具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
诸如手机、平板电脑之类的终端设备通常都配备有指纹识别传感器，以实现指纹识别功能。指纹识别传感器包括光学指纹识别传感器、电容式指纹识别传感器、超声波指纹识别传感器等类型。无论是何种类型的指纹识别传感器，其原理基本相同，均是扫描皮肤表面凹凸不平的纹路得到指纹图像。如图1所示，其示例性地示出了一种指纹图像的示意图，指纹图像中记录有指纹的脊线11(即图中黑色线条)和谷线12(即图中黑色线条之间的白色区域)。在进行指纹匹配时，从指纹图像中识别出指纹的细节特征点，通过比较不同指纹 的细节特征点，得到指纹匹配结果。指纹的细节特征点包括脊线的端点、分叉点、结合点和断点等。
在本文中提及的“指纹”通常是指用户手指的纹路，但并不限定也可以是用户的其它身体部位的纹路，如手掌。
本公开提供的技术方案，依据指纹识别传感器采集的指纹图像，实现对触控压力进行检测。下面，通过几个实施例对本公开提供的技术方案进行介绍和说明。
图2是根据一示例性实施例示出的一种压力检测方法的流程图。该压力检测方法可应用于配置有指纹识别传感器的终端设备中。例如，终端设备可以是手机、平板电脑、可穿戴设备等。该压力检测方法可以包括如下几个步骤。
在步骤202中，通过指纹识别传感器依次采集n帧指纹图像，n≥2且n为整数。
在步骤204中，分别获取每一帧指纹图像中的指纹的面积。
在步骤206中，根据面积在n帧指纹图像中的变化趋势，确定作用于指纹识别传感器的压力的变化趋势。
综上所述，本实施例提供的压力检测方法，通过获取指纹图像中的指纹的面积，并根据指纹的面积在多帧指纹图像中的变化趋势，确定作用于指纹识别传感器的压力的变化趋势；解决了相关技术中需要在终端设备中设置专门的压力感应模组才能实现压力检测功能，导致终端设备存在体积大，不够轻便，且成本高的问题；省去了压力感应模组，有助于终端设备的结构设计更为轻便，降低成本。
图3是根据另一示例性实施例示出的一种压力检测方法的流程图。该压力检测方法可应用于配置有指纹识别传感器的终端设备中。例如，终端设备可以是手机、平板电脑、可穿戴设备等。该压力检测方法可以包括如下几个步骤。
在步骤301中，通过指纹识别传感器依次采集n帧指纹图像，n≥2且n为整数。
终端设备通过指纹识别传感器依次采集n帧指纹图像。指纹图像中记录有指纹，指纹图像中记录的指纹的面积，与皮肤表面和指纹识别传感器之间的接触面积基本相同。
在步骤302中，分别获取每一帧指纹图像中的指纹的面积。
终端设备分别获取每一帧指纹图像中的指纹的面积。由于诸如手指之类的身体部位的皮肤表面是非平面的且是可形变的，而指纹识别传感器的表面为一固定平面，因此皮肤表面在与指纹识别传感器接触的过程中，两者的接触面面积会随着触控压力的增大而增大。在本实施例中，通过对指纹的面积在多帧指纹图像中的变化趋势进行分析，实现对触控压力的变化趋势进行检测。
在步骤303中，根据面积在n帧指纹图像中的变化趋势，确定作用于指纹识别传感器的压力的变化趋势。
终端设备根据指纹的面积在n帧指纹图像中的变化趋势，确定作用于指纹识别传感器的压力的变化趋势。若指纹的面积在n帧指纹图像中的变化趋势为逐渐增大，则终端设备确定作用于指纹识别传感器的压力的变化趋势为逐渐增大；反之，若指纹的面积在n帧指纹图像中的变化趋势为逐渐减小，则终端设备确定作用于指纹识别传感器的压力的变化趋势为逐渐减小。
此外，压力的变化趋势可以逻辑电平信号表示。例如，逻辑电平信号1表示压力的变化趋势为逐渐增大，逻辑电平信号0表示压力的变化趋势为逐渐减小。
在步骤304中，执行与压力的变化趋势相对应的控制操作。
终端设备执行与压力的变化趋势相对应的控制操作。例如，终端设备根据压力的变化趋势，调节音量或者屏幕亮度等。比如，当压力逐渐增大时，控制音量逐渐增大；反之，当压力逐渐减小时，控制音量逐渐减小。
压力的变化趋势与控制操作之间的对应关系可预先设定并存储至终端设备，或者也可由用户自定义设定，本实施例对此不作限定。
可选地，终端设备在获取指纹的面积之后，还可根据预定对应关系，获取与该面积对应的压力等级。其中，预定对应关系包括至少一组面积和压力等级之间的对应关系。通过上述方式，实现对触控压力进行等级量化，估算压力大小。在实际应用中，上述预定对应关系可预先根据大量实验数据进行设定并存储至终端设备，或者也可由用户自定义设定。
可选地，终端设备在获取压力等级之后，还可执行与该压力等级相对应的控制操作。终端设备存储至少一组压力等级与控制操作之间的对应关系。例如，压力等级1对应控制终端设备关机，压力等级2对应控制终端设备开启，压力等级3对应控制终端设备重启。上述对应关系可预先设定并存储至终端设备，或者也可由用户自定义设定，本实施例对此不作限定。
综上所述，本实施例提供的压力检测方法，通过获取指纹图像中的指纹的面积，并根据指纹的面积在多帧指纹图像中的变化趋势，确定作用于指纹识别传感器的压力的变化趋势；解决了相关技术中需要在终端设备中设置专门的压力感应模组才能实现压力检测功能，导致终端设备存在体积大，不够轻便，且成本高的问题；省去了压力感应模组，有助于终端设备的结构设计更为轻便，降低成本。
另外，本实施例提供的压力检测方法，还通过根据预定对应关系，获取与该面积对应的压力等级，实现了对触控压力进行等级量化，估算压力大小。
