Infrared emissivity image simulation method and device, storage medium and equipment

The invention provides an infrared emissivity image simulation method and device, a storage medium and equipment, and the method comprises the steps: obtaining an original visible light image, carrying out the ground object classification processing of the visible light image, and obtaining a target region corresponding to at least one target type in the visible light image; calculating a gray level histogram of a target area corresponding to each target category, and determining gray level extreme value data of the gray level histogram; determining the emissivity extreme value data of the target category; and carrying out matching conversion on the gray maximum and minimum data and the emissivity maximum and minimum data to calculate the emissivity data of the target area corresponding to the whole area so as to obtain an infrared emissivity image. According to the invention, the optical image is adopted as a basic data source, and prior data such as material attributes are combined to realize abundant simul
