Implementation of infrared scene simulation based on programmable GPU

Considering the unsatisfied simulation details, low real-time quality and other technical difficulties of previous infrared scene simulation methods, a new implementation method of infrared physical model was proposed. In the method proposed, objects' physical information is bound to the vertices of their geometry model, which improves the description details of infrared scene. By distributing physical model's computation load between CPU and GPU, the new method makes full use of GPU's powerful computation ability, which effectively improves the real-time quality of infrared scene generation. Besides that, the add methods of several typical detector effects were also discussed. Finally, simulation images were used to illustrate the effectiveness of the proposed method, and the advantages and disadvantages of the proposed method were also analyzed.
