[0096] The calligraphy teaching system comprises:

[0097] Database, used to store the standard fonts entered by teachers and students' writing records;

[0098] The image processing module is used to digitize the fonts written by students. The image processing module includes preprocessing and feature extraction. The preprocessing includes grayscale, binarization and noise removal. The feature extraction includes extracting the outline, skeleton and key point features of the font. The steps of the image processing module are as follows:

[0099] Grayscale: Convert a color image to a grayscale image;

[0100] Gray=0.299×R+0.587×G+0.114×B

[0101] Among them: R, G, B represent the values ​​of the red, green, and blue color channels respectively.

[0102] Then it is binarized to convert the grayscale image into a binary image. Binarization is to divide the pixel values ​​in the grayscale image into two categories: foreground (black) and background (white) through a threshold T. The specific operation method is as follows:

[0103]

[0104] Where T is the threshold, I(x,y) is the gray value of the pixel (x,y), and the commonly used threshold selection method is Otsu's method.

[0105] Noise removal: Reduce the noise in the image and retain the main writing features. The calculation method is the common median filter to remove noise;

[0106] I′(x,y)=median{I(i,j)∣(i,j)∈Neighborhood(x,y)}

[0107] Among them, Neighborhood(x,y) represents the neighborhood of point (x,y).

[0108] Feature extraction includes extracting the outline, skeleton and key point features of the font. The following is a detailed description and calculation method of each step: Using the Canny edge detection algorithm

[0109] 1. Gaussian filtering: smooth the image and reduce noise.

[0110]

[0111] Here, σ is the standard deviation of the Gaussian filter.

[0112] 2. Gradient calculation: Calculate the gradient strength and direction of each pixel in the image.

[0113]

[0114]

[0115] Among them, G x and G y are the gradients in the horizontal and vertical directions respectively;

[0116] A comparison module, used for comparing the digital font written by the student with the standard font;

[0117] An error correction module is used to generate error correction information and display the correct writing method, wherein the error correction module includes error detection, error analysis, error correction suggestion generation and correct writing method display steps;

[0118] Error detection includes feature matching and error location. Feature matching matches the student's handwriting features with the standard font features, and uses Hausdorff distance or dynamic time warping (DTW) to compare the similarity between the two. The specific algorithm is:

[0119] Hausdorff distance:

[0120]

[0121] Dynamic Time Warping (DTW):

[0122] D(i,j)=||Q i -C j || 2 +min{D(i-1,j),D(i,j-1),D(i-1,j-1)}

[0123] Among them, Q and C are the feature sequences of standard fonts and student handwriting respectively.

[0124] Error location marking: Mark the error location on the student's written image and visualize the error detection results. The specific algorithm is as follows:

[0125] Error labeling:

[0126]

[0127] Among them, ∈ is the set threshold, and Highlight(x,y) is the color or symbol used to mark the error location.

[0128] Report generation module, used to generate student written reports;

[0129] A training plan module, used to generate and adjust the targeted training plan;

[0130] The scenario analysis module is used to dynamically adjust the teaching content according to the current teaching scenario.

[0131] Student remote devices include:

[0132] Touch devices with writing capabilities;

[0133] A network interface connected to the calligraphy teaching system is used to upload the writing font and receive the error correction information.

[0134] Student remote devices also include:

[0135] Camera, used to monitor students’ writing process in real time and capture writing dynamics;

[0136] Microphone, used to record the sound information of students during the writing process to assist in judging writing behavior.

[0137] The calligraphy teaching system further comprises:

[0138] A real-time monitoring module is used to monitor the student's writing dynamics and determine whether the writing behavior has stopped;

[0139] Triggering the sending of written content: When the system determines that the writing behavior has stopped, it will trigger the sending of the current written content to the student end. This can be done through wireless transmission or local storage to ensure the timely delivery of the written content.

[0140] The stop judgment submodule judges whether the writing behavior has stopped according to the writing dynamics and sound information of the student, and triggers the sending of the writing content to the student end. The stop judgment submodule includes writing dynamic monitoring, sound information monitoring, comprehensive judgment of writing behavior and triggering the sending of writing content, including the following steps:

[0141] Writing dynamic monitoring: Use high-precision sensors (such as accelerometers, gyroscopes, pressure sensors, etc.) to monitor students' writing process in real time. These sensors can capture information such as the speed, direction, and strength of the writing pen, helping to identify subtle changes in writing behavior. The system can identify continuous writing movements and short pauses, and determine whether students have paused or interrupted their writing process;

[0142] Sound information monitoring: Equipped with a high-sensitivity microphone, it monitors the sound generated during the writing process in real time. By analyzing the frequency and intensity of the sound, the system can identify the rhythm and interruptions of writing. The sound information can help identify the beginning and end of writing, as well as whether there are pauses during the writing process. For example, when students stop to think or check reference materials during writing, the writing sound will be significantly reduced or disappear;

[0143] Comprehensive judgment of writing behavior: By comprehensively analyzing the writing dynamics and sound information, the system can accurately judge whether the student's writing behavior has stopped. Once the writing behavior is detected to have stopped, the system will trigger corresponding actions, such as saving the current writing content and preparing to send it to the student end;

[0144] The regional delivery submodule determines whether the written content belongs to the regional delivery content, and after determining that the writing behavior has stopped, delivers the written content to the corresponding student terminal. The regional delivery submodule includes the following steps: regional content identification, content classification, determination of writing behavior cessation, content delivery, feedback and interaction;

[0145] Area content recognition: The system can pre-set multiple writing areas, each of which corresponds to different writing tasks or contents. Through position sensors and image recognition technology, the system can recognize the student's writing position in real time and determine which area the current writing content belongs to;

[0146] Content classification: The system can classify the content according to the area to which the written content belongs. For example, different types of written content such as Chinese composition and science notes can belong to different areas, and the classified content can be processed according to preset rules, such as saving, transmitting or further analysis.

[0147] Determine when writing stops: After writing stops, the system will reconfirm the area to which the writing content belongs to ensure the accuracy of content classification. By comprehensively analyzing the writing dynamics and sound information, the system can avoid misjudging the cessation of writing and ensure the accuracy and timeliness of content delivery;

[0148] Content delivery: After confirming that the writing behavior has stopped and the classification is completed, the system will deliver the written content to the corresponding student terminal. The delivery process can be carried out in a variety of ways, such as wireless transmission, network synchronization, etc. The delivered content can include written text, images, videos and other forms to help students obtain and review the written content in a timely manner;

[0149] Feedback and interaction: After the content is distributed, the system can provide real-time feedback to help students correct mistakes or improve their writing in a timely manner. For example, by displaying standard answers and providing writing suggestions, students can be encouraged to learn and improve. Students can interact with the system, submit feedback or ask questions, and the system can further optimize writing monitoring and content distribution strategies based on student feedback.

[0150] When working, first, the teacher enters the standard fonts through the calligraphy teaching system. These fonts are stored in the system database, and the system allows teachers to edit and update these entered standard fonts to ensure the accuracy and real-time nature of the teaching content. Students use remote devices (such as tablets or smart pens) to write and upload the written content to the calligraphy teaching system. The remote device captures the student's writing process in real time through the touch function and uploads the written fonts to the system through the network interface. The calligraphy teaching system digitizes the student's written fonts. First, the written fonts are pre-processed through image processing technology. The steps include grayscale, binarization and noise removal. Grayscale The color image is converted into a grayscale image. The binarization converts the grayscale image into a binary image by setting a threshold. The noise removal uses the median filtering method to reduce the noise in the image. Then, through image processing and pattern recognition technology, the system compares the digital font written by the student with the standard font entered by the teacher. The comparison results include differences in position, shape, stroke order and stroke structure. If the comparison results show that the font written by the student does not overlap with the standard font, the system will generate error correction information, pointing out the specific wrong strokes and wrong positions. The system further analyzes the non-overlapping parts and determines the specific radicals. This process involves feature matching and error location. Using Hausdorff f distance or dynamic time warping (DTW) to compare the similarity between the two. Then, the system generates a detailed report based on the comparison results, which includes the radicals and components that are prone to errors in students' writing and improvement suggestions. The report can be exported as a PDF file for students to download and print. It also includes the students' writing progress and historical practice records. During the next practice, the calligraphy teaching system will conduct targeted training on the radicals and components that are prone to errors based on the generated report. The system will generate a training plan based on the improvement suggestions. The plan includes special practice content and practice frequency. The calligraphy teaching system dynamically adjusts the teaching content based on the current teaching situation. The situation analysis module adjusts the teaching content based on the students' real-time writing dynamics and practice situation. The system can adjust the teaching strategy according to the situation to ensure personalized and timely teaching. The system also includes a real-time monitoring module for monitoring students' writing dynamics, judging whether the writing behavior has stopped, and triggering the sending of the writing content to the student end. The monitoring module monitors the writing process in real time through high-precision sensors and microphones, comprehensively analyzes the writing dynamics and sound information, judges whether the writing behavior has stopped, and performs subsequent processing based on the judgment results. For example, the regional sending sub-module sends the writing content to the corresponding student end. Through the above steps, the method realizes real-time interaction between teachers and students, personalized error correction and feedback, and dynamic adjustment of teaching content according to students' writing situation, thereby effectively improving students' writing ability and learning experience.
