This article presents a method to calibrate the optical imaging process of a focused plenoptic camera. At first, the concept of a focused plenoptic camera is presented, where the synthesis of images from the recorded light-field is described. It is …
In this article we present a method for 3D segmentation which is optimized for the recordings of a focused plenoptic camera. Since, caused by the imaging concept of a plenoptic camera, depth information is only received for regions of high contrast …
In this article we introduce new methods for the calibration of depth images from focused plenoptic cameras and validate the results. We start with a brief description of the concept of a focused plenoptic camera and how from the recorded raw image a …
This paper presents a novel system for 3D scene reconstruction and obstacle detection for visually impaired people, which is based on Microsoft Kinect. From the depth image of Kinect a 3D point cloud is calculated. By using both, the depth image and …
Dieser Artikel beschreibt ein System zur 3D-Rekonstruktion der Umgebung und zur Hinderniserkennung für blinde Personen. Basierend auf einer Microsoft Kinect wurden Algorithmen zur 3D-Rekonstruktion entwickelt. Diese Algorithmen realisieren eine …
In diesem Artikel wird zunächst die Berechnung der Tiefeninformation in einer fokussierten plenoptischen Kamera dargestellt. Hierbei wurden Eigenschaften der Tiefenauflösung erstmals analytisch beschrieben. Anschließend werden Kalibriermethoden …
