Description

Technical Field

[0001] The present invention relates to the technical field of scanning pens, and in particular to a scanning pen and a global scanning triggering method for facilitating result checking. Background Art

[0002] Currently, scanning pens that support intelligent recognition and translation are very popular among parents and children. When encountering words they don’t understand, they only need to scan to know the meaning, which is very conducive to learning and communication. However, most of the scanning pens on the market can only rely on pressing one end of the stylus tip to trigger recognition. Each recognition requires dragging the pen tip to scan, and the scanning area is scanned with the dragging position. It is difficult to perform a global scan (for example, recognizing a whole page of a book), which reduces the user experience.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0004] The purpose of the present invention is to provide a solution that can enrich the usage scenarios of the scanning pen in view of the deficiencies existing in the above-mentioned background technology, so as to achieve a leap-forward improvement in user experience.

[0005] In order to achieve the above-mentioned object, the present invention provides a scanning pen for easy access to results, including a scanning pen body and a camera module, wherein the camera module can realize local scanning and large-scale global scanning, and also includes a display module, wherein the display module is rotatably connected to the scanning pen body through a rotating structure, and can display scanning information.

[0006] Furthermore, the camera module includes a local camera and a global camera, the local camera realizes local scanning, and the global camera realizes global scanning.

[0007] Furthermore, the scanning pen body includes a pen body and a pen head arranged at the bottom of the pen body, the local camera is connected to the pen head, and the global camera is connected to the pen body or the display module.

[0008] Furthermore, a display module accommodating area is provided on the scanning pen body for accommodating the display module, and the display module can rotate relative to the display module accommodating area under the action of the rotating structure.

[0009] Furthermore, the display module accommodating area is a accommodating slot, and the display module is a display screen.

[0010] Further, when the display module rotates to be parallel to the central axis of the scanning pen body, the display module can block and cover the global camera to protect the global camera.

[0011] Further, it further includes a rotation detection module, which detects the rotation state of the display module and triggers the opening or closing of a preset function according to the rotation state.

[0012] Further, the rotation detection module includes a permanent magnet / Hall circuit arranged in the display module and a Hall circuit / permanent magnet correspondingly arranged in the accommodation area of the display module. When the display module rotates to different angles, the Hall circuit generates corresponding voltages to detect the rotation angle of the display module.

[0013] Further, the rotation detection module includes a gyroscope arranged inside the display module, and different directions of rotation data will be generated when the display module rotates.

[0014] Further, the electrical connection method between the display module and the scanning pen body includes wired connection and / or wireless connection, and the wireless connection includes one or several combinations of wifi connection, Bluetooth connection, and NFC connection.

[0015] The present invention also provides a global scanning trigger method, which triggers entering the global scanning mode when the display module rotates to a preset angle.

[0016] The present invention also provides another global scanning trigger method, which continuously rotates the display module back and forth within a preset period to enter the global scanning mode.

[0017] The present invention also provides another global scanning trigger method, which sets different rotation angles corresponding to different numbers, rotates the display module to different angles in sequence, and inputs the global scanning mode password to trigger entering the global scanning mode.

[0018] After entering the global scanning mode through the above method, when the time in the unused state exceeds the preset safety time threshold, the user is reminded and the global scanning mode is exited.

[0019] Among them, the unused state can be confirmed by whether the image collected by the camera module changes, or whether there is a scanned object supported by the target program, or whether there is an effective state change in the recognition target.

[0020] The above solution of the present invention has the following beneficial effects:

[0021] In the scanning pen provided by the present invention, the camera module can perform local scanning to complete functions such as line-by-line recognition of words, phrases, and sentences, and can also perform global scanning to capture images of the entire page of books, test papers, etc., and complete functions such as fingertip reading and intelligent marking. The display module is rotatably connected to the main body of the scanning pen through a rotating structure. During local scanning, the user can slide the pen tip on the target scanning area just like operating a conventional scanning pen. When global scanning is required, the user only needs to rotate the display module to open the shooting angle in front of the global camera, ensuring that the global camera is at a better scanning height and angle when the scanning pen is held or fixed on the bracket, so as to successfully complete global scanning and perform global recognition or fingertip reading, etc., which is convenient to operate and improves the user experience. In addition, when performing global scanning, there is more content displayed on the display module. By rotating and horizontally expanding the display module, it is easier to view the displayed content, improving the convenience and interest of use.

[0022] Other beneficial effects of the present invention will be described in detail in the subsequent specific implementation part. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1:

[0031] As Figures 1 - 3 shown, Embodiment 1 of the present invention provides a scanning pen that facilitates the review of results, including a scanning pen body and a camera module. Among them, the camera module includes a local camera 1 and a global camera 2. The local camera 1 realizes local scanning and completes functions such as line-by-line recognition of words, phrases, and sentences. The global camera 2 realizes large-range global scanning and can capture images of the entire page of books, test papers, etc., and completes functions such as fingertip reading and intelligent correction. In this embodiment, the scanning pen body includes a pen body 3 and a pen tip 4 provided at the bottom of the pen body 3. The local camera 1 is connected to the pen tip 4, and the global camera 2 is connected to the pen body 3.

[0032] At the same time, the scanning pen further includes a display module 5. The display module 5 is rotatably connected to the scanning pen body through a rotating structure 6 and can display scanning information, that is, the images scanned by the local camera 1 or the global camera 2 are displayed in real time. The user can adjust the scanning angle, scanning range, etc. according to the images on the display module 5. When it is determined that the range captured by the current camera is the target scanning area, an input signal can be confirmed through a button, etc. The main control performs OCR recognition on the images scanned by the camera and can display the recognition results on the display module, facilitating the user's review.

[0033] During local scanning, the display module 5 is rotated to be parallel to the central axis of the pen body 3. The user can slide the pen tip 4 on the target scanning area for scanning just like operating a conventional scanning pen. When global scanning is required, the user only needs to rotate and unfold the display module 5 to open the shooting angle in front of the global camera 2, ensuring that the global camera 2 is at a better scanning height and angle when the scanning pen is held by hand or fixed on a bracket, so as to successfully complete global scanning, perform global recognition or fingertip reading, etc. The operation is convenient and improves the user experience. In addition, when performing global scanning, there is more content displayed on the display module 5. By rotating and horizontally unfolding the display module 5, it is easier to view the displayed content. Therefore, the scanning pen provided in this embodiment can not only adjust the angle of the display module 5 by rotation to more conveniently view the results, but also can smoothly perform the relevant functions of global scanning after rotating the display module 5, improving the convenience and interest of the operation.

[0034] In this embodiment, a display module accommodating area 7 is provided on the scanning pen body, specifically an accommodating groove, for accommodating the display module 5. The rotating structure 6 is arranged at the bottom of the accommodating groove, and the display module 5 can rotate relative to the display module accommodating area 7 under the support of the rotating structure 6. In this embodiment, the display module 5 is a display screen.

[0035] To maintain the position stability of the display module 5 after rotation, a fixing structure is also provided in this embodiment. Through the fixing structure, the display module 5 is kept in the corresponding position after rotation to ensure the stability after the global scanning function or local scanning function is triggered. Among them, the fixing structure includes but is not limited to a magnetic structure, etc.

[0036] As a further improvement, when the display module 5 rotates to be parallel to the central axis of the scanning pen body, that is, when the display module is folded, it can cover and shield the global camera 2 to protect the global camera 2 and prevent the global camera 2 from being easily damaged due to long-term exposure. On the other hand, it can make the scanning pen default to work in the local scanning mode.

[0037] In this embodiment, the scanning pen further includes a rotation detection module. The rotation detection module can detect the rotation state of the display module 5 and trigger the opening or closing of a preset function according to the rotation state. The rotation detection module includes a permanent magnet / Hall circuit arranged in the display module 5 and a Hall circuit / permanent magnet correspondingly arranged in the display module accommodating area 7. Thus, when the display module 5 rotates to different angles, the Hall circuit generates corresponding voltages to detect the rotation angle of the display module 5 and feedback signals.

[0038] In other embodiments, the rotation detection module can also be a gyroscope arranged inside the display module 5. When the display module 5 rotates, different directions of rotation data are generated by the gyroscope, and the rotation angle of the display module 5 can also be detected and obtained.

[0039] Of course, other detection methods can also be adopted, and no specific restrictions are imposed here.

[0040] In this embodiment, the electrical connection mode between the display module 5 and the scanning pen body includes wired connection and / or wireless connection. The wireless connection includes, but is not limited to, one or several combinations of wireless near-field communication connections such as wifi connection, Bluetooth connection, and NFC, making the communication between the display module 5 and the main control inside the scanning pen body reliable, and relying on the rotation state of the display module 5 to switch between the local scanning mode and the global scanning mode, etc.

[0041] Embodiment 2:

[0042] Embodiment 2 of the present invention provides a global scanning trigger method, which is applied to the scanning pen in Embodiment 1. In this method, when the display module 5 is rotated to a preset angle, it triggers to enter the global scanning mode. For example, when rotated 90 degrees clockwise or counterclockwise, it is the conventional local scanning mode, and at this time, it does not enter the global scanning mode. When rotated 450 degrees, that is, when rotated one full circle and then rotated 90 degrees, it can trigger to enter the global scanning mode. Using this method makes it possible for the user to horizontally place the display module 5 in the local scanning mode. In addition, it can also prevent the user from accidentally operating and entering the global scanning mode.

[0043] In other embodiments, the global scanning trigger method can also be to continuously rotate the display module 5 back and forth within a preset period to enter the global scanning mode. For example, in the normal state, continuously rotate 90 degrees clockwise within 5 seconds, then rotate 90 degrees counterclockwise, and then rotate 90 degrees clockwise, and trigger to enter the global scanning mode through multiple back-and-forth rotations within the preset time.

[0044] In other embodiments, the global scanning trigger method can also be to set different rotation angles corresponding to different numbers, and rotate the display module 5 to different angles in sequence, and input the global scanning mode password to trigger to enter the global scanning mode. For example, rotating 90 degrees clockwise corresponds to the digital signal 0, rotating 180 degrees corresponds to the digital signal 1, rotating 270 degrees corresponds to the digital signal 2, rotating 360 degrees corresponds to the digital signal 3, etc. When the display module 5 rotates to the corresponding angle and stays for a preset time, input the corresponding digital signal. When all the digital signals are correct, unlock and enter the global scanning mode. Among them, the relationship between the digital signal and the rotation angle is not specifically restricted, and the number of set digital signals is also not restricted.

[0045] In this embodiment, a safety time threshold is further set. After entering the global scanning mode, when the unused state time exceeds the preset safety time threshold, the user is reminded and the global scanning mode is exited to save power consumption.

[0046] Among them, the unused state can be confirmed by whether the image collected by the camera module changes, or whether there is a scanned object supported by the target program (for example, when no homework is detected in the recognition target for a preset time during the homework recognition process), or whether there is an effective state change in the recognition target (for example, whether the scanned book or test paper is effectively turned over).

[0047] Further, when the scanning pen enters the unused state and reaches the preset second time threshold, the user can be further reminded to put away the scanning pen and restore it to the normal state of local scanning. When the user manually puts away the display module 5 to the normal state of local scanning, the global scanning mode is exited.

[0048] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
