Real time video perspective digital map display method

摘要

A digital system for producing a real-time visual display in perspective of the terrain over which an aircraft is passing on the basis of compressed digital data stored on a cassette tape includes a perspective processor for transforming the addresses of points in a two-dimensional data pattern to the addresses these points occupy in a three-dimensional scene and for a filing in points between the transformed points to provide a complete display of the terrain in perspective.
