Description

Computer-determined recording media recording a hairstyle simulation system, a simulation method, and a program for realizing the simulation method

The present invention relates to a computer-readable recording medium that records a hairstyle simulation system, a method, and a program for realizing the method, and more particularly, according to a length and an operation angle of a hair input based on a plurality of head points. By reproducing a specific hairstyle to the actual head image of the client, there is no big difference in the simulated hairstyle and the hairstyle after the actual procedure, thereby realizing a hairstyle simulation system, method and method for maximizing customer satisfaction. A computer readable recording medium having recorded thereon a program.

In general, a customer explains a desired hair style to a hair designer in a word or presents a photo, etc. The hairstyle after the procedure is often not reproduced in the desired hair style. This may be a hair designer's skill difference, but because the shape of the head is different for each customer, even the same hairstyle is reproduced differently according to the head. If the hairstyle differs from the client's expectations after the procedure, the client will be dissatisfied and lose confidence in the hair designer.

In order to minimize this problem, various patents have been disclosed for a hairstyle simulation apparatus or method. Korean Patent Laid-Open Publication No. 2003-0026935 discloses an image processing apparatus, an input / output apparatus, a graphics system, a display apparatus, a head image development information storage apparatus, and a hair.

However, according to the registered patent, the cut is made based on the customer's image, but the cut is performed on a fairly vague and subjective basis called Yin-Yang Design Cut, and only the length of the hair is cut in consideration of the volume. And the concept of the angle of operation in cutting is not disclosed at all. Therefore, even with this method, it is difficult to cut hair by accurately reflecting the actual head shape of the customer, and there is a problem in that a cutting simulation procedure is very complicated.

Therefore, it is possible to simply simulate a variety of hairstyles based on the actual head shape of the customer, but the simulation system and method for demonstrating a hairstyle that does not differ greatly from the hairstyle after the procedure without relying on the hair designer's skill. This is still required.

The input device 110 refers to a device such as a keyboard, a mouse, a touch pad, and the like, and a user may input necessary data by manipulating it. In the case of the present invention, the user may input the front picture, the side picture and the like of the customer by using the input device 110. The front photograph or side photograph of the customer to be input is preferably a photograph in which the head is turned over with a hair band and the head is tied together so that the head of the customer is easily revealed, or the photograph is in a state where a head cap is worn.

The output device 120 refers to a display device such as a monitor, a printer, and the like, and outputs a result value processed by the processing device 140 or the contents of the storage device 130. In the case of the present invention, the output device 120 outputs an image stored in the DB or the hairstyle DB 132, an image of a front photograph, a side photograph, etc. of the customer even if the hair is drawn.

The storage device 130 may include a main memory device and an auxiliary storage device. The storage device 130 may include a DB 131 and a hairstyle DB 132 even when hair is provided, and customer information may be stored. Even with the hair, the DB 131 or the hairstyle DB 132 may be provided separately from the storage device.

Hair diagrams DB 131 according to an embodiment of the present invention stores hair diagram information for a particular hair style of a model having an ideal head form, such as a mannequin head shape. The hair diagram may be a flat or three-dimensional hair diagram, and the flat hair diagram may be useful not only for education but also when providing advice on a client's hair style. It can be usefully used.

Hair diagrams stored in the DB 131 may vary depending on the length and the treatment angle of the hair on the basis of a plurality of head points to be a reference when cutting.

In general, the basic hairstyle is classified into about 12 kinds, the hair diagram DB (131) may include a hair diagram according to a specific hair length and angle for each of these hairstyles, wherein the length of the hair is a specific head In the units such as 10 cm, 20 cm, 30 cm, etc. based on the point, the operation angle may be classified into units such as 15 °, 45 °, 90 °, 120 °, and the like.

Here, the 'operation angle' refers to the angle formed by the tangent and the hair at one point of the head surface when lifting to cut the hair as previously defined. The treatment angle refers to the volume, three-dimensional, weight, etc. of the hairstyle. It is related. Such an angle is a very important factor in hair design, and must be considered in performing hair simulation to produce an accurate hairstyle.

In order to help understand the hair diagrams will be described in more detail with reference to FIGS.

FIG. 2 is an example of a hair diagram stored in a DB for hair diagrams, and will be described with reference to the drawings shown as lines only for convenience of description. FIG. 2A is a side hair diagram, (B) is a front hair diagram, and (C) is a flat (viewed from above) hair diagram. It is preferable that even the hair diagram DB 131 is essentially included in the side hair diagram.

In FIG. 2, 'a', 'b', and 'c' each represent hair lengths, and are hair diagrams in which the lengths of the hairs are the same from the plurality of head points, and the cutting angle from each head point is 90 degrees. It can be seen that the same as °.

3 (A) is another exemplary hair diagram with hair unfolded with respect to the head surface, and 3 (B) is a hair diagram showing the cut condition in units of hair panels cut at 0 ° for the same hair length This is a diagram of hair when the hair panels are cut with increasing angles by 15 ° one by one. Hair style produced based on such a hair diagram is shown in FIG. 3 (C).

The mood of the hairstyle depends not only on the overall length of the hair, but also on the volume of the hair. As already explained, the volume of the hair is especially related to the angle of operation. For example, if the lengths of the hair tips are the same with respect to a specific head point, the smaller the angle of operation, the shorter the actual length of the hair located below the head point in the hair panel and the actual length of the hair located above the head. The longer the angle, the opposite is the case.

As the length of the hairs in the same hair panel is different according to the treatment angle as described above, a layer is formed. Thus, the treatment angle is a factor that determines the volume of the hairstyle.

FIG. 4 is a photograph for explaining that the final hairstyle may be different when the treatment angle is different for the same or similar hair length, and 4 (A) shows the angle of treatment based on a specific head point (back point). 15 °, 4 (B) is the case of 45 °. If the treatment angle is 15 °, the hair ends are hardly formed. Therefore, a short haircut is produced. If the treatment angle is increased to 45 °, the hair ends form a layer. Directed.

The hair diagram DB (131) may store not only the planar hair diagram but also information on the three-dimensional hair diagram as shown in FIG. 5 (A), and the partial hair diagram as shown in FIG. 5 (B). Information about the diagram may also be stored. FIG. 5C is a hairstyle produced based on FIGS. 5A and 5B, which may be stored in the hairstyle DB 132.

Preferably, the hair diagram DB 131 may include a hair diagram according to the hair treatment procedure sequence for a particular hair style, as shown in Figure 6, the hair diagram according to the procedure procedure is output device ( If the output through the sequence in succession through 120), the hair designer will be able to perform the procedure more easily with reference to this.

Meanwhile, the hair diagram DB DB 131 may store a hair diagram for a model having an ideal head shape, and various hair diagrams formed based on the head of the customer depending on the length and the angle of treatment of the hair. It can be the basis for your hair simulation.

In the hairstyle DB 132, various hairstyle images corresponding to various hair diagrams stored in the hair diagram DB 131 are stored. That is, a particular hairstyle is stored to match various hair diagrams formed according to the length and the treatment angle of the hair based on the specific head point. For example, the hairstyle DB 132 stores a hairstyle formed based on a specific hair diagram as illustrated in FIGS. 3 (C), 4 (A), and 4 (B). The hairstyle DB 132 includes information about the hairstyle of the customer as well as the model.

Hair diagrams and hairstyles for the ideal model stored in the hair diagram DB (131) and hairstyle DB (132) can be used as a reference when creating the customer's hair diagram or hairstyle, which will be described below. The hair diagram will be described in more detail in the generator 163 and the hairstyle generator 164. In addition, the information about the model stored in the hair diagram DB 131 and the hairstyle DB 132 may be useful when comparing how the head shape of the customer is different from the ideal head shape in the future.

The processing unit 140 includes a central processing unit (CPU), performs a function of executing a program, processing data, and controlling each device. In particular, the processing device 140 executes a hairstyle simulation program according to the present invention and performs a function of processing data, and a photograph or a flat head image of a customer input through the input device 110 or the imaging device 150. The generation unit 161, the hair diagram generation unit 163, and the hairstyle generation unit 164 may serve to image-process the image generated.

The imaging device 150 is a device for photographing the front, side, etc. of the customer, the customer's picture taken through the imaging device 150 may be image processed through the processing device 140 as described above, It may be provided separately from the input device 110.

The flat head image generating unit 161 according to an embodiment of the present invention generates a flat head image by using the front and side pictures of the customer input through the input device 110 or the imaging device 150. . The reason for generating the flat head image as described above is to accurately identify the shape of the head of the customer and accurately determine a plurality of head points as a reference for cutting to simulate a specific hairstyle suitable for the shape of the head of the customer.

In order to generate a flat head image, it is desirable to receive at least the front and side photographs of the customer. It is preferable that it is a photograph.

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

First, a method of generating a 2D flat head image by the flat head image generator 161 will be described. The method of generating the flat head image may be various. For convenience of description, the method will be exemplarily described with reference to FIG. 7. FIG. 7 (A) is a frontal flathead image generated by the flat head image generator based on a front photograph of a customer, and FIG. 7 (B) is a side flathead image generated by a flathead image generator based on a customer's side photo. to be.

Referring to FIG. 7A, the flat head image generating unit 161 generates the flat head image by forming the inner hairline 61 and the outer hairline 62. Specifically, the hairline image is connected by connecting the hair lines that are the boundary between the face and the head on the basis of the front photograph of the customer, thereby forming a smooth inner hairline 61 and forming the outer hairline 62 along the outside of the head. Can be generated. In this case, the outer hairline 62 may be formed by smoothly connecting the most protruding portion of the upper portion and the most protruding portion to the left and right along the head contour.

In addition, referring to Figure 7 (B), the flat head image generating unit 161 is the inner hairline (left and lower hairline) 63 and the outer hairline (right hairline) based on the portion of the customer's hair is formed. The flat head image can be generated by forming a) 65. Specifically, the inner hairline 63 is formed by smoothly connecting the hair lines formed along the face, the ear and the neck based on the photograph of the side of the customer, and the most protruding part and the most protruding upward from the head part. The line connecting the parts may be connected to both ends of the inner hairline along the head outline of the picture to form the outer hairline 65 to generate a side flat head image.

However, since the flat head image generating unit 161 only needs to generate a flat head image capable of accurately reflecting the head of the customer based on the picture of the customer, the present invention provides a specific method of generating the flat head image. The scope of rights is not limited.

The short hair image of the customer generated by the short hair image generating unit 161 is stored in the storage device 130 or a separate DB, and may be output through the output device 120 when an output request is made. This haircut image may be used as a basis for a hairstyle simulation when a customer visits a beauty salon in order to produce a new hairstyle.

The flat head image generating unit 161 generates a front flat head image based on the front picture of the customer and a flat head image based on the side picture of the customer. You can also create images of flat heads in various directions, such as head images.

For example, a method of generating a backside flat head image may be described with reference to FIGS. 8A to 8. This will be described with reference to 8C. FIG. 8A is a front flat head image, FIG. 8B is a side flat head image, and FIG. 8C is a back flat head image. For convenience of description, the drawings in the form of heads formed only by lines, not actual photographs of customers.

In order to generate the backside flat head image, first, as shown in Figs. 8A and 8B, a rectangular frame capable of determining the size of two images is formed.

The rectangular frame has a horizontal line (a, a ') passing through the most protruding point (TP) in the front view and the most protruding point in the lower jaw, and a vertical line passing through the most protruding point (TSP) in the two heads, respectively. b, b ').

In the side view, the rectangular frame is a horizontal line (c, c ') passing through the most protruding point (TP) and the most protruding point at the lower jaw, and the point where the most protruding side and inner hairline and outer hairline meet. It consists of vertical lines (d, d ') which pass through the upper intersection points among the intersection points.

Next, in FIG. 8A and FIG. 8B, a backside head image is generated by using a head image having a rectangular frame. Typically, the head image is symmetrical, and thus, a single backside head image may be generated using a single side head image and a front head image as shown in FIG. 8C. For example, by generating a rear head image corresponding to the front head in a rectangular frame formed based on the front picture, and forming an overall hair line by referring to the inner hair line from the ear to the neck of the inner hair lines of the side pictures. You can create images of the back flat head.

On the other hand, the flat head image generating unit 161 may generate a more accurate flat head image by correcting the outer hairline of the first formed flat head image inwards within about 1 mm. However, the customer's photo wearing a head-adhesive cap or the appearance of a cranial head may not have to undergo this correction step.

Next, the flat head image generating unit 161 may generate a 3D flat head image using the generated 2D flat head image of the customer. Such a 3D image may be generated using a 3D generated CAD program or other 3D generated program.

For example, the front, side, and rear flat head images generated by the flat head image generating unit 161 may be generated as a three-dimensional 3D image by creating a head shape using a 3D generating program such as CAD and rendering.

In addition, it may be generated by a known method of generating a 3D image based on a 2D picture, for example, a method of generating a feature point. In any case, since the 3D image may be generated based on the 2D image, the scope of the present invention is not limited by the 3D conversion method. The generated 3D image may be stored in the storage 130.

The head image point determiner 162 according to an embodiment of the present invention determines a plurality of head image points at a predetermined position of the head image generated by the head image generating unit 161. In some cases, the flat head 2D or 3D image in which the head image point is determined may be output through the output device 120.

The plurality of head points is a point at which the hair designer is a reference for cutting hair, and the final hairstyle may depend on where the point of reference is to be cut when cutting the hair. Therefore, the process of determining a plurality of head points to be a reference point when cutting based on the exact head shape of the customer is a decisive factor that determines the hair style of the customer, it is necessary to accurately determine this.

These head points include center point (CP) (1), top point (TP) (3), golden point (GP) (5), and back point (BP) (7). ), Nape point (NP) (9), nape side point (NSP) (10), side corner point (SCP) (13), side point (SP) (14), center top mediun point (CTMP) (2), top golden medium point (TGMP: top golden medium point) (4), golden back medium point (GBMP: golden back medium point) (6 ), Back nape medium point (BNMP) (8), ear back point (EBP: ear back point) (11), ear point (EP: ear point) (12), front side point (FSP: front side point) 15 and the like.

These head phase points will be described in more detail with reference to FIG. 8.

Referring to FIG. 8A, a center point CP 1, a side point SP 14, and a front side point FSP 15 are positioned on an inner hairline, and a top point is formed on an outer hairline. TP) (3), Top Two-Section Medium Point (TTSMP) (A), Two Section Point (TSP) (B), etc., and Side Corner Point (SCP) (13) at the point where inner and outer hairline meets. It can be seen that is located.

The side corner point (SCP) 13 is a point where the inner and outer hairline meets, and the point where the straight line connecting the side corner point 13 perpendicular to the straight line meets the inner hairline is the center point (CP) ( 1), and the point where it meets the outer hairline corresponds to the top point (TP) (3). The top point 3 corresponds to the crown portion that protrudes most from the head image.

The side point (SP) 14 on the inner hairline is located at a point where a straight line extending horizontally from the eyebrow portion meets the inner hairline, and the front side point (FSP) 15 extends vertically from the eyebrow mount. Located at the point where the straight line meets the inner hairline.

The two section point (TSP) B on the outer hairline is located at the two most protruding points on the left and right sides of the outer hairline, and the top two-section medium point TTSMP A is the point where the a and b lines meet. It is located at the point where the waterline is lowered from the outer hairline to the waterline.
