Embodiment Construction

[0025]The situation awareness system described herein makes use of Augmented Reality (AR) technology to provide the necessary view to the user. AR is like Virtual Reality, but instead of using completely artificial images (e.g. maps or 3D models), AR superimposes 3D graphics on a view of the real world. A very simple example of AR is used in football games to show the first down with a yellow line. An example of an AR system that can be employed is one described in the examples of U.S. application Ser. No. 11 / 441,241 in combination with the present disclosure.

[0026]An AR visualization system comprises: a spatial database, a graphical computer, a viewpoint tracking device, and a display device.

[0027]The working principle of an Augmented Reality system is described below. A display device that displays dynamic images corresponding to a user's view is tracked. That is, the display's position and orientation are measured by a viewpoint tracking device. A spatial database and a graphical...

Abstract

An augmented reality system provides enhanced situational information to personnel located within an environment. A tracking system obtains viewpoint information corresponding to a real-time view of said environment. A processing system receives information from one or more sensors. Information includes sensor location information and status information about the environment and personnel therein. The processing system generates graphics using the sensor location information and the viewpoint information. Graphics include visual representations of said status information. A display displays the generated graphics on a display at a supervisor station that is outside of said environment such that graphics are superimposed on the real-time view.
