Hair diagrams can be either planar or cubic hair diagrams, and planar hair diagrams can be useful not only for educational purposes but also for advice on customers' hair styles, and also for hair designers It can be useful.

The degree of the hair diagram stored in the DB 131 may vary according to the length of the hair and the angle of operation based on a plurality of hair-point points serving as a reference at the time of cutting.

In general, the basic hair style is classified into about 12 types. In the hair styling diagram 131, hair diagrams according to specific hair lengths and angles may be included in each of these hair styles. In this case, In terms of points, 10 ㎝, 20 ㎝, 30 ㎝, and so on can be classified into units such as 15 °, 45 °, 90 ° 120 ° and so on.

Herein, the term "treatment angle" refers to the angle formed by the tangential line and the hair at one point of the curved surface when lifted to cut the hair as already defined. The angle of the treatment refers to the volume feeling, . Such an angle is a very important factor in hair design. Therefore, it is necessary to consider the hair simulation in order to produce an accurate hair style.

To facilitate understanding of the diagram, a more detailed description will be given with reference to FIG. 2 to FIG. 5.

FIG. 2 is an illustration of a diagram of a hair diagram stored in the DB, which will be described with reference to the drawings only for the convenience of explanation. Fig. 2 (A) is a side view of the side view, Fig. 2 (B) is a front view of the hair, and Fig. 2 (C) is a plan view of the hair. It is preferable that the DB 131 necessarily includes a side view diagram.

The atmosphere of the hair style depends not only on the length of the whole hair but also on the volume of the hair. As described above, the volume feeling of the hair is particularly related to the treatment angle. For example, if the length to the hair end is the same as the specific hair point, the actual length of the hair located below the hair point in the hair panel becomes shorter as the treatment angle is smaller, and the actual length of the hair located on the upper side The larger the angle of operation, the more the opposite.

In this way, when the length of the hair in the same hair panel is different according to the angle of operation, the layer is finally formed, so that the operation angle is a factor for controlling the volume feeling of the hair style.

FIG. 4 is a photograph for explaining that a final hair style can be changed when the treatment angle is different for the same or similar hair length. In FIG. 4 (A), a treatment angle 15 °, and 4 (B) is a case where the treatment angle is 45 °. When the treatment angle is 15 °, hair layer with short hair is produced because hair layer is hardly formed. On the other hand, when the angle of treatment is increased to 45 °, hair layer is formed at the end of hair, .

A photograph of a customer photographed through the image capturing apparatus 150 can be processed through the processing apparatus 140 as described above, This may be separately provided from the input device 110. [

The head image generation unit 161 according to an embodiment of the present invention generates a head image using the front and side images of the customer inputted through the input device 110 or the image pickup device 150 . The reason for generating the miniature hair image is to simulate a specific hair style suited to the customer's head shape by accurately grasping the customer's head shape and accurately determining a plurality of hair point points as a reference at the time of cutting.

In order to generate the head image, it is preferable to receive at least the front and side photographs of the customer. In addition, it is preferable that the head is bound to the inner hair line, which is the boundary between the face and the head, Is preferable.

The minutia-head image generating unit 161 may generate a 2D minutiae image first based on the input front and side photographs, and then generate a 3D minutiae image that can be rotated as a three-dimensional shape.

First, a method for generating the 2D head image by the head image generation unit 161 will be described. The method of generating the minutiae head image may vary, and will be described by way of example with reference to Fig. 7, which is shown as a line for convenience of explanation. 7 (B) is a side view of a side image of a customer created by the customer's side photograph, and FIG. 7 (B) is a side view of the customer's side to be.

Referring to FIG. 7 (A), the sub head image generation unit 161 generates the sub head image by forming the inner hair line 61 and the outer hair line 62. Specifically, a hair line which is a boundary between a face and a head is connected to form a smooth inner hair line 61 on the basis of a front photograph of a customer, and an outer hair line 62 is formed along an outer periphery of the head, Lt; / RTI > At this time, the outer hair line 62 may be formed by smoothly connecting the most protruding portion of the head portion and the most protruding portion of the head portion along the outline of the head.

7 (B), the minutia hair image generation unit 161 generates the minutia hair image by using the inner hair line (left and lower hair line) 63 and the outer hair line ) 65 in order to generate a sub head image. Specifically, hair lines formed along the face, ear portion, and neck portion are smoothly connected to form an inner hair line 63 based on the side photograph of the customer, and a portion protruding most upward from the head portion, And the outer hairline 65 may be formed by connecting the line connecting the parts to the ends of the inner hairline along the outline of the two-phase image of the photograph, thereby generating a lateral pinhole image.

However, since the minutest image generating unit 161 can generate a minutest image that can accurately reflect the image of the customer based on the photograph of the customer, the minutest The scope of rights of the present invention is not limited.

The customer's thumbnail image generated by the thumbnail image generation unit 161 may be stored in the storage device 130 or a separate DB, and may be output through the output device 120 if an output request is made. These miniature images could be used as a basis for hair style simulation if customers look for hairdressers in the future to create a new hairstyle.

The minutest image generating unit 161 generates a minutest head image based on a customer's front photograph and a side minutest image based on a side photograph of the customer, It is also possible to generate the image of the head of the head in various directions such as the head image.

Illustratively, a method of generating the back side minutiae image will be described with reference to Figs. 8A to 8C. Fig. 8A is a front minutiae head image, Fig. 8B is a side minutiae head image, and Fig. 8C is a back minutia head image. For the sake of convenience of explanation, it is described as a figure of a head shape formed only by a line, not a real photograph of a customer.

In order to generate the back side minutiae image, first, a rectangular frame capable of determining the size of the two sides is formed, as shown in Figs. 8A and 8B.

This rectangle frame has a vertical line passing through the horizontal line a and a 'passing through the uppermost protruding point TP and the most protruding point of the lower jaw from the front photograph, b, b ').

In the side view, the rectangular frame has horizontal lines (c, c ') passing through the uppermost protruding point (TP) and the most protruding point on the lower jaw, and a horizontal line (D, d ') passing through the upper intersection of the intersections.

Next, in FIGs. 8A and 8B, a backside image is generated using a top image formed with a rectangular frame. Since the two-phase image is symmetrical in the left and right direction, it is possible to generate a back-side image of a head-side image having a hairline as shown in FIG. 8 (C) using one side image and a front image. For example, after creating a rear-view image corresponding to the front face in a rectangular frame formed on the basis of a front photograph, an entire hair line is formed by referring to the inner side hair line from the ear portion to the neck portion of the inner side hair line You can create an image of the back side of the head.

Meanwhile, the minutia image generating unit 161 may generate a more accurate minutiae image by correcting the inside hair line of the first formed minutiae image to within about 1 mm inward. However, in the case of a customer photograph wearing a head cap or the like, or in which a head shape is almost visible, this correction step may not be required.

Next, the sub head image generation unit 161 can generate a 3D sub head image using the generated 2D sub head image. Such a 3D image can be generated using a 3D generated CAD program or other 3D generation program.

Illustratively, a stereoscopic 3D image can be generated by creating a two-dimensional image using the 3D generation program such as CAD, and rendering the front, side, and back side images generated by the stereoscopic image generation unit 161, by rendering.

It can also be generated by a known method of generating a 3D image based on a 2D photograph, for example, a method of generating based on a feature point. Since the 3D image can be generated based on the 2D image by any method, the scope of right of the present invention is not limited by this 3D conversion method. The generated 3D image may be stored in the storage device 130.

The head point determining unit 162 according to an embodiment of the present invention determines a plurality of head points at a predetermined position of the head image generated by the head image generating unit 161. In some cases, a minutia 2D or 3D image having the thus determined two-point points can be output through the output device 120. [

The plurality of hair points may be a point at which the hair designer is to be used when cutting hair, and the final hair style may be determined depending on where the point of cutting is to be taken when cutting the hair. Therefore, it is necessary to accurately determine a plurality of hair point points that become the reference point at the time of cutting based on the accurate head shape of the customer, since it is a decisive factor that determines the hair style of the customer.

Hereinafter, a method of simulating a hair style using the hair style system described above will be described with reference to FIG. 10 is a flowchart for explaining a hair style simulation method according to an embodiment of the present invention.

First, after running the hair style simulation software according to the present invention, a front photograph and a side photograph of a customer are input through an input device or an imaging device (S100). As described above, it is desirable that the customer's frontal and lateral photographs are images that reveal the customer's head shape and hairline.

Next, the mini-head image generating unit generates a customer's 2D mini-head image and the 3D mini-head image using the front and side photographs of the customer (S110).

Subsequently, the head point determining unit determines a plurality of head points that serve as a reference in cutting the head image of the customer generated by the head image generating unit (S120).

Next, when the hair length and procedure angle of the current hair style of the customer are inputted (S130), the length of the hair diagram of the model stored in the DB and the corresponding length of the hair corresponding to the procedure angle The hair style diagram is generated on the customer's hair style image with reference to the hair style diagram, and the hair style creation section applies a specific hair style to the customer's hair style image based on the customer's hair style diagram (S140). This particular hairstyle is output through an output device.

In this case, before the customer directly creates a desired hairstyle, it is necessary to check the image of the current hair style of the customer through the output device by inputting the hair length and procedure angle of the current hairstyle of the customer, And the hair style recommendation section may recommend various hair styles suitable for the customer's head shape before and after the hair drawing or after the customer's current hair style creation based on the input photograph of the customer.

After checking the current hairstyle of the customer which is output by the customer, the user can select a desired hairstyle from the recommended hairstyle, or refer to the hair style book to describe the desired hairstyle. The hair length and the procedure angle for the hair style are input (S150).

In step S150, when the hair length and the operation angle are input, the hair diagram generation unit generates a corresponding hair diagram, and the hair style creation unit generates a corresponding hair style on the customer's hair image (S160) Output device.

If the customer is satisfied with the output hair style (S170), if the customer is satisfied, the simulation is terminated after storing the hair diagram and hair style for the inputted hair length and operation angle, and if not satisfied The length of the hair and the operation angle are newly inputted until the customer is satisfied, and the hair diagram and the hair style corresponding thereto are generated. That is, steps S150 and S160 are repeated until the customer is satisfied.

According to the hair style simulation system and method of the present invention described above, it is possible to easily simulate specific hair diagrams and hair styles according to the customer's head even if only the hair length and the operation angle are inputted as numerical values.

Accordingly, the customer can easily select a hairstyle suitable for her, and the difference between the selected hairstyle and the hairstyle after the actual hairstyle can be minimized, thereby improving not only the customer satisfaction but also the reliability of the hair designer. In addition, it is possible to make the hairstyle and hairstyle objectively based on the numerical value, so that the hairstyle can be minimized by changing the hairdresser's ability.
