Description

A torticometer measuring device, measuring method, and computer program that measures the degree of tilt or rotation of a user's head through human body image analysis BODY IMAGE ANALYSIS}

The present invention relates to a torticollis measuring device, measuring method, and computer program capable of measuring the degree of tilting or rotation of a user's head.

Torticism is a condition in which the neck is fixed in a tilted state. Depending on the cause, it can be divided into muscular torticollis, torticollis due to cervical deformity, torticism due to abnormalities in the nervous system, and torticism due to ophthalmic problems. Muscular torticosis, one of the most common congenital torticols, is caused by a mass or shortening of the unilateral sternocleidomastoid muscle, a neck muscle. The sternocleidomastoid muscle is located close to the skin surface, and is connected from the mastoid process behind the left and right ears to the sternum and clavicle to form a V shape at the front of the muscle neck. Although the cause of muscular torticollis is unclear, it is presumed that one of the causes is damage to the sternocleidomastoid muscle during childbirth or damage caused by posture in the uterus.

As torticollis progresses, the damaged muscle contracts and the head tilts in the direction the damaged muscle is located, and the chin tilts in the opposite direction to the direction in which the head is tilted. As this condition continues, the symmetry of the skull and face is broken, and the shoulder on the side of the damaged muscle rises asymmetrically. In addition, pediatric torticollis can cause asymmetry of not only the face, but also the spine, pelvis, etc., and visual acuity can be deteriorated.

After identifying the cause of torticollis, treatment plans are established according to the cause. In the case of muscular torticollis, one of the most common congenital torticollis, extensor exercises of the sternocleidomastoid muscle and muscle strengthening exercises are combined. Up to the first year of life, there is a possibility that the cells of the fibrous muscle can also be regenerated, so it can be corrected 80-90% with only physical therapy. However, after 1 year of age, it is difficult to expect natural muscle cell regeneration, and the fibrous part becomes relatively shorter and deteriorates. If symptoms do not improve with physical therapy, botulinum toxin injection treatment may be considered, and if conservative treatment does not improve, surgical treatment may be performed. However, in the case of patients after the age of 8 years, when the surgery is delayed, the shape of the face is deformed due to the influence of the already shortened sternocleidomastoid muscle, so there is a problem that the asymmetry of the face does not improve. Therefore, early detection and treatment through physical therapy is important.

In order to evaluate the degree of torticollis, conventionally, the degree of tilting or rotation of the head was measured by bringing a physical protractor to the child's head. During this process, children felt a sense of rejection and burden, so they toss and turn or refuse to measure, making it difficult to accurately measure the degree of torticollis.

Related prior art US Patent Publication No. WO5845638 (hereinafter abbreviated as 'prior patent') discloses a device for measuring the degree of torticollis in a patient using an actual protractor.

On the other hand, the present applicant conducted a study that can measure torticollis simply by recognizing an image of a human body without using any additional tools such as an actual protractor. Accordingly, it was confirmed that by measuring the degree of torticollis more conveniently than the prior patent, the user's objection was reduced, and the process could be performed more quickly and accurately.

US Patent Publication No. WO5845638

An object of the present invention is to provide an apparatus, method, and computer program capable of early detection and treatment of torticollis in which the head is tilted or rotated in consideration of the characteristics that occur mainly in the childhood stage.

In the case of children, unlike adults, they feel rejection or fear in the process of measuring the degree of torticollis. In consideration of this point, the present invention aims to provide an apparatus, method, and computer program that do not require a tool to be directly contacted or worn by a child so that the degree of torticism can be quickly and accurately measured while reducing the burden.

The problems to be solved by the present invention are not limited to the aforementioned problems. Other objects and advantages of the present invention will be more clearly understood by the following description.

In order to achieve the above object, the present invention, a face recognition unit for recognizing the user's face to generate face data; an extractor configured to receive the face data and extract an eye region from the face data; a reference line generator generating a reference line passing through both eyes in the extracted eye region; and an angle measuring unit for generating a horizontal line that is parallel to the ground and in contact with the reference line, and measures an angle between the horizontal line and the reference line.

Preferably, the reference line generated by the reference line generator may pass through the central portion of each vertical length of the two eyes.

Preferably, the angle measuring unit may generate a protractor image in which the horizontal line is displayed.

Preferably, the face recognition unit, characterized in that the size of the user's face is recognized differently according to the distance from the user, and further comprises a distance determination unit for measuring the distance to the user through the recognized difference in the size of the face can

Preferably, the angle measuring unit generates a protractor image, and the size of the protractor image may be different according to the distance to the user measured by the distance determining unit.

Preferably, it may further include a database that stores the angle measured by the angle measurement unit for each user and tracks the change process of the tilted or rotated degree of the user's head.

Preferably, the angle measurement unit may further include a guide for providing instructions according to the angle to the user.

In addition, in order to achieve the above object, the present invention, the steps of recognizing the user's face and measuring the distance to the user according to the size of the face; generating facial data of the user; receiving the face data and extracting an eye region from the face data; generating a reference line for generating a reference line passing through both eyes in the extracted eye region; generating a horizontal line that is level with the ground and is in contact with the reference line; generating a protractor image based on an intersection of the reference line and the horizontal line; measuring an angle between the reference line and the horizontal line through the protractor image; and storing the measured angle in chronological order for each user, and providing instructions according to the measured angle.

Preferably, the generating of the protractor image may generate the protractor image of a different size according to the distance to the user measured in the step of measuring the distance to the user.

In addition, in order to achieve the above object, the present invention is coupled with a smart phone, tablet, notebook, or computer having an input means for inputting data and a processing means for processing the input data to recognize the user's face, thereby recognizing the size of the face measuring the distance to the user according to; generating facial data of the user; receiving the face data and extracting an eye region from the face data; generating a reference line for generating a reference line passing through both eyes in the extracted eye region; generating a horizontal line that is level with the ground and is in contact with the reference line; generating a protractor image based on an intersection of the reference line and the horizontal line; measuring an angle between the reference line and the horizontal line through the protractor image; and storing the measured angle in chronological order for each user, and providing instructions according to the measured angle.

According to the present invention, without using any actual physical protractor or tool, it is possible to generate and measure a virtual reference line or a virtual protractor in a tilt measurement device or program. Therefore, since no contact or stimulation is applied to the subject (pediatric patient) to be measured for torticollis, negative emotions such as rejection and anxiety may not occur when measuring torticollis degree. Because pediatric patients do not feel rejection or anxiety, the degree of torticol can be measured more quickly and easily.

In addition, according to the present invention, since the medical person who measures torticollis does not need to have an actual protractor or a physical tool, it is spatially free, economical in terms of cost, and it is possible to measure more conveniently because the movement of the pediatric patient is minimized.

According to the present invention, since each pediatric patient's head, more specifically, the eye area or the ear area of the face is individually recognized and measured, individual characteristics of the patient's body can be taken into account, thereby accurately measuring the degree of torticollis.

In addition, a feature in which the distance between the pediatric patient and the torticollis measuring device varies can be distinguished through the size of the recognized image. Therefore, it is possible to accurately measure the degree of torticollis by generating different sizes of the protractor images according to the distance.

According to the present invention, since a virtual protractor image is generated over the user's head, it is possible to easily check whether the marker or the protractor image is leveled, and there is an advantage in that the degree of torticism can be intuitively grasped. Double-check is possible because the angle measured intuitively through the protractor image and the oblique angle measured by the torticollis measuring device of the present invention can be compared. In addition, since the degree of torticollis can be visualized and presented from the protractor image, it is possible to explain it more easily and effectively to the caregiver or patient.

In addition, according to the present invention, by continuously storing data on the degree of torticism according to the measurement time point, the change process can be comparatively analyzed, and there is an advantage that a treatment guide corresponding to the degree of torticism can be provided to the user according to the degree of torticism.

Hereinafter, the present invention will be described in detail with reference to the contents described in the accompanying drawings. However, the present invention is not limited or limited by the exemplary embodiments. The same reference numerals provided in the respective drawings indicate members that perform substantially the same functions.

Objects and effects of the present invention can be naturally understood or more clearly understood by the following description, and the objects and effects of the present invention are not limited only by the following description. In addition, in describing the present invention, if it is determined that a detailed description of a known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

1 shows a configuration diagram of a torticollis measurement apparatus 1 according to an embodiment of the present invention. The detailed configuration of the torticollis measuring device 1 is defined for convenience of explanation, and is not physically separated and may be implemented in an integrated manner.

As for the torticollis, the user's head (center of the head) does not coincide with the sagittal plane of the human body, and the first torticollis in which the head is tilted in the shoulder direction and the second torticollis in which the head is rotated left and right from the coronal plane of the human body may be considered. The torticollis measurement apparatus 1 may evaluate the tilted or rotated first or second torticollis by synthesizing images captured by the user during angle measurement. The torticollis measuring device 1 may provide an appropriate management guide according to the degree to which torticollis has progressed.

The tilt measurement device 1 includes a face recognition unit 11 , an extraction unit 13 , a distance determination unit 14 , a baseline generation unit 15 , an angle measurement unit 17 , a database 18 , and a guide unit 19 . ) may be included.

The face recognition unit 11 may generate face data by recognizing the user's face. The face recognition unit 11 may recognize the size of the user's face differently according to the distance from the user.

The extractor 13 may receive the face data and extract an eye region from the face data.

The distance determining unit 14 may determine the distance to the user through the difference in the size of the face recognized by the face recognition unit 11 . The distance determining unit 14 compares the face size of the user recognized by the face recognition unit 11 with the face size according to the distance between the torticollis measuring device 1 and the user pre-stored in the database 18, and the user determines the torticollis measuring device. The distance from (1) can be determined. According to the distance between the tilt measuring device 1 and the user measured by the distance determining unit 14, the angle measuring unit 17 generates different sizes of the horizontal line 171, the vertical line 173, and the protractor image 175. can

The reference line generator 15 may generate an eyeball reference line 151 and an orthogonal reference line 153 . The eyeball reference line 151 and the orthogonal reference line 153 may be generated as virtual images in the torticollis measurement apparatus 1 and may have an orthogonal relationship to each other.

The eyeball reference line 151 may be generated to pass through both eyes of the eye region extracted by the extraction unit 13 . The eyeball reference line 151 may pass through two points having similar positional characteristics of the two eyes. That is, the eyeball reference line 151 may pass through both upper ends, both lower ends, or both central portions at the point where the length of each eye in the vertical direction is longest.

The angle measuring unit 17 may generate a horizontal line 171 and a vertical line 173 . The horizontal line 171 and the vertical line 173 may be generated as virtual images in the oblique angle measuring device 1 . The horizontal line 171 may be parallel to the ground, and the vertical line 173 may be generated to be perpendicular to the horizontal line 171 . Since the horizontal line 171 and the vertical line 173 are generated according to the geomagnetic field, their directions do not change arbitrarily, and thus can be a reference for measuring the oblique tilt.

The horizontal line 171 may come in contact with the eyeball reference line 151 to generate one intersection, and the vertical line 173 may come in contact with the orthogonal reference line 153 to generate one intersection. The angle measuring unit 17 may measure an angle between the horizontal line 171 and the eyeball reference line 151 or an angle between the vertical line 173 and the orthogonal reference line 153 . That is, the measured angle may be an angle from the horizontal line 171 to the eyeball reference line 151 or an angle from the vertical line 173 to the orthogonal reference line 153 .

The angle measuring unit 17 may generate a protractor image 175 , and the protractor image 175 may include a horizontal line 171 and a vertical line 173 . The protractor image 175 may be generated as a virtual image in the torticollis measuring device 1 . The point of intersection of the horizontal line 171 and the vertical line 173 and the origin of the intersection of 0 degrees and 90 degrees of the protractor image 175 may coincide. 0 degrees or 90 degrees of protractor image 175 may coincide with horizontal line 171 or vertical line 173 . The angle measuring unit 17 may measure the angle at which the eyeball reference line 151 or the orthogonal reference line 153 is tilted from the horizontal line 171 and the eyeball reference line 151 by using the protractor image 175 .

The angle measuring unit 17 may generate protractor images of different sizes according to the distance to the user measured by the distance determining unit 14 . Hereinafter, it will be described in detail with reference to FIG. 4 .

The database 18 may store information about the size of the face according to age, gender, and the like. The pre-stored size of the face according to age, gender, etc. may be used by the distance determining unit 14 to determine the distance to the torticollis measuring device 1 through the size of the user's face. The database 18 may categorize and store the distance between the torticollis measuring device 1 and the user and the size of the face through the determination result of the distance determination unit 14 . The database 18 may store the angle measured by the angle measurement unit 17 for each user and track the change process of the degree of tilting or rotation of the user's head.

The guide unit 19 may provide the user with instructions according to the angle measured by the angle measurement unit 17 . The guide unit 19 may display instructions according to the degree to which the user's head is tilted or rotated on the screen of the torticollis measuring device 1 . Since the torticollis measuring device 1 may be connected to a user terminal such as a smartphone, tablet, notebook or computer by short-range wireless communication (such as Bluetooth or NFC), the guide unit 19 may transmit instructions to the user terminal.

FIG. 2 is a flowchart illustrating a process in which a torticollis angle is measured by recognizing a human body image by the torticollis measuring apparatus 1 according to an embodiment of the present invention. In more detail, it is a method for recognizing and extracting the user's face and eye regions by the face recognition unit 11 and the extraction unit 13 .

In recognizing the face and eye regions as an embodiment of the present invention, a Haar feature-based cascade classifier may be used. In order to train through the Haar feature-based multi-level classifier, images with and without multiple faces can be basically used. By using Harr features (Edge, Line, Center-surround features), a grayscale value (color intensity) difference between specific internal regions can be calculated, and this difference can be learned as a feature of each region. Differences in grayscale values between specific inner regions may be characterized, for example, in that the eye regions are darker than the nose, cheeks, or brows.

The Adaboost algorithm can be used to select a main feature among numerous calculated features. In order to reduce the amount of computation, instead of using all the features as a single classifier input, an input value input to the classifier of the corresponding stage can be generated by configuring the classifiers of several stages individually to classify and group the features. For example, in the first step, only the eyebrows and nose, which are very important vertical/horizontal features in face recognition, can be detected.

The region determined as the face or eye region is a case in which the features calculated in the corresponding region have passed through the classifiers of all stages. If the feature calculated in the corresponding region does not pass the classifier of a specific stage, the region may be excluded from the face or eye region.

3 is a view showing the angle of the head tilted (first torticollis) measured by photographing the user's face and recognizing both eyes in the torticol measurement apparatus 1 according to an embodiment of the present invention.

The torticollis measuring apparatus 1 may photograph the user's face to generate the user's facial data, and then display the user's face on the torticollis measuring device 1 . Alternatively, the torticol measurement apparatus 1 may extract an eye area from the user's face data so that only the eye area is displayed.

The torticollis measurement apparatus 1 may display the eyeball reference line 151 generated by the reference line generator 15 or an orthogonal reference line 153 orthogonal to the eyeball reference line 151 over the user's face or eye region. The eyeball reference line 151 may be generated to pass through a point where the positional features of the two eyes are similar in the eye region.

3 shows the eye area in a dotted line on the screen on which the user's face is displayed, which is enlarged to the right. Referring to the enlarged eye area, the eyeball reference line 151 may be formed through the center of the point where the vertical length of both eyes is longest.

The orthogonal reference line 153 may be generated to be orthogonal to the eyeball reference line 151 . The orthogonal reference line 153 may pass through the center of each point of the two eyes as a reference for generating the eyeball reference line 151 . The point of intersection of the eyeball reference line 151 and the orthogonal reference line 153 may be located at the center between the two eyes, more specifically, at the center between the respective points of the two eyes as a reference for generating the eyeball reference line 151 .

Referring to FIG. 3 , the torticol measurement device 1 may display a horizontal line 171 horizontal to the ground passing through the intersection of the eyeball reference line 151 and the orthogonal reference line 153 , and is orthogonal to the horizontal line 171 and upper A vertical line 173 passing through the intersection of three straight lines (the eyeball reference line 151 , the orthogonal reference line 153 , and the horizontal line 171 ) may be displayed. Also, the torticollis measuring device 1 may display the protractor image 175 on the user's face or eye region image.

The reference point (0 degree or 90 degree) of the protractor image 175, the horizontal line 171, and the vertical line 173 may coincide. Referring to FIG. 3 , two points marked 90 at both ends and the horizontal line 171 may coincide with each other by a predetermined distance from the center point of the protractor image 175 to the left and right. In addition, the vertical line 173 may coincide with a point marked 0 by being spaced upward by a predetermined distance from the center point of the protractor image 175 .

When the eyeball reference line 151 and the orthogonal reference line 153 and the center points of the protractor image 175 all coincide, a horizontal line 171 and a vertical line 173 may be displayed on the protractor image 175 . The eyeball reference line 151, the orthogonal reference line 153, the horizontal line 171, the vertical line 173, and the protractor image 175) expressed as a virtual image inside the torticollis measuring device 1) It is defined to be created and is not physically separated and may be created and expressed at one time.

The torticol measurement apparatus 1 can measure the degree of torticollis using the protractor image 175 generated by the angle measuring unit 17, or the eyeball reference line 151, orthogonal without using the protractor image 175 An angle between the reference line 153 , the horizontal line 171 , and the vertical line 173 may be measured.

Referring to FIG. 3 , since the eyeball reference line 151 and the orthogonal reference line 153 are orthogonal to each other, and the horizontal line 171 and the vertical line 173 are also orthogonal to each other, the angle between the eyeball reference line 151 and the horizontal line 171 is An angle between the orthogonal reference line 153 and the horizontal line 171 may coincide. Therefore, only the angle of either part can be measured. The measured angle may be stored in the database 18 .

The eyeball reference line 151 and the orthogonal reference line 153 may have different positions or directions depending on the degree to which the user's head is tilted or rotated, but a horizontal line 171 , a vertical line 173 , and a protractor image 175 including the same ) only changes in size, but the generated position and direction may be constant.

Figure 4 is a view of measuring the rotation angle of the head by recognizing the two ears by photographing the upper surface of the user's head in the torticollis measuring apparatus 1 according to another embodiment of the present invention. The present invention can measure not only the first torticollis in which the head is tilted in the shoulder direction by photographing the user's face, but also the second torticoscopy in which the maximum left and right rotational angles of the head are limited by photographing the user's head. In the case of measuring the second oblique angle, the standard for measuring the angle may be an ear or a coil. The position and shape of the ears or nose, which are the criteria for measuring torticollis, are learned by machine learning or deep learning methods from a large number of head image data on the upper surface of the head and stored in the database 18, or torticol measurement is performed as described below. The device 1 may measure the degree of torticollis by directly recognizing it from the head image data.

4 illustrates a case where the standard for angle measurement is the ear. Referring to FIG. 4 , the torticollis measuring apparatus 1 may display a view from above by photographing an upper surface of the user's head. In this case, the displayed image may include the upper surface of the head, both ears next to the head, the nose, and both shoulders.

First, the torticollis measuring device 1 recognizes the upper surface of the head to generate head image data, expresses the generated head image data in a two-dimensional coordinate system, and calculates the weight of each coordinate to determine the centroid of the head image. can be calculated.

Thereafter, as shown in FIG. 4 , when the angle measurement standard is the ear, the torticollis measurement apparatus 1 may extract the ear region from the head image data. Among the extracted ear regions, the part having similar positional features, for example, when the head is viewed from above, the point closest to the face (1) among the ear regions, the point closest to the back of the ear region (2) or (1) The midpoint (3) between the point (2) and the point (2) can be set at each ear respectively. The ear reference line 151 may be formed to pass through each point of both ears having similar positional characteristics.

4 is an enlarged view of the center of the head image and the ear region on the right side of the screen on which the upper surface of the user's head is displayed, and the left ear region is enlarged again. Referring to the enlarged ear region, the ear reference line 151 may be formed through the midpoint (point (3) described above) of both ears.

Orthogonal baselines 153 may be created between the two ears on either side. It may be generated to be perpendicular to the ear reference line 151 . The intersection of the orthogonal reference line 153 and the ear reference line 151 may be a centroid of the head image. At this time, as shown in FIG. 4 , the orthogonal reference line 153 extending long beyond the user's head may pass through the user's nose while passing through the middle point between the two ears. That is, the longitudinal direction in which the orthogonal reference line 153 extends may be the same as the direction indicated by the tip of the user's nose.

On the other hand, as another embodiment of measuring the second oblique mirror in the present invention, the reference of the angle measurement may be a coil. When the angle measurement standard is a coin, the nose region may be recognized from the head image data using the position and shape data of the nose pre-stored in the database 18 . The torticol measurement apparatus 1 may calculate a centroid from the head image data, and may generate a virtual vertical line or a horizontal line passing through the centroid with the centroid as the center. By connecting the generated vertical/horizontal lines and the recognized nose area, the degree of the second torticol can be measured.

3 (first torticollis) and 4 (second torticollis) have different reference areas (or reference points) for generating the reference line 151 for measuring torticollis, but the method of measuring torticollis by recognizing a human body image is a diagram 1 to 3 may proceed as described above.

5 is an embodiment of the present invention, the torticol measurement device (1) shows a state of measuring the degree of torticism in children by generating a protractor image 175 of different sizes according to the distance of the torticol measurement device (1) and the user. In more detail, Fig. 5a is a case where the distance between the user and the torticollis measuring device 1 is close (a), and Fig. 5b is a case where the distance between the user and the torticollis measuring device 1 is long (b) (a<b).

Referring to FIG. 5A , when the user and the torticollis measuring device 1 are close, the face recognition unit 11 recognizes a relatively large size of the user's face, so the torticollis measuring device 1 reduces the protractor image 175 By implementing it, it can be easy to measure the angle at which the user's head is tilted or rotated.

On the other hand, referring to FIG. 5B , when the user and the torticollis measuring device 1 are far away, the marker recognition unit 11 recognizes a relatively small size of the user's face, so the torticollis measuring device 1 is a protractor image 175 It is possible to easily measure the angle by implementing a larger .

In addition, the present invention may be a torticol measurement method performed by the torticollis measurement apparatus 1 as another embodiment of the present invention.
