Abstract

The invention relates to the field of computer infrared imaging simulation, in particular to a real-time infrared dynamic scene simulation method for multiple objects in a sea and sky background. The method comprises the steps of infrared modeling, scene construction, infrared calculation, infrared atmospheric transmission, real-time infrared scene generation, and rendering to generate a real-time infrared scene simulation image. Compared with the general infrared scene simulation, the method has the advantages that the simulation scene content is rich, one scene includes a sea surface, a sky, ships and multiple types of airplanes, the method can still meet real-time requirements in the complicated scene, the dynamic scene can be constructed in real time according to current data, and the infrared scene image is simulated and generated in real time.

Description
