Description

Hair care system based on hair cuticle monitoring}

The present invention obtains a cuticle image on the hair surface by magnifying the human hair surface and displays the result of the cuticle image as an objective numerical value, so that each individual can easily check the health status of the hair. It's about technology.

More specifically, in the present invention, when a single hair located in the hair enlargement fixing unit is photographed through a smartphone camera unit for the hair in a state in which it is enlarged through the lens member, a dedicated app installed in the smartphone is applied to the hair. After obtaining a cuticle image corresponding to the cuticle provided on the surface, the user can easily know the health state of the cuticle corresponding to the numerical value by digitizing the shape indicated by the outline of each cuticle from the cuticle image.

In particular, the so-called Root Mean Square (RMS) technique is used to identify the difference between the shape of the cuticle of damaged hair (eg, a bumpy and squashed shape) compared to the shape of the cuticle of healthy hair (eg, a flat square). Accordingly, even if the shape of the cuticle is slightly damaged, it relates to a technology that allows the damaged result to be clearly revealed.

Human hair can be protected by a plurality of cuticles provided on its surface, and the plurality of cuticles are interconnected to form a layer, and the health status of the hair can be assessed according to the shape of the cuticle.

[FIG. 1] is an enlarged view of a plurality of hairs in different states. The cuticle layer formed on the surface of the hair has a different appearance depending on the health condition of the hair, as shown in FIG. 1 .

For example, in normal hair, each cuticle of the cuticle layer shows a standardized shape (eg, a flat square) as shown in the first picture of [Fig. 1], but damaged hair shows the cuticle layer of the cuticle layer as shown in the second picture of [Fig. 1]. Each cuticle exhibits a deformed shape (eg, a bumpy and squashed shape) from a standard shape.

And, in severely damaged hair, the area of each cuticle existing in the cuticle layer is greatly reduced as shown in the third picture of [Fig. 1], and in very severely damaged hair, the cuticle layer almost exists as shown in the fourth picture of [Fig. 1] won't do it

Here, even if the surface state of the hair is variously changed as in [Fig. 1] above, although an expert (eg, a doctor) can diagnose the current state of the hair, an individual can objectively judge his/her own hair. It is difficult to get down.

On the other hand, as in [Fig. 1], if the health status of hair can be assessed according to an objective evaluation through the shape of a number of cuticles formed on the surface of the hair, the user can take care of his/her own hair by accurately photographing the hair surface of the human body. can be easily continued.

Accordingly, by objectively quantifying the state of the cuticle after checking the state of the hair cuticle by magnifying the surface of the hair, it helps the user to objectively and conveniently judge the health of the hair, thereby solving the problems of the prior art as described above. Technology implementation is required.

2 and 3 , the hair care system through hair cuticle monitoring according to the present invention may include a hair enlargement fixing unit 100 and a cuticle measuring unit 200 .

Here, the hair enlargement fixing unit 100 mechanically fixes individual hairs inside itself and enlarges the hair at a high magnification in the fixed state.

And, the cuticle measuring unit 200 is a dedicated app installed on the smart device 10, and controls the operation of the camera unit 11 of the smart device 10, digitized data from the cuticle image taken by the camera unit 11 create

Specifically, referring to [FIG. 2] and [FIG. 3], the hair expansion fixing unit so that the through hole 111 of the hair expansion fixing unit 100 into which the hair is inserted is located in the camera unit 11 of the smart device 10. (100) is placed on top of the smart device (10).

Then, as the camera unit 11 is operated through the shooting control module 210 of the smart device 10 in a state in which the dedicated app of the smart device 10 is running, the hair enlargement fixing unit through the through hole 111 At (100), the enlarged hair is photographed at a high magnification.

At this time, looking at the hair enlargement fixing unit 100 , after the lens member 120 is seated on the upper surface of the base 110 in a state in which each hair is mounted along the mounting groove 121 of the lens member 120 , Sequentially, the cover member 130 is seated on the upper surfaces of the base 110 and the lens member 120 .

In this way, when the hair enlargement fixing unit 100 is superimposed on the camera unit 11 of the smart device 10 in a state where a single hair is mounted on the inside of the hair enlargement fixing unit 100, the camera unit 11 The individual hair seen as the through hole 111 when viewed from the viewpoint is mounted in the mounting groove 122 and enlarged by the lens 121 at a high magnification.

The camera unit 11 takes a picture of the hair in a state of being enlarged at such a high magnification.

In addition, in order to represent the state in which the hair seen through the through hole 111 of the base 110 is enlarged at a high magnification, light must enter the lens 121 of the lens member 120 and penetrate based on the lens 121 . Light from the outside may enter the lens 121 through the light-transmitting hole 131 of the cover member 130 opposite to the ball 111 .

To this end, the hair enlargement fixing unit 100 according to the present invention may include a base 110 , a lens member 120 , and a cover member 130 with reference to FIGS. 2 and 3 . The cuticle measuring unit 200 according to the present invention includes a photographing control module 210, a display control module 220, a cuticle analysis module 230, a numerical calculation module 240, a result output module ( 250) may be provided.

First, the base 110 is in the form of a flat plate as in [Figs. 2] and [Fig. 3], so that human hair can be mounted on its upper surface, and the lens member 120 is fixed in the central part. A cut-out groove corresponding to the outer shape of the lens member 120 may be formed.

In addition, the base 110 may have a through hole 111 penetrating in the vertical direction in the cut-out groove portion in which the lens member 120 is seated in the central portion as shown in FIG. 3 . As a result, the lens 121 and the through hole 111 of the lens member 120 may be arranged to be positioned on a straight line in the vertical direction.

At this time, if the camera unit 11 of the smart device 10 is disposed in the lower portion of the through hole 111 , the camera unit 11 is mounted on the lens member 120 through the through hole 111 at the point of view of the camera unit 11 . The hair will look enlarged at high magnification.

The lens member 120 is seated on the upper surface of the base 110 corresponding to the upper portion of the through hole 111 as shown in FIGS. 2 and 3 . When the hair is seated in the mounting groove 122 formed on the upper surface of the lens member 120 , the lens 121 provided at the position through which the mounting groove 122 passes enlarges the hair at a high magnification.

As a result, when looking upward from the lower part of the through hole 111 , the individual hairs mounted along the longitudinal direction of the mounting groove 122 formed on the upper part of the lens 121 will be enlarged at a high magnification.

The cover member 130 is configured to cover the upper surface of the base 110 as shown in FIGS. 2 and 3 to fix the lens member 120 to the base 110 .

In addition, a light transmitting hole 131 penetrating in the vertical direction may be provided in the central portion of the cover member 130 . The light-transmitting hole 131 is preferably positioned on a vertical line formed by the through-hole 111 and the lens 121 .

The shooting control module 210 is a configuration of the cuticle measuring unit 200 installed as a dedicated app of the smart device 10, and a smart device ( 10) may be configured to control the shooting operation for the camera unit 11 while the dedicated app is running.

For example, when the user's touch event for the 'photographic touch unit' activated on the screen on the dedicated app occurs while the dedicated app installed in the smart device 10 is running, the photographing control module 210 sends the photographing control module 210 to the smart device 10 . Upon request, the photographing operation of the camera unit 11 may be indirectly controlled.

The display control module 220 is a configuration of the cuticle measuring unit 200 installed as a dedicated app of the smart device 10. As shown in FIG. 2, the camera unit is controlled by the shooting control module 210 during the execution of the dedicated app. (11) controls to display the cuticle image taken on the screen of the smart device (10).

The cuticle analysis module 230 is a configuration of the cuticle measuring unit 200 installed as a dedicated app of the smart device 10. During the execution of the dedicated app, the smart device is controlled by the display control module 220 as in [Fig. 2]. 10 is configured to analyze the cuticle image displayed on the screen.

Numerical calculation module 240 is a configuration of the cuticle measuring unit 200 installed as a dedicated app of the smart device 10. As in [Fig. 2], the cuticle analysis module 230 for the cuticle image during the execution of the dedicated app. The analyzed data can be quantified.

Then, the result output module 250 is configured to inform the surface state of the hair based on the data digitized by the numerical calculation module 240 during the execution of the dedicated app as in [Fig. 2].

For example, the numerical calculation module 240 digitizes the cuticle analysis module 230 on the basis of the analysis result performed on the cuticle image, and the result output module 250 responds to the digitization and performs smart operation of the dedicated app. A process of informing the screen of the device 10 of the surface state (eg, normal/damaged) of the corresponding hair is as follows.

First, the cuticle analysis module 230 performs shape analysis on a plurality of individual 'cuticles' from the 'cuticle image'. As a result of the shape analysis for individual cuticles, the cuticle analysis module 230 detects each 'analysis outline' (L1 in [FIG. 5]). In addition, the cuticle analysis module 230 may detect a 'virtual outline' (V1 of [FIG. 5]) for each 'cuticle' based on each 'analysis outline'.

Subsequently, the numerical operation module 240 may measure a so-called root mean square (RMS) of the 'virtual outline' based on the 'analysis outline' and the 'virtual outline'.

That is, the numerical operation module 240 sets a plurality of 'sampling' positions from the error between the 'virtual outline' and the 'analysis outline', and the 'analysis outline' is recessed from the 'virtual outline' at each 'sampling' position. It can be quantified by deriving a plurality of negative deviation values and a plurality of positive deviation values in the form of protruding 'analysis outlines' from 'virtual outlines'.

And, the result output module 250 determines whether the surface state of the hair is healthy or damaged, and if it is damaged, it is severe based on the numerical result values based on the plurality of negative deviation values and the plurality of positive deviation values. It can be displayed on the screen of the smart device 10 .

[FIG. 4] is an exemplary view in which one person's hair is enlarged over time through the hair care system according to the present invention, and [FIG. 5] is an analysis of hair cuticles detected by the cuticle analysis module according to the present invention 1 is an exemplary diagram illustrating an outline and a virtual outline, and FIG. 6 is an exemplary diagram illustrating a process in which the numerical calculation module according to the present invention samples from the profile of the analysis outline in order to measure the RMS of the virtual outline.

First, as in (a) to (d) of [Fig. 4], the hair for one person is photographed over time and then the cuticle on the surface of the hair is analyzed so that the condition of the hair is good over time It can be confirmed through the system of the present invention whether it is changed or damaged.

Here, as in (a) to (d) of [Fig. 4], it will be possible to know how the corresponding hair reacts when external factors such as hair treatment or dyeing are changed during the passage of time.

However, by analyzing the cuticle displayed on the surface of the hair at a certain point in time, whether the hair is in a good state or a damaged state can also be displayed as an objective numerical value.

To this end, what shape the hair surface cuticles are in good or healthy shape (e.g., flat square 'Type 1') and what shape (e.g. 'type 2', which are bumpy and squashed) are damaged. We need a definition of cognition.

As a result, the analysis outline (L1) and the virtual outline (V1) are detected from the cuticle image as in [Fig. 5] and [Fig. 6], and based on the detected analysis outline (L1) and the virtual outline (V1), the so-called By applying the 'RMS technique', it is possible to clearly distinguish an error between the analysis outline L1 and the virtual outline V1.

For example, as in [Fig. 5], after the cuticle analysis module 230 detects the analysis outline L1 from the cuticle image, a virtual outline V1 for each cuticle is calculated based on the detected analysis outline L1. can be detected.

Subsequently, the numerical operation module 240 may set a plurality of 'sampling' positions on [Fig. 6] from the error between the analysis outline L1 and the virtual outline L1 on [Fig. 5], respectively.

In addition, the numerical operation module 240 includes a plurality of negative deviation values in the form in which the analysis outline L1 is recessed from the virtual outline V1 and the virtual outline V1 at each 'sampling' position as in [Fig. 5]. It can be quantified by deriving a plurality of positive deviation values in the form in which the analysis outline L1 protrudes from the .

Here, the result output module 250 determines whether the surface condition of the hair is good or damaged based on the result values digitized based on the plurality of negative deviation values and the plurality of positive deviation values derived by the numerical calculation module 240 . is displayed on the screen of the smart device 10 to inform.

On the other hand, the process of applying the so-called 'RMS technique' by the numerical calculation module 240 based on the analysis outline L1 and the virtual outline V1 detected as in [Fig. 5] from the 'cuticle image' [Fig. ] as follows.

The 'outline profile' on [Fig. 6] represents the profile of the analysis outline L1 obtained by the cuticle analysis module 230 from the 'cuticle image'. And, the 'average value' on [Fig. 6] represents the profile of the virtual outline V1 detected by the cuticle analysis module 240.

As a result, the portion exceeding the 'average value' in the 'outline profile' on [Fig. 6] represents a positive deviation value for the numerical calculation module 240 to digitize, and the 'average value' in the 'outline profile' on [Fig. 6] The underlined part represents a negative deviation value for numerical calculation module 240 to digitize.

Here, when sampling is performed at a plurality of positions with respect to the positive and negative deviation values as shown in FIG. 6 , each negative deviation value and each positive deviation value can be obtained.

At this time, since each positive deviation value and each negative deviation value are added together as it is to cancel it, each positive deviation value and each negative deviation value are individually squared and then summed, and the square root of the sum of all values is 'RMS'. It can be defined as 'deviation through technique'.

'Deviation through the RMS technique' can be defined as in [Equation 1] below.

In [Equation 1], N denotes the number of 'sampling' in [Fig. 6], and e denotes each positive and negative deviation value at the position of each 'sampling'.

delete

As such, as the 'deviation through the RMS technique' is derived for the 'outline profile' in [Fig. 6], even if the surface state of the hair is slightly changed, the changed result can be clearly seen.

[Fig. 7] is an exemplary diagram showing an analysis outline and a virtual outline for a hair cuticle detected by the cuticle analysis module according to the present invention.

As a result of analyzing the 'cuticle image' by the cuticle analysis module 230, when the cuticle size (size) is significantly smaller than a preset standard (eg, indicated as 'virtual outline (V2)' in FIG. 7 ) , irrespective of the result value digitized by the numerical calculation module 240 , the result output module 250 may be configured to inform a predetermined result for the surface state of the corresponding hair.

For example, as a result of analyzing the 'cuticle image' by the cuticle analysis module 230, if the analysis outline L2 of the cuticle is significantly smaller than the virtual outline V2, which is a preset standard (size), this means that the cuticle of the hair is It means evenly reduced damaged hair. In this case, even when the value of 'deviation through RMS technique' with respect to the 'outline profile' described above in [FIG. 6] is very small, it means damaged hair.

On the other hand, the process of detecting the virtual outline V2 in [ FIG. 7 ] means that the standard of the cuticle is virtually preset through a dedicated app.

On the other hand, the cuticle measuring unit 200 according to the present invention may further include a cuticle specification normalization module 260 as shown in FIG. 2 .

The cuticle specification normalization module 260 is configured to normalize the cuticle image (eg, 10 ⁶ pixels, 10 ⁴ pixels) displayed by the display control module 220 to a preset resolution (eg, 10 ⁴ pixels).

For example, a plurality of smart devices 10 installed with a dedicated app according to the present invention, each camera unit 11 can exhibit different performance, so that the same hair for the same hair enlargement fixing unit 100 is mounted. Even when shooting in a state of being, the 'cuticle image' will be acquired at a different resolution depending on the performance of each camera unit 11 .

As a result, the analysis outline L2 detected through the cuticle analysis module 230 and the virtual outline V1 and V2 based on the analysis outline L1, L2 are different for each smart device 10. It can be shown, and this disadvantage can be overcome through the cuticle specification normalization module 260 .
