Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0027] Please also read Figures 1 to 4 Now, the head mounted display device 100 based on palm recognition payment provided by the embodiment of the present application is described. The head mounted display device 100 based on palm recognition payment includes:

[0028] The housing 10 is provided with a mounting cavity;

[0029] A light guide cover 20 is provided on the front side of the housing 10;

[0030] A VR display module 30 is disposed in the installation cavity of the housing 10;

[0031] The palm recognition module 40 is arranged in the installation cavity of the housing 10 and close to the inner side of the light guide mask 20, and includes a control board 41, an infrared fill light 42, an infrared image sensor (not shown) and a first lens 43. The control board 41 is connected to the infrared fill light 42 and the infrared image sensor respectively. The infrared fill light 42 and the infrared image sensor are arranged in parallel. The first lens 43 is arranged on the infrared image sensor.

[0032] The main control board 50 is disposed in the installation cavity of the housing 10 and is connected to the VR display module 30 and the palm recognition module 40 respectively.

[0033] It can be understood that the shell 10 protects the entire device, and the installation cavity is used to accommodate the VR display module 30, the palm recognition module 40 and the main control board 50.

[0034] When the user watches VR virtual reality or metaverse through the VR display module 30, such as purchasing weapons and equipment in the game, or paying for the purchase of virtual goods in the metaverse, in conjunction with the financial payment process, the main control board 50 sends a palm vein recognition verification command to the control board 41, and the control board 41 simultaneously turns on the infrared fill light 42 and the infrared image sensor. The user only needs to place the palm 5cm to 10cm in front of the light guide mask 20, and the infrared light will irradiate the palm. A part of the infrared light will be reflected to the infrared image sensor, and the other part of the infrared light will be absorbed by the human vein. In this way, the infrared image sensor can obtain the palm vein image information and realize vein imaging. After the vein recognition authentication is passed, the payment procedure is executed.

[0035] In this way, users can complete identity authentication and payment procedures without taking off VR or other head-mounted display devices, which improves convenience.

[0036] Compared with the prior art, the head-mounted display device 100 based on palm recognition payment provided in the present application, by setting the palm recognition module 40 in the installation cavity of the shell 10, the infrared fill light 42 can perform infrared fill light through the light guide mask 20, and the infrared image sensor obtains the vein image information of the palm. After the vein recognition authentication is passed, the user can realize identity authentication and payment procedures without taking off the VR and other head-mounted display devices, thereby improving security and convenience.

[0037] In another embodiment of the present application, please refer to Figure 3 and Figure 4The head-mounted display device 100 based on palm recognition payment also includes a white light fill light 60, a visible light image sensor (not shown) and a second lens 70. The white light fill light 60 and the visible light image sensor are arranged in parallel, and the second lens 70 is arranged on the visible light image sensor. The white light fill light 60 and the visible light image sensor are respectively connected to the main control board 50.

[0038] It can be understood that when performing palm payment, the white light fill light 60 can supplement visible light for the palm to adapt to low-light environments such as at night, and the position of the palm is obtained by the visible light sensor and the second lens 70. The visible light image of the palm can be displayed by the VR display module 30 after it is transmitted to the main control board 50. Therefore, when the user performs vein payment, the position and distance of the palm can be adjusted in real time according to the visible light image of the palm, so that the palm recognition module 40 can collect high-quality vein features and improve the efficiency of palm vein recognition and authentication.

[0039] For further information, please also refer to Figure 2 An oblong hole 21 is provided on the light guide mask 20 , and the infrared fill light 42 , the first lens 43 , the second lens 70 and the white light fill light 60 are located in the oblong hole 21 .

[0040] It can be understood that since the light guide mask 20 is usually set as a curved surface, by setting the infrared fill light 42, the first lens 43, the second lens 70 and the white light fill light 60 in the oblong hole 21, the reflection and distortion problems caused by the light guide mask 20 can be avoided and the image quality can be improved.

[0041] For further information, please also refer to Figure 3 The infrared fill light 42, the infrared image sensor, the visible light image sensor, and the white light fill light 60 are arranged in parallel in sequence.

[0042] It can be understood that, based on the above-mentioned distribution setting, the infrared image sensor and the visible light image sensor can synchronously acquire images of the same relative position and different levels, keeping the relative position of the palm in the two levels of images the same; on the other hand, the infrared fill light 42 and the white light fill light 60 are set far away from each other, which can reduce mutual interference to the image sensor and improve image quality.

[0043] Furthermore, a 650nm filter is arranged between the visible light image sensor and the second lens 70 .

[0044] It can be understood that the 650nm filter is a filter that cuts off the band greater than 650nm and passes the band less than 650nm. It is used for visible light image sensors to filter out infrared light, which can improve the quality of visible light imaging, such as avoiding redness in the image.

[0045] In another embodiment of the present application, the infrared fill light 42 is a near-infrared LED lamp.

[0046] It can be understood that the near-infrared LED lamp can be a dual-crystal infrared LED lamp of 850nm and 940nm, which can emit near-infrared light of different wavelengths to adapt to the vein characteristics of different physiques and improve adaptability.

[0047] In another embodiment of the present application, a first polarizer (not shown) is arranged on the infrared fill light 42, and a second polarizer (not shown) is arranged between the infrared image sensor and the first lens 43, and the polarization directions of the first polarizer and the second polarizer are at an angle of 60 to 90 degrees.

[0048] It can be understood that, since the polarization directions of the first polarizer and the second polarizer are at an angle of 60 to 90 degrees, and the infrared light emitted by the infrared fill light 42 needs to pass through the first polarizer and the second polarizer in sequence before imaging, the characteristics of polarized light are used to eliminate the reflection of the non-palm vein area on the skin surface, thereby filtering out the skin texture information, retaining only the vein information, improving the contrast between the vein area and the non-vein area, and obtaining a clear and non-reflective vein image. Preferably, the polarization directions of the first polarizer and the second polarizer are at an angle of 80 degrees.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
