[0026] In order to enable those skilled in the art to more clearly understand the objectives, technical solutions and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Artificial Intelligence (AI) is the theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is a comprehensive technology in computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a similar way to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines so that machines have the functions of perception, reasoning and decision-making.

[0028] Artificial intelligence technology is a comprehensive discipline that covers a wide range of fields, including both hardware-level and software-level technologies. Basic artificial intelligence technologies generally include technologies such as sensors, dedicated artificial intelligence chips, cloud computing, distributed storage, big data processing technology, operating / interactive systems, and mechatronics. Artificial intelligence software technologies mainly include computer vision technology, speech processing technology, natural language processing technology, and machine learning / deep learning.

[0029] The present invention provides a method for generating video courseware based on artificial intelligence, which can be applied to a device supporting a Web browser or other devices that do not support a Web browser. The following is a detailed description taking the device that can be applied to the Web browser as an example.

[0030] like Figure 1 As shown, in one embodiment of the present invention, the method for generating video courseware based on artificial intelligence includes steps S10 to S40:

[0031] S10: Generate courseware pages using AIGC technology based on the content input by the user.

[0032] In the specific implementation process, the step S10 specifically includes steps S11 to S13:

[0033] S11: Use OCR technology to extract text content from various documents input by users, analyze and refine it based on user needs, and generate a courseware outline.

[0034] Specifically, Figure 2 As shown, the user inputs various documents (text, Word, PPT, PDF and other documents) into the WEB terminal, and the text content is extracted from the various documents input by the user through OCR (optical character recognition) technology, and then AI analysis and refinement are performed in combination with user needs. Finally, AIGC (artificial intelligence generation) technology is used to generate a courseware outline on the WEB terminal. Among them, the user needs are the user's text supplementary description of what theme, content and style of the courseware outline to be generated, which is used to assist AI in accurately extracting the relevant content in the document material to generate the courseware outline.

[0035] S12: Based on the user operation, the courseware outline is edited.

[0036] Specifically, in step S11, the courseware outline generated by AI may not meet the user's expectations. Therefore, the courseware outline needs to be edited based on user operations, including but not limited to regenerating, adding, deleting, modifying, and sorting the courseware outline chapters. Subsequently, AI can supplement the key points of the courseware based on the adjusted chapters to generate a courseware outline that better meets the user's needs. For example: the courseware outline generated by AI is divided into 7 chapters, and the structural redundancy can be appropriately manually deleted to 5 chapters or less; the chapter content of the courseware outline generated by AI is not satisfactory and can be regenerated.

[0037] S13: Generate a courseware page based on the edited courseware outline and the template selected by the user.

[0038] Specifically, Figure 3 As shown, AI is used to analyze the courseware outline edited in step S12, and the key points of the courseware are streamed through the AIGC technology, which is then combined with the courseware page template selected by the user to finally intelligently synthesize the courseware page on the WEB side.

[0039] S20: Extract explanation words from the text content of the courseware page, and synthesize the courseware explanation video based on the explanation words, the audio selected by the user and the digital human image.

[0040] like Figure 4 As shown, in the specific implementation process, the step S20 specifically includes steps S21 to S23:

[0041] S21: Adjust the text content of the courseware page based on user operations or using AI.

[0042] The content of the courseware page synthesized by AI is not satisfactory in terms of theme, style or other aspects. Therefore, it is necessary to adjust the content of the courseware page based on user operations or using AI. Specifically, the user can select the content of the copy to be edited on the courseware page, and click to display options. The user can use AI to polish, expand, simplify or customize the selected content to achieve automatic optimization of the copy; if the user is still not satisfied with the content of the copy regenerated by AI, the user can double-click to enter the user modification interface and actively adjust the content of the courseware page.

[0043] S22: extracting the copy content from the adjusted courseware page, and refining the copy content to obtain explanation words.

[0044] Specifically, AI technology is used to automatically identify and extract the copy content in the adjusted courseware page, and the key information in the copy content is refined to obtain explanation words.

[0045] S23: Synthesize a courseware explanation video based on the explanation words, the audio selected by the user and the digital human image.

[0046] Specifically, based on the explanation words obtained in step S22, the audio selected by the user and the digital human image, the courseware explanation video is synthesized through the AIGC technology.

[0047] S30: Based on the duration of the courseware explanation video, a timeline is added to the courseware page, and each courseware element of the courseware page is associated with the timeline to obtain a time-driven courseware page.

[0048] This step is mainly to add a timeline to the courseware page. The length of the timeline can refer to the length of the courseware video. Specifically, by inserting different time nodes in the courseware page and associating and binding each courseware element of the courseware page with the corresponding time nodes, a time-driven courseware page is obtained. When the user previews the courseware effect on the courseware page, if the preview time point coincides with the time node bound to a courseware element, the corresponding courseware element will be displayed on the courseware page.

[0049] S40: Play the courseware explanation video, and drive the time-driven courseware page based on the play time of the courseware explanation video, and record the screen and package it to generate scrom standard video courseware.

[0050] Specifically, the browser process is started through Node.Js, the courseware explanation video and courseware page are loaded through the web end, the courseware explanation video is played, and the time driving program of the courseware page is triggered to drive the courseware page based on the playing time of the courseware explanation video. At the same time, the browser screen recording program is started, and the video generated by the screen recording is packaged to generate a video courseware of the scrom standard.

[0051] The video courseware generation method based on artificial intelligence provided in the embodiment of the present invention has the following beneficial technical effects:

[0052] (1) Efficient content production: AIGC technology can quickly generate high-quality courseware content, improve the efficiency of courseware content production, and solve the problems of long production cycle and high labor cost in existing courseware production.

[0053] (2) Provide personalized courseware customization: Users can edit courseware page elements according to their own needs to achieve personalized teaching content customization.

[0054] (3) Enhanced teaching interactivity: The digital human-based courseware video is integrated with the courseware page through the timeline to provide a more vivid and interactive teaching experience.

[0055] (4) Provide standardized teaching resources: ultimately generate scrom-standard video courseware to ensure the standardization and interoperability of teaching resources.

[0056] (5) Intelligent teaching assistance: It has the function of extracting explanation words, which can extract explanation words from the courseware page to provide teaching assistance for teachers and reduce their workload.

[0057] (6) Save time and cost: Automated content generation and editing processes can save teachers’ courseware preparation time and production costs.

[0058] like Figure 5 As shown, in one embodiment of the present invention, the method for generating video courseware based on artificial intelligence includes steps S110 to S140:

[0059] S110: Generate a courseware page using AIGC technology based on the content input by the user.

[0060] For step S110 of this embodiment, Figure 1 Step S10 of the method for generating video courseware based on artificial intelligence in the illustrated embodiment is the same and will not be repeated here.

[0061] S120: extracting explanation words from the text content of the courseware page, and synthesizing the courseware explanation video based on the explanation words, the audio selected by the user and the digital human image.

[0062] For step S120 of this embodiment, Figure 1 Step S20 of the method for generating video courseware based on artificial intelligence in the illustrated embodiment is the same and will not be repeated here.

[0063] S130: Based on the duration of the courseware explanation video, a timeline is added to the courseware page, and each courseware element of the courseware page is associated with the timeline. At the same time, test questions are generated based on the courseware page and inserted into the courseware page to obtain a time-driven courseware page.

[0064] This step is mainly to add a timeline to the courseware page. The length of the timeline can refer to the length of the courseware video. Specifically, by inserting different time nodes in the courseware page and associating and binding each courseware element of the courseware page with the corresponding time node, a time-driven courseware page is obtained.

[0065] like Figure 6 As shown, step S130 of this embodiment is Figure 1 The difference of step S30 of the video courseware generation method based on artificial intelligence in the illustrated embodiment is that: while adding the timeline, a test question is also generated based on the courseware page and inserted into the courseware page, and the test question is associated and bound with the corresponding time node. Specifically, in the process of the user editing the courseware page, the front-end page will regularly extract the page content snapshot and provide it to AI for parsing. When the user drags to a specific time point in the courseware timeline and selects to insert a test question, AI will quickly generate a test question based on the page content snapshot and the courseware theme and bind the corresponding time node. At the same time, the user can configure the generated test question (addition, deletion, passing requirements for answering questions, time limit for answering questions, etc.); when the user previews the courseware effect on the courseware page, when the preview time point coincides with the time node bound to the test question, a test question box will pop up to simulate the real courseware answering effect.

[0066] S140: Play the courseware explanation video, and drive the time-driven courseware page based on the play time of the courseware explanation video, and start screen recording at the same time. The video combination test questions generated by the screen recording are packaged to generate a scrom standard video courseware.

[0067] Specifically, Figure 7 As shown, the browser process is started through Node.Js, the courseware explanation video and the courseware page are loaded through the web end, the courseware explanation video is played, and the time driving program of the courseware page is triggered to drive the courseware page based on the playing time of the courseware explanation video. At the same time, the browser screen recording program is started, and the video combination test questions generated by the screen recording are packaged to generate scrom standard video courseware.

[0068] The video courseware generation method based on artificial intelligence provided in the embodiment of the present invention has the following beneficial technical effects:

[0069] (1) Efficient content production: AIGC technology can quickly generate high-quality courseware content, improve the efficiency of courseware content production, and solve the problems of long production cycle and high labor cost in existing courseware production.

[0070] (2) Provide personalized courseware customization: Users can edit courseware page elements according to their own needs to achieve personalized teaching content customization.

[0077] S210: Generate a courseware page using AIGC technology based on the content input by the user.

[0078] For step S210 of this embodiment, Figure 1 Step S10 of the method for generating video courseware based on artificial intelligence in the illustrated embodiment is the same and will not be repeated here.

[0079] S220: Extract explanation words from the text content of the courseware page, synthesize the courseware explanation video and generate subtitles based on the explanation words, the audio selected by the user and the digital human image.

[0080] Step S220 of this embodiment is Figure 1 The difference of step S220 of the method for generating video courseware based on artificial intelligence in the illustrated embodiment is that, while synthesizing the courseware explanation video, subtitles corresponding to the courseware explanation video are generated.

[0081] S230: Based on the duration of the courseware explanation video, a timeline and subtitles are added to the courseware page, and each courseware element of the courseware page is associated with the timeline. At the same time, test questions are generated based on the courseware page and inserted into the courseware page to obtain a time-driven courseware page.

[0082] Step S230 of this embodiment is Figure 5 The difference of step S130 of the method for generating video courseware based on artificial intelligence in the illustrated embodiment is that it also includes adding subtitles to the courseware page. Specifically, the subtitles corresponding to the courseware explanation video are first loaded, and then the subtitles are added to the courseware page, and finally, each subtitle is associated and bound with the corresponding time node, thereby completing the addition of subtitles.

[0083] S240: Play the courseware explanation video, and drive the time-driven courseware page based on the play time of the courseware explanation video, and start screen recording at the same time.
