Method and device for removing background of fixed-point monitoring moving target scene

The invention provides a method and device for removing the background of a fixed-point monitoring moving target scene, and the method comprises the steps: obtaining a plurality of monitoring images, and extracting a color feature Ci(x, y) corresponding to each pixel Ii(x, y) of each monitoring image Ii; for each monitoring image Ii, acquiring the angle values (phi(x, y) and theta(x, y)) corresponding to each pixel point Ii(x, y) are obtained, phi(x, y) is an azimuth frame angle of the pixel point Ii(x, y), and theta(x, y) is a pitching frame angle of the pixel point Ii (x, y); for all the monitoring images, calculating the color feature difference between pixel points with the same angle value in two adjacent monitoring images, and if the color feature difference is smaller than a certain preset threshold value, determining that the region corresponding to the pixel point is a background region; and subtracting the background region from the monitoring image. According to the method, background interference
