具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
以下分别进行详细说明。

以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端设备，又称之为用户设备(User Equipment，UE)，是一种向用 户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
请参见图1和图1.1，图1和图1.1为本发明实施例提供的一种触控解锁方法的流程示意图，包括以下步骤：
S101、当终端设备处于熄屏状态且检测到用户针对终端设备的指纹识别模组的触控按压操作时，终端设备获取原始指纹图像并触发中断请求，针对所述原始指纹图像执行指纹识别处理。
S102、若检测到所述指纹识别处理的结果为匹配，则终端设备点亮所述终端设备的屏幕。
具体地，上述指纹识别模组可以与dome键集成在一起，当终端设备处于熄屏状态时，为了解锁亮屏，用户需通过按压dome键来实现解锁亮屏，现有的流程是：按压中断—手指触摸—获取指纹图像—指纹识别—解锁亮屏，现有熄屏按压解锁的解锁时间是从按压中断到解锁亮屏所需的时间。目前，按压亮屏的时间在60-100ms，获取指纹图像到匹配需要100ms，因此现有熄屏按压解锁的解锁时间是以上时间相加。熄屏按压解锁用户能够感知的是dome键按压瞬间和亮屏瞬间，但是在用户按压dome之前，是用户的手指先触碰到dome键的，为了缩短熄屏按压解锁所需要的时间，当终端设备检测到用户针对dome的触控操作时，终端设备获取原始指纹图像，针对所述原始指纹图像执行指纹识别处理；在终端设备获取原始指纹图像，针对所述原始指纹图像执行指纹识别处理这个过程中，或是该过程之前终端设备若检测到用户针对dome的按压操作时，终端设备触发中断请求(Interrupt Request，IRQ)，其中，终端设备处于熄屏，休眠(suspend)状态，通过IRQ中断指令中断终端设备的硬件休眠状态，唤醒(resume)系统，原始指纹图像指的是终端设备刚开始采集到的用户手指的指纹图像，即未进行图像处理之前的图像。
与现有流程相比，本发明将熄屏按压解锁分为两部分，一部分是手指触摸—获取指纹图像—指纹识别—解锁亮屏，另一部分是按压中断—亮屏，且该两部分是同时进行，因此熄屏按压解锁只需要考虑指纹解锁的时间100ms，按压 亮屏60-100ms即可省下来，进而缩短了熄屏按压解锁所需要的时间，进而提高用户的体验。
在以上步骤S101中，举例来说，请参见图2，终端设备针对所述原始指纹图像执行指纹识别处理的具体实现方式为：
S101-1、终端设备针对所述原始指纹图像执行图像增强处理，以生成目标指纹图像。
S101-2、终端设备将所述目标指纹图像与预存的注册指纹模板进行特征点匹配。
若所述目标指纹图像与预存的注册指纹模板的特征点相匹配的比例大于或等于预设阈值时，则匹配成功；若所述目标指纹图像与预存的注册指纹模板的特征点相匹配的比例小于预设阈值时，则匹配失败。
具体地，为了降低拒识率(false rejection rate，FRR)：是指将相同的指纹误认为是不同的，而加以拒绝的出错概率。FRR＝(拒识的指纹数目/考察的指纹总数目)×100％，或提高误识率(false accept rate，FAR)：是指将不同的指纹误认为是相同的指纹，而加以接收的出错概率。FAR＝(错判的指纹数目/考察的指纹总数目)×100％，在指纹识别之前，终端设备需对原始指纹图像进行图像增强处理，得到目标指纹图像，然后终端设备将目标指纹图像与预存的注册指纹模板进行特征点匹配，若目标指纹图像与预存的注册指纹模板的特征点相匹配的比例大于或等于预设阈值时，则匹配成功；若目标指纹图像与预存的注册指纹模板的特征点相匹配的比例小于预设阈值时，则匹配失败。由于，指纹匹配时间占熄屏解锁时间的1/3，为了更进一步的缩短熄屏解锁时间，可根据FRR和阀值的曲线图，FRR从1％提高到0.1％，降低匹配预设阀值(比如匹配预设阈值从80％降到70％或是其他值)，匹配时间可至少减少30ms，而此时FRR提高变成0.1％，用户体验度也提高，弊端是FAR会降低，1/5万，变差成1/1万，此安全等级与四位数字密码安全等级也是一样的，并不会造成过多用户安全上的问题。另外，对应指纹支付方面，由于指纹支付更多关注安全性问题而不是解锁时间，在这种情况下，不通过修改FAR来提高解锁时间。
举例来说，请参见图3，所述预存的注册指纹模板的数量为N，所述N为 大于1的整数，终端设备将所述目标指纹图像与预存的注册指纹模板进行特征点匹配的具体实施方式为：
S101-21、终端设备获取N个预存的注册指纹模板在预设时间范围内被匹配的次数。
S101-22、终端设备按照所述N个预存的注册指纹模板在预设时间范围内被匹配的次数高低顺序，对所述N个预存的注册指纹模板进行排序。
S101-23、终端设备依次将所述目标指纹图像与排序后的所述N个预存的注册指纹模板进行特征点匹配。
具体地，目前终端设备一般都支持多个指纹注册，也就是说用户可以往终端设备里面注册2个或2个以上的指纹，一般上限是在8个左右，而每个注册指纹模板图片差不多有20张指纹图像左右，可见注册的指纹越多，指纹解锁时匹配时间就越长，一般如果只注册了一个指纹，指纹解锁时，只需要和该一个注册的指纹的20张图片去匹配，速度很快，一般在60-80ms左右，但是如果注册了5个指纹的话，就要把5个指纹的模板依次和本次解锁的指纹去匹配，时间就会成倍延长。
若该终端设备的预存的注册模板为N个时，为了加快指纹识别的速度，可先对N个预存的注册指纹模板进行一个优先级排序，其具体的实现方式可以是：终端设备先获取N个预存的注册指纹模板在预设时间范围(比如1个月)内被匹配的次数，然后终端设备根据N个预存的注册指纹模板在预设时间范围内被匹配的次数高低顺序，对N个预存的注册指纹模板进行排序(比如注册指纹模板包括指纹模板1、指纹模板2和指纹模板3，假设在一个月内指纹模板1被匹配的次数为100次，指纹模板2被匹配的次数为10次，指纹模板3被匹配的次数为5次，则排序为指纹模板1--指纹模板2--指纹模板3)，最后终端设备依次将目标指纹图像与排序后的N个预存的注册指纹模板进行特征点匹配(比如先将目标指纹图像与指纹模板1进行匹配，若目标指纹图像与指纹模板1匹配成功，则停止匹配，若匹配不成功，则将目标指纹图像与指纹模板2进行匹配，以此类推)。
若该终端设备的预存的注册模板为N个时，为了加快指纹识别的速度，可先对N个预存的注册指纹模板进行一个优先级排序，其具体的实现方式可 以是：终端设备先获取N个预存的注册指纹模板注册时设定的优先级，然后终端设备根据N个预存的注册指纹模板注册时设定的优先级的高低顺序(优先级包括优先级1、优先级2、优先级3，其中优先级1比优先级2等级高，以此类推)，对N个预存的注册指纹模板排序(比如注册指纹模板包括指纹模板1、指纹模板2和指纹模板3，指纹模板1对应的优先级为优先级1、指纹模板2对应的优先级为优先级2、指纹模板3对应的优先级为优先级3，则排序为指纹模板1--指纹模板2--指纹模板3)，最后终端设备依次将目标指纹图像与排序后的N个预存的注册指纹模板进行特征点匹配(比如先将目标指纹图像与指纹模板1进行匹配，若目标指纹图像与指纹模板1匹配成功，则停止匹配，若匹配不成功，则将目标指纹图像与指纹模板2进行匹配，以此类推)。
在以上步骤S102中，终端设备点亮所述终端设备的屏幕的具体实施方式为：终端设备获取当前环境的光亮度，以及根据所述当前环境的光亮度点亮所述终端设备的屏幕。
具体地，目前的终端设备为了保护眼睛，一般都设有自动调节屏幕亮度的功能，当终端设备开启了自动感光功能时，终端设备先通过光传感器获取当前环境的光亮度，然后终端设备根据光亮度与屏幕的亮度的映射关系，确定与当前环境亮度对应的目标屏幕的亮度，最后终端设备根据目标屏幕的亮度点亮终端设备的屏幕，以达到提高用户体验以及保护用户眼睛的效果。
可选的，在步骤S102终端设备点亮所述终端设备的屏幕之后，图1所示的触控解锁方法还包括：加载所述终端设备前一次锁屏时正在运行的应用；或者，加载与所述目标指纹图像绑定的应用。
具体地，在步骤S102终端设备点亮所述终端设备的屏幕之后，为了提高用户体验，终端设备可加载终端设备前一次锁屏时正在运行的应用(其具体实现方式为终端设备获取终端设备前一次锁屏时正在运行的应用的页面，在终端设备点亮屏幕后，直接显示终端设备前一次锁屏时正在运行的应用的页面)；或者，终端设备加载与所述目标指纹图像绑定的应用(其具体实现方式为：终端设备获取与目标指纹图像绑定的应用，然后启动该应用，或者，终端设备获取与目标指纹图像绑定的应用，以及获取与目标指纹图像绑定的应用前一次打开时的页面，然后加载该应用前一次打开时的页面)。
可以看出，本发明实施例将熄屏按压解锁流程分为：触控操作—采取指纹图像—指纹识别—解锁亮屏和按压中断—亮屏两个执行动作，且该两个执行动作是同时进行的，与现有的熄屏按压解锁流程：按压中断—触控操作—采取指纹图像—指纹识别—解锁亮屏相比，显然本发明的熄屏按压解锁所需要的时间更短，进而提高用户的体验。
