Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a flow diagram of a text creation method provided in an embodiment of the present invention includes:
s101, obtaining a standard font of a character to be created, splitting the standard font according to writing strokes, and obtaining independent standard strokes forming the standard font.
And S102, creating characters to be created according to the writing path of each standard stroke.
For step S101, in a preferred embodiment, the standard font may be, but is not limited to, a font with a certain width, which is obtained from data on the internet or various types of copybooks, and may be a regular font, a song style, a rule script, a black body, a song imitation, and the like.
Fig. 3 shows a standard font of a chinese character "ten", and in an embodiment, the chinese character "ten" is taken as an example for specific description, but it should be noted that the standard font is not limited to "ten", and the standard chinese character "ten" mentioned here is only for better explaining the present solution and does not play a limiting role.
When the character to be created is the Chinese character 'ten', firstly, the standard font of the Chinese character 'ten' is obtained, then the standard font 'ten' is split according to the stroke of writing the 'ten', and the standard font 'ten' is split into a horizontal part (one) and a vertical part (l).
For step S102, in a preferred embodiment, writing each stroke of the character to be created in sequence according to the stroke writing sequence of the standard font and the writing path of each standard stroke, and finally creating the character to be created. In the above example, the writing order of the standard font "ten" is to write a horizontal stroke first and then a vertical stroke, so when creating the character to be created, firstly, a horizontal stroke is written according to the writing path of the standard stroke "horizontal stroke", then, a vertical stroke is written according to the writing path of the standard stroke "vertical stroke", and finally, the creation of the character "ten" to be created is completed.
Of course, in another preferred embodiment, the strokes may be written out of writing order. That is, according to the writing path of each standard stroke, each stroke of the character to be created is written in any order, and finally the character to be created is created. The above example may write a horizontal bar first and then a vertical bar.
It should be added that, in an optional embodiment, before creating a character to be created according to the writing path of each standard stroke, the standard font of the character to be created is taken as a reference base map, the split standard strokes are placed in an overlapping manner according to the positions of the corresponding strokes on the reference base map, and during writing, writing is performed according to the placement positions of the standard strokes, so that the structure of the original standard font is retained, and the position deviation of part of the strokes during writing is avoided.
In a preferred embodiment, the writing is performed by a robotic pen while writing the text to be created.
The following describes how to obtain the writing path of each standard stroke in detail:
as shown in FIG. 2, the method for creating the writing path of each standard stroke comprises the following steps:
step S201, obtaining an edge contour of a standard stroke, and dividing the edge contour into two combined paths, namely a first combined path and a second combined path, by using a stroke-down point of the standard stroke and a stroke-lifting point of the standard stroke.
Step S202, nodes are respectively established on the first combination path and the second combination path, and a plurality of first combination nodes and a plurality of second combination nodes are obtained.
Step S203, connecting the first combination nodes and the second combination nodes one by one along the direction from the pen-down point to the pen-up point or along the direction from the pen-up point to the pen-down point to obtain a plurality of connecting line segments, and extracting the middle points of the connecting line segments to obtain a plurality of writing nodes.
And step S204, obtaining the writing path of the standard stroke according to each writing node.
For step S201, the edge contour of the standard stroke needs to be obtained first, and in a preferred embodiment, the obtaining of the edge contour of the standard stroke specifically includes:
and drawing along the shape of the standard stroke to obtain the edge profile, wherein the starting point is used as the starting point, the stroke lifting point is used as the end point, the starting point is divided into two directions according to the shape of the standard stroke, and the ending point is ended. As shown in fig. 5, it is an edge contour diagram of a standard stroke of a Chinese character "ten", where point a is a stroke starting point (starting point) of a standard stroke "horizontal", point B is a stroke lifting point (ending point) of the standard stroke "horizontal", point C is a stroke starting point (starting point) of a standard stroke "vertical", point D is a stroke lifting point (ending point) of the standard stroke "vertical", as can be seen from fig. 5, when the edge contour of the standard stroke 'horizontal' is obtained, the line is drawn from the point A along the upper and lower directions of the point A simultaneously and along the shape of the standard stroke 'horizontal' until the point B is finished, at this time, the point A and the point B divide the contour of the standard stroke 'horizontal' into an upper and lower section combined path, when the standard stroke 'vertical' is obtained, the line is drawn from the point C along the left and right directions of the point C simultaneously along the shape of the standard stroke 'vertical' until the point D is finished, and at the moment, the point C and the point D divide the standard stroke 'vertical' into a left and right end combined path.
It should be noted that the edge contour of the standard stroke is not limited to be obtained in the above manner, for example, in another preferred embodiment, the edge contour may also be obtained by using the pen-down point as the end point, using the pen-up point as the start point, starting from the start point to the end point in two directions according to the shape of the standard stroke, and tracing along the shape of the standard stroke.
In addition, in another optional embodiment, the edge contour of the standard stroke may be directly extracted by directly using the existing edge detection technology, and then the pen placing point and the pen lifting point of the standard stroke are calibrated, so as to divide the edge contour of the standard stroke into two sections of combined paths.
For step S202, in a preferred embodiment, nodes are respectively established on the first combined path and the second combined path, specifically:
and establishing the same number of nodes on the first combined path and the second combined path by taking the pen-down point as a path starting point and taking the pen-up point as a path end point. As shown in fig. 6, a plurality of nodes of the same number are arranged on the edge contour of the standard stroke "vertical" of the standard chinese character "ten".
In a preferred embodiment, the number of the nodes is set according to a standard font, and then the size of the image is set according to a certain proportion, such as: in a font image of 300 × 300px, 30 nodes may be set to be respectively established in the first combining path and the second combining path.
In another preferred embodiment, the pen-down point may be used as a path end point, the pen-up point may be used as a path start point, and nodes may be respectively established on the first combined path and the second combined path according to a preset distance.

Similarly, the nodes on the left and right combined paths of the standard stroke vertical are connected, and then a plurality of writing nodes of the standard stroke vertical are obtained in the same way.
It should be noted that: the direction from the lower stroke point to the pen lifting point is the writing direction of the corresponding stroke, and the direction from the pen lifting point to the lower stroke point is the opposite direction to the writing direction of the corresponding stroke. In actual operation, one of the ways may be arbitrarily selected, and the first combining path node and the second combining path node are connected in a one-to-one correspondence manner.
For step S204, in a preferred embodiment, a writing path of the standard stroke is obtained according to each writing node, specifically:
and sequentially connecting the writing nodes along the direction from the pen-down point to the pen-up point or along the direction from the pen-up point to the pen-down point to obtain a writing path of the standard stroke. As shown in FIG. 7, according to the above method, the ten-stroke path of the Chinese character can be finally obtained.
In another preferred embodiment, the writing path of the standard stroke is obtained according to each writing node, specifically:
and sequentially connecting each writing node, the pen placing point and the pen lifting point along the direction from the pen placing point to the pen lifting point or along the direction from the pen lifting point to the pen placing point to obtain a writing path of the standard stroke.
In another preferred embodiment, the writing path of the standard stroke is obtained according to each writing node, specifically:
and sequentially connecting each writing node and the pen lifting point along the direction from the pen lowering point to the pen lifting point or along the direction from the pen lifting point to the pen lowering point to obtain a writing path of the standard stroke.
In another preferred embodiment, the writing path of the standard stroke is obtained according to each writing node, specifically:
and sequentially connecting each writing node and the pen-down point along the direction from the pen-down point to the pen-up point or along the direction from the pen-up point to the pen-down point to obtain a writing path of the standard stroke.
The writing path of the standard stroke can be obtained through the various ways.
Finally, as shown in fig. 4 and 8, in the prior art, the characters to be created by the character creating method provided by the embodiment of the present invention are compared with the characters to be created obtained by performing the stroke according to the outer edge of the font, so that the characters to be created by the character creating method provided by the embodiment of the present invention are more in line with the writing habit of human beings, and the total writing path is shorter, so that the robot has higher efficiency when holding a pen for writing.
It should be noted that, when each font to be created is created, the writing path of each standard stroke of the font to be created can be obtained immediately according to the method from step S201 to step S204.
In order to further improve the writing efficiency, in another preferred embodiment, all basic strokes of a Chinese character and writing paths of corresponding standard strokes may be stored in a database in advance, when creating a character to be created, the method of step S101 is firstly followed to obtain each standard stroke, then the writing paths of the corresponding strokes are directly searched in the database, and then the writing paths of all the strokes are sent to the robot, and the robot holds the pen to write. Therefore, the operations from the step S201 to the step S204 do not need to be repeated again, and the writing efficiency of the robot is further improved.
