[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0049] In order to solve the technical problem in the prior art of how to conveniently and quickly unlock a head-mounted device while protecting user privacy, the present application provides a head-mounted device unlocking method, device, electronic device and storage medium, which can conveniently and quickly match and unlock through the distribution information of the blood vessels of the eye, thereby improving the unlocking speed and convenience of the head-mounted device while protecting user privacy, and enhancing the user experience.

[0050] The first embodiment of the present application provides a method for unlocking a head mounted device. The method can be applied to Figure 1 The system architecture shown in the figure includes at least a data acquisition module 101 and a data processing module 102, and the data acquisition module 101 and the data processing module 102 establish a communication connection. Specifically, the system architecture can be a head-mounted device, such as VR glasses or AR glasses, etc., without limitation.

[0051] Next, based on the system architecture, the unlocking method of the head mounted device is described in detail, such as Figure 2 , the head mounted device unlocking method includes:

[0052] Step 201: Obtain eye blood vessel distribution information of a target object wearing a head mounted device.

[0053] The target object may be a user wearing a head mounted device. Taking the head mounted device as VR glasses as an example, an infrared camera (also referred to as an infrared camera) may be set at a position close to the human eye of the VR glasses. The infrared camera may capture the user's eyeball image and obtain the eyeball vascular distribution information based on the eyeball image. Specifically, two infrared cameras A and B may be set, with camera A capturing the user's left eyeball image and camera B capturing the user's right eyeball image. The left eyeball vascular distribution information is then obtained from the left eyeball image, and the right eyeball vascular distribution information is obtained from the right eyeball image. It should be noted that the infrared camera may also be other devices that can collect human eye vascular information, and the embodiments of the present application do not limit the device for obtaining the eyeball vascular distribution information.

[0054] In one embodiment, obtaining eye vascular distribution information of a target object wearing a head mounted device includes: obtaining choroidal vascular distribution information of the target object when it is determined that the target object wears the head mounted device; and using the choroidal vascular distribution information as the eye vascular distribution information.

[0055] The human eye has a multi-layer structure, including the iris, choroid, sclera, and retina. The iris has few textures, many surface pigments, and strong instability due to light, which makes it difficult to read iris features in black eyes. In addition, it is difficult to miniaturize the image acquisition equipment for iris recognition. Iris recognition needs to process a large amount of data, and the requirements for software and hardware are relatively high, resulting in high costs and not suitable for VR glasses. The choroid is located between the sclera and the retina. The choroid contains a large number of blood vessels, and its blood supply accounts for almost 90% of the total blood flow of the eye. In this embodiment, when it is determined that the target object is wearing a head-mounted device, the choroidal vascular distribution information of the target object is obtained, and the choroidal vascular distribution information is used as the eyeball vascular distribution information. Since the shape distribution of each person's eyeball vascular image is different and has individual differences, the choroidal vascular distribution information can be used as a feature of biometric identification to improve the security of unlocking and identification.

[0056] In one embodiment, determining whether the target object is wearing a head mounted device includes: detecting a wearing signal through a wearing sensor configured on the head mounted device; and determining that the target object is wearing the head mounted device when the wearing signal indicates that the head mounted device is worn by the target object.

[0057] In this embodiment, the head-mounted device may be configured with a wearing sensor for detecting whether it is worn. The wearing sensor may identify whether the head-mounted device is worn and output a corresponding wearing signal when the target object wears the head-mounted device. The head-mounted device may collect the eye blood vessel distribution information of the target object according to the wearing signal. For example, when the wearing sensor detects that the target object is wearing the head-mounted device, the infrared camera is awakened by the wearing signal, and the infrared camera collects the eye blood vessel distribution information of the target object. When the target object cannot be detected, the infrared camera may be in a dormant state, thereby reducing energy consumption and unnecessary image acquisition data.

[0058] In one embodiment, obtaining the choroidal vascular distribution information of the target object includes: emitting near-infrared light through an infrared camera of a head-mounted device to obtain an eye image of the target object; extracting vascular information from the eye image using a feature extraction algorithm; and classifying the vascular information based on a machine learning algorithm to obtain the choroidal vascular distribution information.

[0059] In this embodiment, the imaging of choroidal blood vessels can utilize imaging technology in the near-infrared spectral region, because near-infrared light can better penetrate the sclera and retina, ensuring that the near-infrared light reaches the choroid and is absorbed by the blood in the choroidal blood vessels. After the infrared camera emits near-infrared light, the eyeball image of the target object can be obtained, and the vascular information in the eyeball image can be extracted using a feature extraction algorithm. The vascular information can include edges, textures, shapes, and patterns, and then the vascular information is classified based on a machine learning algorithm to obtain choroidal blood vessel distribution information. Of course, before feature extraction, the eyeball image can be preprocessed, such as denoising and adjusting the contrast. Denoising can use a filter to remove artifacts in the eyeball image, and adjusting the contrast can enhance the contrast of the eyeball image, making the features in the eyeball image more obvious, which is convenient for feature extraction.

[0060] In one embodiment, near-infrared light is emitted by an infrared camera of a head-mounted device to acquire an eye image of a target object, including: emitting near-infrared light in a target wavelength range to the target object through the infrared camera of the head-mounted device; wherein the near-infrared light in the target wavelength range is used to penetrate into the choroid of the target object and is absorbed by blood in the blood vessels of the choroid; and acquiring the eye image of the target object while the infrared camera emits near-infrared light and continues to emit it for a preset period of time.

[0061] In this embodiment, in order to ensure that the eye image of the target object is obtained more clearly and accurately, the infrared camera of the head-mounted device can emit near-infrared light in the target wavelength range to the target object. The near-infrared light in the target wavelength range can penetrate the choroid of the target object and be absorbed by the blood in the blood vessels of the choroid. When the infrared camera emits near-infrared light and continues to emit it for a preset time, the eye image of the target object can be obtained. The preset time can be set as needed, taking into account the reaction sensitivity of unlocking and ensuring the clarity of the eye image, and no specific restrictions are made.

[0062] Step 202, matching the eyeball blood vessel distribution information with a preset unlocking key to obtain a matching result; wherein the preset unlocking key includes pre-stored target blood vessel distribution information.

[0063] In one embodiment, before matching the eyeball vascular distribution information with a preset unlocking key to obtain a matching result, the method includes: determining that the head-mounted device enters a key configuration mode; in the key configuration mode, obtaining target vascular distribution information of a first object wearing the head-mounted device; and determining a preset unlocking key based on the target vascular distribution information.

[0064] In this embodiment, the preset unlocking key can be configured by the user. First, the head-mounted device enters the key configuration mode. For example, the process in which the owner of the head-mounted device collects the eye vascular distribution information for the first time can be considered as the key configuration mode of the head-mounted device. There is no limit on the number of first objects. The target vascular distribution information of one user can be collected, or the target vascular distribution information of multiple users can be collected. All the collected target vascular distribution information is stored in the head-mounted device as the preset unlocking key for unlocking the head-mounted device later.

[0065] In one embodiment, the eyeball vascular distribution information is matched with a preset unlocking key to obtain a matching result, including: matching the eyeball vascular distribution information with the target vascular distribution information in the preset unlocking key to obtain a matching similarity; if the matching similarity is greater than or equal to a preset threshold, determining the matching result as a successful match; if the matching similarity is less than the preset threshold, determining the matching result as a failed match.

[0066] In this embodiment, when the user wears the head-mounted device for use, the head-mounted device will perform similarity matching on the currently collected eye vascular distribution information of the user with the target vascular distribution information in the preset unlocking key, and obtain the matching similarity with each target vascular distribution information. When any matching similarity is greater than or equal to a preset threshold, it can be determined that the eye vascular distribution information and the target vascular distribution information corresponding to the matching similarity are successfully matched, and the head-mounted device can be unlocked for use by the user. If each matching similarity is less than the preset threshold, the matching fails, and the head-mounted device can send a prompt message indicating the matching failure. The prompt message can be a voice prompt message or an indicator light prompt, without limitation.

[0067] Step 203: When the matching result indicates that the matching is successful, unlock the head mounted device.

[0068] The method obtains the eye vascular distribution information of the target object wearing the head-mounted device, and matches it with the target vascular distribution information in a pre-stored unlocking key. If the match is successful, the head-mounted device is unlocked. This improves the unlocking speed and convenience of the head-mounted device while protecting the user's privacy, thereby enhancing the user experience.

[0069] In a specific embodiment, taking the head mounted device as a VR device as an example, the head mounted device unlocking method is as follows: Figure 3 ,include:

[0070] The VR device detects that it is being worn;

[0071] The infrared camera captures the wearer’s eye image information;

[0072] The device extracts the eyeball image to obtain the blood vessel distribution image;

[0073] Determine whether the eyeball blood vessel image matches the stored secret key;

[0074] If they match, the device is unlocked successfully; if they do not match, the unlocking fails.

[0075] In this embodiment, the head mounted device may include the following modules:

[0076] 1. Wearing detection module: Place a sensor on the VR device. When the user wears the device, the device will detect that it is being worn, thereby triggering the infrared information acquisition module to start collecting human eye images.

[0077] 2. Information collection module: Two infrared cameras are placed on the VR device near the human eye. When the module is triggered, it starts to automatically collect images of the human eye.

[0078] 3. Image processing module: After the camera collects human eye information, this module extracts features from the image to obtain information on the distribution of blood vessels in the eye.

[0079] 4. Key storage module: After the device owner collects the blood vessel distribution information of the human eye for the first time, the information will be stored in the key storage module and used as the matching key for the next unlocking.

[0080] 5. Secret key matching module: After collecting the wearer's eye vascular distribution information, it will be matched with the secret key stored in the system. When the matching similarity is greater than the set threshold, it is judged to be a successful match and the VR device can be unlocked.

[0081] In this embodiment, since the shape distribution of each person's eyeball blood vessel image is different and has individual differences, the eyeball blood vessel information is used as a feature for biometric identification. In addition, since the absorption rate of hemoglobin to infrared light is different from that of other tissues, the infrared light of the infrared camera emits infrared light to the human eye, and then forms an image on the image sensor, so that the infrared image information of the human eye can be obtained, and the infrared image information is processed and extracted to obtain the eyeball blood vessel distribution information. Therefore, the eyeball blood vessel distribution information is matched with the secret key stored in the system, and the VR device is determined to be unlocked according to the matching result. Compared with the unlocking method of using a handle or gesture recognition to click the virtual keyboard and the unlocking method of fingerprint recognition, the unlocking method of this embodiment can unlock the VR device conveniently and quickly, improve the speed of unlocking the device, and enhance the user experience.

[0085] The unlocking module 403 is configured to unlock the head mounted device if the matching result indicates a successful match.

[0086] The device obtains the eye vascular distribution information of the target object wearing the head-mounted device, and matches it with the target vascular distribution information in a pre-stored unlocking key. If the match is successful, the head-mounted device is unlocked. This improves the unlocking speed and convenience of the head-mounted device while protecting the user's privacy, thereby enhancing the user experience.
