Tool for measuring area of irregular three-dimensional image of head for hair transplantation

The invention discloses a head irregular three-dimensional image area measuring tool for hair transplantation. Relates to the field of hair transplantation quantity measurement, and comprises a supporting part, a conformal part and a position locking part, the supporting part comprises a telescopic assembly connected with the conformal part and used for adjusting the spatial position of the conformal part and a bottom frame, the conformal part comprises an arc cover and moving columns, and the moving columns are distributed in the arc cover in an arc shape; the moving columns slide in the arc cover in the length direction of the moving columns, position locking parts enabling the positions of the moving columns to be stable are arranged between the moving columns and the arc cover, data of different positions of the head are obtained through the multiple moving columns of the device, a curved surface is established in combination with existing three-dimensional software, and the area of the curved surface is
