In the last year, several moderately priced real-time image generators offering textured rendering have appeared on the market. These image generators provide an opportunity for more realistic IR image simulation by significantly increasing the level of detail of the simulated image with no degradation in real-time performance. As part of the development of a new imaging IR simulator, the authors have incorporated the texturing feature of their image generator with their thermal model to generate thermally accurate textured IR backgrounds. The textured thermal model uses a two-dimensional Markov process to generate a background temperature fluctuation map; this model has been proposed by several studies of thermal IR terrain measurements. The textured surfaces are processed through the radiance and sensor models to generate the simulated images.
