Conference Object Citation - WoS: 2Citation - Scopus: 2Çok Bakışlı 3b Geriçatımın Polarizasyon Görüntüleme Kullanımıyla İyileştirilmesi(Institute of Electrical and Electronics Engineers Inc., 2014) Ozan, Şükrü; Gümüştekin, ŞevketPerformance of stereo imaging methods, which are used to find depth information of a scene, can be adversely affected by surface reflection properties of subjects in the scene and possible change in relative camera and light source positions. In this study a catadioptric multiview imaging system, which is constructed by using planar mirrors, is proposed. Stereo matching problems which are caused by the specular reflections in the scene are highlighted and it is shown that those problems can be significantly alleviated by using polarization images.Conference Object Yapısal Aydınlatma Kullanarak Yüzeylerin Geometrik ve Yansıtıcılık Özelliklerinin Geri Çatımı(Institute of Electrical and Electronics Engineers Inc., 2015) Ozan, Şükrü; Gümüştekin, ŞevketIt is not possible to perform a robust and dense surface reconstruction for plain colored surfaces which have insufficient surface features, and for surfaces which have specularity effect because of the material nature by using traditional stereo imaging methods. The proposed surface scanner system in this work makes it possible to get a robust and dense surface reconstruction even for plain colored and/or semi glossy surfaces. Reflection properties of the surface material are also reconstructed to some extent by using the information gathered after scanning process. Moreover, the experimental results are shown.
