Description

Portable skin disease diagnosis device using variable wavelength of skin image information}

The present invention relates to a device for diagnosing a portable skin disease using skin image information of a variable wavelength. More particularly, the present invention relates to a portable skin disease diagnosis apparatus using a light scattered through a variable light source at the time of diagnosis. You can check the basic shape of the skin, you can check the appearance of the skin disease by using the light reflected from the skin surface through the variable light of the ambient light of the variable wavelength, and by providing the inclined illumination of the variable wavelength of the inclined surface ( Aspect) by checking the shape, it is possible to diagnose at least one or more diseases of skin pigment disease, infectious disease, skin cancer, and to obtain a three-dimensional shape information by using a photo metric, to provide a three-dimensional shape of the variable The present invention relates to a portable skin disease diagnosis apparatus using skin image information of a wavelength.

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.

In addition, the variable lighting scenario information storage module 630 stores the photographed skin disease image for each wavelength band.

Specifically, a plurality of wavelength-variable fluorescent modules 310, 510, which are formed in the first lighting group 300, the second lighting group 500, and the third lighting group 700 through the wavelength band simultaneous lighting control module 610. Two or more optical devices 310a to 310n, 510a to 510n, and 710a to 710n coupled to 710 are controlled to simultaneously light up the optical devices that emit light with the same wavelength.

In addition, since it is possible to obtain a point light source image by providing illumination for the photo metric, it provides an effect of three-dimensionally identifying the skin disease site.

On the other hand, the variable wavelength skin control unit 600,

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.

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 variable wavelength skin 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 variable wavelength 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. 12, the absorption rate is calculated by analyzing the first image image acquired when the first lighting group red light source is turned on. As a result, 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 variable wavelength 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 absorbance difference values deviate from a set threshold difference value, the skin disease is diagnosed.

More specifically, referring to FIG. 12, when the first lighting group red light source is turned on, the absorption rate is calculated by analyzing the first image image obtained, and as a result, the absorption rate is 55% and the second 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.

On the other hand, in the case of a general point, as shown in the graph on the right side of FIG. 12, the difference in absorptivity between illumination group light sources is not large.

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 in 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.

For example, the diameter of the layer in which the second lighting group 500 is disposed is greater than the diameter of the layer in which the first lighting group 300 is disposed.

That is, the second lighting group is arranged on the same plane as the first lighting group formed around the camera unit.

In this case, the second lighting group 500 includes a plurality of wavelength variable optical module 510 is formed at a predetermined interval to irradiate light to the skin, and when the light is emitted, the illumination is provided to the camera, the wavelength variable optical module 510 is a combination of two or more optical elements (510a ~ 510n) for emitting light of different wavelength bands.

Accordingly, the lighting groups are positioned on the same plane in two rows (for example, the first lighting group and the second lighting group), and the cap 400 contacts the skin to light up the optical device to provide illumination to the camera unit. Will be.

In this case, preferably, the structure of the cap may have a funnel shape in which the diameter becomes wider toward the lower side.
