High-Performance Wide-Area Optical Tracking: The HiBall Tracking System
Since the early 1980s, the Tracker Project at the University of North Carolina at Chapel Hill has been working on wide-area head tracking for virtual and augmented environments. Our long-term goal has been to achieve the high performance required for accurate visual simulation throughout our entire laboratory, beyond into the hallways, and eventually even outdoors. In this article, we present r...
متن کاملReal Time Automatic Object Tracking by Pan-Tilt-Zoom cameras in an IP-Surveillance System
Pan-tilt-zoom (PTZ) cameras are one of the advanced security cameras in the market. These cameras have the ability to cover a very far field and can acquire high resolution of images. These cameras are deployed mainly for perimeter surveillance applications where the security guards have to monitor the intruders from a long distance. Although there are intrinsic advantages of using pan-tilt-zoo...
متن کاملWide Area Motion Tracking Using Consumer Hardware
In this paper, we present a wide area tracking system based on consumer hardware and available motion capture modules and middleware. We are using multiple depth cameras for human pose tracking in order to increase the captured space. Commercially available cameras can capture human movements in a nonintrusive way, while associated software-modules produce pose information of a simplified skele...
متن کاملMechanically assisted liquid lens zoom system for mobile phone cameras
Camera systems with small form factor are an integral part of today’s mobile phones which recently feature auto focus functionality. Ready to market solutions without moving parts have been developed by using the electrowetting technology. Besides virtually no deterioration, easy control electronics and simple and therefore cost-effective fabrication, this type of liquid lenses enables extremel...
متن کاملZoom Tracking
In this paper we present a new active vision technique called zoom tracking. Zoom tracking is the continuous adjustment of a camera’s focal length, to keep a constantsized image of an object moving along the camera’s optical axis. Two methods for performing zoom tracking are presented: a closed-loop visual feedback algorithm based on opticaljlow, and use of depth information obtained from an au...
