The research on infrared real-time simulation of sea background has important theoretical significance and application value in the development of modern infrared technology. Combined with the existing computer hardware and software conditions, a variety of optimization techniques are introduced, a real-time infrared background simulation method is proposed, and a real-time infrared background simulation of the sea background is realized. Using 2D FFT technology to calculate the geometric data of the sea surface rapidly, introducing Geomipmap technology to optimize the data of the sea surface geometry model, using GPU to accelerate infrared radiation calculation, pre-generating offline data technology and viewpoint-based rendering technology are proposed to improve the real-time rendering speed. Experimental results show that the speed of infrared sea background generated by this method can be up to 300 frames / s, which meets the requirements of real-time simulation. At the same time, more computational resources are reserved for the simulation of other parts of the simulation system.
