To facilitate understanding of the present embodiment, first, a video generating and video displaying method disclosed in the embodiments of the present disclosure is described in detail, where an execution subject of the video generating and video displaying method provided in the embodiments of the present disclosure is generally a computer device with certain computing capability, and the computer device includes, for example: a terminal device, which may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle mounted device, a wearable device, or a server or other processing device.

Referring to fig. 1, a flowchart of a video generation method provided in an embodiment of the present disclosure is shown, where the method includes steps 101 to 103, where:

step 101, obtaining topic information of a topic to be solved.

102, generating at least one problem solving step of the to-be-solved problem and parameter analysis information corresponding to each problem solving step of the to-be-solved problem based on the problem information of the to-be-solved problem and a pre-trained problem solving model.

And 103, generating an explanation video corresponding to the to-be-solved subject based on the parameter analysis information corresponding to each problem solving step of the to-be-solved subject.

The following is a detailed description of the above steps 101 to 103.

For step 101,

In a possible implementation manner, if the execution main body for obtaining the topic information of the topic to be solved is the server, when obtaining the topic information of the topic to be solved, a generation instruction carrying the topic information of the topic to be solved sent by the client may be received, and the topic information of the topic to be solved is obtained based on the generation instruction.

In practical application, the manner of obtaining the topic information of the topic to be solved may be any one of the following manners:

the method comprises the steps of firstly, obtaining the question information of the to-be-solved question input by a user at a preset input position.

In a possible implementation manner, the client may be preset with an input location area, and the user may input the title information of the topic to be solved in the input location area by means of typing or copying and pasting.

If the execution main body for acquiring the title information input by the user at the preset input position is the client, the client can directly acquire the title information of the to-be-solved title after the user inputs the title information at the input position region; if the execution main body for acquiring the topic information of the to-be-solved question input by the user at the preset input position is the server, the client sends the topic information of the to-be-solved question to the server after the user inputs the topic information of the to-be-solved question at the input position region, so that the server acquires the topic information of the to-be-solved question.

And secondly, acquiring media contents such as images, videos and audios containing the topic information of the to-be-solved topic, and extracting information in the media contents to obtain the topic information of the to-be-solved topic.

If the execution main body for acquiring the image containing the topic information of the topic to be solved is a client, acquiring the image containing the topic information of the topic to be solved through a camera carried by terminal equipment, and acquiring the topic information of the topic to be solved contained in the image through Optical Character Recognition (OCR) and other Recognition technologies;

if the execution main body for acquiring the image containing the topic information of the to-be-solved question is a server, acquiring the image containing the topic information of the to-be-solved question through a camera carried by a client-side acquisition terminal device, determining the topic information of the to-be-solved question contained in the image through recognition technologies such as OCR (optical character recognition), and finally sending the topic information of the to-be-solved question to the server; alternatively, the first and second electrodes may be,

the server can directly acquire an image which is sent by the client and contains the topic information of the to-be-solved question, the image can be acquired by calling a camera of the electronic equipment deployed by the client, and then the topic information of the to-be-solved question is obtained through recognition technologies such as OCR (optical character recognition).

When the media content containing the topic information of the to-be-solved question is a video, the video can be subjected to frame extraction, so that the topic information containing the to-be-solved question is determined, and then the topic information of the to-be-solved question is obtained through recognition technologies such as OCR (optical character recognition); when the media content containing the topic information of the to-be-solved question is audio, the audio can be converted into text content containing the topic information of the to-be-solved question through a voice recognition technology, and therefore the topic information of the to-be-solved question is obtained.

With respect to step 102,

Wherein the parameter analysis information includes a plurality of information among:

The calculation type corresponding to the calculation formula may be a type used to describe a preset calculation template adopted by the calculation formula, for example, the calculation type may include "factor, product", "addend, and", "find the least common multiple", "find the greatest common factor", "average, number, total", and the like.

Illustratively, the topic information shown below is input to the neural network model:

fruit stores have 120 kg of pears, apple mass is 3/4 for pears, orange mass is 2/3 for the sum of pear and apple mass, how many kg are oranges?

After the neural network model processes the topic information, output contents shown in table 1 can be generated:

TABLE 1

In a possible implementation manner, when at least one problem solving step of the problem to be solved and the parameter analysis information corresponding to each problem solving step of the problem to be solved are generated based on the problem information of the problem to be solved and the pre-trained problem solving model, the problem information of the problem to be solved can be input into the pre-trained problem solving model, and at least one problem solving step and the parameter analysis information corresponding to each problem solving step are output.

The neural network model may be a Natural Language Processing (NLP) model, and the neural network model may be obtained by training based on a sample topic carrying analysis labeling information.

For step 103,

In a possible implementation manner, when the explanation video corresponding to the subject to be solved is generated based on the parameter analysis information corresponding to each problem solving step of the subject to be solved, the explanation video corresponding to the subject to be solved can also be generated based on the subject information of the subject to be solved and the parameter analysis information corresponding to each problem solving step of the subject to be solved.

In a possible implementation manner, when generating an explanation video corresponding to a subject to be solved based on parameter analysis information corresponding to each problem solving step of the subject to be solved, reference may be made to the method shown in fig. 2, which includes the following steps:

step 201, determining an animation display template matched with the to-be-solved problem.

In a possible implementation manner, when the animation display template matched with the to-be-solved subject is determined, the display attribute information of each display module in the animation display template may be determined based on at least one problem solving step of the to-be-solved subject, wherein the display attribute information may include a display area and/or a display number.

For example, an animation display template may be as shown in fig. 3, a first position region of the animation display template may be used to display title information of a title to be solved, and when an animation display template matching the title to be solved is determined, a display area of the first position region may be determined; the second position area of the animation display template can be used for displaying the logic derivation of the solution problem corresponding to the solution problem step, and when the animation display template matched with the solution problem is determined, the display number of the display modules in the second position area can be determined; and the third position area of the animation display template is used for displaying detailed solutions of the problem solving step, and when the animation display template matched with the to-be-solved problem is determined, the display area of the third position area can be determined.

Step 202, adding the parameter analysis information to the animation display template based on the solving sequence corresponding to the solving step of the to-be-solved question; and determining audio information corresponding to the parameter parsing information.

In a possible implementation manner, when determining the audio information corresponding to the parameter analysis information, the audio information corresponding to the topic information may be generated based on the topic information of the topic to be solved; and then generating audio information corresponding to the problem solving step based on the formalized audio information matched with the logic sequence and the parameter analysis information of different problem solving steps and the parameter analysis information of the problem solving step.

Here, the audio information corresponding to the problem solving step may include first audio information derived by the problem solving logic, and second audio information detailed by the problem solving step, i.e., audio information corresponding to the second location area and audio information corresponding to the third location area in fig. 3.

In one possible embodiment, the formalized audio information for generating the first audio information corresponding to different topics to be solved may be the same, and may for example include "request XXX, require XXX" corresponding audio information; the second audio information includes audio information of analysis content corresponding to different problem solving steps, and formalized audio information used for generating the audio information of the analysis content corresponding to different problem solving steps may be different.

Specifically, the formal audio information of the analysis content corresponding to different problem solving steps in the second audio information may be related to the calculation type in the parameter analysis information of the problem solving steps, for example, when the calculation type is "addend, and", the formal audio information corresponding to the calculation type may be the audio information corresponding to "add with __________ and __________"; when the calculation type is "factor, product", the formalized audio information corresponding to the calculation type may be the audio information corresponding to "multiplication by __________ and __________".

And 203, fusing the audio information and the animation display template added with the parameter analysis information to obtain an explanation video corresponding to the to-be-solved subject.

In a possible implementation manner, when the audio information is merged with the animation display template, the display duration of the display module corresponding to each piece of audio information in the animation display template may be determined based on the playing duration of the audio information, and then the audio information is merged with the animation display template based on the display duration of each display module to obtain the explanation video corresponding to the to-be-solved subject.

Specifically, in the explanation video, each display module can be sequentially displayed, when any display module is displayed, the audio information corresponding to the display module can be simultaneously played, and after the audio information corresponding to the display module is played, the next display module can be displayed.

In practical application, the explanation video corresponding to the to-be-solved subject may include two types of videos, one is an explanation video that is only displayed, and the other is an explanation video that interacts with the user, the explanation video that is only displayed may be generated based on the animation display template, when the subject information of the to-be-solved subject is acquired, a type selection instruction input by the user may be simultaneously acquired, if the explanation video that is only displayed is selected to be generated in the type selection instruction of the user, the explanation video is generated based on the above method, and if the explanation video that is interactive is selected to be generated in the selection instruction of the user, the following method may be referred to.

In a possible implementation manner, when an explanation video corresponding to a subject to be solved is generated based on parameter analysis information corresponding to each subject solving step of the subject to be solved, the explanation video may include two parts, one part is to determine at least one section of an interactive sub-video based on the parameter analysis information corresponding to each subject solving step of the subject to be solved, a subject solving sequence corresponding to each subject solving step, and a preset interactive animation display template; and the other part is that each explanation sub-video corresponding to the to-be-solved subject is generated based on the parameter analysis information corresponding to each problem solving step of the to-be-solved subject, the problem solving sequence corresponding to each problem solving step and a preset explanation template, and the interactive sub-video and the explanation sub-video form the explanation video.

The interactive sub-video is a sub-video that can be subsequently displayed only by the interaction between the user and the user side, for example, a display page of the interactive sub-video may be as shown in fig. 4, each derivation step displayed in the second location area requires the user to select, and the user may select the derivation step by triggering an option of the third location area, where the option includes the calculation significance of the calculation formula in the parameter analysis information corresponding to the problem solving step and the significance of the calculation parameter.

In practical application, if the user selects correctly, namely after the user triggers the computational significance of the computational formula in the analysis parameter information corresponding to the current problem solving step, prompt information can be added on the display page, the user is prompted to select correctly, and information corresponding to the option selected by the user is added in the display module in the second position area; if the user selects the wrong option, a prompt voice for prompting the user to select the wrong option can be played, the correct option is displayed, and the correct option is added into the display module of the second position area.

In one possible implementation, the presentation sequence of each interactive sub-video may be preset, and the explanation sub-video may be presented after the interactive sub-video is presented.

In a possible implementation manner, at least one text problem solving step corresponding to the to-be-solved item may be generated according to the problem solving sequence corresponding to each problem solving step and the analysis parameter information corresponding to each problem solving step, then each text problem solving step is sequentially displayed in the third location area (the audio information corresponding to the text problem solving step may be synchronously played while the text problem solving step is displayed), and then after any text problem solving step is completely displayed, a mark indicating that the calculation of the step is completed is added to the display module corresponding to the second location area.

For example, as shown in fig. 5, after displaying the speeds of the two vehicles and the corresponding calculation steps, a check mark may be added at the position of "speed sum of two vehicles" to indicate that the calculation of the step is completed.

In another possible implementation manner, the parsing content corresponding to the to-be-solved item may be generated based on the parameter parsing information corresponding to each problem solving step and a preset parsing template, where the parsing template may include a formal language matched with the parameter parsing information and the logic sequence of different problem solving steps.

In a specific implementation, the parsing content corresponding to the to-be-solved subject may include a first parsing content for representing a problem solving logic and a second parsing content for representing a detailed problem solving step. The parsing template is different in the formal language used for generating the first parsed content and the second parsed content.

In a possible implementation manner, the formal languages used for generating the first parsing content in the parsing templates corresponding to different to-be-solved questions may be the same; the second analysis content comprises analysis content corresponding to different problem solving steps, and the formal languages used for generating the analysis content corresponding to the different problem solving steps in the analysis template can be different.

Illustratively, still taking the question of the fruit shop in step 102 as an example, the problem solving template can be as shown in table 2:

TABLE 2

In specific implementation, the content to be supplemented in the table above can be perfected based on the analysis parameter information corresponding to each problem solving step and the problem solving sequence corresponding to each problem solving step.

Specifically, (1) correspondingly filling the calculation significance of the calculation formula in the third step; (2) filling the calculation significance of the calculation formula in the second step correspondingly; (3) filling the calculation significance of the calculation formula of the first step correspondingly; (4) processing the meaning of the calculation formula corresponding to the first step; (5) (6) correspondingly filling the meaning of each calculation parameter in the calculation formula of the first step; (7) (8) correspondingly filling the calculation result of the calculation formula of the first step and the meaning of the corresponding parameter; (9) (10) correspondingly filling the meaning of each calculation parameter in the calculation formula of the second step; (11) (12) correspondingly filling the calculation result of the calculation formula of the second step and the meaning of the corresponding parameter; (13) the meaning of the calculation result and the corresponding parameter of the calculation formula (question answer) corresponding to the third step is filled.

After the parsing parameter information corresponding to the solving step is sequentially added to the preset parsing template based on the solving sequence corresponding to the solving step, the text parsing content shown in table 3 can be obtained:

TABLE 3

Based on the same concept, the embodiment of the present disclosure further provides a video display method, as shown in fig. 6, which is a schematic flow chart of the video display method provided by the embodiment of the present disclosure, and the method includes the following steps:

601, responding to a preset trigger operation aiming at a to-be-solved question, and initiating an explanation request; wherein, the explanation request carries the subject information of the subject to be solved.

Step 602, receiving an explanation video corresponding to the subject to be solved.

603, displaying the explanation video through a user side; the explaining video comprises at least one solving step of the to-be-solved question and parameter analysis information corresponding to each solving step of the to-be-solved question.

The explanation video may include an interactive sub-video and an explanation sub-video, and in one possible implementation, the explanation sub-video or the interactive sub-video corresponding to a trigger operation of any interactive sub-video in the explanation video may be displayed in response to the trigger operation.

Specifically, a plurality of triggerable buttons may be displayed in the interactive sub-video, different trigger buttons correspond to different explanation sub-videos or interactive sub-videos, and after any button is triggered, the explanation sub-video or the interactive sub-video corresponding to the button may be displayed.

It will be understood by those skilled in the art that in the method of the present invention, the order of writing the steps does not imply a strict order of execution and any limitations on the implementation, and the specific order of execution of the steps should be determined by their function and possible inherent logic.
