Method and device for providing customized curriculum according to evaluation results of taekwondo sparring using artificial intelligence

The present invention relates to a method and apparatus for providing a customized curriculum according to taekwondo sparring evaluation results using artificial intelligence, and more particularly, to a method for automatically providing a user's customized curriculum based on sparring evaluation results derived only from a user's sparring video and devices.

Taekwondo is a martial art that attacks or defends using hands and feet without weapons, and is a traditional martial art formed in modern times characterized by fast and powerful kicking techniques. It was adopted as a demonstration sport at the 1988 Summer Olympics and adopted as an official sport from the 2000 Summer Olympics.

Taekwondo can be largely divided into poomsae (type), gyeorugi (swealth), and breaking down (training), and Taekwondo, which was adopted as an Olympic event, is a sparring event, and the winner and loser are determined by scoring points through striking each other.

In order to accurately judge these sparring events, players attached sensors to the hitting hand or foot, and attached sensors to the target gear and protective gear to play the game.

However, due to erroneous judgments due to sensor errors, accurate judgments are becoming overshadowed, and due to the characteristics of the sensor system, which does not consider the strength of strikes, the original appearance of taekwondo sparring is also disappearing.

4 is a flow chart of a method for providing a customized curriculum according to evaluation results of taekwondo sparring using artificial intelligence according to an embodiment of the present invention.

Referring to FIG. 4 , in operation S410, an embodiment may obtain user training level information and sparring evaluation result information. For example, the sparring evaluation result information may include at least one of an accuracy item, a proficiency item, an expressiveness item, a skill diversity item, and an attack/defense item.

Here, the sparring evaluation result information may be derived from image information including the user's sparring movement. For example, the image information may represent information about a moving image or a plurality of still images. Alternatively, the image information may include a plurality of image information acquired at different times, and the order of the plurality of image information may be determined according to the order of time. The image information may include information about images of at least a part of a contest or an evaluation from start to finish.

For example, another embodiment may derive competition evaluation information from video information. In this case, another embodiment may derive skeleton information corresponding to the user's competition movement from image information using a pre-learned skeleton extraction model. Here, the skeleton extraction model can be learned through machine learning by configuring learning image information about motion and learning skeleton information corresponding to the learning image information as a learning data set, and various algorithms can be used for machine learning. In addition, another embodiment may determine at least one Taekwondo evaluation target motion among a plurality of Taekwondo motions based on the user's training level information, and the Taekwondo performed by the user among the plurality of Taekwondo motions based on the derived skeleton information. The performing motion may be determined, and based on the Taekwondo performing motion and the at least one Taekwondo evaluation target motion, it may be determined whether the user has performed at least part of the at least one Taekwondo evaluation target motion.

In operation S420, an embodiment may generate a user-customized curriculum based on the sparring evaluation result information. Here, the customized curriculum may be created based on numerical values and training level information corresponding to at least one item.

In one embodiment, in the case of Taekwondo, the basic curriculum may be different depending on the training level. After deriving a basic curriculum suitable for the user's training level, a customized curriculum is created by reflecting the user's evaluation result information in the derived basic curriculum. can do. In other words, in an embodiment, when the user's training level is 1st class, the user's competition evaluation result information may be used to correct the basic curriculum corresponding to 1st class, and when the user's training level is 2nd class, the user's competition evaluation result information may be corrected. The basic curriculum corresponding to the second grade can be corrected using the evaluation result information. At this time, the basic curriculum corresponding to the first grade and the basic curriculum corresponding to the second grade may differ from each other in the types of included motions and/or the number of times performed. can be different.

In more detail, the customized curriculum according to an embodiment may be generated by correcting the number of exercises for each action in the basic curriculum related to sparring corresponding to training level information based on a numerical value corresponding to at least one item.

For example, accuracy items, proficiency items, expressiveness items, skill diversity items, and attack/defense items, respectively, can be included in the competition evaluation result information with corresponding figures, and these figures and the reference values of each item are compared to practice for each action. Count can be corrected.

For example, the correction may be primarily performed on an operation related to an item in which the numerical value of each item does not meet the standard value for each item among the operations included in the basic curriculum, and the competition evaluation result among the operations included in the basic curriculum It may be performed secondarily with respect to an operation related to an item having the lowest numerical value among items included in the information.

For example, the accuracy item may be determined based on a difference between a hitting target point of an operation performed by a user and a hitting point actually hit by the user, and the smaller the difference, the higher the accuracy item may be determined.

For example, the skill item may include at least one of distance control information, force intensity information, and motion continuity information. For example, proficiency information may be determined according to different ratios or weights among distance control information, force strength information, and motion continuity information, but may be determined with the same ratio or weight. These ratios or weights may vary according to settings and may be automatically changed according to the level of training.

For example, the expressiveness item may include at least one of spirit information and creative skill information. For example, the spirit information may be derived from audio information corresponding to the video information, and the creative technique information relates to a user's creative competition movement rather than a plurality of previously set Taekwondo movements, and the evaluation committee terminal connected through a network in advance can be obtained through

For example, the item of skill diversity may be determined higher as the number of types of motion performed by the user increases, and may be determined higher as the difference in the number of times for each motion decreases. In addition, although the diversity information of techniques used may be determined only by motions to be evaluated in Taekwondo, the diversity information of techniques in use may be determined by considering not only motions to be evaluated in Taekwondo but also a plurality of Taekwondo motions in terms of technology utilization.

For example, the attack/defense item may indicate attack/defense ratio information, and may be determined based on a Taekwondo performance performed by the user. For example, the attack/defense ratio information may be determined based on the number of offensive motions and the number of defensive motions, which is calculated or judged based on information on the type of motion corresponding to the user's Taekwondo performing motion among a plurality of taekwondo motions. It can be.

Alternatively, for example, the sparring evaluation result information may include first sparring evaluation result information corresponding to a first time point and second sparring evaluation result information corresponding to a second time point prior to the first time point, in this case The number of exercises for each action in the sparring-related basic curriculum is based on a numerical value corresponding to at least one item included in the first sparring evaluation result information and a numerical value corresponding to at least one item included in the second sparring evaluation result information. It may be corrected using the determined correction weight.

For example, a difference between the value of a specific item included in the first competition evaluation result information and the value of a specific item included in the second competition evaluation result information is less than a threshold or included in the first competition evaluation result information If the numerical value of the specific item is lower than the numerical value of the specific item included in the second sparring evaluation result information, it is determined that the user is not improving at all with respect to the specific item, and a correction weight for a motion related to the specific item is set high. can

Here, the correction weight may be applied to the above-described primarily performed correction. That is, if an item having a numerical value less than the reference value is a specific item that is not improved as described above, when correction is primarily performed, the number of related operations may be more increased than other items to be corrected.

Alternatively, for example, an embodiment may create a customized curriculum in which the total number of operations of the customized curriculum and the total number of operations of the basic curriculum are the same. That is, when there exists an action in which the number of times for each action increases according to the sparring evaluation result information, there may be an action in which the number of times per action decreases. To this end, in one embodiment, correction may be performed based on the ratio of the number of operations of the basic curriculum, and the number of times for each operation of the final customized curriculum may be determined based on the corrected ratio of the number of times.

Or, for example, a customized curriculum may further include information on training methods in addition to information on various motions. For example, the training method relates to how to train for a specific motion, how to perform the motion with a specific weight, how to perform the motion alone, how to perform the motion with the other person, and a specific tool It may include a method of performing an operation using. The customized curriculum may select and provide a training method of motion related to the corresponding item from among a plurality of methods based on the numerical value of at least one item included in the competition evaluation result information, and based on the user's body information and numerical value It can also be provided by determining the weight and tool.

Alternatively, for example, the customized curriculum may further include information on competition strategies in addition to information on various movements. For example, as the sparring strategy, at least one of a plurality of preset strategies may be selected and provided based on an operation related to an item having the highest value among at least one item included in the sparring evaluation result information.

In operation S430, an embodiment may provide information about a customized curriculum to a user terminal corresponding to a user. For example, a customized curriculum may be created by determining different operations depending on the number of days of training, and in one embodiment, the entire customized curriculum may be provided to the user through a user terminal, and a customized curriculum of one day suitable for the number of days to be performed may be provided to the user. It may be provided to the user through the terminal.
