Method for estimating operating distance of IR imaging system under complex backgrounds

  • For the application limitation of traditional operating distance model under complex backgrounds, the traditional equation was improved by adding the idea of probability distribution. In the new equation, the variables operating distance and background IR radiance were replaced by vectors, whose dimensions could be calculated according to gray distribution of background image. Then, a new model which is valid in various backgrounds was established. In order to calculate the infrared signature of complex background, a new method that gets radiance from image gray value by establishing radiance-gray function was proposed here. The operating distance calculation instance shows that the new model can accurately estimate the operating distance under complex backgrounds.
