Massage chair electric telescopic leg-beautifying foot bottom position detection method

The invention discloses a massage chair electric telescopic leg-beautifying foot bottom position detection method which comprises the following steps: opening foot bottom rollers, then controlling a leg-beautifying lower section foot bottom to stretch out, and judging whether the stretching out is longest or not in real time; after the beautiful leg extends to the longest length, calculating the average current value of a foot sole roller through a real-time sliding window, and collecting the average current value for about 2 seconds; after the average current value of the sliding window is collected, the average current value obtained through calculation is stored, the leg beautifying device is controlled to retract, and the foot sole detection process is started; in the retraction process, foot sole roller current differential modulation is carried out, and a differentiator is used for carrying out differential on sampling current to obtain the change rate of the current; detection of the foot bottom positi
