Description

Swing posture training method using golf simulation device

The present invention relates to a swing posture education method using a golf simulation device, and more specifically, in the swing practice through a golf simulation device, the device itself effectively compares and analyzes the movement of the expert without the help of a separate expert, and then related information It relates to a technology that effectively informs the self-diagnosis of the swing posture and how to improve the posture by providing.

As the standard of living has risen compared to the past, interest in golf is increasing. Therefore, a user who wants to learn golf for the first time learns from a swing posture. If there is time or money to spare, the user will receive an education about the posture through an expert and get immediate feedback on the wrong posture.

However, when 1:1 training by experts is difficult due to various reasons (financial burden, lack of time, burdensome training by experts, etc.), after learning educational videos related to swing posture through TV or the Internet, go to a golf driving range or screen golf course. You will practice swinging yourself in the same place.

In this way, if you practice swing yourself, it is difficult to identify the wrong posture yourself even if you review the swing posture of the expert in advance. In order to solve this problem, even if one's posture is photographed and checked through a camera, only approximate problems are identified, and it is difficult to accurately compare and analyze specific problems of the swing posture and the posture of an expert.

In this regard, we will look at techniques that can correct the swing motion without the help of an expert.

① In the registered patent No. 10-1893469 (golf swing exercise device for correcting the user's posture), the golf swing exercise device according to the present invention has a club connected to one side, and the user guides the club when the user takes a swing posture. An upper body correction government that corrects the upper body; A lower body correction unit that corrects the user's lower body when the user takes a swing posture; And a connection adjusting unit that connects the upper body correction unit and the lower body correction unit and adjusts the height of the upper body correction unit according to the height of the user.

The prior art is a technique in which repetitive practice is performed simply through a physical tool, and there is a problem in that it is impossible to receive an analysis according to an incorrect posture and feedback from an expert at all.

② In Patent No. 10-1889617 (a training system for analyzing and correcting golf swing posture), the present invention includes a wearer detachable from the user's clothing or body, a sensor unit detecting movement, and a received control signal. A plurality of motion sensing units including a first communication unit that is applied to the sensor unit and transmits a sensing signal from the sensor unit, and an interface unit that receives body information of a user and information on the wearing position of the motion sensing unit and outputs posture information and feedback information And, a reference setting unit that generates a reference value through a detection signal received through the first communication unit and body information and wearing position information input through the interface unit, and analyzes the pattern of the detection signal measured by the motion detection unit, and A determination unit that determines the start and end of a swing motion by comparison with a set pattern, a storage unit that classifies and stores the reference value and the sensing signal received through the first communication unit according to the wearing position, and the reference value and the swing motion. An analysis unit that analyzes a posture through a detection signal during a swing motion based on a start and an end to generate posture information and determines posture defect, and the interface unit generates correct posture feedback information when the analysis unit determines the posture defect. A technology including; a feedback unit outputting through the feedback unit is disclosed.

However, in the prior art, since the user who uses the practice system has the hassle of wearing a clothing for sensors that is not related to golf, and the swing position is measured only by a sensor installed on the clothing, the standard of the clothing and the physical condition of the user are changed. When they do not match, there is a problem in that the sensor is not accurately positioned on the user's body, and thus measurement accuracy is degraded. In addition, since the above technology does not consider the situation when the actual golf ball is hit, but simply analyzes and feedbacks with the swing posture, it cannot effectively inform the problems of the actual game.

The present invention was conceived to solve the above problems, and in measuring the swing posture of the user, it is made through the motion recognition method of the simulation device itself without wearing a separate sensor device, while the operation of the expert and the difference and It is an object to provide a swing posture education method using a golf simulation device that enables users to self-diagnose and improve their swing posture without the help of experts by clearly providing the solution part.

Furthermore, the present invention provides not only the comparison of the swing posture but also the trajectory information of the ball due to the wrong swing posture, thereby increasing the understanding of golf, establishing a posture correction goal, and directly experiencing the effects of posture correction. Another object is to provide a swing posture education method using a golf simulation device.

The present invention includes the steps of striking a golf ball through a golf simulation device, and simultaneously photographing a motion detection camera that detects a user's motion during the hitting process and a trajectory detection camera that detects the trajectory of the golf ball, and the motion detection Forming a joint point that connects the virtual skeletal line and the skeletal line according to the user's body from the image photographed through the camera, and comparing the skeletal line and joint point of the user with the skeletal line and joint point of a previously stored expert And analyzing and providing the analyzed information to a user.

In addition, the step of comparing and analyzing the skeletal line and the joint point; after passing through, analyzing the relationship between the trajectory information of the golf ball calculated through the trajectory detection camera and the swing posture information photographed through the motion detection camera; It is characterized by going through more.

In addition, in the step of analyzing the relationship, and then providing the analyzed information to the user, information is provided based on the trajectory of the golf ball caused by the swing posture as a result.

In addition, in the step of providing the analyzed information to the user; in the form of a user's posture as a virtual 3D character based on a virtual skeletal line and a joint point, it is characterized in that it is shown.

The present invention has the effect of enabling more accurate posture diagnosis by skeleting the user's posture through a golf simulation device and then comparing it with the posture of an expert, and it is possible to easily measure posture without wearing a separate sensing device. .

In addition, the present invention has the following effects when providing the relationship between the swing posture (cause) and the trajectory (result) of the golf ball together. First, beginners can improve their understanding of golf. Second, it can instill a goal to correct the wrong posture. Third, by directly experiencing the effect of improving the accuracy and distance obtained by correcting the wrong posture, it is possible to increase interest and further increase the reliability of the golf simulation device.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

The teaching method of the present invention relates to a technique capable of self-identifying and solving a problem of a swing posture through a golf simulation device without the help of a separate expert.

The present invention includes the step of striking a golf ball through a golf simulation device as shown in FIG. 1 (S-1), a motion detection camera for detecting a user's motion during the hitting process, and a trajectory for detecting the trajectory of the golf ball. Step of simultaneously photographing by the detection camera (S-2), and the step of forming a joint point connecting the virtual skeletal line and the skeletal line according to the user's body in the image captured by the motion detection camera (S-3) And, comparing and analyzing the skeleton line and joint point of the user with the skeleton line and joint point of the expert stored in advance (S-4), and providing the analyzed information to the user (S-5); It is characterized in that it is made.

The golf simulation device used in the present invention is a device in which a generally used golf ball, golf club, motion detection camera, trajectory detection camera, and light emitting device are installed. The motion detection camera is a device for analyzing a swing posture by detecting a user's motion, and is applied as an RGB camera and an IR camera. In addition, the trajectory detection camera is composed of a plurality of photographs of the traveling direction of the ball at different angles.

The trajectory analysis method of the ball through the trajectory detecting camera increases the number of light emitting devices (strobo devices) than the number of frames of the trajectory sensing camera, and thus multiple exposure images in which a number of balls are photographed as the number of flashes of the light emitting device in one frame image. After acquiring, analyze the motion of the ball and calculate the predicted trajectory with a computer program.

The step of hitting the golf ball (S-1) is a process of hitting the golf ball at a place other than an actual golf course using such a golf simulation device. Then, in the hitting process, a motion detection camera for detecting a user's motion and a trajectory detection camera for detecting a trajectory of a golf ball simultaneously photograph (S-2). This is to analyze the user's posture and the trajectory of the golf ball through each of these images.

In addition, the step of forming a joint point connecting the virtual skeletal line and the skeletal line (S-3) is to form a skeletal line and a joint point according to the user's body from the image captured by the motion detection camera through the program. do. The motion detection camera uses the principle of a Kinect sensor, and acquires depth information in pixels from an image captured by a combination of an RGB camera, an IR projector, and an IR camera, and based on the obtained depth information. By analyzing the characteristics of the pattern, it is possible to form a joint point connecting the virtual skeletal line and the skeletal line as shown in FIG. 2.

The skeletal line and the joint point are compared and analyzed (S-4) to determine the degree of similarity by comparing the skeletal line and the joint point of the user and the pre-stored expert with each other. The criterion to be determined in this way is to determine the degree of similarity by comparing the angle of the skeletal line, the position of the skeletal line and the joint point, and the change value of the skeletal line and joint point per frame. That is, the difference between the user and the expert corresponds to the problem of the swing posture that the user needs to correct.

In the step of comparing and analyzing the skeleton line and the joint point (S-4); frame synchronization between the user and the expert may be performed for a more accurate comparison. That is, there may be a difference between the user's swing speed and the expert's swing speed. If such a difference in swing speed occurs, and the same time and camera frame are used as a reference, a difference in motion occurs between the two, making it difficult to accurately compare. Accordingly, the point at which the swing starts and the point at which the swing ends are divided into one motion, and the point at which the swing starts and the point at which the swing ends regardless of the photographed time are divided and compared.

In addition, in order to further shorten the required time according to the analysis process, it is preferable to extract 30 images from the images captured in the swing motion process, and then compare them with the motions of the experts, rather than comparing all frames. In addition, when a user repeats an incorrect posture pattern, it is good to minimize the systemic load by making a database of related images so that they can be quickly found in the comparison and analysis process.

In the step of comparing and analyzing the skeletal line and the joint point (S-4); in order to obtain data related to the skeletal line and the joint point of the expert, it may be performed in two ways. First, the expert's swing posture is directly photographed with a motion-sensing camera to make it a skeleton, or second, based on the already known swing posture, the skeleton line and joint points are acquired in the form of forming the skeleton line and joint points to fit the camera frame in a computer program.

As described above, the step of comparing and analyzing the skeletal line and the joint point (S-4); when the analyzed information is provided to the user (S-5); it is finally notified to the user. . At this time, the notified information is alternately displayed on a separate monitor or screen so that the difference between the skeleton line and the joint point of the user and the expert can be checked.

In addition, analysis information related to the swing posture of the user and the expert may be informed by voice or text as follows. "Oo, you are in the chicken wing position of pulling the left shoulder during the shot process. The correct position is as follows." In other words, it informs the problem of posture first and shows the posture and differences of the expert.

3 shows another embodiment of the present invention, the step of comparing and analyzing the skeletal lines and joint points (S-4); after passing through, trajectory information and motion of a golf ball calculated through a trajectory detection camera It characterized in that it further passes through the step (S-4') of analyzing the relationship between the swing posture information photographed through the detection camera. The trajectory information of the golf ball refers to information related to the height, speed, and rotation direction of the ball.

In addition, the relationship between the trajectory information of the golf ball according to the swing posture may be analyzed based on the information stored in advance, but in order to further improve the accuracy, the data on the relationship between the swing posture and the golf ball trajectory may be analyzed by the user. The information obtained by using the simulation device can be continuously stored or updated. For example, if the chicken wing posture that corresponds to the wrong posture in which the left shoulder is lifted occurs during the swing process, it is possible to enter the relationship that causes the slice [Slice] in advance, but a certain trajectory of the ball may occur in a specific posture. In the case, this is also stored in the program as the relationship between the swing posture and the ball.

In the above embodiment, not only comparing the swing posture of the user and the expert, but also analyzing the relationship (S-4'); and providing the analyzed information to the user (S-5), the swing posture is determined. Information is provided based on the trajectory of the golf ball as the cause. In this way, if the relationship between the swing posture (cause) and the trajectory (result) of the golf ball is provided together, the following effects are obtained.

First, beginners can improve their understanding of golf. Second, it can instill a goal to correct the wrong posture. Third, by directly experiencing the effect of improving the accuracy and distance obtained by correcting the wrong posture, it is possible to increase interest and further increase the reliability of the golf simulation device.

In the step of providing the analyzed information to the user (S-5); as described above, analysis information related to the swing posture of the user and the expert may be informed by voice or text as follows. "OO, you are in the chicken wing position of pulling the left shoulder during the shot process. The correct position is as follows." Then the additional phrase "This swing position caused the slice to occur." This is to provide information to the user that the chicken wing posture causes the slice to occur.

In addition, in the step of providing the analyzed information to the user (S-5); the posture of the user based on the virtual skeletal line and the joint point may be superimposed on the actually photographed image as shown in the drawing. In the case of a virtual 3D character that is shown in the form of an expert's posture, it has the advantage of easy comparison between the expert and the user.

In the above, the present invention has been described with reference to the above embodiments, but it is of course possible to implement various modifications within the scope of the technical idea of the present invention.
