All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in other sequences than those illustrated or otherwise described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense to distinguish one object from another, and not necessarily to limit the number of objects, e.g., the first object may be one or more. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The following describes in detail the drawing processing method provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a schematic flow chart of a drawing processing method according to an embodiment of the present disclosure, where the drawing processing method is applied to an electronic device with a touch screen, such as a mobile phone, a tablet computer, and a notebook computer.
The drawing processing method may include:
step 101: a first line and a second line drawn in a drawing area are acquired.
The first line and the second line in this step are two separate lines adjacent to each other in drawing time, that is, no other line is drawn in a time period between the drawing times of the two lines. For example, when the drawing start time is counted as 0 second, the drawing time of the first line is 12 seconds to 14 seconds, the drawing time of the second line is 15 seconds to 16 seconds, and no line is drawn between 14 seconds to 15 seconds, the drawing time is: 12 to 14 seconds and plot time: 15-16 seconds, which are adjacent drawing time, and the first line and the second line are two separated lines adjacent to the drawing time.
The drawing area described in this step may include, but is not limited to: for inputting text information into a handwriting input area in an electronic device (e.g., a handwriting input area in an input method application), a drawing area (e.g., a canvas area in a drawing board application), etc.
Step 102: and under the condition that the first line and the second line are separated from each other, displaying a third line formed by connecting the first line and the second line in the drawing area.
When a user draws a graph, the separation of some lines is intended by the user, for example, when a Chinese character 'three' graph is drawn in a handwriting input area of an input method application, in order to enable the input method application to more accurately recognize the graph, the user draws three superimposed and separated lines in the handwriting input area. However, sometimes the separation between lines may be caused by drawing errors, for example, a user writes characters in a handwriting input area in an input method application in a running vehicle, but due to vehicle jolt, a touch body (such as a finger, a touch pen, etc.) is unstable, and an original stroke is disconnected to form two strokes, in this case, the separation between lines is caused by the drawing errors, which may affect the accuracy of the input method application for the user to recognize the written characters, resulting in character recognition errors, and for this reason, the user may need to manually repair the lines to avoid the occurrence of character recognition errors.
In view of the foregoing problems, in the embodiment of the present application, when it is determined that two lines are separated from the same line (that is, separated due to a drawing error), the electronic device may automatically perform line repairing, connect the two lines, and display the connected lines in the drawing area, so that firstly, the drawing error may be compensated, and the integrity of the graph may be improved; secondly, the operation of manually repairing the line by a user can be saved; and thirdly, the lines can be repaired under the condition that the user does not sense the disconnection of the lines, the problem that the lines are not used during drawing is reduced, and the use experience of the user is improved. The technical scheme provided by the embodiment of the application can improve the accuracy of text and graphic recognition especially under the condition of inputting text information through a handwriting input area.
Wherein the drawing error may include: at least one of a user-induced drawing error and an electronic device-induced drawing error. The following explains a drawing error caused by an electronic device as an example.
As an alternative embodiment, at step 102: in a case where it is determined that the first line and the second line are separated from each other, before a third line formed by connecting the first line and the second line is displayed in the drawing area, the drawing processing method may further include:
determining a target area according to the foldable area and the drawing area of the screen; obtaining drawing tracks of a first line and a second line; determining whether the first line and the second line meet preset conditions or not according to the target area and the drawing track; under the condition that the first line and the second line meet preset conditions, acquiring a first graph and a second graph; and determining that the first line and the second line are separated from the same line based on the first graph and the second graph.
The target area may be an area determined according to an overlapping area of the screen foldable area and the drawing area, and the target area includes the overlapping area, that is, the overlapping area may be the same area as the target area or a local area in the target area.
Wherein the first graph is a graph included in the drawing area when the first line is separated from the second line; the second pattern is a pattern included in the drawing region when the first line and the second line are connected.
Along with the pursuit of a user on a large screen, the folding screen is produced, and the user can fold or unfold the folding screen so as to meet the use requirements of the user on screens with different sizes. Some of the foldable screens are foldable in a fixed position, such as the foldable screen shown in fig. 2, and the middle area 201 (i.e., the area outlined by the dashed line) of the foldable screen is a foldable area. For such a folding screen, since the foldable area is a connection area of two screens and needs to support a flexible and foldable function, when the screen is completely unfolded, there may be a problem that the foldable area is not in the same horizontal plane as other areas of the screen, resulting in unevenness of the entire screen. Therefore, when a graph is drawn on the touch screen, the touch body cannot contact the screen area when the middle section of one line is drawn due to the fact that the screen is not flat, so that the line is broken, and the problem of two independent lines is solved. For a scene of inputting text information in a handwriting mode, due to stroke breakage, a recognition result of the handwriting input text information is likely to be influenced, and a situation of recognition error occurs.
For the folding screen of the type mentioned above, the position of the foldable area is fixed, so that when the drawing area draws a figure, the area (i.e. the target area) where the drawing line is easy to break can be determined according to the foldable area of the screen and the drawing area. As shown in fig. 3, the folding screen includes a first screen 301 and a second screen 302, and the first screen 301 and the second screen 302 are connected by a foldable area 303. Fig. 3 shows 304 a handwriting input area (i.e., drawing area) in the input method application. As shown in fig. 3, the overlapping area 305 between the foldable area 303 and the handwriting input area 304 is an area where a line is likely to be broken when drawing a graphic, and therefore the overlapping area 305 can be determined as a drawing line breaking-prone area (i.e., a target area). Further, since there may be a problem of screen unevenness also in the vicinity of the overlap area 305, that is, there may be a problem of line breakage due to screen unevenness when lines are drawn in the vicinity of the overlap area 305, the range of the line-drawing easy-to-break area may be expanded on the basis of the overlap area 305, for example, an area where the overlap area 305 is expanded by a preset multiple (a value greater than 1) may be determined as the line-drawing easy-to-break area, as shown at 306 in fig. 3, which reduces the occurrence of a missed judgment. The specific expansion multiple can be determined according to the actual situation of the screen, and the implementation of the application does not limit the specific expansion multiple.
Alternatively, the coordinate region of the drawing line easily-breaking region may be determined based on the screen coordinate system according to a first coordinate region of the drawing region in the screen coordinate system and a second coordinate region of the screen foldable region in the screen coordinate system. For example, if the screen coordinate system uses the lower left corner of the screen as the origin (0, 0), the range of the abscissa of the foldable area 303 is: 1100-1300, the ordinate range is: 0 to 2000; input method application the defined abscissa range of handwriting input area 304: 10-2300, the ordinate range is: 900 — 1500, the abscissa range of the easy-to-break area of the drawn line (i.e. the overlap area 305) can be determined as: 1100-1300, the ordinate range is: 900-1500.
As can be seen from the above, in the embodiment of the present application, it can be determined whether two separate lines are possibly caused by unevenness of the foldable area of the screen based on the easy-to-break area of the drawn line and the drawing track of the line, that is: determining whether the first line and the second line meet a preset condition according to the target area, the drawing track of the first line and the drawing track of the second line, wherein the implementation manner of the determination method may be as follows:
the step of determining whether the first line and the second line satisfy the preset condition according to the target area and the drawing trajectory may include:
acquiring the coordinates of the last first sampling point in the drawing track of the first line and the coordinates of the first second sampling point in the drawing track of the second line; and under the condition that the coordinates of the last first sampling point of the first line and the coordinates of the first second sampling point of the second line are both located in the target area in the drawing area, determining that the first line and the second line meet the preset condition.
The coordinates of the first sampling point are acquired in the drawing process of the first line, and the coordinates of the second sampling point are acquired in the drawing process of the second line.
When a user draws a graph in the drawing area, the electronic equipment can sample the drawn lines to obtain drawing track information of the lines. For example, the drawing trace information obtained by sampling the line a and the line B in fig. 4 may be as follows: [[1019,1211,0],[1079,1204,77],[1141,1166,94],[1184,1147,110],[1200,1148,127],[1200,1148,128],[ -1,0,128],[ -1, -1,128],[1380,1086,283],[1382,1134,345],[1382,1200,361],[1382,1248,377],[1382,1275,394],[1382,1275,395],[ -1,0,395],[ -1, -1,395]]. And every three numbers form a group and respectively represent the x position of an abscissa, the y position of an ordinate and the sampling time t of the touch body contacting the screen. When the touch body is separated from the screen and then contacted again, the division symbols [ -1,0, t ], [ -1, -1, t ] are recorded, and therefore, the sample point coordinates of the line a are the sample point coordinates before the division symbols [ -1,0,128] and [ -1, -1,128] in the drawing trace information, and the sample point coordinates of the line B are the sample point coordinates after the division symbols [ -1,0,128] and [ -1, -1,128] and before the division symbols [ -1,0,395] and [ -1, -1,395] in the drawing trace information. The segmentation symbol can be set according to actual requirements, and is not limited to [ -1,0, t ], [ -1, -1, t ]. The first sampling point coordinate is a coordinate point where the touch body is detected to start to contact the screen, and the sampling time is recorded as 0. The coordinates of the second sampling point are coordinate points of the touch body which is detected to start moving on the screen.
For the line a and the line B adjacent to each other in the drawing time, if the last sampling point coordinate [1200,1148,128] of the line a and the first sampling point coordinate [1380,1086,283] of the line B are both located in the easy-to-break area (the abscissa range is 1000-.
In the embodiment of the present application, in a case that coordinates of a last first sampling point of a first line and coordinates of a first second sampling point of a second line are both located in a target area in a drawing area, it is considered that two separated lines may be caused by unevenness of a foldable area of a screen, and then a first graph and a second graph may be obtained, and a reason for separating the two lines is further determined based on the first graph and the second graph, which may be specifically implemented as follows:
the step of determining that the first line and the second line are separated from each other based on the first graph and the second graph may include:
identifying the first graph to obtain a first identification result; identifying the second graph to obtain a second identification result; and under the condition that the recognition probability of the second recognition result is greater than that of the first recognition result, determining that the first line and the second line are separated from the same line.
In this application embodiment, to the lines of two adjacent separation of drawing time, when confirming whether two line separations are for being obtained by same line separation, can distinguish the figure before and after first line and the second line connection respectively earlier, promptly: when the first line and the second line are not connected (namely, separated), identifying the graph of the drawing area to obtain an identification result (namely, a first identification result); and when the first line is connected with the second line, identifying the graph of the drawing area to obtain an identification result (namely a second identification result). When the electronic device identifies the graph, the final identification result may be determined according to the probability value, for example, the identification result corresponding to the maximum identification probability is used as the final identification result. The greater the recognition probability is, the greater the probability that the graph is the recognition result is, and conversely, the smaller the recognition probability is, the smaller the probability that the graph is the recognition result is, so in the embodiment of the present application, it may be determined whether the two lines are separated by the same line according to the recognition probability of the recognition result.
Assuming that the drawing area only includes a first line and a second line, when the first line and the second line are not connected, recognizing the graph of the drawing area, and obtaining a recognition result as follows: the figure is an exclamation mark, and the corresponding recognition probability is 0.6; when the first line is connected with the second line, the graph of the drawing area is identified, and the obtained identification result is as follows: the figure is the number 1, and the corresponding recognition probability is 0.9, and obviously, the probability that the figure is the number 1 is greater than the probability that the figure is the exclamation mark, that is, the probability that the figure of the drawing area is the number 1 is higher, which indicates that the first line and the second line are separated by the same line.
As an alternative embodiment, at step 102: before a third line formed by connecting the first line and the second line is displayed in the drawing area, the drawing processing method may further include:
and fitting the first line and the second line according to the M sampling point coordinates of the first line and the N sampling point coordinates of the second line to generate a third line.
And the coordinates of the M sampling points of the first line and the coordinates of the N sampling points of the second line are acquired in the drawing process of the lines.
In the embodiment of the application, the first line and the second line can be fitted according to the coordinates of the sampling points of the first line and the second line in the drawing process, so that the two lines are connected to generate the third line. Specifically, the first line and the second line may be fitted through a preset algorithm, where the preset algorithm may include: at least one of a curve fitting algorithm and a uniform resampling algorithm.
For example, the coordinates of the sampling points of the first line and the second line may be spliced together to form a curve, and the blank area between the first line and the second line is filled up by a curve fitting algorithm (e.g., bezier curve fitting algorithm) to obtain a third line. For another example, the first line and the second line may be uniformly resampled according to the coordinates of the sampling points of the first line and the second line, so that a blank area between the first line and the second line is filled, and a third line is obtained.
As can be seen from the foregoing description, in the embodiment of the present application, when it is determined that two lines are separated from each other, the electronic device may automatically perform line repairing, connect the two lines, and display a third line formed after the connection in the drawing area, so that firstly, a drawing error may be compensated, and the integrity of the graph may be improved; secondly, the operation of manually repairing the line by a user can be saved; and thirdly, under the condition that the user does not sense the disconnection of the lines, the lines can be repaired, and the problem that the lines are not used to draw in the drawing process is reduced.
