Description

Technical Field

[0001] The present invention relates to the technical field of electronic assisted refereeing, and in particular to an electronic assisted refereeing method, device, equipment and medium for competitive egg-throwing competitions. Background Art

[0002] In offline competitive doudan competitions, four players sit on the east, south, west, and north sides of the table, divided into two teams, one for the east and west, and one for the south and north. A baffle is set diagonally above the table, with the north and east players on one side and the south and west players on the other. A window is set below the center of the baffle. The baffle is at least 40 cm longer than the tabletop diagonal (that is, at least 20 cm on each side) and 80 cm high. The window is 60 cm long and 15 cm high.

[0003] However, the current refereeing method for offline competitive egg-throwing competitions has the following main disadvantages:

[0004] Disadvantage 1: During the competition, athletes often forget to report violations, which affects the progress of the game and requires a lot of intervention from referees. In addition, the regulations on reporting in offline competitions are inconsistent with the reporting procedures of online throwing egg software, which is not conducive to the promotion and popularization of throwing egg sports.

[0005] Disadvantage 2: Because the rules of competitive throwing egg games are relatively detailed and complicated, it is necessary to always pay attention to whether athletes have violated the rules. Referees are often required to intervene, which on the one hand increases the workload of referees, and on the other hand lacks the technical means to analyze and handle disputes when they arise.

[0006] Disadvantage 3: Offline games are usually held on a card table. However, a window needs to be set up in the center of the diagonal baffle to facilitate mutual viewing of the opposite card area, which also brings the risk of teammates passing signals to each other through gestures, card placement, etc. In order to avoid such violations, some offline games arrange two referees at each table, and the referees place the cards on the card table instead of the players. This greatly increases the workload and cost of the game, which is not conducive to the promotion of competitive egg-throwing games.

[0007] At present, there are reports that image recognition technology is used to identify cards in some card games, but these card recognition technologies have the following two defects:

[0008] 1. After the timing starts, it is necessary to collect images and recognize the cards through the camera in real time and continuously, which greatly increases the computing power.

[0009] 2. They are all based on a single background, and it is impossible to identify the situation of the second card after two cards are played. Otherwise, the card surface of the previous card will be added to the card surface of the second card, causing confusion. The "Competitive Egg Throwing Competition Rules (Trial)" clearly requires the way of playing cards: each card played must be placed in the card-playing area of ​​the family; after a round of cards is over, the cards in the card-playing area are placed face down in the family's discarding area in order, and no athlete is allowed to view them. The "Competitive Egg Throwing Competition Rules (Trial)" clearly states: A round of cards: a process in which four athletes play cards in order and suppress them step by step. Some people can not play cards in a round of cards. When three consecutive people pass cards without playing, the round ends. It can be seen that the egg throwing competition requires the situation of the second card to be identified after two cards are played. Summary of the invention

[0010] The technical problem to be solved by the present invention is to provide an electronic assisted refereeing method, device, equipment and medium for competitive throwing egg competitions, which assists in the refereeing of throwing egg competitions based on machine vision technology. Players on both sides of the baffle can view the opponent's redrawn cards through the display screen, which greatly reduces the risk of cheating by passing secret signals to each other. It can not only make the refereeing more scientific and fair, but also greatly save labor costs.

[0011] In a first aspect, the present invention provides an electronic assistant referee method for a competitive egg-throwing game, including an assistant referee process for playing cards, wherein the assistant referee process for playing cards includes:

[0012] S11, when a player's card-playing timer starts, control the camera to capture the initial image of the current player's card-playing area as the background image;

[0013] S12, using a camera to detect in real time whether there is an object intrusion into the card-discharging area, and if so, collecting a new image of the card-discharging area after the object intrusion ends;

[0014] S13, performing image difference processing on the new image and the background image to obtain a difference area;

[0015] S14, calling a card recognition model to recognize the card faces in the differential area, including numbers, suits, and the number of cards corresponding to each number and suit;

[0016] S15, redrawing the playing card image according to standardized display rules;

[0017] S16. The redrawn playing card image is displayed to the player on the other side of the isolation baffle through the display screen, and the card-playing timer ends. Then, the card-playing timer of the next player is started, and the number of remaining cards is calculated and recorded according to the current number of played cards.

[0018] In a second aspect, the present invention provides an electronic auxiliary referee device for a competitive egg-throwing game, comprising:

[0019] The background image acquisition module is used to control the camera to collect the initial image of the current player's card-playing area as the background image after the timing of a player's card-playing starts;

[0020] The intrusion detection module is used to detect in real time through the camera whether there is an object intrusion in the card-discharging area. If so, a new image of the card-discharging area is collected after the intrusion of the object ends;

[0021] A difference processing module, used for performing image difference processing on the new image and the background image to obtain a difference area;

[0022] A card recognition module, used to call a card recognition model to recognize the card faces in the differential area, including numbers, suits, and the number of cards corresponding to each number and suit;

[0023] A redrawing module, used for redrawing the playing card image according to standardized display rules;

[0024] A display module, used for displaying the redrawn playing card image to the players on the other side of the isolation baffle through a display screen;

[0025] The counting module is used to calculate and record the number of remaining cards based on the current number of cards played when the card playing timer ends;

[0026] The timing module is used to start or end the player's card-playing timing.

[0027] In a third aspect, the present invention provides an electronic device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the method described in the first aspect when executing the program.

[0028] In a fourth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method described in the first aspect.

[0029] One or more technical solutions provided by the present invention have at least the following technical effects or advantages:

[0030] 1) Through display image acquisition, recognition, redrawing and display, the necessary information of each player when playing cards is accurately displayed to the other party through electronic assistance, while hiding unnecessary information. Therefore, the window in the lower center of the baffle on the table can be closed during the card-playing process, eliminating the risk of transmitting illegal information between teammates and enhancing the fairness of the game.

[0031] 2) Card recognition only requires collecting an image of the card-playing area as the background image in combination with the timing starting point, and combining the end moment of judging the intrusion of the object as the time point for collecting the card face image. The newly added area is obtained through differential processing, and the card face recognition model can be called to identify the card face in the differential area. Whether it is the first time or the second time, the card face of each card can be successfully identified without any misunderstanding, and the computing power of the system is greatly saved.

[0032] 3) After card recognition, card type judgment is added to further determine whether the card is in compliance with the rules, further liberating manpower and enhancing the fairness of the game.

[0033] 4) It can accurately and automatically time, enhance the compactness of competitive throwing egg games, and accurately record the number of cards in the hands of the players, supervise the players to report the number of remaining cards according to the rules, or directly let the system notify other players of the number of remaining cards, so that the players can return their energy to the game itself.

[0034] 5) The competition process can be stored digitally and can be traced back as evidence when violations or disputes occur.

[0035] 6) It is conducive to the live broadcast of the event. The video resources on both sides of the partition can be integrated to form a bird's-eye view video of the entire card table for live broadcast of the event.

[0036] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented according to the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are listed below.

[0046] The embodiment of the present application provides a method for assisting the refereeing of a throwing game based on machine vision technology, which not only enables refereeing to be more scientific and fair, but also greatly saves labor costs.

[0047] The technical solution in the embodiment of the present application has the following general idea: by displaying image acquisition, recognition, redrawing and displaying, the necessary information of each player when playing cards is accurately displayed to the other party through electronic assistance, while hiding unnecessary information, so that the window in the lower center of the baffle on the table can be closed during the playing process, eliminating the risk of transmitting illegal information between teammates and enhancing the fairness and justice of the game. After combined with differential processing, card recognition only needs to identify the newly added area after the difference of the two images, which greatly saves the computing power of the system, and whether it is the first time to play cards or the second time to play cards, the cards played each time can be smoothly identified without misrecognition. In addition, the card type judgment model can also be combined to judge the card type of the identified card face, and further judge whether the current card is illegal, which greatly saves the manpower and time costs of the referee.

[0048] Before introducing the specific embodiments, the table structure of the competitive egg-throwing game adopted in the embodiments of the present application is first introduced. Figure 1 As shown, the card table for the competitive egg-throwing competition adopted in the embodiment of the present application includes: a desktop 1, an isolation baffle 2, two cameras 3 and two display screens 4.

[0058] S01, collect a large amount of playing card image data, including single playing card, multiple playing cards, multiple playing cards stacked but with numbers and suits exposed, pure color background and various complex backgrounds, and different lighting conditions, to obtain a playing card data set;

[0059] S02. Manually label the poker data set, and divide the poker cards into 54 categories, including four-suit AK and big and small jokers; merge the training sets of various PASS cards (pass cards) to obtain the PASS category as the 55th category;

[0060] S03, randomly group the merged data set into training set and test set according to 8:2, unify the width and height of all pictures, and randomly add rotation and scaling to a small part of the pictures;

[0061] S04. Use YoloV5 deep learning algorithm to train the training set, and verify the test set based on the model. After verification, the card recognition model is obtained.

[0062] S15, redrawing the playing card image according to the standardized display rules; wherein, this embodiment may also include card type judgment: that is, the S15 is replaced by: calling the card type judgment model to judge the card type of all card combinations in the differential area, and obtaining the card type result corresponding to the current card; judging whether the current card is in compliance with the rules of the competitive throwing egg competition and the card type result according to the competitive throwing egg competition rules, if so, redrawing the playing card image according to the standardized display rules; if not, returning to S13, re-performing image difference processing, card recognition and card type judgment, if the card type judgment result is still not in compliance with the throwing egg card type rule after repeating the preset number of times, a warning is issued;

[0063] like Figure 3 As shown, the process of the card type judgment model for card type judgment includes: the process of the card type judgment model for card type judgment includes: first judge whether the number of combinations of all cards is single, two, three or more than four; if it is a single card, it is judged as a single card type; if it is two, then judge whether the numbers or points of the two cards are the same, if so, it is judged as a pair card type, otherwise it is considered to be an illegal card type; if it is three, then judge whether the numbers or points of the three cards are the same, if they are the same, it is judged as a three-same card type, otherwise it is considered to be an illegal card type; if it is four (inclusive) or more, then judge whether the numbers or points of the cards are the same, if so, it is judged as a bomb card type, if not, combine the number to determine whether it contains four big and small kings, whether it is a continuous number of points, whether it is the same suit, whether the number and size of the same points meet the card types such as three-pair card type, three consecutive pairs or three same consecutive cards, if so, it is judged as the corresponding card type, if not, it is judged as an illegal card type.

[0064] S16. The redrawn playing card image is displayed to the player on the other side of the isolation baffle through the display screen, and the card-playing timer ends. Then, the card-playing timer of the next player is started, and the number of remaining cards is calculated and recorded according to the current number of played cards.

[0065] First, the initial number of playing cards in each player's hand is fixed at 27. During the game, machine vision can be used to determine the number of cards that have been played in each deck of cards, and the number of cards remaining in the player's hand can be calculated. Calculating the number of remaining cards can remind players to report the number of remaining cards according to the rules under the specified number of cards, or directly let the system notify other players of the number of remaining cards. For example, when a player's remaining number of cards is ≤10, notify other players of the number of remaining cards.
