In 1960, R.E. Kalman published his famous paper describing a recursive solution to the discrete-data linear filtering problem. Since that time, due in large part to advances in digital computing, the Kalman filter has been the subject of extensive research and application, particularly in the area of autonomous or assisted navigation. The Kalman filter is a(More)
High-resolution Spatially Immersive Displays (SID) generally involve wide field of view (WFOV) image generation using multiple projectors. This paper describes a robust calibration and rendering method for projector based seamless displays using a video camera. It solves the basic problem of registering and blending overlap of two projections at a time. It(More)
To create an effective illusion of virtual objects coexisting with the real world, see-through HMD-based Augmented Reality techniques supplement the user's view with images of virtual objects. We introduce here a new paradigm, Spatially Augmented Reality (SAR), where virtual objects are rendered directly within or on the user's physical space. A key benefit(More)
We present an approach for automatic 3D reconstruction of outdoor scenes using computer vision techniques. Our system collects video, GPS and INS data which are processed in real-time to produce geo-registered, detailed 3D models that represent the geometry and appearance of the world. These models are generated without manual measurements or markers in the(More)
Despite the availability of high-quality graphics systems, architects and designers still build scaled physical models of buildings and products. These physical models have many advantages, however they are typically static in structure and surface characteristics. They are inherently lifeless. In contrast, high-quality graphics systems are tremendously(More)

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 environment and fewer resources available compared to an indoor(More)
Tracking systems determine the position and/or orientation of a target object, and are used for many different purposes in various fields of work. My focus is tracking systems in virtual environments. While the primary use of tracking for virtual environments is to track the head position and orientation to set viewing parameters, another use is body(More)
—The synchronized phasor measurement unit (PMU), developed in the 1980s, is considered to be one of the most important devices in the future of power systems. While PMU measurements currently cover fewer than 1% of the nodes in the U.S. power grid, the power industry has gained the momentum to advance the technology and install more units. However, with(More)
