[0002] Vein recognition systems mainly include palm vein recognition system, finger vein recognition system, foot vein recognition system, facial vein recognition system, back of hand vein recognition system, etc. A complete vein recognition system includes a lens, DSP processor, SOC processor, memory, communication interface and security chip.

[0003] When vein recognition is applied to scenes such as supermarkets and subway gates, the vein sensing area is usually set separately and the sensing area is small, which makes it easy for users to accurately move the body parts used for vein recognition, such as palms, in front of the camera to collect vein information. However, setting up the vein sensing area separately limits the development and application of vein recognition technology. When vein recognition technology is applied to fields such as automobiles, the vein sensing area needs to be integrated with other parts of the vehicle (for example, the B-pillar). It may be inconvenient for users to accurately find the vein sensing area when using it, resulting in a decrease in the application frequency and recognition accuracy of the vein recognition system.

[0031] Figure 2 The figure is a schematic diagram of installing the vein recognition detection device according to an embodiment of the utility model on the B-pillar of a vehicle. DETAILED DESCRIPTION

[0032] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0033] In order to thoroughly understand the present invention, a detailed description will be provided in the following description to illustrate the vein recognition detection device, B-pillar exterior panel assembly and vehicle of the present invention. Obviously, the implementation of the present invention is not limited to the specific details familiar to technicians in the field of vein recognition technology. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0034] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of the features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0035] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions is exaggerated, and the same reference numerals are used to represent the same elements, and thus their description will be omitted.

[0036] In the prior art, the sensing area of ​​some vein recognition devices is not obvious, especially when the vein sensing area is not set separately, for example, when it is integrated with the B-pillar of the vehicle, the B-pillar itself needs to maintain its smooth surface, and the vehicle as a whole also needs to maintain its beautiful appearance, which makes it difficult for users to accurately find the vein sensing area on the entire surface of the B-pillar. Users may therefore give up using the vein recognition function, or users may move their palms back and forth in the B-pillar area to try to find the vein sensing area, but this is not conducive to collecting clear vein information, resulting in a lower success rate of vein recognition and a poor user experience.

[0037] In view of the above problems, the utility model provides a vein recognition detection device, such as Figure 1 As shown, including:

[0038] An information collection device 110, used to obtain vein information;

[0039] The indicating device 120 is used to indicate the position of the information collecting device 110 .

[0040] In one embodiment, the vein recognition detection device only needs to collect images in the air, without the user's hand touching the device, which is more hygienic and easier to operate. Vein recognition detection equipment includes but is not limited to detection equipment for palm vein recognition, back of hand vein recognition, facial vein recognition, etc. Taking the palm vein recognition detection device as an example, it usually uses near-infrared light to illuminate the palm, and the sensor senses the light reflected by the palm. Since the hemoglobin in the red blood cells flowing into the veins absorbs near-infrared light near a wavelength of 760nm, the reflection of the vein part is less, and a vein pattern will be generated on the image. The read vein data is then compared with the pre-stored palm vein data to identify the user.

[0041] In one embodiment, the information collection device 110 uses a near-infrared camera to generate a vein pattern by utilizing the absorption property of hemoglobin in venous red blood cells to near-infrared rays with a wavelength of 760 nm. However, this is not restrictive, and the information collection device 110 can also use a monochrome imaging camera, a color imaging camera, an infrared camera, a wide-angle camera, a stereo camera, or a combination thereof to obtain vein information, and cooperate with a corresponding processor to generate a vein image.

[0042] In one embodiment, the vein recognition detection device further includes a processor (not shown), which is connected to the information acquisition device 110, and is used to obtain vein information and generate a vein image based on the vein information, and compare the generated vein image with the pre-stored palm vein data of the user, and the processor can be further used to determine whether to open the door according to the comparison result. The processor can be implemented as software, hardware, firmware or any combination thereof, and can use a single or multiple application specific integrated circuits (ASIC), a single or multiple general integrated circuits, a single or multiple microprocessors, a single or multiple programmable logic devices, or any combination of the aforementioned circuits and / or devices, or other suitable circuits or devices.

[0043] In one embodiment, the vein recognition detection device further includes a memory (not shown), which is connected to the processor and is used to store the user's palm vein data. The user's palm vein data can be continuously updated as the unlocking is successful to improve the success rate of vein recognition. The memory can be a flash memory card, a solid-state memory, a hard disk, etc., which can be a volatile memory and / or a non-volatile memory, a removable memory and / or a non-removable memory, etc.

[0044] In one embodiment, Figure 1 As shown, the indicating device 120 includes an indicator light. The indicating device 120 can be a single indicator light or a combination of multiple indicator lights, which is not limited here.

[0045] In one embodiment, when the indicator device 120 is a single indicator light, it may be in the shape of an arrow, with the tip of the arrow pointing to the information collection device 110. For example, the indicator device 120 is disposed directly above the information collection device 110, the indicator device 120 is an arrow pointing downward, and the distance between the tip of the arrow and the information collection device 110 is 2 cm to 5 cm.

[0046] Exemplarily, the indicating device 120 is disposed around the information collecting device 110 .

[0047] In one embodiment, when the indicating device 120 is a single indicator light, a single light bar or light belt can be designed to surround the information collection device 110, for example, the single indicator light is designed to be a ring shape, and the information collection device 110 is placed at the center of the ring. The area surrounded by the ring is the venous sensing area, and the radius of the venous sensing area is usually 2cm to 5cm. In addition, the indicator light can also be designed to be a triangle, square, rectangle, five-pointed star or other shapes, which are not limited here.

[0048] In one embodiment, when the indicator device 120 is a combination of multiple indicator lights, the indicator device 120 can not only combine the multiple indicator lights into multiple shapes, but also make the indicator lights have different colors. Figure 1 In the embodiment shown, the indicator device 120 includes 30 RGB tri-color LED lamp beads arranged radially from the center to the periphery, and the color of each lamp bead can be different. The indicator device 120 can also include multiple layers of indicator lights, for example, a circular indicator light is set at 3 cm, 4 cm and 5 cm away from the information collection device.

[0049] Exemplarily, the indicating device 120 includes a plurality of lighting modes, and different lighting modes are used to indicate different working states.

[0050] In one embodiment, when the indicator device 120 is a single indicator light, the indicator device 120 can be in a constant light mode or a flashing mode. When the indicator device 120 is a plurality of indicator lights, the indicator device 120 can also present a colorful mode, a flowing water mode, a dot matrix mode, etc.

[0051] In one embodiment, the indicator device 120 is in communication connection with the processor. The mode of the indicator device 120 is different when the door is to be unlocked and when the door is successfully unlocked. For example, when the door is to be unlocked, the indicator device 120 is in a constant light mode; when the door is successfully unlocked, the indicator device 120 flashes several times and then goes out. Alternatively, when the door is to be unlocked, the three-layer indicator light of the indicator device 120 flashes from the outside to the inside, and the venous sensing area indicated by it gradually decreases; when the door is successfully unlocked, the three-layer indicator light of the indicator device flashes from the inside to the outside or the three-layer indicator light is lit at the same time or presents a colorful mode to indicate that the door has been successfully unlocked.

[0052] Exemplarily, the vein recognition detection device further includes a radar module 104 .

When no person is approaching, the vein recognition detection device is in a low power consumption mode, at which time the information collection device 110 and the indication device 120 are not working, so the indicator light is off. When the radar module 104 detects a signal of a person approaching, the vein recognition detection device is awakened and switched from a low power consumption mode to an identification mode (i.e., the door is to be unlocked). When entering the identification mode (i.e., the door is to be unlocked), the information collection device 110 and the indication device 120 both enter the working state, the indicator light is on to indicate the vein sensing area, and the information collection device 110 is used to collect vein information.
