Figure 6 is a view showing a method of applying the golden ratio of the side of the head, Figures 6a to 6c is an example of the result of the comparative analysis with the head with the golden ratio is applied to the head type of each age group according to the present invention One drawing.

Looking at the method of manufacturing a head-shaped molding according to the present invention, firstly, the present invention classifies a plurality of three-dimensional head-scan data according to the head type for each age group (S100).

In this case, for example, the three-dimensional head scan data of the 609 women among the size Korea 6th anthropometric data were used as a plurality of three-dimensional head scan data. One of the three-dimensional head scan data of the 609 women was used. The 3D head scan data were classified by age group through -way ANOVA analysis.

In addition, the following three-dimensional head scan data classified for each age group is classified according to the head type for each age group. The following factor analysis and cluster analysis were performed.

As shown in FIG. 2, the three-dimensional head scan data may be composed of data of 45 head scan scan items, and in the present invention, factor analysis of data of the 45 head scan scan items may be performed. ) Was performed for each age group, and cluster analysis using the factors extracted through the factor analysis for each age group was performed to perform classification according to the head type of each age group.

The factor analysis is to identify factors that cannot be measured directly based on a series of measured variables, and to simplify the contents by tying a large number of variables into a few factors. In other words, factor analysis can be used for the following purposes. First, many related variables are grouped into a single factor, so many variables are reduced to a small number of factors. Second, even if not included or included in the factor, it is possible to find a variable of low importance so that unnecessary variables can be removed. Third, related variables are tied together to form factors, and these factors have characteristics that are independent of each other. Fourth, the variables measured to measure one characteristic are grouped into one factor. Fifth, based on factor loadings, variables that can be used for additional analysis such as regression, discriminant analysis, and cluster analysis can be made.

In the present invention, the above-mentioned factor analysis was performed to derive four main factors as shown in the following [Table 1].

Factor 1- Length factor	Head _ Lower jaw vertical length, Head _ Right ear bead vertical length, Head _ Vertical nose length, Crest vertical length, etc.
Factor 2- Head depth factor	Nose chin tip vertical length, nose tip back head horizontal length, chin tip back head horizontal length, nose root back head horizontal length etc.
Factor 3- Width factor	Eye bead horizontal length, nose root back head horizontal length, eye ear bead horizontal length, ear ball lip straight etc.
Factor 4- Face factor	Ear bead thigh length, ear bead length, ear bead sign width etc.

Then, cluster analysis was performed on the three-dimensional head scan data of each age group based on the four main factors derived through the factor analysis.

Cluster analysis classifies subjects with high similarity by measuring similarity of each object, and it is a clear standard for classifying subjects by statistical analysis method that identifies similarity between objects belonging to the same cluster and objects belonging to different clusters. This is a technique used to classify objects with various characteristics into groups in the nonexistent or unknown criteria. Cluster analysis is a multivariate statistical technique that groups similar objects based on the characteristics of an object. Two or more groups are formed by cluster analysis, and each group is called a cluster. The key to cluster analysis is to group objects in clusters as similarly as possible and as differently as possible between clusters.

In the present invention, as a result of performing the cluster analysis on the three-dimensional head scan data of women for each age group, the data were divided into four head types for each age group.

The characteristics of the four head types divided by each age group are shown in FIG. 3. Looking at the characteristics of each of the head types in the 40s age group, in the case of the head type I of the 40s age, The horizontal length of the posterior head protrusion is long, and the two-phase type II has the short horizontal length and the vertical head length of the ear ball. The two-phase type III has the long vertical length, and the two-phase type IV has the long length. It can be seen that the horizontal length of the eye-earrings is long. And, as shown in Figure 3, it can also be seen that the characteristics of each head type for each age group appear different.

In the present invention, the above factor analysis and cluster analysis may be performed through, for example, a statistical package for the social sciences (SPSS) developed for data management and statistical analysis, and artificial intelligence such as machine learning. The technique is also applicable.

In addition, the present invention extracts the scan data of the three-dimensional head image represented for each head type of each age group shown in Figure 3 (S110).

At this time, the extraction may extract, as an example, the scan data of the three-dimensional head image closest to the standard head image among the three-dimensional head image scan data belonging to each head type as the three-dimensional head image scan data represented by the head phase type. . Accordingly, among the three-dimensional head scan data corresponding to each age group, one three-dimensional head scan data having three-dimensional head scan data corresponding to their average and values within a preset allowable difference value range is selected. The scan data may be extracted as a representative three-dimensional head image.

The present invention extracts three-dimensional head images representative of each head type for each age group, and then extracts three-dimensional head images of each head group type for each age group. The three-dimensional representative heads are compared with the three-dimensional heads generated by applying the golden ratio of Fibonacci sequence (S120). In particular, the side shape between the three-dimensional representative head image for each head type for each age group and the three-dimensional head image generated by applying the golden ratio of the Fibonacci sequence (S120).

The Fibonacci sequence, created by Italian mathematician Leonardo Fibonacci, is a sequence that starts with the first and second terms starting with 1, and adds the last two terms to the next term.

This is expressed as an equation.

If you look at the characteristics of this sequence,

The ratio of the first and second term is 1/1 = 1

The ratio of the second and third terms is 1/2 = 0.5

The ratio of the third and fourth terms is 2/3 = 0.667

If you go back to infinity like this, this ratio

To converge.

This value is called the golden ratio (GR).

As a result, the golden ratio can be obtained through the concept of extremes.

Where the inverse of the convergence value 0.61803 is

As a result, there is an exact difference of 1, in which the inverse ratio of each term converges to 1.61803, where the ratio of 1: 0.61803, or 0.61803: 1, becomes the golden ratio.

By using the Fibonacci sequence, it is possible to draw a golden ratio rectangle and a curve. When the length of one side continues to draw a square composed of each term of the Fibonacci sequence, it has a golden ratio having an aspect ratio of 1: 0.61803, or 0.61803: 1. A ratio rectangle is drawn, and a curve having a certain shape is drawn by connecting arcs that fit each square, and the actual ammonite shell curve is formed at the golden ratio as shown above.

The present invention applies the above-described golden ratio of Fibonacci sequence to the generation of the length value for each section necessary to shape the three-dimensional head, thereby generating data for the three-dimensional head having the golden ratio.

When generating the length value for each section of the three-dimensional head image including the three-dimensional head image, it is generated by applying the golden ratio of the Fibonacci sequence as shown in the examples shown in Figs.

In addition, the present invention generates length values for each section of the three-dimensional head by applying the golden ratio of the Fibonacci sequence as shown in FIGS. A comparative analysis is performed on the three-dimensional representative head image and its side shape for each head type.

In this case, the comparative analysis, in accordance with an embodiment of the three-dimensional head image generated by applying the golden ratio of the Fibonacci sequence, the predetermined target items related to the side shape of the three-dimensional head image in advance and 3 for each head type of each age group The values corresponding to the items to be compared may be compared with each other between the dimension representative two phases.

6A to 6C illustrate an example of a result of a comparative analysis for each head type of each age group. The comparison target items shown in FIGS. 6A to 6C include a head circumference, a brow length, and a head length. The head length of the ear beads (ho), the head _ left ear ball point vertical length, the horizontal length of the back of the head of the left eye, and the ear width sign width.

As shown in FIGS. 6A to 6C, the difference values may be derived as a result of the comparative analysis of the values corresponding to each comparison target item.
