Abstract:Infrared imaging technology is widely used in the field of aerospace. However, because image acquisition requires a lot of manpower and material resources, and meteorological conditions often cannot meet the needs of experiments, infrared simulation technology has become an economical and effective supplement. The infrared simulation images generated by different simulation platforms are quite different, which is an urgent requirement for evaluating the fidelity of infrared simulation systems. Based on the analysis of the key factors affecting the infrared simulation technology, this paper compares the simulation image with the real image from the Angle of the infrared radiation distribution and the similarity and fidelity of the image. The infrared radiation statistical parameters and multiple quality evaluation factors are selected to extract and compare the image features. Finally, the comprehensive quality assessment results of infrared simulation images are obtained, and the experimental results verify the effectiveness of the method.
