具体实施方式detailed description
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments.
本实施例提供了一种基于掌纹的解锁方法，图1是根据本发明实施例的基于掌纹的解锁方法的流程图，如图1所示，该方法的步骤包括：This embodiment provides a palmprint-based unlocking method. FIG. 1 is a flowchart of a palmprint-based unlocking method according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps:
步骤S102：在终端为解锁界面时，通过终端的图像采集器获取操作用户手掌的掌纹信息；Step S102: When the terminal is the unlocking interface, obtain the palmprint information of the palm of the user by using the image collector of the terminal;
步骤S104：比较操作用户手掌的掌纹信息与终端本地预先存储的掌纹信息；Step S104: Comparing the palm print information of the user's palm with the palm print information pre-stored locally by the terminal;
步骤S106：在操作用户手掌的掌纹信息与预先存储的掌纹信息的相似度大于第一预定阈值时，触发终端执行解锁操作。Step S106: When the similarity between the palm print information of the palm of the user and the pre-stored palm print information is greater than the first predetermined threshold, the triggering terminal performs the unlocking operation.
通过本发明实施例的上述步骤S102至S106，采用在操作用户需要对终端进行解锁时，在终端为解锁界面时，通过终端的图像采集器获取到该操作用户手掌的掌纹信息；进而比较该掌纹信息与终端本地预先存储的掌纹信息，在两者的相似度大于第一预定阈值时，触发该终端执行解锁操作；由于掌纹的唯一性以及掌纹更易获取与识别，解决了相关技术中终端的解锁方法安全性不高以及识别率不高的问题，达到了提高用户体验的效果。Through the above steps S102 to S106 of the embodiment of the present invention, when the operation user needs to unlock the terminal, when the terminal is the unlock interface, the palmprint information of the palm of the operation user is acquired by the image collector of the terminal; The palmprint information and the pre-stored palmprint information of the terminal locally trigger the terminal to perform an unlocking operation when the similarity between the two is greater than the first predetermined threshold; the palmprint is uniquely located and the palmprint is more easily acquired and recognized, and the correlation is solved. In the technology, the unlocking method of the terminal is not high in security and the recognition rate is not high, and the effect of improving the user experience is achieved.
需要说明的是，在本实施例中该第一预定阈值用户可以根据实际情况进行预定义或者是选择终端自身的缺省设置，例如是80％，此外操作用户手掌的掌纹信息为临时的掌纹信息，也就是说操作用户手掌的掌纹信息是当前用户用来进行解锁的掌纹信息。It should be noted that, in this embodiment, the first predetermined threshold value may be predefined according to an actual situation or a default setting of the terminal itself, for example, 80%, and the palm print information of the user's palm is temporarily held. The pattern information, that is, the palm print information of the user's palm is the palm print information that the current user uses to unlock.
在本实施例的一个可选实施方式中，还可以获取操作用户手掌所处的位置信息，是因为在进行掌纹信息比较时，临时获取的操作用户的手掌与终端本地存储的手掌的位置信息大多数情况下都是不一致，因此需要在获取掌纹信息的同时还获取该手掌的位置信息，进而在进行掌纹信息比较时，先调整临时获取的操作用户的手掌的位置信息与本地存储的手掌的位置信息相匹配，再进行掌纹信息的比较。In an optional implementation manner of this embodiment, the location information of the user's palm is also obtained, because the palm of the user who is temporarily acquired and the location information of the palm stored locally by the terminal are temporarily acquired when the palmprint information is compared. In most cases, it is inconsistent. Therefore, it is necessary to obtain the position information of the palm while acquiring the palm print information, and then adjust the position information of the temporarily acquired operation user's palm and the locally stored when the palm print information is compared. The position information of the palms is matched, and then the palmprint information is compared.
即在本可选实施例中，还可以包括如下步骤：That is, in this optional embodiment, the following steps may also be included:
步骤S11：获取操作用户手掌所处的位置信息； Step S11: acquiring location information of the user's palm;
步骤S12：调整操作用户手掌所处的位置信息与终端本地预先存储的手掌的位置信息相匹配。Step S12: The position information of the palm of the user is adjusted to match the position information of the palm stored in advance by the terminal.
对于本实施例涉及到的位置信息可以包括：用户手掌与水平面的第一角度、用户手掌相对于终端向左或向右的旋转第二角度以及用户手掌与终端的距离。The location information related to the embodiment may include: a first angle of the user's palm and the horizontal plane, a second angle of rotation of the user's palm relative to the terminal to the left or the right, and a distance between the user's palm and the terminal.
而对于本实施例中涉及到的掌纹信息可以包括：用户手掌的大小、操作用户手掌的纹数、操作用户手掌纹路的走向、长短、形状以及交叉点。The palmprint information involved in this embodiment may include: the size of the user's palm, the number of lines of the palm of the user, the direction of the palm of the user's palm, the length, the shape, and the intersection.
而在本实施例的另一个可选实施方式中，通过终端的图像采集器获取操作用户手掌的掌纹信息之前，该方法还可以包括：In another optional implementation manner of the embodiment, before acquiring the palmprint information of the palm of the user by the image collector of the terminal, the method may further include:
步骤S21：获取用于存储在终端本地的用户手掌的掌纹信息以及用户手掌所处的位置信息，；Step S21: acquiring palmprint information for storing the palm of the user local to the terminal and location information of the palm of the user;
步骤S22：在用于存储在终端本地的用户手掌的掌纹信息与图像采集器的取景界面信息比较大于第二预定阈值时，存储用于存储在终端本地的用户手掌的掌纹信息。Step S22: When the palm print information for storing the palm of the user local to the terminal is compared with the view interface information of the image collector by more than a second predetermined threshold, the palm print information for storing the palm of the user local to the terminal is stored.
通过步骤S21和步骤S22可知，存储在终端本地掌纹信息，在获取的过程中该掌纹信息需要大于图像采集器的取景界面信息比较大于第二预定阈值，这样才能存储该掌纹信息，如果该掌纹信息与图像采集器的取景界面信息比较小于第二预定阈值，则获取掌纹信息失败，该掌纹信息不能存储在终端本地，重新获取掌纹信息，直到满足上述条件。The step S21 and the step S22 can be used to store the palmprint information in the terminal. In the process of acquiring, the palmprint information needs to be greater than the second predetermined threshold of the image capturing device, so that the palmprint information can be stored. If the palmprint information is compared with the framing interface information of the image collector by less than the second predetermined threshold, the palmprint information is failed, and the palmprint information cannot be stored locally in the terminal, and the palmprint information is re-acquired until the above condition is met.
