The application discloses an infrared image generation method and system based on a physical prior constraint generative adversarial network, relates to the field of infrared image generation, and aims to solve the problems of insufficient physical reality and lack of representation ability of infrared radiation characteristics of the existing infrared image generation method. The application first designs a physical prior knowledge learning network, which is used to learn the prior representation related to the infrared radiation characteristics from the infrared image, and realizes the prediction of the infrared radiation related parameters through a deep learning network. Secondly, a generative adversarial network based on the physical prior constraint is designed based on the proposed physical prior knowledge learning network, the physical prior features are introduced into the image generation process, and the learning ability of the generator to the overall distribution of the infrared radiation and the representation ability of the generator to the infrared radiation characteristics are enhanced. The method breaks through the limitation that the traditional generator only relies on shallow texture mapping. The application is suitable for the fields of visible light to infrared image generation, infrared vision algorithm research and development.

This invention relates to the technical field of infrared imaging, specifically to an automatic imaging control method and system for infrared imaging to combat stray light. The method includes: acquiring image data and corresponding stray light data; determining the stray light imaging influence degree based on device temperature time-series data and light intensity time-series data; correcting the stray light imaging influence degree based on dust particle concentration data to obtain a strong stray light tendency coefficient; the strong stray light tendency coefficient is used to characterize the comprehensive probability of strong stray light interference in the infrared image; determining the comprehensive stray light resistance stability based on the texture difference of the image data and the radiometric stability value corresponding to the infrared image; determining the stray light suppression urgency based on the comprehensive stray light resistance stability and the strong stray light tendency coefficient; and determining the target imaging control mode based on the stray light suppression urgency and a preset threshold, so that the infrared imager performs adaptive imaging control according to the target imaging control mode. This invention can improve the accuracy of stray light imaging control during infrared imaging.
