Infrared image rotation motion blurring recovery method based on thermal diffusion model

The invention discloses an infrared image rotation motion blurring recovery method based on a thermal diffusion model, and belongs to the field of image processing. According to the method, the imaging process of the infrared focal plane detector is described through a thermal equilibrium equation, a thermodynamic system composed of detector pixels and the surrounding environment is constructed, and when no external radiation enters, the thermodynamic system is in a thermal equilibrium state; when external radiation enters, the temperature of the pixel of the detector rises, and finally a new heat balance state is achieved. The pixel temperature rising process is described by a heat balance equation, the heat balance equation is a differential equation, and a heat diffusion model is obtained by solving the differential equation. According to the method, the exponential decay type rotary motion blurring kernel model is constructed based on the thermal diffusion model, the rotary motion blurring kernel model ca
