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。
图1A是根据一示例性实施例示出的一种角度测量方法的流程图，如图1A所示，角度测量方法可以但不限于应用于包括摄像头的终端中，包括以下步骤。
在步骤101中，在终端的显示界面中显示水平基准线和测量线以及摄像头当前拍摄的物体，该测量线和水平基准线确定的平面与显示界面平行且该测量线与显示界面相对静止。
水平基准线是用于指示水平方向的基准线，其始终保持水平。测量线用于测量物体与水平面之间的角度，测量线随着终端进行转动，也就是说，测量线与显示界面相对静止。
图1B是根据本实施例示出的第一种水平基准线和测量线的示意图，图1B中测量线与终端的长平行。由于终端的长与水平面平行且测量线平行于终端的长，因此，测量线与水平基准线平行。其中，本实施例将终端在水平方向的边确定为终端的长，比如，图1B(1)是诸如手机之类的阅读方向为竖向的显示界面，图1B(2)是诸如平板电脑之类的阅读方向为横向的显示界面。图1B中，实线表示的是水平基准线，虚线表示的是测量线，虚实线表示的是水平面，下文不再赘述。
图1C是根据本实施例示出的第二种水平基准线和测量线的示意图。由于终端的长与水平面之间存在角度且测量线平行于终端的长，因此，测量线与水平基准线之间存在角度。
在步骤102中，在转动终端使物体的边缘与测量线平行的过程中，计算测量线与水平基准线之间的角度。
由于测量线在显示界面相对静止且水平基准线保持水平，因此，在转动终端的过程中，测量线与水平基准线之前会形成夹角，可以测量该夹角。
在步骤103中，将边缘与测量线平行时得到的角度确定为物体与水平面之间的角度。
当测量线与物体的边缘平行时，测量线与水平基准线之间的角度即为物体与水平面之间的角度，因此，终端可以将物体的边缘与测量线平行时计算得到的角度确定为物体与水平面之间的角度。
综上所述，本公开提供的角度测量方法，通过在终端的显示界面中显示水平基准线和测量线以及摄像头当前拍摄的物体，该测量线和水平基准线确定的平面与显示界面平行且该测量线在显示界面相对静止；在转动终端使物体的边缘与测量线平行的过程中，计算测量线与水平基准线之间的角度；将边缘与测量线平行时得到的角度确定为物体与水平面之间的角度，由于测量线与实景中的物体边缘平行时，终端可以测量物体与水平面之间的角度，解决了终端的角度测量功能单一的问题，达到了扩展终端的角度测量功能的效果。
图2A是根据另一示例性实施例示出的一种角度测量方法的流程图，本实施例使用水平仪APP来测量终端与水平面之间的角度，如图2A所示，角度测量方法可以应用于包括摄像头和水平仪APP的终端中，包括如下步骤。
在步骤201中，检测终端是否处于倾斜状态；若检测出终端处于倾斜状态，则启动摄像头，执行步骤202。
若终端与水平面之间不存在夹角，则终端所要测量的物体在水平面上，此时物体与水平面之间的角度是0°，终端不需要进行角度测量。为了避免终端不需要测量角度而触发角度测量流程所造成的资源浪费，可以检测终端是否处于倾斜状态。若终端处于倾斜状态，则启动角度测量流程，通过启动终端中预先安装的摄像头以进行角度测量；若终端处于水平状态，则不启动角度测量流程。
其中，检测终端是否处于倾斜状态，包括：
1)测量终端与水平面之间的倾斜角度；
2)检测倾斜角度是否属于预设的角度范围；
3)若检测出倾斜角度属于角度范围，则确定终端处于倾斜状态。
在测量终端是否处于倾斜状态时，终端可以启动终端中预先安装的水平仪APP，通过水平仪APP测量终端与水平面之间的倾斜角度。其中，倾斜角度是指终端的显示界面向上且与水平面平行时，绕终端的底边或侧边所在方向旋转到当前姿态时的旋转角度。
水平仪APP测量终端的倾斜角度可以依据各种成熟技术，此处不作赘述。
终端在获取到水平仪APP测得的倾斜角度后，还可以比较该倾斜角度与预设的角度范围。若该倾斜角度属于角度范围，则确定终端处于倾斜状态；若该倾斜角度不属于角度范围，则确定终端处于水平状态。其中，角度范围可以进行设置和修改。比如，角度范围 是(45°，135°)，或，角度范围修改为(5°，175°)等等。
在步骤202中，在终端的显示界面中显示水平基准线和测量线以及摄像头当前拍摄的物体，该测量线和水平基准线确定的平面与显示界面平行且该测量线与显示界面相对静止。
水平基准线是用于指示水平方向的基准线，其始终保持水平。测量线用于测量物体与水平面之间的角度，其与显示界面相对静止。其中，测量线可以为至少一条，本实施例以一条测量线为例进行说明。
测量线可以与终端的长或宽平行。请参考图1B所示的第一种水平基准线和测量线的示意图和图1C所示的第二种水平基准线和测量线的示意图。或，测量线也可以不与终端的长和宽平行，请参考图2B所示的第三种水平基准线和测量线的示意图。由于终端的长与水平面平行且测量线不平行于终端的长，因此，测量线与水平基准线不平行。
当摄像头处于开启状态时，摄像头实时拍摄物体，并将拍摄到的物体显示在显示界面中。
在步骤203中，在转动终端使物体的边缘与测量线平行的过程中，计算测量线与水平基准线之间的角度。
由于测量线在显示界面相对静止且水平基准线保持水平，因此，在转动终端的过程中，测量线与水平基准线之前会形成夹角，水平仪APP可以测量该夹角。
其中，在转动终端使物体的边缘与测量线平行的过程中，计算测量线与水平基准线之间的角度，包括：
1)若初始时刻测量线与水平基准线平行或重合，则测量测量线基于水平基准线的转动角度，将转动角度确定为测量线与水平基准线之间的角度；
2)若初始时刻测量线与水平基准线之间存在初始角度，则测量测量线基于水平基准线的转动角度，计算转动角度减去初始角度的角度差值，将角度差值确定为测量线与水平基准线之间的角度。
计算角度时，若初始时刻测量线与水平基准线平行或重合，则测量线基于水平基准线转动的角度即为终端基于水平面转动的角度，水平仪APP可以测量终端基于水平面转动的角度，并将该角度确定为测量线与水平基准线之间的角度。若初始时刻测量线与水平基准线之间存在初始角度，则在用户转动终端之前，水平仪APP预先获取终端与水平面之间的初始角度；用户转动终端，在摄像头拍摄的物体的边缘与显示界面中的测量线平行时停止转动终端，水平仪APP测量终端与水平面之间的转动角度，将转动角度减去初始角度，得到测量线与水平基准线之间的角度。
可选的，为了使用户明确转动角度，在转动终端的过程中，水平仪APP可以每隔预定时间通过上述测量角度，并将测得的角度显示在显示界面中。
其中，用户在确定物体的边缘与测量线平行时，可以将终端在该位置保持预定时长，当终端检测到终端在某一位置保持预定时长后，确定物体边缘与测量线平行，触发水平仪 APP计算角度；或，用户在确定物体的边缘与测量线平行时，可以向终端发送触发信号，当终端接收到触发信号后，确定物体边缘与测量线平行，触发水平仪APP计算角度。其中，触发信号可以是点击显示界面提供的按钮，或，在显示界面中执行预定手势的操作等等，本实施例不作限定。
在步骤204中，将边缘与测量线平行时得到的角度确定为物体与水平面之间的角度。
当测量线与物体的边缘平行时，测量线与水平基准线之间的角度即为物体与水平面之间的角度，因此，终端可以将物体的边缘与测量线平行时计算得到的角度确定为物体与水平面之间的角度。
为了便于理解，本实施例以终端横向放置为例对角度测量的过程进行说明。图2C是根据本实施例示出的角度测量的应用图，图2C中测量线与终端的长平行且预设角度范围是(10°，170°)。
①在用户转动终端之前，由于终端与水平面之间的角度为0，因此，显示界面中显示测量线211和水平基准线212，测量线211与水平基准线212平行，请参考图2C(1)所示的第一种角度测量的示意图；
②在用户转动终端的过程中，通过水平仪APP测量终端与水平面之间的角度，当测量到终端与水平面之间的角度达到10°，属于角度范围(10°，170°)时，终端启动摄像头，在显示界面中显示测量线211和水平基准线212以及摄像头实时拍摄到的物体，假设摄像头拍摄到桌子213和板214且板214斜靠在桌子213上，请参考图2C(2)所示的第二种角度测量的示意图；
③在用户转动终端使板214的边缘与测量线211平行时，通过水平仪APP计算测量线211与水平基准线212之间的角度为40°，将该角度40°确定为板214与水平面之间的角度，并将该角度40°显示在显示界面中，请参考图2C(3)所示的第三种角度测量的示意图。
需要补充说明的是，终端还可以对两个物体之间的角度进行测量，则该方法，还包括：
1)若摄像头还拍摄到另一物体，则在转动终端使另一物体的边缘与测量线平行的过程中，计算测量线与水平基准线之间的角度；
2)将另一物体的边缘与测量线平行时得到的角度确定为另一物体与水平面之间的角度；
3)计算物体与水平面之间的角度减去另一物体与水平面之间的角度的差值；
4)将该差值的绝对值确定为物体和另一物体之间的角度。
终端在执行步骤201至204获取到物体与水平面之间的角度之前或之后，还可以执行步骤201至204获取到另一物体与水平面之间的角度，计算物体与水平面之间的角度减去另一物体与水平面之间的角度的差值，将该差值的绝对值确定为物体与另一物体之间的角度。
比如，终端第一次执行步骤201至204测得物体与水平面之间的角度是49°，终端第 二次执行步骤201至204测得另一物体与水平面之间的角度是13°，则物体与另一物体之间的角度是36°。
综上所述，本公开提供的角度测量方法，通过在终端的显示界面中显示水平基准线和测量线以及摄像头当前拍摄的物体，该测量线和水平基准线确定的平面与显示界面平行且该测量线与显示界面相对静止；在转动终端使物体的边缘与测量线平行的过程中，计算测量线与水平基准线之间的角度；将边缘与测量线平行时得到的角度确定为物体与水平面之间的角度，由于测量线与实景中的物体边缘平行时，终端可以测量物体与水平面之间的角度，解决了终端的角度测量功能单一的问题，达到了扩展终端的角度测量功能的效果。
另外，通过在检测出终端处于倾斜状态后启动摄像头，可以避免终端测量水平面上的物体与水平面之间的角度时造成的资源浪费，达到了节省终端的资源的效果。
