Description

控制方法、装置、设备和存储介质 技术领域
本申请涉及计算机技术领域，例如涉及控制方法、装置、设备和存储介质。
背景技术
市场上已经存在一些防误触方案，比如“口袋模式”：利用光感和距离感应器实现在触发“口袋模式”后屏幕不可用；“边缘防误触”：分析触控点位移，对于会产生位移的触控点，系统将当前触控识别为有效触控，执行触控响应，对于固定无位移的触控点，系统将当前触控判断为误触，不响应；另一种“边缘防误触”的实现方式是设置无效区域。
相关技术中，通话防误触主要采用的是近感灭屏方案，即在终端设备处于通话状态下，当终端设备贴近耳朵时终端设备的屏幕熄灭，当终端设备远离耳朵时点亮终端设备的屏幕。近感灭屏方案的实现依赖于距离传感器，但由于距离传感器的局限性(sensor误报、判断距离限制等)，存在识别失败的情况。在一些情况下，终端设备稍微抖动偏移就会触发近感远离，屏幕就会被点亮，这时候因为屏幕被点亮，终端设备切换为可交互状态，就会触发误触操作，且因为距离传感器是基于光感实现的，油污和光线等也会对距离传感器有较大影响，导致触发误触操作。
发明内容

在一个示例性实施方式中，图1为本申请实施例提供的一种控制方法的流程示意图，该方法可以适用于对终端设备进行控制的情况，该方法可以由控制装置执行，该控制装置可以由软件和/或硬件实现，并集成在终端设备上，所述终端设备可以为手机。
如图1所示，本申请提供的控制方法，包括S110和S120。
S110、当终端设备处于通话状态且满足屏幕状态切换条件时，则获取距离屏幕最近的用户的面部特征数据。
所述屏幕状态切换条件可以为近感远离被触发，也可以为检测到所述终端设备由运动状态切换到静止状态，或者可以为近感靠近被触发，还可以为一动作的结束，本申请实施例对此不进行限制。
获取距离屏幕最近的用户的面部特征数据的方式可以为通过终端设备的屏下摄像头采集距离屏幕最近的用户的面部特征数据，获取距离屏幕最近的用户的面部特征数据的方式还可以为通过终端设备的前置摄像头采集距离屏幕最近的用户的面部特征数据。
所述用户的面部特征数据可以为用户的面部图像，也可以为从用户的面部图像中提取出的能够表征用户面部特征的数据，例如可以是，用户的眼睛对应的特征数据、用户的鼻子对应的特征数据，用户的耳朵对应的特征数据以及用户的头发对应的特征数据等。
所述终端设备可以为具有打电话功能的设备，包括手机、平板以及智能手表等。
当终端设备处于通话状态且满足屏幕状态切换条件时，则获取距离屏幕最近的用户的面部特征数据，例如可以是，当手机处于通话状态且近感远离被触发时，则通过前置摄像头采集距离屏幕最近的用户的面部特征数据。
在一个例子中，当终端设备处于通话状态且检测到所述终端设备由运动状态切换到静止状态时，则通过终端设备的屏下摄像头采集距离屏幕最近的用户的面部特征数据。
S120、若所述用户的面部特征数据为侧面面部特征数据，则控制所述终端设备的屏幕处于息屏状态。
控制所述终端设备的屏幕处于息屏状态的方式可以为：预先获取所述终端设备的屏幕的当前状态，若所述终端设备的屏幕的当前状态为息屏状态，则保持当前屏幕状态不变，若所述终端设备的屏幕的当前状态为亮屏状态，则将所述终端设备的屏幕的当前状态从亮屏状态切换至息屏状态。控制所述终端设备的屏幕处于息屏状态的方式还可以为：直接控制终端设备的屏幕处于息屏状态。
若所述用户的面部特征数据为侧面面部特征数据，则控制所述终端设备的屏幕处于息屏状态的方式可以为：将用户的面部特征数据和事先存储的正面面部特征数据进行比较，若用户的面部特征数据和事先存储的正面面部特征数据的相似度小于第一阈值，则确定用户的面部特征数据为侧面面部特征数据；若所述用户的面部特征数据为侧面面部特征数据，则控制所述终端设备的屏幕处于息屏状态的方式还可以为：对用户的面部特征数据进行特征提取，得到至少一个目标面部特征元素，若至少一个目标面部特征元素和预存正面面部特征元素集合中对应特征元素的相似度小于第二阈值，则确定所述用户的面部特征数据为侧面面部特征数据；若所述用户的面部特征数据为侧面面部特征数据，则控制所述终端设备的屏幕处于息屏状态的方式还可以为：获取所述用户的面部 特征数据中预设面部特征元素的数量，若所述用户的面部特征数据中预设面部特征元素的数量小于数量阈值，则确定所述用户的面部特征数据为侧面面部特征数据；若所述用户的面部特征数据为侧面面部特征数据，则控制所述终端设备的屏幕处于息屏状态的方式还可以为：获取所述用户的面部特征数据中预设面部特征元素的面积，若所述用户的面部特征数据中预设面部特征元素的面积小于面积阈值，则确定所述用户的面部特征数据为侧面面部特征数据。
在一个例子中，面部特征数据的认定原理是：比较正面面部特征数据和用户的面部特征数据的差异，根据该差异判定用户的面部特征数据是侧面面部特征数据还是正面面部特征数据。方法1：事先录入正面面部特征数据(正面面部特征数据包括面部特征元素，例如眼睛，鼻子，耳朵，以及头发等)并存入面部特征库，当需要对用户的面部特征数据进行判定时，用户面部特征数据提取模块提取用户的面部特征数据中的目标面部特征元素，并将目标面部特征元素和预存正面面部特征元素集合中对应的特征元素进行比较，如果任意目标面部特征元素(比如眼睛、鼻子、耳朵、或头发等)和预存正面面部特征元素集合中对应特征元素的匹配度较低，比如匹配度低于60％，则认定用户的面部特征数据为侧面面部特征数据，如果每个目标面部特征元素(比如眼睛、鼻子、耳朵、以及头发等)和预存正面面部特征元素集合中对应的特征元素的匹配度较高，则认为用户的面部特征数据为非侧面面部特征数据。方法2：对距离屏幕最近的用户的面部特征数据进行提取，得到眼睛的数量，若眼睛的数量为0或1，则认定为用户的面部特征数据为侧面面部特征数据，若眼睛的数量不为0且不为1，则认为用户的面部特征数据为非侧面面部特征数据。
面部特征数据提取匹配方法：此方法主要用于面部特征数据的认定。方法1：对当前录入的用户的面部特征数据进行提取得到至少一个目标面部特征元素，并对至少一个目标面部特征元素归类存储，将每一个目标面部特征元素(比如眼睛)和面部特征库中的同类正面面部特征列表匹配(可能录入多张面部特征，所以是一个列表)，若每一个目标面部特征元素与面部特征库中的对应的特征元素的相似度较低，说明用户的面部特征数据为侧面面部特征数据，若至少存在一个目标面部特征元素与面部特征库中的对应的特征元素的相似度较高，则用户的面部特征数据为非侧面面部特征数据。
本申请提供的一种控制方法，通过当终端设备处于通话状态且满足屏幕状态切换条件时，则获取距离屏幕最近的用户的面部特征数据，若所述用户的面部特征数据为侧面面部特征数据，则控制所述终端设备的屏幕处于息屏状态，既解决了距离传感器的局限性(sensor误报、判断距离限制等)导致误触发近感远离，屏幕点亮，进而终端设备切换为可交互状态，触发误触操作的问题，又能够解决因为距离传感器是基于光感实现的，油污和光线等也会对距离传感器 有较大影响，导致触发误触操作的问题，能够有效避免触发误触操作，提高用户体验。

在一个实施例中，所述屏幕状态切换条件包括：
近感远离被触发；或者，检测到所述终端设备由运动状态切换到静止状态；或者，近感靠近被触发。
本申请实施例提出了方案一、和近感灭屏方案配合使用。在终端设备处于通话状态的情况下，当前是近感靠近状态(息屏)，在近感远离触发时，不是立即点亮屏幕，而是启动摄像头去捕捉距离屏幕最近的用户的面部特征数据，如果用户的面部特征数据为侧面面部特征数据，则保持息屏状态，如果用户的 面部特征数据为非侧面面部特征数据，则点亮屏幕。方案二、完全不使用近感，在终端设备处于通话状态的情况下，当检测到手机由运动状态转换到静止状态，启动相机捕捉距离屏幕最近的用户的面部特征数据，如果用户的面部特征数据为侧面面部特征数据，则熄灭屏幕；如果用户的面部特征数据为非侧面面部特征数据，则点亮屏幕。在一个例子中，如图1a所示，屏幕状态控制装置包括：通话模块、距离感应模块、用户面部特征数据提取模块、正面面部特征数据存储模块、用户面部特征数据判定模块和亮灭屏管理模块，其中，通话模块设置为通话发起。距离感应模块主要是距离传感器，设置为识别是近感靠近还是近感远离，将识别结果作为点亮或熄灭屏幕的依据。用户面部特征数据提取模块调用相机录入的正面面部特征数据(特征元素，眼睛，鼻子，耳朵，头发等)，用来构建面部特征库，面部特征元素提取可以采用当前成熟的面部识别算法。面部特征存储模块还有一个功能，距离感应模块或运动检测模块判定需要提取面部特征时，正面面部特征数据存储模块还设置为摄取面部特征。用户面部特征数据判定模块根据用户面部特征数据提取模块提取的面部特征，判断提取的面部特征是否是侧面面部特征，若提取的面部特征是侧面面部特征则点亮屏幕，若提取的面部特征不是侧面面部特征则熄灭屏幕。上述判断方法包括：方法1和方法2两种判断方法，方法1：事先录入正面面部特征数据(正面面部特征数据包括面部特征元素，例如眼睛，鼻子，耳朵，以及头发等)并存入面部特征库，当需要对用户的面部特征数据进行判定时，用户面部特征数据提取模块提取用户的面部特征数据中的目标面部特征元素，并将目标面部特征元素和预存正面面部特征元素集合中对应的特征元素进行比较，如果任意目标面部特征元素(比如眼睛、鼻子、耳朵、或头发等)和预存正面面部特征元素集合中对应特征元素匹配度较低，比如匹配度低于60％，则认定用户的面部特征数据为侧面面部特征数据，如果每个目标面部特征元素(比如眼睛、鼻子、耳朵、以及头发等)和预存正面面部特征元素集合中对应的特征元素的匹配度较高，则认为用户的面部特征数据为非侧面面部特征数据。方法2：对距离屏幕最近的用户的面部特征数据进行提取，得到眼睛的数量，若眼睛的数量为0或1，则认定为用户的面部特征数据为侧面面部特征数据，若眼睛的数量不为0且不为1，则认为用户的面部特征数据为非侧面面部特征数据。亮灭屏管理模块设置为执行点亮屏幕或熄灭屏幕的操作。如图1b所示，另一种屏幕状态控制装置包括：通话模块、运动检测模块、用户面部特征数据提取模块、正面面部特征数据存储模块、用户面部特征数据判定模块和亮灭屏管理模块，当运动检测模块检测到手机由运动状态切换到静止状态(或接近静止)，启动相机抓取距离屏幕最近的用户的面部特征数据，手机运动状态检测可以根据重力加速度传感器(Gravity sensor，G-sensor)来判断。
在另一个例子中，如图1c所示，正面面部特征数据录入的操作用于提前录入用户的正面面部特征数据，并将录入的正面面部特征数据存储在正面面部特征数据存储模块，用于在执行面部特征数据的认定方法1时作为比较的依据，当捕捉的距离屏幕最近的用户的面部特征数据和存储的正面面部特征数据差别比较大时则认定用户的面部特征数据为侧面面部特征数据。录入正面面部特征数据时可以从不同距离和角度尽量多地录入用户的正面面部图像，系统根据面部识别算法对正面面部图像中的面部特征元素进行提取并归类(比如眼睛一类，耳朵一类等等)。
当终端设备来电接通后，也就是终端设备处于通话状态时，判断是否触发近感，当通话中的手机贴近耳朵时会触发近感靠近，屏幕息屏；当通话中的手机远离耳朵时则触发近感远离，屏幕点亮。实际操作时，手机稍微抖动远离耳朵可能就会触发近感远离，这时就会发生误触。当触发近感远离时，要触发面部特征识别，获取距离屏幕最近的用户的面部特征数据，而不是直接去亮屏，将距离屏幕最近的用户的面部特征数据和面部特征库里的模型比对，若所述用户的面部特征数据为侧面面部特征数据，则控制所述终端设备的屏幕处于息屏状态。
如图1d所示，当终端设备来电接通后，也就是终端设备处于通话状态时，若检测到目标动作的结束(手机运动状态可以根据G-sensor判断)，触发面部特征提取，获取距离屏幕最近的用户的面部特征数据，将距离屏幕最近的用户的面部特征数据和面部特征库里的模型比对，如果用户的面部特征数据为侧面面部特征数据，则控制所述终端设备的屏幕处于息屏状态，保持当前屏幕状态(灭屏)，如果用户的面部特征数据为非侧面面部特征数据，则点亮屏幕。例如可以是，目标动作的结束可以为：手机状态由运动状态切换到静止或相对接近静止状态。
