[0058] The data modeling unit 25 divides the technical and tactical venues and personnel distribution recorded by multiple recording device bodies 1 into regions through an internal deep learning algorithm and a matrix data analysis method, and completes quantitative data analysis of regional rows and columns. Specifically, the data modeling unit 25 performs multi-region segmentation on the venue in the technical and tactical video to generate a matrix diagram. The data modeling unit 25 first applies a deep learning algorithm to the pre-processed images of each frame of the technical and tactical video to identify the stadium, including detecting features such as stadium lines and boundaries; then, through the matrix data analysis method, the average shoulder width of an adult of 40 cm is used as the minimum matrix unit, and the identified stadium area is segmented into multiple regions to form a matrix diagram. Please refer to Figure 5 This step involves dividing the court into multiple small areas, each of which corresponds to an element in the matrix diagram, so that the player position can be accurately identified later. After forming the matrix diagram with multiple regions, the target detection algorithm is used to identify the players in the image and locate the position of the identified players, that is, to determine their specific position in the matrix diagram. Please refer to Figure 6 This can be achieved by calculating the coordinates of the players in the image and mapping them to the corresponding positions on the matrix. By superimposing the position change analysis of the players on the matrix for each frame, combined with the actual area of ​​the sports field, the movement characteristics of the players such as movement speed and direction change are extracted to achieve the analysis of the player's trajectory and speed. Please refer to Figure 7 The athlete's movement speed can be calculated by calculating the Manhattan distance or Euclidean distance of the athlete after a certain time interval. Among them, the calculation formula of the athlete's movement speed in the embodiment of the present application is preferably:

[0066] The above is an embodiment of a technical and tactical real-time video recording and analysis system provided by the present application, and the following is an embodiment of a technical and tactical real-time video recording and analysis method provided by the present application.

[0067] Please refer to Fig.10 A technical and tactical real-time video recording and analysis method in an embodiment of the present application is applied to the above-mentioned technical and tactical real-time video recording and analysis system, and the method includes:

[0068] Step 110: Various technical and tactical diagrams, various technical and tactical film and television materials and related information are stored in the system database.

[0069] Log in to the video recording system 7, establish a system database 12, connect the system database 12 to the cloud database, and use a deep learning algorithm to update autonomously to ensure the real-time and comprehensiveness of data updates. The system database stores various types of techniques and tactics in various training and competitions, as well as relevant information, technique and tactical diagrams, and image data of techniques and tactics. The relevant information of each type of tactics includes: the name of the technique and tactic, the description of the technique and tactic, and the description of the use of the technique and tactic.

[0070] Step 120: Record the technical and tactical video of the venue in real time through the recording device body.

[0071] The video recording system is connected to multiple recording device bodies through wireless communication module wires. The multiple recording device bodies are distributed at the four corners outside the venue to ensure all-round recording and shooting of the venue and ensure the comprehensiveness of the recording.

[0072] Step 130: Play back the technical and tactical video uploaded by the recording device body through the control reference unit, and compare the technical and tactical formations and arrangements in the technical and tactical video with the data stored in the system database.

[0073] By comparing the technical and tactical formations and arrangements in the technical and tactical videos with those stored in the system database, it is convenient to provide tactical guidance, explanation and rehearsal for athletes, improve the intuitiveness and convenience of training and competition tactical design and rehearsal, so as to achieve the expected training and competition results, and help improve the review, comment and summary of the application and execution of techniques and tactics, solving the problem that traditional whiteboards cannot display tactical information in time and space, as well as the problems of tactical storage, query and display.

[0074] Step 140: The system processor divides the field in the technical and tactical video into multiple regions, generates a matrix diagram, and analyzes the athlete's motion characteristics and models the field and the athlete according to the athlete's position on the matrix diagram.

[0075] The system processor extracts images frame by frame from the recorded technical and tactical videos so that each frame can be processed and analyzed individually; image processing algorithms can be used to pre-process each frame, such as denoising, contrast enhancement, etc., to improve the accuracy of subsequent recognition.

[0076] The deep learning algorithm is applied to the pre-processed images to identify the court, including detecting the court lines, boundaries and other features. Through the matrix data analysis method, the average shoulder width of an adult of 40 cm is used as the minimum matrix unit, and the identified court area is divided into multiple regions to form a matrix diagram. This step involves dividing the court into multiple small areas, each of which corresponds to an element in the matrix diagram, so that the player position can be accurately identified later.

[0077] After forming a matrix diagram with multiple regions, the target detection algorithm is used to identify the players in the image. The identified players are located, that is, their specific positions in the matrix diagram are determined. This can be achieved by calculating the coordinates of the players in the image and mapping them to the corresponding positions on the matrix diagram.

[0078] By superimposing the position change analysis of the athletes in each frame on the matrix diagram and combining it with the actual area of ​​the sports venue, we can obtain the players' movement characteristics such as movement speed and direction change, and realize the athlete trajectory and speed analysis.

[0079] According to international competition standards or actual measurement data, the length, width, goal size and other dimensional parameters of the field are accurately recorded, and the field is divided into different functional areas, such as penalty area, goal area, midfield area, etc. Geographic Information System (GIS) technology is used to accurately divide and locate these functional areas for field modeling. Based on the previous matrix data analysis, the position of the athlete is located, combined with the athlete's physical attributes (such as height, weight, body shape), technical attributes (such as shooting, passing, ball control and other skill levels), tactical attributes (such as offensive, defensive, etc.) to model the athlete.

[0080] The present application facilitates tactical guidance, explanation and rehearsal of athletes by comparing the techniques and tactics used in real-time recorded videos with the techniques and tactics formations and arrangements in the historical database, thereby improving the intuitiveness and convenience of training and competition tactical design and rehearsal; the field is divided into a matrix diagram with multiple areas, so as to realize the analysis of athletes' movement characteristics and the modeling of the field and personnel, which is convenient for later modification and editing, and realizes subtle adjustments to techniques and tactics, saving time for modifying techniques and tactics, and presenting response tactics in a dynamic form. At the same time, simulated tactical materials for teaching and training are provided, which is convenient for improving the understanding of techniques and tactics in learning and training, and improves the technical problems existing in the prior art, such as difficulty in repeated demonstration, monotonous colors, poor attractiveness, inability of athletes to maintain concentration for a long time, difficulty in preserving tactical records, and disadvantageous for athletes to learn and remember tactics.
