Infrared simulation and implementation of virtual ocean scene

Research of modeling infrared radiation characteristic of ocean background plays an important role in areas like marine remote sensing, prevention and control of ocean pollution, meteorological observation, and so on. In this paper, we build a three-D ocean surface model based on P-M wave spectrum, then set up the camera projection model. We use LOWTRAN 7 to calculate solar irradiance and sky background radiance, and then use thermal radiation theory to calculate the thermal radiation of the ocean itself and use bidirectional reflectance distribution function to calculate the reflection of the sea to the solar radiation and sky background radiance. Finally, with all the above radiation components considered, we generate the ocean background infrared simulation image.
