- the second threshold value can be set according to actual requirements, which is not limited in the embodiment of the present application.
- the terminal does not have a false touch and the process ends; if the light intensity of the environment in which the terminal is located is less than the second threshold, it is determined that the terminal is in the pocket mode.
- the terminal can also detect whether the collected data is fingerprint data. If the collected data is not fingerprint data, it means that the terminal has been touched by mistake.
- the terminal may also detect whether the light intensity of the environment where the terminal is located is less than the second threshold value according to the illumination information; if the light intensity of the environment where the terminal is located is less than the second threshold value, then According to the distance information, detect whether the distance between the terminal and the obstacle is less than the first threshold; if the distance between the terminal and the obstacle is less than the first threshold, then according to the first motion information, detect whether the motion state of the terminal is The first preset condition is met; if the motion state of the terminal meets the first preset condition, it is determined that the terminal is in the pocket mode.

图5为本申请一个实施例提供的终端的框图。
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
相关技术中，终端在解锁成功后还需要用户重新触发快捷图标，该过程较为繁琐，操作效率较低。基于此，本申请实施例提供了一种指纹解锁方法、装置、终端及存储介质。在本申请实施例提供的技术方案中，通过在用户呼出显示负一屏并触发负一屏中的某一快捷图标时，终端通过触摸显示屏下设置的指纹识别模组来采集用户的指纹图像，并在采集到的指纹图像与预存的指纹图像匹配时，对终端进行解锁，并直接显示上述快捷图标的用户界面，相比于相关技术中需要用户先对终端进行解锁，然后重新触发快捷图标，本申请实施例提供的技术方案，在终端显示快捷图标的用户界面所需的操作步骤更少，有效提升操作效率。
本申请实施例提供的技术方案，各步骤的执行主体可以是终端。可选地，终端的触摸显示屏下方设置有指纹识别模组，当用户触摸显示屏时，上述指纹识别模组可以采集到用户的指纹图像。
请参考图1，其示出了本申请一个实施例提供的指纹解锁方法的流程图。该方法包括如下几个步骤(步骤101-104)：
步骤101，在终端处于锁屏状态时，接收对应于负一屏的呼出指示；
锁屏状态是指终端的屏幕被锁定的状态。在终端处于锁屏状态时，终端仅响应部分触发信号，例如点亮屏幕的操作信号，呼出解锁界面的操作信号。在本申请实施例中，终端在处于锁屏状态时响应对应于负一屏的呼出指示。
对应于负一屏的呼出指示用于呼出显示负一屏，其可以是对应于触摸显示屏的触发信号，该触发信号可以是单击操作信号、双击操作信号、滑动操作信号、拖动操作信号、按压操作信号中的任意一种，在本申请实施例中，仅以该呼出指示为滑动操作信号为例进行说明。本申请实施例对滑动操作信号的方向不作限定，例如，该滑动操作信号的方向向右。
步骤102，根据呼出指示显示负一屏；
负一屏是终端中的快捷显示页面，其通常用于显示各类提醒卡片，比如天气、日程安排、应用推荐、提醒事项等等。在本申请实施例中，负一屏包括至少一个快捷图标。上述快捷图标可以是功能图标，也可以是应用图标，本申请实施例对此不作限定。
负一屏所显示的快捷图标可以由用户自定义设定，也可以由终端根据用户的操作习惯统计得到。例如，终端将使用频次大于预设门限的应用图标或功能图标确定为负一屏中的快捷图标；再例如，终端将使用频次排在前n位的应用图标或功能图标确定为负一屏中的快捷图标。上述预设门限，与n均可以根据实际需求设定，本申请实施例对此不作限定。
结合参考图2，其示出了本申请一个实施例提供的负一屏的界面示意图。负一屏21显示有至少一个快捷图标，上述快捷图标包括推荐应用图标、推荐功能图标和日程提醒卡片。
步骤103，在接收到对应于目标快捷图标的第一触发信号时，采集指纹图像。
目标快捷图标可以是上述至少一个快捷图标中的任意一个。当用户期望查看某一快捷图标对应的用户界面，或者使用某一快捷图标所具有的功能时，用户可以选择并触发该快捷图标，用户所触发的快捷图标也即是目标快捷图标。
第一触发信号是触发位置在目标快捷图标上的触发信号，其可以是单击操作信号、双击操作信号、滑动操作信号、拖动操作信号中的任意一种。在本申请实施例中，仅以第一触发信号为单击操作信号进行说明。
在本申请实施例中，由于终端的触摸显示屏下具有指纹识别模组，终端在接收到对应于目标快捷图标的第一触发信号时，通过该指纹识别模组来采集指纹图像。采集指纹图像可以包括如下几个子步骤：
步骤103a，根据第一触发信号开启终端的指纹图像采集功能；
步骤103b，通过终端的指纹图像采集功能采集指纹图像。
在本申请实施例中，终端在接收到第一触发信号时，开启终端中的指纹图像采集功能，并通过该指纹图像采集功能来采集指纹图像。通过上述方式，可以避免终端的指纹图像采集功能始终处于开启状态，从而节省终端的功耗。
可选地，步骤103a可以包括如下两个子步骤：
步骤103a1，将以第一触发信号的触发位置为中心，面积为预设面积的区域确定为第一触发信号对应的触发区域；
第一触发信号的触发位置是指终端接收到第一触发信号时，用户的手指与终端的触摸显示屏相接触的位置。预设面积可以根据实际需求设定，本申请实施例对此不作限定。可选地，预设面积小于终端的触摸显示屏的显示面积。
步骤103a2，开启触发区域的指纹图像采集功能。
此时，步骤103b可以实现为：通过触发区域的指纹图像采集功能采集指纹图像。在本申请实施例中，由于用户的手指与触摸显示屏的接触面积较小，终端仅开启部分区域的指纹图像采集功能，并通过上述部分区域的指纹图像采集功能来采集指纹图像，可以节省终端的功耗。
步骤104，当采集到的指纹图像与预存的指纹图像匹配时，将终端由锁屏状态切换至解锁状态，并显示目标快捷图标对应的用户界面。
预存的指纹图像是指终端中预先存储的指纹图像。当用户第一次启用终端中的指纹识别功能时，终端会提示用户录入指纹，终端通过指纹图像采集功能采集用户录入的指纹图像，上述用户录入的指纹图像也即是预存的指纹图像。预存的指纹图像可以是一个，也可以是多个，本申请实施例对此不作限定。
采集到的指纹图像与预存的指纹图像是否匹配可以采用二者之间的相似度来衡量。若采集到的指纹图像与预存的指纹图像之间的相似度大于第一阈值，则采集到的指纹图像与预存的指纹图像相匹配；若采集到的指纹图像与预存的指纹图像之间的相似度小于或等于第一阈值，则采集到的指纹图像与预存的指纹图像不匹配。当预存的指纹图像存在多个时，终端只要检测到采集到的指纹图像，与任一预存的指纹图像匹配，则执行后续的解锁步骤并显示目标快捷图标对应的用户界面。
在本申请实施例中，终端在用户触发目标快捷图标时，直接通过触摸显示屏下的指纹识别模组采集指纹图像，并在采集到的指纹图像与预存的指纹图像匹配时，直接显示目标快捷图标的用户界面，避免用户需要先对终端进行解锁，然后重新触发目标快捷图标，节省终端在锁屏状态下显示目标快捷图标的用户界面所需的操作，提升操作效率。
结合参考图2，其示出了本申请一个实施例提供的指纹解锁的界面示意图。负一屏21显示有至少一个快捷图标，上述快捷图标包括推荐应用图标、推荐功能图标和日程提醒卡片，当用户采集到对应于目标快捷图标211的第一触发信号时，采集指纹图像，并在采集到的指纹图像与预存的指纹图像匹配时直接显 示目标快捷图标211的用户界面。
综上所述，本申请实施例提供的技术方案，通过在用户呼出显示负一屏并触发负一屏中的某一快捷图标时，终端通过触摸显示屏下设置的指纹识别模组来采集用户的指纹图像，并在采集到的指纹图像与预存的指纹图像匹配时，对终端进行解锁，并直接显示上述快捷图标的用户界面，相比于相关技术中需要用户先对终端进行解锁，然后重新触发快捷图标，本申请实施例提供的技术方案，在终端显示快捷图标的用户界面所需的操作步骤更少，有效提升操作效率。
在实际应用中，有可能出现采集到的指纹图像与预存的指纹图像不匹配的情况，该情况可能是采集到的指纹图像不完整或不清晰导致的，也有可能是终端未预存该输入指纹的用户的指纹图像所导致的。下面对采集到的指纹图像与预存的指纹图像不匹配的情况进行讲解。
在基于图1所示实施例提供的一个可选实施例中，在步骤103之后，该指纹解锁方法还包括如下步骤：
步骤105，当采集到的指纹图像与预存的指纹图像不匹配时，显示提示信息。
采集到的指纹图像与预存的指纹图像不匹配是指采集到的指纹图像与预存的指纹图像之间的相似度小于或等于第一阈值。提示信息用于提示用户重新输入指纹图像。当采集到的指纹图像不完整或者不清晰时，有可能出现采集到的指纹图像与预存的指纹图像不匹配的情况，此时终端提示用户重新输入指纹图像，以避免采集到的指纹图像不完整或者不清晰时，无法对终端进行解锁的情况发生。
步骤106，当采集到的指纹图像与预存的指纹图像不匹配的次数大于预设次数时，显示密码解锁界面，接收在密码解锁界面输入的解锁密码，在输入的解锁密码与预存的解锁密码相同时，从锁屏状态切换至解锁状态，并显示目标快捷图标对应的用户界面。
预设次数可以根据实际需求设定，本申请实施例对此不作限定。密码解锁界面用于供用户输入解锁密码。上述解锁密码可以是数字密码或者手势密码。当解锁密码为数字密码时，密码解锁界面包括数字键盘，以及用于输入数字密码的输入框。当解锁密码为手势密码时，密码解锁界面包括用于输入手势密码的输入框。
当终端未预存输入指纹的用户的指纹图像，或者终端被不法分子获取时，可能会出现采集的指纹图像与预存的指纹图像不匹配的次数达到多次的情况。此时终端无法通过采集到的指纹图像进行解锁时并显示密码解锁界面，用户在密码解锁界面输入解锁密码，若输入的解锁密码正确(也即输入的解锁密码与预存的解锁密码相同)，则终端由锁屏状态切换至解锁状态，并显示目标快捷图标对应的用户界面。
在输入的解锁密码与预存的解锁密码不相同时，显示提示信息，该提示信息用于提示用户重新输入解锁密码。在输入的解锁密码与预存的密码不相同的次数大于预设次数时，则确定终端是被不法分子获取，此时终端启动摄像头来采集输入解锁密码的用户的脸部图像并对终端所处的位置进行定位，之后向目标联系人发送上述脸部图像，以及定位信息。上述目标联系人可以由用户设置，例如公安***。
在实际应用中，有可能出现终端未录入指纹图像的情况，也即终端中未预先存储指纹图像。在该情况下，终端直接采集指纹图像会带来不必要的功耗。针对该情况，终端可以先检测终端中是否存在预存的指纹图像，进而决定是否采用指纹解锁方式对终端进行解锁。
在基于图1所示实施例提供的可选实施例中，在采集指纹图像之前，该指纹解锁方法还包括如下步骤:检测终端中是否存在预存的指纹图像。
若终端中存在预存的指纹图像，则执行采集指纹图像的步骤。若终端中不存在预存的指纹图像，显示密码解锁界面，接收在密码解锁界面输入的解锁密码，在输入的解锁密码与预存的解锁密码相同时，从锁屏状态切换至解锁状态，并显示目标快捷图标对应的用户界面。
终端在检测出未预先存储指纹图像之后，可以显示指纹录入界面，以供用户录入指纹图像。在一种可能的实现方式中，终端在接收到对应于目标快捷图标的结束运行指令时，显示指纹录入界面，该指纹录入界面用于供用户录入指纹图像。其中，对应于目标快捷图标的结束运行指令可以是用于触发返回桌面界面的指令。
终端在锁屏状态下可能会被误触发，例如终端放在口袋里与其它东西接触 导致终端显示负一屏。下面对该种情况进行讲解。
在基于图1所示实施例提供的一个可选实施例中，在步骤103之前，该指纹解锁方法还包括如下步骤：
步骤201，在接收到对应于目标快捷图标的第一触发信号时，检测终端是否处于口袋模式。
口袋模式是指终端处于服装口袋和/或包的概率符合第一预设条件的模式。可选地，步骤201可以包括如下两个子步骤：
步骤201a，获取所述终端的环境信息。
环境信息用于表示终端所处的环境。环境信息包括以下一项或多项的组合：第一运动信息、距离信息、光线信息。
第一运动信息用于表示终端的运动状态。终端的运动状态可以用来表示终端的晃动程度。可选地，终端通过重力传感器获取终端的第一运动信息。终端中设有重力传感器，重力传感器用于测量由于重力引起的加速度，进而计算终端相对于水平面的倾斜角度。可选地，重力传感器每隔预设时间测量上述加速度，并根据相邻两次测量的差值来衡量终端的晃动程度。差值越大，则终端的晃动程度越剧烈；差值越小，则终端的晃动程度较轻。
由于用户使用终端的过程中，终端被握持在用户手上，其通常只会发生小幅度的晃动，然而当终端放置在衣服口袋或者背包中，且因为与衣服口袋或背包发生摩擦而接收到触发信号时，终端的晃动程度会大幅度提升，因此终端的运动状态可以作为确定终端是否处于目标物体中的因素之一。
距离信息用于表示终端与障碍物之间的距离。可选地，终端通过距离传感器获取终端的距离信息。终端设有距离传感器。可选地，该距离传感器中的发射部件发射激光，障碍物会反射该激光，由距离传感器中的接收部件接收反射后的激光，之后根据反射激光到接收激光的激光传输时间来确定终端与障碍物之间的距离。激光传输时间越长，则终端与障碍物之间的距离越长；激光传输时间越短，则终端与障碍物之间的距离越短。
当终端处于衣服口袋或者包中的时候，终端的多个方向均存在障碍物，且障碍物与终端之间的距离较近，因此终端与障碍物之间的距离可以作为判断终端是否处于目标物体中的因素之一。
光线信息用于表示终端所处的环境的光线强度。可选地，终端通过光传感 器获取终端的光线信息。终端设有光传感器，光传感器中存在光敏元件，该光敏元件能够检测不同波长的光的光能量，并将光能量转换成电信号，之后根据电信号的大小来确定光线强度。
当终端处于衣服口袋或包中时，终端所处的环境通常是全封闭或者半封闭时的，由于外界的光线大部分被衣服口袋或者包而遮挡住，因此终端所处的环境的光线强度较弱，因此终端所处的环境的光线强度也可以作为判断终端是否处于目标物体中的因素之一。
可选地，环境信息还可以包括摄像头采集的图像。另外，当触发信号作用于指纹传感器时，环境信息还可以包括指纹传感器采集的数据。本申请实施例对此不作限定。
步骤201b，根据环境信息检测终端是否处于口袋模式。
上文实施例中介绍了终端处于背包中时的各项环境特征(例如终端的晃动终端较大、终端与障碍物之间的距离较小、终端所处的环境的光线强度较弱)，之后终端可以将采集到的环境信息与上述各项环境特征进行逐一比对，进而判断终端是否放置在目标物体中。
可选地，步骤201b包括如下几个子步骤：
步骤201b1，根据第一运动信息，检测终端的运动状态是否满足第一预设条件。
第一预设条件是指终端的晃动程度大于一定程度。可选地，当终端的晃动程度用两次测量的差值来衡量时，第一预设条件是指上述差值大于第一阈值，第一阈值可以根据实际需求设定，本申请实施例对此不作限定。
若终端的运动状态不满足第一预设条件，则认为终端没有出现误触情况，并结束流程；若终端的运动状态满足第一预设条件，则执行步骤301b2。
步骤201b2，根据距离信息，检测终端与障碍物之间的距离是否小于第一门限值。
第一门限值可以根据实际需求设定，本申请实施例对此不作限定。
若终端与障碍物之间的距离小于第一门限值，则认为终端没有出现误触情况，并结束流程；若终端与障碍物之间的距离大于第一门限值，，则执行步骤301b3。
步骤201b3，根据光照信息，检测终端所处的环境的光线强度是否小于第二 门限值。
第二门限值可以根据实际需求设定，本申请实施例对此不作限定。
若终端所处的环境的光线强度大于第二门限值，则认为终端没有出现误触情况，并结束流程；若终端所处的环境的光线强度小于第二门限值，则确定终端处于口袋模式。
此外，当环境信息包括指纹传感器采集到的数据时，终端还可以检测上述采集的数据是否是指纹数据，若上述采集的数据不是指纹数据，则说明终端出现误触情况。
另外，需要说明的是，本申请实施例对上述三种判断终端是否处于目标物体中的判断顺序不作限定，上文实施例介绍的仅是示例性地。在一种可能的实现方式中，终端还可以根据光照信息，检测终端所处的环境的光线强度是否小于第二门限值；若终端所处的环境的光线强度小于第二门限值，则根据距离信息，检测终端与障碍物之间的距离是否小于第一门限值；若终端与障碍物之间的距离小于第一门限值，则根据第一运动信息，检测终端的运动状态是否满足第一预设条件；若终端的运动状态满足第一预设条件，则确定终端处于口袋模式。
当终端处于口袋模式时，终端显示负一屏，以及接收到对应于目标快捷图标的第一触发信号时，均被认为是误触发导致的，此时终端不执行后续流程。当终端未处于口袋模式时，则执行后续采集指纹图像的流程。
用户可以在终端设置预存的指纹图像与使用权限之间的对应关系，以避免其他用户不合理的使用终端，可以有效保护隐私。
在基于图1所示实施例提供的一个可选实施例中，在步骤104之前，该指纹解锁方法还包括如下步骤：
步骤301，当采集到的指纹图像与预存的指纹图像匹配时，检测与采集到的指纹图像匹配的预存的指纹图像是否具有目标快捷图标的使用权限。
用户可以在终端设置预存的指纹图像与使用权限之间的对应关系。示例性地，上述对应关系可以参考如下表-1：
表-1
终端在采集到的指纹图像与预存的指纹图像匹配时，查找上述对应关系，以检测与采集到的指纹图像匹配的预存的指纹图像是否具有目标快捷图标的使用权限。
若与采集到的指纹图像匹配的预存的指纹图像具有目标快捷图标的使用权限，则执行将终端由锁屏状态切换至解锁状态，并显示目标快捷图标对应的用户界面的步骤。若与采集到的指纹图像匹配的预存的指纹图像不有目标快捷图标的使用权限，则结束流程。
请参考图3，其示出了本申请一个实施例示出的指纹解锁方法的流程图。该方法包括如下步骤：
步骤301，在终端处于锁屏状态时，接收对应于负一屏的呼出指示。
步骤302，根据呼出指示显示负一屏，负一屏包括至少一个快捷图标。
步骤303，在接收到对应于目标快捷图标的第一触发信号时，检测终端是否处于口袋模式。
步骤304，若终端未处于口袋模式，则采集指纹图像。
若终端处于口袋模式，则结束流程。
