The user can perform an operation on any drawing suggestion input displayed in the editable area, and when the user inputs a selection operation (for example, a click operation) on one drawing suggestion, a drawing pattern corresponding to the drawing suggestion can be directly displayed in the drawing area.

In the embodiment, the selection operation input by the user for any drawing suggestion is obtained, the target drawing suggestion corresponding to the selection operation is determined in at least one drawing suggestion, and then the suggestion pattern corresponding to the target drawing suggestion is displayed, so that the user can directly generate the desired drawing pattern based on a certain drawing suggestion, the idea of the user is ensured to be the same as that of the painter, the drawing operation of the painter is reduced, and the quality and the efficiency of the drawing operation are further improved.

FIG. 9 is a flowchart illustrating a method for generating a drawing suggestion according to an embodiment of the present invention; on the basis of the above embodiment, referring to fig. 9, the method in this embodiment may further include:

step S901: and acquiring the drawing state of the drawing operation.

When the drawing operation is obtained in real time, in order to improve the quality and effect of the drawing suggestion generation, the drawing state of the drawing operation can be obtained in real time, and generally, the drawing state of the drawing operation can include a drawing in-process state and a drawing completion state. Specifically, the embodiment does not limit the specific implementation manner of obtaining the drawing state, and a person skilled in the art may set the drawing state according to a specific application scenario or an application requirement, and in some examples, obtaining the drawing state of the drawing operation may include: obtaining the painting completeness corresponding to the painting pattern; and determining the drawing state of the drawing operation based on the drawing completion degree.

When the drawing operation input by the user is acquired, the drawing pattern corresponding to the drawing operation in the drawing area can be acquired, then the completion detection operation can be performed on the drawing pattern, so that the drawing completion corresponding to the drawing pattern can be acquired, specifically, all pattern elements included in the drawing pattern can be detected, then all pattern elements and all standard elements configured when the drawing pattern is completed are analyzed and compared, when the matching degree of all pattern elements and all standard elements is greater than or equal to a preset threshold value, the drawing pattern can be determined to be completed, when the matching degree of all pattern elements and all standard elements is less than the preset threshold value, the drawing pattern can be determined to be not completed, and the drawing completion corresponding to the drawing pattern can be determined based on the matching degree of the pattern elements and all standard elements.

After determining the drawing completion, the drawing completion may be analyzed to determine a drawing state corresponding to the drawing operation, for example: when the drawing completion degree is 100%, the drawing state corresponding to the drawing operation can be determined as the drawing completion state; when the drawing completion degree is 70% or 80%, the drawing state corresponding to the drawing operation can be determined to be the drawing in-process state, so that the accuracy and reliability of obtaining the drawing state of the drawing operation are effectively ensured.

In other examples, obtaining the drawing state of the drawing operation may include: obtaining the number of drawing operations corresponding to the drawing patterns; and determining the drawing state of the drawing operation based on the number of the drawing operations.

When a user performs a drawing operation, if the user has input a relatively large number of drawing operations, it is described that the user performs a relatively large drawing time and a relatively small drawing range on the drawing pattern. Therefore, in order to be able to stably acquire the drawing state of the drawing operation, the number of drawing operations corresponding to the drawing pattern may be acquired, and then the number of drawing operations may be analyzed to determine the drawing state of the drawing operation.

Specifically, based on the number of drawing operations, determining the drawing state of the drawing operation may include: when the number of the drawing operations is larger than or equal to the threshold value, determining that the drawing state of the drawing operations is a drawing completion state; and when the drawing operation number is smaller than the threshold value, determining that the drawing state of the drawing operation is a non-finished state.

Wherein different drawing patterns may correspond to different thresholds, for example: when the drawing pattern is a simple stroke, the threshold corresponding to the drawing pattern is relatively small, such as 50, 60, 100, 200, etc., and when the drawing pattern is a fine pattern, the threshold corresponding to the drawing pattern is relatively large, such as 300, 400, 500, 600, etc. Of course, the specific numerical range of the threshold is not limited in this embodiment, and a person skilled in the art can arbitrarily adjust the threshold according to a specific application scenario or an application requirement, as long as the accuracy and reliability of obtaining the drawing state of the drawing operation can be ensured, which is not described herein again.

After the number of drawing operations is obtained, the number of drawing operations can be analyzed and compared with a threshold, and when the number of drawing operations is greater than or equal to the threshold, it indicates that the number of drawing operations input by a user for a drawing pattern is large, and at this time, it can be estimated that the drawing state of the drawing operation is a drawing completion state. When the number of the drawing operations is smaller than the threshold value, the number of the drawing operations input by the user aiming at a drawing pattern is smaller, and the drawing state of the drawing operation can be estimated to be a non-finished state; therefore, the drawing state of the drawing operation is effectively ensured to be determined accurately and reliably.

Step S902: and when the drawing state is a drawing completion state, stopping generating at least one drawing suggestion corresponding to the drawing operation.

After the drawing state is acquired, the drawing suggestion can be analyzed and processed based on the drawing state, specifically, when the drawing state is a drawing completion state, the generation of at least one drawing suggestion corresponding to the drawing operation is stopped, that is, the generation of the drawing suggestion is stopped after the completion of drawing by the user is detected. When the drawing state is the drawing in-process state, at least one drawing suggestion corresponding to the drawing operation can be continuously generated.

In the embodiment, by obtaining the drawing state of the drawing operation, when the drawing state is the drawing completion state, the generation of at least one drawing suggestion corresponding to the drawing operation can be stopped, so that whether the drawing operation is completed or not can be effectively detected when the user performs the drawing operation, and if the drawing operation is completed, the drawing suggestion stops being given; if the drawing operation is not finished, the drawing suggestion can be continuously generated, so that the flexibility and the reliability of the method are effectively improved.

In a specific application, an execution main body of the display method may include an interactive drawing teaching module and a drawing board (display), where the interactive drawing teaching module is configured to perform real-time feedback on input drawing content, and the drawing board is responsible for a user to perform drawing operation and display operation of a drawing suggestion. The display method can provide drawing suggestions along the creation thought of a painter, so that the painter draws identifiable object patterns, and the drawing suggestions can be adjusted and changed along with the drawing contents input by the painter in real time; therefore, the drawing person can correctly draw recognizable patterns, and the creation, individuality and interestingness of drawing can be guaranteed.

Specifically, the display method may include the steps of:

step 1: the painter selects the object type to be painted and inputs the object type to the interactive painting teaching module.

Step 2: and the interactive drawing teaching module loads a corresponding object type model.

And 3, step 3: the painter performs drawing operation on the drawing board and inputs the drawing operation to the interactive drawing teaching module.

And 4, step 4: the interactive drawing teaching module converts drawing strokes obtained by a painter through the drawing board into vectors, and inputs the vectors into the object type model in the step 2, and the object type model can generate a plurality of drawing suggestions along the drawing thought of the painter according to the drawing strokes obtained by the drawing board so as to complement the subsequent drawing stroke scheme and enable the whole drawing pattern to be a recognizable pattern corresponding to the object type specified in the step 1.

And 5: and outputting the plurality of drawing suggestions to the drawing board, and sequentially displaying the plurality of drawing suggestions to the painter through the drawing board.

Step 6: waiting for the painter to draw next stroke.

And 7: and repeating the steps 3, 4, 5, 6 and 7 until the drawing is finished.

As shown in fig. 11, the working principle of the interactive teaching module may be: the method comprises the steps of obtaining drawing strokes input by a user through a drawing board in real time, and generating predicted drawing suggestions based on the drawing strokes, wherein S1 to Sn are assumed to be the drawing strokes input by the user through the drawing board, and Pn +1 and Pn + m are predicted strokes obtained by analyzing and processing drawing patterns through a recurrent neural network and a probability model. After the drawing strokes S1 to Sn are obtained, the drawing strokes S1 to Sn can be sequentially input into an RNN model and a probability model, the Sn strokes can be input into the probability model, the output strokes can be predicted strokes Pn +1, the predicted strokes Pn +1 are continuously input into the RNN model and the probability model, predicted strokes Pn +2 are obtained, and the predicted strokes Pn + m can be sequentially obtained. In some examples, the model may stop generating and giving drawing suggestions after detecting that the user has finished drawing the pattern, or may stop generating and giving drawing suggestions when detecting that the total number (n + m) of the predicted stroke number and the drawn stroke number is greater than 300 (a set threshold).

The drawing suggestion display method provided by the application embodiment can give the drawing suggestion of the next step according to the contents drawn by the painter in real time through the interactive drawing teaching module, has good real-time performance, and at least one generated drawing suggestion can be learned from the drawing process of tens of millions of painters in different preferences in multiple regions in the world, and has the advantages of diversity and real-time performance, so that the identifiability of the drawn pattern is effectively ensured, the creation personality and interestingness of the painter are kept, and the practicability of the method is further improved.
