The motion recognition device 20 may recognize the motion of the subject by obtaining the distance and coordinates of the subject.

Various conventional techniques can be used as the motion recognition device 20 of the present invention. However, it may be preferable to use a lidar as the motion recognition device 20 of the present invention.

Light detection and ranging (LiDAR) uses a light source, such as a laser, and measures the time from reflecting off the subject to returning to the sensor to obtain the distance and coordinates of the subject.

On the other hand, as the motion recognition device 20 of the present invention, general non-laser light can be emitted. Since the motion recognition device 20 of the present invention is frequently used for obtaining a distance and coordinates of a short-distance object, even when a general light emitting diode (LED) is used instead of a laser having a high light density, there is a problem in scanning a short-distance area. This is because it is possible to perform precise tracking rather than laser light.

In addition, the motion recognition device 20 according to an embodiment of the present invention may perform tracking by applying a VCSEL or a laser as well as an LED as a light source.

As a typical example, a motion recognition device 20 is installed on a display device such as a monitor or a TV without a touch panel, so that an effect such as a touch function is inserted into the corresponding monitor or TV is exerted.

1 is a flowchart of a method of controlling a motion recognition device according to a recognition position of a gesture according to an embodiment of the present invention, and FIGS. 2 to 9 are views for helping the description of FIG. 1, and various according to embodiments of the present invention The situation is illustrated.

Hereinafter, a method of controlling a motion recognition device according to a recognition position of a gesture according to an embodiment of the present invention will be described with reference to FIGS. 1 to 9.

The subject of the method of controlling the motion recognition device according to the recognition position of the gesture according to the embodiment of the present invention is a computer, and may be the server 100 or the control device 10.

First, the region dividing unit 110 divides the scanning region of the lidar 20 into two or more stages. (Step S500)

More specifically, the region dividing unit 110 divides the scanning region of the lidar 20 into two or more stages horizontally or vertically based on the display device 600 on which the lidar 20 is installed.

2 is a view illustrating that the scanning area of the lidar 20 is divided into two stages.

As a simple example, as shown in FIG. 2, the region dividing unit 110 divides the scanning regions of the lidar 20 into two sides from the lidar 20 in an orthogonal direction, that is, with respect to the display device 600 as a vertical reference. can do.

Of course, the area dividing unit 110 may divide the scanning area into three or more, or the display device 600 may be divided up and down based on a horizontal basis, or in a diagonal direction.

In the embodiment of the present invention, it will be exemplified as being divided into two sides as shown in FIG. 2 in consideration of the convenience of the user and convenience of description.

As shown in FIG. 2, in step S500, the region dividing unit 110 vertically scans the scanning region of the rider 20 with the scanning region of the rider 20 vertically based on the display device 600 on which the rider 20 is installed. It was divided into a first stage and a second stage.

In addition, step S500 may further include irradiating a guide light to the boundary between the divided stages through a laser device.

3 is a diagram illustrating that a laser device irradiates guide light to a boundary between stages.

Users who are unfamiliar with segmentation may not know exactly where the boundary line is. Accordingly, by guiding the guide light in parallel with the display device 600 through the laser device as shown in FIG. 3, the user can inform the stage boundary.

In addition, the laser device may be provided with the lidar 20 to irradiate guide light as shown in FIG. 3, or may be separately provided and installed in the display device 600.

For example, while the lidar 20 is installed at the upper center of the display device 600 as shown in FIG. 3, when the stage is divided into upper and lower, the laser device is installed at the center of the side of the display device 600 to horizontally Guide light is directed in the direction.

Next to step S500, the reception unit 150 receives gesture information of the subject recognized by the lidar 20 and stage information in which the gesture of the subject is recognized. (Step S520)

More specifically, it means that the receiving unit 150 receives information on the gesture of the subject recognized through the lidar 20 and information on the stage on which the subject is recognized.

Referring to FIG. 3, the receiving unit 150 receives gesture information in which a user's second finger is spread as gesture information of a subject.

In addition, since the user took a gesture at the first stage, the receiver 150 receives information indicating that the corresponding gesture was input at the first stage.

Next, in step S520, the controller 130 generates a control signal corresponding to a gesture of the subject and a stage in which the subject is recognized. (Step S540)

Referring to FIG. 3, for example, the control unit 130 determines a control signal by matching the gesture information on which the user's second finger is spread and the first stage information together.

If the user takes a gesture on the right side of the display device 600, that is, the second stage, the control unit 130 generates a control signal different from the above.

For example, the gesture of spreading the second finger is the page control of the presentation being output to the display device 600, and when a gesture is input to the first stage, it moves to the previous page, and when a gesture is input to the second stage, it moves to the next page. As described above, the control signal can be distinguished.

As described above, the control unit 130 considers the gesture information and the stage information together, generates a control signal corresponding thereto, and transmits the control signal to the display device 600 or a computer outputting the display device 600. .

In one embodiment, the control unit 130 may further include a step of flashing the guide light when there is no control signal allocated to the gesture of the subject recognized through the lidar 20.

More specifically, when the same gesture is repeatedly input from the user and there is no control signal allocated to the gesture, the controller 130 determines that the user is mistaken for the gesture and causes the guide light to flash.

4 is a diagram illustrating that the gesture of the subject is recognized at the boundary of the stage.

Referring to FIG. 4, according to an embodiment, when the position where the gesture of the subject is recognized is the boundary area of the divided stage, the controller 130 responds according to the boundary area in which the gesture of the subject and the gesture of the subject are recognized. It may further include the step of generating a control signal.

For example, as illustrated above, the gesture of spreading the second finger is the page control of the presentation being output to the display device 600, and when the gesture is input to the first stage, it moves to the previous page, and the gesture is input to the second stage. If it is, the control signal can be classified as moving to the next page.

In addition, when a gesture is input at a boundary between the first stage and the second stage, the controller 130 may generate a control signal for operating or stopping the automatic playback of the presentation.

At this time, the area of the boundary line may have a predetermined predetermined width, and in the expanded embodiment, two laser devices are provided on the lidar 20, and two laser devices irradiate guide light, so that the left side is the first stage and the right side. May be divided into a second stage and a boundary area between the two guide lights.

5 is a diagram illustrating that the gesture of the subject is moved from the first stage to the second stage.

Referring to FIG. 5, in one embodiment, when it is recognized that a gesture of an object moves two or more stages, the control unit 130 considers the sequence of the gesture and the stage moved during the gesture execution, and controls corresponding thereto. The method may further include generating a signal.

For example, as illustrated in FIG. 5, when the user inputs a gesture in which the second finger is spread, but moves from the first stage to the second stage and inputs the gesture, the controller 130 generates a different control signal differently from the above. Means

More specifically, when it is recognized that the gesture shown in FIG. 5 moves from the first stage to the second stage in the case of control of the presentation being output to the display device 600, the controller 130 displays the page of the presentation. A control signal that turns to the next 2 pages can be generated.

Conversely, when it is recognized that the gesture shown in FIG. 5 moves from the second stage to the first stage, the control unit 130 may generate a control signal for turning the page of the presentation to two pages or more.

Also, only the two stages are exemplified above, and can be applied to three or four stages.

For example, the controller 130 may generate another control signal if the user's gesture is moved in the order of the first stage, the second stage, and the third stage. Alternatively, the first stage, the third stage, If it is moved in the order of the second stage, another control signal can be generated.

6 is a diagram illustrating a case in which the subject recognized through the lidar 20 is the left hand of the user.

Referring to FIG. 6, in step S520, in one embodiment, the controller 130 determines whether the subject is the user's right or left hand through gesture information of the recognized subject, and the controller 130 determines whether the subject is the user's The method may further include generating a control signal according to whether the information is a right hand or a left hand, gesture information of the subject, and stage information on which the gesture of the subject is recognized.

For example, in FIG. 6, the same gesture information as in FIG. 3 is input, but in FIG. 3, gesture information is input through the user's right hand, and in FIG. 6, gesture information is input through the user's left hand.

As described above, since the control signal is further classified according to the right hand and the left hand, there is an advantage that more various control signals can be applied.

Further, it is determined whether the user's right hand or left hand is based on the object information, using the shape of the user's finger, the shape of the finger folded, the angle of the arm extended from the hand, etc. in the object information scanned through the liar 20. I can judge.

7 is a diagram illustrating a case in which the subject recognized through the lidar 20 is both hands of the user.

Referring to FIG. 7, in one embodiment, when the controller 130 determines that the recognized subject is both hands of the user, left-hand gesture information of the subject, stage information of the left-hand gesture recognition, right-hand gesture information of the subject, and The right hand gesture may further include generating a control signal according to the recognized stage information.

In more detail, when the user inputs the first gesture to the first stage with the left hand and the first gesture to the second stage with the right hand, the first control signal may be generated.

Then, when the user inputs the second gesture to the first stage with the left hand and the first gesture to the second stage with the right hand, a second control signal may be generated.

Then, when the user inputs the first gesture to the first stage with the left hand and the second gesture to the second stage with the right hand, a third control signal may be generated.

Then, when the user inputs the second gesture to the first stage with the left hand and the second gesture to the second stage with the right hand, a fourth control signal may be generated.

As described above, since only four types of control signals can be input with only two types of gestures, it is possible to control various objects by generating various control signals even if a limited gesture is used.

In addition, the more divided stages, the more types of gestures, the more control signals can be generated.

8 is a diagram illustrating that different control signals are generated according to the distance of a subject recognized through the lidar 20.

Referring to FIG. 8, in one embodiment, the control unit 130 extracts the size information of the subject through gesture information of the subject, and calculates the vertical distance between the lidar 20 and the subject through the size information of the subject. And generating a control signal according to a gesture of the subject, a stage in which the gesture of the subject is recognized, and a vertical distance between the lidar 20 and the subject.

2 to 7 above, the first and second stages were divided into left and right sides.

At this time, it is exemplified that the control signal may be different depending on the distance between the subject and the lidar 20.

8, the first gesture information is input at the first position 410 and the first gesture information at the second position 420 is the same gesture information, but the distance between the subject and the liar 20 is different. Therefore, different control signals are generated.

In addition, the extraction step may further include a step of calculating the actual size of the subject through the information of the subject recognized by the calculator 170 through the lidar 20.

In addition, in the vertical distance calculation step, the calculator 170 may calculate the vertical distance between the lidar 20 and the subject through the size information of the subject recognized through the lidar 20 and the actual size information of the subject. .

Through this, the calculation unit 170 calculates the actual size of the subject (the user's hand) and compares the size information of the subject (the user's hand) and the actual size information scanned through the lidar 20 to the lidar ( 20) and the vertical distance between the subject can be calculated.

In this case, since the position on the display device 600 needs to be calculated as a reference, the object position on the display device 600 can be calculated using the vertical distance without using the linear distance between the lidar 20 and the subject. do.

In one embodiment, the control unit 130 extracts and specifies the subject from the object scanned through the lidar 20, and the control unit 130 specifies the specified object from the object scanned through the lidar 20. The method may further include correcting that the size of the subject varies by tracking the subject.

More specifically, the control method of the motion recognition device according to the recognition position of the gesture according to the embodiment of the present invention recognizes and recognizes an object in the scanning area of the lidar, and if the object is specified, according to the distance between the lidar and the object The subject can be identified by correcting that the size of the subject is variable.

For example, when the user takes a gesture using the right hand, the controller 130 identifies the user's right hand as the subject, recognizes the gesture by tracking the right hand as the specified subject from the data scanned through the lidar, and Correct the size of the right hand, which changes according to the distance between Ida and the right hand.

In addition, since the user's right hand is specified as a subject, the controller 130 may recognize that the target is not a subject even if a body or other object other than the right hand is recognized, such as a foot or a head.

Therefore, since the subject is recognized by the controller 130 as described above, since no error occurs in recognition, it is possible to guarantee the autonomy of movement to the user.
