Description

Background Art

[0002] Existing volleyball action scoring systems can, to a certain extent, objectively evaluate the skill levels of athletes (including students, trainees of various clubs, junior volleyball players, and volleyball enthusiasts). However, there are also some drawbacks, mainly including the following aspects:

[0003] I. Uniformity and Subjectivity of Scoring Criteria

[0004] Insufficient Standard Uniformity:

[0005] Due to different technical capabilities and volleyball experiences of scorers, there may be differences in the scoring criteria for volleyball actions. There may be ambiguous areas in the formulation and implementation of the criteria, resulting in a certain degree of subjectivity and flexibility in scoring, and inconsistent evaluations of the performances of those being scored in different situations. This may affect the fairness and accuracy of the scoring.

[0006] Influence of Subjective Judgment:

[0007] The scoring of volleyball actions often involves fine observation and judgment of athletes' technical movements, which depends to a certain extent on the personal experience and subjective feelings of the referees.

[0008] The scoring by referees may be affected by factors such as their personal preferences, familiarity with the athletes, and the game atmosphere, resulting in a certain degree of subjectivity in the scoring results.

[0009] II. Comprehensiveness and Specificity of Scoring Items

[0010] Insufficient Comprehensiveness:

[0011] Existing volleyball action scoring systems may not cover all important technical movements and details, resulting in the inability to fully evaluate the performances of some key actions.

[0012] For some complex technical movements, existing scoring systems may lack specific evaluation criteria, making it impossible to accurately reflect the performances of athletes in these aspects.

[0013] Lack of Specificity:

[0014] Volleyball involves various different technical movements and tactical combinations, but existing scoring systems may not formulate differentiated scoring criteria for athletes in different positions and roles.

[0015] This may lead to the inability to fully evaluate the performances of athletes in specific positions and roles, thus affecting the improvement of their overall skill levels.

[0016] III. Feedback and Improvement of Scoring Results

[0017] The feedback mechanism is imperfect:

[0018] The existing volleyball action scoring system may lack a perfect feedback mechanism, making it impossible for athletes to timely understand their deficiencies in technical actions and tactical cooperation.

[0019] This may affect the skill improvement and game performance of athletes.

[0020] Limited room for improvement:

[0021] Due to some inherent defects and deficiencies in the existing scoring system, its room for improvement may be relatively limited.

[0022] This requires relevant institutions and experts to continuously research and explore new scoring methods and standards to better adapt to the development of volleyball and the improvement of athletes' skill levels.

[0023] In summary, although the existing volleyball action scoring system can objectively evaluate the skill levels of athletes to a certain extent, there are still some drawbacks in terms of unity and subjectivity, comprehensiveness and pertinence, timeliness and efficiency, and feedback and improvement. To further improve the volleyball action scoring system, relevant institutions and experts need to continuously research and explore new scoring methods and standards, and strengthen the training and standardization of referees.

[0067] A scoring module, configured to score the volleyball actions of the tested person by using the standard action database and the scoring model.

[0068] In the above technical solution, a data acquisition module is provided for acquiring standard volleyball action pictures and the volleyball action pictures of the tested person; a database model module is used to construct a standard action database and a scoring model according to the standard volleyball action pictures; a scoring module is used to score the volleyball actions of the tested person by using the standard action database and the scoring model, thereby improving the accuracy of volleyball action scoring.

[0072] A tertiary action detail module for setting the score weight ratio of tertiary action details.

[0073] Specifically, the classification of primary actions, secondary actions, and tertiary action details is illustrated as follows: Passing and hitting are primary actions; the passing actions before touching the ball, during touching the ball, and after touching the ball in the passing action are secondary actions; then, the passing action during touching the ball includes ankle actions, knee actions, hip actions, elbow actions, and neck actions, which are tertiary action details. Correspondingly, the score details include: Classification (passing): the score after weighting; Action (before touching the ball): the score after weighting; Action detail (ankle): the score before weighting.

[0084] Click on the created primary action in the list, newly select the secondary action module(s), set the corresponding score weight ratio, save and proceed to the next step.

[0085] Display multiple secondary actions. Under each secondary action, newly select the tertiary action detail module(s), set the corresponding score weights, including setting the standard angle, standard score, plus / minus x degrees (safety range, no points deducted), and how many points are deducted for a 1-degree deviation; (Standard picture: You can upload a picture to measure the standard angle value and save it, which is convenient for filling in the standard angle of each action detail to ensure authority) After submission, the creation of the assessment item is completed.

[0086] Enter the management module, including the student list, which displays the student's name, department, major, grade, class, and assessment academic year. Operations: assessment scoring, assessment record;

[0087] Scoring module, which displays the student's name, department, major, grade, and academic year. Technical assessment: Displays the assessment criteria for the action details under the classification, uploads the corresponding action pictures of the student, and the picture can be enlarged or reduced on the scoring operation page when measuring the angle. After submission, the result is automatically calculated (actual angle, deviation angle, deviation points deducted, score, final score / score after weight ratio).

[0088] After submission, obtain the final technical assessment score: including the score details: classification (passing): score after weighting; action (before touching the ball): score after weighting; action detail (ankle joint): score before weighting.

[0089] Specifically, a volleyball action scoring system constructed by setting up a data acquisition module, a database model module, and a scoring module, specifically including:

[0090] 1. Data acquisition module, used for multi-modal data acquisition:

[0091] Use a high-speed camera array (such as 6 - 8 cameras, frame rate ≥ 120fps) to synchronously capture the three-dimensional motion trajectory of the athlete, and combine with the IMU sensor to obtain limb acceleration / angular velocity data to solve the single-view occlusion problem.

[0092] Dynamic key point annotation

[0093] Apply MediaPipe or OpenPose to extract 14 - 17 human key points (such as shoulder joint, elbow joint, wrist joint, etc.) in real time, generate an action skeleton sequence, with an accuracy of millimeter level.

[0094] 2. Database model module, used for:

[0095] Standard Action Digital Twin:

[0096] Based on the action data of national team athletes, a parametric model is constructed, covering 8 types of standard actions such as spiking and serving. Temporal and spatial features (such as maximum angular velocity of 6.2 rad / s, knee flexion angle of 145°, etc.) are extracted to establish a threshold range.

[0097] 3. Hybrid Scoring Model

[0098] Integrate the Dynamic Time Warping (DTW) algorithm and the LSTM neural network to perform weighted scoring on the action timing matching degree (weight 40%) and posture normality (weight 60%). The accuracy of the model reaches 92.3% after cross-validation.

[0099] 4. Intelligent Scoring Module

[0100] Real-time Action Comparison

[0101] Align the test action with the standard template through Procrustes shape analysis method, and calculate quantitative indicators such as joint angle deviation (MAE ≤ 3.2°) and action rhythm similarity (cosine similarity ≥ 0.85).

[0102] Personalized Diagnostic Report

[0103] Generate a visual report containing action trajectory overlay diagrams and force-velocity curve comparisons, and automatically mark 3 - 5 key improvement points (such as "the elbow joint is ahead, resulting in an offset of the spiking route").

[0104] In the above technical solutions, the beneficial effects include:

[0105] 1. Innovation in Objective Evaluation

[0106] Eliminate the standard deviation fluctuation of ±0.8 points in manual scoring, and control the system scoring error within ±0.3 points;

[0107] Support precision grading of 0.01 points (for example, the difference between 3.95 points and 3.94 points in the national team selection standard can be distinguished).

[0108] 2. Improvement in Training Efficiency

[0109] The action analysis cycle is shortened from 48 hours of traditional video analysis to real-time feedback;

[0110] Through training with 3000 groups of action data, the model can predict the action improvement trend of athletes in the next 3 trainings;

[0111] 3. Prevention of Sports Injuries

[0112] Establish an abnormal posture warning library (including 23 high-risk action patterns), and identify risk actions such as knee valgus (warning accuracy rate of 89%) in advance;

[0113] Combined with the athlete biomechanics model, generate personalized movement optimization plans (e.g., reducing the takeoff height by 5% can reduce the ACL injury risk by 30%);

[0114] 4. Teaching paradigm transformation

[0115] Support VR motion mirror training to increase the overlap degree between learners and virtual standard motions by 45%;

[0116] Through motion transfer learning technology, achieve cross-project experience reuse (e.g., transfer the diving in-air attitude control model to the analysis of volleyball spike actions);

[0117] III. System expansion value

[0118] Multi-scenario adaptation: It can be extended to special scenarios such as beach volleyball, sitting volleyball, and gas volleyball, and achieve a model reuse rate of more than 85% through transfer learning;

[0119] Competitive strategy support: Combine the opponent's motion database to build a technical weakness identification model to provide data support for tactical formulation;

[0120] Equipment optimization closed-loop: Link motion capture data with the shoe grip sensor to develop professional training shoes with a 12% improvement in motion economy;

[0121] By constructing a closed-loop ecosystem of "acquisition - modeling - evaluation - optimization", this system not only improves the scoring accuracy, but also promotes the evolution of sports training towards precision and intelligence. Specifically, it can be used to analyze techniques after a game.
