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

Embodiment 1

[0040] see figure 1 A method for previewing facial skin restoration based on a three-dimensional model of a human face is provided, comprising the following steps:

[0041] S1: Perform a three-dimensional scan on the area above the neck of the user to obtain three-dimensional face data, and construct a three-dimensional face model according to the three-dimensional face data, and the three-dimensional face model includes the three-dimensional skin layer area and the hairline layer area of ​​the temporal region;

[0042] S2: Construct superficial temporal artery and vein models in the hairline region of the temporal region, superimpose the superficial temporal artery and vein model with the hairline region of the temporal region, and perform a superimposition of the hairline region of the temporal region Bypassing the superficial temporal artery and vein for anchor point selection;

[0043] S3: Carry out skin laxity classification according to the three-dimensional layer area of...

Embodiment 2

[0054] see figure 2 , providing a facial skin restoration preview system based on a 3D model of a human face, including:

[0055] The data scanning module 1 is used to perform three-dimensional scanning on the area above the neck of the user to obtain three-dimensional face data;

[0056] A model building module 2, configured to construct a three-dimensional face model according to the three-dimensional data of the face, the three-dimensional model of the face including a three-dimensional skin layer region and a temporal region hairline region;

[0057] Vascular model construction module 3, used for superficial temporal artery and vein model construction in the hairline region of the temporal region;

[0058] Superposition module 4, for superimposing the superficial temporal artery and vein model with the hairline region of the temporal region;

[0059] Anchor point selection module 5, used to select anchor points for the hairline region of the temporal region bypassing th...

Embodiment 3

[0069] A computer-readable storage medium is provided, wherein the computer-readable storage medium stores program codes for the facial skin restoration rehearsal method based on the three-dimensional model of the human face, and the program codes include the program codes used to implement Embodiment 1 or any possible possibilities thereof. Instructions for the face skin restoration rehearsal method based on the three-dimensional model of the human face in the implementation manner.

[0070] The computer-readable storage medium may be any available medium that can be accessed by a computer, or a data storage device such as a server, a data center, etc. integrated with one or more available media. The available medium may be a magnetic medium (for example, a floppy disk, a hard disk, or a magnetic tape), an optical medium (for example, DVD), or a semiconductor medium (for example, a solid state disk (SolidStateDisk, SSD)) and the like.

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...
