Abstract

The invention discloses an infrared image generation method and device, and relates to the technical field of atmospheric optics. The infrared image generation method comprises the following steps: acquiring infrared radiation observation statistical data of a cloudy sky and a cloudy-free sky; Generating a two-dimensional gray level image with the cloud sky based on a fractal algorithm; And assigning pixel points in the two-dimensional gray level image of the cloudy sky according to the infrared radiation observation statistical data of the cloudy sky and the cloudy-free sky so as to generatean infrared radiation image of the cloudy sky. Through the above steps, the method can effectively solve the problems that the infrared radiation image with the cloud sky generated according to the theory lacks cloud textures and is greatly different from the real radiation condition.

Description

technical field [0001] The invention relates to the technical field of atmospheric optics, in particular to an infrared image generation method and device. Background technique [0002] Clouds are an important part of the sky background, and its appearance is irregular and random. In infrared remote sensing, cloud radiation is the main source of scattered radiation interference in the sky background, which affects the imaging detection of infrared cameras and brings many difficulties to image processing. [0003] Most existing methods for generating infrared radiation images of cloudy sky are based on theoretical calculations. When generating infrared radiation images of cloudy sky based on theoretical calculations, part of the calculation results are single-point data, which cannot be used as the background field. In addition, when generating cloudy sky infrared radiation images based on theoretical calculations, due to the limitation of input parameters, the calculation ...
