Abstract

The present invention provides a true-scale, coordinate-matched, linked in real-time, dual three-dimensional/two-dimensional visual display/viewer. The display simultaneously shows a 3D digital image and an associated 2D digital image of a selected drawing. The display of the present invention allows a user to visualize an asset'"'"'s location, surrounding environment and hazards and true scale structural details for interior or external structural scenes. Using the display and associated tools, the user can obtain real-time information of an environment, true-scale measurement, plan ingress/egress paths, shortest paths between points and the number of doorways in a structure and track objects within the displayed environment. The intelligence gained using the tools and 3D/2D display may be used and further manipulated by a single user or may be distributed to other users.

Claims

1-15. -15. (canceled)

16. A method of tracking assets within a structure using a digital viewer in which the digital viewer includes a two dimensional display means displaying a two dimensional digital image of a scanned paper document of a structure, scale information of the paper document being embedded in a header of the two dimensional digital image, wherein the improvement comprises:

displaying a three dimensional rendering of said two dimensional digital image in a three dimensional display means, said three dimensional rendering having a three dimensional coordinate system, said two dimensional digital image having a two dimensional coordinate system, said two dimensional coordinate system being matched to said three dimensional coordinate system forming a common coordinate system;

providing a receiver location about the structure; and

providing an asset with a receiving/transmitting device;

wherein location of said asset within said structure can be detected on said common coordinate system, and

wherein said two dimensional digital image is linked in real-time and coordinate matched with said three dimensional rendering.

17. The method of claim 16, wherein coordinates of said location is determined using a triangulation method on said digital viewer.

18. The method of claim 16, wherein coordinates of said location is determined using a multilateration method on said digital viewer.

19. The method of claim 16, wherein the receiving/transmitting device is a radio transmitter and receiver device.

20. The method of claim 16, wherein the receiving/transmitting device is a GPS device.

21. The method of claim 20, wherein the GPS device has a GPS coordinate system and a GPS scale, said GPS coordinate system and said GPS scale being translated to align with the common coordinate system.

22. (canceled)
