Description

Technical Field

[0002] In recent years, intelligent dictionary pens have emerged in the education industry. Querying unfamiliar Chinese characters and English words is a basic need for primary and middle school students nowadays. By scanning the words they want to know with a dictionary pen, the dictionary pen will display the meanings of the corresponding words on the screen of the dictionary pen, and the operation is relatively simple and fast. The dictionary pen has the function of querying a dictionary. Without manually inputting text, it can directly scan the text through Optical Character Recognition (OCR) technology to query the dictionary and obtain the query result of the text.

Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0057] Figure 3 It is a schematic structural diagram of a dictionary pen scanning device provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0058] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0059] Figure 1 An exemplary system architecture applicable to an embodiment of the present invention is shown, and the system architecture may be a terminal device 100, a server 200, and a dictionary pen 300.

[0060] Among them, the terminal device 100 can be a device such as a mobile phone, a smart watch, a computer, a PAD, etc. that can install application programs. The terminal device 100 can control the dictionary pen 300 by installing the application program of the dictionary pen 300.

[0061] The server 200 is the server to which the application program of the dictionary pen 300 belongs, and is used to receive various instructions from the terminal device 100 and feedback corresponding data, receive various status data of the dictionary pen 300, and store the content scanned and recognized by the dictionary pen 300, etc.

[0062] The dictionary pen 300 can be controlled by the application program installed on the terminal device 100, and can realize the function of scanning and recognizing specified content.

[0063] It should be noted that the structure shown above Figure 1 is only an example, and the embodiments of the present invention do not limit this.

[0064] Figure 2 Exemplarily shows a process of dictionary pen scanning provided by an embodiment of the present invention. This process can be executed by a dictionary pen scanning device, and this device can be a dictionary pen or located in the dictionary pen.

[0065] As Figure 2 shown, this process specifically includes:

[0066] Step 201, the dictionary pen obtains the fingerprint information of the user.

[0067] In the embodiment of the present invention, the dictionary pen is provided with a fingerprint recognition module, which can be a fingerprint recognition sensor. Before obtaining the fingerprint information of the user, it is necessary to first collect the fingerprint information of the user. The dictionary pen can collect the fingerprint information of different users and set usage modes for the fingerprint information of different users. The usage modes include a security mode and a highest privilege mode.

[0068] Among them, the security mode refers to the mode that can only be used after correct fingerprint unlocking, that is, the fingerprint information is successfully recognized to unlock. The highest privilege mode means that the user corresponding to the fingerprint information has the highest usage privilege. Within a preset time period after the fingerprint information with the highest privilege mode is recognized, as long as it is recognized that there is a finger touching and holding the dictionary pen, the scanning mode can be entered without further fingerprint information recognition.

[0069] In addition, in the embodiment of the present invention, the fingerprint information of the user can also identify whether it is a left fingerprint or a right fingerprint, so as to identify whether the user holds the pen with the left hand or the right hand, that is, it can identify users with different hand usage habits.

[0070] To prevent the loss of the dictionary pen, when the number of times the dictionary pen fails to recognize the user's fingerprint exceeds the preset number of times, the function of the dictionary pen is locked, and an alarm message is sent to the application program of the dictionary pen. The alarm message includes the location information of the dictionary pen and the fingerprint information scanned during multiple recognition failures.

[0071] This preset number of times can be set according to experience, such as 3 times, 5 times, etc.

[0072] When the fingerprint recognition fails more than 5 times during the process of the dictionary pen being used by a stranger, an alarm message can be sent to the APP of the dictionary pen, including the GPS positioning of the dictionary pen and the fingerprint information scanned during these 5 times.

[0073] Step 202, after the dictionary pen successfully recognizes the user's fingerprint information and receives the trigger instruction of the word-taking switch of the dictionary pen, it enters the scanning mode.

[0074] Since the dictionary pen is easily mis-triggered due to shaking when placed in a bag or a box, in view of this situation, the embodiment of the present invention realizes that it will enter the scanning mode only after successfully recognizing the user's fingerprint information and receiving the trigger instruction of the word-taking switch of the dictionary pen. In this way, the power consumption caused by the mis-triggering of the dictionary pen can be reduced, thereby increasing the usage duration of the dictionary pen.

[0075] Step 203, the dictionary pen determines the sliding mode of the dictionary pen according to the three-dimensional coordinates of the dictionary pen.

[0076] In order to adapt to the use of users with different hand-use habits, the embodiment of the present invention sets different sliding modes to identify different sliding directions. Specifically, the dictionary pen determines the tilt angle of the dictionary pen according to the three-dimensional coordinates of the dictionary pen. Then, when the dictionary pen determines that the tilt angle of the dictionary pen is tilted to the left and greater than the first threshold, it determines that the sliding mode of the dictionary pen is the left-sliding mode. When the dictionary pen determines that the tilt angle of the dictionary pen is tilted to the right and greater than the second threshold, it determines that the sliding mode of the dictionary pen is the right-sliding mode. The first threshold and the second threshold can be set according to experience.

[0077] That is to say, the three-axis coordinates can be established through the Gsensor to realize the identification of whether it is the left-sliding mode or the right-sliding mode.

[0078] Step 204, the dictionary pen performs scanning and recognition according to the sliding mode of the dictionary pen and the user's fingerprint information.

[0079] Specifically, first, after the scanning pen scans the content specified by the user according to the sliding mode of the scanning pen, scanning information is obtained. Then, the scanning pen selects the image information of multiple frames of the scanning information at a preset interval. Finally, the scanning pen performs image stitching on the selected image information of multiple frames according to the sliding mode of the scanning pen and the fingerprint information of the user, and parses the content in the stitched image. This preset interval can be set according to experience.

[0080] The scanning and recognition process of the scanning pen is the principle of image synthesis after scanning: take each frame in the scanning process at a fixed interval, then stitch each frame into a complete picture, and parse the text according to the word library.

[0081] When stitching the images, when the scanning pen determines that the user is holding the pen with the left hand according to the fingerprint information of the user, it flips the selected image information of multiple frames by a preset angle, and determines the start frame and end frame of the selected image information of multiple frames according to the sliding mode of the scanning pen, and stitches the selected image information of multiple frames according to the start frame and end frame of the selected image information of multiple frames. When the scanning pen determines that the user is holding the pen with the right hand according to the fingerprint information of the user, it determines the start frame and end frame of the selected image information of multiple frames according to the sliding mode of the scanning pen, and stitches the selected image information of multiple frames according to the start frame and end frame of the selected image information of multiple frames.

[0082] This preset angle can be set according to experience, for example, it can be 180 degrees, that is to say, if it is a left-sliding mode, the image information of each frame can be flipped by 180 degrees.

[0083] In addition, when determining the start frame and end frame, if the sliding mode of the scanning pen is the left-sliding mode, the scanning pen determines the image information of the last frame in the selected image information of multiple frames as the start frame, and determines the image information of the first frame in the selected image information of multiple frames as the end frame. If the sliding mode of the scanning pen is the right-sliding mode, the scanning pen determines the image information of the first frame in the selected image information of multiple frames as the start frame, and determines the image information of the last frame in the selected image information of multiple frames as the end frame.

[0084] That is to say, the initial frame and end frame of the jigsaw puzzle are determined by swiping left and right. If swiping from left to right, the start frame is the first frame actually obtained, and the end frame is the last frame. When swiping from right to left, the start frame is the last frame and the end frame is the first frame.

[0085] The above technical solutions solve the problem that the scanning pen does not support swiping from right to left; solve the repeated operation of setting to hold the pen with the left hand or the right hand each time, which is convenient for various users; solve the problem that accidental touch causes increased power consumption.

[0086] The above embodiments show that the dictionary pen obtains the fingerprint information of the user. After successfully recognizing the fingerprint information of the user and receiving the trigger instruction of the word-taking switch of the dictionary pen, it enters the scanning mode. The dictionary pen determines the sliding mode of the dictionary pen according to the three-dimensional coordinates of the dictionary pen, and performs scanning recognition according to the sliding mode of the dictionary pen and the fingerprint information of the user. Starting the scanning can only be achieved through successful fingerprint information recognition and the triggering of the word-taking switch, which can prevent the dictionary pen from being accidentally triggered for automatic scanning, thereby reducing the power consumption of the dictionary. In addition, it can recognize the sliding mode of the dictionary pen to achieve scanning in different directions, which is convenient for users with different hand usage habits and improves the user experience.
