It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

Referring to fig. 1, a flowchart illustrating a video generation method provided in an embodiment of the present disclosure is shown, where the method includes steps 101 to 104, where:

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

And 102, determining at least one problem solving step corresponding to the problem to be solved and parameter analysis information corresponding to each problem solving step of the problem to be solved based on the problem information of the problem to be solved.

The following is a detailed description of the above steps.

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,

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

Illustratively, the parameter analysis information comprises a calculation formula, a calculation meaning of the calculation formula, and a meaning of a calculation parameter in the calculation formula; in another example, the parameter parsing information may further include unit information, and/or a calculation type corresponding to the calculation formula.

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 solving problem 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 problem solving model processes the problem information, the output content shown in table 1 can be generated:

TABLE 1

For step 103,

In one possible embodiment, when the interactive parameter information corresponding to the at least one problem solving step is determined based on the parameter analysis information corresponding to the at least one problem solving step, for any problem solving step, any N of the computational significance of the computational formula of the other problem solving steps except the problem solving step and the significance of the computational parameter in the computational formula, and the computational significance of the computational formula of the problem solving step may be used as the interactive parameter information corresponding to the problem solving step, where N is a preset positive integer.

For example, continuing the above example, for the second-step problem solving step, the interactive parameter information includes the total mass of the apples and the pears, and may further include any two of the calculation meaning of the calculation formula in the first-step problem solving step and the second-step problem solving step and the meaning of the calculation parameter in the calculation formula, for example, the mass of the oranges, the ratio of the mass of the apples to the mass of the pears, and the like.

Here, the meaning of the calculation parameter in the calculation formula may be the meaning of the calculation parameter in the calculation formula of a step other than the problem solving step, or the meaning of the calculation parameter in the calculation formula of all the problem solving steps.

The interactive parameter information corresponding to the at least one problem solving step is determined based on the parameter analysis information corresponding to the at least one problem solving step, and may be the interactive parameter information corresponding to a target problem solving step in the at least one problem solving step based on the parameter analysis information corresponding to the at least one problem solving step, or the interactive parameter information corresponding to the problem solving step is determined for each problem solving step. The interactive parameter information corresponding to the same problem solving step does not include the same parameter information.

With respect to step 104,

In a possible implementation manner, when generating an interactive sub-video corresponding to a topic to be solved based on the interactive parameter information corresponding to at least one topic solving step, reference may be made to the method shown in fig. 2, which includes the following steps:

step 201, for each problem solving step, determining an interactive video corresponding to the problem solving step based on the interactive parameter information corresponding to the problem solving step.

Specifically, for each problem solving step, the interactive parameter information corresponding to the problem solving step may be added to the interactive animation template corresponding to the problem solving step, so as to obtain the interactive animation corresponding to the problem solving step; determining first audio information corresponding to the interactive animation; and then fusing the interactive animation corresponding to the problem solving step with the first audio information corresponding to the interactive animation to obtain the interactive video corresponding to the problem solving step.

In practical application, the problem solving step may correspond to the same interactive animation template, and the information added to the interactive animation template may further include the problem information of the problem to be solved and the problem information for the interactive parameter information. The interactive animation template can comprise a plurality of display modules, and different display modules are used for displaying different contents.

For example, a video frame of an interactive animation to which the interactive parameter information, the topic information of the topic to be solved, and the question information for the interactive parameter information are added may be as shown in fig. 3.

The first audio information corresponding to the interactive animation can be audio information corresponding to content displayed in the interactive animation; in a possible implementation manner, when the interactive animation is merged with the corresponding first audio information, the presentation duration of the presentation module corresponding to each segment of the first audio information in the interactive animation template may be determined based on the playing duration of the first audio information, and then the first audio information and the interactive animation are merged based on the presentation duration of each presentation module to obtain the interactive video corresponding to the problem solving step.

Continuing the above example, the question information of the to-be-solved question corresponds to first audio information 1, the question information for the interactive parameter information corresponds to first audio information 2, and different interactive parameter information respectively corresponds to first audio information 3, first audio information 4, and first audio information 5, so that when the first audio information is fused with the interactive animation, the playing duration of the first audio information 1 can be determined first, and then the question information of the to-be-solved question is displayed within the corresponding playing duration; and then determining the playing time length of the first audio information 2, then displaying the problem information aiming at the interactive parameter information in the corresponding playing time length, wherein the displaying mode of the interactive parameter information is similar to that described above, and after all the contents added to the interactive animation template are displayed, the playing of the first audio information corresponding to the interactive animation is finished.

Step 202, arranging the interactive videos corresponding to the problem solving steps according to the problem solving sequence corresponding to the problem solving steps to obtain the interactive sub-videos corresponding to the to-be-solved problems.

Here, it should be noted that, the interactive sub-videos corresponding to the to-be-solved items are obtained by arranging according to the problem solving sequence corresponding to the problem solving steps, and the interactive sub-videos corresponding to the to-be-solved items are played according to the problem solving sequence instead of splicing the interactive videos corresponding to the problem solving steps.

In a possible implementation manner, each interactive video corresponds to a plurality of interactive result videos, and the interactive result videos correspond to interactive parameter information in each interactive video in a one-to-one manner; and the interaction result video is used for displaying after the corresponding interaction parameter information is triggered.

Illustratively, if the problem solving step includes a problem solving step 1 and a problem solving step 2, the interactive animation corresponding to the problem solving step 1 includes three pieces of interactive parameter information, the interactive animation corresponding to the problem solving step 2 includes four pieces of interactive parameter information, each piece of interactive parameter information may correspond to an interactive result video, the interactive sub-video includes the interactive video corresponding to the step 1 and the interactive video corresponding to the step 2, and the display sequence should be: and displaying the interactive video corresponding to the step 1, responding to the triggering operation of the user on the interactive parameter information A in the displayed interactive video, displaying the interactive result video corresponding to the interactive parameter information A, then displaying the interactive video corresponding to the step 2, responding to the triggering operation of the user on the interactive parameter information B in the displayed interactive video, and displaying the interactive result video corresponding to the interactive parameter information B.

In a possible implementation manner, if the interaction parameter information triggered by the user is correct, the interaction animation corresponding to the next problem solving step of the current problem solving step can be directly and sequentially displayed, and if the interaction parameter information triggered by the user is wrong, the interaction animation interface of the current problem solving step can be returned, and the user is prompted to reselect.

In a possible implementation manner, when generating an explanation video corresponding to an item to be solved based on parameter parsing information corresponding to at least one problem solving step, a method as shown in fig. 4 may be used, which includes the following steps:

step 401, determining an explanation animation template matched with the to-be-solved subject.

In a possible implementation manner, when the explanation animation template matched with the to-be-solved subject is determined, the display attribute information of each explanation module in the explanation animation display template may be determined based on the parameter parsing information corresponding to the to-be-solved subject, where the display attribute information includes a display area and/or a display number.

For example, the explanation animation template may be as shown in fig. 5, a first position region of the explanation animation template may be used to display the subject information of the subject to be solved, and when an animation display template matching the subject to be solved is determined, the display area of the first position region may be determined; the second position area of the explanation animation template can be used for displaying the solution logic derivation corresponding to the solution step (namely, the calculation meaning corresponding to each solution step), and when the explanation animation template matched with the to-be-solved question is determined, the display number of the display modules in the second position area can be determined; and the third position area of the illustrated explanation animation template is used for displaying detailed explanation of the problem solving step, and when the explanation animation template matched with the to-be-solved problem is determined, the display area of the third position area can be determined.

Step 402, based on the problem solving sequence corresponding to the at least one problem solving step, adding the parameter analysis information corresponding to the at least one problem solving step to the explanation animation template, and determining second audio information corresponding to the explanation animation template after the parameter analysis information is added.

In one possible embodiment, in determining the second audio information corresponding to the explanation animation template after adding the parameter resolution information, the second audio information may be generated based on the formalized audio information matching the logical order of the different problem solving steps and the parameter resolution information, and the parameter resolution information of the problem solving step.

Here, the second audio information corresponding to the explanation animation template after the parameter resolution information is added may include audio information derived by the problem solving logic, and audio information detailed in the problem solving step, that is, the audio information corresponding to the second location area and the audio information corresponding to the third location area in fig. 5.

In a possible implementation manner, the formal audio information used for generating the second audio information corresponding to different topics to be solved may be the same, for example, the audio information of the analysis content corresponding to different topic solving steps may be included, and the formal audio information used for generating the audio information of the analysis content corresponding to different topic 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 403, fusing the second audio information with the explanation animation template added with the parameter analysis information to obtain the explanation video.

The method for fusing the second audio information and the explanation animation template is the same as the method for fusing the interactive animation and the first audio information, and will not be described herein again.

Based on the same concept, an explanation video display method is further provided in the embodiments of the present disclosure, and referring to fig. 6, a flowchart of the explanation video display method provided in the embodiments of the present disclosure includes the following steps:

step 601, obtaining topic information of a topic to be solved, and determining an explanation video corresponding to the topic to be solved.

The explanation video is based on the topic information of the to-be-solved topic is generated, the explanation video comprises an interactive sub-video and an explanation sub-video, the interactive sub-video comprises interactive videos corresponding to at least one topic solving step respectively, each interactive video corresponds to a plurality of interactive result videos, and the explanation video further comprises the interactive sub-video and a display sequence corresponding to the explanation sub-video.

And 602, displaying the explanation videos according to the display sequence.

Step 603, responding to the trigger operation aiming at the currently displayed interactive sub-video, and displaying the interactive result video corresponding to the trigger content based on the trigger content corresponding to the trigger operation.

In a possible implementation manner, the trigger content is interaction parameter information in an interaction sub-video currently displayed, and the interaction result video corresponding to the trigger content is an interaction result video corresponding to the interaction parameter information.

In a possible implementation manner, after the interaction result video corresponding to the trigger content is displayed, the explanation video after the currently displayed interaction sub-video may be displayed according to the display order.

The explanation video after the currently displayed interactive sub-video may be an interactive sub-video in a next problem solving step of the currently displayed interactive sub-video.

Or, in another possible implementation manner, if the trigger content corresponding to the trigger operation is not the target content of the current interactive sub-video, that is, the interactive parameter information triggered by the user is not the correct answer corresponding to the question information in the currently displayed interactive sub-video, a final display result page for displaying the current interactive sub-video may be returned to prompt the user to reselect. And under the condition that the trigger content corresponding to the trigger operation is the target content of the current interactive sub-video, displaying the interactive result video of the interactive parameter information corresponding to the trigger operation, and then sequentially displaying the interactive sub-videos of the next problem solving step.
