To facilitate understanding of the embodiment, a drawing control method disclosed in the embodiment of the present invention will be described in detail first.
The first embodiment is as follows:
the drawing control method provided by the embodiment of the invention can be installed on a user terminal, such as a mobile terminal or other intelligent terminals, in the form of application software. In a possible embodiment, the application software is implemented based on a RenderScript framework, and a GPU (Graphics Processing Unit) and a CPU (Central Processing Unit) are fully utilized to improve the computing efficiency.
Fig. 1 shows a schematic flow chart of a drawing control method according to an embodiment of the present invention. As shown in fig. 1, the painting control method includes:
step S101, in the drawing process, acquiring the track point information of each drawing track point in the drawing track, wherein the track point information comprises position coordinates, drawing time and painting brush attributes.
Specifically, a user, such as a painter, starts a drawing function after starting corresponding software. The painter selects a corresponding painting brush to draw a painting track in the painting area. And in the drawing process, recording the track point information of each track point in the drawing track in real time. Wherein the position coordinates include an abscissa and an ordinate. The brush attributes at least comprise brush type, brush thickness, brush color and transparency.
In a possible embodiment, the user may draw the trace directly on the touch screen using a corresponding brush or with a hand.
And S102, storing the track point information of each drawing track point as drawing data, and playing the animation of the drawing track according to the drawing data.
In a possible embodiment, the drawing data may be automatically uploaded to a remote server upon completion. The drawing data may include, but is not limited to, a finally generated drawing image (composed of a drawing trace), and the drawing data may be stored in the form of a thumbnail of the drawing image for the user's convenience in selection. When the user views the drawing data, the corresponding drawing data can be downloaded by selecting the thumbnail of the corresponding drawing image, so that the drawing data can be viewed completely. Therefore, the drawing data can be distinguished easily, and the storage space of the user terminal is saved.
In a possible embodiment, the user may trigger the playing function of the drawing track by clicking a play button of a corresponding page of the application software. In order to further improve the user experience, in a possible embodiment, music information selected by the painter or other users is received, and the music information is integrated with the drawing data, so that the drawing track and the music information are played synchronously when the painter clicks the play button.
In another embodiment, each corresponding drawing trace point is time-ordered according to the drawing time in the trace point information, and is stored according to the time ordering, for example, stored into a stack or a linked list according to time. And then according to the time sequence, restoring each drawing track point in sequence according to the position coordinates, thereby replaying the drawing track in the drawing. Specifically, the reading time of each drawing track point can be shortened or increased by selecting the speed control button, so that the animation playing speed is increased or decreased.
In consideration of the fact that a painter needs to frequently change the properties of a painting brush, such as the type, thickness and color of the painting brush, in the painting process, the operation is very inconvenient. Based on the above, in the drawing process, the switching of the brush pen attribute is switched through a voice control instruction.
In a possible embodiment, referring to fig. 2, the above-mentioned brush attribute switching step includes:
step S201, when it is detected that the voice control mode is turned on, monitoring the voice information of the user in real time.
The user can click the start button of the voice control mode on the corresponding page of the software to start the voice control start mode, so that the personalized requirements of the user are met.
Step S202, after the voice information of the user is obtained, the voice information is matched with a preset voice control instruction.
And step S203, switching the current brush attribute according to the matched voice control instruction.
For example, when the user says "brush", the current type of brush is converted into a brush; when the user says "brush size 10", the brush thickness size is switched to size 10. In the execution process, the preset voice control instructions are compared with the voice information of the user one by one, so that the voice control instruction matched with the voice information is determined. And then switching the current brush attribute to the brush attribute corresponding to the matched voice control instruction.
According to the technical scheme provided by the invention, the drawing track in the drawing process can be directly played back by recording the drawing track points in the drawing track without recording the drawing process by screen video software, so that the operation is convenient and has pertinence; in addition, in the drawing process, the attributes of the drawing pen are switched by using voice control, so that the condition that a painter frequently and manually selects functions is avoided, the operation is further simplified, and the drawing process is smoother.
Considering that the user may need to delete or modify the operation within a certain time period during the drawing process, the operation is complicated by using the eraser. In a possible embodiment, the drawing control method further includes:
(a1) and receiving deletion operation information input by a user, wherein the deletion operation information comprises the time to be deleted.
Specifically, a timeline associated with the drawing data is generated in advance, and during the playing process of the drawing track, a user can select a corresponding time point by using the timeline by watching the played drawing track, so as to determine the time to be deleted. For example, the time to be deleted may be the 20 th second of playing and all time periods thereafter.
(a2) And analyzing the drawing data according to the deletion operation information, and deleting the track point information corresponding to the time to be deleted in the drawing data so as to obtain the drawing data to be perfected.
Still by taking the example in (a2), the drawing time T corresponding to the drawing trace point corresponding to the 20 th second point is determined, and the drawing time T and all drawing trace points after the drawing time T are deleted, so as to obtain the drawing data to be perfected.
(a3) And receiving the redrawing and drawing operation of a user, and obtaining redrawing and drawing data according to the redrawing and drawing operation, wherein the redrawing and drawing data comprises track point information of each redrawing track point.
(a4) And integrating the redrawing drawing data and the drawing data to be perfected to obtain perfect drawing data.
(a5) And playing the animation of the drawing track according to the perfect drawing data.
Specifically, the drawing time corresponding to the redrawing trace points and the drawing time of each drawing trace point in the drawing data to be perfected can be compared and sequenced, and then the drawing times are stacked or stored in a linked list, so that integration is completed, and perfect drawing data are obtained. And playing after monitoring the user clicks the playing sequence. Compared with an eraser, the erasing is performed by selecting the time to be erased, so that the erasing is more visual and convenient.
It is contemplated that a user may need to collaborate with other painters to complete the same painting, to facilitate communication and collaboration between painters. Based on this, in a possible embodiment, the drawing control method further includes:
(b1) receiving unfinished drawing data sent by a remote server, wherein the unfinished drawing data comprises drawing track point information and drawing task description.
Wherein the unfinished drawing data can be uploaded by other users through the user terminal. In a possible embodiment, the user terminal a may upload the unfinished drawing data to the remote server, and set a corresponding appointment password. The user terminal B may send a download request to the remote server, and download the unfinished drawing data from the remote server according to the agreed password. Wherein the drawing task description is used for prompting the user receiving the unfinished drawing data to perform the specific content of the drawing task and the drawing requirement.
In a possible embodiment, the specific implementation process is as follows: the No. 1 user can upload the unfinished drawing data to the remote server through the user terminal A, and the unfinished drawing data is pushed to other user terminals by the remote server. After the number 2 user corresponding to the user terminal B decides to receive the drawing task, feedback information can be sent to the user terminal a through the remote server. Then, the user terminal a may upload the unfinished drawing data to the remote server, and set an agreed password agreed with the user No. 2, so that the user No. 2 downloads the unfinished drawing data.
(b2) And receiving drawing operation input by a user according to the drawing task description, and obtaining supplementary drawing data according to the drawing operation, wherein the supplementary drawing data comprises track point information of supplementary track points.
(b3) And integrating the unfinished drawing data and the supplemented drawing data to obtain finished drawing data, and sending the finished drawing data to a remote server.
Still taking the user in (B1) as an example, after the user terminal B generates the supplementary drawing data, the drawing time corresponding to the supplementary trace point may be compared with the drawing time of each drawing trace point in the unfinished drawing data, and the drawing times are sorted and then stacked or stored in a linked list, so that the integration is completed, and the finished drawing data is obtained. After the drawing completion data is uploaded to the remote server, the remote server can push the drawing completion data to the exhibition area of each user terminal, or only push the drawing completion data to the user terminal a which uploads the drawing incompletion data.
Of course, the methods in the steps (b1) to (b3) are also applicable to the situation where the user needs to replace the user terminal when the drawing is not completed.
Considering that many users are beginners and the drawing level is not high, in order to help the beginners to learn and set the drawing base, in a possible embodiment, the drawing control method comprises the following steps:
(c1) and selecting an image model to be copied from the drawing model library, wherein the image model is stored with track point information of the model track points in an associated manner.
Specifically, the drawing model library may include various types of image models, such as an animal model, a cartoon character model, a landscape model, and a physical model. The image model can be drawing data which is uploaded to a remote server by a user and is audited by a drawing expert corresponding to the auditing terminal.
(c2) Receiving drawing operation input by a user according to the image model, and obtaining copy drawing data according to the drawing operation; the copying drawing data includes tracing point information of the copying tracing points.
In a possible embodiment, the copying process is copying over an original image of the image model.
(c3) And comparing the track point information of the model track point with the track point information of the copying track point to obtain the copying matching degree.
Specifically, the position coordinates in the track point information of the model track point can be compared with the position coordinates of the copying track point, and the comparison mode can be similar to the process of route matching in the prior art. In a possible embodiment, the distance deviation values between each model track point and the corresponding copying track point are compared with the deviation ranges, the deviation ranges to which the distance deviation values belong are determined, and the track matching degree is obtained. The deviation range can be divided into three ranges of no deviation, small deviation and large deviation. For example, when the deviation value of the distance between one third of the model track point and the corresponding copying track point belongs to a range with larger deviation, the track matching degree is determined to be between 30% and 40%.
In addition, whether the type, thickness, color and transparency of the painting brush of the model track point and the corresponding copying track point are consistent or not is compared, so that the matching degree of the painting brush attribute is determined; the determination of the painting brush attribute matching degree can be set according to the specific copying requirement of a user, the influence weight coefficient of each parameter in the painting attribute can be set, and then the painting brush attribute matching degree is determined according to the influence weight coefficient and whether each corresponding parameter of the model track point and the corresponding copying track point is the same or not. For example, if the user only desires the type of the brush, the user may set, but not limited to, the type of the brush to 1, set the influence weight coefficient of other parameters to 0, and determine that the matching degree of the brush attribute is 0 when the model trace point is different from the brush type of the corresponding copy trace point.
And finally, determining the final copying matching degree according to the track matching degree and the brush pen attribute matching degree. If the trajectory matching degree is multiplied by a first coefficient to obtain a first score, the brush attribute matching degree is multiplied by a second coefficient to obtain a second score, and then the first score and the second score are added to obtain the copying matching degree.
To further assist the beginner and improve the user experience, in a possible embodiment, the step (c2) of receiving a drawing operation input by the user according to the image model, and obtaining copy drawing data according to the drawing operation includes:
(d1) and when the starting of the copying prompt mode is detected, monitoring whether the user clicks a copying start button or not.

And after the drawing is started, monitoring whether the user clicks a copy start button or not in real time.
(d2) When it is monitored that the user clicks a copy start button, the user is prompted to select the painting brush attribute, and a first painting track is played in an animation mode according to track point information of the model track points.
Specifically, the image model includes a plurality of drawing trajectories. After the copying prompt mode is started, a user can be prompted to select according to the painting brush attribute in the track point information corresponding to the image model, and then a first painting track is played according to the track point information in an animation mode. The drawing tracks can be distinguished according to the start time and the end time of continuous sliding of the painting brush recorded in real time in the drawing process, and model track points are marked to determine the drawing tracks to which the painting brush belongs.
(d3) And receiving drawing operation of a user, and extracting copying track point information of each copying track point in the drawing operation in real time.
(d4) And comparing the copying track point information with the track point information corresponding to the image model in real time, and prompting the attribute of the painting brush to be switched and playing the next painting track when the copying of the first painting track is determined to be completed.
The process of comparing the copy trajectory point information with the trajectory point information of the first drawing trajectory in the image model in real time is similar to the comparison process in the trajectory matching degree in step (c3), and is not repeated here. In a possible embodiment, redrawing may be prompted when the two deviate significantly.
When it is determined that the copying of the first drawing track is completed, the drawing pen attribute corresponding to the second drawing track can be extracted for prompting, and the next drawing track is played.
(d5) And obtaining the copying drawing data until the last drawing track is determined to be copied.
And (d3) to (d4) are repeatedly executed until the copying of the last drawing track is completed. And obtaining the reddest copying drawing data. By adopting the mode, a beginner can be well guided to observe the sliding trend and direction of the painting brush and select the corresponding painting brush attribute so as to help the beginner to improve the painting level.
In order to promote the communication among the painters, the painters progress together and learn with each other. In a possible embodiment, in S102: after the trace point information of each drawing trace point is stored as drawing data, the drawing control method further includes:
(e1) and creating a type label for the drawing data, and uploading the drawing data carrying the type label to a remote server so that the remote server sends the drawing data to a corresponding auditing terminal according to the type label.
The type of the drawing data can be animal type, cartoon character type, landscape type, object type and the like. According to the type of the label, the drawing data is sent to the corresponding auditing terminal through the remote server, so that an auditor corresponding to the auditing terminal can conduct drawing auditing.
(e2) And receiving audit information returned by the audit terminal through the remote server, wherein the audit information carries a modification mark and corresponding problem description, and the modification mark comprises modification position information.
After the corresponding drawing data is loaded by the auditing terminal, the corresponding drawing track is displayed in the drawing area, the modification mark is carried out at the place needing to be modified, the modification position information of the modification mark is recorded, and the corresponding problem description is input so as to state the auditing suggestion of the terminal. And then, sending the auditing information comprising the modification marks and the corresponding problem descriptions to the corresponding user terminal through the remote server.
