Description

The present invention relates to a scapula position calculation device and a scapula position calculation method.

It is empirically known that the posture of the human body changes depending on various mental and physical conditions. For example, when he is depressed, his appearance changes, such as dropping his shoulders. In addition, the usefulness of yoga for post-traumatic stress syndrome (PTSD) and the like has been reported.

On the other hand, techniques exist for measuring the position of the spine and scapula. For example, Japanese Patent Publication No. 2015-535451 (Patent Document 1) discloses a method for determining the spatial position and orientation of vertebrae in the spinal column using X-ray images. In this method, a single X-ray image of a portion of the spinal column is taken, while surface data of a portion of the back are recorded by optical methods, positions of elements of the bony structure are determined by the X-ray image, and surface Determining the location of a characteristic element in the data, determining an anatomical fixation point, superimposing one X-ray image and the surface data taken with the anatomical fixation point, A three-dimensional model is computed from elements of the bone structure from the line image. The three-dimensional model includes the position and orientation of the vertebrae, spinal column and spinous process development, and spinous process and spinal development shifts. This allows accurate measurement of the spatial position and orientation of the vertebrae within the spinal column.

In addition, Japanese Utility Model Registration No. 3207832 (Patent Document 2) discloses a posture checking tool composed of a translucent base material. In this posture testing tool, the base material is provided with a measuring part consisting of a design showing the contour of the human body in a state where the body is not distorted, the inner part of the contour of the human body is translucent, and the part inside the contour of the body is translucent. The distortion of the subject's body is inspected with the outline of the human body design of the measurement unit superimposed on the outline. This makes it possible for even a person who does not have a deep knowledge of posture distortion inspection to easily inspect posture distortion.

On the other hand, Japanese Patent Application Laid-Open No. 2015-205169 (Patent Document 3), for which the present applicant has already filed and obtained a patent, discloses a scapula position measuring instrument and a scapula position measuring method. This instrument includes a main body portion extending in the height direction, a bar portion extending in the right or left direction of the main body portion, the main body portion being arranged at a predetermined position along the spinal column, and the bar portion is displaced in the main body so as to match the height position of a predetermined portion of the right shoulder blade or left shoulder blade, and the position of the predetermined portion of the right shoulder blade or left shoulder blade with respect to the bar portion is measured to obtain the right shoulder blade or left shoulder. By measuring the horizontal position of the blade and measuring the position of the bar relative to the main body, the height of the right or left scapula is measured. As a result, it is possible to objectively measure the effectiveness of treatment for stiff shoulders and poor posture caused by scapular malposition.

Japanese Patent Publication No. 2015-535451 Utility Model Registration No. 3207832 JP 2015-205169 A

At present, there is almost no research on various mental disorders such as PTSD, psychological conditions/psychological load, and postural factors including the position of the scapula.

Here, as described above, although there is a technique for measuring the position of the spine and scapula, the technique described in Patent Document 1 requires equipment for taking X-ray images, so that the position of the spine and the position of the scapula can be easily measured. There is a problem that the orientation cannot be measured. In addition, the technique described in Patent Document 2 has a problem that the positions and orientations of the scapula and spine of the subject cannot be specifically measured. Furthermore, in the technique described in Patent Document 3, it is necessary for the measurer to directly place the bar on the position of the subject's right or left scapula, and it takes time and effort to measure the position of the subject's scapula. I have a problem. In addition, since the subject is in close contact with the subject, there is a problem that the risk of contact infection with an infectious disease such as the novel coronavirus increases. Furthermore, in the techniques described in Patent Documents 1 to 3, the position of the scapula cannot be measured three-dimensionally. There is a difficult issue.

On the other hand, there is growing interest in the relationship between mental disorders, psychological conditions, and psychological load, and postural factors, and postural factors are closely related to the position of the left and right shoulder blades. Therefore, there is a demand for an apparatus and method that can easily measure the positions of the left and right scapulae of a subject.

In addition, with the recent spread of mobile terminal devices (smartphones and tablets), users often continue to use mobile terminal devices with their heads down. Here, it has been found that if the user continues to use the mobile device while looking down, the neck that supports the head will be heavily burdened, the neck curve will be lost, and the neck bone will gradually straighten (straightening). neck). A straight neck is caused by a user's continued use of a desktop terminal device for a long time. Such a straight neck causes stiffness and pain in the neck, shoulders, back, lower back, etc. In severe cases, pain, numbness, deformation of the spine, hernia, cold hands and feet, headache, eye strain, nausea, and dizziness. , Chronic dullness, poor blood circulation, etc. On the other hand, the straight neck is closely related to the position of the left and right scapulae, and measuring the position of the left and right scapulas is of great significance in verifying the straight neck.

Accordingly, the present invention has been made to solve the above problems, and is a scapula position calculation device and a scapula position calculation method capable of three-dimensionally calculating the position of the scapula of a subject without contact. intended to provide

A first acquisition control unit acquires a spine point indicating a part of the spine from the three-dimensional point cloud of the surface of the back. A second acquisition control unit indicates a left scapula point indicating a part of the left scapula on the back of the subject and a part of the right scapula on the back of the subject among the three-dimensional point cloud of the surface of the back.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. It should be noted that the following embodiment is an example that embodies the present invention, and is not intended to limit the technical scope of the present invention.

The present inventor has been conducting research for many years on the relationship between mental disorders, psychological situations, and psychological loads, the positions of the left and right shoulder blades, and the positions and postures of the left and right shoulder blades. (JP 2015-205169) scapula position measurement instrument and scapula position measurement method are used for business development, but this time, by using a three-dimensional point cloud measurement instrument, unexpectedly, the subject's scapula Since the position of was able to be calculated three-dimensionally, the present invention was completed based on the examples described later.

That is, the scapula position calculation device 1 according to the present invention includes a three-dimensional point group measuring instrument 10 and a terminal device 11, as shown in FIG.

The three-dimensional point cloud measuring instrument 10 is not particularly limited as long as it is an instrument that can measure a three-dimensional point cloud (a plurality of three-dimensional coordinate values) on the surface of the object without contact. A camera (photographing device) that measures a 3D point cloud on the surface of an object by photographing a calibration plate, or a laser that irradiates the surface of the object and uses the reflected light to obtain a 3D image of the surface of the object. A three-dimensional laser scanner that measures a dimensional point group can be used. Here, the camera may be built in the mobile terminal device, or may be a depth camera capable of capturing depth (depth distance) values.

In addition, for example, by providing a reflective sticker on the surface of the object and photographing the surface of the object including the reflective sticker at different angles with a plurality of cameras, the 3D point cloud of the reflective sticker on the surface of the object can be obtained. A tracking system to measure (equivalent to so-called motion capture), an infrared camera or object that detects the temperature of the surface of the object, calculates the perspective of the surface of the object, and measures the 3D point cloud on the surface of the object Examples include a dot projector that irradiates a surface of an object with a specific light irradiation pattern and uses the reflected light to measure a three-dimensional point group on the surface of the object.

The configuration of the control unit of the three-dimensional point cloud measuring instrument 10 is not particularly limited. After measuring the three-dimensional point cloud on the surface of the subject's back with the instrument 10, the terminal device 11 may perform calculations and output the measured values of the three-dimensional point cloud. In addition, a control unit is incorporated in the three-dimensional point cloud measuring instrument 10, and when the three-dimensional point cloud of the back surface of the subject is measured with the three-dimensional point cloud measuring instrument 10, the internal control unit performs calculations, Only the measured values of the dimensional point cloud may be output.

The terminal device 11 is a commonly used computer, and includes, for example, a mobile terminal device with a touch panel, a tablet terminal device, a wearable terminal device, and a desktop terminal device. The terminal device 11 includes a storage unit, an input unit, and an output unit. The input unit is, for example, a keyboard, mouse, touch panel, etc., and the output unit is, for example, a liquid crystal display.

The terminal device 11 incorporates a CPU, ROM, RAM, etc. (not shown), and the CPU, for example, uses the RAM as a work area and executes programs stored in the ROM, etc. FIG. Each control unit, which will be described later, also implements the function of each control unit by executing the program by the CPU. Note that the program may be software or an application that can be obtained from a server such as a cloud via a network.

Next, a configuration and an execution procedure according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. First, the measurer receives a request from the subject S, activates the terminal device 11, asks the subject S to take a predetermined posture (for example, a normal posture), and measures the three-dimensional point cloud on the back of the subject S. The instrument 10 is installed and a measurement key is input to the terminal device 11 . Then, the measurement control unit 101 of the terminal device 11 uses the three-dimensional point cloud measuring instrument 10 to measure the three-dimensional point cloud of the back surface of the subject S in a predetermined posture (FIG. 2: S101).

The measurement method of the measurement control unit 101 is appropriately changed according to the type of the three-dimensional point cloud measuring instrument 10 . For example, when a camera using a calibration plate is used as the three-dimensional point cloud measuring instrument 10, as shown in FIG. The back of the subject S, including the calibration plate 10a, is photographed from a first direction by the camera 10b. The back of the subject S including the calibration plate 10a is photographed from two directions.

Then, two captured images captured in the first direction and the second direction are sent from the camera 10b to the terminal device 11, and the measurement control unit 101 of the terminal device 11 performs two images as shown in FIG. A three-dimensional point group of the back surface of the subject S can be obtained based on the captured images, with reference to the calibration plate 10a.

Although the configuration of the calibration plate 10a is not particularly limited, for example, a configuration in which circular marks are provided at each of the four corners of a rectangular shape can be mentioned. By photographing the four marks on the calibration plate 10a in two different directions and using the two photographed images and the relative positional information of the four marks on the calibration plate 10a, a specific camera can be obtained. A three-dimensional point cloud of the four marks on the calibration plate 10a can be acquired with reference to the position, and a three-dimensional point cloud of the back surface of the subject S placed on the calibration plate 10a can be calculated. In this state, for example, when the measurer designates an arbitrary point on the surface of the back of the subject S in the photographed image, the three-dimensional coordinate values of the designated point can be obtained.

On the other hand, when the three-dimensional laser scanner is used as the three-dimensional point group measuring instrument 10, as shown in FIG. The subject S is made to stand in the facing state, and the back of the subject S is scanned by the three-dimensional laser scanner 10c.

Then, the three-dimensional point group scanned by the three-dimensional laser scanner is sent to the terminal device 11, and the measurement control unit 101 of the terminal device 11, as shown in FIG. A three-dimensional point cloud of the back surface of the subject S can be obtained with reference to a specific position of the scanner.

In addition, as another method, using images and videos of the surface of the back of the subject S photographed from two different directions with a camera, based on changes in saturation, brightness, brightness, hue, etc. , the three-dimensional point cloud of the back surface of the subject S may be measured, or the three-dimensional point cloud of the back surface of the subject S may be measured from the depth camera as described above.

Now, when the measurement control unit 101 completes the measurement, next, the first acquisition control unit 102 of the terminal device 12 indicates a part of the spine of the back of the subject S from the three-dimensional point cloud of the surface of the back. A spinal point is acquired (FIG. 2: S102).

The acquisition method of the first acquisition control unit 102 is not particularly limited. For example, as shown in FIG. 5, generally, 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae are arranged downward from the head in the center of the human back. Left and right shoulder blades are arranged on the left and right. The cervical, thoracic and lumbar vertebrae are referred to as the spine. As the spine point, any one of the cervical spine point, the thoracic spine point, the lumbar spine point, or a combination thereof can be adopted. A cervical point is any, between, or a combination of the 1st to 7th cervical vertebrae, and a thoracic point is any, between, or a combination of the 1st to 12th thoracic vertebrae. A combination, where the lumbar point is any, between, or a combination of 1st to 5th lumbar vertebrae. In the following description, for example, one cervical vertebrae point and one thoracic vertebrae point will be described as examples of spinal points.

Here, of the seven cervical vertebrae, the seventh cervical vertebrae C7, which is the seventh from the head, has a spinous process C7a that protrudes the most to the outside compared to other cervical vertebrae. The position protrudes from the surface of the back and can be viewed from the outside.

Therefore, when the measurer designates the protrusion C7a protruding in the upper center of the back as the spinous process C7a of the seventh cervical vertebrae C7 in the three-dimensional point cloud of the back surface of the subject S, the first acquisition control unit 102 acquires the three-dimensional coordinate value of this protrusion C7a as a cervical vertebrae point C7 indicating a part of the cervical vertebrae in response to the measurement person's designation.

Next, of the 12 thoracic vertebrae, the first thoracic vertebrae T1, which is the first from the head, is closest to the seventh cervical vertebrae C7 compared to other thoracic vertebrae, and has a spinous process T1a protruding to the outside. , The position of the spinous process T1a of the first thoracic vertebra T1 protrudes from the surface of the back and can be visually observed from the outside.

Therefore, when the measurer designates the projection T1a closest to the cervical vertebra point of the seventh cervical vertebrae C7 as the spinous process T1a of the first thoracic vertebrae T1 in the three-dimensional point cloud of the back surface of the subject S, the first Acquisition control unit 102 acquires the three-dimensional coordinate value of this projection T1a as a thoracic vertebra point T1 indicating a part of the thoracic vertebrae in response to the measurement person's designation.

In this way, the measurer designates the spinous process C7a of the seventh cervical vertebrae C7 and the spinous process T1a of the first thoracic vertebrae T1 using the protrusions on the surface of the back of the subject S as marks, thereby performing the first acquisition. The control unit 102 acquires the three-dimensional coordinate values of the cervical vertebrae point C7 and the thoracic vertebrae point T1. Thereby, the measurer can acquire the cervical vertebrae point C7 and the thoracic vertebrae point T1 for calculating the positions of the left and right scapulae of the subject S without touching the subject S.

Here, since both the cervical vertebrae point C7 and the thoracic vertebrae point T1 are located on a straight line of the spine from the head to the chest of the subject S, these points are the reference of the positions of the right and left shoulder blades of the subject S. can be a position.

In the above description, the measurement person designates the spinous process C7a of the seventh cervical vertebrae C7 and the spinous process T1a of the first thoracic vertebrae T1, so that the cervical vertebrae point C7 and the thoracic vertebrae point T1 are acquired as vertebrae points. However, spinous processes of other vertebrae may be specified. For example, the measurer may acquire a lumbar vertebrae point indicating a part of the lumbar vertebrae as the vertebrae point. As a method for the measurer to specify the lumbar vertebrae, for example, using the Jacoby line of the line connecting the highest points of the left and right iliac crests, the 4th lumbar vertebrae, the 5th lumbar vertebrae, or the 4th lumbar vertebrae and the 4th lumbar vertebrae It is possible to specify between 5 lumbar vertebrae.

Alternatively, other methods may be used. For example, when the three-dimensional point cloud measuring instrument 10 includes the camera 10b, a black shadow is projected on the projections of the back of the subject S in the image captured by the camera 10b. For example, the position of the spinous process C7a of the seventh cervical vertebrae C7 or the spinous process T1a of the first thoracic vertebrae T1 may be specified, and the specified points may be acquired. In this case, the position of the protrusion may be specified manually by the operator, or software that measures the position of the protrusion based on changes in features such as shadow, saturation, brightness, lightness, and hue of the protrusion. may be created and software may be used to automatically identify the position of the protrusion.

The more the feature points of the spine of the subject S, the more accurately the position of the spine of the subject S can be calculated.

Now, when the first acquisition control unit 102 completes the acquisition, next, the second acquisition control unit 103 of the terminal device 12 controls the left scapula point indicating a part of the left scapula on the back of the subject S, the subject S A right scapula point indicating a part of the right scapula on the back of the user is obtained (Fig. 2: S103).

The acquisition method of the second acquisition control unit 103 is not particularly limited. For example, as shown in FIG. 5, generally, on the surface of the back of the subject S, the left scapular spine protruding outward is present near the upper part of the left scapula, and the right shoulder The scapula also has an externally projecting right scapular spine near the top. The positions of the left and right scapular spines protrude from the surface of the back and can be visually observed from the outside.

Therefore, when the measurer designates the projections A and B projecting to the left and right above the back from the three-dimensional point cloud of the back surface of the subject S as the left and right scapular spines, the second acquisition The control unit 103, in response to the user's designation, converts the three-dimensional coordinate values of these projections A and B into a left suprascapular point A indicating a part of the upper part of the left scapula and a point A of the upper part of the right scapula. It is obtained as a point B on the right scapula that indicates the buttocks.

In this way, in the same manner as described above, the measurer designates the projections A and B of the left and right scapular spines using the projections on the surface of the back of the subject S as a mark, thereby performing the second acquisition control. Since the unit 103 can acquire the three-dimensional coordinate values of the left suprascapular point A and the right suprascapular point B, the measurer can determine the positions of the left and right shoulder blades of the subject S without touching the subject S. It is possible to obtain the left scapula point A and the right scapula point B for calculating .

Here, since the left suprascapular point A and the right suprascapular point B are characteristic points of the left and right scapulae of the subject S, the above-described cervical vertebrae point C7 and thoracic vertebrae point T1 as vertebrae points can be compared. , it is possible to confirm the inclination and deviation of the positions of the left and right scapulae of the subject S.

Here, instead of the left suprascapular point A and the right suprascapular point B, other characteristic points of the left and right scapulae of the subject S may be acquired. For example, as shown in FIG. 5, in addition to the left and right scapular spines, the left and right lower corners of the left and right shoulder blades can be mentioned as positions that can be recognized from the outside. Specifically, in the vicinity of the lower part of the left scapula, there is a left lower angle that protrudes outward. There is a lower angle of The positions of the left and right lower corners protrude from the surface of the back and can be visually observed from the outside in the same manner as described above.

Therefore, when the measurer designates the protrusions C and D projecting to the left and right below the back in the three-dimensional point cloud of the back surface of the subject S as the left and right lower corners, the second acquisition control unit 103 receives the specification of the measurer and converts the three-dimensional coordinate values of these protrusions C and D into the left scapula point C indicating the lower part of the left scapula and the lower part of the right scapula. It may be acquired as the right scapula lower point D shown.

In this way, instead of the left scapula top point A and the right scapula top point B, the left scapula bottom point C and the right scapula bottom point D may be acquired, or all of these points may be used. good.

Also, instead of the left upper scapula point A, the right upper scapula point B, the lower left scapula point C, and the lower right scapula point D, other characteristic points of the left and right scapulae of the subject S may be acquired. . For example, as shown in FIG. 5, the left and right shoulder blades can be recognized from the outside at the left and right lower corners as well as the left and right acromions. Specifically, in the left scapula, near the upper left, there is a left acromion that protrudes outward. A prominent right acromion is present. The positions of the left and right acromions project from the surface of the back and can be visually observed from the outside in the same manner as described above.

Therefore, when the measurer designates the projections E and F projecting to the left and right above the back from the three-dimensional point cloud of the back surface of the subject S as the left and right acromions, the second acquisition control The unit 103, in response to the measurement person's designation, converts the three-dimensional coordinate values of these projections E and F into a left scapula extrinsic point E indicating a portion of the outside of the left scapula and a portion of the outside of the right scapula. may be acquired as a right scapula extra-point F indicating .

In this way, instead of the left scapula top point A, the right scapula top point B, the left scapula bottom point C, and the right scapula bottom point D, the left scapula outside point E and the right scapula outside point F are acquired. or all of these points may be adopted. The positions of the left and right shoulder blades of the subject S can be calculated with higher accuracy as the feature points of the right and left shoulder blades of the subject S increase. Further, the accuracy of the positions of the right and left shoulder blades of the subject S can be further improved as the number of spinal points and left and right shoulder blade points increases.

Now, when the second acquisition control unit 103 completes the acquisition, the calculation control unit 104 of the terminal device 12 calculates the vertebral points (for example, the cervical vertebrae point C7 and the thoracic vertebrae point T1) and the left scapula points (for example, the left scapula point). Point A) and the right scapula point (for example, right scapula point B), the distance of the line connecting any two points, and the angle between the two lines connecting any three points By calculating, the positions of the right and left shoulder blades of the subject S are calculated (FIG. 2: S104).

The calculation method of the calculation control unit 104 is not particularly limited. For example, when the three-dimensional coordinate values of four points of the cervical vertebrae point C7, the thoracic vertebrae point T1, the left upper scapula point A, and the right upper scapula point B are acquired, a three-dimensional point group is obtained as shown in FIG. 6A. In the xyz coordinate system of the three-dimensional space for representation, the cervical vertebrae point C7, the thoracic vertebrae point T1, the left suprascapular point A, and the right suprascapular point B are plotted, respectively, and the four points are connected by lines. , a model of the positions of the right and left shoulder blades of the subject S (referred to as a shoulder blade model) is created.

In this manner, the calculation control unit 104 calculates the distance between two points and the angle between three points, so that the positions of the right and left shoulder blades of the subject S can be numerically grasped. Then, the calculation control unit 104 displays the created scapula model of the subject S on a display unit such as a liquid crystal display, so that the measurer can use the scapula model of the subject S to calculate the left and right scapulae of the subject S. position can be explained to the subject S and evaluated.

It should be noted that, as described above, the points required from the first scapula model to the eighth scapula model are different. Therefore, the first acquisition control unit 102 and the second acquisition control unit 103 may appropriately change the acquisition target points according to the target scapula model.

Further, in the above description, the calculation control unit 104 calculates the distance between two points and the angle between three points. I don't mind.

Now, if it is desired to examine the positions of the right and left shoulder blades of the subject S in more detail, the following processing may be performed. That is, when the calculation control unit 104 completes the calculation, the evaluation control unit 105 of the terminal device 12 determines the surface of the back of the subject S in a posture different from a predetermined posture (normal posture) (for example, a stooped posture, a stretched posture). Measurement of a three-dimensional point cloud and acquisition of a plurality of points are performed, and the distance and angle are calculated using the same combination of points as the combination of points used in the calculated distance and angle, and a predetermined posture and angle are calculated. A change in the position of the right and left scapula of the subject S is evaluated by calculating a change in the distance from the different postures and a change in the angle from the predetermined posture to the different postures (FIG. 2: S105). Here, the plurality of points are, for example, any combination of the cervical vertebrae point C7, the thoracic vertebrae point T1, the left upper scapula point A, the right upper scapula point B, the left lower scapula point C, and the right lower scapula point D Become.

The evaluation method of the evaluation control unit 105 is not particularly limited. For example, as shown in FIG. 10, when adopting the fourth scapula model, first, the subject S takes a normal posture, and then the three-dimensional point cloud of the back surface of the subject S is measured. , the cervical vertebra point C7, the thoracic vertebra point T1, the left upper scapula point A, the right upper scapula point B, the left lower scapula point C, and the right lower scapula point D are obtained, and these six points are combined. , the distance and angle in the normal posture are calculated. Therefore, the measurer next asks the subject S to take a stooped posture different from the normal posture, and instructs the terminal device 11, so that the evaluation control unit 105 of the terminal device 11 performs the above-mentioned S101 to S104 respectively. The distance and angle in the stooped posture are calculated by causing the control unit to perform the calculation. The evaluation control unit 105 then calculates a change in the distance between the normal posture and the stooped posture and a change in the angle between the normal posture and the stooped posture. Here, the change can be, for example, the difference in the distance between the normal posture and the stooped posture or the ratio of the distance of the stooped posture to the distance of the normal posture. In this way, after having the same subject S assume different postures, the distance and angle for each posture are calculated, and the changes in the distance and angle are calculated. It is possible to quantify changes in the position of the blade, and to estimate the degree of tension and relaxation of the muscles around the left and right shoulder blades.

Here, the different postures can include the stretched posture in addition to the stooped posture. may calculate the distance and angle in the stretched posture, and calculate the change in the distance between the normal posture and the stretched posture and the change in the angle between the normal posture and the stretched posture. By calculating the distance and angle of each point in a plurality of postures and calculating the change in the distance and angle accompanying the change in posture, it is possible to more specifically evaluate the change in the position of the left and right shoulder blades.

In this way, a database of a plurality of subjects S can be created by quantifying the changes in the positions of the left and right scapulae. As described above, since it is suggested that there is a close relationship between the position of the left and right shoulder blades and the mental disorder, psychological situation, and psychological load, for example, the positions of the left and right shoulder blades of the subject S or their Estimate the psychological state of the subject S by associating the change with the psychological state of the subject S, for example, by measuring the positions of the left and right scapulae of the predetermined subject S or the changes thereof. is also possible. Of course, it is also an effective tool for verifying the degree of straight neck of the subject S.

Further, in the present invention, the positions of the left and right scapulae of the subject S or their changes can be quantified, so application to various fields is expected. For example, subject S before and after treatment such as frozen shoulder, rotator cuff injury, straight neck and hernia, orthopedic treatment and rehabilitation, massage therapy, heat therapy, exercise therapy, rest/drug therapy, acupuncture and moxibustion in addition to stiff shoulders By quantifying the positions of the left and right scapulae or their changes, it is possible to grasp the specific therapeutic effects numerically. Treatment is not limited to medical care, and can be actively applied to a wide variety of fields. For example, in the field of sports, verification of deterioration in performance, and in the field of beauty, verification of a posture that looks young can be mentioned. Furthermore, in the present invention, the degree of stress of the subject S can also be evaluated from the positions of the left and right scapulae of the subject S or their changes.

Further, in the present invention, the terminal device 11 is configured to include each control unit, but it may be configured to store a program for realizing each control unit in a storage medium and provide the storage medium. In this configuration, the program is read by a predetermined terminal device, and the terminal device realizes each control unit. In that case, the program itself read from the recording medium exhibits the effects of the present invention.

It is also possible to provide the steps executed by each control unit as a scapula position calculation method according to the present invention. For example, the measurer uses the three-dimensional point cloud measuring instrument 10 to measure the three-dimensional point cloud of the back surface of the subject S, and acquires the spine point, the left shoulder blade point, and the right shoulder blade point from among them. Then, the positions of the left and right shoulder blades of the subject S may be calculated using the distances and angles of these points.

EXAMPLES The present invention will be specifically described below with reference to Examples, but the present invention is not limited thereto.

Next, the measurer shoots the back of the subject S including the calibration plate 10a from the first direction with the camera 10b, then the measurer moves the camera 10b without moving the back of the subject S, The back of the subject S including the calibration plate 10a was photographed from a second direction different from the first direction. As a result, two captured images captured in the first direction and the second direction were acquired.

On the other hand, the terminal device 11 is provided with software for calculating a three-dimensional point cloud of the back surface of the subject S in the photographed image based on the two photographed images and the relative positional information of the four marks on the calibration plate 10a. After installing the software, the measurer started the software and input two captured images into the software to measure the three-dimensional point cloud of the back surface of the subject S in the captured images. Here, software functioned as the measurement control unit 101 .

Here, the software automatically recognizes the circular marks at the four corners of the calibration plate 10a and the circular sticker pasted on the back surface of the subject S, and acquires the three-dimensional coordinate values of each of the marks and stickers. It is configured to Therefore, as shown in FIG. 10B, when two photographed images were input to the software, the three-dimensional coordinate values of the mark and sticker were automatically acquired. Here, software functioned as the first acquisition control unit 102 and the second acquisition control unit 103 . The origin of the displayed three-dimensional coordinate values is shown at a predetermined position.

In addition, this software plots the three-dimensional coordinate values of the obtained points on the xyz coordinate system of the three-dimensional space and connects the points with lines. Here, when constructing the first scapula model from each point, for example, the software calculates the distance and angle from the combination of each point corresponding to the first scapula model, as shown in FIG. As shown, a photograph showing the position of each point on the skeleton model, the first scapula model using each point, and the distance and angle using each point are displayed. Here, software functions as the calculation control unit 104 .

The distance and angle from the first scapula model to the eighth scapula model are calculated by, for example, the measurer inputting a switching instruction to the software. Thus, it is possible to calculate the distance and the angle from the combination of each point.

Next, the measurer asked the subject S to take a stooped posture different from the normal posture, and using software, as shown in FIG. , with the acquisition of multiple points. Further, the measurer asked the subject S to stretch his back, and similarly measured the three-dimensional point cloud of the surface of the back of the subject S in the stretched posture and acquired a plurality of points. Then, when the measurer inputs an evaluation instruction into the software, the software uses the distance and angle in the normal posture as the reference, and the same combination of points as the combination of points used in the distance and angle calculated in the normal posture. The distance and angle in the stooped posture were calculated, and the change in the distance between the normal posture and the stooped posture and the change in the angle between the normal posture and the stooped posture were calculated. Here, as the change, the difference in the distance between the normal posture and the stooped posture and the ratio of the distance of the stooped posture to the distance of the normal posture were adopted. The software similarly calculated the change in the distance between the normal posture and the stretched posture, and the change in the angle between the normal posture and the stretched posture. Here, software functions as the evaluation control unit 105 .

As shown in FIG. 21, the software displays the first scapula models in the normal posture, the stooped posture, and the stretched posture, the respective distances and angles, and changes in the distance and angles. Thereby, the measurer can easily grasp the change in the position of the right and left scapula accompanying the change in the posture of the subject S. In addition to the first scapula model, as shown in FIGS. 22 to 28, the software also supports the second scapula model to the eighth scapula model. It displays the distance and angle in posture and posture, and the change in distance and change in angle. In this way, it is possible to verify distances and angles from various scapula models.
