Paper Abstract

The problem of realistic, high-resolution, earth surface representation for real-time, rendered, video-quality perspective view generation has been approached by using a quantized rendering transform to code image measurements into physical surface modeling descriptors. This paper describes a physical earth surface model and approximates natural light energy scattering equations to derive a transform between photogrammetric measurements and model parameters. This transform was used to translate a 12 Gbyte, photo image, data base covering 400 sq km of Ft. Hunter Liggett, CA into a 1.2 Gbyte surface descriptor file. A prototype transputer-based parallel processing system is also presented. The system uses the rendering transform to calculate real-time perspective views at operator-selectable times, seasons, and environmental conditions. The system produces video-realistic perspective views at a rendering rate of .5 Mpixels/second and is scalable by a factor of 80.
