Description

Technical Field

[0001] This application belongs to the field of electronic learning devices, and in particular relates to a reading pen. Background Technology

[0002] Talking pens are a new type of educational tool for children that has become widely popular in recent years. Their principle involves printing an invisible OID code onto regular printed material. The OID codes are arranged according to a pre-designed rule, with different arrangements in different positions. The pen tip has an infrared camera module that captures the OID code on the printed material and converts it into a QR code value. The pen's internal memory pre-stores sound data indexed by the QR code value, allowing the pen to retrieve and play the corresponding sound data based on the obtained QR code value, thus achieving the talking function. However, existing talking pens use a dedicated infrared camera module to photograph the OID code on the printed surface. This infrared camera module is a single, integrated structure, lacking versatility, having high replacement costs, and offering limited functionality. Summary of the Invention

[0003] The purpose of this application is to provide a reading pen that addresses the problems of existing reading pens using a dedicated infrared camera module as an integral structure, resulting in poor versatility, high replacement costs, and limited functionality.

[0004] This application embodiment is implemented as follows: a reading pen includes a pen shell, inside which a main control board and a camera connected to the main control board are disposed. The camera is a wide-angle macro camera, located at one end of the pen tip in the pen shell. The pen tip has a light-transmitting hole for the camera to capture and recognize images, and the distance from the end of the pen tip to the camera is equal to the focal length of the camera.

[0005] In some preferred embodiments of this application, the main control board is provided with a microprocessor, a memory, and a speaker.

[0006] In some preferred embodiments of this application, a power supply is provided inside the pen casing, and the power supply is connected to the main control board to supply power to the main control board.

[0007] In some preferred embodiments of this application, LED lights are symmetrically arranged on both sides of the camera, and the LED lights are connected to the main control board.

[0008] In some preferred embodiments of this application, the camera includes a bracket, an image sensor is fixedly mounted on the bracket, and a lens assembly is provided at the light-intake end of the image sensor.

[0009] In some preferred embodiments of this application, the lens assembly includes a first lens and a second lens, with an infrared filter disposed between the first lens and the second lens.

[0010] In some preferred embodiments of this application, the image sensor, the first lens, the second lens, and the infrared filter are arranged coaxially.

[0011] This application provides a reading pen that uses a common macro wide-angle camera instead of the existing dedicated infrared camera module, offering greater versatility and lower production costs. Furthermore, the macro wide-angle camera allows for image cropping within the central processing unit using algorithms, resulting in a larger amount of labeled information, more accurate information retrieval, and wider applicability.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. The specific implementation of this application is described in detail below with reference to specific embodiments. Figure 1 As shown, a reading pen provided in this application embodiment includes a pen shell 100. A main control board 300 and a camera 400 connected to the main control board 300 are disposed inside the pen shell 100. The camera 400 is a wide-angle macro camera 400. The camera 400 is located at one end of the pen tip of the pen shell 100. The pen tip has a light-transmitting hole for the camera 400 to perform shooting and recognition. The distance from the pen tip to the camera 400 is equal to the focal length of the camera 400.

[0014] In this embodiment, the camera 400 can be a general-purpose macro wide-angle camera used in industries such as dashcams, surveillance equipment, and low-end mobile phone cameras. By using a common macro wide-angle camera to replace the existing dedicated infrared camera module, it offers strong versatility and low production costs. Moreover, the general-purpose macro wide-angle camera can capture images, allowing the reading pen to be used as an image detection device, thus broadening the scope and functionality of the reading pen.

[0015] In some embodiments of this application, the main control board 300 is equipped with a microprocessor 310, a memory 320, and a speaker 350. The pen casing 100 contains a power supply 360, which is connected to the main control board 300 to supply power. In this embodiment, the reading pen's camera 400 captures and identifies a pre-printed OID code on the printed material. The microprocessor 310 inside the pen casing 100 then quickly locates the uniquely bound audio file in the memory 320 based on this unique OID code, and finally plays the sound through the speaker 350.

[0016] In some embodiments of this application, the pen shell 100 is also provided with a button for connecting to the main control board 300, the button being used at least to turn the reading pen on and off.

[0017] In some embodiments of this application, LED lights are symmetrically arranged on both sides of the camera 400, and the LED lights are connected to the main control board 300. In this embodiment, the main control board 300 controls the on / off state of the LED lights 330, which provide stable and sufficient illumination for the camera 400 to supplement light when the ambient light is insufficient, ensuring the normal recognition of the camera 400.

[0018] In some embodiments of this application, such as Figure 2 As shown, the camera 400 includes a bracket 410, on which an image sensor 422 is fixedly mounted. A lens assembly is mounted on the light-inlet end of the image sensor 422, and the lens assembly is slidably mounted on the lens holder 430 of the bracket 410.

[0019] In some embodiments of this application, the lens assembly includes a first lens 441 and a second lens 442, with an infrared filter disposed between the first lens 441 and the second lens 442. The image sensor, the first lens, the second lens, and the infrared filter are coaxially arranged. In this embodiment, light is focused by the optical lens and filtered out by the infrared filter, resulting in light that hits the image sensor 422. An infrared filter is placed in front of the camera 400, allowing infrared light of approximately 850 nm to pass through the filter before entering the camera 400. This physically filters out visible light interference from the environment, creating an imaging environment sensitive only to specific wavelengths of infrared light. This ensures that the camera 400 can capture a high-contrast, stable OID code image, enabling reliable information input. In some embodiments, the camera 400 also includes a circuit board 421, with the image sensor 422 mounted on the circuit board 421, which is connected to the main control board 300. The reading pen of this application uses a common macro wide-angle camera 400, such as those found in dashcams, surveillance equipment, and low-end mobile phone cameras, which offers high versatility and low production costs. Furthermore, in some embodiments of this application, the main control board 300 is also equipped with a communication module 340. After the reading pen recognizes the OID code, it converts it into a QR code value and transmits the QR code value to the user terminal 700 via the wireless communication module. The user terminal 700 locates the corresponding audio file in its storage unit 730 based on the QR code value and sends the audio file back to the reading pen for playback via the speaker 350. Thus, the audio file is not limited by the reading pen's storage capacity, supporting a vast library of books. Specifically, as shown... Figure 3 As shown, in some embodiments, the user terminal 700 is a device equipped with at least a storage unit 730, a communication unit 720, and a display unit 710, such as a computer or a mobile phone. The wireless communication module can be a Bluetooth module or a WiFi module. The principles of Bluetooth and WiFi file transfer are mature technologies and will not be elaborated here.

[0020] like Figure 3As shown, this application embodiment also provides a point-and-read system, including a point-and-read pen and a user terminal 700 that wirelessly communicates with the point-and-read pen; wherein, the point-and-read pen is used to identify the OID code on printed materials and transmit it back to the user terminal 700 through a wireless communication module 340. The user terminal 700 retrieves an audio file stored in its storage unit 730 according to the OID code and transmits the audio file back to the point-and-read pen for playback through its speaker 350. In this embodiment, after the point-and-read pen identifies the OID code, it converts it into a QR code value and transmits the QR code value to the communication unit of the user terminal 700 through the wireless communication module. The user terminal 700 finds the corresponding audio file in its storage unit 730 according to the QR code value and transmits the audio file back to the point-and-read pen for playback through its speaker 350. In this way, the audio file is not limited by the storage capacity of the point-and-read pen and can support a large number of books. Specifically, as shown... Figure 3 As shown, in some embodiments, the user terminal 700 is a device equipped with at least a storage unit 730, a communication unit 720, and a display unit 710, such as a computer or a mobile phone. The wireless communication module can be a Bluetooth module or a WiFi module. The principles of Bluetooth and WiFi file transfer are mature technologies and will not be elaborated here.

[0021] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
