在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本公开实施例的描述中，除非另有说明，“多个”的含义是指两个或者两个以上， 例如，多个处理单元是指两个或者两个以上的处理单元等；多个元件是指两个或者两个以上的元件等。
下面首先对本公开的权利要求书和说明书中涉及的一些名词或者术语进行解释说明。
全景拍摄：是指以某个点为中心进行水平α度(例如0度＜α≤360度)和垂直β度(例如0度＜β≤180度)拍摄，将所拍摄的多个图像拼接成一个全景图像。全景拍摄方法涉及图像拍摄方法和图像拼接方法。
本公开实施例提供一种全景拍摄方法及终端设备，可以在拍摄过程中，接收用户的第一输入；响应于该第一输入，控制终端设备的可转动摄像头沿第一方向依次转动N次，并在该摄像头每次暂停转动后，拍摄一个图像；且将拍摄的N个图像拼接成目标全景图像，N为大于1的整数。通过该方案，本公开实施例可以在用户触发拍摄全景图像的情况下(例如用户选择N连拍)，通过控制摄像头自动转动N次，且每次转动暂停后拍摄一次，在依次转动N次之后获得N个图像，从而将N个图像合成全景图像。如此，在拍摄全景图像过程中，终端设备对全景拍摄智能控制，无需用户人为地对终端设备进行操作，从而可以避免终端设备位移对全景图像的合成效果产生影响。
本公开实施例中的终端设备可以为具有操作***的终端设备。该操作***可以为安卓(Android)操作***，可以为ios操作***，还可以为其他可能的操作***，本公开实施例不作具体限定。
下面以安卓操作***为例，介绍一下本公开实施例提供的全景拍摄方法所应用的软件环境。
如图1所示，为本公开实施例提供的一种可能的安卓操作***的架构示意图。在图1中，安卓操作***的架构包括4层，分别为：应用程序层、应用程序框架层、***运行库层和内核层(具体可以为Linux内核层)。
其中，应用程序层包括安卓操作***中的各个应用程序(包括***应用程序和第三方应用程序)。
应用程序框架层是应用程序的框架，开发人员可以在遵守应用程序的框架的开发原则的情况下，基于应用程序框架层开发一些应用程序。

本公开实施例中的终端设备可以为移动终端，也可以为非移动终端。示例性的，移动终端可以为手机、平板电脑、笔记本电脑、掌上电脑、车载终端、可穿戴设备、超级移动 个人计算机(ultra-mobile personal computer，UMPC)、上网本或者个人数字助理(personal digital assistant，PDA)等，非移动终端可以为个人计算机(personal computer，PC)、电视机(television，TV)、柜员机或者自助机等，本公开实施例不作具体限定。
本公开实施例提供的全景拍摄方法的执行主体可以为上述的终端设备，也可以为该终端设备中能够实现该全景拍摄方法的功能模块和/或功能实体，具体的可以根据实际使用需求确定，本公开实施例不作限定。下面以终端设备为例，结合各个附图，对本公开实施例提供的全景拍摄方法进行示例性的说明。
如图2所示，本公开实施例提供一种全景拍摄方法，该方法应用于包括可转动的摄像头的终端设备，该全景拍摄方法可以包括下述的步骤200-步骤203。
步骤200、在拍摄过程中，终端设备接收用户的第一输入。
本公开实施例中，如果用户需要通过终端设备进行全景拍摄，那么此时在终端设备运行相机应用的情况下，用户可以通过第一输入，触发开启相机应用中的全景功能(也称为全景模式)，进而终端设备可以采用全景功能进行拍摄，并获得全景图像(也称为全景照片)。
可选的，本公开实施例中，上述用户的第一输入可以为用户对相机应用中的“全景”选项或“全景”控件的选择输入，也可以为用户对终端设备中的全景快捷按键的触控输入，还可以为其它任意满足实际使用需求的输入，具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，上述全景拍摄可以为基本全景拍摄，也可以为趣味全景拍摄(即通过该趣味全景功能拍摄得到的全景图像可以显示出对象“分身”效果等)，还可以包括其它任意可能的全景拍摄。本公开实施例提供的全景拍摄方法既可以适用于基本全景拍摄，也可以适用于趣味全景拍摄，还可以适用于其它可能的全景拍摄，具体可以根据实际使用需求确定，本公开实施例不作限定。
步骤201、终端设备响应于第一输入，控制摄像头沿第一方向依次转动N次。
步骤202、在摄像头每次暂停转动后，终端设备拍摄一个图像。
本公开实施例中，上述终端设备的摄像头为可转动摄像头，该可转动摄像头可以以某个点为中心，沿某一方向转动特定角度γ(例如0度＜γ≤360度)。
本公开实施例中，在用户对终端设备进行第一输入，触发终端设备开启全景功能之后，终端设备可以控制终端设备的摄像头转动，在摄像头暂停转动后进行拍摄，在摄像头拍摄完成后再次转动，在摄像头暂停转动后再次进行拍摄，依次类推，直至摄像头转动N次之后拍摄过程结束。
具体的，摄像头转动一次，拍摄得到一个图像；摄像头转动两次，拍摄得到两个图像；以此类推，摄像头转动N次，拍摄得到N个图像。
可选的，本公开实施例中，上述摄像头的转动次数(即上述的N次)可以是终端设备默认设置的，也可以由用户自定义设置(例如用户可以在全景功能设置中选择连拍次数)。其中，N可以为大于1的整数，例如N可以为2，也可以为5，还可以为10，或者可以为其它满足实际使用需求的数值。具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，以用户自定义设置为例，若用户在全景功能设置中选择5连拍(即N为5)，则终端设备可以控制摄像头沿第一方向依次转动5次。
可选的，本公开实施例中，上述第一方向可以为逆时针方向，也可以为顺时针方向，还可以为其它任意满足实际使用需求的方向，具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，上述第一方向可以是终端设备默认设置的，也可以由用户在全景功能设置中选择，具体可以根据实际使用需求确定，本公开实施例不作限定。
步骤203、终端设备将拍摄的N个图像拼接成目标全景图像。
本公开实施例中，终端设备在拍摄得到N个图像之后，可以采用图像拼接技术或算法，将拍摄得到的N个图像拼接成目标全景图像。
其中，上述图像拼接技术是将一组相互间重叠部分的图像序列进行空间匹配对准，经重采样合成后形成一个包含各图像序列信息的宽视角场景的、完整的、高清晰的新图像的技术。对于图像拼接技术的描述具体可以参见相关技术中对图像拼接技术的描述，此处不予赘述。
示例性的，以基本全景拍摄为例，将N个图像拼接合成的目标全景图像可以呈现出较宽视场的画面。以趣味全景拍摄为例，将N个图像拼接合成的目标全景图像呈现出较宽视场的画面，且画面中的对象可以呈现“分身”效果。
本公开实施例中，终端设备可以响应于用户的第一输入，控制摄像头沿第一方向转动，并在摄像头暂停转动后，拍摄得到一个图像。然后，终端设备控制摄像头沿第一方向继续转动，并在摄像头暂停转动后，再次对目标对象拍摄，得到另一个图像。以此类推，终端设备可以控制摄像头沿第一方向依次转动N次，并在摄像头每次暂停转动后，拍摄得到一个图像，如此在摄像头转动N次后，最终得到N个图像，并且终端设备将拍摄得到的N个图像拼接成目标全景图像。通过本方案，在拍摄全景图像过程中无需用户对终端设备进行操作，从而实现了终端设备的智能全景拍摄，如此可以提升终端设备拍摄全景图像的灵活性和便捷性。
通过上述方案，由于在全景拍摄过程中终端设备可以控制摄像头自动转动并自动拍摄，因此可以避免由用户手动转动终端设备带来的摄像头抖动。如此，本公开实施例通过控制摄像头自动转动，在全景拍摄过程中多次拍摄的基准线基本保持一致，可以避免全景图像出现断层、模糊等现象，从而可以改善通过拼接得到的全景图像的显示效果。
此外，对于趣味全景拍摄过程，本公开实施例通过控制摄像头自动转动并自动拍摄，可以避免用户的多次触发拍摄操作，也避免趣味全景拍摄需要多人参与(本公开实施例中单人即可完成拍摄)，从而可以提升用户使用终端设备进行趣味全景拍摄的便捷性和灵活性。
本公开实施例提供的全景拍摄方法，可以在拍摄过程中，接收用户的第一输入；响应于该第一输入，控制终端设备的可转动摄像头沿第一方向依次转动N次，并在该摄像头每次暂停转动后，拍摄一个图像；且将拍摄的N个图像拼接成目标全景图像，N为大于1的整数。通过该方案，本公开实施例可以在用户触发拍摄全景图像的情况下(例如用户选择N连拍)，通过控制摄像头自动转动N次，且每次转动暂停后拍摄一次，在依次转动N次之后获得N个图像，从而将N个图像合成全景图像。如此，在拍摄全景图像过程中，终端设备对全景拍摄智能控制，无需用户人为地对终端设备进行操作，从而可以避免终端设备位移对全景图像的合成效果产生影响。
可选的，结合图2，如图3所示，在上述的步骤202之后，以及上述的步骤203之前，本公开实施例提供的全景拍摄方法还可以包括下述的步骤204。在此情况下，上述的步骤203具体可以通过下述的步骤203a实现。
步骤204、在每次拍摄一个图像之后，终端设备检测拍摄过程是否结束。
一方面，在上次拍摄得到一个图像之后，若终端设备检测拍摄过程未结束，则终端设备控制摄像头继续沿第一方向转动，并在摄像头暂停转动后，拍摄得到另一个图像；进一步的，在拍摄得到该另一个图像之后，终端设备继续检测拍摄过程是否结束；以此类推，在每次拍摄得到一个图像之后，终端设备检测拍摄过程是否结束，直至终端设备检测到拍摄过程结束为止。
另一方面，在每次拍摄得到一个图像之后，若终端设备检测到拍摄过程结束，则终端设备对拍摄得到的多个图像进行拼接，得到目标全景图像(即下述的步骤203a)。
可选的，本公开实施例中，上述步骤204具体可以通过下述的步骤204a实现。
步骤204a、终端设备检测拍摄的图像数量是否等于N。
其中，终端设备可以将拍摄得到的图像的数量与预设数量N进行比较，以检测拍摄得到的图像的数量和预设数量N的大小关系。具体的，在拍摄得到的图像的数量等于预设数量N的情况下，终端设备可以确定拍摄过程结束；在拍摄得到的图像的数量小于预设数量N的情况下，终端设备可以确定拍摄过程未结束。
本公开实施例中，上述预设数量N可以为用户选择的全景拍摄的连拍次数，也可以为终端设备默认设置的全景拍摄的连拍次数，具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，以用户选择全景拍摄的连拍次数为例，用户可以选择5连拍全景、8连拍全景或其它任意连拍全景。举例来说，假设用户选择5连拍全景(即预设数量为5)，那么在终端设备在检测拍摄得到的图像的数量达到5(即已拍摄图像的数量等于预设数量)的情况下，可以确定拍摄过程结束，那么在终端设备拍摄得到5个图像后结束拍摄。
可选的，本公开实施例中，终端设备还可以在预设范围内未扫描到对象的情况下，确定拍摄过程结束，如此实现终端设备对全景拍摄的智能控制。该预设范围可以为预设时长范围或预设角度范围。
举例来说，假设预设范围为预设时长范围，那么若终端设备在预设时长范围内未扫描到对象(例如在扫描1分钟后未扫描到对象)，则终端设备可以确定拍摄过程结束。
再举例来说，假设预设范围为预设角度范围，那么若终端设备在预设角度范围内未扫描到对象(例如在扫描360度后未扫描到对象)，则终端设备可以确定拍摄过程结束。
需要说明的是，本公开实施例终端设备检测拍摄是否结束的方法包括但不限于上述方式，还可以包括其它任意可能满足实际使用需求的方法，例如，终端设备可以在检测到目标对象的特定手势后结束拍摄。终端设备检测拍摄是否结束的方法具体可以根据实际使用需求确定，本公开实施例不作限定。
步骤203a、在检测到拍摄过程结束的情况下，终端设备将拍摄的N个图像拼接成目标全景图像。
通过该方案，在全景拍摄过程中，终端设备可以在每次拍摄得到一个图像之后，检测拍摄过程是否结束，并在检测到拍摄过程结束的情况下，终端设备将拍摄得到的N个图像 拼接成目标全景图像。如此，在拍摄全景图像过程中无需用户对终端设备进行操作，从而实现了终端设备对全景拍摄的智能控制。
需要说明的是，本公开实施例提供的全景拍摄方法中，终端设备可以控制摄像头沿第一方向转动N次，并在摄像头每次暂停转动后，拍摄得到一个图像。其中，本公开实施例提供了两种控制方法来控制摄像头暂停转动，即在摄像头识别到对象后，终端设备控制摄像头暂停转动；终端设备周期性地控制摄像头暂停转动。下面通过下述的第一实现方式和第二实现方式，分别对本公开实施例提供的两种控制方法进行详细描述。
第一实现方式
可选的，结合图2，如图4所示，在上述的步骤202之前，本公开实施例提供的全景拍摄方法还包括下述的步骤205和步骤206。相应地，上述的步骤202具体可以通过下述的步骤202a实现。
步骤205、在摄像头每次转动过程中，终端设备通过摄像头，识别对象。
可选的，上述的步骤205具体可以通过下述的步骤205a实现。
步骤205a、终端设备识别摄像头采集到的图像中是否包含人脸特征信息或者预设人脸特征信息。
可选的，本公开实施例中，上述人脸特征信息可以指任意人脸特征信息，上述预设人脸特征信息可以指用户预设的人脸特征信息，终端设备可以识别摄像头采集到的图像中是否包含人脸特征信息，也可以识别摄像头采集到的图像中是否包含预设人脸特征信息，具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，若终端设备识别到摄像头采集到的图像中包含人脸特征信息或者预设人脸特征信息，则终端设备控制摄像头暂停转动。若摄像头采集到的图像中不包含人脸特征信息或者预设人脸特征信息，则终端设备继续控制摄像头转动，直到摄像头识别到对象为止。
需要说明的是，本公开实施例不作限定终端设备识别对象的方向，例如，终端设备可以沿顺时针方向识别，或者可以沿逆时针方向识别，或者可以从任意位置开始识别。
步骤206、在通过摄像头识别到目标对象的情况下，终端设备控制摄像头暂停转动。
可选的，本公开实施例中，上述目标对象可以为人，也可以为动物，还可以为静物，或者可以为其它任意可能的对象，具体可以根据实际使用需求确定，本公开实施例不作限定。示例性的，以目标对象为人为例，一旦摄像头识别到同一个人，则终端设备控制摄像头暂停转动。
需要说明的是，在终端设备识别到目标对象之后，如果目标对象从取景框中消失，那么终端设备可以重新识别对象。
可选的，本公开实施例中，终端设备确定目标对象的方式可以为下述的(1)、(2)、(3)和(4)中的至少一种。
(1)终端设备将人物(例如通过人脸、腿、形状等算法)确定为目标对象。若终端设备检测到有人(通过人脸、腿、形状等算法)，则终端设备确定识别到目标对象。
(2)终端设备在扫描相册中的照片后，将出现次数最多的人脸确定为目标对象。若摄像头转动时识别到的人脸与目标对象匹配，则终端设备确定识别到目标对象。
(3)终端设备在扫描相册中的照片后，将所有扫描到的人脸确定为目标对象。若摄 像头转动时识别到的人脸与目标对象匹配，则终端设备确定识别到目标对象。
(4)终端设备将用户选择的对象，确定为目标对象。若摄像头转动时识别到的对象与目标对象匹配，则终端设备确定识别到目标对象。其中，用户可以通过下述的a、b、c中的任一项来选择目标对象。
a、假设终端设备自动扫描相册，并将扫描到的人脸以出现次数多少或拍摄时间等方式排序(例如，终端设备可以显示所有的人脸，也可以只显示最近或出现次数较多的人脸，供用户选择)，那么用户可以从排序后的照片中选择一个对象，确定为目标对象。
b、用户可以在相册已有照片中选择一个对象，作为目标对象。
c、用户可以在取景框中选择一个对象，作为目标对象。
下面参考图5至图8，示例性的说明用户通过终端设备选择全景拍摄的对象的过程。
如图5所示，终端设备可以显示用户选择界面30，该用户选择界面30中包括子界面31，该子界面31中显示有终端设备对相册扫描后智能检测到的对象(例如人脸图像)，供用户从中选择全景拍摄的对象。
如图5所示，该用户选择界面30中还包括控件32和控件33。若用户对控件32输入，则如图6所示，终端设备显示相册界面34，该相册界面中显示有相册中的多个照片。若用户从多个照片中选中一个照片，则如图7所示，终端设备显示照片35，供用户在照片35中选择全景拍摄的对象。若用户对控件33输入，则如图8所示，终端设备开启摄像头并显示取景框36，供用户从取景框36中显示的预览图像选择全景拍摄的对象。
步骤202a、在摄像头每次暂停转动后，终端设备对目标对象拍摄，得到一个图像。
本公开实施例中，终端设备可以控制摄像头沿第一方向依次转动N次，并在摄像头每次转动过程中，终端设备通过摄像头识别对象，且在通过摄像头识别到目标对象的情况下，终端设备控制摄像头暂停转动，并且在摄像头每次暂停转动之后，对目标对象拍摄，得到一个图像。
具体的，终端设备可以响应于用户的第一输入，控制摄像头沿第一方向转动，并在摄像头转动过程中，终端设备通过摄像头识别对象，且在通过摄像头识别到目标对象的情况下，终端设备控制摄像头暂停转动，并且在摄像头暂停转动后，对目标对象拍摄，得到一个图像。然后，终端设备控制摄像头沿第一方向继续转动，并在摄像头转动过程中，终端设备继续通过摄像头识别对象，且在通过摄像头识别到目标对象的情况下，终端设备控制摄像头暂停转动，并且在摄像头暂停转动后，再次对目标对象拍摄，得到另一个图像。以此类推，终端设备可以控制摄像头沿第一方向依次转动N次，并在摄像头每次暂停转动后，对目标对象拍摄得到一个图像，如此在摄像头转动N次后，最终得到N个图像。
通过本方案，在摄像头识别到对象后，终端设备控制摄像头暂停转动并拍摄图像，实现了终端设备的智能全景拍摄，如此可以提升终端设备拍摄全景图像的灵活性和便捷性。
需要说明的是，以上以终端设备在步骤202之前执行步骤205和步骤206为例示例性的说明，可以理解，本公开实施例包括但不限于上述执行顺序，由于本公开实施例中终端设备在控制摄像头暂停转动后，控制摄像头继续转动，因此终端设备还可以在步骤202之后执行步骤205和步骤206。
可选的，结合图4，如图9所示，在上述的步骤200之前，本公开实施例提供的全景拍摄方法还包括下述的步骤207和步骤208。
步骤207、终端设备接收用户对第一人脸图像的第二输入。
其中，该第一人脸图像可以为预先存储的图像或者取景框中显示的预览图像。
本公开实施例中，上述第一人脸图像可以为终端设备的图库中存储的图像，也可以为终端设备的相机应用的取景框中显示的预览图像，还可以为终端设备根据图库中的多个图像筛选得出的人脸图像，或者可以为其它任意满足实际使用需求的输入，具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，上述用户的第二输入可以为点击输入(例如单击输入或双击输入)，也可以为滑动输入，还可以是其它任意可能形式的输入，具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，用户对终端设备的图库中的图像的选择输入，或者可以为用户对终端设备的相机应用的取景框中的图像的选择输入，或者可以为用户对终端设备根据图库中的多个图像筛选得出的人脸图像的选择输入。
步骤208、终端设备响应于第二输入，将第一人脸图像对应的人脸特征信息确定为预设人脸特征信息。
本公开实施例中，在用户对第一人脸图像进行第二输入之后，终端设备可以对该第一人脸图像进行图像分析，获得该第一人脸图像包含的人脸特征信息，并将该人脸特征信息确定为预设人脸特征信息。进一步的，在全景拍摄过程中，终端设备可以识别摄像头采集到的图像中是否包含预设人脸特征信息，在识别到图像中包含预设人脸特征信息的情况下，终端设备控制摄像头暂停转动，以执行拍摄操作。
通过本方案，当用户拍摄趣味全景照片时，无需人为地转动终端设备，避免终端设备位移对最终全景图像效果产生影响。终端设备控制摄像头自动转动并捕捉目标对象，无需目标对象每次移动固定角度，目标对象可以以任意顺序移动任意角度进行拍摄，避免了每次移动固定角度的操作难度。
可选的，本公开实施例中，在终端设备识别到目标对象之后，终端设备可以提示用户即将开始拍摄。终端设备提示的方式可以为：通过闪光灯提示；通过摄像头上或终端设备背部的彩色灯光提示；通过语音提示等。具体可以根据实际使用需求确定，本公开实施例不作限定。
举例来说，以通过彩色灯光提示为例：(1)在摄像头转动并识别到目标对象，调焦完成之后，终端设备控制彩色灯亮绿色以提示用户；(2)若检测到用户距离终端设备太远，则终端设备控制彩色灯亮黄色提示(其中，用户与终端设备的距离越远，灯点亮的颜色越偏向紫色)；若终端设备检测到用户距离设备太近，则终端设备控制彩色灯亮灰色提示(其中，用户与终端设备的距离越近，灯点亮的颜色越偏向黑色；若检测到用户与终端设备的距离适中，则终端设备控制彩色灯亮绿色；(3)当倒计时将要拍摄时，则终端设备控制彩色灯亮绿色(或红色)闪烁提示，并且闪烁频率随着时间的减少而增加；(4)在拍摄完成之后，终端设备控制彩色灯亮蓝色(例如长亮)以提示用户拍摄完成。
示例性的，以趣味全景拍摄为例，在全景拍摄过程中，摄像头从起始位置开始以逆时针方向识别目标对象，在识别到目标对象之后，摄像头暂停转动(即固定不动)，亮绿灯提示，3秒后指示灯闪烁5秒提示开始拍摄，拍摄完成后亮蓝灯5秒待用户到下一个拍摄点。摄像头继续逆时针转动识别目标对象，继续拍摄直至拍摄过程结束。
通过该方案，在拍摄全景图像过程中，无需用户对终端设备进行操作，通过灯的颜色或语音等提示用户接下来的行为，单人即可完成拍摄，如此简化了趣味全景拍摄的复杂程度，单人即可拍出效果较好的趣味全景图像。
第二实现方式
可选的，结合图2，如图10所示，在上述的步骤202之前，本公开实施例提供的全景拍摄方法还包括下述的步骤209。
步骤209、在摄像头每次转动过程中，终端设备控制摄像头转动预设角度，并控制摄像头暂停转动。
可选的，本公开实施例中，上述预设角度可以为10度，或者可以为20度，或者可以为30度，或者可以为其它任意满足实际使用需求的角度，具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，终端设备可以控制摄像头沿第一方向依次转动N次，并在摄像头每次转动过程中，终端设备检测摄像头转动的角度是否等于预设角度。在终端设备检测到摄像头转动的角度等于预设角度的情况下，终端设备控制摄像头暂停转动，并且在摄像头每次暂停转动之后，拍摄得到一个图像。如此，在终端设备控制摄像头沿第一方向依次转动N次之后，终端设备最终可以得到N个图像。进一步的，终端设备可以将拍摄得到的N个图像拼接成目标全景图像。
具体的，在用户触发终端设备启用全景拍摄功能之后，终端设备可以控制摄像头转动到拍摄起始位置(假设摄像头顺时针转动，那么拍摄起始位置可以为摄像头顺时针转动的起点)。在摄像头转动到拍摄起始位置之后，终端设备可以提示用户终端设备已经就绪。然后，在预设时长(可以是几秒，也可以是几十秒)之后，终端设备可以提示用户将要开始拍摄。在拍摄得到一个图像之后，终端设备可以控制摄像头转动预设角度，并在摄像头暂停转动后，终端设备提示用户将要开始拍摄。如此循环，直至摄像头转动N次，拍摄得到N个图像。在确定拍摄过程结束的情况下，终端设备将拍摄得到的N个图像拼接成趣味全景图像。
通过本方案，在拍摄全景图像过程中，无需用户人为地对终端设备进行操作，实现终端设备对全景拍摄的智能控制，从而可以避免设备位移对最终全景图像效果产生影响。
可选的，本公开实施例中，终端设备提示用户的方式可以为：通过闪光灯提示；通过摄像头上或终端设备背部的彩色灯光提示；通过语音提示等。当然，终端设备提示用户的方式还可以为其它任意满足实际使用需求的方式，具体可以根据实际使用需求确定，本公开实施例不作限定。
举例来说，以通过彩色灯光提示为例：(1)当摄像头转动到相应位置并就绪以后，亮绿色提示用户；(2)倒计时将要拍摄时，亮绿色(或红色)闪烁提示，并且闪烁频率随着时间的减少而增加；(3)拍摄完成后以蓝色常亮提示用户拍摄完成。
通过该方案，在拍摄全景图像过程中，无需用户对终端设备进行操作，通过灯的颜色或语音等提示用户接下来的行为，单人即可完成拍摄，如此简化了趣味全景拍摄的复杂程度，单人即可拍出效果较好的趣味全景图像。
需要说明的是，以上以终端设备在步骤202之前执行步骤209为例示例性的说明，可以理解，本公开实施例包括但不限于上述执行顺序，由于本公开实施例中终端设备在控制 摄像头暂停转动后，控制摄像头继续转动，因此终端设备还可以在步骤202之后执行步骤209。
可选的，在摄像头每次转动过程中，不管是在通过摄像头识别到目标对象的情况下终端设备控制摄像头暂停转动，还是在摄像头转动预设角度的情况下终端设备控制摄像头暂停转动，在摄像头每次暂停转动之后，终端设备可以输出提示信息，以提示用户即将自动拍摄，或者提示用户在调整位置后拍摄。
示例性的，结合图10，如图11所示，在上述的步骤209之后，本公开实施例提供的全景拍摄方法还包括下述的步骤210。
步骤210、终端设备输出第一提示信息或第二提示信息。
其中，上述第一提示信息可以用于指示目标距离不在预设距离范围内，上述第二提示信息可以用于指示目标距离在预设距离范围内且将在预设时长之后执行拍摄操作。其中，目标距离为所识别的对象与终端设备之间的距离。
可选的，本公开实施例中，上述第一提示信息可以通过语音提示，或者可以通过闪光灯提示，或者可以通过彩色指示灯提示。第二提示信息与第一提示信息的提示方式可以相同，也可以不同。
示例性的，以通过彩色指示灯提示第一提示信息和第二提示信息为例，假设终端设备设置有彩色指示灯，那么上述步骤210具体可以通过下述的步骤210a或步骤210b实现。
步骤210a、在输出第一提示信息的情况下，终端设备控制指示灯在第一预设时长内，以第一颜色持续发光，该第一颜色用于指示目标距离不在预设距离范围内。
在终端设备输出第一提示信息的情况下，用户可以通过第一提示信息获知如何调整目标对象与终端设备之间的距离以及方位关系，以提升终端设备在拍摄全景图像时采集图像的准确性。
步骤210b、在输出第二提示信息的情况下，终端设备控制指示灯在第二预设时长内，以第二颜色持续发光，该第二颜色用于指示目标距离在预设距离范围内且调焦完成；并控制指示灯在第三预设时长内，以第三颜色闪烁发光，该第三颜色用于指示第三时长后将执行拍摄操作；且在执行拍摄操作之后，控制指示灯在第四预设时长内，以第四颜色持续发光，该第四颜色用于指示拍摄完成。
