Description

Technical Field

[0001] This invention relates to the field of intelligent scoring in competitions, and in particular to an intelligent scoring method, scoring device, and system for martial arts competitions. Background Technology

[0002] Martial arts competitions include combat sports involving weapons or bare hands. The goal of the competition is to score more points than the opponent in order to defeat them or knock them down to end the match. At the same time, competitors must avoid the opponent's attacks to avoid affecting their combat effectiveness.

[0003] In martial arts competitions, scoring is based on a comprehensive evaluation of the striking point and the force of the strike. However, in current martial arts competitions, a competitor's score must be comprehensively evaluated by at least one referee. But when multiple participants compete simultaneously, the control and scoring of each venue is rather chaotic, making it difficult to grasp the overall scoring situation and obtain real-time information on the competition status of each session. Therefore, the current scoring method in martial arts competitions needs to be improved. Summary of the Invention

[0004] Therefore, in view of the problems existing in the scoring of martial arts competitions, the inventor proposes an intelligent scoring method, scoring device and system for martial arts competitions. Thus, the main purpose of the present invention is to provide an intelligent scoring method, scoring device and system for martial arts competitions that provides accurate scoring and scoring efficiency. The secondary purpose of the present invention is to provide an intelligent scoring method, scoring device and system for martial arts competitions that allows for real-time querying of the scores of both sides.

[0005] To achieve the above objectives, the intelligent scoring device for martial arts competitions provided by this invention employs the following technical means:

[0006] A scoring device for intelligent scoring in martial arts competitions includes: an electronic device with mobile communication and internet access capabilities, capable of connecting to the cloud for intelligent scoring, and pre-storing an application program in its memory unit, which is executed by its microprocessor unit, with the execution result output to its display unit; and a graphical interface displayed on the display unit and providing a graphical interface for operation by a real referee, including a graphical interface displaying the position of a strike, a strike image, a real score, a scoring suggestion, and a decision score for each round of the competition.

[0007] The graphical interface offers scoring suggestions in both automatic and manual modes, and the final score is determined by the actual scores of both teams.

[0008] The intelligent scoring device for martial arts competitions also includes a tournament referee program device, which provides at least one user interface for inputting match information for both sides. The tournament referee program device receives the hit signals sensed by at least two sensors, along with the hit area image, to obtain a hit area on the torso, and then uploads it to the cloud device in real time.

[0009] This invention provides a method for intelligent scoring in martial arts competitions, using the aforementioned scoring device. The method includes: a sensor-wearing step, where two sensors are provided for both competitors to wear; a strike step, where when the two sensors detect a strike, they wirelessly transmit the strike information to a referee program device; a strike image capture step, where multiple image capture devices identify the strike area in real time to determine the torso area struck, which is then transmitted in real time via a network to the referee program device located on-site, and subsequently uploaded to a cloud device; a cloud-based intelligent scoring step, where a scoring suggestion module on the cloud device provides a scoring suggestion, which is then transmitted to a scoring device within the referee program device; and a live referee confirmation step, where the scoring suggestion from the referee program device is confirmed by a live referee to obtain the actual score for the round, which is then transmitted back to the cloud device for viewing by spectators or competitors.

[0010] This invention provides an intelligent scoring system for martial arts competitions, constructed using the aforementioned intelligent scoring method. It comprises: at least two sensors, several image-capturing devices, a referee's procedure device, and a cloud device, all interconnected via a network. The at least two sensors are worn by both competitors and transmit strike signals to the referee's procedure device. The several image-capturing devices are installed around a ring area, recording video of both competitors and identifying the area of ​​a strike in real-time to determine the torso area hit, which is then transmitted to the referee's procedure device in real-time. The referee's procedure device includes... The system includes at least one user interface for inputting match information for both sides. The tournament referee program device receives the impact signals sensed by the at least two sensors, along with images of the impact area and the area of ​​the torso hit, and uploads them to the cloud device in real time. The cloud device is equipped with a scoring suggestion module, which makes scoring suggestions based on the dataset provided by the tournament referee program device. Finally, the scoring suggestions are transmitted to the tournament referee program device for confirmation by a live referee, and the actual score for this round is obtained. The confirmed actual score from the live referee is then transmitted back to the cloud device.

[0011] The intelligent scoring system for martial arts competitions includes a scoring suggestion module that obtains a usable model through machine learning. Specifically, a dataset and a training model are pre-established. The training model is trained using the dataset to obtain an evaluation model. If the evaluation model passes the verification, it becomes the usable model.

[0012] The intelligent scoring system for the martial arts competition includes data on the fields of the dataset, such as the "match number", the "suggested score" and "area of ​​impact on the torso" for both sides, and the "actual score" of the human referee.

[0013] The intelligent scoring system for the martial arts competition uses the data rows of "match number", "suggested score" for both sides and "area of ​​impact on the torso" from the dataset as features for prediction, and uses the data rows of "true score" from the dataset as labels to train the training model.

[0014] The intelligent scoring system for the martial arts competition uses a matrix factorization method to construct a scoring matrix based on the dataset. This matrix is ​​then input into the matrix factorization method, which outputs both displayed and implicit data. The displayed data represents the actual scores of both competitors.

[0015] The intelligent scoring system for the martial arts competition includes a handheld scoring device, which provides a real referee with the opportunity to confirm and monitor the scoring suggestions from the cloud-based device.

[0016] The intelligent scoring system for martial arts competitions includes at least two sensors, each mounted on the weapon or protective gear held by both competitors, making the intelligent scoring system applicable to competitions involving spear, fencing, combat, kickboxing, taekwondo, or bayonet techniques.

[0017] Accordingly, by employing the above-mentioned technical means, the present invention can achieve the following effects:

[0018] 1. In the course of a martial arts competition, this invention uses a sensor to trigger real-time video recording by several image-capturing devices, and simultaneously uploads the sensor information and hit images to a cloud device. The AI ​​referee (i.e., the image recognition and scoring module) built on the cloud device then makes a scoring suggestion and transmits it to the on-site referee device for confirmation and supervision by a human referee. Finally, the confirmed score is sent back to the cloud device to complete one round of the competition. All scores can be queried online in real time by the audience or the competitors, thus automating the scoring and improving the efficiency of martial arts competitions.

[0019] 2. The AI ​​referee (i.e., the image recognition and scoring module) set in the cloud device of the present invention can be supervised by a real referee to make scoring suggestions, and the more it is used, the more accurate the scoring suggestions will be. In addition, after the edge device pre-identifies the hitting areas of both sides of the game, the cloud performs intelligent scoring, which can reduce the threshold and cost of setting up cloud devices.

[0020] 3. All information about martial arts competitions in this invention, including match number, participating teams, scoring suggestions, hit images and their areas, is stored in this cloud device. In addition to being available for real-time query by spectators and athletes, it can also be used as a dataset for machine learning of AI referees, making it quite practical and convenient.

Detailed Implementation

[0033] First, please refer to Figure 1 As shown, the present invention provides an intelligent scoring method, scoring device, and system for martial arts competitions, applicable to intelligent scoring of competitions in spear, fencing, combat, taekwondo, or bayonet techniques. The intelligent scoring method A for martial arts competitions includes: a step of wearing a sensor in martial arts competitions, a step of hitting a target in martial arts competitions, a step of capturing the image of the target hit, a step of intelligent scoring in the cloud, and a step of confirming the score with a live referee, e. The aforementioned steps are explained below with reference to the figures.

[0034] The step a of wearing sensors in the martial arts competition is as follows: Figure 2 As shown, two sensors 1 are provided for both sides (red and blue) to wear in a martial arts competition; for example, in a martial arts spear competition, if... Figure 3 and Figure 4 As shown, the two sensors 1 are respectively installed in the gun head 61 of the large gun 6 held by the red and blue sides of the competition; if it is a combat competition, the two sensors 1 can be installed in the protective gear worn by the two sides of the competition. Such protective gear can be similar to the "Air Pressure Taekwondo Force Measurement Protective Gear Structure" in Taiwan Utility Model Patent No. M276194. Since such protective gear is very common on the market, it will not be described in detail in this invention.

[0035] In the martial arts competition's striking step b, when the two sensors 1 detect that one side has been struck, the sensors 1 wirelessly transmit the striking information to a referee procedure device 3 located on-site. Figure 5 As shown;

[0036] The image acquisition step c, as described above Figure 5As shown, several imaging devices 2 identify the area of ​​impact and the size of the torso hit in real time, and transmit the image to the tournament referee procedure device 3 in real time via the Wi-Fi network provided by the router modem. The tournament referee procedure device 3 then uploads the image to a cloud device 4. Furthermore, the several imaging devices 2 can capture a critical 8-second segment before the impact and upload it to the cloud device 4 via the tournament referee procedure device 3.

[0037] The cloud-based intelligent scoring step d is as follows: Figure 6 As shown, a scoring suggestion module 411 provided by the cloud device 4 makes scoring suggestions based on the dataset provided by the conference judging procedure device 3, and then the cloud device 4 transmits the scoring suggestions to the conference judging procedure device 3; furthermore, the scoring suggestion module 411 obtains a usage model 412 through machine learning, that is, a dataset 413 and a training model 414 are pre-established. The training model 414 is trained through the dataset 413 to obtain an evaluation model 415. If the evaluation model 415 passes the verification, it finally becomes the usage model 412.

[0038] Furthermore, such as Figure 7 As shown, the fields of dataset 413 further include data on the "number of matches", the "suggested scores" and "area of ​​impact on the torso" of both sides (red and blue), and the "actual score" of the human referee 34. The data rows of "number of matches", "suggested scores" and "area of ​​impact on the torso" of dataset 413 are selected as features for prediction, while the data rows of "actual score" of dataset 413 are selected as labels to train the training model 414.

[0039] Furthermore, the scoring suggestion module 411 is constructed using matrix factorization in conjunction with the dataset 413, such as... Figure 8 As shown, it is better to use the ML.net machine learning framework, that is, to construct a rating matrix A from the dataset 413, and then input the rating matrix A into the matrix factorization algorithm, which will output an explicit data V and an implicit data U. The explicit data V is the actual score of the two players in the game, and the implicit data U refers to the degree of interest of the user in the fields (items) of the dataset, which is reflected in the intensity of his / her above-mentioned behavior on the items: the number of games, the suggested scores of the two players, and the area of ​​the torso hit by the two players.

[0040] The aforementioned live referee confirmation scoring step e involves the live referee 34 confirming and supervising the scoring suggestion made by the tournament referee program device 3, obtaining the actual score for this round, and then transmitting the actual score of the live referee 34 back to the cloud device 4 for the audience or contestants to check.

[0041] Regarding the intelligent scoring system B for martial arts competitions of the present invention, it is used to execute the aforementioned intelligent scoring method A for martial arts competitions, such as... Figure 2 and Figure 5 As shown, it includes at least two sensors 1, several image acquisition devices 2, a conference referee procedure device 3, and a cloud device 4, etc., and can be interconnected via a router modem 32. The aforementioned components are described below with reference to the diagram.

[0042] The at least two sensors 1 are provided for both sides of the competition (red and blue sides) to wear, and provide to transmit hit signals to the referee procedure device 3 located on site. The at least two sensors 1 are respectively installed on the equipment or protective gear held by both sides of the competition. If a large gun 6 is used in this embodiment, the sensor 1 is installed on the gun head 61 at the front end of the large gun 6.

[0043] The imaging devices 2 are set up around the ring area 5 to record video of both sides of the match, and to identify the area of ​​the hit and the area of ​​the torso hit in real time, and transmit the video to the tournament referee program device 3 in real time. Furthermore, there are a total of 8 imaging devices 2, which are evenly arranged around the ring area 5.

[0044] The judging procedure device 3 of the conference includes at least a computer system with a preset program, a display device, and provides at least one user interface 31, such as... Figure 9 As shown, the user interface 31 provides input of the match information for both sides. The tournament referee program device 3 receives the hit signals sensed by the at least two sensors 1, along with the image of the hit area and the area of ​​the hit torso, and uploads them to the cloud device 4 in real time. Furthermore, the tournament referee program device 3 includes at least one handheld scoring device 33, which provides a live referee 34 to confirm and supervise the scoring suggestions of the cloud device 4 and obtain the real score for this round, thus providing the real score for both sides in this round of the match.

[0045] For further information, please refer to [link / reference]. Figure 10As shown, the handheld scoring device 33 can be a smartphone or an electronic device with a network connection and preset programs, i.e., an intelligent scoring system with mobile communication and internet access capabilities and the ability to connect to the cloud device 4. It has a memory unit that stores an application software, which is executed by a microprocessor unit. The result is output on a display screen. A graphical interface 331 is also provided on the display screen, which allows for operation by a real referee. The graphical interface includes a display of the hit position 332, hit image 333, actual score 334, scoring suggestion 335, and final score 336 for each round of the match. The scoring suggestion of the graphical interface 311 is further divided into automatic scoring mode and manual adjustment mode, and the final score 226 is further divided into the actual scores obtained by both sides of the match.

[0046] The cloud device 4 includes at least a server 41 and a database 42. The server 41 provides competition organizers with information on how to create competitions and is equipped with a scoring suggestion module 411. The scoring suggestion module 411 makes scoring suggestions based on the dataset provided by the competition's referee program device 3. Finally, the scoring suggestions are transmitted to the competition's referee program device 3 for confirmation by the live referee 34 to become the actual score. The confirmed actual score of the live referee 34 is then transmitted back to the cloud device 4 for real-time query by the audience or the contestants.

[0047] Therefore, this invention provides a preferred solution for an intelligent scoring method, scoring device, and system for martial arts competitions, such as... Figure 11 As shown, in a round of a martial arts competition, the present invention uses sensor 1 to trigger real-time video recording by several imaging devices 2, and simultaneously uploads the information and impact images from sensor 1, as well as the identified area of ​​the torso hit, to cloud device 4 via the tournament referee program device 3. The AI ​​referee (i.e., the scoring suggestion module 411) built on cloud device 4 then makes a scoring suggestion and transmits it to the tournament referee program device 3 for confirmation and supervision by the human referee 34, obtaining the actual score for this round. Finally, the confirmed score is sent back to cloud device 4 to complete one round of the competition and proceed to the next round. The competition ends only when both sides have reached the maximum score. All scores can be queried in real-time via the cloud network by spectators or competitors, thus automating scoring and improving the efficiency of martial arts competitions. Notably, the existing competition data stored on cloud device 4 can be used to create another dataset 413 to provide the scoring suggestion module 411 (i.e., the AI ​​referee) with machine learning to improve the accuracy of its scoring suggestions.
