Abstract

The increased demand for multi-resolution displays of simulated scene data for aircraft training or mission planning has led to a need for digital databases of 3-dimensional topography and geographically positioned objects. This data needs to be at varying resolutions or levels of detail as well as be positionally accurate to satisfy close-up and long distance scene views. The generation and maintenance processes for this type of digital database requires that relative and absolute spatial positions of geographic and cultural features be carefully controlled in order for the scenes to be representative and useful for simulation applications. Autometric, Incorporated has designed a modular Analytical Image Matching System (AIMS) which allows digital 3-D terrain feature data to be derived from cartographic and imagery sources by a combination of automatic and man-machine techniques. This system provides a means for superimposing the scenes of feature information in 3-D over imagery for updating. It also allows for real-time operator interaction between a monoscopic digital imagery display, a digital map display, a stereoscopic digital imagery display and automatically detected feature changes for transferring 3-D data from one coordinate system's frame of reference to another for updating the scene simulation database. It is an advanced, state-of-the-art means for implementing a modular, 3-D scene database maintenance capability, where original digital or converted-to-digital analog source imagery is used as a basic input to perform accurate updating.
