System and method for three-dimensional visualization of geographical data

摘要

A method of using a computer to generate virtual autostereoscopic images from a three-dimensional digital data set is provided. The method includes establishing a first point of view and field of view of a subject volume including a region of interest. The method also includes reading at least one scene parameter associated with the field of view of the subject volume. The method also includes determining a second point of view offset some distance and along some vector from the first point of view based on a value derived from at least one scene parameter. The method also includes generating and storing images and relevant metadata from said first and second points of view. The method also includes displaying the stored images by alternatingly displaying stored images from said first and second points of view. The method further includes performing one or more transformations on the alternatingly displayed images.

1. A method of using a computer to generate virtual autostereoscopic images from a three-dimensional digital data set, comprising:
establishing a first point of view comprising a first field of view of a subject volume including a region of interest; reading a scene parameter associated with the first field of view of the subject volume; determining a second point of view offset some distance and along some vector from the first point of view based on a value derived from the scene parameter wherein said second point of view comprises a second field of view that at least partially overlaps the first field of view and wherein said first and second points of view create a view plane perpendicular to orthogonal views of the subject volume; generating and storing images and relevant metadata from said first and second points of view; determining a critical alignment transformation for at least one stored image based on the offset distance and an angle of convergence of at least one of the first point of view and the second point of view; performing a transformation using the critical alignment transformation on the at least one stored image that brings some desired point in the region of interest of the at least one stored image into a converged critical alignment wherein the region of interest appears three-dimensional to a viewer on a standard two-dimensional unaided display; and displaying the stored images by alternatingly displaying the transformed images from said first and second points of view at a rate of between 2 and 60 cycles per second.
