[0052] Embodiment 1:
[0053] This embodiment provides an intelligent training and assessment method based on multi-source data analysis. Figure 1 , Figure 2 As shown, the following steps are included:
[0054] Step 1: Collect historical training and test information and real-time training and test information to obtain multi-source training and test data.
[0055] Specifically, according to different protocols, multi-source hardware devices such as training equipment, assessment equipment, cameras, physical measurement instruments, watches, scanners, etc. are connected to collect data, and training and examination information from other training and examination systems is connected to obtain historical training and examination data and real-time training and examination data.
[0056] Step 2: Use a data analysis algorithm to process the multi-source training and testing data to obtain multi-source effective training and testing data, thereby realizing the fusion of multi-source training and testing data.
[0057] The specific steps of the data parsing algorithm include:
[0058] Step 1: Analyze the text data of the training and examination documents, and support data extraction of tables, stamps, column paragraphs, pictures, formulas, etc.

[0060] A1. Use neural network algorithms to detect text content and identify complex training texts (such as training tables, seals, column paragraphs, pictures, etc.) and simple training texts (such as common training text content, formulas, etc.).
[0061] A2. For complex training texts, they are processed by constructing a generative network and a discriminative network. The discriminative network is used to distinguish the content and format of the training texts; the generative network is used to generate false data similar to the content of the training texts.
[0062] The objective function is:
[0063]
[0064] In the formula, u represents the number of types of complex training and test texts; i represents the weight; D is the mapping function for distinguishing the content of the training test text and the format of the training test; G is the mapping function for generating the content of the training test text; x i The data consists of the real training and test text content and training and test format; data The distribution of data consisting of real training and test text content and training and test format; i represents the noise of random training text content; p z Represents the noise distribution of random training text content.
[0065] A3. Continuously train and optimize the constructed generative network and discriminative network, and finally obtain the optimal u-type text content generated by the generative network, from which the training and test format content has been removed.

Use the CRNN algorithm to perform text recognition on the text content obtained in A3 and the simple training text, draw lines according to the coordinate sequence of the characters, and use the neural network to classify the drawn lines into common reading sequences, and map the recognized text content to obtain text content that matches the reading sequence.
[0067] Step 2: Use the YOLO algorithm as the detection network to detect blurry frames in the video information of multi-source training data, and introduce the attention mechanism to capture important blurry frame information; use the RNN network as the deblurring network to process blurry frames. Among them, the detection network and the deblurring network are integrated into a pipeline to process a blurry video into a clear video, reducing the impact of the environment such as lighting and darkness.

CAT stands for cascade operation; Conv stands for convolution operation; F t After upsampling through the deconvolution layer, images of t frames of the training and testing video are generated to replace the original blurred images and obtain clear training and testing videos.

By constructing a causal relationship network between risk warning influencing factors, the ability level can be assessed according to the training and test indicators, and alarms can be issued for physical abnormalities.
[0073] The evaluation algorithm includes the following steps:
[0074] Step 1: Obtain student training and test videos in real time, and use computer vision technology to analyze and evaluate the head and facial emotions, lower limb gait, and whole-body movement in the training and test videos to obtain video analysis results; video analysis results include: student emotional state, physical injury status, and athletic ability.
[0075] Specifically, the steps include:

Use Transformer neural network to extract 3D features of head facial expressions, lower limb gait movements, and whole body movement movements.
[0077] B2. Use 3D human posture estimation algorithm to identify movement changes, and capture the dependency between features based on graph convolutional neural network, identify the standard state of movement (low, medium, high), emotional state (normal and abnormal), and injury state (mild, medium, high) during exercise, use 3D reconstruction technology to show the position of real movement and the amplitude that standard movement should reach, use Gan to optimize the details of movement position generation, and then compare the gap between the trainees' real movement and standard movement.
[0078] Among them, the loss functions of 3D reconstruction technology include:

[0090] B4. Obtain real-time training and test videos, repeat steps B1 and B2 to obtain data field information such as the difference between the real action and the standard action, emotional state (normal and abnormal), injury status (mild, moderate, and severe), etc., and input them into the trained lightGBM algorithm regression in B3 to give a real-time score and assess the ability level.
[0091] Step 2: Construct portraits of the training and examination texts obtained above (including: training and examination results, training and examination plans, training and examination personnel information, training and examination physical fitness information and skill subject information, etc.) according to individual and group training indicators (including: psychological indicators, morphological indicators, physiological indicators, biochemical indicators, mechanical indicators, sports injury type indicators) and five-dimensional radar charts (including: speed, endurance, strength, flexibility, and agility) to obtain health status values; analyze the relationship between physical fitness and skills, the relationship between quality and skills, and the relationship between quality and physical fitness, analyze weights, analyze the strengths and weaknesses of individuals and groups in various training indicators and their changing trends over time, and combine the analysis results of the training and examination videos in step 1 to predict risks and give physical abnormality warnings.

[0093] C1. Analyze historical and real-time physical fitness and skill training and test data and personal information data for individuals and groups, and analyze physical fitness test subjects T n Subjects for performance and skills assessment J m Performance and quality indicators x Use linear regression algorithm to calculate the weight W corresponding to the quality index in the physical fitness assessment subject score xn And the corresponding weight W of the quality index in the skill assessment subject score xm , thus obtaining the historical and real-time five-dimensional radar chart. The five-dimensional radar chart value can be calculated according to the following formula:
[0094]
[0095] In the formula, M1 and M2 represent the number of physical fitness assessment subjects and the number of skill assessment subjects respectively.
[0096] At the same time, according to historical and real-time psychological indicators, morphological indicators, physiological indicators, biochemical indicators, mechanical indicators, sports injury type indicator data S y , using the neural network algorithm to supervise the training weights W aa and W bb , get the health status value: S = W aa S x +W bb S y .

[0100] Both
[0101] In the formula, M3 represents the number of quality indicators; S nx Indicates the quality value of the physical fitness assessment subject corresponding to the quality index; S mx Indicates the quality value of the skill assessment subject corresponding to the quality indicator.
[0102] C3. By monitoring the real-time training and test data of individual and group students, we analyze the strengths and weaknesses of individual and group indicators and their changing trends over time. Combined with the analysis results of the training and test videos in step 1, we use the support vector machine algorithm to predict the risk threshold. By comparing the relationship between the predicted value and the risk threshold, we give a physical risk warning.
[0103] Step 3: Use big model technology to intelligently generate relationships, attributes and entities for students' historical training and examination information, such as training and examination subjects, scores, videos, personnel, indicators, plans, etc., build knowledge graphs, establish causal networks, enhance reasoning capabilities, and analyze potential connections through correlation mining. Analyze each person's health status, ability level, shortcomings and strengths, and then optimize risk thresholds. The big model can give risk warnings and guidance suggestions, and continuously adjust the results based on the questions and answers between users and the big model.
[0104] Step 4: Intelligently group different groups of people and provide personalized training plans for different groups. The training plans can be divided into adaptation period, development period, sprint period and assessment period. Correct exercise posture, training plan and dietary suggestions can be given. Knowledge services such as text, video and pictures as well as targeted guidance and exercise rehabilitation prescriptions can be provided to injured persons. Real-time monitoring of physical condition can be carried out and warnings can be given.
[0105] Specifically, the steps include:
[0106] D1. Based on the five-dimensional radar charts, psychological indicators, morphological indicators, physiological indicators, biochemical indicators, mechanical indicators, and sports injury indicators of individuals and groups obtained above, the random forest algorithm is used to group the trainees according to individuals and groups for training. The grouping categories include: sports injury group SG, psychological training group XG, basic training group CG, skill training group JG, and comprehensive training group ZH. Each group is divided into primary pr, intermediate mi, and advanced hi. Each level can be divided into adaptation period sy, development period fz, sprint period cc, and assessment period kh. The Y level P period under the X group can be recorded as X YP ,X∈(SG,XG,CG,JG,ZH),Y∈(pr,mi,hi),P∈(sy,fz,cc,kh).

The Actor network gives a corresponding training plan based on the status of real-time training and testing analysis data, and the Critic network gives an effect evaluation based on the status of real-time training and testing analysis data.
[0111] The training and testing status is a collection of five-dimensional radar chart values and health values, and the action is that the intelligent agent gives a corresponding training plan based on the status of real-time training and testing analysis data.
[0112] Total reward: r = w1r1 + w2r2 + w3r3. The closer to the training target value, the larger the value.
[0113] Where r1=-(V A -V s ) 2 ,
[0114]
[0115] r3=-γ t ,
[0116] Where V A represents the actual training evaluation value, V s represents the training target value, γ t is the optimal time coefficient. If the time exceeds a certain range, a negative reward value is given. The farther away from the ideal time range, the smaller the value.
