Step S104, receiving real-time action information and real-time voice information corresponding to the two-dimensional character model input by the user.

For the embodiment of the application, the electronic equipment receives the real-time action information and the real-time voice information corresponding to the two-dimensional character model input by the user, wherein the real-time action information can be a signal sent to the electronic equipment by a worker through triggering a keyboard or other equipment, the real-time voice information can be the voice information sent by the worker, and the electronic equipment collects the voice information. For example:

The electronic equipment receives a signal that a user walks rightwards through a character sent by a trigger keyboard, and the electronic equipment collects voice information of 'getting back and forth when playing snow'.

Step S105, generating a two-dimensional animation based on the scenario information, the real-time action information, the real-time voice information, the prompt action information and the prompt line information.

In one possible implementation manner of the embodiment of the present application, the step S103 generates the prompting action information and the prompting speech information of the two-dimensional character model based on the scenario information and the background image information, which specifically includes a step S1031 (not shown in the figure), a step S1032 (not shown in the figure), a step S1033 (not shown in the figure), and a step S1034 (not shown in the figure), where,

in step S1031, feature extraction is performed on the background image information to determine the size of the object in the background image information.

For the embodiment of the application, the electronic equipment performs feature extraction on the background image information to determine the size of the object in the background image information, performs color filtration on the background image information through the gray value of the background image information, and extracts the boundary contours of all the objects in the background image information. After the boundary contour is extracted, the electronic device establishes a rectangular coordinate system by taking any point on the boundary contour as an origin, extracts the highest point and the lowest point in the vertical direction of the boundary contour by the electronic device, further obtains the height of the object, extracts the left boundary point and the right boundary point in the horizontal direction of the boundary contour by the electronic device, further obtains the width of the object, and further obtains the size of the object by determining the height and the width of the object. Taking step S101 as an example:

The electronic equipment extracts the boundary outline of the house where the sheep lives, and then the height of the house of the sheep is 8 cm and the width of the house of the sheep is 6 cm;

the electronic equipment extracts the boundary contour of the stone in front of the house, and then the stone is 1 cm in height and 1 cm in width;

the electronic equipment extracts the boundary outline of the snowman of the small sheep pile, and then the height of the snowman is 3 cm and the width of the snowman is 2.5 cm.

Step S1032, determining the character size of the two-dimensional character model in the background image information based on the scenario information.

For the embodiment of the present application, the electronic device determines the character size of the two-dimensional character model in the background image information based on scenario information, where scenario information includes introduction of a character and introduction of other objects, taking step S1031 as an example:

the figure introduction of the small sheep in the scenario information introduces that the height of the small sheep is 1 meter, the height of the house where the small sheep lives is 1.5 meters, the ratio of the size of the house where the small sheep lives to the size of the small sheep is 1.5:1 calculated by the electronic equipment, and then the electronic equipment determines that the size of the small sheep in the background image information is as follows:

8.1.5=5.3 cm.

Step S1033, generating presentation action information based on the scenario information, the size of the object, and the person size.

For the embodiment of the application, the electronic equipment generates the prompt action information based on the scenario information, the size of the object and the figure size, because actions required to be sent by the figures of the objects with different sizes in the scenario information are different, and in order to reduce confusion of staff on the actions, the electronic equipment outputs related prompt action information.

Step S1034, generating presentation speech information based on the scenario information.

For the embodiment of the application, the electronic device generates the prompting speech information based on the scenario information, wherein the scenario information comprises speech of each character, for example:

the scenario information comprises the typhoons: in the future, we go to play with the snow bar-! The electronic device can output on the screen "snowy today, we go to play with the snow bar-! The electronic equipment can also send the prompting speech information to the terminal equipment of the user, so that the staff can input real-time speech information based on the prompting speech information, and the situation that the staff forgets the speech is reduced.

In one possible implementation manner of the embodiment of the present application, the step S1033 generates the prompting action information based on the scenario information, the size of the object and the figure size, and specifically includes a step S1033a (not shown in the figure), a step S1033b (not shown in the figure), and a step S1033c (not shown in the figure), where,

step S1033a, determining whether the two-dimensional character model needs to generate an action based on the scenario information.

For the embodiment of the application, the electronic device determines whether the two-dimensional character model needs to generate actions based on scenario information, for example:

The scenario information is provided with words such as jumping, the electronic equipment captures the part of speech and the semanteme of the line based on the natural language technology, and the electronic equipment determines that the two-dimensional character model needs to generate actions. The electronic device may also determine whether the two-dimensional model persona needs to generate an action in other ways, which is not limited herein.

Step S1033b, if necessary, determines presentation action information based on scenario information, object size, and character size.

The prompting action information comprises action content and action sequence.

For the embodiment of the application, if the electronic equipment judges that the character of the two-dimensional model needs to generate the action, the electronic equipment determines action prompt information based on the scenario information, the size of the object and the character size. Taking step S1032 and step S1033a as an example:

the electronic equipment determines that the goats need to walk out of a room and go to a snowman by a stone to squat down the snowman based on the plot information, determines that the first action of the goats is forward straight movement, the second action is left turning, the third action is left straight movement, the fourth action is jumping, the fifth action is left straight movement, the sixth action is squat down, and the seventh action is stroking based on the plot information. The user is assumed to input real-time action information by triggering a keyboard, the action corresponding to the S+D key is forward straight, the action corresponding to the L key is left-turning, the action corresponding to the L+D key is leftward straight, the action corresponding to the J key is jumping, the action corresponding to the D key is squatting, and the action corresponding to the F key is stroking.

The prompting action information may be text information that "s+d goes straight forward, L turns left, l+d goes straight left, J jumps, l+d goes straight left, D crouches down, and F touches" is output on the display screen of the electronic device in the form of text, or text information or voice information may be sent to the terminal device of the staff, which is not limited herein.

The electronic device can set a first preset height ratio and judge the times of jumping of the goats when the goats pass through the stone based on the jumping distance of the goats. If the width of the stone is smaller than the 1-time jumping distance of the sheep and larger than the first preset height ratio, determining that the sheep can pass through after jumping for 1 time; if the width of the stone is smaller than the 2 jumping distances of the goats and smaller than the first preset height ratio, determining that the goats can pass through the goats after jumping for 2 times.

The electronic equipment judges that the height of a stone in front of a house in background image information is 1 cm wide and 1 cm, the height of a small sheep is 5.3 cm, the 1-time jumping distance of the small sheep in the background image information is 1.5 cm, the first preset height ratio is 1:8, the height ratio of the stone to the small sheep is 1:5.3 and is larger than the first preset height ratio, the width of the stone is smaller than the 1-time jumping distance of the small sheep, and the small sheep can jump over the stone through one-time jumping.

In another implementation manner, the electronic device may set a second preset height ratio, where the second preset ratio is smaller than the first preset ratio, and if the electronic device is smaller than the second preset ratio, the electronic device determines that the sheep needs to bypass and cannot pass through the jump.

In step S1033c, if not required, the presentation action information is determined to be stationary.

For the embodiment of the application, if the electronic equipment judges that the character of the two-dimensional model does not need to generate action, the electronic equipment determines that the prompt action information is kept still. Taking step S1033b as an example:

after the electronic equipment determines that the snowman of the sheep piles on the basis of the scenario information does not need to generate other actions after squatting and stroking, the prompting action information output by the electronic equipment is kept still and is used for prompting the staff not to input other real-time action information. The prompting action information may be text information which is output on a display screen of the electronic device in a text form, or may be text information or voice information which is sent to a terminal device of a worker, and is not limited herein.

One possible implementation manner of the embodiment of the present application, in step S105, a two-dimensional animation is generated based on scenario information, real-time action information, real-time voice information, prompt action information, and prompt line information, which specifically includes step S1051 (not shown in the figure), step S1052 (not shown in the figure), step S1053 (not shown in the figure), step S1054 (not shown in the figure), step S1055 (not shown in the figure), and step S1056 (not shown in the figure), where,

Step S1051, a two-dimensional animation is generated based on the real-time motion information and the real-time voice information.

For the embodiment of the application, the electronic equipment receives the real-time action information and the real-time voice information, and generates the two-dimensional animation based on the real-time action information and the real-time voice information, thereby completing the production of the two-dimensional animation.

Step S1052, determine whether the prompt action information is the same as the real-time action information.

For the embodiment of the application, the worker can input the real-time action information for controlling the left turn by triggering the L key, and the electronic device judges whether the real-time action information is the same as the prompt action information or not based on the real-time action information, taking step S1033b as an example:

assuming that the electronic equipment receives an L key triggered by a worker, and the action corresponding to the L key is left turn, the electronic equipment detects that the real-time action information is the same as the L key in the prompt action information. Assuming that the electronic equipment receives a D key triggered by a worker, and the action corresponding to the D key is squatting, the electronic equipment judges that the real-time action information is different from the L key in the prompt action information.

In step S1053, if they are not the same, a prompt question is output.

Wherein the prompt question is used to ask whether real-time action information and real-time voice information need to be re-input.

For the embodiment of the application, if the electronic device judges that the real-time action information and the prompt action information are different, the electronic device outputs a prompt question, and the prompt question is used for inquiring whether the real-time action information and the real-time voice information need to be input again, and the prompt information can be text information of whether the real-time action information and the real-time voice information need to be input again or not sent to the terminal device of the staff, can be voice information of whether the real-time action information and the prompt action information need to be input again or not sent by the control loudspeaker device, and can also be prompt information in other forms.

Step S1054, receive the selection result corresponding to the prompt question, and determine the selection result.

Wherein the selection result includes yes and no.

For the embodiment of the application, the electronic equipment receives the selection result corresponding to the prompt problem sent by the user, determines the selection result, and the user can select yes or no by triggering the content on the touch screen, and also can select yes or no by triggering the key on the keyboard.

Step S1055, if the two-dimensional animation is the same or not, judging whether the generation of the two-dimensional animation is completed or not based on the scenario information.

For the embodiment of the application, if the electronic equipment judges that the real-time action information is the same as the prompt action information, or if the electronic equipment receives the selection result of the prompt problem, the electronic equipment does not need to input the real-time action information and the real-time voice information again, the electronic equipment judges whether the generation of the two-dimensional animation is completed or not based on the scenario information, the scenario information is possibly divided into a plurality of chapters, and only the first chapter and other chapters are generated currently. Taking step S1033b as an example:

After the electronic equipment completes the scenario that the goats need to come out of a room and go to the snowman by a stone to squat down and pile the snowman, the scenario information can also exist that the goats run to the bunny to find the bunny to play and teach the snowman piled by the bunny, and the electronic equipment judges that the two-dimensional animation is not completed.

Step S1056, if the generation is not completed or yes, the steps of receiving the real-time action information and the real-time voice information corresponding to the two-dimensional character model input by the user, generating the two-dimensional animation based on the real-time action information and the real-time voice information, judging whether the prompt action information is the same as the real-time action information, if not, outputting the prompt problem, receiving the selection result corresponding to the prompt problem, and if not, judging whether the generation of the two-dimensional animation is completed based on the scenario information until the generation is completed.

For the embodiment of the present application, as shown in fig. 4, if the electronic device determines that the two-dimensional animation is not generated, or if the electronic device receives the selection result of the prompting problem, it indicates that the electronic device needs to continuously receive the real-time motion information and the real-time voice information corresponding to the two-dimensional character model input by the user, and generates the two-dimensional animation based on the real-time motion information and the real-time voice information again, and determines whether the prompting motion information is the same as the real-time motion information, if not, the prompting problem is output, the selection result corresponding to the prompting problem is received, and if the prompting problem is the same or not, it determines whether the two-dimensional animation is generated based on scenario information;

And as long as the electronic equipment judges that the two-dimensional animation is not generated, the electronic equipment continuously receives the real-time action information and the real-time voice information corresponding to the two-dimensional character model input by the user, and performs a series of operations for generating the animation until the two-dimensional animation is generated. So that the generated two-dimensional animation effect is better, the number of modification times of later editing is reduced, and the efficiency of manufacturing the two-dimensional animation is improved.

In one possible implementation manner of the embodiment of the present application, the step S1051 generates a two-dimensional animation based on the real-time motion information and the real-time voice information, which specifically includes a step S10511 (not shown in the figure), a step S10512 (not shown in the figure), and a step S10513 (not shown in the figure), where,

in step S10511, the two-dimensional character model is controlled to generate a corresponding motion based on the real-time motion information.

For the embodiment of the application, the electronic equipment controls the two-dimensional character model to generate corresponding actions based on the real-time action information, such as basic actions of limbs such as walking, running, striding, jumping and the like or facial expressions of some joysticks and fun.

In one possible implementation manner of the embodiment of the present application, step S10511 includes step S10511a (not shown in the figure), step S10511b (not shown in the figure), and step S10511c (not shown in the figure) when the two-dimensional character model is controlled to generate the corresponding motion based on the real-time motion information, wherein,

in step S10511a, the motion coordinates of the two-dimensional character model corresponding to the real-time motion information are matched in the storage means.

For the embodiment of the application, the electronic device matches the motion coordinates of the two-dimensional character model corresponding to the real-time motion information in the storage unit, and the electronic device establishes a space rectangular coordinate system with the center of the character as the origin, and represents the coordinates of each limb of the character, for example:

the coordinates of the right foot (-0.77,1.29,0.15) and the coordinates of the left foot (-0.77,1.29,0.15), and when the electronic device receives the real-time motion information as a jump, the electronic device matches the coordinates of the left foot and the right foot corresponding to the jump in the storage unit, and assuming that the coordinates of the right foot (-0.77,2.5,1.15) and the coordinates of the left foot (-0.77,2.5,1.15) after the jump of the person matched in the storage unit by the electronic device.

In step S10511b, the duration of the motion of the two-dimensional character model at the motion coordinates is determined.

For the embodiment of the present application, the electronic device determines the action duration of the two-dimensional character model at the action coordinates, taking step S10511a as an example:

the electronic equipment knows based on the scenario information that the character only performs simple jumping and has no other complex actions, the electronic equipment determines that the conventional jumping action is 0.5 seconds, and the electronic equipment determines that the two-dimensional character model resumes the coordinates before jumping after the action duration of the jumping action coordinates is 0.5 seconds and 0.5 seconds.

Step S10511c, outputting an action corresponding to the two-dimensional character model based on the action coordinates and the action duration.

In accordance with an embodiment of the present application, taking step S10511b as an example, the electronic device outputs an action that the two-dimensional character model is from rest to jump, and the character is then rest after the jump lasts for 0.5 seconds.

In one possible implementation manner of the embodiment of the present application, the step S10512 controls the two-dimensional character model to generate the corresponding voice based on the real-time voice information, and the step S10513 combines the voice and the action, which specifically includes a step S10512a (not shown in the figure), a step S10512b (not shown in the figure), a step S10513a (not shown in the figure), a step S10513b (not shown in the figure), and a step S10513c (not shown in the figure), where,

In step S10512a, tone color information corresponding to the two-dimensional character model is matched in the storage unit.

For the embodiment of the application, the electronic equipment matches tone information corresponding to the two-dimensional character model in the storage unit, the tone information of each character in the storage unit is named by the name of the character or other special characters, and then the electronic equipment matches the name to obtain the tone information corresponding to the character. For example:

the electronic equipment names tone color information by the name of the character, and the electronic equipment matches tone color information corresponding to the character of the sheep through the 'sheep'.

In step S10512b, dubbing information corresponding to the two-dimensional character model is generated based on the real-time voice information and the tone information.

For the embodiment of the present application, the electronic device generates dubbing information corresponding to the two-dimensional character model based on the real-time voice information and the tone information, taking step S10512a as an example:

and when the electronic equipment receives the real-time voice information as 'you are' and the electronic equipment is matched with the tone information of the sheep, the electronic equipment outputs the 'you are' of the tone information of the sheep as the dubbing to the sheep.

In step S10513a, the real-time voice information is analyzed and the analysis result is determined.

For the embodiment of the application, the electronic device receives the real-time voice, and performs phoneme analysis on the real-time voice, for example:

the electronic equipment receives real-time voice information as follows: if you are thank, the electronic device performs phoneme analysis on the sentence, and the analysis result is that 10 phonemes exist in the sentence: taixienile.

Step S10513b matches the mouth shape corresponding to the two-dimensional character model in the storage unit based on the analysis result.

For the embodiment of the present application, the electronic device matches the mouth shape corresponding to the two-dimensional character in the storage unit based on the analysis result, taking step S10513a as an example:

and each phoneme has corresponding mouth shape information, the electronic equipment matches the mouth shapes corresponding to 10 phonemes of the taixiensis in the storage unit, and then the electronic equipment generates complete mouth shape information of the sentence of 'Taixie you' based on the sequence of the taixiexifile in the initial real-time voice information.

Step S10513c, the mouth shape and the motion are combined, and the dubbing information is output.

For the embodiment of the application, the electronic device combines the mouth shape information and the action and simultaneously outputs dubbing information, for example:

the electronic equipment combines the complete mouth shape information of the sentence which is "thank you" with the jumping action of the character, and simultaneously controls the character to send the dubbing information of the sentence which is "thank you" for the corresponding tone color information, so as to generate a complete animation combining voice, mouth shape and action.
