Figure 1 shows a system block diagram of the service server 1000 for performing a method for providing auto-coaching information according to an embodiment of the present invention, and Figure 2 shows a system block diagram for performing a method for providing auto-coaching information according to an embodiment of the present invention. A flow chart for this is shown, and Figure 3 shows an application example of the method for providing auto-coaching information according to an embodiment of the present invention.

Referring to Figure 1, the service server 1000 for performing the method for providing auto-coaching information according to an embodiment of the present invention includes a motion analysis unit 1100, a physical quantity analysis unit 1200, a data storage unit 1300, and a data storage unit 1300. It includes a transceiver unit (1400) and an electrocardiogram analysis unit (1500).

The motion analysis unit 1100, the physical quantity analysis unit 1200, the data storage unit 1300, the data transmitting and receiving unit 1400, and the electrocardiogram analysis unit 1500 are wired or wirelessly so that they can exchange electrical signals with each other. can be connected

Hereinafter, a method for providing auto-coaching information according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

First, a step is included in which the motion analysis unit 1100 of the service server 1000 detects the user's motion transmitted from the first image collection device and extracts motion information (S110).

The overall movement of the user's body is analyzed by analyzing images or video images transmitted from the first image collection device. The motion analysis unit 1100 analyzes the user's body movements, movement of the center of gravity, rotation of the torso, and arm or leg movements.

For example, when a user makes a swing motion to hit a baseball, the motion analysis unit 1100 analyzes the movements of the user's head, torso, and legs to analyze images from the start of the swing to the end. do. Through this, motion information that can be used to generate analysis information about changes in the user's head position, changes in torso rotation, and changes in the center of gravity of the entire body due to movement of the legs can be extracted.

Here, in the step of extracting motion information, the ECG analysis unit 1500 of the service server 1000 generates the user's tension state information using the user's ECG information transmitted from the ECG sensing device attached to the user's body. , It may further include the step of transmitting the tension state information to the output device through the data transmitting and receiving unit 1400.

An electrocardiogram is a measurement of the potential related to heartbeat on the body surface. In addition to the standard 12-lead electrocardiogram, there is an exercise stress electrocardiogram and an activity electrocardiogram (Holter recording and event recording electrocardiogram). Any electrocardiogram sensing device attached to the user's body to measure electrocardiography can be applied as long as it is attached to the skin near the user's heart, or to areas such as wrists and ankles.

For example, a wristwatch-type electrocardiogram sensing device that can be attached to the user's wrist can be used. In order to be able to easily sense the electrocardiogram and not excessively restrict the user's movements, it is desirable to use an electrocardiogram sensing device that is designed to be worn like a wristwatch. However, any sensing device that can be attached to the body surface that can measure heartbeat-related potential other than the user's wrist can be applied.

A wristwatch-type electrocardiogram sensing device that can be attached to the user's wrist can be equipped to communicate with the service server 1000 through wireless communication methods such as 3G, LTE, LTE-A, WiFi, 4G, 5G, and Bluetooth.

When the user's electrocardiogram information is transmitted to the service server 1000 through this step, the electrocardiogram analysis unit 1500 can analyze whether the user was nervous after going to bat based on the results of analyzing the user's electrocardiogram, and furthermore, the user It can be equipped to analyze the health information of the cardiovascular system. Through this, the service server 1000 transmits information about whether the user is in a state of tension to an output device such as a projector that can output an image on a screen, allowing the user to directly check his or her state of tension or health. You can.

Next, a step is included in which the physical quantity analysis unit 1200 of the service server 1000 extracts the physical quantity information of the hit ball transmitted from the second image collection device (S120).

In this step, the image or video image collected by the second image collection device is analyzed to analyze the change in direction of the ball before and/or after the hit, the speed of the ball, the direction of the ball, and the amount of rotation of the ball.

For example, when a user hits a baseball by swinging a baseball bat, the physical quantity analysis unit 1200 detects a change in the direction of movement of the baseball, a change in the rotation amount of the baseball due to friction between the baseball and the baseball bat, Information on the physical quantity of the ball that can be used to generate analysis information about the speed of the baseball, etc. can be extracted.

In performing the above steps, the service server 1000 receives information about the user's motion image from the first image collection device and/or the second image collection device connected electrically or through a wireless communication method.

In addition, the first image collection device and the second image collection device may be equipped to collect video images or thermal images. In particular, when extracting the user's motion information, using a thermal camera that can detect the user's body temperature, etc. can help extract more accurate information about the user's movement. In addition, information about the user's physical condition can be conveyed, and training methods can be changed according to the physical condition.

For example, when the user's face is exposed, more accurate information about head movement can be collected by analyzing thermal images. In the case of various sports such as baseball, golf, soccer, and badminton that involve physical hitting of a ball, the movement of the user's head can help analyze the movement of the center of gravity and the resulting movement of the center of gravity.

Next, a step is included in which the motion analysis unit 1100 generates motion error information by comparing the coaching motion information stored in the data storage unit 1300 of the service server 1000 with the motion information (S130). The data storage unit 1300 may be provided to store a plurality of coaching motion information that can be compared and analyzed with the user's motion.

Meanwhile, the motion analysis unit 1100 may generate motion error information using the user's body information input through the data transmission/reception unit 1400 or the data input unit of the service server 1000. For this purpose, the coaching motion information is classified according to height, weight, body mass index, age, or gender, and the user's body information includes at least one of the information about height, weight, body mass index, age, and gender, and the motion analysis unit (1100) can generate motion error information by extracting coaching motion information from the data storage unit (1300) using the user's body information.

For example, coaching motion information can be provided in advance and compared with the user's motion information to select a coach whose information is closest to the user's height, weight, body mass index, age, and/or gender. . To this end, coaching motion information includes information on the height, weight, body mass index, age, or gender of the coach providing the coaching motion, so that the user and coach can be matched.

Additionally, the motion information may be transmitted from a center of gravity sensing device attached to the user's body or a step sensing device 100 that recognizes the user's step and generates the user's center of gravity movement information.

The center of gravity sensing device may include a gyro sensor, an image sensor, etc., and may be equipped to measure the movement of the center of gravity according to the user's movement. However, it is not limited to this, and is not limited to anything that can be attached to the user's body and measure the movement of the user's center of gravity.

It can be included.

The measurement control unit 130 determines whether it is necessary to stop the measurement of the sensing unit 120 based on information transmitted and input from the service server 1000. Specifically, when the event termination information that an event to stop foot stomping has occurred is transmitted from the service server 1000 to the measurement control unit 130, the measurement control unit 130 stops measuring the sensing unit 120, thereby eliminating unnecessary signals. Prevent unnecessary or unnecessary stamping behavior from occurring.

Meanwhile, the measurement control unit 130 may be equipped to control the sensing unit 120 to start operation when receiving a start signal requesting collection of the footfall information from the service server 1000. For example, when a user prepares to take off on a takeoff sensing device, unwanted takeoff information may be generated. Accurate measurement is made by excluding this unnecessary information and generating take-off information when actual take-off information needs to be initiated.

Figure 4 shows a system block diagram of the launch sensing device (second launch sensing device) 200.

The measurement control unit 220 measures the weight from the initial weight recognition point when the user makes an action, such as stepping on both feet and swinging a golf club or baseball bat, or stepping on one foot and kicking a soccer ball with the other foot, on the footfall sensing device. It can be equipped to obtain information about the flow of weight change up to the final recognition point. For this purpose, a sensor collects information about the first or last vibration after detecting vibration, detects changes in pressure due to stepping, or recognizes changes in the order of refraction or blocking of light when stepping. may be included individually or in combination.

The measurement control unit 230 determines whether it is necessary to stop the measurement of the measurement control unit 220 based on information transmitted and input from the service server 1000. Specifically, when the user's center of gravity movement information is measured through the measurement control unit 220 and the center of gravity movement information is transmitted to the service server 1000 through the data communication unit 110, the service server The batted ball final decision information is generated using the center of gravity movement information and image information received from the image sensing device. In other words, the swing is completed by moving the center of gravity and swinging the bat. If it is determined that a bat swing for hitting has been performed using the related image information, the measurement control unit 230 immediately or sequentially performs a bat swing using the measurement control unit 220. ) is controlled to start measurement.

Meanwhile, like the take-off sensing device, the measurement control unit may control the sensing unit to stop measuring when receiving batted ball final decision information from the service server 1000 through the data communication unit.

When the event termination information that an event to stop measuring weight movement has occurred is transmitted from the service server 1000 to the measurement control unit 230, the measurement control unit 230 stops measuring the sensing unit 220, thereby eliminating unnecessary signals. Prevent unnecessary or unnecessary stamping behavior from occurring.
