[0001] The present invention relates to a tongue image acquisition apparatus using a light source of a specific wavelength band,

The present invention relates to a tongue image acquiring apparatus, more particularly, to a tongue image acquiring apparatus, more particularly, to a tongue image acquiring apparatus which closely contacts a face of a measurement subject with an acquisition apparatus, blocks light incident from the outside into the acquisition apparatus, The present invention relates to an apparatus and method for acquiring a tongue image using a light source of a specific wavelength band that can easily separate an image of a tongue and a tongue from an image of a tongue by improving the quality of the tongue image acquired by the tongue image.

Generally, seulgi is a field of Oriental medicine that diagnoses based on visual information, and it is one of the diagnostic methods that can diagnose the health condition of the testee relatively simply and inexpensively by observing the color and shape of the tongue and the suture of the testee. This is a representative diagnostic method of Oriental medicine together with the pulse, and so far, it has been done by relying on visual observation of skilled oriental medicine.

In order to diagnose a patient's illness or health status of a patient, Oriental medicine physician first examines the presence, thickness, color, and wetness of the patient, and examines the color, spots, thickness, . Sedae, a substance covered with moss, called a sutae, can be seen through its color, its degree of wetness, its thickness, its shape, and the range covered by its sutae. Thus, in oriental medicine, the tongue information of the patient is important in the determination of the health condition of the patient. Recently, it has been found that sickle is a major cause of halitosis, and studies are being actively carried out to quantitatively evaluate some of the sickle.

However, despite the fact that seborrhea is a noninvasive, safe, and simple diagnostic method, the use of visual inspection method in traditional oriental medicine has a disadvantage in that it may not be objective because it may be different according to subjectivity of the examiner. In addition, seulchin is affected by the environment such as light source, patient 's posture, physician' s health condition, and has a disadvantage of not accumulating clinical data due to limitation of quantification and standardization.

In order to quantify and standardize the tsunami through informatization of tsushin image, since 2000, there have been steady researches through policy support in Korea, China, and Japan. At present, several prototypes have been developed in Korea, and efforts for commercialization are continuing.

Conventionally, the method for evaluating the amount of the conventional technique is to measure the weight of a sling covered with moss on the tongue by scraping it with a tongue scraper and then measuring the weight using a precision scale, And evaluating the distribution area of the tongue from tongue images taken with digital imaging equipment.

According to the method of measuring the weight of the slaughter, Yaegaki and Sanada used a small spoon-shaped tongue scraper to remove the tongue covering the back of the tongue, and then use a precision scale The weight was measured and the amount of sperm was measured. Although this method is the most accurate method for measuring the amount of sling, it can cause discomfort, nausea (gag reflex) when the scraper is scratched by the scraper, and it can cause bleeding to the tongue And the like.

According to the method of visual evaluation, Gross et al. Used the method of giving the score from 0 to 3 according to the subjective judgment of the observer by visual observation of the degree of the squeezing. Bosy et al., De Boever et al. Also evaluated the severity of cramps in three stages: heavy, medium, light or none. Miyazaki et al. Used a method of assigning scores ranging from 0 to 3 according to the degree of area occupied by the surface of the tongue against the back surface area of the tongue.

Go'maz and Lundgren et al. Used the color and distribution status of slaughter to evaluate the amount of slaughter. (0 = no coating, 1 = light-thin coating, 2 = heavy-thick coating) according to the glaucoma thickness of each area observed with the naked eye, (0 = pink, 1 = white, 3 = brown, 4 = black) according to the color of the area. However, the above method is not used well because it is too cumbersome and complicated to use.

Currently, the most commonly used method for assessing the amount of sling is the Winkel tongue coating index (WTCI) method developed by Winkel et al. This was done by dividing the frontal part of the tongue into the front part of the tongue and the rear part of the tongue root and the left, ) And discoloration (0 = no discoloration, 1 = light discoloration, 2 = severe discoloration). The method is currently the most widely used because it is relatively simple to use.

 However, the WTCI method has a problem in that it is not clear to what extent the thickness is set as a valid stall distribution area. Therefore, the WTCI method relies on the subjective judgment of the observer as in the visual evaluation method, so that it is difficult to expect high reliability.

In order to overcome the limitations of the method of measuring the weight of the sling and the method of visual evaluation, Kim et al. Proposed a method of evaluating the amount of sling from digital tongue images. In order to further objectify the WTCI method, Kim et al. Calculated the ratio of the area of the tongue to the back area of the tongue from the image of the tongue obtained by photographing the tongue with a digital camera and expressed it as a percentage. However, the method of Kim et al. Has only a limitation in that it can not be regarded as a method of evaluating the thickness or amount of the suture, but only calculating the area where the suture is distributed. A method of photographing a tongue with a digital camera in a state in which light incident from the outside to the inside of the measuring apparatus is not blocked is a method of measuring a tongue of a subject by measuring the contact between the face of the subject and the measuring apparatus It is difficult to acquire an accurate tongue image because the light is irradiated to the inside of the measuring apparatus.

Example

The present invention is based on the assumption that different assumptions for the detection of the stomach area from the tongue area, that is to say the skin and the stomach, are different in fluorescence properties. Staphylococci or staphylococci may account for up to 90% of the bacterial composition, and oral epithelial cells liberated from the oral mucosa may also be used. White blood cells, various blood metabolites and food waste. When irradiated with near ultraviolet light around 350 nm, the sperm will emit weak green fluorescence.

This is because the enzymes and amino acids such as FAD, which are formed during the metabolism of various bacteria contained in the sperm, exhibit fluorescence properties, and the intensity of fluorescence is strongly related to the metabolic state and amount of the bacteria. In addition, blood metabolites such as porphyrin, which are contained in sperm, emit orange or red fluorescence. However, since the fluorescence characteristic of the skin is rarely exhibited, the use of the difference in fluorescence properties between the skin and the sperm can clearly detect the sperm region from the tongue region.
