Facial skin repair rehearsal method and system based on human face three-dimensional model

Abstract

The invention discloses a facial skin repair rehearsal method and system based on a human face three-dimensional model. The method comprises the following steps: performing three-dimensional scanningon an area above the neck of a user to obtain human face three-dimensional data, constructing a human face three-dimensional model according to the human face three-dimensional data, constructing a temporal superficial motion and vein model in a temporal hairline layer area, superposing the temporal superficial motion and vein model with the temporal hairline layer area, and performing anchor point selection on the temporal hairline layer area by bypassing temporal superficial motion and vein; dividing skin relaxation grades according to the skin three-dimensional layer area, and designing a line path on the face three-dimensional model according to the skin relaxation grades; selecting a needle inserting point, a inflection point and a needle withdrawing point on the human face three-dimensional model according to the line walking path, and determining a skin deformation area along the line walking path; and performing skin repair rehearsal on the skin three-dimensional layer area onthe face three-dimensional model according to the skin deformation area. The rehearsal effect of facial skin repair can be obtained, the success probability of facial skin repair is improved, and harmto the human body due to repair failure is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a method and system for rehearsing facial skin restoration based on a three-dimensional model of a human face. Background technique [0002] Heart of beauty in everyone. With the advancement of science and technology and the improvement of people's living standards, plastic surgery is favored by many beauty lovers. [0003] Aging of facial tissues includes bone resorption, loss of tissue volume, loss of skin elasticity and relaxation. This results in aging around the eyes (loose skin around the eyes, tear grooves, bags under the eyes, etc.), downward movement of the zygomatic buccal fat pad in the middle face (flattening of the mid-face, deepening of the nasolabial folds, etc.), sagging and bloated accumulation of soft tissues in the lower face (corner pockets, pouches, etc.) The outline of the mandibular margin is not clear, marionette lines, ma...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many shortcomings in the existing thread embedding lifting techniques: choosing the zygomatic arch ligament as the fixed anchor point will easily cause widening and deformation of the face, ignoring the cutting effect of the thread teeth on the tissue without leaving redundancy, resulting in too short maintenance effect, and ignoring the mechanical balance Abnormal facial expression movements, difficulty and short-term effect maintenance, complex postoperative tissue swelling and long recovery period, etc. The experience is too poor, and the pinholes and walking positions are sunken for a long time, etc.

At this stage, the phenomenon of plastic surgery failure is also emerging in an endless stream
