USER-RECOGNIZED WALKING MOTION MEASUREMENT SYSTEM AND METHOD FOR MEASURING WALKING MOTION USING THE SAME}

The present invention relates to a user recognition walking motion measuring system and a walking motion measuring method using the same. More specifically, the image projecting the walking motion of the user is projected, and the walking motion of the user corresponding to the projected image is sensed and measured. The present invention relates to a user recognition walking motion measuring system for calculating statistics and outputting the calculated walking motion record, and a walking motion measuring method using the same.

In the past, the patient's abnormal gait was confirmed by the naked eye of a doctor or other observer. However, this method is diagnosed by the doctor's experience and observation, and has the limitation that the analysis result may be different under the same conditions. In addition, even if the treatment for abnormal walking progresses, it is difficult to compare with the past walking state. If the gait analysis is not done properly, it has caused great discomfort to the patient such as causing body asymmetry.

Gait measurement and analysis has been actively conducted on the EMG to calculate and use the joint moment, and to identify muscle activity. In recent years, it has evolved with computer modeling when it is possible to estimate muscle strength through optimization techniques.

However, the gait measurement and analysis described is limited only to institutions equipped with expensive equipment and medical staff. It is a reality that ordinary people do not measure and analyze their walking posture in real life.

1 is a view showing a user recognition walking motion measurement system according to an embodiment of the present invention. 2 is an operation of the user recognition walking motion measurement system according to an embodiment of the present invention.

1 and 2, the user recognition walking motion measuring system 10 according to the present embodiment includes an image output unit 100 for projecting a virtual walking guide image G for inducing a walking motion of a user. Receiving the motion detection information of the user from the motion detection unit 200 and the motion detection unit 200 for detecting the walking motion of the user corresponding to the guide image (G) and the location of the specified body part of the user the user The operation determining unit 300 may determine whether the motion detection information of the controller satisfies a preset condition. In addition, the display unit 400 may display a content screen for guiding the user.

In the user recognition walking motion measurement system 10 according to an exemplary embodiment of the present invention, the virtual walking guide image G is projected onto the ground of the user's position through the image output unit 100. The projected walking guide image G may project an image inducing a walking operation of the user. The user may perform a walking operation in response to the projected walking guide image G, and the motion detection unit 200 may measure and detect the walking operation of the user.

In addition, the walking guide image projected in the walking space of the user is a walking program based on ICT (Information and Communication Technology), which induces the user's senses and perceptions, and expands the experience and emotion similar to the real life, It may be realistic interactive content that virtual objects interact with. The immersive interactive content may be a virtual object (walking guide image G, for example, a guide line presenting a direction to be walked by the user or a user walking in order to induce a walking action to be taken by the user according to a walking program). Coordinate information) and information about the coordinates, the order, the interval of change of the coordinates, and the like. The coordinate information may be optimally provided to the user according to the user's age, gender, physical fitness, exercise amount, exercise program under training, and the like.

The motion detection unit 200 may recognize the walking motion of the user in the front walking space (the space where the walking guide image G is projected). The motion detector 200 may include at least one camera, a depth camera, an infrared sensor, or a combination thereof to detect a walking motion of the user and the user and a location of a specified body part of the user. Here, the designated body part of the user may be set in advance, for example, the foot, the heart part, the head, the knee, and the like may be set. The motion detection unit 200 shown in FIGS. 1 and 2 is detected in front of the user, but is not limited thereto. A plurality of motion detection units 200 may be installed around the user (front, rear, left and right) to display a multi-view image. It may be generated to recognize the walking motion of the user. That is, the motion detection unit 200 may detect the walking space of the user in three-dimensional or multi-view. The user recognition gait motion measurement system 10 provides an optimized and lively three-dimensional gait interface for the user by using the user's walking motion, the user's location and spatial information measured and collected by the motion detection unit 200, and provides a precise user's Enable walking motion recognition. The camera may be a camera for photographing a left image and a right image for generating a 3D image, and may implement a multiview using a plurality of cameras. Also, data about parallax of the left and right images may be extracted from a depth camera of a depth camera and a 3D image, and used to convert a distance from an object.

For example, the motion detection unit 200 may transmit infrared rays toward the human body within the recognition range, detect the infrared signal reflected from the human body, and display important joint parts of the human body as a plurality of points. Accordingly, the movement, speed, and position of the human body can be recognized. In addition, the motion detection unit 200 may separate one person by a method such as recognizing a person at the closest distance when several people are located within a recognition range, and separately recognizes several people separately. Can be.

The motion detection unit 200 may be a device capable of motion capture or voice recognition. For example, it may be a Computational Camera. Computational cameras go one step further than the traditional camera method, in which the reflected light of the subject is obtained from a camera arm box transmitted through the lens, and the information is processed by reprocessing the image through an operation on the image of the subject coming through the lens. Camera to create a captured image. Among such computational cameras, there is a 3D depth recognition camera and can be used for gesture recognition, obstacle recognition, 3D scanning, etc. according to the recognition distance.

The motion detection information generated by the motion detection unit 200 may be digital data indicating the motion and location of the user detected by the motion detection unit 200, and the motion detection information is a plurality of expressions representing important joint parts of the user. Location information of the three dots, body part information of a predetermined user, and depth information may be included.

The image output unit 100 may project a virtual walking guide image G for inducing a walking operation of the user to a space where the user is located. The image output unit 100 may include a projector 110 and a reflector 120. The image output unit 100 can sufficiently project the image even in a place where a sufficient projection distance is not secured, such as a low ceiling, and provide a walking guide image G for inducing a walking operation at the same position even with a change in height. Can project.

The projector unit 110 may project a virtual object (walking guide image G) for performing a walking program based on the sensational interactive content to the reflecting unit 120. The project unit 110 may be compatible with various wired and wireless interfaces such as HDMI, RGB, BNC, and Wireless HD. The position and the projection angle of the projector 110 may be variously changed to adjust the size and position of the walking guide image G projected according to the type of the walking program. For example, the projector 110 may move up, down, left and right and rotate 360 degrees through a rail or a bracket.

The reflector 120 may reflect the walking guide image G projected from the projector 110 onto the ground of the walking space of the user. The reflector 120 may be formed of any one of a flat mirror, a convex mirror, a concave mirror, or an atypical mirror, and according to the type and characteristic of a walking program, the walking guide image G may be formed in the projector 110. The size of the walking space can be adjusted by adjusting the projection distance to the floor to be projected. For example, when the reflector 120 is implemented as a planar mirror, the projection distance is twice as large as the distance between the planar mirrors in the projector unit 110 than when the projector unit 110 is directly projected onto the floor. Increased effect can be obtained. In addition, when the reflecting unit 120 is implemented as a convex mirror, the distance between the convex mirror and the distance according to the magnification of the convex mirror in the projector unit 110 is greater than when the projector unit 110 is directly projected onto the bottom surface. The effect of increasing the projection distance can be obtained. In addition, when the reflecting unit 120 is implemented as a concave mirror, the projection distance is shorter than when the projector unit 110 is directly projected on the bottom surface, but the image projected by the projector unit 110 concentrates the light projected by the clear image even in a bright place. There is an effect that can be obtained. In addition, when the reflector 120 is implemented as an atypical mirror, the projection distance can be increased to secure an enlarged virtual motion space, and the angle reflected by the mirror to be projected on the floor is not vertical. You can also correct distortion on the screen. As an example, the reflector 120 may apply a paint having a higher reflection coefficient than that of a general mirror to acrylic or plastic so that distortion of an image according to a projected distance does not occur.

In addition, the reflector 120 may move up, down, left, and right or rotate to adjust an angle reflected back and forth or left and right. As an example, the reflector 120 may be moved up, down, left and right and rotated 360 degrees through a rail or bracket. Through this, even after installation of the user recognition walking motion measuring system 10, the location where the walking guide image G is projected may be variously changed according to the surrounding environment to be walked.

Meanwhile, FIG. 1 shows that the reflector 120 is formed as one reflection mirror, but this is just one example. The reflector 120 includes a plurality of reflection mirrors to guide a walking guide image G between the reflection mirrors. ), The projection distance between the projector 110 and the ground can be further extended. As an example, the projector 110 is installed in the lower part of the user recognition content providing system 10, and some reflective mirrors are zigzag in the middle, and then finally projected to the floor through a reflective mirror installed on the ceiling. Can be.

In addition, the image output unit 100 may include a plurality of projectors 110. In this case, a plurality of screens may be output through different reflecting units 120, respectively, to produce an image effect of being overlapped with each other or being output adjacently.

Meanwhile, in another embodiment, the image output unit 100 may omit the reflection unit 120 so that the walking guide image G projected from the projector 110 may be directly projected onto the floor.

The motion determining unit 300 may receive the motion detection information of the user from the motion detection unit 200 and determine whether the motion detection information meets a preset condition. As described above, the motion detection information may be location and motion information of a main joint part and location and motion information of a predetermined body part such as a shoulder, a head, a chest, a knee, a foot, and a hand.

The preset condition may be an operation condition of the user that appears during the walking operation or a position of the foot of the user. For example, an operation condition of the user that appears during the walking operation may be that one knee of the user rises above a certain height, or the user's foot is positioned at a virtual object position projected onto the ground. Here, the predetermined height is a set value. For example, when the position of the knee rises to a height of 10 cm or more, the operation determining unit 300 may determine that the setting condition is met. In addition, when the user walks along the walking guide image G projected on the ground, it may be a setting condition that the user actually steps on the next foot. In this case, when the motion detecting unit 200 detects the user's foot in the position or area of the point where the user should step on the next foot, the operation determining unit 300 may determine that it is a match.

If it is determined that the operation determining unit 300 matches, the next predetermined event set according to the walking program may be executed. For example, in the walking guide image G, all images may be projected before the user walks, and the walking guide image G may be displayed or emphasized as the user walks. In this case, when the user is walking and the user determines that the operation determination unit 300 is matched by stepping on the point where the user should step on, the image output unit 100 determines the point where the user should step next ( You can fire an event that projects or highlights the projected virtual object that should take the next step.

That is, the walking motion measurement sequence may be progressed when the condition determination unit 300 determines that the received walking detection information is met according to a set condition, and if the condition determination unit 300 does not determine that it matches, the next event does not occur. It may not be.

The display unit 400 may display a content screen for guiding a user. Herein, the content screen may be an interface screen for the user to execute a walking program, or may be an exemplary operation and instructions to be followed by the user in the walking program. In addition, the display unit 400 may output the user's motion detected by the motion detection unit 200, and outputs information on the movement and the result of the user's exercise according to the user's position or direction change while walking. can do.

3 is a diagram illustrating that the walking guide image G is projected onto the ground according to an embodiment of the present invention.

Referring to FIG. 3, the walking guide image G projected onto the ground may include a user's starting point G0, walking guide points G1 and G2, a menu interface I1 selectable by the user, and an execution time. It may include an interface I2 for measuring. Here, the walking guide image G may be output all images before departure or may be output stepwise according to the walking position of the user. If the user stands at the starting point G0, the motion detecting unit 200 detects the position of the user, and if the detected user's position matches the position of the projected starting point G0 area, the operation determining unit 300. The user may determine that the user has performed an operation in accordance with the starting operation condition.

The projected objects G0, G1, G2, and I1 are output to an area having a predetermined area. The user recognition walking motion measuring system 10 may determine the area of the projected objects G0, G1, G2, and I1 on the system 10 by using the positions of the boundary points of the projected objects G0, G1, G2, and I1. Can be. The motion detection unit 200 may measure the position of the user's foot. When the position of the user's foot is measured within the determined object areas G0, G1, G2, and I1, the operation determining unit 300 may determine the object projected by the user. It may be determined that the user has stepped on (G0, G1, G2, I1) or the user has stepped on the projected object.

When the projected walking guide image is not projected at the same time but is projected in stages, when the operation determining unit 300 determines that the user has stepped on the first object G1, the user's opposite knee is raised above a certain height. When the sensing unit 200 detects the motion determining unit 300 that receives the motion sensing information in which the opposite knee of the user rises by a predetermined height or more, the operation determining unit 300 receives the second object G2 while the user steps on the first object G1. It can be judged as a condition of the state of walking toward. In this case, the image output unit 100 may project the second object G2 or, if the projected state, may emphasize the second object G2.

When the user walks along the walking guide images G1 and G2 that satisfy the departure condition, the motion detection unit 200 may measure and record the position of the foot that the user stands while walking. In addition, the motion detection unit 200 may measure the position of the designated body part of the user as described above. The designated body part may be the position of the foot, but may be the chest center or the head center of the user.

Figure 4 shows the measurement of the position of the center of the head (P1, P2, P3) of the user according to an embodiment of the present invention. The walking posture may differ from person to person. There may be people walking in a straight line in the right posture, or people walking in a zigzag in the wrong posture. In addition, the lower body is in a straight line, the upper body movement may swing from side to side may be a person walking. In order to measure such various incorrect walking postures, the upper body balance expressed during walking can be measured. Referring to FIG. 4, the motion detection unit 200 may measure head center positions P1, P2, and P3 of a user walking to measure upper body balance. The statistical calculation unit, which will be described later, allows the user to compare the walking upper body balance with the tracking line TL generated by tracking the measured head center positions P1, P2 and P3 and the center line GL of the walking guide image G1. You can make it perceivable.

In addition, the vertical separation distance between the tracking line TL and the center line GL of the walking guide image G1 may be measured, and the measured separation distance may be used to calculate the upper body balance statistics of the user. .

5 is a diagram illustrating a screen showing statistics of a walking motion of a user according to an exemplary embodiment of the present invention.

Referring to FIG. 5, the user recognition walking motion measuring system 10 may determine one or more of a statistical value, a statistical graph, or a user's actual walking record calculated based on a distance between the foot of the user and the position of the walking guide image. It may include a statistical calculation unit for outputting.

When the walking calculation is completed, the statistical calculation unit may display the walking motion result screen R1 based on the measured walking motion record. The walking motion result screen R1 may display the walking motion balance of the user as a score. The score may be represented by converting the walking balance into 0 to 100 points according to the result data. In addition, when the user does not complete the walking operation within the time limit, the score may be displayed as 0.

The statistical calculation unit may display a statistical graph based on the converted walking balance score. For example, the statistical graph may represent a distribution curve for each score based on the average score. Here, the score conversion weight or the graph conversion weight of the walking balance is only one example, but is not limited thereto.

The walking operation result screen R1 may include a lower body balance record R2 and an upper body balance record R3. The lower body balance recording R2 may show the centerline of the projected walking guide image together with the traces of the position of the ground (ie, the position of the stepped foot) that the user stepped on while walking. In this case, the user can directly check what is wrong with his lower body balance while walking.

The upper body balance record R3 may show the centerline of the projected walking guide image together with the center trace of the upper body while the user walks, as in the lower body balance record R2. In this case, the user may directly check whether there is a problem in his upper body balance while walking.

Alternatively, the walking operation result screen R1 may include a foot position recording R2 and a distance recording R3 from the walking guide image.

6 is a diagram showing the separation distance of the lower body balance recording according to an embodiment of the present invention.

Referring to FIG. 6, the separation distance at which the recorded footprint trace is vertically deviated from the center line of the walking guide image may be measured. The statistical calculation unit may calculate a walking balance score based on the separation distance. For example, every footprint trace measures the separation distance, and as the separation distance increases by 1 cm, two points can be subtracted. If the total distance is 50cm or more, the walking balance score can be treated as 0 points.

7 to 8 are diagrams showing a state of use of the user recognition gait motion measurement system according to an embodiment of the present invention.

7 to 8, the image output unit 100 may output an interface screen on which a menu can be selected through a user's operation. When the user raises his foot on the interface screen and keeps his knees bent for the first selection time, the user recognition walking motion measuring system 10 compares the position of the foot corresponding to the bent knee of the user with the interface screen. It can generate a predetermined event. That is, when the motion detection unit 200 recognizes the user's motion and maintains the user's knee bent on one leg for the first selection time, the user recognition gait motion measuring system 10 may display the user's motion on the interface screen. The button event corresponding to the position of the foot corresponding to the bent knee may be generated. As an example, the first selection time may be set to 2 seconds.

In another embodiment, when the user raises both feet on the interface screen and bends both knees, the first selection time is greater than the first selection time when the user raises one foot on the interface screen and bends the knee. Can be set short. As an example, the first selection time in this case may be set to 1.7 seconds. In relation to the user recognition gait motion measurement system 10 according to an exemplary embodiment of the present invention, a user may bend a knee to select a particular button on an interface screen in terms of "quick selection", 1 The selection time can be defined in terms such as "quick selection time".

In another embodiment, if the user's knee is bent after the user puts the foot on the interface screen, the user recognition walking motion measuring system 10 may determine the position of the foot corresponding to the bent knee of the user and the interface screen. By comparison, certain events can be generated.

In another embodiment, when the user places a foot on the interface screen, the user recognition walking motion measuring system 10 compares the position of the foot of the user with the interface screen and places the foot on the interface screen. When the user's knee corresponding to the foot is bent and extended, a predetermined event may be generated according to a result of comparing the position of the foot corresponding to the user's bent and extended knee with the interface screen. That is, when the motion detection unit 200 recognizes the user's motion and the user bends and straightens the knee of one leg, the user recognition walking motion measuring system 10 may have a foot corresponding to the user's bent and extended knee on the interface screen. You can fire an event for a button that matches its position.

9 to 12 are flowcharts illustrating a method for measuring a user recognition walking motion according to an embodiment of the present invention. 6 to 9 may be performed by the user recognition walking motion measurement system 10 according to an embodiment of the present invention.

Description of the user recognition walking motion measurement system 10 will be omitted.

Referring to FIG. 9, in the user recognition gait motion measuring method according to an exemplary embodiment of the present disclosure, a projection step (S900) of the image output unit 100 projecting a virtual walking guide image for inducing a gait motion of a user, The motion detecting unit 200 detects the walking operation of the user corresponding to the walking guide image and the position of the body part of the user (S910) and the operation determining unit 300 moves the user from the motion detecting unit 200. The method may include determining whether the user's motion detection information meets a preset condition by receiving the detection information (S920).

A user recognition walking motion measuring method including a projection step S900, a detection step S910, and a determination step S920 illustrated in FIG. 9 is generally observed by a third party, which is a method of measuring walking, or by using a walking device. There may be a difference between the method of measuring gait. The method of measuring gait using a walking apparatus may have advantages in terms of measurement data, but it is difficult to be used by the general public because it is used only by a professional institution. The third party's observation method is low in measurement reliability because inaccurate observation records are derived depending on the observer and the condition of the observer.

However, since the user recognition walking motion measuring method of FIG. 9 projects a general virtual walking guide image, the user may directly see the induced walking motion by eye, and thus, the user may easily understand the measuring method. In addition, the gait guide image can be easily modified in a variety of lines, S-shape, circular, etc. can present a gait program, and each gait program can be customized customized gait measurement for the purpose of gait measurement of the user. In particular, gait motion and position detection allows the user to directly check the detailed analysis results provided only by specialized institutions without the help of the institution.

Referring to FIG. 10, a method of measuring user recognition walking motion according to an exemplary embodiment of the present invention may include a statistical value, a statistical graph, or a user calculated based on a separation distance between a foot of a user of the statistical calculation unit and a position of a walking guide image. And outputting one or more of the actual walking records of (S1030).

At this time, in the detection step (S1010), when the user operates in response to the walking guide image of the user, the user may measure and record the position of the foot that the user steps on. The user may check the center line of the walking guide image and the traces of the feet measured and recorded by the motion detection unit 200 to determine whether there is a problem with his walking posture.

Referring to FIG. 11, a method of measuring a user's recognition walking motion according to another embodiment of the present invention may include a statistical value calculated based on a distance between a user's body part and a location of a walking guide image, a statistical graph, or a user's recognition walking motion. And outputting one or more of the actual walking records (S1130).

At this time, in the detection step (S1110), when the user operates in response to the walking guide image of the user, the position of the designated body part of the user may be measured. As described above, the body part may be, for example, a head center or a chest center as a part capable of measuring the upper body balance. The statistical calculation unit may display the trace of the central position of the recorded body part and the center line of the walking guide image so that the user may check the status of the upper body balance while walking.

Referring to FIG. 12, the method of measuring a user recognition walking motion according to an exemplary embodiment of the present disclosure may include a step (S1200) of displaying, by the display unit 400, a content screen for guiding the user. Herein, the content screen may be an exemplary operation and instruction phrase to be followed by the user.

Next, the image output unit 100 may include a step (S1210) of projecting the interface screen that can be selected through the user's operation. The user may select a menu of the interface screen through an operation corresponding to the projected interface screen.

When the walking motion measurement menu is selected, it may be continued to the projection step S1230 of projecting the walking guide image. When the walking guide image is projected, the user may start walking by seeing an exemplary operation and an instruction phrase output to the display unit 400.

When the gait is started, the motion detector 200 may measure and detect a user's gait and transmit motion detection information to the motion determination unit 300, and the motion determination unit 300 receives the received motion detection information in advance. A determination step (S1240) of determining whether the set condition is satisfied may be performed.

If it is determined that the motion detection information received by the operation determining unit 300 meets a preset condition, the image output unit 100 may project a walking guide image according to the following event.

For example, when the position of the user's knee rises by a certain height, for example, 10 cm or more, according to the walking guide image, the user recognition walking operation system 10 determines that the user is walking, and moves the next foot at the position where the user is currently walking. The walking guide image may be projected at the point where it is to be placed, or the walking guide image which is previously projected may be emphasized.

If the operation determining unit 300 does not meet the operating condition and meets the end condition, the operation determining unit 300 may terminate the running walking program (S1260), and may cause the statistical calculation unit to output walking measurement statistics to the display unit 400.
