具体实施方式
为使本申请的目的、技术方案、及优点更加清楚明白，以下参照附图并举实施例，对本申请进一步详细说明。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参见图1，其示出了本申请部分实施例中提供的音量调节方法所涉及的实施环境的示意图。该实施环境可以为室内环境也可以为室外环境，通常为室内环境。该实施环境可以包括：终端01和至少一个用户02。其中，终端01可以具有音视频播放功能，本申请实施例中，音视频包括音频和视频中的至少一种，终端01可以为音箱、智能手机、电脑、多媒体播放器、电子阅读器、可穿戴式设备等。终端01和至少一个用户02的距离可以动态改变。例如，该实施环境可以是在客厅的一端放置有一个音箱，用户开始位于客厅另一端的沙发上，用户可以通过设置在音箱上的按钮或者使用相应的遥控器控制音箱，进行音频播放，同时在音频播放的过程中，用户的位置可能会产生变化，比如，用户在音频播放的过程中，可能会离开当前位置去喝水或者运动，这样就会使用户和音箱的距离发生改变。又例如，该实施环境可以是在酒店大厅的中央放置有一个音箱，酒店内的人员作为用户分散于音箱周围，任一用户可以通过设置在音箱上的按钮或者使用相应的遥控器控制音箱，进行音频播放，同时在音频播放的过程中，用户的位置可能会产生变化，比如，保安的巡逻或者清洁工的打扫，这样就会使用户和音箱的距离发生改变。
图2是根据一示意性实施例示出的一种音量调节方法的方法流程图，该音量调节方法可以用于控制终端01的音量调节，该音量调节方法可以由图1所示实施环境中的终端01来执行。参见图2，该方法流程可以包括如下几个步骤：
步骤201、在终端播放音视频的过程中，确定终端与目标物体的目标距离。
在本申请实施例中，音视频包括音频和视频中的至少一种。
步骤202、根据目标距离确定目标音量。
步骤203、将终端播放的音视频的音量调节至目标音量。
综上所述，本申请实施例提供的音量调节方法，根据终端与目标物体的目标距离来确定目标音量，并将终端播放的音视频的音量调节至目标音量，实现了终端音视频音量的自动调节，无需用户手动调节终端的音量，简化了调节音量的操作过程，使得音量调节操作更加便捷。
图3是根据一示意性实施例示出的另一种音量调节方法的方法流程图，该音量调节方法可以由图1所示实施环境中的音视频播放终端01来执行。参见图3该方法流程可以包括如下几个步骤：
步骤301、检测终端所在的预设范围内是否存在移动物体。
由于本申请实施例中，终端的音量需要根据终端与用户的距离来调节，以满足用户的听觉舒适度，而通常情况下，在终端固定时，终端与用户的距离改变是基于用户的运动，因此，在终端满足预设触发条件时，会检测终端所在的预设范围内是否存在移动物体，该预设触发条件可以为终端上电，也可以为终端开始播放音视频。终端可以在这些移动物体中再确定目标物体，将该目标物体默认为用户。实际应用中，该目标物体可以是人体，也可以是猫、狗等能够移动的宠物，本申请实施例对此不做限定。
可选的，如图4所示，该步骤301可以包括：
步骤3011、判断终端可检测范围内是否存在移动物体。
示例的，判断终端可检测范围内是否存在移动物体的过程可以包括如下步骤：
步骤3011a、周期性获取终端可检测范围内的图像。
示例的，可以通过终端自带的图像获取模块或者是和终端连接的图像获取模块来获得终端可检测范围内的图像，该图像获取模块可以为摄像头，实际应用中，摄像头获取的图像的大小通常为：640×480、1024×768、1600×1200或者2048×1536。具体的，针对不同的摄像头，获取的图像的大小不同。在成像的两组数字中，前者为图片宽度，后者为图片的高度。获取的图像的长宽比一般为4：3。该终端可检测范围内的图像指的是终端能够检测到的范围内中的图像，例如，可以为图像获取模块的可拍摄范围内的图像。其中，获取图像的周期可以为固定周期，例如1秒或0.5秒，也可以为可变周期，例如，两个相邻的获取周期通过不同触发方式触发，或者符合预设规律，使得两个相邻的获取周期的时长不同。
步骤3011b、比较当前周期获取的图像与上一周期获取的图像。
以获取周期为固定周期，且为0.5秒为例，将当前周期获取的图像与0.5秒前获取的上一周期的图像进行比较，确定两帧图像是否存在位置变化的物体，在当前周期获取的图像与上一周期获取的图像中存在位置变化的物体时，则执行步骤3011c，在当前周期获取的图像与上一周期获取的图像中不存在位置变化的物体时，则执行步骤3011a。
需要说明的是，终端比较的图像通常是从同一角度获取的图像，如果终端能够移动，则终端对不同角度获取的图像通常不进行比较。
步骤3011c、在当前周期获取的图像与上一周期获取的图像中存在位置变化的物体时，确定终端可检测范围内存在移动物体，且移动物体为存在位置变化的物体。
例如，终端在同一角度拍摄了两幅图像，该两幅图像中形状相同物体产生了位置变化，则终端确定该物体为存在位置变化的物体。
需要说明的是，本申请实施例中的位置变化可以为水平方向的位置变化，也可以为竖直方向的位置变化。
实际应用中，移动物体的数量可以为多个，在将当前周期获取的图像与上一周期获取的图像进行对比时，可以将所有的位置存在变化的物体确定为移动物体。
本申请实施例中，还可以通过其他方式判断终端可检测范围内是否存在 移动物体，例如，采用超声波来判断终端可检测范围内是否存在移动物体。其中，该超声波是一种频率高于20000赫兹的声波，它的方向性好，穿透能力强，易于获得较集中的声能，经常被应用于测距、测速等方面。示例的，终端上设置有超声波发生器和超声波接收器，终端通过该超声波发生器周期性发射超声波信号，其中，发射超声波信号的周期可以为固定周期，例如1秒或2秒，也可以为可变周期，例如，两个相邻的发射周期通过不同触发方式触发，或者符合预设规律，使得两个相邻的发射周期的时长不同；终端通过超声波接收器接收返回的超声波反射信号；终端比较当前周期接收到的超声波反射信号和上一周期接收到的超声波反射信号，判断是否存在移动物体；如果当前周期接收到的超声波反射信号与上一周期接收到的超声波反射信号不同，则判断存在移动物体；如果当前周期接收到的超声波反射信号与上一周期接收到的超声波反射信号相同，则判断不存在移动物体。
以发射超声波信号的周期为固定周期，且为1秒为例，将终端当前周期接收到的超声波反射信号与1秒前接收到的超声波反射信号进行对比，如果该两个超声波反射信号的波形产生了变化，则判断存在移动物体。如果该两个超声波反射信号的波形没有产生变化，则判断不存在移动物体。
需要说明的是，终端比较的超声波信号是从同一角度发射和接收的信号，如果终端能够移动，则终端对不同角度发射和接收的信号通常不进行比较。
步骤3012、在终端可检测范围内存在移动物体时，获取包括移动物体的图像。
示例的，可以通过终端自带的图像获取模块或者是和终端连接的图像获取模块来获得包括移动物体的图像，该图像获取模块可以为摄像头，该包括移动物体的图像可以为摄像头的获取的终端可检测范围内的图像，且该终端可检测范围内的图像内包括移动物体。
步骤3013、根据包括移动物体的图像，确定移动物体是否处于终端所在的预设范围内。
具体的，根据包括移动物体的图像，确定移动物体是否处于终端所在的预设范围内的方法，可以包括如下步骤：
步骤3013a、检测包括移动物体的图像中，移动物体与预设大小的参考物 的相似度相关值是否小于预设相关值阈值。
其中，该相似度相关值和相似度负相关，也就是，当移动物体与预设大小的参考物的相似度相关值越小的时候，移动物体与预设大小的参考物的相似度越高，两者的相似主要表现为大小的相似。
对于预设相关值阈值本申请实施例不做具体限定，可以根据实际情况来设置预设相关值阈值，实际应用中，该预设相关值阈值可以设置为10。
可选的，将包括移动物体的图像确定为目标图像，在检测目标图像中移动物体与预设大小的参考物的相似度相关值是否小于预设相关值阈值前，可以先在该目标图像中建立图像坐标系，在该图像坐标系中计算出移动物体与该参考物的相似度相关值，示例的，假设该图像坐标系的原点为该目标图像的左上角，在该坐标系中，x轴的正方向为沿水平方向向右的方向，y轴的正方向为沿竖直方向向下的方向，相应的，移动物体与该参考物的相似度相关值计算公式可以为：
Figure PCTCN2017105353-appb-000001
i∈(0，image_width-N)，j∈(0，image_height-M)；
其中，M为该参考物的高度(单位为1个像素)，N为该参考物的宽度(单位为1个像素)，M×N代表该参考物大小的像素的矩阵，target(i，j)代表该参考物在坐标为(i，j)的像素点的亮度分量，current(ii，jj)代表目标图像的整体亮度分量。image_width代表目标图像的宽度(单位为1个像素)，image_height代表目标图像的高度(单位为1个像素)。DiffAvgpixelval代表移动物体与该参考物的相似度相关值，DiffAvgpixelval和移动物体与该参考物的相似度呈负相关，即DiffAvgpixelval的值越小，表示移动物体与该参考物的相似度越高。ABS(*)表示对括号中内容求绝对值。
将移动物体与该参考物的相似度相关值和预设相关值阈值进行对比，如果移动物体与该参考物的相似度相关值小于预设相关值阈值时，则执行步骤3013b，示例的，如图5所示，假设图5中终端获取的图像中移动物体L1与该参考物的相似度相关值小于预设相关值阈值，此时则可以执行步骤3013b；如果移动物体与该参考物的相似度相关值不小于预设相关值阈值时，此时可 以执行步骤3013c，然后返回步骤301继续检测，示例的，如图6所示，假设图6中终端获取的图像中移动物体L2与该参考物的相似度相关值大于预设相关值阈值时，此时则可以执行步骤301。
步骤3013b、在移动物体与预设大小的参考物的相似度相关值小于预设相关值阈值时，确定移动物体处于终端所在的预设范围内。
步骤3013c、在移动物体与预设大小的参考物的相似度相关值不小于预设相关值阈值时，确定移动物体不处于终端所在的预设范围内。
步骤302、在终端所在的预设范围内存在移动物体时，确定移动物体的数量。
实际应用中，终端所在的预设范围内的移动物体可能有多个，因此需要确定移动物体的数量。
步骤303、在移动物体的数量为1时，将移动物体确定为目标物体。
如果终端范围内只有一个移动物体时，可以将该移动物体确定为目标物体。
步骤304、在移动物体的数量为至少两个时，在至少两个移动物体中选择一个移动物体作为目标物体。
本申请实施例中，在至少两个移动物体中选择目标物体的选择方式可以有多种，示例的，该选择方式可以包括以下方式中的一种或多种，当该选择方式包括以下方式中的多种时，可以为多种方式中的每种方式设定优先级，按照相应的优先级来执行选择过程：
第一种方式、在该至少两个移动物体中选择距离终端最近的物体；第二种方式、在该至少两个移动物体中选择终端的发声方向朝向的物体；第三种方式、在该至少两个移动物体中选择正面(例如人脸)朝向终端的物体。
假设在放置有终端的室内，有小黑和小白两人。其中，小黑位于距离终端5米的地方，小白位于距离终端6米的地方，终端的发声方向背向小黑，朝向小白，小黑的正脸朝向终端，小白背对终端。如果采用上述第一种方式进行选择，则选择小黑作为目标物体；如果采用上述第二种方式进行选择，则选择小白作为目标物体；如果采用上述第三种方式进行选择，则选择小黑作为目标物体。因此，在相同的情况下，采用不同的选择方式，选择出的目 标物体可能不相同。
该目标物体可以是人体，也可以是猫、狗等能够移动的宠物，但是实际应用中，终端也可能将一些可移动的机器识别为目标物体，例如扫地机器人或无人机，但是针对这样的目标物体进行音量调节失去了改善用户体验的初衷，因此，终端上可以安装活体识别模块，在确定目标物体后，对该目标物体进行活体识别，如果该目标物体为活体，则针对目标物体进行音量调节，如果该目标物体不是活体，可以将该目标物体排除后重新执行上述步骤301至304，直至找到活体的目标物体。
步骤305、在终端播放音视频的过程中，确定终端与目标物体的目标距离。
其中，该目标距离为目标物体的中心位置与终端的距离。对于确定终端与目标物体的目标距离的方法，本申请实施例可以通过以下三种方式来实现：
第一种可实现方式，利用双目立体视频算法计算终端与目标物体的目标距离，具体过程可以包括：
步骤A1、采集目标物体的双目立体视频图像。
步骤B1、对双目立体视频图像进行基于图像分割立体匹配的视差估计。
步骤C1、对图像分割立体匹配得到的视差图像进行一致性检查，采用自适应匹配删除不可靠的匹配，减小深度图像的误匹配。
步骤D1、根据视差与深度之间的关系，把视差图像转为深度图像。
步骤E1、采用多边滤波器对该深度图像进行矫正优化。
步骤F1、输出深度图像，得到双目立体视频深度信息。
其中，目标距离D＝Depth(x，y)，Depth(x，y)表示目标物体的深度信息，(x，y)为目标物体的中心在预设坐标系的坐标值。
第二种可实现方式，采用红外测距方式或激光测距方式确定目标距离，具体过程可以包括：
步骤A2、在终端所在处向目标物体发射一束目标光线，该目标光线为激光或红外光。
步骤B2、接收目标物体反射回来的目标光线。
步骤C2、获取该目标光线的往返时间。
步骤D2、根据该往返时间计算目标物体与终端之间的距离。
其中，目标物体与终端之间的距离可以通过公式D＝ct/2来计算，D代表目标距离，c代表目标光线的光速，t代表获取的目标光线的往返时间。
第三种可实现方式，根据相对位置定位方式确定目标距离。
其中，根据相对位置定位方式确定目标距离的方式是一种根据物体相对于参照对象的位移变化来定位的方式。具体可以包括全球定位系统(英文：Global Position System；简称：GPS)定位或者无线保真(英文：Wireless-Fidelity；简称：WIFI)定位等方式。本申请实施例对此不做赘述。
步骤306、根据目标距离确定目标音量。
本申请实施例中的目标音量为使得目标物体在所在位置感到舒适的音量。例如，当目标物体为人时，由于人耳觉得舒适的音量一般为60分贝至75分贝之间，因此可以将目标音量设置为使得人感受到的音量为60分贝至75分贝之间的音量。
对于根据目标距离确定目标音量的方法，本申请实施例可以通过以下两种方式来实现：
第一种可实现方式为：查询预设的距离与音量对应关系，得到目标距离对应的目标音量。
该预设的距离与音量的对应关系可以为预设的距离、位置与音量的关联表，具体的，可以在终端出厂之前，通过实验采集对应的距离、位置和音量的数据，其中，进行该采集实验的实验环境可以为一般的标准环境，可以在面积为50平方米的房间内进行该采集实验，在该房间的长度方向的一端设置一个音箱，设置人作为目标物体，设置目标音量为60分贝进行实验，不断调节目标物体与音箱的距离、位置，记录下在该距离、位置下能使该目标物体感受到的音量为60分贝的对应音量，例如，在目标物体面朝音箱的发声方向，且距离音箱2米时，记录下对应的目标音量；在目标物体面朝音箱的发声方向，且距离音箱3米时，记录下对应的目标音量；在目标物体背对音箱的发声方向，且距离音箱2米时，记录下对应的目标音量；在目标物体背对音箱的发声方向，且距离音箱3米时，记录下对应的目标音量；通过多次调整目标物体与音箱的距离、位置，记录多组数据。根据采集到的数据得出预设的距离、位置与音量的关联表，并将该关联表存储在终端的存储模块。
在获取了目标距离后，可以通过查表的方式，得出目标距离对应的目标音量。
第二种可实现方式为：获取目标物体的位置，根据目标物体的位置和目标距离，采用预设关联算法计算得到目标音量。
具体的，可以在终端出厂之前，通过实验采集对应的距离、位置和音量的数据，其中，进行该采集实验的实验环境可以为一般的标准环境，可以在面积为50平方米的房间内进行该采集实验，在该房间的长度方向的一端设置一个音箱，设置人作为目标物体，设置目标音量为60分贝进行实验，不断调节目标物体与音箱的距离、位置，记录下在该距离、位置下能使该目标物体感受到的音量为60分贝的对应音量，例如，在目标物体面朝音箱的发声方向，且距离音箱2米时，记录下对应的目标音量；在目标物体面朝音箱的发声方向，且距离音箱3米时，记录下对应的目标音量；在目标物体背对音箱的发声方向，且距离音箱2米时，记录下对应的目标音量；在目标物体背对音箱的发声方向，且距离音箱3米时，记录下对应的目标音量；通过多次调整目标物体与音箱的距离、位置，记录多组数据。根据采集到的数据得出预设的距离、位置与音量的预设关联算法，并将该关联算法存储在终端的存储模块。其中，该预设关联算法可以为：V＝f(D，T)，V为目标音量，D为目标距离，T为目标物体的位置。
在获取了目标距离后，可以将目标物体的位置和目标距离带入该预设关联算法中，计算出目标距离对应的目标音量。
需要说明的是，针对预设关联算法，需要为终端设置一个预设坐标系，则在该算法建立时，采集的位置是基于该坐标系的，而终端在采集目标物体的位置也是基于该预设坐标系的，这样才能保证计算目标音量的准确性。
步骤307、将终端播放的音视频的音量调节至目标音量。
对于具体的调节方法，本申请实施例不做限定，可以参考相关技术来实现。本步骤中的目标音量即为步骤306中根据目标距离得出的目标音量。
步骤308、调节终端的发声方向，使终端的发声方向朝向目标物体。
对于具体的发声方向调节方法，本申请实施例不做限定，可以参考相关技术来实现。示例的，如图7-1和图7-2所示，假设终端为音箱，该音箱包括 发声结构01和移动结构02，移动结构02可以使发声结构01移动，从而使其发声方向调整。例如，如图7-1所示，该移动结构02包括底座021，以及设置在该底座021上能够旋转的转轴022，发声结构01与该转轴022固定连接，在该转轴022的带动下旋转，使其发声方向调整。可选的，底座021中可以设置有空腔，空腔中设置有驱动结构，该驱动结构可以为微型电机，用以驱动转轴转动，实际应用中，该转轴也可以由用户手动调节，本申请实施例对此不作限定。
如图7-2所示，移动结构02的上端和发声结构01的下端可以安装有磁性结构(图7-2未绘出)，通过调整两者之间的磁力，可以使得发声结构01悬浮于移动结构02上方，且发声结构01能够旋转，从而调整发声方向。
本申请实施例中，通过调节终端的发声方向，使终端的发声方向朝向目标物体，可以使得目标物体获得更好地视听音效。
实际应用中，本申请实施例还可以通过其他方式确定终端与目标物体的目标距离，例如，在检测到终端的可检测范围内存在至少一个移动物体(检测方法可以参考上述步骤3011)时，确定该终端与各个移动物体的距离，判断该终端与各个移动物体的距离中是否存在小于预设距离阈值的距离，具体的预设距离阈值可以根据实际情况来设置，例如，该预设距离阈值可以设置为3米。当该终端与各个移动物体的距离中存在小于预设距离阈值的距离时，将对应距离小于该预设距离阈值的物体确定为目标物体，并将终端与该目标物体的距离确定为目标距离。
值得说明的是，本申请实施例提供的音量调节方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行相应增减，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本申请的保护范围之内，因此不再赘述。
综上所述，本申请实施例提供的音量调节方法，根据终端与目标物体的目标距离来确定目标音量，并将终端播放的音视频的音量调节至目标音量，实现了终端音视频音量的自动调节，无需用户手动调节终端的音量，简化了调节音量的操作过程，使得音量调节操作更加便捷。
