High-Performance Wide-Area Optical Tracking: The HiBall Tracking System

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...

Development of Wide-Area Tracking System for Augmented Reality

In this study, two types of marker-based tracking systems for Augmented Reality were developed: a tracking system using line markers and a tracking system using circular markers. Both markers were designed for use inside buildings such as nuclear power plants, which are very complicated and in which it is difficult to paste many large markers. To enlarge the area in which tracking is available ...

A Wide Area Tracking System for Vision Sensor Networks

Advanced Inertial-Optical Tracking System for Wide Area Mixed and Augmented Reality Systems

InterSense is introducing a vastly improved version of its wide-area tracking inertia-optical tracking system (IS-1200 VisTracker). The new VisTracker technology is has several enhancements including device miniaturization, an embedded image processor, improved optics, a higher resolution imaging CMOS monochrome sensor, power reduction, and ruggedization. A review of the IS-1200 architecture an...

Human Activity Tracking for Wide-Area Surveillance

We present a method for tracking and identifying moving persons from video images taken by a fixed field-ofview camera. Specifically, we have developed a system to first track moving persons in a given scene and generate color-based models of those persons to accomplish identification. The tracking is non-invasive meaning that it does not require persons to wear any particular electronics or cl...
