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方向测量方法的流程图，如图1A所示，方向测量方法可以但不限于应用于包括摄像头和指南针APP的终端中，包括以下步骤。
在步骤101中，当终端运行指南针APP时，启动摄像头，通过该摄像头获取实景。
在运行指南针APP的过程中，终端启动摄像头，通过摄像头对当前的实景进行拍摄。
在步骤102中，根据指南针APP确定摄像头的正对方向。
由于摄像头安装在终端中，而指南针APP可以测量终端的各个方向，因此，指南针APP可以根据测得的终端的各个方向确定摄像头的正对方向。
图1B是根据本实施例示出的摄像头正对方向的示意图，图1B(1)是诸如手机之类的阅读方向为竖向的摄像头正对方向的示意图，图1B(2)是诸如平板电脑之类的阅读方向为横向的摄像头正对方向的示意图。图1B中位于终端背面的小圆点即为摄像头，摄像头的正对方向与终端的正对方向相同，均为由终端前面垂直指向终端背面的方向。
在步骤103中，在实景中显示正对方向。
由于实景正对摄像头，因此，指南针APP测得的摄像头的正对方向即为实景方向，将该正对方向显示在实景中，即可以向用户提供实景方向。
综上所述，本公开提供的方向测量方法，通过当终端运行指南针APP时，启动摄像头，通过摄像头获取实景；根据指南针APP确定摄像头的正对方向；在实景中显示正对方向，可以将摄像头的正对方向作为实景方向直接显示在实景中，解决了终端无法向用户提供现实场景中的方向的问题，达到了扩展终端的方向测量功能的效果。
图2A是根据另一示例性实施例示出的一种方向测量方法的流程图，如图2A所示，方向测量方法可以但不限于应用于包括摄像头和指南针APP的终端中，包括如下步骤。
在步骤201中，当终端运行指南针APP时，检测终端是否处于倾斜状态；若检测出终端处于倾斜状态，则执行步骤202。
本实施例提供的方向测量方法通常应用于实景方向的测量，因此，若终端与水平面之间不存在夹角，摄像头的拍摄角度是垂直于地面的，此时无法测量实景方向。因此，为了避免终端无法测量实景方向而触发方向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，则启动方向测量流程，通过启动终端中预先安装的摄像头以进行方向测量；若终端处于水平状态，则不启动方向测量流程。
其中，检测终端是否处于倾斜状态，包括：
1)通过终端中的方向传感器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方向传感器，通过方向传感器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。
本实施例中，方向传感器可以是陀螺仪和/或加速度传感器。通过方向传感器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。
终端在获取到方向传感器测得的倾斜角度后，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。
需要补充说明的是，当倾斜角度大于预定角度时，终端的指示方向会由终端的正对方向变化为与该正对方向相反的方向，因此，为了保证方向测量的准确性，可以将该预定值设置为角度范围的最大值。
在步骤202中，启动摄像头，通过该摄像头获取实景。
当摄像头处于开启状态时，摄像头实时拍摄实景，并将拍摄到的实景显示在显示界面中。
在步骤203中，根据指南针APP确定摄像头的正对方向。
由于摄像头安装在终端中，而指南针APP可以测量终端的各个方向，因此，指南针APP可以根据测得的终端的各个方向确定摄像头的正对方向。
其中，根据指南针APP确定摄像头的正对方向，包括：
1)确定终端的姿态，以及，通过指南针APP确定终端的各个方向；
2)根据终端的姿态和终端的各个方向确定摄像头的正对方向。
由于终端中预先建立有坐标系，因此，可以通过方向传感器测量终端处于当前姿态时相对于各个轴向的参数值，根据测得的参数值确定终端的姿态。其中，本实施例以阅读方向为竖向的终端通常采用的坐标系建立方式为例进行说明，则设定终端的显示界面为xz平面，其中，终端的中心为坐标原点，指向终端右方的为x轴的正半轴，在显示界面上垂直于x轴的为z轴，xz平面内指向终端上方的为z轴的正半轴，垂直于显示平面的为y轴，xz平面外指向终端上方的为y轴的正半轴，详情请参考图2B所示的坐标系建立方式的示意图。
假设参数值是绕各个轴向转动的角度，则可以通过方向传感器测得终端绕x轴转动的第一参数值、绕y轴转动的第二参数值和绕z轴转动的第三参数值，根据测得的三个参数值确定终端的姿态。其中，可以通过陀螺仪测得终端的姿态，也可以通过陀螺仪和加速度传感器的结合测得终端的姿态，本实施例不作限定。
指南针APP根据终端的姿态测量出终端的各个方向，当摄像头位于终端背面时，摄像头的正对方向即终端的正对方向；当摄像头位于终端前面时，摄像头的正对方向与终端的正对方向相反。终端的正对方向是指由终端前面垂直指向终端背面的方向。
当显示界面与水平面垂直时，请参考图1B所示的摄像头正对方向的示意图。当显示界面与水平面不垂直时，请参考图2C所示的摄像头正对方向的示意图。图2C中用X轴、Y轴和Z轴表示终端建立的坐标系，摄像头的正对方向用箭头M表示，该箭头M与Y轴平行且与Y轴方向相反。
可选的，为了使用户明确转动方向，在转动终端的过程中，方向传感器可以每隔预定时间确定摄像头的正对方向。比如，假设终端从水平位置开始绕底边逆时针旋转，则图2D是根据本实施例示出的方向测量的应用图。其中，图2D(1)是旋转角度较小时的显示界面，图2D(2)是旋转角度较大时的显示界面。
在步骤204中，在实景中显示正对方向。
由于实景正对摄像头，因此，指南针APP测得的摄像头的正对方向即为实景方向，即可以向用户提供实景方向。
终端可以将测得的摄像头的正对方向实时显示在实景中。其中，终端可以将正对方向以指针的形式显示在实景中，或，优选地，可以将正对方向以数字的形式显示在实景中，以提高方向指示的精确性。
在步骤205中，根据正对方向确定其它方向，该其它方向包括与正对方向相反的方向和与正对方向垂直的方向；将其它方向对应显示在显示界面中。
终端可以根据摄像头的正对方向计算出与该正对方向相反的方向和与该正对方向垂直的方向，并将计算得到的方向分别显示在显示界面中的相对位置处。
图2E是根据本实施例示出的终端显示方向的示意图。当指南针APP测得摄像头的正对方向是“北10°”且将“北10°”显示在显示界面的上方时，将“北10°”顺时针旋转90度，得到与“北10°”垂直的方向“东100°”，将“东100°”显示在显示界面的右方；将“北10°”顺时针旋转180度，得到与“北10°”相反的方向“南190°”，将“南190°”显示在显示界面的下方；将“北10°”顺时针旋转270度，得到与“北10°”垂直的方向“西280°”，将“西280°”显示在显示界面的坐方。
需要补充说明的是，该方法，还包括：
1)预先设定基准方向；
2)计算测得的正对方向相对于基准方向的偏转角度；
3)将偏转角度显示在显示界面中。
其中，基准方向可以进行设置和修改。比如，起始方向是“北0°”，或，起始方向是“东南130°”等。
图2F是根据本实施例示出的偏转角度的应用图。其中，预先设置的基准方向是“北0°”，假设终端测得的正对方向是“南180°”，则计算得到的偏转角度是180°，终端在显示界面中显示“基于起始方向北偏转180°”的提示信息，以指示物体相对于基准方向的偏转。
综上所述，本公开提供的方向测量方法，通过当终端运行指南针APP时，启动摄像 头，通过摄像头获取实景；根据指南针APP确定摄像头的正对方向；在实景中显示正对方向，可以将摄像头的正对方向作为实景方向直接显示在实景中，解决了终端无法向用户提供现实场景中的方向的问题，达到了扩展终端的方向测量功能的效果。
另外，通过预先设定基准方向；计算测得的正对方向相对于基准方向的偏转角度；将偏转角度显示在显示界面中，可以根据设置的基准方向和显示的偏转角度确定实景的物体方向，达到了进一步扩展终端的方向测量功能的效果。
