Description

  The present invention relates to an eyebrow drawing assist tool.

  In order to draw a beautiful and well-balanced eyebrow that matches the face of the patient (a person who draws eyebrows), various eyebrow drawing assist tools have been proposed.

  Among these eyebrow drawing assist tools, an eyebrow template that imitates (models) various eyebrows can be easily used, but is not always sufficient for drawing eyebrows that match the face of the individual to be treated.

On the other hand, eyebrow scales for realizing various beauty theories have been proposed.
For example, in a typical standard eyebrow proportion theory, a well-shaped eyebrow is (1) the eyebrow head starts just above the eye, (2) the eyebrow butt is on the extension line connecting the nose and the eye corner, and (3) Mt. Is preferably at a position 2/3 from the eyebrows. An eyebrow scale for realizing the standard eyebrow proportion theory has been proposed.
Also, as a beauty theory different from the above, for example, the slide member is composed of a gripping member and a slide member that can measure the lateral width of the face by sliding relative to the position of the eyebrows with respect to the entire face. Has proposed an eyebrow scale provided with eyebrow drawing means for drawing a reference line (see Patent Document 1).

However, all of the conventional eyebrow drawing assistance tools are used to draw the eyebrows by using the original eyebrows or at least the traces of the eyebrows as a reference, or determining the positions of the eyebrows head and the eyebrow as a reference.
For this reason, in the case of a patient who does not have eyebrows due to illness or any other reason or has few traces of eyebrows, it is not easy to draw eyebrows suitable for the patient using these conventional eyebrow drawing assist tools. That is, even if the drawn eyebrow shape itself is beautiful, depending on the position of the eyebrow to be drawn, there is a high risk of an unnatural and uncomfortable finish when viewed from the entire face.
In addition, according to the beauty theory adopted in the conventional eyebrow scale, the eyebrow has a more natural finish as the facial contour and the size and balance of each part of the face, such as the eyes, nose, and mouth, vary from person to person. It may not always be sufficient for the practitioner who wants to draw.

Next, a method for producing an eyebrow drawing assistance tool according to the third example of the embodiment of the present invention, which can suitably obtain the eyebrow drawing assistance tool 10 according to the first example of the embodiment of the present invention, This will be described below.
A method for producing an eyebrow drawing assistance tool according to a third example of an embodiment of the present invention includes a step of obtaining a face image data by imaging a face of a patient from two directions using a three-dimensional measuring instrument, Based on the face image data, the eyebrow head is positioned on a virtual curve obtained by smoothly extending the curve of the nasal bone side toward the forehead, and the entire eyebrow including the eyebrow head is located between the eyehole and the eyebrow bow or in the vicinity of the eyebrow bow. The method includes a step of positioning and obtaining three-dimensional image data of a mask in which the entire eyebrows are opened, and a step of taking in the three-dimensional image data using a three-dimensional molding machine to produce a mask.
This will be specifically described below.

As the three-dimensional measuring instrument (3D digitizer), for example, a commercially available apparatus such as NEC DANAE can be used as appropriate.
The face of the person to be treated is imaged from two directions with, for example, two CCD cameras provided in the three-dimensional measuring instrument.
The captured face image data is converted into 3D image data by a personal computer provided in the 3D measuring instrument. That is, for example, in the case of DANAE, the object surface is projected using the triangulation principle based on the contrast of the stripes projected on the surface of the three-dimensional shape by projecting a sine wave stripe pattern with the software for generating a three-dimensional image of a personal computer. A polygon mesh of (face image) is created to obtain 3D image data. At this time, as described above, the eyebrow head is positioned on a virtual curve obtained by smoothly extending the nasal bone side curve toward the forehead, and the entire eyebrow including the eyebrow head is positioned between the eyehole and the eyebrow bow or in the vicinity of the eyebrow bow. Further, the three-dimensional face image data of the mask having the entire eyebrow opened is prepared.

As the three-dimensional molding machine (prototyping system), for example, a commercially available apparatus such as DIMENSION manufactured by Marubeni Information Systems Co., Ltd. can be appropriately used.
In the case of DIMENSION, a model material and a support material made of ABS resin supplied from different cartridges are melted by a material melting heater in the modeling head. Based on the three-dimensional image data captured by the apparatus, an ABS resin layer is formed by injection and solidification on a planar area of, for example, 21 cm × 21 cm while the modeling head moves in the X-axis and Y-axis directions, and moves in the Z-axis direction. For example, by laminating at a pitch of 0.2 mm, for example, a mask shown in FIG. 2 based on the three-dimensional image data is obtained.

  According to the method for producing an eyebrow drawing auxiliary tool according to the third example of the embodiment of the present invention, a precise mask can be obtained easily and quickly.
