在步骤403中，在每个旋转指令发送后，通过摄像头组件采集旋转后的图像。
在步骤404中，根据采集到的若干个图像生成全景图片。
综上所述，本公开实施例提供的全景拍摄方法，在检测到启动全景拍摄时，通过摄像头组件在起始角度位置采集图像并向旋转组件依次发送至少一个旋 转指令，旋转指令用于指示旋转组件按照指定的旋转方向和旋转角度进行旋转，在每个旋转指令发送后，通过摄像头组件采集旋转后的图像，根据采集到的若干个图像生成全景图片；解决了在同时使用终端设备的前置摄像头和后置摄像头采集图像合成全景图片时，由于前置摄像头的像素较低而造成的全景图片的图像质量较低的问题；由于全景拍摄终端中的处理器是通过指示旋转组件驱动摄像头组件进行旋转并采集图像，根据由同一个摄像头组件在不同的角度位置采集到的若干个图像生成全景图片的，达到了可以仅使用一个像素较高的摄像头组件就能生成图像质量较高的全景图片的效果。
图5是根据一示例性实施例示出的一种全景拍摄方法的流程图，该方法应用于图1A或图1B所示的全景拍摄终端中，该方法可以由图1A或图1B所示的全景拍摄终端中的处理器来实现；或者，该方法应用于如图3所示的全景拍摄系统中，该方法可以由放置在图2所示的旋转组件上的控制终端来实现。该方法包括如下几个步骤：
在步骤501中，在检测到启动全景拍摄时，通过摄像头组件在起始角度位置采集图像。
用户可以在全景拍摄终端或控制终端的相机应用中选择进入全景拍摄模式，当处于全景拍摄模式，且处理器检测到存在作用于拍摄按钮的按键操作时，启动全景拍摄。
其中，起始角度位置是终端设备在启动全景拍摄时，摄像头组件正对的角度位置。
在步骤502中，向旋转组件发送第i个旋转指令。
其中，旋转指令用于指示旋转组件按照指定的旋转方向和旋转角度进行旋转，旋转组件用于驱动摄像头组件旋转，旋转组件用于根据接收到的第i个旋转指令驱动摄像头组件按照旋转方向旋转旋转角度至第i个角度位置，i为正整数，i的起始值为1。
可选的，旋转指令中包括旋转方向字段和旋转角度字段，旋转指令中的旋转方向字段用于指示旋转方向，旋转指令中的旋转角度字段用于指示旋转角度。旋转组件对旋转指令进行解析得到旋转方向字段和旋转角度字段，根据旋转方向字段确定旋转方向，根据旋转角度字段确定旋转角度。比如，旋转组件对旋转指令解析得到旋转方向字段为right，旋转角度字段为30，则表示向右旋转 30度。
可选的，旋转指令中包括具有预定格式的旋转角度字段，该具有预定格式的旋转角度字段用于指示旋转方向和旋转角度，预定格式包括符号和数字中的至少一种。旋转组件对旋转指令进行解析得到具有预定格式的旋转角度字段，根据具有预定格式的旋转角度字段确定旋转方向和旋转角度。比如，旋转组件对旋转指令解析得到的具有预定格式的旋转角度字段为+30，则表示向右旋转30度，再比如，旋转组件对旋转指令解析得到的具有预定格式的旋转角度字段为-50，则表示向左旋转50度。
第i个旋转指令用于指示的旋转方向和旋转角度是旋转组件驱动摄像头组件从第i-1个角度位置旋转至第i个角度位置的旋转方向和旋转角度，可选的，不同的旋转指令用于指示的旋转方向和旋转角度相同或者不同，本公开实施例以每个旋转指令指示的旋转方向和旋转角度均相同为例进行说明。需要说明的是，第0个角度位置即为起始角度位置。
在步骤503中，在每个旋转指令发送后，通过摄像头组件采集旋转后的图像。
其中，旋转后的图像是摄像头组件在旋转组件的驱动下进行旋转后所采集的图像。
该步骤可以通过以下两种实现方式中的任意一种实现方式来实现：
在第一种可能的实现方式中，在每个旋转指令发送后，当达到预定时间间隔时，通过摄像头组件采集旋转后的图像。
其中，预定时间间隔为系统预设值或由用户自定义。
在另一种可能的实现方式中，在每个旋转指令发送后，当接收到旋转组件返回的反馈信号时，通过摄像头组件采集旋转后的图像。
当旋转组件根据旋转指令进行旋转后，旋转组件向处理器返回反馈信号，处理器在接收到反馈信号后，确定摄像头组件已经在旋转组件的驱动下旋转至第i个角度位置，则控制摄像头组件采集图像，采集到的图像即为第i个角度位置的图像。
在步骤504中，检测总旋转角度是否达到全景角度。
其中，总旋转角度是第i个角度位置相对于起始角度位置所旋转的角度，全景角度是启动全景拍摄拍摄全景图片时，全景图片所覆盖的角度范围，全景角度为系统预设值或由用户自定义。可选的，全景角度是360度。
在步骤505中，在总旋转角度小于全景角度时，则令i＝i+1，再次执行向旋转组件发送第i个旋转指令的步骤。
在步骤506中，若总旋转角度达到全景角度，根据采集到的若干个图像生成全景图片。
当总旋转角度达到全景角度时，处理器结束全景拍摄并根据采集图像的顺序对采集到的若干个图像进行拼接，在对第i-1个图像和第i个图像进行拼接时，包括如下几个步骤：
1、对第i-1个图像和第i个图像进行图像预处理，图像预处理包括图像去噪、图像直方图均衡中的至少一种。可选的，当摄像头组件为鱼眼镜头时，图像预处理还包括畸变校正。
2、提取第i-1个图像和第i个图像的图像特征，图像特征包括特征点、特征轮廓和特征曲线中的至少一种，常见的特征点包括SIFT(Scale-invariant feature transform，尺度不变特征变换)、FAST(Features fromaccelerated segment test)和SURF(Speeded Up Robust Features)中的至少一种。
3、将第i个图像与第i-1个图像进行拼接，并将第i-1个图像中与第i个图像的图像特征相同的图像特征部分丢弃，或者，将第i个图像中与第i-1个图像的图像特征相同的图像特征部分丢弃，直至生成完整的全景图片。
需要说明的是，当全景角度为360度，且总旋转角度达到全景角度时，终端设备的第i个角度位置与起始角度位置是相同的角度位置，终端设备在第i个角度位置采集到的图像与在起始角度位置采集到的图像可能是相同，则为了避免生成的全景图片中存在重复的部分，终端设备可以不使用在起始角度位置采集到的图像，而使用在第1个角度位置、第2个角度位置…第i个角度位置所采集到的i个图像生成全景图片。
需要说明的是，当图1A或图1B所示的全景拍摄终端中包括至少两个摄像头组件时，或者，当放置于图2所示的旋转组件上的控制终端中包括至少两个摄像头组件时，向旋转组件发送每个旋转指令后，可以同时通过每个摄像头组件采集图像，也可以仅通过其中部分摄像头组件采集图像，本公开实施例以同时通过每个摄像头组件采集图像为例进行说明。
则该步骤可以包括如下两个步骤：
1、对于至少两个摄像头组件中的每个摄像头组件，根据摄像头组件采集到的若干个图像拼接得到与摄像头组件对应的显示图片。
使用上述三个步骤示出的方法将根据摄像头组件采集到的若干个图像拼接得到与摄像头组件对应的显示图片。
2、根据每个摄像头组件所对应的显示图片拼接得到全景图片。
对于每两个相邻设置的摄像头组件所对应的显示图片，提取这两个显示图片的图像特征，将这两个显示图片进行拼接。将两个全景图片进行拼接的方法可以结合上述将第i-1个图像和第i个图像进行拼接的方法，本实施例对此不再赘述。
需要说明的是，在实际实现时，也可以是在接收到在检测到结束全景拍摄时，根据采集到的若干个图像生成全景图片。比如，当用户在相机应用中选择结束全景模式时，结束全景拍摄并根据采集到的若干个图像生成全景图片。
综上所述，本公开实施例提供的全景拍摄方法，在检测到启动全景拍摄时，通过摄像头组件在起始角度位置采集图像并向旋转组件依次发送至少一个旋转指令，旋转指令用于指示旋转组件按照指定的旋转方向和旋转角度进行旋转，在每个旋转指令发送后，通过摄像头组件采集旋转后的图像，根据采集到的若干个图像生成全景图片；解决了在同时使用终端设备的前置摄像头和后置摄像头采集图像合成全景图片时，由于前置摄像头的像素较低而造成的全景图片的图像质量较低的问题；由于全景拍摄终端中的处理器是通过指示旋转组件驱动摄像头组件进行旋转并采集图像，根据由同一个摄像头组件在不同的角度位置采集到的若干个图像生成全景图片的，达到了可以仅使用一个像素较高的摄像头组件就能生成图像质量较高的全景图片的效果。
本公开实施例提供的全景拍摄方法，摄像头组件在处理器或控制终端的驱动下进行旋转，避免了由用户旋转终端设备中的摄像头组件进行旋转时因抖动、旋转角度太大/太小、位置偏移等导致的生成的全景图片的图片质量较差的问题，达到了提高生成的全景图片的图像质量的效果。
本公开实施例提供的全景拍摄方法，可以仅使用一个摄像头组件，且对于摄像头组件的FOV没有限制，扩大了该全景拍摄方法的适用范围。
本公开实施例提供的全景拍摄方法，全景拍摄终端或控制终端中可以包括至少两个摄像头组件，达到了可以通过多个摄像头组件采集更多不同角度位置的图像，生成显示范围更广的全景图片的效果。
在一个示例性的例子中，以上述全景拍摄方法用于图1A所示的全景拍摄 终端10中为例，全景拍摄终端10中的摄像头组件进行全景拍摄时的俯视示意图如图6所示。假设全景拍摄终端10中的处理器向旋转组件依次发送的若干个旋转指令用于指示的旋转方向均为向右旋转，指示的旋转角度均为90度，且全景角度为360度。
处理器启动全景拍摄时，在起始角度位置601采集图像，如图6中的(a)所示，并向旋转组件发送第1个旋转指令，旋转组件根据第1个旋转指令驱动摄像头组件向右旋转90度至第1个角度位置602后向处理器发送反馈信号，处理器在接收到反馈信号后，通过摄像头组件在第1个角度位置602处采集图像，如图6中的(b)所示。
处理器检测总旋转角度为90度小于全景角度，向旋转组件发送第2个旋转指令，旋转组件根据第2个旋转指令驱动摄像头组件向右旋转90度至第2个角度位置603后向处理器发送反馈信号，处理器在接收到反馈信号后，通过摄像头组件在第2个角度位置603处采集图像，如图6中的(c)所示。
处理器检测总旋转角度为180度小于全景角度，向旋转组件发送第3个旋转指令，旋转组件根据第3个旋转指令驱动摄像头组件向右旋转90度至第3个角度位置604后向处理器发送反馈信号，处理器在接收到反馈信号后，通过摄像头组件在第3个角度位置604处采集图像，如图6中的(d)所示。
处理器检测总旋转角度为270度小于全景角度，向旋转组件发送第4个旋转指令，旋转组件根据第4个旋转指令驱动摄像头组件向右旋转90度至第4个角度位置605后向处理器发送反馈信号，处理器在接收到反馈信号后，通过摄像头组件在第4个角度位置605处采集图像，如图6中的(e)所示。此时处理器检测到总旋转角度为360，则结束全景拍摄并将在第1个角度位置602、第2个角度位置603、第3个角度位置604和第4个角度位置605处采集到的4个图像合成为全景图片。
需要说明的是，图6中将摄像头组件在进行全景拍摄时所处的(a)、(b)、(c)、(d)和(e)的五个状态在不同的显示图中进行显示，但是实际实现时，摄像头组件都是绕着同一个旋转轴61进行旋转的。
可选的，基于图5所示的实施例，全景拍摄终端的处理器通过内部电路向旋转组件发送的旋转指令，或者，控制终端向旋转组件发送的旋转指令用于指示的旋转角度是由处理器根据摄像头组件的FOV确定的，则该方法还包括如 下几个步骤，如图7所示：
在步骤701中，确定摄像头组件的FOV。
可选的，摄像头组件的FOV包括在全景拍摄终端或控制终端的配置信息中，全景拍摄终端的处理器或者控制终端通过查询配置信息确定摄像头组件的FOV。
在步骤702中，根据FOV确定旋转角度，旋转角度小于或等于FOV。
该步骤至少存在以下两种可能的实现方式：
在第一种可能的实现方式中，将摄像头组件的FOV确定为旋转角度。
在第二种可能的实现方式中，当摄像头组件的FOV不能被全景角度整除时，若将摄像头组件的FOV确定为旋转角度，则在总旋转角度达到全景角度时，旋转组件驱动摄像头组件进行旋转的次数不是整数次。比如，全景角度为360度，摄像头组件的FOV为100度，若确定旋转角度为100度，则旋转组件需要驱动摄像头组件进行3.6次旋转使总旋转角度达到360度，并不合理。此时，可以使用以下几个步骤确定旋转角度：
1、将全景角度和FOV的商确定为旋转次数。
2、对旋转次数执行向上取整得到调整后的旋转次数。
3、将全景角度和调整后的旋转次数的商确定为旋转角度。
在上述示例性的例子中，旋转次数为全景角度和FOV的商，即旋转次数为360/100＝3.6次，将旋转次数向上取整得到调整后的旋转次数为4次，确定旋转角度为全景角度和调整后的旋转次数的商，即旋转角度为360/4＝90度。
综上所述，本公开实施例提供的全景拍摄方法，根据摄像头组件的FOV确定旋转角度，在采集到生成全景图片所需的若干个图像的基础上，减少旋转次数和采集的图像的个数，优化了全景拍摄的流程。
可选的，在基于上述实施例的其他可选实施例中，上述步骤504-步骤506可被替代实现为如下步骤，如图8所示：
在步骤801中，检测旋转次数是否达到总旋转次数。
其中，总旋转次数是由全景角度与旋转角度的商所确定的次数，或者，总旋转次数是由全景角度与旋转角度的商执行向上取整后所确定的次数。
在步骤802中，若旋转次数小于总旋转次数，则令i＝i+1，再次执行向旋转组件发送第i个旋转指令的步骤。
在步骤803中，若总旋转角度达到全景角度，根据采集到的若干个图像生成全景图片。
可选的，在基于上述实施例的其他可选实施例中，上述步骤502-606可被替代实现为如下步骤，如图9所示：
在步骤901中，向旋转组件发送旋转指令。
其中，旋转指令用于指示旋转方向、旋转角度、旋转频率和总旋转次数，旋转指令用于指示旋转组件按照指定的旋转方向、旋转角度和旋转频率旋转指定的总旋转次数，旋转频率用于指示旋转组件进行的每两次旋转之间的时间间隔，总旋转次数的含义可以结合上述图8所示的实施例。
在步骤902中，当接收到旋转组件返回的反馈信号时，通过摄像头组件采集旋转后的图像。
旋转组件在完成每次旋转后，向全景拍摄终端的处理器返回反馈信号，或者，向控制终端返回反馈信号。
在步骤903中，根据采集到的若干个图像生成全景图片。
可选的，检测当前时刻与上一个采集图像的时刻之间的时间间隔是否达到预设时间间隔，当达到预设时间间隔时，结束全景拍摄并根据采集到的若干个图像生成全景图片，预设时间间隔是系统预设值或由用户自定义。
可选的，根据总旋转次数确定采集的总图像个数，总图像个数为总旋转次数加一所确定的个数，检测采集到的图像个数是否达到总图像个数，当达到总图像个数时，结束全景拍摄并根据采集到的若干个图像生成全景图片。
比如，在图6所示的示例性的例子中，全景拍摄终端的处理器向旋转组件发送的旋转指令用于指示的旋转方向为向右旋转，旋转角度为90度，旋转频率为10秒/次，旋转次数为4次，则总图像个数为5个。则旋转组件在驱动摄像头组件旋转至第1个角度位置602后，向处理器发送反馈信号，处理器接收到反馈信号后在第1个角度位置602处采集图像。
旋转组件在驱动摄像头组件旋转至第1个角度位置602后，经过10秒，驱动摄像头组件从第1个角度位置602继续旋转至第2个角度位置603，向处理器发送反馈信号，处理器接收到反馈信号后在第2个角度位置603处采集图像。
同理，旋转组件继续驱动摄像头组件旋转至第3个角度位置604和第4个 角度位置605后，也向处理器发送反馈信号，处理器继续在第3个角度位置604和第4个角度位置605处采集图像。当摄像头组件在旋转组件的驱动下旋转至第4个角度位置605处时，处理器检测到采集到的图像个数为6个，达到总图像个数，处理器结束全景拍摄并根据采集到的6个图像生成全景图片。
综上所述，本公开实施例提供的全景拍摄方法，向旋转组件发送一个旋转指令后，旋转组件根据该旋转指令旋转指定的总旋转次数，不需要每次都向旋转组件发送旋转指令，达到了减少与旋转组件之间的通信次数，减少功耗的效果。
