Depth Estimation from Micro Images of a Plenoptic Camera

This paper presents a method to calculate the depth values of 3D points by means of a plenoptic camera. Opposed to other approaches which use the totally focused image to detect points, we operate directly on the micro images taking thus advantage of …

Feature based RGB-D SLAM for a Plenoptic Camera

This paper presents a method to estimate the camera poses for images of a plenoptic camera. For this, a feature based RGB-D SLAM is used. A new method for matching the features between two images will be presented. Finally the result of the algorithm …

A Real-Time Depth Estimation Approach for a Focused Plenoptic Camera

This paper presents an algorithm for real-time depth estimation with a focused plenoptic camera. The described algorithm is based on pixel-wise stereo-observations in the raw image recorded by the plenoptic camera which are combined in a …

Filtering Probabilistic Depth Maps Received from a Focused Plenoptic Camera

This paper presents a filtering approach for semidense probabilistic depth map received from a focused plenoptic camera. In the probabilistic depth map each valid depth pixel contains, beside the depth value itself, a variance which gives a measure …

Establishing a Probabilistic Depth Map from Focused Plenoptic Cameras

In this paper we propose a novel method for depth estimation based on a single recording of a focused plenoptic camera. The presented algorithm is based on multiple stereo-observations within the multi-view micro images of the focused plenoptic …

Narrow Field-Of-View Visual Odometry Based on a Focused Plenoptic Camera

In this article we present a new method for visual odometry based on a focused plenoptic camera. This method fuses the depth datagained by a monocular Simultaneous Localization and Mapping (SLAM) algorithm and the one received from a focused …

Applying a Traditional Calibration Method to a Focused Plenoptic Camera

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 …

Edge Segmentation in Images of a Focused Plenotic Camera

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 …

Calibration and Accuracy Analysis of a Focused Plenoptic Camera

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 …

Kinect based 3D Scene Reconstruction

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 …
