3d Content Capturing and Reconstruction Using Microsoft Kinect Depth Camera 3d Content Capturing and Reconstruction Using Microsoft Kinect Depth Camera

The main motivation behind this thesis was to create a new method of interaction between the physical and virtual space. The object was set to be achieved by creating a 3D-scanner capable of producing 360-degrees scans of real world objects to be visualized and used inside virtual spaces. The implementation of this objective began by conducting a background research about the existing methods f...

Camera Arrangement in Visual 3D Systems using Iso-disparity Model to Enhance Depth Estimation Accuracy

In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity surfaces provides an efficient way to estimate the depth estimation uncertainty which ...

Camera parameters estimation for 3D-Based Synthesis and 3D Reconstruction

In this paper, we propose a new camera calibration method for the 3D-based image synthesis and 3D reconstruction. We improve the problem as changing the principle point for obtaining the linear equation. According to the error rate, we adapt the non-linear method that minimizes the intrinsic parameters. Namely, it minimizes the intrinsic parameters error with maintaining the computational conci...

Depth Estimation for Mobile Robot Using Single Omnidirectional Camera System

Described here is a new method for depth estimation using a single omnidirectional visual sensor embedded on an autonomous mobile robot. This work is part of an on-going research project to study the visual guidance of autonomous robots. The method is based on a vertically aligned omnistereo configuration and laws of reflection applied on a geometric optics field. The proposed system yields a c...
