Description

Analysis and evaluation apparatus for each detailed item related to Taekwondo movement}

The present invention relates to an analysis and evaluation device for each detailed item related to Taekwondo movements for Taekwondo Poomsae evaluation.

Taekwondo is the national flag of Korea, and Kukkiwon has total jurisdiction over the world's Taekwondo promotions and promotions. Screening refers to the procedure for Taekwondo practitioners to acquire Kukkiwon Taekwondo promotion and promotion qualifications. According to Kukkiwon's Taekwondo screening operation rules, factors such as "line of sight, spirit, speed, strength, stretch, center of gravity, posture, variety of energy, distance adjustment, etc. are evaluated as a passing criterion of 60 points or more.

On the other hand, in the case of promotion and promotion screening, it is conducted in real time in front of the judge whether the evaluation target performs the movement accurately. The promotion evaluation and promotion evaluation is an absolute evaluation rather than a relative evaluation, and it is evaluated whether the applicant's skills in Poomsae or Gyorugi are above a certain level.

Taekwondo Poomsae refers to movements in which attack and defense techniques are linked in a prescribed format so that they can be practiced without a leader. Through Poomsae, trainees can improve their fighting skills, apply movements, and develop special skills that cannot be learned in basic movements.

In general, Poomsae is practiced according to the Poomsae line, which indicates the position of the feet and the direction of their movement, and there are 10 types: Taegeuk, Goryeo, Geumgang, Taebaek, Pyeongwon, Sipjin, Jitae, Cheonkwon, Hansu, and Ilyeo. In the conventional Poomsae reading method, judges sit in their seats and determine the winner by summing the points scored by subjective judgment. However, the conventional Poomsae reading method inevitably relies on the subjectivity of the evaluator, resulting in poor scoring accuracy and fairness, and inevitably causing disputes in the judgment of judges due to prejudice or errors of judges.

In other words, although the continuous motion of the subject of evaluation proceeds for a long time, the examiner evaluates the subjective motion of the subject subjectively from the overall perspective, so a problem of fairness inevitably arises, and the continuous motion of the subject of evaluation continues even after the examination is over. There was a problem that it was impossible to determine how this was done and which motion was performed properly or insufficiently.

For example, the server 100 according to an embodiment may provide a list of screening motions for a specific Poomsae performed by the evaluation target to the judge terminal 300 corresponding to the evaluation target while the evaluation target performs the specific Poomsae. In addition, the judges can check the motions performed by the evaluation target and proceed with the evaluation through the judges terminal 300 immediately based on the evaluation motion list. Here, in one embodiment, an image may be obtained and stored through the photographing device 200 interlocked in advance with respect to a specific Poomsae performed by an evaluation subject. These images can be provided in the event of an objection later, and can be used as evidence for a fair evaluation.

The judge terminal 300 may be one or more according to the number of judges, but in the specification of the present invention, it will be treated as a singular number for convenience of description. However, even if the judges' terminals are treated as a singular number in the description, the fact that a plurality of judges' terminals are used does not deviate from the scope of the present invention.

Taekwondo Poomsae can be composed of continuous movements in which a plurality of unit movements are continuously performed at short time intervals. Depending on the change of , it can be distinguished into different unit operations. In other words, Taekwondo Poomsae can be composed of continuous unit movements, and accordingly, unit movements can be classified according to various criteria. Here, the criterion may be determined by the user as needed, and may be a criterion for subdividing into minimum units of motions that are not divided any more when the technique of taekwondo is normally disassembled.

According to an embodiment, the server 100 may analyze a specific poomsae of an evaluation target based on evaluation information corresponding to a list of evaluation motions obtained from the judge terminal 300, and may derive evaluation results. . Here, the review operation list may be provided by being divided into subdivided detailed items, and the detailed items may be provided according to the order of operations.

Through this, the judges can easily and quickly proceed with the evaluation in order immediately after seeing the movements performed by the evaluation target in order.

4 is a diagram showing analysis information according to evaluation results of Taekwondo motions according to an embodiment of the present invention.

Referring to FIG. 4 , analysis information according to an embodiment may be derived based on evaluation information obtained from the judge terminal described in FIG. 3 .

For example, the analysis information may derive the number of motions for each detailed item, the total number of motions that serve as standards for each detailed item, the number of motions correctly performed by the subject of evaluation, and the motions not performed by the subject of evaluation. The number of can be derived. In other words, the analysis information is information on the number of total motions for each of the detailed items (descriptive motion in FIG. 4) and information on the number of motions performed by the evaluation target for each of the detailed items (correct motion in FIG. 4). and information on the number of operations that the evaluation target failed to perform for each of the detailed items (deficient operations in FIG. 4).

In addition, the lack of motion included in the analysis information is information on the number of motions corresponding to the left direction that the evaluation subject did not perform for each of the detailed items, and corresponding to the forward direction that the evaluation subject did not perform for each of the detailed items. Information on the number of motions performed and information on the number of motions corresponding to the right direction that the evaluation subject did not perform for each of the detailed items may be further included. That is, the specific postures described in each detailed item of the judges motion list are described whether they are in the right direction, left direction, or square, and together with this, based on the information evaluated by the judges, right, forward, and left Analysis information can be derived by dividing the direction.

Furthermore, when the number of insufficient motions is described as 1 or more according to the direction, the name of the specific posture that the evaluation subject failed to perform may be identified by selecting the corresponding number. That is, when the number of motions that the evaluation subject failed to perform for each of the detailed items is 1 or more, the analysis information includes name information indicating an operation corresponding to the left direction that the evaluation subject in the evaluation motion list failed to perform, the At least one of name information indicating an action corresponding to the forward direction not performed by the evaluation target in the evaluation action list and name information indicating an action corresponding to the right direction not performed by the evaluation target in the evaluation action list You may.

According to an embodiment, the ratio of correctly performed motions may be derived based on the number of total motions and the number of motions correctly performed by the evaluation target based on the evaluation information, and the number of motions performed correctly by the evaluation target for a specific Poomsae based on the ratio can decide whether or not to pass the examination. However, in one embodiment, an evaluation score may be separately derived based on a weight to be described later, and based on this, it may be determined whether or not the evaluation target passes the screening.

5 is a flow chart of a Taekwondo motion screening method according to an embodiment of the present invention.

Referring to FIG. 5 , in one embodiment, information on a specific Poomsae may be obtained from the judges terminal (S510). Here, the specific Poomsae may be information indicating a specific Poomsae such as Taegeuk 7, but is not limited thereto.

In one embodiment, an evaluation action list corresponding to a specific Poomsae may be derived and provided to the judge terminal (S520). Here, the screening motion list may include detailed items for each motion order in which the continuous unit motion corresponding to the specific Poomsae is subdivided according to a predetermined criterion, and the detailed items are the next item, the direction movement item, the writing item, and the handwriting item. items may be included. In more detail, it has been described above together with FIG. 3 .

In one embodiment, evaluation information on detailed items for each action order in the evaluation action list may be acquired from the judges terminal (S530). For example, in one embodiment, only from the first time point when the evaluation target starts the motion corresponding to the specific Poomsae to the second time point when the evaluation subject ends the motion corresponding to the specific Poomsae, Evaluation information may also be acquired. Here, the first point of view may indicate a point of time when the first time has elapsed when it is determined that the evaluation subject is continuously located in an image corresponding to a pre-specified area for a first preset time, and the second When it is determined that the evaluation subject is not continuously located in the image for a preset second time period, the time point may indicate a time point at which the second time period has elapsed.

Alternatively, for example, although not shown in FIG. 5, in one embodiment, an image of a pre-designated area may be obtained through a pre-interlocked photographing device, and through the image, it is possible to determine whether an evaluation target has started an action for a specific poomsae or It may be determined whether the operation has ended, and the evaluation action list may be provided to the judges' terminals only during the period according to the determination.

In addition, in one embodiment, authentication of the subject of evaluation may be performed through a pre-interlocked photographing device. That is, in an embodiment, it is possible to determine whether an evaluation subject performing a motion for a specific Poomsae within an image is a correct evaluation subject by comparing pre-stored first face information of the evaluation subject with second face information of the evaluation subject included in the image. can In this case, in one embodiment, when the matching rate between the first face information and the second face information is greater than or equal to a threshold value, it may be determined as a correct evaluation target. An embodiment may use a face recognition algorithm for this purpose, and in some cases, a machine learning model using various algorithms may be used. However, since the face recognition algorithm is a well-known technology, a detailed description thereof will be omitted.

According to an embodiment, motions of the subject of evaluation performing a specific Poomsae may be additionally acquired and stored as a video, and the timing of the video may be a first point in time when it is determined that the subject of evaluation has started a motion for a specific Poomsae, and the end It may be a second point in time when it is determined that the evaluation target has finished the motion for a specific Poomsae.

In addition, the first time may be a time when identity authentication is performed through the above-described face recognition, and a video corresponding to the first time may be additionally acquired and matched with a video of the operation of performing Poomsae and stored. In this case, a video corresponding to the first time may be referred to as a first video, and a video of an operation of performing Poomsae may be referred to as a second video.

When the first video and the second video are stored together, the first video is for user authentication and may be stored in a relatively high first resolution, and the second video is for motions related to Poomsae and has a relatively high resolution. It can be stored as a second resolution with a lower resolution. This may be to prevent unnecessarily excessive capacity being allocated when all videos are stored in the first resolution. That is, one embodiment can obtain and store each video most efficiently according to the purpose.

One embodiment may derive analysis information on the evaluation target based on the evaluation information (S540). For example, an embodiment may derive weights for each of the detailed items for each operation order in the screening action list, and based on evaluation information and the weights for the detailed items for each operation order in the screening action list, the weights are determined. An evaluation score for the evaluation target may be calculated, and based on the evaluation score, information on whether the evaluation target for the specific Poomsae passes the examination may be determined.

More specifically, an embodiment may calculate a failure probability for each of the detailed items for each action sequence based on past evaluation information of a plurality of other evaluation subjects for the specific Poomsae, and based on the failure probability First partial weights for each of the detailed items for each operation order can be derived. In addition, an embodiment may obtain difficulty information for each of the detailed items for each operation order from a plurality of other judges terminals for the specific Poomsae, and each of the detailed items for each operation order based on the difficulty information. Second partial weights may be derived for , and weights for each of the detailed items for each operation sequence may be determined based on the first partial weights and the second partial weights.

An embodiment may provide analysis information to an evaluation target terminal corresponding to an evaluation target (S550). Here, the analysis information is information on whether or not the evaluation target for the specific Poomsae passed the examination, information on the total number of motions for each of the detailed items, and information on the number of motions performed by the evaluation target for each of the detailed items. It may include information and information on the number of operations that the evaluation subject failed to perform for each of the detailed items. A detailed description of the analysis information has been described above along with FIG. 4 .

In addition, in an embodiment, when a first objection request is received from an evaluation target terminal, a review action list and evaluation information corresponding thereto may be provided to the evaluation target terminal. In addition, in an embodiment, when a second objection request is received from the evaluation target terminal after the first objection raising request, the first video and the second video may be provided to the evaluation target terminal. However, in this case, image information including facial information of the subject of evaluation is first obtained from the terminal to be evaluated, and it is determined whether the date information included in the image information is the current date. If the matching rate is greater than or equal to a threshold value by comparing face information (the above-described first face information), the first video and the second video may be provided. Since this is an image in which the face of the subject for evaluation is exposed as it is, it may be a method of strengthening security.
