[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] In the description of the present invention, the terms "comprises", "has" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may also include other steps or units that are not explicitly listed but are inherent to these processes, methods, products or apparatuses, or steps or units added based on further optimization schemes conceived by the present invention.

[0040] Please refer to Figure 1 , which shows a flow chart of a sprint intelligent evaluation method based on face recognition provided by an embodiment of the present application, which may include the following steps:

[0041] S1, install intelligent collection devices at the starting point and the end point of the runway, and capture facial images through the intelligent collection devices.

[0042] Among them, the intelligent collection equipment includes at least a high-resolution camera and an edge computing device. The high-resolution camera is used to capture faces, and the edge computing device is used to perform preliminary face detection and preprocessing.

[0043] In this step, smart acquisition devices are installed at the start and end of the runway in the school playground. These devices include high-resolution cameras and built-in edge computing modules. High-resolution cameras are used to capture facial images in real time to ensure image clarity and quality, which can meet the needs of face recognition. In this application, the runway can be a 50-meter runway or a 100-meter runway.

[0044] Intelligent collection equipment is connected via a gigabit wired network to ensure the stability and real-time performance of data transmission.

[0045] The edge computing module is responsible for the preliminary processing of the captured facial images, including face detection, image preprocessing (such as grayscale, normalization, cropping and enhancement), and face angle judgment, reducing the amount of data transmission and improving the system response speed.

[0046] When students enter the running area, the intelligent acquisition device automatically starts the capture process, captures the students' facial images, and performs preliminary processing to prepare for subsequent facial recognition.

[0047] In an optional embodiment of the present application, an effective capture time is set. When the intelligent acquisition device is running, it will obtain the current time in real time and compare it with the set effective capture time. When entering the running area within the effective capture time, the intelligent acquisition device will start the capture process;

[0048] Set a minimum number of captured photos. During the capture process, the intelligent collection device will count the photos captured by each student. When processing the captured data, it will check whether the number of captured photos of each student reaches the set minimum threshold. Only when the number of captured photos reaches or exceeds the set minimum number, the student's running data will be counted and recorded in the database.

[0049] S2, each facial image captured at the starting point is used for facial recognition using a deep learning model, and is compared one by one with a pre-stored student face database to determine whether the student corresponding to each facial image is the target to be tested. If the comparison is successful, the identity information of the successfully matched student is associated with the running record.

[0050] In this step, the intelligent acquisition device transmits the preliminarily processed facial image to the back-end system through the network.

[0051] The face recognition engine in the back-end system uses a deep learning model to perform high-precision recognition of captured facial images.

[0052] This deep learning model is based on large-scale data training and can detect 150 key points, accurately locate facial features (such as eyebrows, eyes, nose, lips, cheeks, etc.) and contours, and support recognition of single and multiple faces.

[0053] The system makes angle judgments on facial images and combines them with the spatial posture angle reference of the face to enhance the accuracy and robustness of recognition.

[0054] During the recognition process, the system will compare the captured facial image with the pre-stored student face database one by one to determine whether the student is a student of this school (i.e., the target to be tested).

[0055] If the match is successful, the system will associate the student's identity information with the running record, providing a basis for subsequent data statistics and analysis.

[0056] S3, taking face capture of students passing the finish line to identify the target to be measured, and collecting the running data of the target to be measured.

[0057] Among them, running data includes duration and pace data.

[0058] In this step, while the target to be measured (confirmed student) is running, the intelligent data acquisition device captures the face of the student passing the finish line.

[0059] The system uses facial comparison to confirm whether the captured student is the target to be tested, ensuring the accuracy of the data. The running time is calculated by recording the difference between the student's start time and the end time; the pace is calculated by dividing the running mileage by the running time. The system transmits the collected running data to the back-end system in real time for storage and further processing.

[0060] In an optional embodiment of the present application, human body recognition is also included:

[0061] When the target is running, the intelligent data acquisition device not only captures the face, but also starts the body recognition function at the same time. Body recognition technology can detect a single or multiple people in the picture, track the people, and feedback the relative position of the people in the picture.

[0062] The human body recognition algorithm can detect the student's body outline in real time and track it. Even when the face is partially blocked (such as wearing a hat, mask, etc.) or the face cannot be captured clearly due to angle problems, the human body recognition technology can still confirm the student's identity and location through the body outline and movement trajectory.

[0063] Human body recognition technology can provide information about the relative position of the human body in the image, helping the system to more accurately determine whether students have passed through monitoring points and their specific positions during running.

[0064] During the face capture process, human body recognition technology can assist in confirming whether the captured face belongs to a student who is running, avoiding data errors caused by mistakenly capturing other non-running people.

[0065] In a scenario where multiple people are running, human body recognition technology can distinguish different students and ensure that each student's running data is accurately collected. Even if there is overlap between students or the queues are tight, human body recognition technology can still accurately distinguish them through body contours and movement trajectories.

[0066] The location information provided by human body recognition technology can more accurately calculate students' running mileage and pace.

[0067] During running, human body recognition technology can provide real-time feedback on students' exercise status, helping the system to adjust data collection strategies in a timely manner to ensure the accuracy and completeness of the data.

[0068] S4, performs real-time processing and statistical analysis on the collected running data to generate intelligent evaluation results of the target to be tested.

[0069] In this step, the back-end system processes the received running data in real time, including data cleaning, verification and integration, to ensure the accuracy and completeness of the data.

[0070] Generate a personalized sports analysis report based on the student's running time and pace data, combined with the student's age, gender and historical sports data; the sports analysis report includes the student's starting reaction time, acceleration phase performance, sprint phase speed, overall sports trend analysis and targeted training suggestions.

[0071] The intelligent evaluation results are displayed to students and administrators in real time through a user-friendly interface (such as a large sunlight screen), and can also be sent to relevant personnel in the form of electronic reports, providing a scientific basis for the school's physical education and management. The user-friendly interface supports a variety of interactive methods, and displays running student information and the school's daily / weekly leaderboard; the running student information includes the student's head portrait and today's running mileage, and the school's daily / weekly leaderboard includes the student's name, class, total running mileage, and total duration information for each day / week.

[0072] In an optional embodiment of the present application, during the data transmission and storage process, SSL / TLS encryption technology is used to encrypt the student's identity information and running data.

[0075] The recognition module is used to perform face recognition on each face image captured at the starting point using a deep learning model, and compare it one by one with the pre-stored student face database to determine whether the student corresponding to each face image is the target to be tested. If the comparison is successful, the identity information of the successfully matched student is associated with the running record;
