具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
目前，移动终端在接近识别场景所采用的方案包括微缝红外方案、TP+红外方案、超声波接近技术方案以及传统红外方案等。其中，传统红外方案因为要占用移动终端的正面屏幕的空间基本已经被抛弃；微缝红外方案对结构要求很高，一般情况下达不到要求，所以也很少采用；TP+红外方案的识别率有待提高，且抗干扰能力差；而使用超声波接近技术因为其抗干扰能力强、识别率高等优势被越来越重视并被采用。
其中，超声波接近检测是通过从麦克风拾取超声波，再将超声波发送给识别模块处理，识别模块根据连续的超声信号作为接近判断的依据。具体地，移动终端同时包括超声波发送模块和超声波接收模块，在超声波发送模块相对物体运动的过程中，其实质是移动终端相对物体运动，从而超声波接收模块也相对物体运动。如图1所示，图1示出了本申请实施例提供的多普勒效应的示意图，根据多普勒效应，物体辐射的波长因为波源(移动终端)和观测者(物体)的相对运动而产生变化，多普勒效应公式如下：
Figure PCTCN2020113281-appb-000001
其中，f'为观察到的频率、f为发射源于该介质中的原始发射频率、v为波在该介质中的传播速度、v 0为观察者移动速度，若观察者接近发射源则前方运算符号为+号,反之则为-号；v s为发射源移动速度，若物体接近观察者则前方运算符号为-号，反之则为+号。由多普勒效应公式可知，当发射源与观察者相对接近时，观察者接收到的信号频率会变大；当发射源与观察者相对远离时，观察者接收到的信号频率会变小；当发射源与观察者相对静止时，观察者接收到信号频率与发射源一致。
具体地，请参阅图2，图2示出了本申请实施例提供的超声波的传播路径的示意图，移动终端可以通过超射波发送模块(如听筒、喇叭、专用超声波发射器等)发射超声波，一部分超声波通过空气传播直达超声波接收模块(拾音器)(如图2的路径1)，一部分超声波通过空气传播与物体形成反射后再到达超声波接收模块(如图2的路径2)。超声波接收模块拾取到的是直达声和反射声的叠加信号，经过A/D转换器转化为音频信号，通过算法处理音频数据得到物体相对移动终端的运行状态，进而指导移动终端的屏幕处于点亮状态或熄灭状态。
然而，在某些特殊的场景下，移动终端会因为***负载过大导致超声波丢帧，进而影响移动终端对于物体相对运动状态识别的准确率，针对上述问题，发明人发现可以尽量设置比较高的***频率和吞吐量，确保在大多数情况下不会发生丢帧的情况，但是在某些极端的场景下，***仍然存在丢帧的情况，并且仅仅通过经验值来设置固定参数，设置的太小可能存在丢帧，设置的太大又存在资源浪费、功耗增加的问题。因此，针对上述问题，发明人经过长期的研究发现，并提出了本申请实施例提供的基于超声波的丢帧处理方法、装置、移动终端及存储介质，通过移动终端的负载率和丢帧率智能调节***效能以降低丢帧率，提高用户体验。其中，具体的基于超声波的丢帧处理方法在后续的实施例中进行详细的说明。
请参阅图3，图3示出了本申请一个实施例提供的基于超声波的丢帧处理方法的流程示意图。所述基于超声波的丢帧处理方法用于通过移动终端的负载率和丢帧率智能调节***效能以降低丢帧率，提高用户体验。在具体的实施例中，所述基于超声波的丢帧处理方法应用于如图5所示的基于超声波的丢帧处理装置200以及配置有所述基于超声波的丢帧处理装置200的移动终端(图6)。下面将以移动终端为例，说明本实施例的具体流程，当然，可以理解的，本实施例所应用的移动终端可以为智能手机、平板电脑、穿戴式电子设备等，在此不做限定。其中，在本实施例中，该移动终端可以包括超声波接收模块和超声波接近计算模块，下面将针对图3所示的流程进行详细的阐述，所述基于超声波的丢帧处理方法具体可以包括以下步骤：

在一些实施方式中，移动终端可以包括***负载检测模块，该***负载检测模块主要负责检测***的整体情况，例如，该***负载检测模块可以用于检测移动终端的负载率，其中，移动终端的负载率可以包括移动终端的中央处理器的使用率和/或移动终端的内存的使用率，在此不做限定。在本实施例中，可以实时获取并更新移动终端的负载率，也可以在超声波数据传输给超声波接近计算模块时获取移动终端的负载率，在此不做限定。
其中，在本实施例中，超声波接收模块和超声波接近计算模块分别在移动终端的两个不同的线程中，两者存在数据交换，因此，在超声波数据的从超声波接收模块传输到超声波接近计算模块的过程中，可能存在丢帧的情况，进而影响超声波接近计算模块对于接近检测的计算的结果。因此，在一些实施方式中，移动终端可以获取超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率。其中，移动终端可以获取超声波数据在预设时间段内从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率，例如，可以获取超声波数据在100ms内从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率；可以获取预设帧数的超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率，例如，可以获取100帧超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率；可以获取超声波接收模块接收到的所有超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率，例如，当超声波接收模块接收到1000帧超声波数据，则可以获取100帧超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率等，在此不做限定。
在一些实施方式中，可以先获取移动终端的负载率，再获取超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率；可以先获取超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率，再获取移动终端的负载率；也可以同时获取移动终端的负载率和超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率等，在此不做限定。
步骤S103：基于所述负载率和所述丢帧率确定参数调整方式，并基于所述参数调整方式对所述移动终端的***效能进行调整，以使所述丢帧率小于目标丢帧率。
在一些实施方式中，在获取移动终端的负载率以及超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率后，可以基于负载率和丢帧率确定参数调整方式，并基于该参数调整方式对移动终端的***能效进行调整，以使丢帧率小于目标丢帧率，从而提升接近检测的准确性和用户体验。其中，***效能是指***在规定的条件下满足给定定量特征和服务要求的能力，它是***可用性、可信性及固有能力的综合反映。在本实施例中，该目标丢帧率可以在移动终端出厂时设置，也可以在移动终端出厂时初步设置并在使用过程中更新设置，例如，在移动终端使用过程中，可以根据移动终端所处的环境不同确定不同的目标丢帧率。其中，该目标丢帧率可以设置为5％、6％等，在此不做限定。
在一些实施方式中，移动终端调整的参数可以包括时钟频率和/或带宽，作为一种方式，移动终端可以通过***提供的API接口，对时钟频率和/或带宽进行调整。其中，时钟频率和带宽可以影响移动终端的数据传输率，时钟频率和带宽越大，则数据传输率越高，相应地，移动终端的***效能越高，***的丢帧率越小；而时钟频率和带宽越小，则数据传输率越低，相应地，移动终端的***效能越低，***的丢帧率越大。
参数调整方式可以包括：提高移动终端的时钟频率和/或带宽、降低移动终端的时钟频率和/或带宽以及保持移动终端的时钟频率和/或带宽等。因此，在本实施例中，可以基于负载率和丢帧率确定参数调整方式为提高移动终端的时钟频率和/或带宽，并通过提高移动终端的时钟频率和/或带宽的方式提高移动终端的***效能，以使丢帧率小于目标丢帧率；可以基于负载率和丢帧率确定参数调整方式为降低移动终端的时钟频率和/或带宽，并通过降低移动终端的时钟频率和/或带宽的方式降低移动终端的***效能，在使丢帧率小于目标丢帧率的情况下降低移动终端的功能；可以基于负载率和丢帧率确定参数调整方式为保持移动终端的时钟频率和/或带宽不变，并通过保持移动终端的时钟频率和/或带宽不变的方式保持移动终端的***效能不变，使丢帧率小于目标丢帧率。

在一些实施方式中，移动终端在完成对超声波接收模块接收到的多帧超声波数据的标签添加后，可以将携带有多个标签的多帧超声波数据传输给超声波接近计算模块。
步骤S203：获取所述超声波接近计算模块接收到的标签的数量。
在本实施例中，超声波接近计算模块接收到的每帧超声波数据均携带有一个标签，因此，超声波接近计算模块接收到的标签的数量可以表征超声波接近计算模块接收到的超声波数据的帧数，例如，若超声波接近计算模块接收到960个标签，则可以表征超声波接近计算模块接收到的超声波数据的帧数为960帧。因此，在一些实施方式中，在超声波接收模块完成携带有多个标签的多帧超声波数据的传输后，可以获取超声波接近计算模块接收到的标签的数量。
步骤S204：基于所述超声波接近计算模块接收到的标签的数量和所述多个标签对应的数量，计算所述超声波数据从所述超声波接收模块到所述超声波接近计算模块的传输过程中的丢帧率。
在一些实施方式中，移动终端在获得超声波接近计算模块接收到的标签的数量后，可以基于超声波接近计算模块接收到的标签的数量和多个标签对应的数量，计算超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率。例如，若超声波接收模块连续接收到的超声波数据的帧数为1000帧，那么，移动终端针对1000帧超声波数据添加的标签的数量为1000个，若超声波接近计算模块接收到的标签的数量为960个时，那么，可以确定超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率＝(1000-960)/1000＝4％。
步骤S205：获取所述移动终端的中央处理器的使用率以及所述移动终端的内存的使用率。
在一些实施方式中，移动终端可以检测中央处理器的使用情况，以获得中央处理器的剩余资源。例如，移动终端的操作***为Android***时，可以通过Android***中的ProcessStats类，获取***的使用情况及进程时间。其具体实现原理是读取/proc目录下的文件，***运行 时，内核会去更新/proc目录下的文件，将PID的运行情况写入相应的文件中，根据上述运行情况即可获取到中央处理器的剩余资源，其中，中央处理器的剩余资源可以包括中央处理器的剩余使用率，从而基于中央处理器的剩余使用率获取中央处理器的使用率。
在一些实施方式中，移动终端可以检测内存的使用情况，以获得移动终端的内存的剩余资源。例如，移动终端的操作***为Android***时，可以通过读取文件"/proc/meminfo"的信息获取移动终端的内存的总量，而通过ActivityManager.getMemoryInfo(ActivityManager.MemoryInfo)方法可以获取移动终端的内存当前的可用内存量。具体地，"/proc/meminfo"文件记录了android移动终端的一些内存信息，在命令行窗口里输入"adb shell"，进入shell环境，输入"cat/proc/meminfo"即可在命令行里显示meminfo文件的内容，从而获得内存信息。可以理解的，基于上述方式获得移动终端的内存的总量和当前可用的内存量后，可以计算获得移动终端的内存的使用率。
步骤S206：基于所述中央处理器的使用率和所述内存的使用率，获得所述移动终端的负载率。
在本实施例中，移动终端在获取中央处理器的使用率和内存的使用率之后，可以基于中央处理器的使用率和内存的使用率，获得移动终端的负载率。其中，移动终端的负载率与中央处理器的使用率成正相关且与内存的使用率成正相关。
其中，步骤S203-步骤S204可以设置于步骤S205-步骤S206之前、步骤S203-步骤S204可以设置于步骤S205-步骤S206之后、步骤S203-步骤S204也可以设置于与步骤S205-步骤S206同步，在此不做限定。
步骤S207：当所述负载率小于负载率阈值且所述丢帧率大于第一丢帧率阈值时，确定所述参数调整方式为提高所述移动终端的时钟频率和/或带宽。
在一些实施方式中，移动终端可以预先设置有负载率阈值，该负载率阈值可以用于作为获取的移动终端的负载率的判断依据，因此，在本实施例中，在获得移动终端的负载率后，可以将移动终端的负载率和负载率阈值进行比较，以判断负载率和负载率阈值之间的关系。在一些实施方式中，移动终端可以预先设置并存储有第一丢帧率阈值，该第一丢帧率阈值用于作为获取的超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率的判断依据，因此，在本实施例中，在获得超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率，可以将丢帧率与第一丢帧率阈值进行比较，以判断丢帧率和第一丢帧率阈值之间的关系。例如，该负载率阈值可以为80％，该第一丢帧率阈值可以为5％。
在本实施例中，当判断结果表征负载率小于负载率阈值且丢帧率大于第一丢帧率阈值时，表征移动终端的负载率较低而丢帧率较高，即移动终端还可以承担更多的负载，因此，可以将参数调整方式确定为提高移动终端的时钟频率和/或带宽，以提高移动终端的***效能、降低移动终端的丢帧率，提升接近检测的准确率。当判断结果表征负载率不小于负载率阈值且丢帧率大于第一丢帧率阈值时，表征移动终端的负载率较高且丢帧率较高，而如果要通过提高移动终端的时钟频率和/或带宽来降低移动终端的丢帧率，则会增加移动终端的负载率，在移动终端本身的负载率较高的情况下，可能会造成移动终端卡死的问题，因此，作为一种方 式，移动终端可以发出提示信息，该提示信息用于提示用户对移动终端的运行做出调整，以降低移动终端的负载率。
步骤S208：当所述负载率小于所述负载率阈值且所述丢帧率小于第二丢帧率阈值时，确定所述参数调整方式为降低所述移动终端的时钟频率和/或带宽，其中，所述第二丢帧率阈值小于所述第一丢帧率阈值。
在一些实施方式中，移动终端可以预先设置有负载率阈值，该负载率阈值可以用于作为获取的移动终端的负载率的判断依据，因此，在本实施例中，在获得移动终端的负载率后，可以将移动终端的负载率和负载率阈值进行比较，以判断负载率和负载率阈值之间的关系。在一些实施方式中，移动终端可以预先设置并存储有第二丢帧率阈值，该第二丢帧率阈值用于作为获取的超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率的判断依据，因此，在本实施例中，在获得超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率，可以将丢帧率与第二丢帧率阈值进行比较，以判断丢帧率和第二丢帧率阈值之间的关系。其中，该第二丢帧率小于第一丢帧率，例如，该负载率阈值可以为90％，该第二丢帧率阈值可以为1％。
在本实施例中，当判断结果表征负载率小于负载率阈值且丢帧率小于第二丢帧率阈值时，表征移动终端的负载率较低且丢帧率较低，甚至没有丢帧，即可以适当降低移动终端的***效能、节省移动终端的***资源、降低移动终端的功耗，因此，可以将参数调整方式确定为降低移动终端的时钟频率和/或带宽，以降低移动终端的***效能、降低移动终端的功耗。当判断结果表征负载率不小于负载率阈值且丢帧率小于第二丢帧率阈值时，表征移动终端的负载率较高且丢帧率较低，而如果要降低***效能，则会造成移动终端的负载快速增加，可能导致移动终端的负载较高，造成移动终端卡死的问题，因此，在判断结果表征负载率不小于负载率阈值且丢帧率小于第二丢帧率阈值时，可以不进行处理。
步骤S209：当所述负载率小于所述负载率阈值以及所述丢帧率大于所述第二丢帧率阈值且小于所述第一丢帧率阈值时，确定所述参数调整方式为保持所述移动终端的时钟频率/或带宽不变。
在一些实施方式中，移动终端可以预先设置有负载率阈值，该负载率阈值可以用于作为获取的移动终端的负载率的判断依据，因此，在本实施例中，在获得移动终端的负载率后，可以将移动终端的负载率和负载率阈值进行比较，以判断负载率和负载率阈值之间的关系。在一些实施方式中，移动终端可以预先设置并存储有第一丢帧率阈值和第二丢帧率阈值，该第一丢帧率阈值和第二丢帧率阈值用于作为获取的超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率的判断依据，因此，在本实施例中，在获得超声波数据从超声波接收模块到超声波接近计算模块的传输过程中的丢帧率，可以将丢帧率与第一丢帧率阈值和第二丢帧率阈值进行比较，以判断丢帧率和第一丢帧率阈值和第二丢帧率阈值之间的关系。其中，该第二丢帧率小于第一丢帧率，例如，该负载率阈值可以为90％，该第一丢帧率阈值可以为5％，第二丢帧率阈值可以为1％。
在本实施例中，当判断结果表征负载率小于负载率阈值、丢帧率大于第二丢帧率阈值且 小于第一丢帧率阈值时，表征移动终端的负载率较低且丢帧率对于接近检测的准确率的影响较小，即可以保持移动终端的***效能不变，因此，可以将参数调整方式确定为保持移动终端的时钟频率和/或带宽不变，以保证移动终端的丢帧率和功耗均在预设范围内。当判断结果表征负载率不小于负载率阈值、丢帧率大于第二丢帧率阈值且小于第一丢帧率阈值时，表征移动终端的负载率较高且丢帧率较低，而如果要降低***效能，则会造成移动终端的负载快速增加，可能导致移动终端的负载较高，造成移动终端卡死的问题，因此，在判断结果表征负载率不小于负载率阈值且丢帧率大于第二丢帧率阈值且小于第一丢帧率阈值时，可以不进行处理。

在一些实施方式中，当移动终端通过超声波接收装置接收到超声波信号后，可以获取该超声波信号在传输过程中的属性值，并基于该属性值计算该超声波信号在传输过程中的多普勒效应面积差和多普勒效应面积和。其中，传输过程中可以包括超声波信号发送的过程以及超声波信号接收的过程，该属性值可以包括超声波发送装置发送的超声波信号的发送频率、发送幅值、发送时间等，超声波接收装置所接收的超声波信号的频率变化范围、接收幅值、接收时间等，在此不做限定。
步骤S212：根据所述多普勒效应面积差和所述多普勒效应面积和，确定所述移动终端与所述物体的相对运动状态。
在一些实施方式中，移动终端在获取多普勒效应面积差和多普勒效应面积和后，可以基于该多普勒效应面积差和多普勒效应面积和，获取移动终端与物体的相对运动状态，并根据移动终端与物体的相对运动状态控制移动终端的显示屏处于亮屏状态或息屏状态，从而提升显示屏的状态控制的准确率和稳定性，有效降低移动终端的功耗以及降低显示屏在靠近人脸时处于亮屏状态对人脸造成的辐射。
