本发明涉及移动终端操控技术领域，尤其涉及一种移动终端屏幕的解锁方法及移动终端。The present invention relates to the technical field of mobile terminal manipulation, in particular to a mobile terminal screen unlocking method and a mobile terminal.
背景技术Background technique
现在手机成为用户越来越重要的电子消费产品，很多扩展功能也在手机上应用，特别是涉及到用户财产(例如支付宝、微信)、隐私(例如相册、微信、QQ)，手机的保密性越来越重要，因而手机的解锁方式(例如快速的指纹解锁)也越来越成为手机厂商的卖点。其中，当前市面手机的解锁方式大致分为：Now mobile phones have become more and more important electronic consumer products for users, and many extended functions are also applied on mobile phones, especially when it comes to user property (such as Alipay, WeChat) and privacy (such as photo albums, WeChat, QQ), the confidentiality of mobile phones is getting higher and higher. Therefore, the unlocking method of mobile phones (such as fast fingerprint unlocking) has become more and more a selling point of mobile phone manufacturers. Among them, the current unlocking methods of mobile phones on the market are roughly divided into:
1、用手机界面密码来解锁，其中包括手机输入数字解锁，以及画九格图案解锁；1. Use the password on the mobile phone interface to unlock, including entering a number on the mobile phone to unlock, and drawing a nine-grid pattern to unlock;
2、使用指纹识别传感器进行指纹解锁，其中包括放置于手机前面的指纹传感器实现前置指纹解锁，以及放置于手机后面的指纹传感器实现后置指纹解锁。2. Use the fingerprint recognition sensor for fingerprint unlocking, including the fingerprint sensor placed on the front of the mobile phone to realize the front fingerprint unlocking, and the fingerprint sensor placed on the back of the mobile phone to realize the rear fingerprint unlocking.
其中，使用屏幕密码解锁或者在手机屏幕上画图案解锁的解锁方式，由于在解锁过程中容易被他人看到，或者在手机上划过的图案由于手指带有汗液，容易形成划痕，从而被其他人破解。另外，在用户使用该方式解锁时，用户解锁的操作过程也比较复杂，特别是单手操作的时候，很不方便，用户体验也差。Among them, using the screen password to unlock or drawing a pattern on the screen of the mobile phone is easy to be seen by others during the unlocking process, or the pattern drawn on the mobile phone is easy to form scratches due to sweat on the fingers, so it is blocked. Others crack. In addition, when the user uses this unlocking method, the user's unlocking operation process is relatively complicated, especially when the user operates with one hand, it is very inconvenient and the user experience is also poor.
另外，虽然使用指纹识别解锁现在越来越成为手机厂商的潮流，具有操作简单，解锁速度快的优点，但是指纹识别由于是硬件传感器，肯定存在单体不良的失效情况，可能出现不能解锁、不是特定指纹也可以解锁的情况，而且在解锁时，如果手指有脏污或者水渍的时候，通常是无法进行指纹解锁的。因此，指纹识别解锁对用户的保密情况存在不确定性。此外，在手机的设计制作过程中，指纹识别模组的增加也大大增加了硬件成本和设计难度，降低了整机的可靠性。In addition, although using fingerprint recognition to unlock is becoming more and more a trend of mobile phone manufacturers, it has the advantages of simple operation and fast unlocking speed, but because the fingerprint recognition is a hardware sensor, there must be a failure of a single unit, and it may not be unlocked, not Specific fingerprints can also be unlocked, and when unlocking, if the fingers are dirty or water-stained, it is usually impossible to unlock the fingerprint. Therefore, there is uncertainty in the confidentiality of the user for fingerprint recognition and unlocking. In addition, in the design and production process of the mobile phone, the increase of the fingerprint recognition module also greatly increases the hardware cost and design difficulty, and reduces the reliability of the whole machine.
由上述可知，现有的手机解锁方式无法在保证用户操作便利性的同时降低设计成本，并增强保密性。From the above, it can be seen that the existing mobile phone unlocking methods cannot reduce the design cost and enhance the confidentiality while ensuring the convenience of the user's operation.

具体实施方式detailed description
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
第一实施例first embodiment
如图1所示，为本发明第一实施例的移动终端屏幕的解锁方法的流程图，该方法包括：As shown in Figure 1, it is a flow chart of the unlocking method of the mobile terminal screen of the first embodiment of the present invention, the method includes:
步骤101：在移动终端屏幕锁屏状态下，获取解锁移动终端屏幕的指令。Step 101: Obtain an instruction to unlock the screen of the mobile terminal when the screen of the mobile terminal is locked.
本发明的实施例应用于手机、平板电脑等设置有摄像头的移动终端，且在该类移动终端中预先建立有解锁图像库。其中，可通过进入移动终端的设置页面，设置解锁图像。即，进入移动终端的设置页面后，利用移动终端的摄像头对拍摄对象进行拍摄，并将拍摄的图像存储在解锁图像库中，以便于在利用摄像头进行屏幕解锁时使用。The embodiments of the present invention are applied to mobile terminals equipped with cameras, such as mobile phones and tablet computers, and an unlocking image library is pre-established in such mobile terminals. Wherein, the unlocking image can be set by entering the setting page of the mobile terminal. That is, after entering the setting page of the mobile terminal, the camera of the mobile terminal is used to take pictures of the subject, and the captured images are stored in an unlocked image library for use when the camera is used to unlock the screen.
其中，在本发明的实施例中，所述解锁图像包括多种拍摄对象的图像。即用户可通过摄像头拍摄多种不同的拍摄对象的图像作为解锁图像。例如拍摄多种物品的图像作为解锁图像，或者拍摄用户身体的不同部位(如脸部、掌纹)，或者拍摄用户自己摆出的特定手势等。Wherein, in the embodiment of the present invention, the unlocking image includes images of various shooting objects. That is, the user may take images of various subjects through the camera as unlocking images. For example, take images of various items as unlocking images, or take pictures of different parts of the user's body (such as face and palm prints), or take pictures of specific gestures made by the user.
因此，本发明实施例的移动终端屏幕的解锁方法不同与现有技术的人脸解锁。其中，现有技术的人脸解锁的解锁图像就是移动终端用户的脸部，从而使得其他人容易利用移动终端用户的人脸照片进行解锁，安全性较低。相比之下，本发明实施例中的解锁图像库中存储的解锁图像灵活多样，且只有用户自己知道，具备较好的安全性。Therefore, the method for unlocking the screen of the mobile terminal in the embodiment of the present invention is different from face unlocking in the prior art. Wherein, the unlocking image of the face unlocking in the prior art is the face of the mobile terminal user, so that other people can easily use the face photo of the mobile terminal user to unlock, and the security is low. In contrast, the unlocking images stored in the unlocking image database in the embodiment of the present invention are flexible and diverse, and only the user himself knows, which has better security.
另外，在移动终端屏幕处于锁屏状态下，用户可按照移动终端自身支持的摄像头快速启动方式，在移动终端上进行相应操作，以使得移动终端生成解锁移动终端屏幕的指令，进而根据该指令启动移动终端的摄像头。In addition, when the screen of the mobile terminal is locked, the user can perform corresponding operations on the mobile terminal according to the camera quick start mode supported by the mobile terminal itself, so that the mobile terminal generates an instruction to unlock the screen of the mobile terminal, and then starts the camera according to the instruction. The camera of the mobile terminal.

步骤103：获取所述摄像头捕捉的至少一个目标图像。Step 103: Obtain at least one target image captured by the camera.
其中，摄像头捕捉的所述目标图像可以是对同一拍摄对象捕捉的多个图像，或者对多个不同拍摄对象分别捕捉的图像，或者对多个拍摄对象位于同一拍摄界面中时捕捉的图像。Wherein, the target image captured by the camera may be multiple images captured for the same subject, or images captured separately for multiple different subjects, or images captured when multiple subjects are located in the same shooting interface.
另外，摄像头启动进入到拍照模式后，在移动终端的显示界面可以实时观看到摄像头所捕捉的目标图像。其中，由于解锁图像库中的解锁图像为多种拍摄对象的图像，所以，用户可以利用多种拍摄对象进行解锁，解锁对象灵活多样。其中，当用户不方便利用其中某个拍摄对象进行解锁时，可以利用其它拍摄对象进行解锁，解锁操作非常灵活。例如，解锁图像库中的解锁图像包括有A、B、C这三个拍摄对象的图像，则当用户不方便利用A来进行解锁时，可利用B或者C来进行解锁。此外，为了进一步增强解锁操作的复杂程度，从而增强保密效果，可利用多个拍摄对象进行解锁。例如，利用A+B组合或B+C组合或A+B+C组合来进行解锁。In addition, after the camera is activated and enters the camera mode, the target image captured by the camera can be viewed in real time on the display interface of the mobile terminal. Wherein, since the unlocking images in the unlocking image database are images of various shooting objects, the user can use various shooting objects for unlocking, and the unlocking objects are flexible and diverse. Among them, when it is inconvenient for the user to use one of the shooting objects to unlock, other shooting objects can be used to unlock, and the unlocking operation is very flexible. For example, the unlocked images in the unlocked image library include images of three subjects A, B, and C, and when it is inconvenient for the user to use A to unlock, B or C can be used to unlock. In addition, in order to further increase the complexity of the unlocking operation, thereby enhancing the security effect, multiple shooting objects can be used for unlocking. For example, A+B combination, B+C combination or A+B+C combination is used for unlocking.
步骤104：当所述至少一个目标图像与预先存储在解锁图像库中的解锁图像相匹配时，执行屏幕解锁操作。Step 104: When the at least one target image matches the unlocking image pre-stored in the unlocking image library, perform a screen unlocking operation.
通过步骤103获取到摄像头捕捉的至少一个目标图像后，可进一步根据预先在解锁图像库中存储的解锁图像，执行屏幕解锁操作。即当所述至少一个目标图像与预先存储在解锁图像库中的解锁图像相匹配时，执行屏幕解锁操作，解锁成功，否则解锁失败。After at least one target image captured by the camera is acquired through step 103, the screen unlocking operation may be further performed according to the unlocking image pre-stored in the unlocking image library. That is, when the at least one target image matches the unlocking image pre-stored in the unlocking image library, the screen unlocking operation is performed, and the unlocking is successful; otherwise, the unlocking fails.
由上述可知，本发明的实施例，能够在移动终端屏幕处于锁屏状态下，获取解锁移动终端屏幕的指令，从而根据该指令启动移动终端的摄像头，使得移动终端的摄像头可以捕捉目标图像，进而当摄像头捕捉的至少一个目标图像与预先在解锁图像库中存储的解锁图像相匹配时，执行屏幕解锁操作。因此，本发明实施例的移动终端屏幕的解锁方法，未增加任何硬件设备，仅利用移动终端现有硬件设备即可实现屏幕解锁，操作简单方便，且解锁图像库中的解锁图像只有用户自己知道，保密性良好，有效解决了现有的解锁方式无法在保证用户操作便利性的同时降低设计成本并增强保密性的技术问题。As can be seen from the above, the embodiments of the present invention can obtain an instruction to unlock the screen of the mobile terminal when the screen of the mobile terminal is in a locked state, thereby starting the camera of the mobile terminal according to the instruction, so that the camera of the mobile terminal can capture the target image, and then When at least one target image captured by the camera matches the unlocking image pre-stored in the unlocking image library, a screen unlocking operation is performed. Therefore, the method for unlocking the screen of a mobile terminal according to the embodiment of the present invention does not add any hardware devices, and only the existing hardware devices of the mobile terminal can be used to unlock the screen. The operation is simple and convenient, and only the user knows the unlocked images in the unlocked image library. , with good confidentiality, which effectively solves the technical problem that the existing unlocking methods cannot reduce the design cost and enhance the confidentiality while ensuring the convenience of user operation.
第二实施例second embodiment
如图2所示，为本发明第二实施例的移动终端屏幕的解锁方法的流程图，该方法包括：As shown in Figure 2, it is a flow chart of the unlocking method of the mobile terminal screen of the second embodiment of the present invention, the method includes:
步骤201：在移动终端屏幕锁屏状态下，获取解锁移动终端屏幕的指令。Step 201: Obtain an instruction to unlock the screen of the mobile terminal when the screen of the mobile terminal is locked.
本发明的实施例应用于手机、平板电脑等设置有摄像头的移动终端，且在该类移动终端中预先建立有解锁图像库。其中，可通过进入移动终端的设置页面，设置解锁图像。即，进入移动终端的设置页面后，利用移动终端的摄像头对拍摄对象进行拍摄，并将拍摄的图像存储在解锁图像库中，以便于在利用摄像头进行屏幕解锁时使用。The embodiments of the present invention are applied to mobile terminals equipped with cameras, such as mobile phones and tablet computers, and an unlocking image library is pre-established in such mobile terminals. Wherein, the unlocking image can be set by entering the setting page of the mobile terminal. That is, after entering the setting page of the mobile terminal, the camera of the mobile terminal is used to take pictures of the subject, and the captured images are stored in an unlocked image library for use when the camera is used to unlock the screen.
其中，在本发明的实施例中，所述解锁图像包括多种拍摄对象的图像。即用户可通过摄像头拍摄多种不同的拍摄对象的图像作为解锁图像。例如拍摄多种物品的图像作为解锁图像，或者拍摄用户身体的不同部位(如脸部、掌纹)，或者拍摄用户自己摆出的特定手势等。Wherein, in the embodiment of the present invention, the unlocking image includes images of various shooting objects. That is, the user may take images of various subjects through the camera as unlocking images. For example, take images of various items as unlocking images, or take pictures of different parts of the user's body (such as face and palm prints), or take pictures of specific gestures made by the user.
因此，本发明实施例的移动终端屏幕的解锁方法不同与现有技术的人脸解锁。其中，现有技术的人脸解锁的解锁图像就是移动终端用户的脸部，从而使得其他人容易利用移动终端用户的人脸照片进行解锁，安全性较低。相比之下，本发明实施例中的解锁图像库中存储的解锁图像灵活多样，且只有用户自己知道，具备较好的安全性。Therefore, the method for unlocking the screen of the mobile terminal in the embodiment of the present invention is different from face unlocking in the prior art. Wherein, the unlocking image of the face unlocking in the prior art is the face of the mobile terminal user, so that other people can easily use the face photo of the mobile terminal user to unlock, and the security is low. In contrast, the unlocking images stored in the unlocking image database in the embodiment of the present invention are flexible and diverse, and only the user himself knows, which has better security.
另外，在移动终端屏幕处于锁屏状态下，用户可按照移动终端自身支持的摄像头快速启动方式，在移动终端上进行相应操作，以使得移动终端生成解锁移动终端屏幕的指令，进而根据该指令启动移动终端的摄像头。In addition, when the screen of the mobile terminal is locked, the user can perform corresponding operations on the mobile terminal according to the camera quick start mode supported by the mobile terminal itself, so that the mobile terminal generates an instruction to unlock the screen of the mobile terminal, and then starts the camera according to the instruction. The camera of the mobile terminal.
其中，在移动终端处于锁屏状态下，可通过按下移动终端的亮屏按键或返回按键预设次数快速启动移动终端的摄像头，或者在移动终端的亮屏界面的预设区域内利用触摸操作快速启动移动终端的摄像头。例如，快速双击开机亮屏按键，直接启动摄像头，其中，连续两次按下开机亮屏按键的时间间隔可以通过用户自行调整；或者，快速双击返回按键，其中，有些移动终端的机型返回按键是实体按键，则用户快速双击就可以很简单地启动摄像头，然而有些机型是电容触摸按键，同样可以通过快速触摸快速启动摄像头，但是当移动终端放置在口袋中时，需要关闭电容触摸返回按键快速启动摄像头的功能，以免造成误操作。Wherein, when the mobile terminal is in the locked screen state, the camera of the mobile terminal can be quickly started by pressing the screen bright button or the return button preset times of the mobile terminal, or the camera of the mobile terminal can be operated by touch in the preset area of the screen bright interface of the mobile terminal Quickly start the camera of the mobile terminal. For example, quickly double-click the power-on and bright-screen button to directly start the camera, wherein the time interval between pressing the power-on and bright-screen button twice in a row can be adjusted by the user; If it is a physical button, the user can quickly start the camera by double-clicking it quickly. However, some models have a capacitive touch button, and the camera can also be quickly started by a quick touch. However, when the mobile terminal is placed in the pocket, the capacitive touch button needs to be turned off. Quickly start the function of the camera to avoid misuse.
步骤202：根据所述指令，启动所述移动终端的摄像头。Step 202: According to the instruction, start the camera of the mobile terminal.
通过步骤201获取到解锁移动终端屏幕的指令后，则可启动该移动终端的摄像头，进入到拍照模式。After the instruction of unlocking the screen of the mobile terminal is obtained through step 201, the camera of the mobile terminal can be started to enter the photographing mode.
步骤203：获取所述摄像头捕捉的至少一个目标图像。Step 203: Obtain at least one target image captured by the camera.
其中，摄像头捕捉的所述目标图像可以是对同一拍摄对象捕捉的多个图像，或者对多个不同拍摄对象分别捕捉的图像，或者对多个拍摄对象位于同一拍摄界面中时捕捉的图像。Wherein, the target image captured by the camera may be multiple images captured for the same subject, or images captured separately for multiple different subjects, or images captured when multiple subjects are located in the same shooting interface.
另外，摄像头启动进入到拍照模式后，在移动终端的显示界面可以实时观看到摄像头所捕捉的目标图像。其中，由于解锁图像库中的解锁图像为多种拍摄对象的图像，所以，用户可以利用多种拍摄对象进行解锁，解锁对象灵活多样。其中，当用户不方便利用其中某个拍摄对象进行解锁时，可以利用其它拍摄对象进行解锁，解锁操作非常灵活。例如，解锁图像库中的解锁图像包括有A、B、C这三个拍摄对象的图像，则当用户不方便利用A来进行解锁时，可利用B或者C来进行解锁。此外，为了进一步增强解锁操作的复杂程度，从而增强保密效果，可利用多个拍摄对象进行解锁。例如，利用A+B组合或B+C组合或A+B+C组合来进行解锁。In addition, after the camera is activated and enters the camera mode, the target image captured by the camera can be viewed in real time on the display interface of the mobile terminal. Wherein, since the unlocking images in the unlocking image database are images of various shooting objects, the user can use various shooting objects for unlocking, and the unlocking objects are flexible and diverse. Among them, when it is inconvenient for the user to use one of the shooting objects to unlock, other shooting objects can be used to unlock, and the unlocking operation is very flexible. For example, the unlocked images in the unlocked image library include images of three subjects A, B, and C, and when it is inconvenient for the user to use A to unlock, B or C can be used to unlock. In addition, in order to further increase the complexity of the unlocking operation, thereby enhancing the security effect, multiple shooting objects can be used for unlocking. For example, A+B combination, B+C combination or A+B+C combination is used for unlocking.
步骤204：依次提取至少一个目标图像中的至少一个拍摄对象。Step 204: sequentially extract at least one shooting object in at least one target image.
其中，由于摄像头捕捉的所述目标图像可以是对同一拍摄对象捕捉的多个图像，或者对多个不同拍摄对象分别捕捉的图像，或者对多个拍摄对象位于同一拍摄界面中时捕捉的图像，所以一个目标图像中可能包括一个拍摄对象或者多个拍摄对象。Wherein, since the target image captured by the camera may be multiple images captured for the same subject, or images captured separately for multiple different subjects, or images captured when multiple subjects are located in the same shooting interface, Therefore, a target image may include one subject or multiple subjects.
步骤205：将所述至少一个拍摄对象分别与预先在解锁图像库中存储的解锁图像进行比对。Step 205: Compare the at least one photographed object with the unlocking images pre-stored in the unlocking image library.
其中，优选地，步骤205包括：分别计算所述至少一个拍摄对象与所述解锁图像库中的所述解锁图像的相似度；当所述相似度大于第一预设阈值时，所述相似度对应的解锁图像为所述相似度对应的所述拍摄对象的目标解锁图像；存储所述相似度。Wherein, preferably, step 205 includes: respectively calculating the similarity between the at least one subject and the unlocked image in the unlocked image library; when the similarity is greater than a first preset threshold, the similarity The corresponding unlocking image is a target unlocking image of the subject corresponding to the similarity; storing the similarity.
即本发明的实施例采用图像处理技术，将步骤203中获取的目标图像与预先存储的解锁图像进行对比，获得图像对比的相似度。当存在大于第一预设阈值的相似度时，则查找到了与目标图像相匹配的目标解锁图像。其中，第一预设阈值与移动终端的平衡开机速度和识别卡准确度相关。That is, the embodiment of the present invention uses image processing technology to compare the target image obtained in step 203 with the pre-stored unlocking image to obtain the similarity of image comparison. When there is a similarity greater than the first preset threshold, a target unlocking image matching the target image has been found. Wherein, the first preset threshold is related to the balanced startup speed and identification card accuracy of the mobile terminal.
步骤206：当所述解锁图像库中存在与所述拍摄对象相匹配的目标解锁图像时，执行屏幕解锁操作。Step 206: When there is a target unlock image matching the subject in the unlock image library, perform a screen unlock operation.
当通过步骤204将所述至少一个拍摄对象分别与预先在解锁图像库中存储的解锁图像进行比对后，若对比发现所述解锁图像库中存在与拍摄对象相匹配的目标解锁图像，则可执行屏幕解锁操作，成功解锁。否则，若不存在与拍摄对象相匹配的目标解锁图像，则解锁失败，移动终端的显示界面仍然停留在摄像头的拍照界面。另外，还可设置在预设时间段内若未成功解锁，则移动终端进入灭屏待机状态，以节省电量。After step 204, the at least one photographed object is compared with the unlocked images previously stored in the unlocked image database, and if the comparison finds that there is a target unlocked image matching the photographed object in the unlocked image database, you can Execute the screen unlock operation and unlock successfully. Otherwise, if there is no target unlocking image matching the object to be photographed, then the unlocking fails, and the display interface of the mobile terminal remains at the photographing interface of the camera. In addition, it can also be set that if the mobile terminal is not successfully unlocked within a preset time period, the mobile terminal enters a standby state with the screen off, so as to save power.
另外，使用者在录用初始图片的时候，随着使用习惯的变化，摄像头捕捉目标图像的角度也可能发生变化，所以解锁图像的实时更新对解锁极为重要。因此，进一步地，在步骤206之后，还包括：获取已存储的所述相似度；判断所述相似度是否处于预设范围之内；当所述相似度处于所述预设范围之内时，将所述相似度对应的所述目标图像更新至所述解锁图像库。In addition, when the user takes the initial picture, the angle at which the camera captures the target image may also change as the usage habits change, so the real-time update of the unlock image is extremely important for unlocking. Therefore, further, after step 206, it also includes: acquiring the stored similarity; judging whether the similarity is within the preset range; when the similarity is within the preset range, Updating the target image corresponding to the similarity to the unlocking image library.
进一步地，为了使得更新的解锁图像的精确度更好，从而更加快速地利用摄像头进行屏幕解锁，在上述判断所述相似度是否处于预设范围之内的步骤之后，所述方法还包括：当所述相似度处于所述预设范围之内时，获取所述相似度处于所述预设范围之内的次数；当所述相似度处于所述预设范围之内的次数大于第二预设阈值时，将处于所述预设范围之内的所述相似度对应的所述目标图像更新至所述解锁图像库。Further, in order to improve the accuracy of the updated unlocking image, so that the camera can be used to unlock the screen more quickly, after the above step of judging whether the similarity is within a preset range, the method further includes: when When the similarity is within the preset range, obtain the number of times the similarity is within the preset range; when the similarity is within the preset range, the number of times is greater than a second preset When the threshold is reached, the target image corresponding to the similarity within the preset range is updated to the unlocked image library.
举例来说，假设解锁图像库中存储有X1、X2、X3三个解锁图像，且用户曾经n次使用X1进行解锁，且每一次利用X1解锁时计算获得的相似度为Ni(其中，i取值为1～n，n为正整数)。其中，若N1～Nn这n个相似度中，有m(m小于n)个相似度处于预设范围之内，若m达到了第二预设阈值，则可将这m个相似度对应的目标图像添加到解锁图像库中，从而加快解锁速度。For example, assume that there are three unlocking images X1, X2, and X3 stored in the unlocking image database, and the user has used X1 to unlock n times, and the similarity calculated each time using X1 to unlock is Ni (wherein, i is taken as The value is 1~n, n is a positive integer). Among them, if among the n similarities N1 to Nn, there are m (m is less than n) similarities within the preset range, and if m reaches the second preset threshold, then the m similarities corresponding to The target image is added to the unlock image library, which speeds up the unlocking process.
