Patent Images
1. A computer implemented method of registering sensor imagery onto synthetic terrain, comprising the steps of:
- (a) accepting a sensor image having sensor image data;
(b) registering the sensor image data;
(c) orthorectifying the registered sensor image data;
(d) calculating overlay data relating the registered and orthorectified sensor image data to geographical references;
(e) converting the registered and orthorectified image data into a texture; and
(f) electronically draping the texture over synthetic terrain using the overlay data to provide a three dimensional terrain rendering.

Abstract
A method and apparatus for registering sensor imagery onto synthetic terrain is disclosed. The method comprises the steps of accepting a sensor image having sensor image data, registering the sensor image data, orthorectifying the registered sensor image data, calculating overlay data relating the registered and orthorectified sensor image data to geographical references, converting the registered and orthorectified image data into a texture, and draping the texture over synthetic terrain using the overlay data.
