[0031] Combined with appendix Figure 1-2 As shown, an integrated cooking knife skills assessment and teaching system includes a cloud service platform, an online assessment module based on the cloud service platform, and a teaching terminal. The online assessment module acquires the student's cooking knife skills data and conducts online assessments based on the cloud service platform. The teaching terminal acquires the student's assessment data, generates a teaching level based on the assessment data, and generates teaching resources based on the teaching level.

[0032] In one embodiment:

[0033] The online assessment module includes a visual data acquisition module and a motion capture module. Based on the feedback information from the visual data acquisition module and the motion capture module, data cleaning, data organization, and data assessment are performed. The cloud service platform includes data storage and teaching resource uploading. The teaching terminal includes a visual interactive teaching module and a teaching tracking module.

[0034] The visualization data acquisition module includes an image acquisition and processing camera unit set for the evaluation area; the motion capture template includes a gyroscope unit and an inertial sensor unit installed on the knife; and the teaching resource upload includes manual upload and web crawler. Manual upload includes downloading cooking teaching audio and video files through a fixed URL connected to the network and storing them on the cloud service platform. The web crawler data is stored on the cloud service platform after being reviewed by the administrator.

[0035] During online assessments, the collected data is filtered, denoised, and calibrated. An assessment model is then established based on standard data, and the assessment is conducted using the collected student data and the assessment model.

[0036] The teaching resource recording includes a multi-angle video recording unit and an audio unit; the visual interactive teaching module includes demonstrations of knife skills to students based on 3D animation and video tutorials; the audio unit allows for teaching voice communication to answer students' questions, and the teaching videos include live demonstrations of the teacher's knife skills filmed from multiple angles in virtual space, allowing students to choose from multiple perspectives when learning through the teaching videos.

[0037] The teaching tracking module includes a progress setting unit, a behavior analysis unit, and an effectiveness evaluation unit for assessing learning outcomes.

[0038] In specific implementation of the present invention,

[0039] The process includes the following steps: S1: Edit instructional videos with knife skills explanations and upload them to the cloud service platform; S2: Students download the instructional videos to learn, and after learning, they go to the testing area to take a knife skills test; S3: Set up the image acquisition and processing camera unit and install the motion capture unit with the knife; S4: Students wield the knife to process dishes according to the assessment content.

[0040] S5: The online assessment module acquires relevant test data from students, processes the data, and extracts features; S6: Based on the extracted features, an assessment model is used for assessment; S7: The teaching terminal acquires student assessment data and generates a teaching level based on the assessment data; S8: Students need to download subsequent teaching videos according to the corresponding teaching level for learning.

[0041] In one embodiment of the present invention:

[0042] It mainly consists of a cloud service platform, an online assessment module based on the cloud service platform, and a teaching terminal. The online assessment module obtains students' cooking knife skills data and conducts a comprehensive and in-depth online assessment with the help of the cloud service platform. Then, the teaching terminal generates corresponding teaching levels based on the assessment data, and generates targeted teaching resources for students according to different teaching levels, so as to achieve personalized and efficient cooking knife skills teaching.

[0043] Teachers edit instructional videos with detailed explanations of knife skills and upload them to a cloud service platform. These videos cover theoretical explanations, practical demonstrations, and precautions related to knife skills, providing students with systematic and comprehensive learning materials. Students can download the corresponding instructional videos from the cloud service platform through their learning terminals and study independently according to their own learning pace and schedule. During the learning process, students can make full use of the various functions of the visual interactive teaching module, such as viewing instructional videos from multiple angles, pausing and replaying key operation steps, and communicating and interacting with teachers or other students through the voice unit, to deepen their understanding and mastery of knife skills.

[0044] After completing the instructional videos, students need to go to a specially designed testing area to take a knife skills test. An image acquisition and processing camera unit is set up, and a motion capture unit is installed on the knife to accurately collect various data information of the students during the knife skills assessment. During the assessment, according to the requirements of the assessment content, students will swing the knife to process the specified dishes and complete the knife skills assessment task. The visualization data acquisition module and motion capture module will record the students' operation data in real time, including the shape, size, uniformity of the cut, the movement trajectory of the knife, the force and speed.

[0045] After acquiring relevant test data from trainees during the knife skills assessment, the online assessment module performs preprocessing operations such as filtering, noise reduction, and calibration on the collected data to improve data quality. Through analysis models, it extracts key features that can reflect trainees' knife skills level, including cutting stability, rhythm, accuracy, and proficiency in knife skills.

[0046] After the teaching terminal obtains the student assessment data from the online assessment module, it automatically generates the corresponding teaching level according to the preset level classification standards. The teaching level can intuitively reflect the student's current knife skills and learning progress, providing an important basis for subsequent teaching resource delivery and personalized teaching. Based on the student's corresponding teaching level, the cloud service platform will automatically push subsequent teaching videos and learning materials suitable for the student's current level, further deepening and expanding the student's knife skills knowledge and skills, and helping the student gradually improve their knife skills.
