Description

Diagnosis Device of optical skin disease

The present invention relates to an apparatus for diagnosing an optical skin disease, and more particularly, as a handy type, when diagnosing a skin of a diagnoser, it is possible to check the underlying shape of a skin disease of a diagnoser using light scattered through a contact light source. Through the light reflected from the surface of the skin, the appearance of the skin disease can be checked, and the inclined illumination can be provided to check the inclined surface (side) shape of the skin disease area of the diagnoser, thereby causing skin pigment disease, infectious disease, and skin cancer. At least one of the diseases can be diagnosed, and relates to an optical skin disease diagnostic apparatus for providing a three-dimensional shape of the shape by obtaining the three-dimensional shape information using a photo metric.

Three-dimensional shape extraction technology is a digital technology for extracting three-dimensional shape of an object in the real world.In the case of a method of displaying three-dimensional shape of an object by hand based on conventional computer graphics, an experienced designer Since the 3D model is manufactured by hand, it takes a lot of time, and there are many disadvantages in quality depending on the skill of the designer. When modeling an object in the real world, a measurement process must be performed.

In order to solve such a problem, the three-dimensional shape extraction technique is already used in many applications.

The three-dimensional shape extraction technology of an object can be classified into a contact type and a non-contact type. In the case of a contact type three-dimensional shape extraction, a high-precision three-dimensional method is performed by measuring three-dimensional coordinates while the measuring sensor is in contact with a measuring part of a restoration object. Although measurement data can be obtained, measurement is not possible for objects whose shape changes when a pressure is applied or for high temperature objects. Therefore, a non-contact three-dimensional shape extraction technique has been proposed as an alternative.

Contactless three-dimensional shape extraction technology extracts three-dimensional shape by using light reflected or transmitted from an object. In many industries, the three-dimensional shape of the product itself or surface can be extracted in real time in a non-contact manner for product quality control. There is a constant demand for technology development for a possible system.

The photometric stereo technique applies a plurality of lights to a target object sequentially and extracts a three-dimensional shape of an object using at least three images obtained by a camera. The more the number of lights, the more reliable The three-dimensional shape of the object can be extracted.

Recently, three-dimensional image is obtained by applying photometric stereo technique to three images obtained by irradiating an object with three different wavelength bands of RGB camera and R (red), G (green), and B (blue) simultaneously. Techniques for extracting information have been developed.

On the other hand, as the interest in skin care has increased, many users have confirmed the condition of the skin through various paths such as skin care rooms, massage shops, dermatologists, and used the appropriate cosmetics or medicines to manage the skin.

People's skin conditions vary greatly depending on the season, and since individual variations vary, accurate diagnosis is of paramount importance for proper prescription.

For the diagnosis of skin conditions, dermatologists and clinics are equipped with specialized medical equipment, enabling diagnostic activities such as taking enlarged photographs of pores.

However, due to the increased interest in skin care, the user's level of knowledge about the skin has also increased, and users want to know more about the condition of their skin or the change of the condition of the skin.

Nevertheless, it is very cumbersome to simply visit the clinic on a regular basis to monitor the condition of the skin and to find out the changes in the use of beauty products.

Therefore, it is necessary to prepare a method for allowing users to easily check and diagnose their skin condition while carrying.

In addition, cameras, sensors, and the like, which provide comprehensive information about conventional skin, are simply photographed by the operator manually and obtain information.

In addition, when measuring the approximate condition of the facial skin has been obtained by analyzing a 2D image with a high-resolution camera, in order to obtain a comprehensive information about the facial skin contact local imaging sensor using a sensor other than a high-resolution camera The hassle has to be retaken.

In this case, there was an inconvenience in that a process of detaching the face from the apparatus after photographing the facial skin in front of the high resolution camera and then manually contacting the photographing local photographing camera was performed.

On the other hand, recent cosmetics shops, dermatology, and skin care centers to measure and diagnose their own skin condition to facilitate selection of cosmetic products that are suitable for their skin condition, or to discover problems in their skin condition and find solutions. There are many types of skin diagnostics available to help you find them.

Among these, skin diagnosis apparatuses using a diagnostic lamp for diagnosing a skin condition are commonly used, in particular, by irradiating light of a specific wavelength to the skin and analyzing a unique fluorescent color of the skin irradiated with the light.

What is mainly used as said diagnostic lamp is an ultraviolet lamp.

Conventional skin diagnosis apparatuses using ultraviolet lamps need to darken their surroundings when ultraviolet rays are irradiated so that ultraviolet rays can be efficiently irradiated to desired skin areas.

Accordingly, a device for diagnosing the skin condition of the face, which is commonly seen in cosmetics stores, etc., has a cylindrical black cloth in which a diagnostic lamp is mounted in a box having an open front surface and light is not easily transmitted along the outer circumferential surface of the open front side of the box. By attaching, the subject to be diagnosed with the skin condition wrapped the cloth around the head and brought the face closer to the box equipped with the diagnostic lamp, so that the surroundings were darkened to measure and diagnose the skin condition.

Such a conventional skin diagnosis device is not sure of darkening, so there is a fear that measurement and diagnosis cannot be made efficiently, and since the subject has to wrap the cloth around the head as described above, the shape of the hair may be broken, and the diagnosis itself is reluctant. Or you may think that process is cumbersome.

In addition, when the cloth is torn or dirty, there is a inconvenience to replace frequently.

On the other hand, recently, attempts have been made to check the condition of the skin by radiating light onto the skin and analyzing the light information, but what light is to be irradiated, what light is to be detected, and the detected light information. There is no established method of how to analyze the skin, and therefore urgent development of a method for diagnosing skin using this principle and its device is required.

In addition, in the conventional general 3D object surface photographing apparatus, since the appearance size is large and the price is expensive, general skin shops or individual users do not have the difficulty to check their skin condition at any time. The device also has a problem that can not provide a variety of illumination wavelength band, it is not possible to determine the various trouble state on the surface of the object.

Therefore, there is a need to provide a device that can more easily and precisely provide the surface state of the skin disease as an image image.

Meanwhile, in the United States, one person dies of skin cancer every hour due to skin cancer.

Each year, one in five people are diagnosed with skin cancer, and five million people are being treated for skin cancer, making skin cancer a very serious social problem.

It is important to check these skin cancers regularly because they have no symptoms.

As shown in FIG. 1, skin cancer is mainly examined with a naked eye or a microscope, and when a skin cancer is suspected, a biopsy is performed. In particular, a biopsy is a pain and wound to remove skin tissue, and a lot of cost and time. need.

Recently, a technique for diagnosing skin cancer using the spectral characteristics of the laser has been developed, but all of these methods have to visit a hospital.

In other words, it is difficult to go to the hospital every time to check periodically.

In addition, as shown in Figure 1, it is impossible for the general public to visually judge the point and skin cancer is similar in shape and size.

In the case of Figure 2, even if you go to the hospital to check the eye with a handy type diagnosis by the doctor to diagnose skin cancer, but the hit rate is less than 90%, more accurate diagnostic technology is required.

For setting a section of a plurality of lights formed in the first lighting group 300, the second lighting group 500 or the first lighting group 300, the second lighting group 500, the third lighting group 700 Section setting module 620,

At least one module of the metric lighting control module 630 for acquiring the set lighting control information for each section or lighting control information for each group to provide a control signal to a plurality of lights existing in the corresponding section or group; The first lighting group 300, the second lighting group 500, or the first lighting group 300, the second lighting group 500, and the third lighting group 700 may be operated in different ways. It is characterized in that to control, and to simultaneously or sequentially obtain images from the camera.

The group lighting control module 610 may be applied to the first lighting group 300, the second lighting group 500, or the first lighting group 300, the second lighting group 500, and the third lighting group 700. The collective lighting control or group lighting sequence control of the formed multiple lights is performed.

For example, if the first lighting group 300 on, 0.5 seconds after the second lighting group 500 on, all the lights forming the first lighting group 300 is turned on, 0.5 seconds later All of the lights forming the second lighting group 500 is turned on.

The section setting module 620 may include a plurality of sections formed in the first lighting group 300, the second lighting group 500, or the first lighting group 300, the second lighting group 500, and the third lighting group 700. To set up a section of lights.

Referring to Figure 9, it is set to the sections A ~ D, in the case of the A section A11 ~ A13 lighting of the first lighting group, A21 ~ A24 lighting of the third lighting group, A31 ~ A35 of the second lighting group It will include lighting.

This is defined as section-specific lighting control.

In addition, the metric lighting control module 630 acquires lighting control information for each section or lighting control information for each group and provides a control signal to a plurality of lights existing in the corresponding section or group.

In addition, lighting control may be performed by dividing into specific sections of a specific group.

For example, in the A section of the first lighting group, only A11 to A13 lighting is turned on.

Therefore, the light paths of the first and second lighting groups can be controlled to operate differently, so that images can be acquired simultaneously or sequentially from the camera.

Meanwhile, the section setting module 620 may set a section and may set an illumination group existing in the section.

That is, the section setting and the group setting can be performed simultaneously, such as only the first lighting group of the first section A is turned on, only the second lighting group of the section A is turned on after 0.5 seconds, and only the third lighting group of the section A is turned on after 0.5 seconds. It can also be configured to do so.

Therefore, a simultaneous lighting signal can be sent to a plurality of lights existing in all groups, and the lighting signal can be sent by dividing into groups, by sections, or by dividing into specific sections of a specific group, and can also send lighting signals sequentially. .

Through this, images of various wavelength bands can be obtained, and various optical paths can be obtained at the same time, so that the surface of the skin disease site can be classified by using the characteristic that the surface of the skin disease site reacts differently according to the wavelength band. By extracting the image information to obtain three-dimensional information of the skin disease site, it is possible to provide a fine surface shape and texture in the three-dimensional shape of the skin disease site.

On the other hand, according to another additional aspect, the skin disease control unit 600,

And a memory module 640 configured to store the set section-specific lighting control information or group-specific lighting control information and shape information of the photographed skin disease region.

It may be configured to further include an image processing module for processing into a three-dimensional shape through the image information of the skin disease region stored in the memory module.

For example, if the subject is a skin cancer site, the skin cancer may be analyzed by scanning a specific wavelength band that fluoresces the skin cancer.

In addition, when the image information according to the optical path is extracted, three-dimensional information of skin cancer can be obtained.

At this time, the skin disease control unit 600, in order to obtain three-dimensional information, further comprises a three-dimensional shape generating module, surface shape generating module, three-dimensional surface surface matching module.

Specifically, the three-dimensional shape generating module is to generate a three-dimensional shape by obtaining a 3D value when the camera is a TOF camera, the surface shape generating module is to generate a surface shape based on the photometric image information. .

At this time, the surface shape information is matched to the three-dimensional shape information generated from the three-dimensional shape generating module and the surface shape generating module by the three-dimensional shape surface matching module.

In other words, when matched, it is possible to provide a fine shape and texture of the skin cancer surface.

On the other hand, according to another additional aspect of the present invention, the skin disease control unit 600,

And a wireless communication module 650 for transmitting the shape information of the skin disease target surface stored in the memory module 640 to the external terminal 2000 via wireless communication.

Therefore, the shape information of the skin disease target surface stored in the memory module 640 is transmitted to the external terminal through wireless communication.

As described above, when configured, it is possible to check in real time the image information of the skin disease target surface being photographed through the screen of the external terminal (2000).

In addition, by providing the matched three-dimensional stereoscopic image to the cloud server 3000 configured remotely, the cloud server to generate the surface diagnosis information on the skin disease.

As described above, when the user is configured to access the cloud server anytime and anywhere through an external terminal having a corresponding skin disease surface diagnosis information, for example, a smart device, the corresponding surface diagnosis information is obtained.

To this end, the diagnostic app will be mounted on the smart device.

In other words, by being able to diagnose a more precise skin condition, it is possible to prevent skin diagnosis errors.

On the other hand, the skin disease control unit 600,

The absorption rate of each image image information is extracted by extracting the image image information obtained by the lighting of the first lighting group, the image image information obtained by the lighting of the second lighting group, and the image image information obtained by the lighting of the third lighting group. The calculation further includes a skin disease diagnosis unit for diagnosing a skin disease when the difference in absorption rate is higher than the threshold difference value.

More specifically, the skin disease control unit 600, specifically the skin disease diagnosis unit,

After selecting one lighting group among the first lighting group 300, the second lighting group 500, the third lighting group 700, and lighting the light source of the wavelength band absorbed by the skin disease in the lighting group, Provides a shooting signal to the camera unit to obtain a video image,

After a certain period of time, the light source of the wavelength band that is not absorbed by the skin disease in the selected lighting group is turned on, and a photographing signal is provided to the camera unit to acquire a video image.

The absorption rate difference value of the obtained two image images may be determined, and when the determined absorption rate difference value deviates from a set threshold difference value, the skin disease may be diagnosed.

For example, the first lighting group 300 is selected, the red light source, which is a light source of a wavelength band absorbed by the skin disease in the lighting group, is turned on, and a photographing signal is provided to the camera unit to acquire an image image.

Thereafter, after a predetermined time, the green light source, which is a light source of a wavelength band that is not absorbed by the skin disease in the selected first lighting group, is turned on, and a photographing signal is provided to the camera unit to acquire an image image.

Subsequently, the absorbance difference values of the obtained two image images are determined, and when the determined absorption difference values deviate from a predetermined threshold difference value, the skin disease is diagnosed.

More specifically, referring to FIG. 11, as a result of analyzing the first image image obtained when the first lighting group red light source is turned on, the absorption rate is calculated, and the absorption rate is 55% and the first lighting group green light source is As a result of analyzing the acquired second image image when it is turned on and calculating the absorption rate, when the absorption rate is 10%, the threshold difference value is set to 40%.

In this case, since the difference between the first image image absorption rate of 55% and the second image image absorption rate of 10% is 45% and exceeds the threshold difference value of 40%, this is analyzed (diagnostic) as a skin disease (for example, skin cancer). will be.

In the case of the above absorption rate calculation, in general, if the light emission is 100% and the light reception is 45%, the absorption rate will be 55% because it means that the skin disease (for example, skin cancer) has been absorbed.

Since the technique of calculating the absorption rate through the video image is known to those skilled in the art of processing the video image, a detailed description thereof will be omitted.

On the other hand, as another lighting group lighting example, the skin disease control unit 600, specifically, the skin disease diagnosis unit,

After selecting one lighting group among the first lighting group 300, the second lighting group 500, the third lighting group 700, and lighting the light source of the wavelength band absorbed by the skin disease in the lighting group, Provides a shooting signal to the camera unit to obtain a video image,

After a certain period of time, after turning on the light source of the wavelength band that is not absorbed by the skin disease in any one of the lighting group except the selected lighting group, and providing a photographing signal to the camera unit to obtain a video image,

The absorption rate difference value of the obtained two image images may be determined, and when the determined absorption rate difference value deviates from a set threshold difference value, the skin disease may be diagnosed.

For example, the first lighting group 300 is selected, the red light source, which is a light source of a wavelength band absorbed by the skin disease in the first lighting group, is turned on, and a photographing signal is provided to the camera unit to acquire an image image. do.

Thereafter, after a predetermined time, the green light source, which is a light source of a wavelength band not absorbed by the skin disease in the second lighting group except the selected first lighting group and the second lighting group, is turned on, and then the camera unit is turned on. The imaging signal is provided to acquire a video image.

Subsequently, the absorbance difference values of the obtained two image images are determined, and when the determined absorption difference values deviate from a predetermined threshold difference value, the skin disease is diagnosed.

More specifically, referring to FIG. 11, as a result of analyzing the first image image obtained when the first light group red light source is turned on, the absorption rate is calculated, and the absorption rate is 55% and the second light group green light source is As a result of analyzing the acquired second image image when it is turned on and calculating the absorption rate, when the absorption rate is 10%, the threshold difference value is set to 40%.

In this case, since the difference between the first image image absorption rate of 55% and the second image image absorption rate of 10% is 45% and exceeds the threshold difference value of 40%, this is analyzed (diagnostic) as a skin disease (for example, skin cancer). will be.

On the other hand, in the case of a general point, as shown in the graph on the right side of FIG.

In the case of dots, since the probability of absorbing light is significantly lower than that of skin cancer, the difference in absorption rate is not large when analyzing image images photographed after lighting by the first lighting group light source, the second lighting group light source, and the third lighting group light sources.

On the other hand, the absorption threshold difference value is collected by configuring the machine learning skin disease learning unit for learning and setting the set number of skin diseases (for example, skin cancer) using a machine learning method, by configuring the cloud server 3000, By learning the absorption rate in the skin disease image, the optimal absorption threshold difference value is set to increase the accuracy of skin disease diagnosis.

In other words, through the machine learning skin disease learning unit is to increase the accuracy of skin disease diagnosis.

According to the present invention, as a handy type, at the time of diagnosing the skin of the diagnoser, the basis shape of the skin disease of the diagnoser can be confirmed using light scattered through the contact light source, and the skin disease using light reflected from the surface of the skin through the ambient light source. It is possible to check the appearance of the, and by providing a tilted light to determine the inclined surface (side) shape of the skin disease area of the diagnoser, so that at least one of the skin pigment disease, infectious disease, skin cancer can be diagnosed By doing so, anyone can easily photograph the surface of a skin disease object at a low price, thereby exerting an effect of confirming the surface state in a three-dimensional shape and increasing the probability of diagnosing skin cancer in case of skin cancer.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the above-described specific embodiment, the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims.
