    An important problem for augmented reality is registration error. No system can be perfectly tracked, calibrated or modeled. As a result, the overlaid graphics are not aligned perfectly with objects in the physical world. This can be distracting, annoying or confusing. In this paper, we propose a method for mitigating the effects of registration errors that enables application developers to build ... View full abstract»

    We are proposing an optical see-through head-worn display that is capable of mutual occlusions. Mutual occlusion is an attribute of an augmented reality display where real objects can occlude virtual objects and virtual objects can occlude real objects. For a user to achieve the perception of indifference between the real and the virtual images superimposed on the real environment, mutual occlusio... View full abstract»

    In this paper, we propose a new way of augmenting our environment with information without making the user carry any devices. We propose the use of video projection to display the augmentation on the objects directly. We use a projector that can be rotated and in other ways controlled remotely by a computer, to follow objects carrying a marker. The main contribution of this paper is a system that ...

    This paper presents a set of technologies which enable robust, accurate, high resolution augmentation of live video, delivered via a tablet PC to which a video camera has been attached. By combining several technologies, this is achieved without the use of contrived markers in the environment: An outside-in tracker observes the tablet to generate robust, low-accuracy pose estimates. An inside-out ... View full abstract»

  • Combining edge and texture information for real-time accurate 3D camera tracking

    We present an effective way to combine the information provided by edges and by feature points for the purpose of robust real-time 3-D tracking. This lets our tracker handle both textured and untextured objects. As it can exploit more of the image information, it is more stable and less prone to drift that purely edge or feature-based ones. We start with a feature-point based tracker we developed ... View full abstract»

  • Handling uncertain sensor data in vision-based camera tracking

    A hybrid approach for real-time markerless tracking is presented. Robust and accurate tracking is obtained from the coupling of camera and inertial sensor data. Unlike previous approaches, we use sensor information only when the image-based system fails to track the camera. In addition, sensor errors are measured and taken into account at each step of our algorithm. Finally, we address the camera/... View full abstract»

  • Display-relative calibration for optical see-through head-mounted displays

    Optical see-through head-mounted displays (OSTHMDs) have many advantages in augmented reality application, but their utility in practical applications has been limited by the complexity of calibration. Because the human subject is an inseparable part of the eye-display system, previous methods for OSTHMD calibration have required extensive manual data collection using either instrumentation or man...

  • Automated initialization for marker-less tracking: a sensor fusion approach

    We introduce a sensor fusion approach for automated initialization of marker-less tracking systems. It is not limited in tracking range and working environment, given a 3D model of the objects or the real scene. This is achieved based on a statistical analysis and probabilistic estimation of the uncertainties of the tracking sensors. The explicit representation of the error distribution allows the...

    This paper describes a calibration method of markers which are used for registration in MR applications. There have been many vision-based approaches proposed as registration methods in MR. When multiple markers are utilized in a vision-based method, it is necessary that the geometric information of the marker arrangement such as their positions and orientations be known in advance.

    We introduce a method to imperceptibly embed arbitrary binary patterns into ordinary color images displayed by unmodified off-the-shelf digital light processing (DLP) projectors. The encoded images are visible only to cameras synchronized with the projectors and exposed for a short interval, while the original images appear only minimally degraded to the human eye. To achieve this goal, we analyze... View full abstract»

    We present a complete system architecture for fully automated markerless augmented reality (AR). The system constructs a sparse metric model of the real-world environment, provides interactive means for specifying the pose of a virtual object, and performs model-based camera tracking with visually pleasing augmentation results. Our approach does not require camera pre-calibration, prior knowledge ... View full abstract»

    Many tracking systems utilize collections of fiducial markers arranged in rigid configurations, called tracking probes, to determine the pose of objects within an environment. In this paper, we present a technique for designing tracking probes called the viewpoints algorithm. The algorithm is generally applicable to tracking systems that use at least three fiduciary marks to determine the pose of ... View full abstract»

    We present VITA (visual interaction tool for archaeology), an experimental collaborative mixed reality system for offsite visualization of an archaeological dig. Our system allows multiple users to visualize the dig site in a mixed reality environment in which tracked, see-through, head-worn displays are combined with a multi-user, multi-touch, projected table surface, a large screen display, and ...
