Key position identification method and device, foot score editing method and device and dancing machine

The invention relates to a key position identification method and device, a foot score editing method and device, computer equipment and a computer readable storage medium. The key position identification method comprises the steps of: reading a key position pressure value detected by footstep action capturing equipment at a beat point position, determining a predicted key position treaded by a user on the footstep action capturing equipment according to the key position pressure value; acquiring a real-time video image of the user on a stepping key position on the footstep action capturing equipment, and extracting human body skeleton movement data corresponding to the beat point position from the real-time video image; calculating angle parameters of each limb of the user relative to a preset human skeleton basic template according to the human skeleton movement data, and determining a prediction area where the stepping key position of the user on the footstep action capturing equipment is located; and if t
