在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。
本公开的头戴式显示设备可以是智能眼镜或者其他具有摄像头的智能设备，其中，智能眼镜例如可以是AR眼镜，也可以是VR眼镜，用户是指头戴式显示设备的佩戴者，用户将头戴式显示设备佩戴于肩部以上，例如可以是佩戴于眼睛前方。
本公开的头戴式显示设备可以包括显示屏，用户使用时显示屏正对目标用户的眼睛，用户可以通过头戴式显示设备，看见叠加了虚拟信息的真实世界，也可以通过头戴式显示设备，看见通过计算机模拟的虚拟世界。
本公开的头戴式显示设备上设置有摄像头，可以通过摄像头进行拍摄图像。下面以头戴式显示设备为AR眼镜为例进行说明。
请参见图1，图1为本公开提供的一种佩戴AR眼镜的用户的视野示意图。AR眼镜上安装有摄像头，假设摄像头的拍摄范围为AR眼镜的正前方，由于摄像头的视场角限制，摄像头可以拍摄到佩戴AR眼镜的用户眼球正视前方的画面，即摄像头的拍摄范围101。用户可以在无需调整自己的头部，而转动眼睛的情况下，看见相比于摄像范围101 更大的范围内的物体，即用户的视野范围102。
对于拍摄范围内位置103可以为摄像头的焦点，而佩戴AR眼镜的用户的眼睛实际看的位置，即人眼注视点，可以与摄像头的焦点重合，即为位置103；也可以为拍摄范围内除位置103外其他偏离位置103的位置，例如，位置104；还可以为视野范围102内出拍摄范围101以外的任一位置，例如，位置105。
本公开提供一种拍摄方法，在用户佩戴头戴式显示设备，需要通过头戴式显示设备上的摄像头进行拍摄图像时，头戴式显示设备可以通过显示屏实时显示摄像头捕捉的画面，从而使得用户可以看到摄像头当前获取到的画面。
本公开提供一种拍摄方法，在用户佩戴头戴式显示设备，需要通过头戴式显示设备上的摄像头进行拍摄图像时，头戴式显示设备根据人眼注视点和摄像头的拍摄参数信息，确定并显示提示针对所述摄像头方向的调整的指示图形，以使用户根据指示图形调整所述摄像头方向，当指示图形指示无需调整所述摄像头方向时，则用户的眼睛看到的画面与摄像头拍摄的画面一致，此时头戴式显示设备可以进行拍摄图像，使得头戴式显示设备拍摄的图像与用户看到的画面一致，提高了拍摄效率和用户体验。另外，本公开的方法避免了通过显示屏实时显示摄像头捕捉的画面时，人眼看到的是摄像头捕捉的画面与人眼看到的现实的画面相叠加的效果，从而避免用户出现眩晕的情况。摄像头实时显示摄像头捕捉的画面会使得功耗增大，甚至造成头戴式显示设备发热，本公开的方法通过显示指示图像，降低了头戴式显示设备的功耗，并不会出现发热等给用户带来不良体验的现象，提高了用户体验。
下面以几个具体的实施例以智能眼镜为例对本公开的技术方案进行描述，与智能眼镜类似的其他可穿戴设备的实现方式与本公开描述的技术方案相似，本公开不做赘述。
图2为本公开提供的一种拍摄方法的流程示意图，如图2所示， 本实施例的方法由上述头戴式显示设备执行，本实施例的方法如下：
S201、获取人眼注视点的位置信息和摄像头的拍摄参数信息。
用户佩戴头戴式显示设备后，当想要对所看到的画面进行拍摄时，头戴式显示设备获取人眼注视点的位置信息和摄像头的拍摄参数信息。
其中，人眼注视点为用户双眼实际看的空间位置。可以通过对用户双眼进行眼动追踪确定人眼注视点，也可以通过其他方式确定人眼注视点，本公开对此不做限定。需要说明的是，由于双眼在观察物体时，并不一定看的是空间中精确的一个点，也可能是一个较小的范围，因此，人眼注视点并不一定是空间中精确的一个点，也可能是一个预设的区域范围。
其中，拍摄参数信息包括：焦点的位置信息或者拍摄范围。
其中，摄像头的焦点可以为图1中所示的位置103。
其中，拍摄范围可以为图1中所示的拍摄范围101。
S202、根据人眼注视点的位置信息和摄像头的拍摄参数信息，确定并显示指示图形。
头戴式显示设备可以在确定进行拍摄以后，实时获取人眼注视点的位置信息和摄像头的拍摄参数信息，根据获取到的人眼注视点的位置信息和摄像头的拍摄参数信息，确定指示图形，并通过显示屏显示指示图形。
其中，指示图形用于指示针对所述摄像头方向的调整。身体姿态可以包括但不限于头部姿态，即用户的头部位置，面部朝向等信息。
其中，指示图形可以为两个形状，其中一个形状表示用户不需要调整所述摄像头方向，另一个形状表示用户需要调整所述摄像头方向。在用户看到指示图形指示需要调整所述摄像头方向时，进行调整自身的身体姿态，从而当用户将身体姿态调整到不需要再调整所述摄像头方向时，指示图像相应变成另一个形状。
指示图形也可以随着人眼注视点的位置信息和摄像头的拍摄参数 信息的变化进行相应的变化，也就是，在不同人眼注视点的位置信息和摄像头的拍摄参数信息的条件下，指示图形的形状不相同。在用户看到指示图形时，可以进行调整自身的身体姿态，在用户调整自身的身体姿态的过程中，头戴式显示设备也实时获取人眼注视点的位置信息和摄像头的拍摄参数信息，从而使得指示图形随用户身体姿态的调整而变化。
可选的，指示图形可以为四边形，该四边形为畸变的梯形、正方形或者矩形等，也可以为圆形或者椭圆形等，也可以为其他图形，对于指示图形的具体形状本公开不做限定。由于摄像头实际拍摄的画面一般为矩形，例如，可以为长宽比为16:9的矩形，因此，指示图形采用畸变的梯形更容易让用户理解指示图形的含义。
其中，显示指示图形的位置可以将指示图形显示在显示屏的中心位置。也可以在人眼注视点的位置相对于显示屏的位置，显示指示图形。还可以将指示图形显示在显示屏的其他位置，本公开对此不做限定。
本实施例，在用户佩戴头戴式显示设备，需要通过头戴式显示设备上的摄像头进行拍摄图像时，头戴式显示设备根据人眼注视点和摄像头的拍摄参数信息，确定并显示提示针对所述摄像头方向的调整的指示图形，以使用户根据指示图形调整所述摄像头方向，从而为用户指示了明确的调整方向，避免用户盲目的调整，提高了调整效率。
可选的，在图2所示实施例的基础上，进一步地，在S202之后还可以包括S203，如图3所示：
S203、在指示图形指示无需调整所述摄像头方向的情况下，执行拍摄图像。
当指示图形指示无需调整所述摄像头方向的情况下，说明当前用户双眼所看的物体正是摄像头现在拍摄的物体，从而头戴式显示设备控制摄像头拍摄图像。
本实施例，当指示图形指示无需调整所述摄像头方向时，则用户 的眼睛看到的画面与摄像头拍摄的画面一致，此时头戴式显示设备可以进行拍摄图像，使得头戴式显示设备拍摄的图像与用户看到的画面一致，提高了拍摄效率和用户体验。另外，本实施例的方法避免了通过显示屏实时显示摄像头捕捉的画面时，人眼看到的是摄像头捕捉的画面与人眼看到的现实的画面相叠加的效果，从而避免用户出现眩晕的情况。摄像头实时显示摄像头捕捉的画面会使得功耗增大，甚至造成头戴式显示设备发热，本公开的方法通过显示指示图像，降低了头戴式显示设备的功耗，并不会出现发热等给用户带来不良体验的现象，提高了用户体验。
下面以在展馆中用户佩戴AR眼镜参观为例说明本公开的方法的一种具体的应用场景。用户佩戴AR眼镜进行参观时，用户可透过AR眼镜看到展馆中的物品，同时，AR眼镜也可以在其显示屏上显示相关的物品介绍文字或者视频。用户需要对某个感兴趣的物品进行拍摄时，AR眼镜对确定人眼注视点和摄像头的参数信息，通过AR眼镜的显示屏上显示指示图形，用以提示用户当前注视的位置与摄像头实际拍摄的画面是否相符，从而使得用户可以根据指示图形调整自身身体姿态，当指示图形指示无需调整所述摄像头方向时，则用户的眼睛看到的画面与摄像头拍摄的画面一致，此时头戴式显示设备可以进行拍摄图像。
在图2或图3所示实施例的基础上，进一步地，拍摄参数信息可以包括：焦点的位置信息，在步骤S202中，可以确定的人眼注视点与摄像头的焦点之间的第一距离，通过第一距离与第一预设阈值的数值大小关系，显示不同的指示图形。下面以图4所示实施例进行详细说明。
请参见图4，图4为本公开提供的另一种拍摄方法的流程示意图，图4是在图2或图3所示实施例的基础上，进一步地，S202可以通过如下步骤S2022-S2024实现：
S2021、根据人眼注视点的位置信息和摄像头的焦点的位置信息，确定人眼注视点与摄像头的焦点之间的第一距离。
S2022、判断第一距离是否小于等于第一预设阈值。
若第一距离小于等于第一预设阈值，则继续执行S2023，若第一距离大于第一预设阈值，则继续执行S2024。
通过判断第一距离和第一预设阈值的大小关系，可以确定用户当前注视的物体是摄像头当前拍摄图像之间是否有偏差。若第一距离小于等于第一预设阈值，则说明用户当前注视的物体是摄像头当前拍摄图像中会呈现的，则可以显示第一指示图形。
其中，第一预设阈值为预先设置的大于等于0的任一值。例如，当第一预设阈值为0时，则表示当人眼注视点与摄像头的焦点完全重合时，显示第一指示图形。而对于使得人眼注视点和摄像头的焦点完全重合并不容易做到，因此可以在允许的误差范围内设置第一预设阈值为大于0的任一值。
S2023、确定并显示第一指示图形。
其中，第一指示图形用于指示无需调整所述摄像头方向。
继续执行S203。
S2024、在第一距离大于第一预设阈值时，确定并显示第二指示图形。
其中，第二指示图形用于指示需要调整所述摄像头方向。
返回执行S2021。
在第一距离和第一预设阈值的大小关系不同时，显示的指示图形也不相同，从而用户可以根据显示的为第一指示图像还是第二指示图像知晓是否需要调整所述摄像头方向。
其中，第二指示图形为一种与第一指示图形不同的图形。
可选的，第一指示图形为矩形，第二指示图形为四边形，四边形其中一个角为锐角。
可选的，第二指示图形的形状还用于指示用户调整所述摄像头方向的幅度。例如，第二指示图形的形状为其中一个角为锐角的四边形时，则该锐角的角度可以用于指示用户调整所述摄像头方向的幅度。
本实施例，头戴式显示设备通过根据人眼注视点的位置信息和摄像头的焦点的位置信息，确定人眼注视点与摄像头的焦点之间的第一距离，通过判断第一距离是否小于等于第一预设阈值，确定人眼注视点与摄像头的焦点之间的偏离程度，从而显示不同的指示图形，以提示用户是否需要调整其身体姿态，更准确的确定并显示指示图形，从而更准确的通过指示图形给用户提示。
在图4所示实施例的基础上，进一步地，第二指示图形的确定的一种可能的实现方式中，第二指示图形可以为一种预设的固定图形。
则通过第一指示图形和第二指示图形这两种形状指示是否需要调整所述摄像头方向。
另一种可能的实现方式中，第二指示图形可以根据人眼注视点偏离摄像头的焦点的方向确定。下面以具体的实施例进行详细说明。
在图4所示实施例的基础上，在步骤S2024中确定人眼注视点偏离摄像头焦点的位移，从而确定第二指示图形。S2024可以通过如下步骤1和步骤2实现：
步骤1、根据人眼注视点的位置信息和摄像头的焦点的位置信息，确定人眼注视点偏离摄像头的焦点的方向。
步骤2、根据人眼注视点偏离摄像头的焦点的方向，确定并显示第二指示图形。
本实施例，第二指示图形根据人眼注视点偏离摄像头的焦点的方向确定，从而使得显示的第二指示图形能够提示用户偏离方向，用户可以基于第二指示图形确定需要调整身体姿势的方向，从而使得用户可以按照该方向调整身体姿势，第二指示图形的指导性更强，用户调整的时候更有针对性，提高了用户调整身体姿势的效率，同时也就提高了拍摄效率和用户体验。
再一种可能的实现方式中，第二指示图形可以根据第一距离和人眼注视点偏离摄像头的焦点的方向确定。下面以具体的实施例进行详细说明。
步骤2可以通过如下方式实现：
根据第一距离和人眼注视点偏离摄像头的焦点的方向，确定并显示第二指示图形。
本实施例，当第一距离大于第一预设阈值时，人眼注视点的位置与摄像头的焦点之间的距离较大，此时需要用户根据第二指示图形调整其身体姿态，确定人眼注视点相对摄像头的焦点偏移的方向，从而根据第一距离和第一方向，得到第二指示图形，使得第二指示图形既能指示是否需要调整所述摄像头方向，又能指示调整所述摄像头方向的方向，从而使得第二指示图形更准确、直观，进而使得用户调整的时候更有针对性，提高了用户调整身体姿势的效率，同时也就提高了拍摄效率和用户体验。。
进一步地，第二指示图形包括：指示方向和指示幅度。在步骤2中，可以根据第一距离，确定第二指示图形的指示幅度。根据人眼注视点偏离摄像头的焦点的方向，确定第二指示图形的指示方向。根据指示幅度和指示方向，确定并显示指示图形。
本实施例，第二指示图形根据第一距离以及人眼注视点偏离摄像头的焦点的方向确定，从而使得显示的第二指示图形能够提示人眼注视点偏离摄像头的焦点的方向以及偏离程度，用户可以基于第二指示图形确定需要调整身体姿势的方向和幅度，从而使得用户可以按照该方向以及该幅度调整身体姿势，第二指示图形的指导性更强，用户调整的时候更有针对性，提高了用户调整身体姿势的效率，同时也就提高了拍摄效率和用户体验。
下面以用户佩戴AR眼镜为例进行说明。AR眼镜上设置摄像头。请参见图5A和图5B，图5A为本公开提供的一种人眼注视点和摄像头的焦点的位置关系示意图，图5B为图5A的平面示意图。如图5A所示，可以以摄像头为原点，以原点到摄像头的焦点方向为Y轴正方向，双眼所在直线为X轴，建立空间X-Y-Z直角坐标系。人眼注视点501与摄像头的焦点502的第一距离的计算可以转换到如图5B的X-Z平面 中，第一距离为在X-Z平面中人眼注视点501与摄像头的焦点502之间的距离，人眼注视点501偏离摄像头的焦点502的方向即为图5B中X-Z平面中摄像头的焦点502指向人眼注视点501的方向。
相应的，可以根据X-Z平面中人眼注视点501与摄像头的焦点502的第一距离，以及人眼注视点501偏离摄像头的焦点502的方向，确定第二指示图形。
本实施例以第二指示图形是有一个角为锐角的四边形，第一指示图形是矩形为例进行说明。请参见图5C、图5D、图5E和图5F，图5C、图5D、图5E和图5F分别为本公开提供的一种第二指示图形的示意图。
当人眼注视点501与摄像头的焦点502之间的第一距离小于等于第一预设阈值时，可以认为人眼注视点501与摄像头的焦点502重合，此时确定的第一指示图形为矩形。
当人眼注视点501与摄像头的焦点502之间的第一距离大于第一预设阈值时，可以认为人眼注视点501与摄像头的焦点502不重合，从而根据X-Z平面中人眼注视点501与摄像头的焦点502的第一距离，以及人眼注视点501偏离摄像头的焦点502的方向，确定第二指示图形503。
具体的，第二指示图形503的形状为在矩形的基础上畸变得到的，可以根据人眼注视点501偏离摄像头的焦点502的方向，使得矩形的两条边沿着该方向畸变。人眼注视点501与摄像头的焦点502之间的第一距离越大，第二指示图形503的锐角越小，也就是矩形的两条的畸变幅度越大。
可选的，图5C、图5D、图5E和图5F中所示的第二指示图形503中的虚线矩形的中心点到锐角顶点的距离可以与第一距离成预设比例。如图5C和图5D中的第二指示图形503所示的，图5D中的第一距离大于图5C中的第一距离，则相应的，图5D对应的第二指示图形503的锐角比图5C对应的第二指示图形503小，同样，图5D对应的 第二指示图形503的矩形畸变幅度比图5C对应的第二指示图形503的矩形畸变幅度大。
在图2所示实施例的基础上，拍摄参数信息包括：拍摄范围时，步骤S502中，可以确定的人眼注视点与摄像头的拍摄范围的中心点之间的第二距离，通过第二距离与第二预设阈值的数值大小关系，显示不同的指示图形。下面以图6所示实施例进行详细说明。
请参见图6，图6为本公开提供的另一种拍摄方法的流程示意图，图6是在图2所示实施例的基础上，进一步地，S202可以通过如下步骤S202a-S202d实现：
S202a、根据人眼注视点的位置信息和摄像头的拍摄范围，确定人眼注视点与摄像头的拍摄范围的中心点之间的第二距离。
S202b、判断第二距离是否小于等于第二预设阈值。
若第二距离小于等于第二预设阈值，则继续执行S202c。若第二距离大于第二预设阈值，则继续执行S202d。
通过判断第二距离和第二预设阈值的大小关系，可以确定用户当前注视的物体是摄像头当前拍摄范围之间是否有偏差。若第二距离小于等于第二预设阈值，则说明用户当前注视的物体是摄像头当前拍摄图像中会呈现的，则可以显示第一指示图形。
其中，第二预设阈值为预先设置的大于等于0的任一值。例如，当第二预设阈值为0时，则表示当人眼注视点与摄像头的拍摄范围的中心点完全重合时，显示第一指示图形。而对于使得人眼注视点和摄像头的拍摄范围的中心点完全重合并不容易做到，因此可以在允许的误差范围内设置第一预设阈值为大于0的任一值。
S202c、确定并显示第一指示图形。
其中，第一指示图形用于指示无需调整所述摄像头方向。本实施例中的第一指示图形与图3所示实施例中的第一指示图形相同，在此不再赘述。
继续执行S203。
S202d、确定并显示第二指示图形。
其中，第二指示图形用于指示需要调整所述摄像头方向。本实施例中的第二指示图形与图4所示实施例中的第二指示图形相同，在此不再赘述。
返回执行S202a。
本实施例，头戴式显示设备通过根据人眼注视点的位置信息和摄像头的拍摄范围的中心点的位置信息，确定人眼注视点与摄像头的拍摄范围的中心点之间的第二距离，通过判断第二距离是否小于等于第二预设阈值，确定人眼注视点与摄像头的拍摄范围的中心点之间的偏离程度，从而显示不同的指示图形，以提示用户是否需要调整其身体姿态，更准确的确定并显示指示图形，从而更准确的通过指示图形给用户提示，用户调整的时候更有针对性，提高了用户调整身体姿势的效率，同时也就提高了拍摄效率和用户体验。
在图6所示实施例的基础上，进一步地，第二指示图形的确定的一种可能的实现方式中，第二指示图形可以为一种预设的固定图形。
则通过第一指示图形和第二指示图形这两种形状指示是否需要调整所述摄像头方向。
另一种可能的实现方式中，第二指示图形可以根据人眼注视点偏离摄像头的拍摄范围的中心点的方向确定。下面以具体的实施例进行详细说明。
在图4所示实施例的基础上，在步骤S202d中确定人眼注视点偏离摄像头拍摄范围的中心点的位移，从而确定第二指示图形。S202d可以通过如下步骤a和步骤b实现：
步骤a、根据人眼注视点的位置信息和摄像头的拍摄范围的中心点的位置信息，确定人眼注视点偏离摄像头的拍摄范围的中心点的方向。
步骤b、根据人眼注视点偏离摄像头的拍摄范围的中心点的方向，确定并显示第二指示图形。
本实施例，第二指示图形根据人眼注视点偏离摄像头的拍摄范围 的中心点的方向确定，从而使得显示的第二指示图形能够提示用户偏离方向，用户可以基于第二指示图形确定需要调整身体姿势的方向，从而使得用户可以按照该方向调整身体姿势，第二指示图形的指导性更强，用户调整的时候更有针对性，提高了用户调整身体姿势的效率，同时也就提高了拍摄效率和用户体验。
再一种可能的实现方式中，第二指示图形可以根据第一距离和人眼注视点偏离摄像头的拍摄范围的中心点的方向确定。下面以具体的实施例进行详细说明。
步骤b可以通过如下方式实现：
根据第一距离和人眼注视点偏离摄像头的拍摄范围的中心点的方向，确定并显示第二指示图形。
本实施例，当第一距离大于第一预设阈值时，人眼注视点的位置与摄像头的拍摄范围的中心点之间的距离较大，此时需要用户根据第二指示图形调整其身体姿态，确定人眼注视点相对摄像头的拍摄范围的中心点偏移的方向，从而根据第一距离和第一方向，得到第二指示图形，使得第二指示图形既能指示是否需要调整所述摄像头方向，又能指示调整所述摄像头方向的方向，从而使得第二指示图形更准确、直观，进而使得用户能够更快速准确的调整自身的身体姿态，完成拍摄。
进一步地，第二指示图形包括：指示方向和指示幅度。在步骤b中，可以根据第一距离，确定第二指示图形的指示幅度。根据人眼注视点偏离摄像头的拍摄范围的中心点的方向，确定第二指示图形的指示方向。根据指示幅度和指示方向，确定并显示指示图形。
本实施例，第二指示图形根据第一距离以及人眼注视点偏离摄像头的拍摄范围的中心点的方向确定，从而使得显示的第二指示图形能够提示人眼注视点偏离摄像头的拍摄范围的中心点的方向以及偏离程度，用户可以基于第二指示图形确定需要调整身体姿势的方向和幅度，从而使得用户可以按照该方向以及该幅度调整身体姿势，第二指示图 形的指导性更强，使得用户调整身体姿势的效率更高。
在上述图2-图6任一所示实施例的基础上，进一步地，在一些场景中，有些用户并不清楚指示图形实际的含义，用户只是根据指示图形进行调身体姿态，可能需要花费大量的时间，因此，本实施例可以在步骤S102中显示指示图形的同时，输出语音提示，该语音提示用于指示针对所述摄像头方向的调整，例如，可以输出“请调整头部方向”或者“请保持当前头部姿态，进行拍摄”等。从而使得用户更明确当前是否需要调整所述摄像头方向。
在上述图2-图5任一所示实施例的基础上，进一步地，在指示图形指示需要调整所述摄像头方向时，指示图形中还显示有调整方向标识，调整方向标识用于指示用户根据调整方向标识调整所述摄像头方向。
通过显示调整方向标识，使得用户更容易理解需要如何调整自身的身体姿态，用户调整的时候更有针对性，提高了用户调整身体姿势的效率，同时也就提高了拍摄效率和用户体验。
在上述图2-图5任一所示实施例的基础上，进一步地，在指示图形指示无需调整所述摄像头方向时，指示图形以预设颜色显示。例如，可以为绿色或者黄色显示指示图形，本公开对此不做限定。
由于当人眼注视点与摄像头实际拍摄的范围之间的偏差越小，用户越不容易分辨出当前的指示图像为第一指示图形还是第二指示图形，因此，可以通过将第二指示图形以预设颜色显示，从而起到更好的提示用户当前是否需要调整所述摄像头方向的作用。
在上述图3-图6任一所示实施例的基础上，进一步地，步骤S203的一种可能的实现方式中，头戴式显示设备可以在指示图形指示无需调整所述摄像头方向时，直接执行拍摄图像。示例性的，在图4或图6所示的实施例中，头戴式显示设备在指示图形为第一指示图形时，直接执行拍摄图像。下面以图7所示实施例进行详细说明。
在指示图形指示无需调整所述摄像头方向时，执行拍摄图像。
本实施例，头戴式显示设备通过在指示图形指示无需调整所述摄像头方向时，直接执行拍摄图像，使得头戴式显示设备在拍摄画面与人眼看到画面相符时，自动执行拍摄图像，提高了拍摄图像的效率。
进一步地，在指示图形指示无需调整所述摄像头方向时，执行拍摄图像之前，还包括：
接收用户设置的自动拍摄功能开启执行。
其中，自动拍摄功能用于在指示图形指示无需调整所述摄像头方向时，直接触发执行拍摄图像。
本实施例，通过在拍摄图像前先接受用户设置的自动拍摄功能开启执行，则在指示图形指示无需调整所述摄像头方向时，头戴式显示设备可以直接触发执行拍摄图像，自动拍摄图像的过程是用户许可的，符合系统安全性，并充分考虑用户的需求。
在上述图3-图6任一所示实施例的基础上，进一步地，步骤S203的另一种可能的实现方式中，可以根据指示图形指示无需调整所述摄像头方向以后，用户向头戴式显示设备输入用于指示拍摄的触发指令，从而头戴式显示设备执行拍摄图像。下面以具体的实施例进行详细说明。步骤S203可以通过如下步骤实现：
在指示图形指示无需调整所述摄像头方向后，接收用户输入的触发指令，执行拍摄图像。
用户根据当前指示图形的形状，可以确定是否需要调整所述摄像头方向，当指示图形指示无需调整所述摄像头方向后，用户可以向头戴式显示设备输入触发指令，从而触发头戴式显示设备执行拍摄图像。
本实施例，头戴式显示设备通过接收用户输入的触发指令以后，再执行拍摄图像，充分考虑用户需求，在用户触发拍摄时才执行拍摄，从而保证每次拍摄的图像都是用户需要的。
在上述实施例的基础上，进一步地，在步骤S201之前还可以包括如下步骤：
接收拍摄启动指令。
其中，拍摄启动指令用于指示头戴式显示设备执行拍摄。拍摄启动指令可以为用户输入的语音指令、手势动作指令或者触摸按钮指令。其中，语音指令可以为“拍照”或“开始拍摄”等。手势动作指令可以为握拳，手指在空中点击操作等。触摸按钮指令可以为用户按下头戴式显示设备上设置的拍摄按钮。
进一步地，在接收拍摄启动指令以后，头戴式显示设备可以在显示屏中显示表示拍摄范围的矩形框，例如，可以为16:9的矩形框，从而提示用户拍摄模式开启。
在上述实施例的基础上，进一步地，在步骤S203中执行拍摄图像可以包括如下步骤：
控制摄像头根据人眼注视点的位置信息所在的物体进行对焦，通过摄像头拍摄图像。
本实施例，头戴式显示设备控制摄像头在对人眼注视点的位置信息所在的物体进行对焦以后，再执行拍摄图像，从而使得拍摄得到的图像即为人眼看到的画面，并且人眼主要注视的物体在拍摄画面中是清晰的。
