Abstract

An imaging system includes a 3D database for storing data relating to three-dimensional site model images having a vantage point position and orientation when displayed. A 2D database stores data relating to a two-dimensional image that corresponds to the vantage point position and orientation for the three-dimensional site model image. Both the three-dimensional site model image and two-dimensional imagery are displayed typically on a common display A processor operative with the two-dimensional and three-dimensional databases and will create and display the three-dimensional site model image and two-dimensional imagery from data retrieved from the 2D and 3D databases and correlates and synchronizes the three-dimensional site model image and two-dimensional imagery to establish and maintain a spatial orientation between the images as a user interacts with the system.

Claims

a 3D database for storing data relating to a three-dimensional site model having vantage point positions and orientations when displayed;

a 2D database for storing data relating to two-dimensional images that correspond to vantage point positions and orientations for the three-dimensional site model;

a display for displaying both the three-dimensional site model image and two-dimensional imagery; and

a processor operative with the 2D and 3D databases and the display for creating and displaying the three-dimensional site model image and two-dimensional imagery from data retrieved from the 2D and 3D databases and correlating and synchronizing the three-dimensional site model image and two-dimensional imagery to establish and maintain a spatial orientation between the images as a user interacts with the system.

2. The imaging system according to claim 1, and further comprising a graphical user interface on which the three-dimensional side model and two-dimensional images are displayed.

3. The imaging system according to claim 1, and further comprising said three-dimensional site model image and said two-dimensional images such as a panoramic view obtained at an image collection point within a building interior and a floor plan image centered on the image collection point within the building interior.

4. The imaging system according to claim 3, wherein said processor is operative for rotating the panoramic image and updating the floor plan image with a current orientation of the panoramic image for purposes synchronizing said two-dimensional imagery with the three-dimensional site model image.

5. The imaging system according to claim 1, and further comprising a dynamic heading indicator that is displayed and synchronized to a rotation of the three-dimensional site model image.

6. The imaging system according to claim 1, wherein said processor is operative for updating at least one of said 2D and 3D databases based upon additional information obtained while a user interacts with an image.

7. The imaging system according to claim 1, wherein said 2D database comprises rasterized vector data.

8. The imaging system according to claim 1, wherein said 3D database comprises data for a Local Space Rectangular or world Geocentric coordinate system.

9. The imaging system according to claim 1, and further comprising an associated database operative with said 2D and 3D databases for storing ancillary data to the 2D database and 3D database and providing additional data that enhances the two and three dimensional data displayed during user interaction with the system.
