Tracking in Unprepared Environments for Augmented Reality Systems
- Computers & Graphics
, 1999
"... Many Augmented Reality applications require accurate tracking. Existing tracking techniques require prepared environments to ensure accurate results. This paper motivates the need to pursue Augmented Reality tracking techniques that work in unprepared environments, where users are not allowed to mod ..."

Efficient, Causal Camera Tracking in Unprepared Environments
- Computer Vision and Image Understanding Journal
, 2005
"... This paper addresses the problem of tracking the 3D pose of a camera in space, using the images it acquires while moving freely in unmodeled, arbitrary environments. A novel feature-based approach for camera tracking is proposed, intended to facilitate tracking in on-line, time-critical applications ..."

Markerless Augmented Reality for Robots in Unprepared Environments
"... Augmented Reality (AR) can assist humans in understanding complex robot information, and improve Human and Robot Interaction (HRI). However, many restrictions are imposed by the underlying technology used and thus have limited current AR systems to operate in controlled or modified robot environment ..."

"Anywhere Augmentation": Towards mobile augmented reality in unprepared environments
- IN LOCATION BASED SERVICES AND TELECARTOGRAPHY, SERIES: LECTURE NOTES IN GEOINFORMATION AND CARTOGRAPHY
, 2007
"... We introduce the term „Anywhere Augmentation” to refer to the idea of linking location-specific computing services with the physical world, making them readily and directly available in any situation and location. This chapter presents a novel approach to „Anywhere Augmentation“ based on efficient h ..."

scene understanding abilities and the infeasibility of instrumenting the whole globe with a unified sensing and computing environment prevent progress in this area. Alternative approaches must be considered. We present a mobile augmented reality system for outdoor annotation of the real world. To reduce
Visual Registration For Unprepared Augmented Reality Environments
, 2003
"... Despite the increasing sophistication of augmented reality (AR) tracking technology, tracking in unprepared environments still remains an enormous challenge according to a recent survey. Most current systems are based on a calculation of the optical flow between the current and previous frames to ad ..."

Acoustic-Based Position Discrimination of a Moving Robot
, 2000
"... this paper is the navigation of autonomous mobile robots in unknown, unprepared environments. More precisely, the problem under investigation is the recognition of a revisited position in space and finding other previously visited positions relative to that position. The primary components of these ..."

Header for SPIE use Extending Augmented Reality with Natural Feature Tracking
"... In traditional vision-based Augmented Reality tracking systems, artificially-designed fiducials (or landmarks) have been used as camera tracking primitives. The 3D positions of these fiducials should be pre-calibrated, which imposes limitations in ranges of tracking view. Fortunately, the advance of ..."

of computer vision technologies combined with new point position estimation technology enable natural features to be detected, tracked, and calibrated to be used as camera tracking primitives. This paper describes how these technologies are used to track in an unprepared environment for Augmented Reality.
Integrating the physical environment into mobile remote collaboration
- In Proceedings of the 14th international conference on Human-computer interaction with mobile devices and services, ACM
"... We describe a framework and prototype implementation for unobtrusive mobile remote collaboration on tasks that involve the physical environment. Our system uses the Augmented Reality paradigm and model-free, markerless visual tracking to facilitate decoupled, live updated views of the environment an ..."
