On the Hybrid Aid-Localization for Outdoor Augmented Reality Applications

by I. M. Zendjebil, F. Ababsa, J-y. Didier, M. Mallem - In proc. Of ACM Symposium on Virtual Reality Software and Technology (VRST’08 , 2008
"... In mobile outdoor augmented reality applications, accurate localization is critical to register virtual augmentations over a real scene. Vision-based approaches provide accurate localization estimates but are still too sensitive to outdoor conditions (brightness changes, occlusions, etc.). This draw ..."

Tracking Hybrid Tracking for Outdoor Augmented Reality Applications

by unknown authors
"... Augmented reality applications use computer-generated virtual scenes to enhance (or augment) the actual scene viewed by the user with additional information. AR systems are used in the medical, entertainment, and military fields, as well as in engineering design. They enrich human perception and fac ..."

Hybrid Tracking System for Outdoor Augmented Reality

by Stelian Persa, Pieter Jonker - τ1] ◦S1 , 2000
"... Almost all Augmented Reality (AR) systems work indoors. Outdoor AR systems offer the potential for new application areas. The biggest single obstacle to building effective AR systems is the lack of accurate wide-area sensors for trackers that report the locations and orientations of objects in an en ..."

Exploring MARS: Developing Indoor and Outdoor User Interfaces to a Mobile Augmented Reality System

by Tobias Höllerer, Steven Feiner, Tachio Terauchi, Gus Rashid, Drexel Hallaway - Computers and Graphics , 1999
"... We describe an experimental mobile augmented reality system (MARS) testbed that employs different user interfaces to allow outdoor and indoor users to access and manage information that is spatially registered with the real world. Outdoor users can experience spatialized multimedia presentations tha ..."

Making Augmented Reality Work Outdoors Requires Hybrid Tracking

by Ronald T. Azuma, Bruce R. Hoff, Howard E. Neely Iii, Ronald Sarfaty, Michael J. Daily, Gary Bishop, Vern Chi, Greg Welch, Ulrich Neumann, Suya You, Rich Nichols, Jim Cannon , 1998
"... Developing Augmented Reality systems that work outdoors, rather than indoors in constrained environments, will open new application areas and motivate the construction of new, more general tracking approaches. Accurate tracking outdoors is difficult because we have little control over the environmen ..."

A Hybrid Registration Method for Outdoor Augmented Reality

by Kiyohide Satoh, Mahoro Anabuki, Hiroyuki Yamamoto, Hideyuki Tamura , 2001
"... In this paper, a registration method for outdoor wearable AR systems is described. Our approach is based on using a high precision gyroscope, which can measure 3DOF angle of head direction accurately, but with some drift error. We solved the drift problem with a vision-based drift compensation algor ..."

Registration for outdoor augmented reality applications using computer vision techniques and hybrid sensors

by Reinhold Behringer - In Proceedings of Virtual Reality , 1999
"... Registration for outdoor systems for Augmented Reality (AR) cannot rely on the methods developed for indoor use (e.g., mag-netic tracking, fiducial markers). Although GPS and the earth’s magnetic field can be used to obtain a rough estimate of posi-tion and orientation, the precision of this registr ..."
