Embodiment 1
[0028] Infrared visual simulation system is a kind of hardware-in-the-loop simulation system, which is widely used in the performance appraisal test of military photoelectric reconnaissance equipment, such as testing the target detection, recognition and tracking performance of infrared photoelectric equipment. This kind of hardware-in-the-loop simulation system can complete test experiments under indoor conditions, and has the advantages of low cost and convenient application compared with traditional field experiments. However, the success of this kind of hardware-in-the-loop simulation system application test largely depends on the simulation fidelity of the infrared vision simulation system, that is, the authenticity of the infrared vision simulation system to reproduce the complex real natural environment.
