Problems solved by technology

Although the existing methods can simulate the appearance after plastic surgery for local areas of the face, they cannot simulate the results of a single injection of hyaluronic acid during the plastic surgery process, so they do not have a guiding role in how to implement each step in the cosmetic surgery

Embodiment Construction

[0035] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] like figure 1 As shown, a cosmetic method of hyaluronic acid injection in three-dimensional human face virtual plastic surgery, comprising the following steps:

[0037] In step 1, the obtained 3D face model is scanned by a 3D scanner.

[0038] In step 2, the user selects three injection parameters, including injection point, injection radius and injection volume. The user needs to interactively select a vertex M on the 3D face model as the injection point, and input the injection radius R and injection volume V, such as figure 2 shown.

[0039] Step 3, for the injection point and injection radius input by the user in step 2, use breadth-first traversal to find all points on the three-dimensional face whose distance from the injection point is smaller than the injection radius, that is, the injection area, such as image 3 shown. Specific s...

Abstract

The invention discloses a Hyaluronic acid injection beautifying method in a three dimensional face virtual plastic surgery; the method comprises the following steps: 1, using a three dimensional scanner to obtain a three dimensional face model, and enabling a user to select injection parameters that includes an injection point, an injection radius and an injection capacity; 2, using a breadth-first traversal method to find all points in an injection area; 3, using a distance field function to calculate the weight of each point in the injection area; 4, using a dichotomy iterative method to calculate the elevation distance of a summit according to the injection capacity inputted by the user, thus obtaining a deformed three dimensional face model. The method uses the three dimensional modeldeformation technology, can simulate the Hyaluronic acid injection effect on the three dimensional face model gathered by the three dimensional scanner, is simple and easy to use, clear in algorithm,friendly in interface, robust in result, and can be applied in virtual face lifting, computer animation and computer gaming field.

Description

technical field [0001] The invention belongs to the field of computer graphics and image processing, in particular to a hyaluronic acid injection cosmetic method in three-dimensional human face virtual plastic surgery. Background technique [0002] With the improvement of people's living standards, the public's pursuit of their own beauty is getting higher and higher, and more and more people are joining the ranks of plastic surgery. Before performing plastic surgery, the plastic surgeon will design a plastic surgery plan to enrich the forehead, nose, and chin according to the characteristics of the face to be plasticized. These operations require the use of hyaluronic acid injections for treatment, but they cannot simulate the results of hyaluronic acid injections. , so there is a need for a simulated hyaluronic acid injection method for a three-dimensional face model. [0003] Existing method is aimed at the simulated plastic surgery method of forehead, nose, chin, mainly...
