As mentioned above, the current technical solution of connecting the smart pen to the lan has certain limitations, and the operation is complicated or a screen and a keyboard need to be configured, and the hardware cost is high.
In view of this, embodiments of the present invention provide a method and an apparatus for connecting an intelligent pen to a local area network, a storage medium, and an intelligent pen.
For ease of understanding, the structure of the smart pen is illustrated herein by way of example, and it will be appreciated by those skilled in the art that the smart pen illustrated herein is merely one preferred implementation. Other pens that digitally capture handwriting on a writing medium to restore the handwriting to characters should be considered as smart pens in this invention. Please refer to fig. 1, which is a schematic diagram illustrating a working principle of an intelligent pen according to an embodiment of the present invention.
For convenience of explaining the working principle of the smart pen, components such as a housing, a structural support frame, a circuit board and the like of the smart pen are omitted in fig. 1. Wherein 1001 is a writing medium printed with a dot matrix code; 1002 is a refill of the intelligent pen; 1003 is a lens; 1004 is an image sensor; 1005 is a pixel array of an image sensor; 1006 is the target area of the imaging of the pixel array 1005 on the writing medium through the lens 1003; 1007 is the central origin of the pixel array, which is located on the optical axis of the lens 1003; 1008 is the target point on the writing medium corresponding to 1007; 1009 is the point of contact (i.e., the nib) of the refill with the writing medium; 1010 is an image formed on the image sensor 1004 by virtually imaging the contact point 1009 between the pen core and the writing medium through the lens 1003. Therefore, the handwriting of the smart pen can be restored according to the collection of the pen point coordinates by the image sensor 1004. Wherein, the concrete implementation of the handwriting reduction belongs to the prior art, which is not too much to be said here. Furthermore, the intelligent pen is also provided with a communication module for establishing connection with a local area network.
Fig. 2 is a schematic flow chart of a method for connecting an intelligent pen to a local area network according to an embodiment of the present invention, which specifically includes the following steps:
s1: collecting handwriting of an intelligent pen on a writing medium;
s2: acquiring a local area network name and a local area network key according to the handwriting;
s3: and controlling the intelligent pen to establish connection with the corresponding local area network according to the local area network name and the local area network key.
Specifically, the writing medium is not particularly limited, and may be paper, ceramic, a display screen, or the like. The writing medium is printed with dot codes, and the intelligent pen identifies the pen point or the dot codes near the pen point so as to acquire corresponding coordinates and acquire handwriting.
According to the collected handwriting, image processing or character recognition is carried out on the handwriting, and then the handwriting can be converted into corresponding characters, so that a local area network name and a local area network key are obtained. The local area network name is also called a Service Set Identifier (SSID).
And then, according to the local area network name and the local area network key, the connection between the intelligent pen and the local area network can be established. In a preferred embodiment of the invention, the name of the local area network and the key of the local area network are also stored, so that the connection is automatically made when the smart pen is in the local area network.
In the embodiment of the invention, the handwriting is collected by the intelligent pen so as to restore and obtain the local area network name and the local area network key, so that the intelligent pen can be quickly connected with the corresponding local area network. For the intelligent pen without a screen and a keyboard, the network connection problem can be well solved by adopting the embodiment of the invention, and the intelligent pen is simple to operate and easy to realize. Furthermore, by adopting the technical scheme of the embodiment of the invention, the functions of the intelligent pen can be exerted to the maximum extent, the intelligent pen can be used as a brand-new interactive mode to input the local area network name and the local area network key, unnecessary hardware of a screen and a keyboard can be omitted, and the volume and the cost of the intelligent pen can be reduced. Meanwhile, in order to improve the security, the local area network may be hidden (i.e., SSID broadcast is turned off), and the embodiment of the present invention can access the local area network of this type, so that the application scenario is wide.
Please refer to fig. 3, which is a flowchart illustrating a method for distinguishing a local area network name from a local area network key according to another embodiment of the present invention, including the following steps:
s21: acquiring the name of the local area network according to the first handwriting;
s22: and acquiring the local area network key according to the second handwriting.
Specifically, the handwriting on the writing medium includes a first handwriting located in a first preset area and a second handwriting located in a second preset area. For ease of understanding, referring to FIG. 4, writing medium 10 includes a first preset area 11 and a second preset area 12. The handwriting in the first preset area 11 is the first handwriting, and the handwriting in the second preset area 12 is the second handwriting. In a specific implementation, the handwriting can be distinguished from the first preset area 11 or the second preset area 12 according to the coordinates of the handwriting. Therefore, the collection of the pen point coordinates is used for restoring the handwriting and judging which preset area the handwriting is located in, other judgment logics are not needed to be introduced, and the implementation process is convenient.
Further, referring to fig. 5, in order to improve the accuracy of restoring the local area network name, an embodiment of the present invention further provides a method for obtaining the local area network name, where the method includes:
s211: restoring according to the first stroke in the filling unit to obtain a first character;
s212: and obtaining the name of the local area network according to the first character combination.
Specifically, referring to fig. 6, the first preset area 11 is printed with at least 1 filling unit 13, and the filling unit 13 may be a rectangular frame, a circle, or the like, and the specific shape of the filling unit 13 is not particularly limited in the present invention. In a preferred embodiment, the first stroke in a filling unit 13 is reduced to obtain a first character, which can greatly improve the accuracy of reduction of the first character. Therefore, according to the first strokes in the filling units 13, a plurality of first characters can be restored, and the local area network name can be obtained according to the character combination.
Similarly, referring to fig. 7, in order to improve accuracy of recovering a local area network key, an embodiment of the present invention further provides a method for obtaining a local area network key, where the method includes:
s221: restoring according to the second handwriting in the filling unit to obtain a second character;
s222: and obtaining the local area network key according to the second character combination.
Specifically, with continued reference to fig. 6, the second preset area 12 is printed with at least 1 filling unit 13, and the filling unit 13 may be a rectangular frame, a circle, or the like, and the specific shape of the filling unit is not particularly limited in the present invention. In a preferred embodiment, the second handwriting in a filling unit 13 is restored to obtain a second character, so that the accuracy of restoring the second character can be greatly improved. Therefore, according to the second handwriting in the filling units 13, a plurality of second characters can be recovered, and the local area network key can be obtained according to the character combination.
Please refer to fig. 8, which is a flowchart illustrating a method for combining first characters into a local area network name according to an embodiment of the present invention, including the following steps:
s2121: acquiring coordinates corresponding to the first handwriting according to the dot matrix code;
s2122: determining the position of a first character corresponding to the first handwriting in the local area network name according to the coordinate corresponding to the first handwriting;
s2123: and obtaining the local area network name according to the position combination of the first character in the local area network name.
As mentioned above, the intelligent pen acquires the coordinates corresponding to the first handwriting through the image sensor. In a preferred embodiment, the preset coordinates of each filling unit 13 are different. Therefore, the position of the corresponding first character in the local area network name can be determined according to the coordinate corresponding to the acquired first handwriting, which filling unit 13 the first handwriting is located in. For example, the preset coordinates (xi, yi) are assigned to the 10 filling units of the first preset area in the order of front and rear, where i is 0 to 9. And if the coordinates corresponding to the acquired first handwriting are closest to (x 0, y 0), determining that the first character corresponding to the first handwriting is the first character in the local area network name. According to the principle, the local area network names can be combined.
Similarly, please refer to fig. 9, which is a flowchart illustrating a method for combining second characters into a local area network key according to an embodiment of the present invention, including the following steps:
s2221: acquiring coordinates corresponding to the second handwriting according to the dot matrix code;
s2222: determining the position of a second character corresponding to the second handwriting in the local area network key according to the coordinate corresponding to the second handwriting;
s2223: and obtaining the local area network key according to the position combination of the second character in the local area network key.
The position of the second handwriting in the local area network key can be determined according to the coordinates corresponding to the collected second handwriting, and the filling unit 13 where the second handwriting is located can be determined. For example, the preset coordinates (xj, yj) are assigned to the 10 filling units of the second preset area in the order from front to back, where j is 0 to 9. And if the coordinates corresponding to the acquired first handwriting are closest (x 1, y 1), determining that a second character corresponding to the second handwriting is a second character in the local area network key. According to the principle, the local area network key can be obtained through combination.
The embodiment of the invention also provides another method for acquiring the name of the local area network, which comprises the following steps: and combining to obtain the name of the local area network according to the writing sequence of the first handwriting corresponding to the first character. Specifically, when each first handwriting is collected, a time stamp is allocated to the first handwriting, and therefore the first character obtained through restoration also corresponds to the time stamp. And then, according to the time stamp, combining the first characters according to the sequence of the corresponding first handwriting during writing to obtain the name of the local area network. The user writes the characters in sequence, so the first characters can be accurately combined into the local area network name by adopting the embodiment.
Similarly, local area network keys are also available according to this principle. Specifically, the local area network key is obtained by combining according to the writing sequence of the second handwriting corresponding to the second character. And when each second handwriting is collected, a time stamp is allocated to the second handwriting, so that the restored second character also corresponds to the time stamp. And then, according to the time stamp, combining the second characters according to the sequence of the corresponding second handwriting during writing to obtain the local area network key.
Referring to fig. 10, in order to accurately distinguish case letters from case letters, the filling unit 13 includes a filling subunit 14 therein, and the method includes: and when the first handwriting is reduced into a first character and/or the second handwriting is reduced into a second character, distinguishing the case of the letter according to the position relation between the first handwriting and/or the second handwriting and the filling subunit.
Specifically, if the first stroke is located inside the filling subunit 14, it is recognized as a lower case letter; otherwise, it is recognized as capital letter. For ease of understanding, referring to FIG. 11, a first stroke is recognized as a lower case "W" when it is located entirely inside the filling subunit, and otherwise as an upper case "W". It should be specifically noted that the method can be applied only to confusing letters including c, k, l, m, o, p, s, u, v, w, x, z, etc.
In order to accurately distinguish between Arabic numerals and English letters, distinction can be made by identifiers. The method comprises the following steps: and when the first handwriting is reduced into the first character and/or the second handwriting is reduced into the second character, distinguishing the letters and the numbers according to the identifiers.
Specifically, the identifier may be a line segment, a wave, or the like, and the shape thereof is not particularly limited by the present invention. For easy understanding, please refer to fig. 12, the identifier may be set as a line segment, if it is recognized that the line segment is included below the handwriting, the handwriting is recognized as english letters, otherwise, the handwriting is recognized as arabic numerals. Therefore, handwriting with a line segment is recognized as a lower case letter "q", and handwriting without a line segment is recognized as an arabic numeral "9". It should be noted that the location of the identifier may be located at any position of the filling unit. Of course, this method can be applied only between letters and arabic numbers which are easy to be confused, and there is no need to provide a corresponding recognition method for each letter or arabic number.
Further, other algorithms can be preset to distinguish characters which are easy to be confused. For example, in order to accurately distinguish between the Arabic numeral "0" and the English letter "O", a small horizontal line may be added between the Arabic numeral "0" to avoid confusion with the letter "O". Therefore, the handwriting as shown in fig. 13 is recognized as a lower case letter "O", an upper case letter "O", and an arabic numeral "0", respectively.
It should be noted that the identifier is an additional feature that the user writes on the result of normal writing when writing, and is easy for the smart pen to recognize, rather than being pre-printed on the writing medium.
In an embodiment of the present invention, each time a handwriting in a filling unit is collected, the handwriting is restored to a corresponding character, so as to combine to obtain a local area network name and a local area network key. In the specific implementation, a time threshold value can be preset, and after writing a piece of handwriting, if the next handwriting is not detected in the same preset area after the writing of the next handwriting exceeds the preset time threshold value, the writing is judged to be finished, and the name of the local area network or the secret key of the local area network is obtained.
Referring to fig. 14, in another embodiment of the present invention, a starting unit 15 may be disposed on the writing medium, and when it is detected that the handwriting exists in the starting unit 15, the collected first handwriting is uniformly restored to a first character, and the collected second handwriting is uniformly restored to a second character.
In a preferred embodiment of the present invention, S3 includes:
s31: controlling the smart pen to try to establish connection with a corresponding local area network according to the local area network name and the local area network key;
s32: if the connection is failed to be established, acquiring the first handwriting and/or the second handwriting exceeding the filling unit, and recording as fuzzy handwriting;
s33: analyzing the fuzzy handwriting to obtain the probability weight of each character corresponding to the fuzzy handwriting;
s34: according to the probability weight, modifying a first character corresponding to the fuzzy handwriting in a local area network name and/or a second character corresponding to the fuzzy handwriting in a local area network key into a corresponding character;
s35: an attempt is made to establish a connection with the local area network.
Specifically, when a connection is established with a local area network, if the connection is failed to be established, the possible reason is mainly that the name of the local area network and the key of the local area network are wrong. Therefore, when the connection between the intelligent pen and the local area network fails to be established, the first handwriting and/or the second handwriting, of which part of the handwriting exceeds the filling unit during filling, are acquired and recorded as fuzzy handwriting. And then analyzing the fuzzy handwriting to obtain the probability weight of each character corresponding to the fuzzy handwriting. The analytical algorithm can adopt the existing algorithm, or a chip with a training function is arranged in the intelligent pen, and the probability weights of the characters corresponding to different characteristic diagrams are automatically adjusted according to the writing habits of users.
Based on the processing, the probability weight of each fuzzy handwriting as each character can be obtained. The corresponding characters in the lan name and/or the lan key may then be modified in descending order of probability weight, and a connection with the lan may be attempted again each time the corresponding characters are modified. In this case, only one character in the lan name or only one character in the lan key may be modified at a time, or a plurality of characters may be modified at the same time.
For the sake of understanding, the following exemplary descriptions are made, for example, the local area network name includes 2 fuzzy scripts, which are respectively referred to as a first fuzzy script and a second fuzzy script, and the local area network key includes 1 fuzzy script, which is referred to as a third fuzzy script.
After the analysis, the probability that the first blurred writing is a is 50%, the probability that the first blurred writing is b is 30%, and the probability that the first blurred writing is c is 20%. The probability of the second blurred writing being d is 70%, and the probability of being e is 30%. The probability of the third blurred script being f is 60%, and the probability of being g is 40%.
In one embodiment of the invention, only one character is modified at a time. For example, the characters corresponding to the second fuzzy handwriting and the third fuzzy handwriting are kept unchanged, the characters corresponding to the first fuzzy handwriting are successively modified into a, b and c, and connection with the local area network is tried to be established again after each modification. And modifying characters corresponding to other fuzzy scripts after traversing and modifying the characters corresponding to the first fuzzy script.
In another embodiment of the invention, multiple characters may be modified at a time. For example, the character corresponding to the first blurred writing is modified into a, the character corresponding to the second blurred writing is modified into d, and the character corresponding to the third blurred writing is modified into f.
In another embodiment of the invention, the characters corresponding to each fuzzy writing are arranged and combined to obtain 12 combinations, and the probability weight of each combination is determined. For example, the probability weight of modifying the character corresponding to the first blurred script into a, modifying the character corresponding to the second blurred script into d, and modifying the character corresponding to the third blurred script into f is 50% by 70% by 60%, namely 21%. And then, according to the probability weight of each combination, gradually modifying the local area network name and the local area network key until the connection with the local area network is successfully established or 12 combinations are traversed.
In short, the invention does not limit the number of characters modified each time, and only needs to ensure that each character is modified at least once according to the sequence from large to small according to the probability weight.
In another embodiment of the present invention, S31 is performed a plurality of times before S32 is performed to exclude accidental errors.
The invention is particularly suitable for application scenes needing to use the intelligent pen in a centralized way, such as campus teaching. Since the campus network usually needs to use the school number as the check code of the user identity, as shown in fig. 15, a third preset area 16 may be provided on the writing medium, and the third preset area 16 is printed with a plurality of filling units. Thus, by recognizing the handwriting in the third area 16, the corresponding scholars number can be obtained, which, when establishing a connection with the local area network, is calculated as: the number is used as a check code for identity verification. According to the embodiment of the invention, the network parameter setting can be quickly completed without an additional intelligent terminal or computer, so that the intelligent pen can be added into a campus network and the intelligent pen and student users can be bound conveniently.
