Badminton step training detection method and system based on image operation

The invention relates to a badminton step training detection method and system based on image operation, wherein the badminton step training detection method based on the image operation comprises thefollowing steps : acquiring an image of a badminton court through a camera; extracting a running target area from the image of the badminton court, and further acquiring coordinate information of each running target area in the image; acquiring an image for carrying out step training on the badminton court by a player through the camera; extracting pixels of each running target area from the image for step training, subtracting the pixels of each running target area in a current frame from the pixels of each running target area in a previous frame; if the pixel difference value exceeds a given threshold value, adding 1 to the counting of the running target ; finally, the actual counting of each running target area is counted and divided by the accumulated counting of instructions at corresponding points in the ba
