Battlefield Visualization and Database Creation System Using One Meter Terrain

摘要

Integration of battlefield simulation systems in operational scenarios requires the accurate calculation of concealment, cover, and detectability to properly enhance the soldier's performance and effectiveness on the battlefield. Measurement and visualization of tactical battlefield features requires the generation of metrically accurate terrain databases at high resolution over large areas. Systems capable of generating and utilizing such data have been expensive and slow. A low cost PC based system has been designed to address the generation and utilization of one-meter resolution terrain in large area, tactical battlefield simulations. The architecture and development is designed to incrementally approach the performance of human vision systems. Technical features described include an efficient all integer based ray trace algorithm, which allows video realistic battlefield visualization from girded sensor derived data, a multi-theme variable resolution ground descriptor database, real time rendering table to accommodate season, lighting and sensor variations and tools for rapid in field data correction and updating. The system is called Perspective View Nascent Technologies (PVNT). The package has been developed as a research project by the Naval Postgraduate School, TRADOC, OTC Ft. Hood and Nascent Systems Inc.
