Abstract: Noise is the cause of image degradation and video quality decrease, and the simulation of infrared image noise and its impact is the core of establishing image degradation model. Various noise signals in infrared imaging noise analysis, ultimately reflect in the output image of IR camera, become various imaging noises. In this paper, all kinds of primary noise signals in the IR camera imaging process are mapped to the random noise and fixed pattern noise in infrared image, the noise model of infrared image is established, and noise characteristic parameters are extracted from the output video of actual thermal imaging system as the input of infrared image noise simulation system. Simulation experiment result of static image noise in infrared imaging system is close to the actual infrared image noise. The paper has built up a foundation for modeling IR camera imaging degradation.
