Description

Technical Field

[0001] The utility model relates to the technical field of palm brushing, and specifically, to a palm brushing device with supplementary lighting. Background Art

[0002] As a new biometric technology, the palm brushing device has broad application prospects. Its application fields include but are not limited to the following aspects:

[0003] Access control system: In places such as office buildings, residential communities, and parks, the palm brushing device can be used in the access control system to conduct efficient and secure identity verification and management of people entering and leaving. Through palmprint and palm vein recognition technologies, it ensures that only authorized personnel can enter and leave specific areas.

[0004] Mobile payment: Palm brushing payment is the application of the palm brushing device in the payment field. Users only need to place their palms on the palm brushing device to achieve fast and secure payment operations. This payment method eliminates the need to carry a mobile phone or wallet, improving the convenience and security of payment.

[0005] Smart campus: On campus, the palm brushing device can be used for identity verification and attendance management of students, teachers, and logistics staff. By brushing the palm, the identity of people entering and leaving the campus can be verified, and attendance information can be accurately recorded.

[0006] Digital healthcare: Inside hospitals, the palm brushing device can be used in scenarios such as key drug management, doctor and nurse on-duty attendance, etc. In addition, it can also be used for patient identity verification and medical record management, as well as registration and payment, improving the efficiency and security of medical services.

[0007] New retail: In retail places such as shopping malls or supermarkets, customers can use the palm brushing device for membership registration and consumption payment to enjoy a more convenient shopping experience.

[0008] Smart city: In the construction of a smart city, the palm brushing device can provide more efficient and secure access management for public facilities such as libraries and stadiums. At the same time, it can also be used in scenarios such as the city's all-in-one service and bus payment systems to enhance the intelligent level of urban management.

[0009] In practical applications, the palm brushing device usually combines visible light supplementary lighting and infrared supplementary lighting technologies to ensure high-quality palmprint and palm vein images can be obtained under various lighting conditions. At the same time, the palm brushing device is also equipped with advanced image processing algorithms and recognition algorithms, which can quickly and accurately analyze and process the collected images, thereby achieving efficient and secure identity verification and payment operations.

[0010] In the recognition process of the palm brushing device, in order to improve the accuracy and stability of recognition, supplementary lighting technology is usually adopted. Supplementary lighting technology mainly includes two types: visible light supplementary lighting and infrared supplementary lighting:

[0011] Visible light supplementary lighting: Supplementary lighting of the palm is carried out through a visible light source to make features such as palm prints and palm veins more clearly visible. This supplementary lighting method is suitable for scenarios with relatively dim light or a relatively dark palm color.

[0012] Infrared supplementary lighting: Supplementary lighting of the palm is carried out using an infrared light source. Since infrared light can penetrate the skin surface layer, internal features such as palm veins can be captured more accurately. Infrared supplementary lighting technology is of great significance for improving the accuracy and stability of recognition.

[0013] To obtain a clear palm image, it is often necessary to obtain a uniform supplementary lighting effect. In the prior art, a uniform light ring is often used for uniform light processing. However, when a palm brushing device is provided with components such as a display screen, due to connections and the like, the uniform light ring cannot perform uniform supplementary lighting.

[0014] The disclosure of the above background technical content is only used to assist in understanding the inventive concept and technical solution of the present utility model, and it does not necessarily belong to the prior art of this patent application. Without clear evidence indicating that the above content was publicly available on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and inventiveness of this application. Summary of the Utility Model

[0015] Therefore, the present utility model proposes a palm brushing device with supplementary lighting, adopting a connecting component made of a transparent material, so that the influence of the connecting component on the light path is minimized, thereby making the uniform light effect of the uniform light ring the best, which is conducive to obtaining a clearer palm image.

[0043] A palm - brushing device with supplementary lighting provided by an embodiment of the present utility model aims to solve the problems existing in the prior art.

[0044] The following will specifically describe in detail the technical solutions of the present utility model and how the technical solutions of this application solve the above technical problems. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in some embodiments. The embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0045] The present utility model adopts a connection component made of a transparent material, which minimizes the influence of the connection component on the light path, thereby achieving the best light homogenization effect of the light homogenizing ring and facilitating the acquisition of a clearer palm image.

[0046] Figure 1 FIG. shows a structural schematic diagram of a palm brushing device with supplementary lighting in an embodiment of the present utility model. As Figure 1 shown, a palm brushing device with supplementary lighting in an embodiment of the present utility model includes:

[0047] A display screen 1, including a protruding connection component 4.

[0048] Specifically, the connection component 4 is made of a transparent material. The display screen is the main interface for user-device interaction, used to display information, operation prompts, recognition results, etc. In the palm brushing device, it can also display palm images or animations during the recognition process to enhance user perception. A sensor is also provided inside or below the display screen for collecting palm signals.

[0049] The connection component is for achieving the stable connection and information communication between the display screen and the peripheral structure (such as the light homogenizing ring, bracket, etc.), while maintaining a certain light transmittance. Using a transparent material, such as glass or plastic with a high light transmittance, can ensure that after the light from the supplementary light passes through the light homogenizing ring, it can still clearly illuminate the palm without affecting the normal display of the display screen. The connection component being made of a transparent or semi-transparent material is to maximize the supplementary lighting effect, reduce the loss and scattering of light during propagation, and at the same time not affect the user's viewing of information through the display screen.

[0050] When the connection component includes components such as wires, it is required that except for the wires, the rest of the connection component is a transparent insulator to ensure the maximum light passing rate. At the same time, the multiple wires in the connection component are evenly distributed in a dispersed manner so that the wire area in a preset area of the cross-section of the connection component is the same. For example, the cross-sectional area of the connection component is 10 cm 2 , there are 10 wires in total and their cross-sectional areas are equal, then the distribution of the wires makes it such that any 1 cm 2 area has only one wire. It should be noted that as Figure 2 shown, the distribution of the wires is not in a matrix distribution, but in a dispersed and staggered distribution so that the wire area in any preset area is the same. The preset area can be in any position, either a horizontal or a vertical closed area.

[0051] The uniform light ring 2 is located outside the display screen 1 and surrounds the display screen 1.

[0052] Specifically, the uniform light ring is located outside the display screen, closely surrounding and enclosing the display screen. Its main function is to evenly diffuse the light emitted by the supplementary light lamp to the entire palm recognition area. This can ensure that all parts of the palm can receive uniform and sufficient light, improving the quality of image acquisition and the recognition accuracy. The inside of the uniform light ring contains special reflective or scattering materials, which can effectively disperse the light and avoid obvious light spots or shadows, thus achieving uniform light distribution. Its design needs to consider the physical characteristics of light propagation to achieve the best lighting effect. The uniform light ring has a symmetrical structure, such as a circular ring, a quadrilateral, etc. The light emitted by the uniform light ring is in the same direction as the orientation of the display screen.

[0053] The supplementary light lamp 3 is located below the uniform light ring 2 and emits light towards the uniform light ring 2.

[0054] Specifically, the supplementary light lamp is located below the uniform light ring and is a key component for providing light source. It emits light towards the uniform light ring, and through the diffusion effect of the uniform light ring, illuminates the palm recognition area. For a palm-sweeping device, the role of the supplementary light lamp is particularly important. When the palm approaches the palm-sweeping device, it will block the external light, making the palm area darker, while the supplementary light lamp can significantly improve the clarity and contrast of image acquisition and reduce the misrecognition rate.

[0055] There are various types of supplementary light lamps, including LED lamps, fluorescent lamps, etc. Preferably, the supplementary light lamp is an LED lamp, which has the advantages of small volume, low power consumption, long lifespan, adjustable brightness, etc.

[0056] In some embodiments, in order to adapt to different lighting environments and recognition requirements, the brightness and color temperature of the supplementary light lamp need to have adjustable functions.

[0057] In some embodiments, as shown in Figure 3 Figure 3 or 4, the connecting component is located inside or below the uniform light ring. The connecting component is not only the connection point between the display screen and the peripheral structure, but also participates in the light transmission process. First of all, the connecting component ensures that the display screen can be firmly installed on the device while maintaining a tight fit with the uniform light ring. Secondly, the connecting component is made of a transparent or semi-transparent material and is located on the light path of the uniform light ring, and can also play a role in assisting light diffusion, helping the light to irradiate the palm recognition area more evenly. Since the connecting component needs to meet the requirements of both structural strength and light transmittance, high-transmittance, high-strength and durable materials are usually selected, such as high-transmittance glass, special engineering plastics or composite materials, etc.

[0058] In some embodiments, the central axis of the light emitted by the fill light is perpendicular to the display screen. The central axis direction of the light of the fill light is perpendicular to the plane of the display screen. This perpendicular emission method helps to ensure that the light can cover all parts of the palm to the greatest extent, reducing shadows or light spots caused by angular deviation. The perpendicularly emitted light is more likely to achieve uniform distribution through the diffusion effect of the light homogenizing ring. The internal reflecting surface or scattering material of the light homogenizing ring can effectively disperse the light, so that the palm recognition area is evenly and softly illuminated. The light emitted by the fill light being perpendicular to the display screen is an effective design method in the palm-sweeping device, which can improve the recognition accuracy, reduce shadows and light spots, and optimize the user experience.

[0059] In some embodiments, the connecting component protrudes in a direction parallel to the surface of the display screen. The connecting component does not protrude perpendicular to the surface of the display screen, but protrudes outward in a direction parallel to the surface of the display screen. This means that the connecting component extends on the same horizontal plane as the edge part of the display screen, without increasing the thickness of the device in the vertical direction. The protruding connecting component can, to a certain extent, protect the display screen from direct external impact or scratching, especially when the device is accidentally dropped or collided. Through the close connection with the peripheral structure, the protruding connecting component helps to enhance the structural stability of the entire device and reduce deformation caused by vibration or external force.

[0060] In some embodiments, there is a light homogenizing component inside the connecting component. The main function of the light homogenizing component is to homogenize the light emitted by the fill light, ensuring that the light presents a uniform and soft illumination effect when propagating to the palm recognition area. This helps to reduce problems such as shadows and light spots caused by uneven light, and improve the quality of image acquisition and recognition accuracy. The material of the light homogenizing component needs to have good light transmittance and scattering properties to ensure that the light can pass through smoothly and be evenly distributed. Common materials include optical glass, optical plastics, and special scattering materials, etc. Preferably, the material of the connecting component is the same as that of the light homogenizing ring.

[0061] In some embodiments, at least part of the light emitted by the fill light passes through both the connecting component and the light homogenizing ring. The light of the fill light is emitted around the display screen and evenly irradiates the palm. When the connecting component only exists at some edges of the display screen, rather than all edges, part of the light emitted by the fill light passes through the connecting component and the light homogenizing ring and irradiates the palm. When the connecting component is located at all edges of the display screen, part or all of the light emitted by the fill light passes through the connecting component and the light homogenizing ring and irradiates the palm. When the connecting component is located at all edges of the display screen, that is, when the connecting component surrounds the display screen, the light of the fill light is processed by the connecting component and the light homogenizing ring to be more uniform and maintain good consistency at different edges of the display screen.

[0062] In some embodiments, the thickness of the connecting component is a fixed value. When the thickness of the connecting component is a fixed value, it means that during the entire design or manufacturing process, the thickness dimension of this component remains unchanged and does not change with the variation of other factors (such as position, force application conditions, etc.). A connecting component with a fixed thickness is easier to control the size and precision during the manufacturing process, thereby simplifying the production process. This helps to reduce the manufacturing cost and improve the production efficiency. Since the thickness of the connecting component is fixed, the structural consistency of each component can be ensured. This helps to maintain the stability and reliability of the overall performance of the device. The connecting component with a fixed thickness is more convenient for installation and maintenance. Because they have unified sizes and specifications, they can be more easily matched and replaced with other components. Consistent connecting components contribute to the consistency of the optical path, making the emitted optical path more uniform. Stable connecting components help to maintain the stability of the overall structure of the device, thereby contributing to improving the quality of image acquisition and the recognition accuracy. Because a stable structure can reduce problems such as image blurring and distortion caused by vibration or loosening.

[0063] In some embodiments, the power of the part of the supplementary light located below the connecting component is greater than that of other parts. The supplementary light is designed as at least two independent light-emitting regions, and the power and brightness of each region can be independently controlled. By adjusting the power setting of the region below the connecting component, an increase in the power of this region can be achieved. In addition to power adjustment, the propagation and distribution of light can also be optimized through optical design. For example, optical elements such as reflectors or lenses are arranged below the connecting component to direct more light to the palm recognition area. By increasing the power of the supplementary light part below the connecting component, it can be ensured that the palm recognition area receives brighter and more uniform illumination, thereby improving the quality of image acquisition and the recognition accuracy. Since the connecting component may block or scatter part of the light, increasing the power of the supplementary light below it can compensate for this loss and ensure that the light can fully illuminate the palm recognition area. At the same time, this design also helps to reduce shadows and light spots caused by uneven light, improving the clarity and contrast of the image. During the palm brushing recognition process, it is crucial to quickly and accurately capture the palm image. By enhancing the power of the supplementary light below the connecting component, the image acquisition time can be shortened, the recognition efficiency can be improved, and thus the user experience can be enhanced.

[0064] In some embodiments, the length of the connecting component is greater than 2 / 3 of the width of the uniform light ring. The longer connecting component provides more stable support for the uniform light ring. During the use of the device, this stability helps to reduce deformation or displacement caused by vibration or external forces, thereby ensuring that the uniform light ring can maintain its predetermined position and shape, and further ensuring the uniformity and stability of the illumination. The length of the connecting component directly affects the mechanical structure and stability, and also affects the uniformity of the illumination. This embodiment can improve the uniformity of the illumination.

[0065] In some embodiments, the light of the supplementary light lamp below the connecting component all passes through the connecting component. The connecting component is long and completely covers the light path of the supplementary light lamp. Since the light of the supplementary light lamp can pass through the connecting component unobstructed and irradiate the palm recognition area, it can ensure that the area is illuminated evenly and brightly. This helps to improve the quality of image acquisition and the recognition accuracy. The transparency of the connecting component helps to reduce shadows and light spots caused by the component itself or the gap between it and the palm. These shadows and light spots may interfere with the image acquisition process and reduce the recognition accuracy. Uniform and bright illumination can shorten the image acquisition time and improve the recognition efficiency. This helps to enhance the user experience and reduce dissatisfaction caused by excessive waiting time.
