Problems solved by technology

Focus on indicators that have little influence on the improvement of "beauty" and change the face / body of the beauty seeker according to these indicators. Even if this change is huge, it will not be able to obtain improved visual "beauty" effects

Embodiment 1

[0101] The virtual facial contour adjustment method provided by the present invention is used to guide a female beauty seeker to perform facial contour measurement before facial contour adjustment.

[0102] First, the stereoscopic image data of the human face is obtained through a stereoscopic image device, including an infrared laser light source capable of generating a structured light field, a CCD camera for obtaining light information, a computer central processing unit, and a liquid crystal display. The infrared laser light source emits a structured light field to the wall in front of it. The CCD camera receives the light information scattered by the wall and transmits the light information to the computer central processing unit. The infrared laser light source emits a structured light field to the direction of the wall. The face is placed in front of the wall, and the CCD camera receives the light information highly modulated by the head and face area, and transmits the ...

Embodiment 2

[0118] Based on the three-dimensional coordinate data of the human head and face area obtained in Example 1, using 3D printing technology, print out the reverse model of the human head and face, and use the reverse model as the functional surface to make a cubic groove that can accommodate the head and face model and open at the upper end. The liquid molding material is poured into the mold, dried at 20°C for about 12 hours, shaped to a water content of 9-11%, and demolded to obtain a 3D structure of the human head and face.

[0119] The preparation method of the molding material is as follows: put 320g of gelatin and 360g of water into a container, heat up to 80°C, stir to melt the gelatin, then put in 56g of beeswax and 120g of glycerin in turn, and stir for 3 hours to obtain a uniformly mixed gelatinous material , put the gel-like molding material in a vacuum drying oven, vacuumize at 60°C for 30 minutes, remove the air bubbles in it, and obtain the molding material that can...

Embodiment 3

[0121] Based on the three-dimensional coordinate data of the human head and face area obtained in Example 1, using 3D printing technology, print out the reverse model of the human head and face, and use the reverse model as the functional surface to make a cubic groove that can accommodate the head and face model and open at the upper end. The liquid molding material is poured into the mold, dried at 20°C for about 12 hours, shaped to a water content of 9-11%, and demolded to obtain a 3D structure of the human head and face.

[0122] The preparation method of the molding material is as follows: put 280g of gelatin and 360g of water into a container, heat up to 80°C, stir to melt the gelatin, then put in 64g of beeswax and 112g of glycerin in sequence, and stir for 3 hours to obtain a uniformly mixed gelatinous material , put the gel-like molding material in a vacuum drying oven, vacuumize at 60°C for 30 minutes, remove the air bubbles in it, and obtain the molding material that...

Abstract

The invention discloses a virtual face contour adjustment method. The method is realized through steps of obtaining human face three-dimensional image data; determining an index with high correlationwith the human face contour; obtaining the result of the high correlation index based on the human face three-dimensional image data; performing virtual adjustment of the facial contour based on the result of the high correlation index; repeating a step 3, and determining whether the aesthetic effect of a three-dimensional image of the facial contour obtained after virtual adjustment meets the requirement or not in combination with visual judgment of a person. The method is advantaged in that a simulation stereo image is matched with the determination of the high correlation index of the humanface contour, a subjective error and the ineffectiveness of the low correlation index determined by the traditional aesthetic standard on improvement of the human face can be effectively improved, virtual face contour adjustment is carried out to facilitate formulation of a highly optimized surgery implementation scheme, and the improvement effect of the face contour is improved.

Description

technical field [0001] The invention belongs to the fields of medical measurement and plastic surgery, and in particular relates to a method for adjusting a virtual facial contour. Background technique [0002] Plastic surgery refers to the process of repairing and reconstructing human tissue, organ deformities and defects, as well as reshaping people's appearance and body beauty. Nowadays, people's pursuit of beauty and the development of plastic surgery technology make more and more people participate in plastic surgery, and the satisfaction requirements for plastic surgery are getting higher and higher. However, medical plastic surgery is different from mechanical manufacturing. It is not a streamlined operation and the specific structure of each person's face and body is different, which makes it impossible to produce standardized surgical standards. In other words, medical plastic surgery relies heavily on the experience of the doctor. The doctor's subjective identifi...
