Image Compositing System using Omni-Directional Illumination

Automatic Image Stabilization for Omni-directional systems

For the purpose of Augmented Multi-party Interaction Project (AMI), an image stabilization of the meeting recordings is proposed. The mobile catadioptric system is usually prone to vibrations, which cause the distortion in the transformed panoramic image. The goal is to find proper parameters of the mirror border to image stabilization. Fast method with sub-pixel precision is needed. This paper...

Real-Time Motion Tracking System using Omni-Directional PTZ Camera

Mobile Robot Navigation using Omni directional Vision

This paper addresses the problem of autonomous mobile ro bot navigation in a simple indoor environment We present a system which combines the paradigm of visual servoing with appearance based methods The only sensory information available to the robot comes from an omni directional vision camera The geometry of our system which uses a spherical mirror is presented Our algorithm relies on a sequ...

Scalable Rotational Registration of Omni-Directional Image Networks

We describe a linear-time algorithm that recovers absolute, scene-relative camera orientations for networks of thousands of terrestrial images spanning hundreds of meters, in outdoor urban scenes, under uncontrolled lighting. The algorithm requires no human input or interaction, and produces orientation estimates globally consistent to roughly 0.1◦ (2 milliradians) on average, or about two pixe...

Omni-directional Visual Navigation

This paper considers a method for the visual-based navigation of a mobile robot in an indoor environment. The sole sensor used is an omni-directional camera. Navigation is achieved by combining appearance based methods and visual servoing. A database of omni-directional images is obtained during a training stage. This database maps the environment in a topological sense. Since the image set is ...
