Information Base Procedures for Generation of Synthetic Thermal Scenes.
Abstract
Procedures are being developed for computer generation of thermal images that depict realistic landscape perspective and are radiometrically correct. Digital three-dimensional (3-D) representations of thermal terrain conditions can be used for software and hardware in the loop testing by weapons system designers, developers, and evaluators. The procedure has four components: (a) environmental information bases that characterize the static and dynamic aspects of the landscape, (b) physics-based numerical thermal prediction models, (c) radiance prediction models, and (d) computer graphics system for generating a 3-D thermal landscape perspective. This report describes the information base content, structure, and analysis methods developed to store and access 3-D terrain, weather, physical, thermal, and spectral property data required to support all procedure components. Methods for characterizing and quantifying environmental information as a 3-D dynamic landscape; formatting, managing, and retrieving diverse environmental information for numerical modeling purposes; and analyzing terrain data are discussed.
