[0036] The standard sampling rate is a sampling rate that can be recognized by the action learning model, and for a single sampling, the corresponding standard sampling rate is a single sampling rate.

[0037] Further, when the action judgment result is no collision, the adjudication module determines that the contestant has not violated the rules, and keeps the warning light green in response to the action judgment result.

[0038] Furthermore, when the action judgment result is a collision, the adjudication module determines that the contestant has committed a foul, the warning light is adjusted to red in response to the action judgment result, and the corresponding game image is uploaded to the visual device.

[0040] Furthermore, by setting up a target monitoring device to monitor and track the positions and movement trajectories of the contestants and the target football in real time, and taking pictures of the game images when the contestants and the target football are monitored at the same time, the locked shooting module provides a solid foundation for the automatic foul detection system in football matches based on deep learning, which can efficiently capture and transmit game images, provide high-quality data support for subsequent foul detection, and ensure the efficient operation and accurate judgment of the entire system.

[0054] A locking shooting module is used to lock the contestants and the target football. When the contestants and the target football appear at the same time, the locking shooting module shoots the game image;

[0055] A screening and processing module, which is connected to the locking and shooting module, is used to screen the game images and generate corresponding game information;

[0057] A decision module, which is connected to the action prediction module and is used to make a decision on the action judgment result. When the action judgment result is a collision, the decision module determines that the contestant has committed a foul. When the action judgment result is no collision, the decision module determines that the contestant has not committed a foul.

[0058] Among them, the action learning model is trained and generated based on the preliminary data of the game situation;

[0059] The result of the action judgment is the collision between the contestant's arm and the target football.

[0060] By setting a number of equally spaced decision devices, a single decision device includes: a locking shooting module, which is used to shoot a game image when a contestant and a target football appear at the same time; a screening processing module, which is used to generate corresponding game information; an action prediction module, which is used to select a number of learning features, pre-process the game information, and generate an action judgment result using an action learning model; a decision module, which is used to make a decision on the action judgment result; when the action judgment result is a collision, the decision module determines that the contestant has committed a foul; when the action judgment result is no collision, the decision module determines that the contestant has not committed a foul, thereby realizing automatic detection and judgment of foul behaviors, providing a more objective and accurate basis for judgment and penalty for football matches, reducing the interference of human factors, and improving the fairness and viewing of the game.

[0061] See also Figure 2 As shown, it is a structural schematic diagram of the locking shooting module of the present invention, including:

[0062] A target monitoring device, which is used to monitor and track the position and movement trajectory of the players and the target football in real time;

[0063] A camera connected to the target monitoring device is used to capture images of the game while monitoring the players and the target football at the same time;

[0064] The transmission device is connected to the camera and is used to store the game situation images and transmit the game situation images to the screening and processing module.

[0065] The target monitoring device is the core part of the lock-on shooting module, which is used to monitor and track the position and movement trajectory of the contestants and the target football in real time. It needs to have high precision and high real-time performance to ensure that the key moments in the game can be accurately captured. In specific implementation, the target monitoring device uses multiple image sensors to monitor the position of the contestants and the target football in real time through computer vision technology or target detection and tracking algorithms.

[0066] Object detection and tracking algorithms:

[0067] Use deep learning algorithms (such as YOLOv8) and adopt improved network structures (such as CSP structure and SPPF module) to improve the performance of the algorithm.

[0068] The camera is connected to the target monitoring device, and when it monitors the contestants and the target football at the same time, it captures the game image. In the specific implementation, the camera needs to have high resolution and high frame rate to capture clear images. The camera can flexibly capture the game scene by combining fixed and mobile perspectives. When the target monitoring device detects that the contestants and the football appear in the field of view at the same time, the camera is triggered to shoot. The camera can automatically adjust the shooting angle and focal length according to the position information provided by the target monitoring device to ensure that the best perspective is captured.

[0069] The transmission device is used to store the game images and transmit the image data to the screening and processing module. It needs to have the ability of high-speed transmission and large-capacity storage to ensure the real-time and integrity of the data.

[0070] In the specific implementation, a local server or cloud storage system is used to store the captured game images, support fast data reading and backup, and ensure the reliability of the system. High-speed transmission technology (such as 5G or UWB) is used to transmit image data to the screening and processing module in real time. The transmission device needs to have the characteristics of low latency and high bandwidth to meet the requirements of real-time processing.

[0071] By setting up a target monitoring device to monitor and track the position and movement trajectory of the participants and the target football in real time, and taking pictures of the game images when the participants and the target football are monitored at the same time, the locked shooting module provides a solid foundation for the automatic foul detection system in football matches based on deep learning. It can efficiently capture and transmit game images, provide high-quality data support for subsequent foul detection, and ensure the efficient operation and accurate judgment of the entire system.

[0072] See also Figure 3 As shown, it is a schematic diagram of the structure of the screening processing module of the present invention, including:

[0073] A filtering device, which is used to filter the game image using a pixel threshold to form a corresponding filtered image;

[0074] A cropping device, connected to the filtering device, for cropping the filtered image to a standard size;

[0075] An extraction device, connected to the cutting device, is used to extract the action features of the contestants and the position information of the target football, and generate corresponding game information;

[0076] The pixel threshold is the minimum standard for the pixels of the game image, and is related to the straight-line distance between the camera and the defense area of ​​the game field;

[0077] The standard size is the size that is suitable for the action learning model;

[0078] The motion features include the arm position information of the contestant, the relative position of the contestant's arm and the target football, and the extension direction and angle of the arm.

[0079] In the specific implementation, the pixel threshold is used to filter the game image to generate a filtered image. The pixel threshold is a key parameter and is the minimum standard for the pixels of the game image. It is related to the straight-line distance between the camera and the defensive area of ​​the playing field. The longer the distance, the higher the pixel threshold is required to ensure image quality. The pixel threshold is dynamically adjusted according to the actual distance between the camera and the field to adapt to different shooting conditions.

[0080] The cropping device is connected to the filtering device and is used to crop the filtered image to a standard size. The purpose of cropping is to adjust the image to a size suitable for subsequent processing and ensure that the cropped image can be correctly processed by the model.

[0081] The game image is filtered by the filtering device using pixel threshold, and the filtered image is cropped to a standard size, the action features of the contestants and the position information of the target football are extracted, the corresponding game information is generated, the effective information in the game image is screened, and the irrelevant content is removed to ensure that the cropped image can be correctly processed by the model, thereby realizing the analysis of the contestants' actions and the football's position.

[0082] See also Figure 4 As shown, it is a schematic diagram of the structure of the action prediction module of the present invention, including:

[0083] A selection device is used to select corresponding learning features according to the game information, wherein:

[0084] The learned features include the relative position and distance between the participant’s arm and the target football;

[0085] A preprocessing device, connected to the selection device, for preprocessing the game information and generating corresponding game pre-data;

[0086] The learning device is connected to the preprocessing device and is used to learn the pre-match data, generate corresponding action judgment results, and mark the action judgment results according to the learning characteristics.

[0087] The learning device generates prediction results of the contestants' actions by learning the pre-game data, and marks the action judgment results according to the learning characteristics for subsequent analysis and verification. In the specific implementation, the learning device analyzes the pre-game data based on machine learning algorithms (such as decision trees, support vector machines) or deep learning algorithms (such as convolutional neural networks, recurrent neural networks) and generates prediction results.

[0088] The relative position and relative distance between the contestant's arm and the target football are the key to motion prediction. The relative position can describe the geometric relationship between the contestant's arm and the target football, while the relative distance provides quantitative information.

[0089] By selecting features related to football interaction, preprocessing game information, and using a learning device to generate action judgment results, the complete process of feature selection, data preprocessing, and model learning lays the foundation for subsequent learning and judgment, provides reliable data input for the learning device, improves data quality and model learning efficiency, and helps to improve the accuracy of action judgment.

[0090] Specifically, the locking shooting module is provided with a single camera, and when the target monitoring device simultaneously monitors the contestants and the target football, a shooting instruction is issued to the camera;

[0091] Among them, the camera is facing the defense area.

[0092] Specifically, the filtering device obtains image pixels of the game image, wherein:

[0093] When the image pixel is greater than the pixel threshold, the corresponding game image is retained, and when the image pixel is less than the pixel threshold, the filtering device filters the corresponding game image.

[0094] In the specific implementation, the locked shooting module is equipped with a camera that faces the defensive area, ensuring that the camera can focus on the game situation in the defensive area, such as the players' defensive movements and interactions with the football.

[0095] The filtering device obtains the image pixels of the game image, that is, the resolution or pixel density of the image.

[0096] The role of pixel threshold:

[0097] Quality Control: Pixel threshold is used to ensure that the image quality meets the requirements of subsequent processing. Low-pixel images may contain too much noise or insufficient details, affecting subsequent feature extraction and analysis.

[0098] Relevance screening: Through pixel threshold screening, background images or blurred images that are not related to the game can be removed to improve the validity of the data.

[0099] The shooting is triggered by the target monitoring device, focusing on the key game situations in the defensive area. The filtering device filters the image through the pixel threshold to ensure that the image quality meets the requirements of subsequent processing. It not only improves the targeted image acquisition, but also reduces invalid data through the screening mechanism, providing a high-quality data foundation for subsequent image processing and analysis.

[0100] Specifically, the cropping device identifies the contestants and the target football and performs optimized protection, crops the filtered image to a standard size, and the extraction device extracts the standard coordinates of the contestants' arms and the target football based on the motion characteristics and position information, and integrates the standard coordinates into corresponding game information.

[0101] In a specific implementation, the function of the cropping device is to identify the contestants and the target football, and to crop the filtered image to a standard size. During this process, the cropping device will optimize the protection of key targets (contestants and target football) to ensure that the cropped image can meet the needs of subsequent processing. For example, using an object detection algorithm (such as YOLO) can achieve accurate identification of contestants and footballs, and determine the cropping area through a bounding box.

[0102] The extraction device extracts the standard coordinates of the players' arms and the target football based on the motion features and position information, and integrates these coordinates into the game information. This process can be achieved through deep learning models (such as YOLOv5, YOLOv8), which can identify key points in the image and extract relevant position information. For example, the YOLO model can detect the bounding boxes of players and footballs and further extract their coordinate information.

[0103] Specifically, the preprocessing device cuts the game information according to the standard sampling rate to generate a number of game pre-data with the standard sampling rate, and the action learning model learns the game pre-data and generates corresponding action judgment results;

[0104] The standard sampling rate is a sampling rate that can be recognized by the action learning model, and for a single sampling, the corresponding standard sampling rate is a single sampling rate.

[0105] In specific implementation, when the standard sampling rate is 1700 per second, the system has the best analysis effect on the game situation data.

[0106] The action learning model learns the pre-processed data of the competition and generates the corresponding action judgment results. This process can be achieved through machine learning or deep learning algorithms, such as support vector machines (SVM) or convolutional neural networks (CNN). By learning the pre-processed data, the model can determine whether the actions of the contestants meet specific rules.

[0107] Specifically, when the action judgment result is no collision, the adjudication module determines that the contestant has not violated the rules and keeps the warning light green in response to the action judgment result.

[0108] Specifically, when the action judgment result is a collision, the adjudication module determines that the contestant has committed a foul, the warning light is adjusted to red in response to the action judgment result, and the corresponding game image is uploaded to the visual device.

[0109] By learning the predicted match data and setting warning lights to display the action judgment results, the action judgment results are fed back in real time, and the color changes are used to intuitively show whether the participants have committed a foul. At the same time, the visual device is used to store and display key match images. It uses computer vision and machine learning technology to achieve real-time monitoring and judgment of the actions of participants in football matches. It can efficiently handle complex game scenes and provide auxiliary decision-making support for referees.

[0110] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.

For those skilled in the art, the present invention may have various modifications and variations.
