Information Base Procedures for Generation of Synthetic Thermal Scenes.
ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MS ENVIRONMENTAL LAB
Pagination or Media Count:
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.
