Description

DIAGNOSTIC METHOD OF BPPV USING PUPIL AND IRIS

The present invention relates to a method for diagnosing and treating dizziness, and more specifically, using a wearable device, Anjin and a terminal, to diagnose whether the user has dizziness and dizziness, and to allow the user to treat dizziness on his own according to the results. The present invention relates to a method for diagnosing dyslexia using a pupil and an iris.

This is a small chunk of calcium in the ovarian sac in the vestibular organ of the inner ear. When the stone is removed from its place and moves to the semicircular canal, lymphatic fluid in the semicircular canal has abnormal fluidity due to the mass of calcium affected by gravity, which causes dizziness. This happens.

These symptoms are called dyslithiasis, and most of the treatments for dyslithiasis use dichroic replacement, which reduces the displaced stones to their original position by changing the body position. Since the treatment method varies depending on the area and direction of the semicircular canal where the stone is located, proper and effective stone replacement is possible only when the location of the stone is accurately diagnosed.

In order to accurately diagnose the location of the stone, it is necessary to diagnose the semicircular canal where the stone is located by observing the direction of the eyelid caused by changes in the head. Anjin refers to corrective eye movements that appear to correct when the image of an object deviates from the center of the retina by abnormalities in the peripheral vestibular system, such as dysplasia, as well as various ocular movement systems that reach the cerebrum. As a result, a characteristic nystagmus appears when the head changes, so it is possible to diagnose the location of the stone.

As a feature of Anjin according to the location of the stone, when the stone is located in the lateral horizontal semicircular canal, the horizontal component of the eczema occurs, and it has a characteristic that the direction changes depending on the left and right heads in the supine position. Geostatic Torsional Nystagmus appears due to the Dix-Hallpike technique, where the head is turned to the lesion in a sitting position and the head is dropped to the suspension level. do.

For reference, Dix-Hallpike refers to a method of examining the characteristics of the nystagmus that appears when the lesion-side ear is transformed to a specific position with the ear downward.

Dizziness caused by dizziness can be treated relatively easily through the corresponding dichroic replacement, but there is a discomfort that requires direct visits to the hospital for accurate diagnosis. It is reported that there is a hassle of having to visit a hospital whenever a relapse is suspected.

Accordingly, there is a need for a method for accurately diagnosing the location of a patient suspected of dyscalculia and allowing the patient to appropriately perform a proper displacement procedure according to the location.

In addition, patients who complain of dizziness cause specific eye movements due to abnormal vestibular ocular reflexes, so clinicians use it for diagnosis by determining whether eye movements due to head changes are abnormal.

The eyeball has a three-dimensional form of motion, horizontal and vertical movements on the vestibular reflex motion, and rotational motion. Measurement of ocular momentum that has been commercialized to date has been carried out through examination through an examiner's eye, Frenzel glasses, an electro-osmulator or a video oscillator. However, in the method of directly inspecting the examiner or using the prezel glasses, the movement of the eye may be observed when the amount of change in the eyelid is large, but in the opposite case, measurement is difficult.

Nevertheless, video ophthalmographs have been widely used as a diagnostic method to date, and include a method for diagnosing and observing ocular movement through a video, and horizontal, vertical, and rotation through graphs by attaching an ophthalmic examination device to the video ophthalmograph. There is a way to display a 3-axis measurement of exercise and use it for diagnosis. However, in the latter case, there is an advantage that objective measurement is possible, but for 3-axis analysis, the image acquired through a separate image sensor mounted therein is processed to measure the 3-axis eye movement. Therefore, the sensitivity is determined according to the resolution, frame rate, and image processing accuracy of the internally mounted image sensor, and the price is high due to the technical problem of separately measuring the angular velocity (deg/sec) measured along each axis of eye movement. Then there is a problem that is difficult to be used in general. On the other hand, a simple video stabilizer without this function is relatively inexpensive and widely used, but it requires advanced training for diagnosis.

4. Start shooting now. The time required is about 20 seconds. Beep~

Also, in the case of horizontal semicircular canal disease test

"Let's lie back. Turn your head to the right with your right ear facing down. Turn your head to the left with your left ear facing down. Sit back and look straight ahead." For example, in the case of an examination of the posterior annular canal dysentery, "Let's lie back and drop your head under the bed while turning your head 45˚ to the right in a sitting position. Sit up again. Sit back. ˚ Lying on your back while turning, drop your head under the bed. Get up again and sit down.” It can be provided by voice guidance or video guidance.

In addition, through the jinjingi control unit 290 of the control unit 200, such voices can be edited and the speed of sentence reproduction can be set according to the state of the subject.

The image processing unit 250 may image-process one or more captured images provided by the optical/imaging unit 30, that is, ocular images for each of both eyes of the subject. The image processing unit 250 may extract the outline of each eyeball and the pupil and the center point of the pupil as a result of image processing. The pupil center point is extracted as coordinates and constitutes vibration information.

Also, the image processing unit 250 may extract a feature point for the iris or pupil of the subject as a result of image processing, and extract the degree of distortion of the feature point of each frame at an angle.

Specifically, for extracting vibration information, the eyeball image of a black and white or binary image is processed frame by frame to extract the coordinates of the center point of the pupil in each frame, and for the extraction of torsion information, the image of the iris or pupil is processed frame by frame to iris or The angle is extracted by comparing the patterns for the feature points of the pupil.

First, in order to extract the center point coordinates of the pupil, the first pupil center point coordinates are set from the eyeball image of the first acquired subject's black and white or binary image, and the corresponding frame in the eye image of the frame that is continuously input based on the first pupil center point coordinates. To calculate the coordinate value of the pupil center point.

" 로 표시), 이어 입력되는 프레임의 중심좌표를 최초 중심 좌표(점선으로 표시)대비 변화 정도로 이미지로 표시한다.When the reference drawing for calculating and comparing the coordinate values of the pupil center point of FIG. 6 is viewed from the left, the coordinates of the center point of the first pupil are extracted from the pupil image captured by the binocular camera 31 ("

Then, the center coordinates of the input frame are displayed as images with a degree of change relative to the initial center coordinates (indicated by dotted lines).

Such a display may be displayed by accumulating center marks for each input frame, but for observation, only two center values may be compared and displayed based on the previous center value and the current center value.

The center point coordinates of the first pupil are respectively extracted from the subject's eye outline and the pupil outline line from the eye image of the black and white or binary image of the first frame, and the coordinates of the first pupil center point are set based on the pupil outline line, and then the eyeball The horizontal points on both sides of the subject's eye are set based on the outline line, and the distance from each of the horizontal points on both sides to the coordinates of the initial pupil center point is calculated.

In addition, the black-and-white or binary image of the first frame of the eyeball image outputs a display image informing the examination from any one of the subject's binocular eyes, and induces the subject's gaze on the display image, and then displays The first eyeball image may be acquired by photographing each of both eyes of the subject who watches the image.

In addition, the calculation of the pupil center point coordinate value is obtained by photographing the eyeball according to the subject's gaze movement, obtaining an eyeball image, setting a pupil outline line in the eyeball image, and calculating the pupil center point coordinates based on the pupil outline line (x, y).

The extraction of these coordinates analyzes an image at 30 frames per second for about 5 to 30 seconds.

When the total frame of the image is calculated at 30 frames per second, vibration information is configured by extracting coordinates of about 900-1200 frames.

And by comparing the change in the coordinates of the initial pupil center point according to the calculated pupil center point coordinates, the center distance of the pupil is one or more of 1 mm or more in the x-axis or y-axis, and the pupil area is 50% or more of the total area. Only extract.

When the pupil area is less than 50% of the total area, the image outside the analysis range is excluded based on the outer line of the eyeball. If the residual pupil image is less than 50%, the center value of the pupil cannot be extracted, and 1mm The following cases are excluded because they may arise from natural normal eye movements regardless of the eye movement.

In addition, the image processing unit 250 extracts an angle to compare the degree of distortion.

In order to calculate the degree of torsion, the pupil or iris region is extracted from the eye image of the input black-and-white or binary image, the feature points are set from the pupil or iris, and the feature points of the continuously input frame are inclined relative to the first feature points. It works to calculate the angle.

Preferably, an infrared launching device such as an LED and a lens for recognizing reflected pupils or irises can be used.

Hereinafter, for convenience of description, a method of extracting feature points from an iris image and calculating an angle will be mainly described.

First, looking at the reference drawing for comparing the iris pattern of FIG. 7 to calculate the angle of change, only the iris region is extracted from the input eye image of the black and white or binary image, the feature points are set in the iris, and the frame is continuously input compared to the initial feature point. The feature point is operated to calculate an angle inclined relative to the initial feature point.

These irises can be distinguished from other irises by long strip-shaped nets (comb-shaped ligaments), red fibers, eyelash-shaped projections, serpentine vascular system, ring-shaped circles, and corona-shaped surrounding the pupil. There are ligaments, iris-specific colors, and spots, and these characteristic points have different biological patterns for each person.

Therefore, in the present invention, any one of the feature points of the iris may be selected and compared, but in order to easily measure the twist angle of the iris, it is preferable to select and compare feature points capable of measuring the twist angle, such as a long band-shaped network and a vascular system. It is preferable, but not limited to, that the entire pattern including the feature points may be compared.

In addition, since these feature points are provided with prominent points for each subject, it is more preferable to set a new feature point for each subject if necessary.

When the feature points are set as described above, the image processing unit 250 extracts the feature points of the iris or pupil using the binary image processing technique from the first eyeball image to calculate the torsion angle, and the feature points of the original image through pattern recognition It is to extract the degree of contrast distortion at an angle.

Referring to the drawings, from the left, in order, the feature points of the iris are extracted from the color eyeball image on the left side through pattern recognition and the feature points of the iris measured in the next frame are compared with each other to indicate the degree of change, and through this The torsional information can be extracted.

Torsional information, like vibration information, analyzes 30 frames per second for about 5 to 30 seconds.

When the total frame of the image is calculated at 30 frames per second, torsion information is constructed by extracting coordinates of about 900-1200 frames.

Of course, the display control unit 260 may control the second display spirit displayed on the right area of the first display 110 to be displayed while moving in the first direction or the second direction, and the first direction is based on the subject. The left direction of the area and the second direction may be the right direction of each area based on the subject.

In addition, the display control unit 260 may control the illuminance of the display image to adjust the distance between the subject and the image.

For example, the display control unit 260 may display the display image of each region of the first display 110 in low light, so that the subject can recognize that the display image is displayed at a predetermined distance apart. Normally, in the case of an anesthesia examination, since a separation distance of approximately 1 m between the subject and the image is required, the display control unit 260 is configured to recognize that the display image of the first display 110 is displayed at a distance of approximately 1 m. The illuminance can be controlled.

The photographing control unit 270 may control the photographing operation of the camera of the optical/photographing unit 30. Accordingly, the camera of the optical/shooting unit 30 can shoot each of both eyes of the subject at least once under the control of the shooting control unit 270.

After the posture correction and the focus correction of the subject are completed, the photographing control unit 270 may control the photographing operation of the camera of the optical/photographing unit 30. Posture correction and focus correction may be performed by providing a voice command to the subject through the above-described voice output unit 240.

The calibration unit 280 is the initial value of the subject's examination based on the results of the processing of the image processing unit 250, that is, the outline of the pupil's ocular and pupil outlines and the pupil center point coordinates extracted from one or more ocular images of each subject. You can control the calibration to set.

The calibration unit 280 may calculate the amount of change in the initial pupil center point coordinates and the initial pupil center point coordinates based on one or more pupil center point coordinates provided by the image processing unit 250, and the subject may be tested based on the calculated change amount of the pupil center point value The maximum pupil motion value of can be set, and this can be set as the initial test value of the subject.

The installation and other contents of these apps are the same as the application installation of Ajinjin, so a detailed description will be omitted.

The key input unit 530 is configured to input data for the corresponding key through a touch screen or keypad, but executes a key necessary for normal communication and a service necessary for exercise and dietary prescription for diagnosis and prevention of dementia of the present invention. And a specific button for displaying and displaying.

The terminal display unit 520 is operated as a display device that displays data received through the normal communication interface 510, but in the present invention, it is configured to display contents necessary for a diagnosis process and diagnosis results of Anjin by driving an app. ,

The coordinate processing unit 580 determines the degree and direction of vibration using the (x,y) coordinates, which are vibration information received through the communication interface unit 510, and transmits them to the terminal control unit 540.

The direction of vibration can be expressed as right (outside) and left (inside), up (up), down (down).

The angle processing unit 590 extracts the direction of torsion using the angle, which is torsion information received through the communication interface unit 510.

The direction of torsion is expressed as intorsion (external rotation) or extorsion (external rotation).

Intorsion (internal rotation) means that the upper part of the vertical spectacle line rotates toward the center of the face, and the upper pole of the eyeball rotates toward the nose, and extorsion (external rotation) the upper part of the vertical spectacle line is inclined with respect to the midline of the face It means that the upper pole of the eye rotates toward the ear.

The terminal control unit 540 drives an application stored in the user app unit 550 according to a specific button input of the key input unit 530 to display the stored data, or through the communication interface 510. It controls to display the data transmitted and received from the anjingi 100 on the terminal display unit 520.

First, the terminal control unit 540 operates to receive the measured data from the anjingi 100 and determine the presence and absence of anjinjin and display the result.

The method for diagnosing ocular anxiety according to these test items is briefly described as follows.

In general, Anjin can be tested in five ways, and can be divided into diagnosing peripheral and central disease and diagnosing dysplasia.

Items for diagnosing peripheral and centrality include spontaneous nystagmus, zhusianjin, and nystagmus after rotation of the head. As a method of diagnosing dysplasia, after reporting the direction of nystagmus by giving a change in position (stimulation of head position) (irritation) There is a method of judging by the dichotomy of the half-ring tube, the lateral half-ring tube, and the front half-ring tube.

First, spontaneous nystagmus is a nystagmus that occurs when a subject sits still and is looking at the center (in the dark state) through the nystagmus 100. Based on this, it can be diagnosed as the peripheral nervous system and central nervous system nystagmus.

For example, from the vibration information received from the image processing unit 250 of the jinjingi, if it is determined that the direction of vibration is jinjin toward the right, the right lateral semicircular canal is stimulated or the left lateral semicircular canal (LSCC) is suppressed or Diagnosis by, and when the chin to the left occurred, it can be diagnosed that the left lateral semicircular canal is stimulated or the right lateral semicircular canal is inhibited.

In other words, spontaneous nystagmus can be diagnosed as dizziness when horizontal nystagmus due to an abnormality in the peripheral organ called the Bangori duct.

In addition, it can be diagnosed that the central nervous system is dizzy when an upward or downward nystagsm occurs without horizontal nystagmus (left or right).

In addition, even if the eyelid that turned left when observed for 1 minute suddenly changes the direction to the right, it is diagnosed as the central nervous system eyelid.

In addition, the diagnosis of central nervous system nystagmus can be diagnosed even if an exorsion or intorsion occurs without changing the position (head movement).

In addition, the safety of the gaze is 30 degrees on the right and 30 degrees on the left in a sitting position, and then when the left eye is stronger than the horizontal eye (left eye), when the left eye is stronger, the left eye is stronger. Diagnosed as deterioration (insufficiency) of the lateral annular duct and, conversely, when the left eye is larger in the situation where a spontaneous nymph directed to the left appears, it is diagnosed as dysfunction of the right lateral annular duct, and when viewed to the left, it is turned to the left. It is diagnosed as a central nervous system nystagmus when a horizontal nystagmus is directed and when it is viewed to the right, and an ocular gysm to the right occurs.

In order to test for dysentery, the patient is diagnosed by looking at the direction of the nystagmus while changing his position, and can be diagnosed through a Dix-Hallpike test and a rolling test.

The Dix-Hallpike test allows you to go down from the bed while lying on your back with your head turned 45 degrees to the right to sit down to examine the right back half-ring tube, and turn your head 45 degrees to the left to check the left back half-ring tube. After lying on your back, make your head go faster than the edge of the bed.

When the right dix-hall is in the direction of the right extension and upbeating is observed at the same time, it is diagnosed that the right half ring tube is stimulating while the right half ring tube is stimulating. When the left dix-hall is left, it is in the left extorsion direction and upbeating If they appear together, you can diagnose that there are stones in the left posterior annulus.

In addition, through rolling test, it is possible to diagnose the presence or absence and dizziness of the collateral tube.

Rolling test is a method of examining the eyelids by placing the subject's head on the bed and turning the head to the left or right by more than 45 degrees. Turned to the left ◎ Horizontal eyelid to the left occurs, and horizontal to the right when turned to the right By comparing the size of the nystagmus (eg, geotrophic) and comparing the size of the nystagmus, diagnose the presence of a stone in the right lateral semicircular canal if the right side is larger, and diagnose the presence of the stone in the left lateral semicircular canal when the left side is larger.

In addition, when the left eye turns to the right, and the left eye turns to the right when it is turned (ageotrophic), compared to the size of the eye, the right side is larger, and there are stones in the left lateral annulus. To diagnose, if the left side is larger, it is to diagnose the presence of a stone in the right side lateral semicircular canal.

As described above, the terminal control unit 540 outputs analysis results necessary for diagnosis, such as the presence or absence of horizontal oscillation (vibration to the left and right), left and right abduction, and up and down vibration as a result of processing by the coordinate processing unit 580 and the angle processing unit 590.

In addition, the terminal controller 540 designates a specific oscillator from a plurality of oscillators to communicate using the IP stored in the IP storage unit 560 with a unique identification number for data transmission/reception or communication with other terminals.

Hereinafter, a method of diagnosing dyslithiasis using a pupil and an iris using an jinjingi and a terminal according to an embodiment of the present invention described above will be described.

Figure 5 is a flow chart for explaining a method for diagnosing dysentery using a pupil and an iris according to an embodiment of the present invention, as shown in the present invention, the method for diagnosing dysentery is examined by wearing the jinjin 100 to the subject It operates to diagnose dyslexia by receiving and analyzing vibration information and torsion information transmitted according to the item.

First, by processing the image received from the binocular camera 31 of the jinjingi 100 worn on the face of the subject to extract vibration information and torsion information (S100), the vibration information and torsion information extracted in step S100 to the diagnostic terminal Transmitting (S200), the diagnostic terminal diagnoses dyslexia using the received information (S300).

In step S100, in order to extract vibration information, an eyeball image of a subject is photographed through the binocular camera 31 of the eye detector (S110).

The photographing of the eyeball image in step S110 is guided to obtain the eyeball image through the voice guidance or the image through the voice output unit 240 or the first display 110 according to the set diagnostic item.

Of course, before setting the actual diagnosis items, it is needless to say that the calibration process can be performed to increase the accuracy of diagnosis.

The photographing control unit 270 controls the optical/shooting unit 30 to photograph the eyeball image, and receives the eyeball image through the binocular camera 31.

When the image of the eyeball is received in step S110, the eyepiece control unit 290 processes the image of the eyeball received by the image processing unit 250 by frame (S111) and extracts the coordinates of the center point of the pupil in each frame (S112).

Since the center point coordinates of the pupil in step S112 are the same as the operation of extracting the center point coordinates of the pupil disclosed in the above-described image processing unit 250, detailed description thereof will be omitted.

Briefly, an eyeball outline line and a pupil outline line are respectively extracted from the eyeball image of the first frame, the coordinates of the initial pupil center point are set based on the pupil outline line, and then the subject is examined based on the eyeball outline line. Set the horizontal points on both sides of the eye, and calculate the distance from each of the horizontal points on both sides to the coordinates of the initial pupil center point.

Subsequently, in the image frame of the continuously input eyeball, the eyeball according to the subject's gaze movement is photographed to obtain an eyeball image, a pupil outline line is set in the eyeball image, and the pupil center point coordinates based on the pupil outline line (x ,y).

Similarly, the center distance of the pupil is at least one mm or more, and only the coordinates when the pupil area is 50% or more of the total area are extracted.

The vibration information is constructed by extracting the coordinates of the pupil center point from the eyeball image of about 30 frames per second.

That is, in order to extract the center point coordinates of the pupil, the initial pupil center point coordinates are set from the frame eye image of the first acquired subject, and the pupil center point coordinates of the frame in the eyeball image of the frame continuously input based on the initial pupil center point coordinates. By calculating the value, the vibration information is composed of (x,y) coordinate values.

That is, it is possible to detect the edge of the pupil in real time by using a continuously input eyeball image, and extract the central value and store it in an array.

On the other hand, in order to extract the torsional information, the image processing unit 250 processes the image of the iris or pupil from the image of the eyeball received through the binocular camera of the jinjingi frame by frame (S113), and patterns for the iris or eye feature points in each frame Compare and extract the angle (S114).

In step S113, the feature points of the iris or pupil are extracted from the color image of the input eye using a binary image processing technique, and the distortion with the original image is measured through pattern recognition, and then the degree of twist is extracted at an angle in step S114. do.

The torsional information in step S113 is also the same as the process of extracting the degree of torsion initiated by the image processing unit 250 at an angle, so a detailed description thereof will be omitted.

In addition, although the feature points of the iris and the pupil may be respectively extracted or simultaneously extracted, torsional information may be calculated, but in the present invention, the method of extracting the feature points of the pupil is explained by describing a method of extracting the feature points of the iris. I want to.

Briefly, only the iris region is extracted from the ocular image of the input color image, the feature points are set in the iris, and the feature points of the continuously input frame compared to the first feature points are operated to calculate an angle inclined relative to the first feature points.

The characteristic features of these irises are long strip-shaped nets (comb-shaped ligaments), red fibres, eyelash-shaped projections, serpentine vascular systems, ring-shaped circles, corona-shaped ligaments surrounding the pupil, and iris-specific colors. , There are spots, etc., and one or more of these feature points is set.

When the feature points are set, the feature points of the iris are extracted using the binary image processing technique from the first eyeball image, and the twist angle is measured by comparing with the feature points of the original image through pattern recognition.

In step S200, the extracted vibration information and torsion information are transmitted to the diagnostic terminal 500 by performing step S100.

That is, when the vibration information and the torsional information are extracted from the image processing unit 250, the Anjingi control unit 290 stores the extracted information for each frame or for information on two or more frames in an array, and then transmits the information to the diagnostic terminal 500. You can.

Specifically, the vibration information extracted by performing steps S110 to S114 is transmitted to the communication interface unit 510 of the diagnostic terminal 500 through the communication unit 220 (S210), and the extracted twisting information is also transmitted through the communication unit 220. It is transmitted to the communication interface unit 510 of the diagnostic terminal 500 (S220).

When the vibration information and the torsion information are received through the communication interface unit 510 in step S200, the terminal control unit 540 of the vibration terminal determines whether Anjin is present and Dix-Hallpike inspection items based on the received information. Accordingly, when a checkup is performed, the presence or absence of a heterogeneous tube is determined, and a process of determining the presence or absence of a lateral semicircular canal is performed through a rolling test (S300).

To this end, the diagnostic terminal uses the received vibration information and torsional information to measure the state of the subject moving inward, advancing outward, moving upward (elevation or sursumduction), moving downward (depression or deorsumduction), and the eyeball. Make sure that the upper pole judges one or more of the following: exorsion (excycloduction) moving toward the ear and intorsion (incycloduction) moving toward the nose,

As described above, the diagnostic terminal may be diagnosed as a central nervous system or peripheral nervous system nystagmus according to any one of the test items of spontaneous nystagmus, primary cyanide, and occipital rotation.

In addition, if the right dix-hall is progressed, vibration is observed in the upper direction, and when the external extremity is observed to the right, it is diagnosed with right posterior annulus dysplasia, and if left dix-hall is progressed, vibration ( If the Beating is upward and the left extorsion is observed, it can be diagnosed with left posterior annulus dysplasia.

In addition, when the rolling test, which is an inspection in which the head is turned to the left or right by more than 45°, a horizontal angulation directed to the left occurs when the subject's head is turned to the left, and the horizontal angulation is geotrophc when turned to the right. , When comparing the size of the exogene, it is diagnosed that there is a stone in the right lateral semicircular canal if the right side is larger, and that there is a stone in the left lateral semicircular canal tube when the left side is larger.

In addition, in the case where the rolling test, which is an inspection in which the head is turned to the left or right by more than 45°, has an ocular to the right when turned to the left, and an angular to the left when turned to the right is agiotrophc. When comparing the size of Anjin, it can be diagnosed that if the right side is larger, there are stones in the left lateral semicircular canal, and if the left side is larger, there are stones in the right lateral semicircular canal.

As described above, the present invention extracts vibration information and torsion information through an angi and a terminal, and diagnoses peripheral nervous system and central nervous system nystagmus, horizontal and semicircular canal dysplasia or posterior canal dysplasia on the basis of this. There is an effect that can be done.
