360-degree light field recording. Experimental results are shown to verify the proposed recording system.","PeriodicalId":263258,"journal":{"name":"Rundbrief Der Gi-fachgruppe 5.10 Informationssystem-architekturen","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125461685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
