Embodiment 1

[0049] Such as figure 2 As shown, this embodiment discloses a method for collecting three-dimensional model data of a human face, that is, step S1 includes the following process:

[0050] S1-1, the face to be collected is positioned in the middle of the viewing range of the viewfinder of the 3D scanner, the face is divided into two head portraits, and the two head portraits are respectively displayed on both sides of the boundary line of the viewfinder frame;

[0051] S1-2, measuring the distance between the 3D scanner and the chin of the face;

[0052] S1-3. Correct the position of the face until the turning surface of the chin can be seen in the viewfinder;

[0053] S1-4. Move the 3D scanner, take photos from different directions, and generate a pair of captured images corresponding to each direction;

[0054] S1-5. Divide the acquired image into a texture image and a grating image, perform binocular matching according to the grating structured light, and finally complete...

Embodiment 2

[0086] Such as image 3 As shown, this embodiment discloses a method for cutting the original nasal prosthesis with laser equipment, that is, step S6 includes the following process:

[0087] S6-1. Dividing the part of the nasal prosthesis to be removed into at least two parallel processing layers;

[0088] S6-2. Adjust the focal length of the laser to within the range of the processing layer to be removed;

[0089] S6-3. Keeping the focal length unchanged, the laser moves in the current processing layer until all nasal prosthesis materials in the current processing layer are removed;

[0090] S6-4. If the current processing layer is the last layer, end the step; otherwise, adjust the focal length of the laser to the next processing layer; return to step S3.

Embodiment 3

[0092] Such as Figure 4 As shown, the present embodiment discloses a method for rhinoplasty, which includes steps:

[0093] A method for rhinoplasty, including the steps of 3D modeling:

[0094] S1-1, the face to be collected is positioned in the middle of the viewing range of the viewfinder of the 3D scanner, the face is divided into two head portraits, and the two head portraits are respectively displayed on both sides of the boundary line of the viewfinder frame;

[0095] S1-2, measuring the distance between the 3D scanner and the chin of the face;

[0096] S1-3. Correct the position of the face until the turning surface of the chin can be seen in the viewfinder;

[0097] S1-4. Move the 3D scanner, take photos from different directions, and generate a pair of captured images corresponding to each direction;

[0098] S1-5. Divide the acquired image into a texture image and a grating image, perform binocular matching according to the grating structured light, and finally ...

Abstract

The invention discloses a nose humping method. The nose humping method comprises the 3D modeling steps that firstly, three-dimensional model data of the human face are collected; secondly, nose model data are intercepted; thirdly, original nose prosthesis model data are imported; fourthly, a nose prosthesis model pattern and a nose model pattern are overlapped; fifthly, the position of the nose prosthesis model pattern is adjusted, and an expected nose humping effect is achieved; sixthly, the difference set of the overlapped part of the nose prosthesis model pattern and the nose model pattern is intercepted from the nose prosthesis model pattern, a personalized nose prosthesis model is obtained, a virtual prosthesis model is formed, automatic equipment is used for machining an original nose prosthesis according to the prosthesis model data, and finally a personalized nose prosthesis the same as the prosthesis model in shape is formed. By means of the nose humping method, the requirement for the skill of a doctor is lowered, and the operation difficulty is lowered; the machined personalized nose prosthesis can be matched with the expected effect better.

Description

technical field [0001] The invention relates to the technical field of plastic surgery, and more specifically, relates to a method for rhinoplasty. Background technique [0002] Rhinoplasty requires the use of nasal prosthesis. Before the operation, the postoperative effect needs to be simulated by computer. Then the doctor chooses the original nasal prosthesis with the most matching shape according to the effect, and compares the expected postoperative effect with a scalpel. The prosthesis undergoes secondary processing, and finally a personalized nasal prosthesis is obtained. The existing technology requires doctors to have superb three-dimensional conception ability and professional cutting skills, so as to ensure that the processed personalized nasal prosthesis fits on the customer's nose and achieves the expected rhinoplasty effect. Therefore, it is difficult to implement the prior art, and the postoperative effect is not easy to guarantee. Contents of the invention ...
