Hybrid Tracking System for Outdoor Augmented Reality
نویسندگان
چکیده
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 environment. Active (sensor-emitter) tracking technologies require powered-device installation, limiting their use to prepared areas that are relative free of natural or man-made interference sources. The hybrid tracker combines rate gyros and accelerometers with compass and tilt orientation sensor and GPS system. Sensor distortions, delays and drift required compensation to achieve good results. The measurements from sensors are fused together to compensate for each other's limitations. Analysis and experimental results demonstrate the system effectiveness.

A Hybrid Line-based Tracking System for Outdoor Environments
We describe a hybrid tracking system for outdoor augmented reality applications in this paper. There are two main contributions of the proposed system: 1) It makes use of naturally occurring line features to recover 6ODF pose; 2) A high precision gyro is used to track 2D lines across frames for large inter-frame motions. The proposed system has been tested for outdoor augmented reality applicat...

This paper describes a new hybrid tracking system that integrates standard outdoor augmented reality trackers with a low cost indoor tracker based on the use of fiducial markers. We use multiple cameras, separate orientation sensing, and scene graph integration to improve on similar previous systems. This hybrid tracker allows applications to operate within large indoor and outdoor environments...
متن کاملTracking in unprepared environments for augmented reality systems
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 modify the real environment, such as in outdoor applications. Accurate tracking in such situations i...

متن کاملAugmented Reality Tracking in Natural Environments
Tracking, or camera pose determination, is the main technical challenge in creating augmented realities. Constraining the degree to which the environment may be altered to support tracking heightens the challenge. This paper describes several years of work at the USC Computer Graphics and Immersive Technologies (CGIT) laboratory to develop self-contained, minimally intrusive tracking systems fo...
