Abstract

The invention provides an infrared detector simulation image generation method and device, and the method comprises the steps: carrying out the processing of the signal transmission characteristics of an optical system for an original scenery infrared radiation energy image, and obtaining a series of scenery infrared radiation energy images; fourier transform is carried out on the last scenery infrared radiation energy image in the series, the last scenery infrared radiation energy image is converted into a frequency spectrum image, and centralization processing is carried out on the frequency spectrum image; calculating a plurality of transfer functions corresponding to each pixel point in the frequency spectrum image after the centralization processing, multiplying the plurality of transfer functions, multiplying the obtained result by a two-dimensional matrix of the frequency spectrum image after the centralization processing, executing decentralization processing, and performing Fourier inversion on the decentralization processing result to obtain a voltage signal; and carrying out gray scale quantization on the voltage signal, adding a noise effect, and finally generating an infrared detector simulation image. According to the scheme of the invention, the imaging process of the infrared detector can be truly presented.

Description

technical field [0001] The invention relates to the field of infrared imaging simulation, in particular to a method and device for generating an infrared detector simulation image. Background technique [0002] Due to the complex structure of the infrared detector system used in the military and space fields, and the changing environmental conditions of its field test, if the detector system is not fully mathematically modeled and analyzed during the development period and before it is put into production, and the computer Simulation may lead to many detours in development, production, testing, etc., resulting in a lot of waste and losses, which not only increases costs, but also reduces efficiency. [0003] The imaging simulation of the infrared detector system can better simulate the entire imaging process of the infrared detector, help us better understand the influence of various limited factors on the system performance, and provide considerations when designing the par...
