Moving target detection method in substation intelligent system

The invention discloses a moving target detection method in a substation intelligent system. The moving target detection method comprises the following steps: a step 1: collecting N frames of images in a substation monitoring system, then figuring out an average value of the N frames of images to serve as a background image; a step 2, after obtaining the background image, carrying out differential operation and threshold segmentation on S1 (x, y) and P (x, y) to obtain a binary image B1 (x, y), and if a moving target exists, turning to a step 3; the step 3, carrying out the differential operation and the threshold segmentation on S2 (x, y) and the P (x, y) to obtain a binary image B2 (x, y), if the moving target exists, calculating a centroid point Q11 (x, y) of the moving target in the B1 (x, y), and calculating the centroid point Q21 (x, y) of the moving target in the B2 (x, y); and a step 4, judging the movement direction of the moving target.
