Airport lamp detection method and system based on image processing

The invention relates to the technical field of foreground and background segmentation of images, in particular to an airport lamp detection method and system based on image processing, and the method comprises the steps: obtaining each lamplight irradiation region in an airport image, and determining each arc line in the lamplight irradiation region; dividing the pixel points on the arc line into a first type of pixel points and a second type of pixel points, and determining the probability that the second type of pixel points are shadow pixel points; determining the gray correction degree of the second type of pixel points according to the probability that the second type of pixel points are shadow pixel points and the gray value of each first type of pixel points; according to the gray correction degree of the second type of pixel points and the gray values of the first type of pixel points and the second type of pixel points, the abnormal degree of the lamp is determined, and then whether the lamp in each
