Abstract In order to improve the visibility of nighttime thermal infrared images, a simulation method with daytime color images was proposed.
As a simulation method consisting of two steps, the daytime thermal infrared image was simulated by learning the unpaired nighttime
thermal infrared image and daytime thermal infrared image, then the result was translated into a daytime color image. A temperature
change regression equation was constructed and applied to reflect the systematic characteristics of temperature changes in daytime and
nighttime images, and day and night simulation and colorization were trained and modeled by CycleGAN. For the experimental area,
100 images were captured and used for training. As a result, the simulation showed an average SSIM of 0.2449 and a PSNR of 51.2254.
It was confirmed that the method could simulate complex and detailed features such as vegetation.
