相关申请的交叉引用
本申请要求在2021年11月01日提交中国国家知识产权局、申请号为202111282790.3、申请名称为“一种图像拍摄方法与相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种图像拍摄方法与相关设备。
背景技术
用户对图像拍摄要求越来越高，比如，用户旅行时，期望将沿途景物的全貌进行拍摄。为了满足用户需求，部分电子设备(比如手机)具有全景拍摄功能，全景拍摄功能用于拍摄具有大视角(angle of view，FOV)的图像，即一张图像上可以包括更多拍摄对象。
一般，电子设备上设置有广角摄像头，该广角摄像头用于拍摄全景图像。然而，广角摄像头的图像解析能力(即摄像头分辨率)较弱，所以广角摄像头拍摄的全景图像虽然包含了更多景物，但是图像细节不够清楚，影响拍摄体验。
发明内容
本申请提供了一种图像拍摄方法与相关设备，用于提升图像拍摄体验。
第一方面，提供一种图像拍摄方法。该方法适用于电子设备。电子设备上包括第一摄像头和第二摄像头，所述方法包括：响应于第一操作，显示拍摄界面，所述拍摄界面中显示第一图像，所述第一图像为所述第一摄像头采集的图像；响应于第二操作，拍摄得到第二图像，所述第二图像是基于所述第一图像和第三图像得到的，所述第三图像是所述第二摄像头拍摄的，且所述第三图像与所述第一图像上存在重叠区域，所述重叠区域内包括至少一个相同对象；其中，所述第二摄像头拍摄所述第三图像时使用的第二拍摄参数与所述第一摄像头拍摄所述第一图像时使用的第一拍摄参数相关。
也就是说，电子设备上的第一摄像头采集了第一图像，第二摄像头采集了第三图像，且第三图像与第二图像上有重叠区域，通过第三图像与第一图像得到第二图像，比如，将第三图像与第一图像融合得到第二图像，这样第二图像的图像质量比第一图像有提升，可以提升拍摄体验。进一步地，由于第二摄像头拍摄第三图像时的第二拍摄参数与第一摄像头拍摄第一图像时的第一拍摄参数相关，所以第三图像与第一图像能够更高的融合，进一步的提升第二图像的图像质量。
在一种可能的设计中，所述第一摄像头是广角摄像头，所述第二摄像头是长焦摄像头。
一般，广角摄像头的图像解析能力(即摄像头分辨率)较弱，所以广角摄像头拍摄的全景图像虽然包含了更多景物，但是图像清晰度较低，而长焦摄像头的图像解析能力(即摄像头分辨率)较强，所以长焦摄像头采集的图像的清晰度较高。本申请实施例中，电子设备基于长焦摄像头采集的图像(第三图像)与广角摄像头拍摄的全景图像(即第一图像) 得到第二图像，这样的话，第二图像上既可以具有大视角，也可以具有较高的清晰度。
在一种可能的设计中，所述第一拍摄参数包括：第一曝光时间、第一光圈数、第一感光度、第一白平衡、第一物距、第一焦距中的至少一种；和/或，所述第二拍摄参数包括：第二曝光时间、第二光圈数、第二感光度、第二白平衡、第二物距、第二焦距中的至少一种。需要说明的是，此处是对拍摄参数的举例，还可以包括更多或更少的参数，比如饱和度、色温、滤镜等等，只要第二拍摄参数与第一拍摄参数相关即可。
在一种可能的设计中，所述第二摄像头拍摄与所述第一拍摄参数相关，包括如下至少一项：
所述第二白平衡度与所述第一白平衡度之间的差值小于第一阈值；
所述第二焦距与所述第一焦距之间的差值小于第二阈值；
所述第二物距与所述第一物距之间的差值小于第三阈值；
所述第一曝光时间、所述第一感光度以及所述第一光圈数与所述第二曝光时间、所述第二感光度以及所述第二光圈数满足预设函数关系。
需要说明的是，由于第二摄像头拍摄第三图像时的第二拍摄参数与第一摄像头拍摄第一图像时的第一拍摄参数相关，所以第三图像与第一图像能够更高的融合，可以提升第二图像的图像质量。
在一种可能的设计中，所述预设函数关系，包括：
Figure PCTCN2022126806-appb-000001
其中，S1为所述第一感光度，T1为所述第一曝光时间，A1为所述第一光圈数，所述A2为所述第二光圈数，S2为所述第二感光度，T2为所述第二曝光时间。
在一种可能的设计中，电子设备响应于第二操作，拍摄得到第二图像，包括：响应于第二操作，确定所述第一图像上的第一区域；调整所述第二摄像头的拍摄角度，使得所述第一区域内的拍摄对象处于所述第二摄像头的视角范围内，并拍摄得到第三图像；在所述第一图像上基于所述第一图像和所述第三图像得到所述第二图像。也就是说，电子设备得到第一图像之后，确定第一图像上的第一区域，对第一区域进行细节拍摄，得到第三图像，基于第三图像和第一图像得到第二图像。这种方式所得到的第二图像上对第一区域作了细节补充，第一区域的清晰度提升。
示例性的，所述第一区域满足如下至少一种：
所述第一图像上用户感兴趣的拍摄对象所在区域；
所述第一图像的中心区域；
用户设定的区域；
所述第一图像上清晰度低于预设清晰度的区域。
因此，本申请实施例中，电子设备得到第一图像之后，可以对第一图像上用户感兴趣对应所在区域、用户设定的区域等进行细节拍摄，以补充这些区域的清晰度。这样，用户关注的区域的清晰度提升，有助于提升拍摄体验。
在一种可能的设计中，电子设备响应于第二操作，拍摄得到第二图像，包括：响应于第二操作，在所述第一图像上显示N个拍摄指示点，N为正整数；调整所述第二摄像头的拍摄角度，使得所述N个拍摄指示点中第一拍摄指示点所在区域内的拍摄对象处于所述第二摄像头的视角范围内，并拍摄得到第三图像；检测到用于指示拍摄的第三操作时，基于 所述第一图像和所述第三图像得到所述第二图像。也就是说，电子设备在第一图像上显示N个拍摄指示点，用户可以对其中部分拍摄指示点所在区域内的拍摄对象进行拍摄，以补充这部分拍摄指示点所在区域的细节清晰度。
在一种可能的设计中，电子设备响应于第二操作，拍摄得到第二图像，包括：响应于第二操作，在所述第一图像上显示N个拍摄指示点，N为正整数；依次调整所述第二摄像头的拍摄角度，使得所述第二摄像头对每个拍摄指示点所在区域内的拍摄对象进行拍摄，得到N张第三图像；检测到对所有拍摄指示点均拍摄完成时，基于所述N张第三图像与所述第一图像得到所述第二图像。也就是说，电子设备在第一图像上显示N个拍摄指示点，电子设备可以分别对每个拍摄指示点所在区域内的拍摄对象进行拍摄，得到N张第三图像，基于N张第三图像和第一图像得到第二图像。
在一种可能的设计中，所述拍摄指示点的数量与所述第一拍摄参数和/或所述第二拍摄参数相关；其中，所述拍摄指示点的数量包括在水平方向上的数量和/或在竖直方向上的数量。
比如，所述拍摄指示点的数量与所述第一拍摄参数和/或所述第二拍摄参数相关，包括：在所述水平方向上所述拍摄指示点的数量k1与所述第一摄像头在水平方向上的视角范围与所述第二摄像头在水平方向上的视角范围的比值相关。
示例性的，在所述水平方向上所述拍摄指示点的数量k1满足：
Figure PCTCN2022126806-appb-000002
其中，W1为所述第一摄像头对应的成像平面的宽度，f1为所述第一摄像头的焦距，W2为所述第二摄像头对应的成像平面的宽度，f2为所述第一摄像头的焦距。
再比如，所述拍摄指示点的数量与所述第一拍摄参数和/或所述第二拍摄参数相关，包括：在所述竖直方向上所述拍摄指示点的数量k2与所述第一摄像头在竖直方向上的视角范围与所述第二摄像头在竖直方向上的视角范围的比值相关。
示例性的，在所述竖直方向上所述拍摄指示点的数量k2满足：
Figure PCTCN2022126806-appb-000003
其中，h1为所述第一摄像头对应的成像平面的高度，f1为所述第一摄像头的焦距，h2为所述第二摄像头对应的成像平面的高度，f2为所述第一摄像头的焦距。
需要说明的是，由于水平方向上拍摄指示点的数量k1与第一摄像头在水平方向上的视角范围与第二摄像头在水平方向上的视角范围的比值相关，如果每个拍摄指示点对应一个区域(该区域的中心点为拍摄指示点)，那么在水平方向上对应k1个区域，这k1个区域能够完全覆盖第一图像的宽度(即水平宽度)，如果对每个区域均进行细节补充，那么能够保证对第一摄像头采集的第一图像的水平方向上的所有区域均进行细节补充。同理，由于竖直方向上拍摄指示点的数量k2与第一摄像头在竖直方向上的视角范围与第二摄像头在竖直方向上的视角范围的比值相关，如果每个拍摄指示点对应一个区域(该区域的中心点为拍摄指示点)，那么在竖直方向上对应k2个区域，这k2个区域能够完全覆盖第一图像的高度(即竖直高度)，如果对每个区域均进行细节补充，那么能够保证对第一摄像 头采集的第一图像的竖直方向上的所有区域均进行细节补充。这样，可以避免第一图像上存在部分区域没有经过细节补充，导致图像完整性差。
第二方面，提供一种图像拍摄方法，应用于包括第一电子设备和第二电子设备的系统，所述方法包括：所述第一电子设备响应于第一操作，显示拍摄界面，所述拍摄界面中显示第一图像，所述第一图像为所述第二电子设备上的第一摄像头采集的图像；所述第一电子设备响应于第二操作，通过所述第一电子设备上的第二摄像头拍摄得到第三图像，所述第三图像与所述第一图像上存在重叠区域，所述重叠区域内包括至少一个相同对象；其中，所述第二摄像头拍摄所述第三图像时使用的第二拍摄参数与所述第一摄像头拍摄所述第一图像时使用的第一拍摄参数相关；所述第一电子设备基于所述第三图像和所述第一图像得到第二图像；或者，所述第一电子设备基于所述第三图像和所述第一图像得到第二图像后将所述第二图像发送给所述第二电子设备。
在一种可能的设计中，所述第一拍摄参数包括：第一曝光时间、第一光圈数、第一感光度、第一白平衡、第一物距、第一焦距中的至少一种；和/或，
所述第二拍摄参数包括：第二曝光时间、第二光圈数、第二感光度、第二白平衡、第二物距、第二焦距中的至少一种。

系统为例，示例性说明电子设备100的软件结构。在一些实施例中，将
Figure PCTCN2022126806-appb-000008
系统分为五层，从上至下分别为应用程序层，应用程序框架层，安卓运行时(Android runtime)和系统库，内核层以及硬件层。
如图2所示，应用程序层可以包括一系列应用程序包。比如相机，图库，日历，通话，地图，导航，WLAN，蓝牙，音乐，视频等应用程序。
应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。如图2所示，应用程序框架层可以包括窗口管理器，内容提供器，视图系统，电话管理器，资源管理器，通知管理器等。窗口管理器用于管理窗口程序。窗口管理器可以获取显示屏大小，判断是否有状态栏，锁定屏幕，截取屏幕等。内容提供器用来存放和获取数据，并使这些数据可以被应用程序访问。所述数据可以包括视频，图像，音频，拨打和接听的电话，浏览历史和书签，电话簿等。视图系统包括可视控件，例如显示文字的控件，显示图片的控件等。视图系统可用于构建应用程序。显示界面可以由一个或多个视图组成的。例如，包括短信通知图标的显示界面，可以包括显示文字的视图以及显示图片的视图。电话管理器用于提供电子设备100的通信功能。例如通话状态的管理(包括接通，挂断等)。资源管理器为应用程序提供各种资源，比如本地化字符串，图标，图片，布局文件，视频文件等等。通知管理器使应用程序可以在状态栏中显示通知信息，可以用于传达告知类型的消息，可以短暂停留后自动消失，无需用户交互。比如通知管理器被用于告知下载完成，消息提醒等。通知管理器还可以是以图表或者滚动条文本形式出现在系统顶部状态栏的通知，例如后台运行的应用程序的通知，还可以是以对话窗口形式出现在屏幕上的通知。例如在状态栏提示文本信息，发出提示音，电子设备振动，指示灯闪烁等。
Android Runtime包括核心库和虚拟机。Android runtime负责安卓系统的调度和管理。核心库包含两部分：一部分是java语言需要调用的功能函数，另一部分是安卓的核心库。应用程序层和应用程序框架层运行在虚拟机中。虚拟机将应用程序层和应用程序框架层的java文件执行为二进制文件。虚拟机用于执行对象生命周期的管理，堆栈管理，线程管理，安全和异常的管理，以及垃圾回收等功能。

为了便于理解，本申请以下实施例将以电子设备是手机为例，结合附图对本申请实施例提供的图像拍摄方法进行具体阐述。
图3中的(a)示出了手机的一种图形用户界面(graphical user interface，GUI)，该GUI为手机的桌面201。桌面201中包括各种应用(application，APP)的图标，其中包括相机应用的图标202。当手机检测到针对相机应用的图标202的操作(比如点击操作)后，可以启动相机应用，显示如图3中的(b)所示的另一GUI，该GUI可以称为拍摄界面203。在预览状态下，该取景界面203内可以实时显示预览图像。示例性的，图3中的(b)中拍摄界面203中显示图像A。图像A以风景图为例，包括船只等拍摄对象。
继续参见图3中的(b)，取景界面203中包括用于指示拍照模式的控件204，用于指示录像模式的控件205，用于指示全景模式的控件206，以及拍摄控件207。图3中的(b)以手机当前正处于拍照模式为例，在拍照模式下，当手机检测到针对拍摄控件207的操作后，手机执行拍照操作。假设手机检测到针对录像控件206的操作，则进入录像模式，在录像模式下，手机检测到针对拍摄控件207的操作后，手机执行录像操作(该过程图中未示出)。当手机检测到针对全景控件206的操作时，进入全景模式，显示如图3中的(c)所示的拍摄界面，该拍摄界面中显示图像B。图像B比图像A具有更大的视角(angle of view，FOV)。比如，图像B中除了包括图像A中已有的拍摄对象(如船只)以外，还包括树、狗等更多的拍摄对象。对比图3中的(b)和图3中的(c)可知，手机从拍照模式切换到全景模式时，拍摄界面中的预览图像由图像A切换为图像B，切换为视角更大的图像。为了方便描述，下文将图像B称为第一图像。
在一些实施例中，第一图像是第一摄像头拍摄的图像。示例性的，所述第一摄像头可以是广角摄像头。
在一些实施例中，当手机显示图3中的(c)所示的界面时，若手机检测到针对拍摄控件207的操作，执行拍照动作，得到一张全景图像，该全景图像即广角摄像头拍摄的图像。这种方式比较便捷，但是由于广角摄像头的图像解析能力(即摄像头分辨率)较弱，所以广角摄像头拍摄的全景图像虽然包含了更多景物，但是图像细节不够清楚。
为了提升广角摄像头拍摄的全景图像的细节清晰度，本申请实施例提供一种图像拍摄方法，该方法可以对广角摄像头拍摄的全景图像作细节补充，以提升全景图像的细节清晰度。比如，除了广角摄像头拍摄的全景图像以外，电子设备还拍摄了细节图，通过将细节图与广角摄像头所拍摄的全景图像融合的方式得到细节清晰度增强的全景图像。
示例性的，电子设备上具有至少两个摄像头，比如，第一摄像头和第二摄像头。其中，第一摄像头用于采集第一图像(即全景图像)，第二摄像头用于采集第二图像(用于对全 景图像作细节补充的细节图)。其中，第一摄像头可以是广角摄像头。考虑到第二图像用于做细节补充，所以尽量保证第二图像上细节清晰度较高，所以第二摄像头可以使用图像解析力(即摄像头分辨率)较强的摄像头，比如，第二摄像头的分辨率高于第一摄像头的分辨率，如，第二摄像头可以是长焦摄像头，当然也可以是其他类型摄像头。
一种可实现方式为，当手机显示图3中的(c)所示的界面时，若手机检测到针对拍摄控件207的操作时，显示如图4所示的界面400。该界面400中显示第一图像(即图像B)，以及四个拍摄指示点：拍摄指示点402、拍摄指示点403、拍摄指示点404、拍摄指示点405。其中，拍摄指示点用于提示用户将第二摄像头对准拍摄指示点进行细节图的拍摄。需要说明的是，此处提到的对准拍摄指示点进行拍摄可以理解为，调整第二摄像头的拍摄角度使得拍摄指示点所在区域内的拍摄对象处于第二摄像头的视角范围内。比如，以拍摄指示点402为例，拍摄指示点402所在区域是以拍摄指示点402为中心、长度为预设长度、宽度为预设宽度的区域1(如后面的图7中的区域1)，即调整第二摄像头的拍摄参数使得区域1内的拍摄对象处于第二摄像头的视角范围内。其中，预设长度、预设宽度等具体取值本申请不限定。为了方便指导用户操作，界面400中还可以显示提示信息：对准拍摄指示点进行拍摄。
为了方便提示用户是否对准拍摄指示点，界面400中还包括基准点401。基准点401的显示位置随着第二摄像头拍摄角度的变化而变化。用户通过基准点401判断是否对准拍摄指示点。比如，当基准点401与某个拍摄指示点位置重叠或者覆盖于该拍摄指示点上层时，认为对准了该拍摄指示点。示例性的，基准点401与拍摄指示点的形状、颜色等可以相同或不同。
示例性的，如图5中的(a)，手机检测到基准点401对准拍摄指示点402时，通过第二摄像头拍摄图像1。一些实施例中，当手机检测到基准点401对准拍摄指示点402并保持对准状态预设时长时，通过第二摄像头拍摄图像1；或者，手机检测到基准点401对准拍摄指示点402并且检测到用户操作(比如单击或双击基准点401的操作)时，通过第二摄像头拍摄图像1。需要说明的是，图5中的(a)中手机检测到基准点401对准拍摄指示点402并拍摄图像1，可以是手机后台拍摄图像1，前台不展示拍摄的图像1，即在界面400中不出现图像1。由于前台不出现图像1，所以用户无法获知是否对拍摄指示点402拍摄完成。在一些实施例中，手机拍摄完图像1时，可以输出提示，以提示用户对拍摄指示点402拍摄完成。所述提示可以是声音、振动。或者，如图6所示，手机检测到基准点401对准拍摄指示点402并进行拍摄时，在基准点401上显示拍摄进度指示。所述拍摄进度指示可以是指示针600。指示针600从0度到360度进行旋转，代表拍摄进度。当旋转到360度时，代表拍摄完成。总之，手机前台可以不展示拍摄的细节图(即图像1)，但是可以通过一定的提示信息向用户提示对拍摄指示点402的细节图拍摄完成。
对拍摄指示点402拍摄完成之后，手机可以自动调整基准点401对准下一个拍摄指示点(比如拍摄指示点403)或者用户改变第二摄像头的拍摄角度以使基准点401对准下一个拍摄指示点。如图5中的(b)，手机检测到基准点401对准拍摄指示点403时，通过第二摄像头拍摄图像2。其中，手机对拍摄指示点403的拍摄过程与对拍摄指示点402的拍摄过程原理相同，不重叠赘述。以此类推，手机可以对剩余的拍摄指示点进行拍摄。比如，如图5中的(c)，手机检测到基准点401对准拍摄指示点404时，通过第二摄像头拍摄图像3。如图5中的(d)，手机检测到基准点401对准拍摄指示点405时，拍摄图像4。也 就是说，第二摄像头对四个拍摄指示点分别拍摄了对应的细节图，即图像1至图像4。
在一些实施例中，手机检测到遍历完四个拍摄指示点后，将四张图像(图像1至图像4)分别与第一图像融合得到第二图像。具体地，手机将四张图像分别融合到第一图像上对应区域内。比如，请参见图7，第一图像上包括四个区域，区域1至区域4。区域1的中心点为拍摄指示点402所在位置，区域2的中心点为拍摄指示点403所在位置，区域3的中心点为拍摄指示点404所在位置，区域4的中心点为拍摄指示点405所在位置。由于图像1是与区域1对应的细节图，所以手机将图像1融合到区域1中，即将图像1与区域1内的图像块融合，同理，将图像2融合到区域2中，将图像3融合到区域3中，将图像4融合到区域4中。需要说明的是，在图3中的(c)中，用户点击了一次拍摄按键207，然后进入图4或图5所示的界面400进行细节图的拍摄。当手机检测到遍历完四个拍摄指示点时，可以自动将四张图像(图像1至图像4)和第一图像融合得到第二图像。也就是说，只需用户点击一次拍摄按键207，即可拍摄得到一张细节清楚的全景图。
在另一些实施例中，在图3中的(c)中，用户点击了一次拍摄按键207，然后进入图4或图5所示的界面400进行细节图的拍摄。在遍历完四个拍摄指示点时，若手机检测到用户再次触发拍摄按键207时，将四张图像(即图像1至图像4)和第一图像融合得到第二图像。这种方式，需要用户点击两次拍摄按键207完成全景拍摄。一种可能的场景为，手机已遍历完四个拍摄指示点，但是在检测到用户再次触发拍摄按键207之前，不会将四张图像与第一图像融合，可以允许用户对其中某个拍摄指示点进行重新拍摄。比如，手机检测到基准点401再次对准拍摄指示点402时拍摄图像5，将图像5替换图像1。当手机检测到用户再次触发拍摄按键207时，将四张图像(图像2至图像5)与第一图像融合得到第二图像。
在一些实施例中，四个拍摄指示点中不需要全部遍历完。比如，只对拍摄指示点402和拍摄指示点403进行拍摄，得到两张细节图(即图像1和图像2)，将这两张图像与第一图像融合得到第二图像。一种可实现方式为，在图3中的(c)中，用户点击了一次拍摄按键207，然后进入图4的界面400，用户将基准点401对准拍摄指示点402拍摄得到图像1，将基准点401对准拍摄指示点403拍摄得到图像2。此时，手机检测到用户再次触发拍摄按键207，则将图像1和图像2分别与第一图像融合得到第二图像。该过程中，并未对拍摄指示点404与拍摄指示点405进行拍摄。这种方式中，用户可以只对关心的区域作细节补充。比如，如图5中的(d)，第一图像上用户只关心狗所在区域的拍摄质量，那么可以只对拍摄指示点404进行细节拍摄，这样不仅工作量可以降低，而且不影响用户拍摄体验，因为用户关心的部分的细节清晰度已提升。
在上面的实施例中，以手机通过第二摄像头对四个拍摄指示点分别进行拍摄为例。在另一些实施例中，手机还可以使用不同摄像头分别对四个拍摄指示点进行拍摄。比如，请参见图8，手机背面(与手机显示屏相对的一面)上设置有五个摄像头，其中摄像头1是广角摄像头(即第一摄像头)，用于采集第一图像。摄像头2至摄像头5可以是长焦摄像头或其他类型摄像头。摄像头2至摄像头5分别用于对不同的拍摄指示点进行拍摄。比如图像1可以是摄像头2拍摄的，图像2可以是摄像头3拍摄的，图像3可以是摄像头4拍摄的，图像4可以是摄像头5拍摄的。或者，图像1和图像2是摄像头2拍摄的，图像3和图像4是摄像头3拍摄的，等等，本申请实施例不作限定。
在上面的实施例中，手机显示拍摄提示点，通过拍摄指示点指示用户进行细节图的拍 摄。在另一些实施例中，手机也可以不显示拍摄指示点。比如，当手机显示图3(c)所示的界面时，若手机检测到针对拍摄控件207的操作时，手机后台确定第一图像上的第一区域，该第一区域为第一图像上待补充细节的区域。在确定第一区域之后，手机调整第二摄像头的拍摄角度使得第一区域内的拍摄对象处于第二摄像头的拍摄范围内，并通过第二摄像头拍摄第三图像，该第三图像即用于对第一区域作细节补充的细节图。手机将第三图像融入第一图像上第一区域内得到第二图像。该第二图像是全景图像但是细节清晰度高于第一图像。这种方式中，用户点击了拍摄控件207之后，手机未显示拍摄提示点，而是自动识别第一区域，并对第一区域作细节图(即第三图像)拍摄，将第三图像融合到第一图像的第一区域内得到第二图像。也就是说，用户点击一次拍摄控件207即自动得到细节清晰度较高的全景图像。
示例性的，第一区域可以是第一图像上用户感兴趣的拍摄对象所在区域。比如，手机可以记录用户对哪些拍摄对象修图过以及对每个拍摄对象修图的次数，那么用户感兴趣的拍摄对象可以是修图次数大于预设次数的对象。或者，手机中存储多张图像，其中包含某一拍摄对象(比如狗)的图像的数量大于预设数量，那么该拍摄对象即用户感兴趣拍摄对象。
或者，第一区域是第一图像上清晰度低于预设清晰度的区域。
或者，第一区域是第一图像的中心区域。
或者，第一区域也可以是用户设定的区域。比如，用户可以在图3中的(c)所示的界面中画圈操作选定第一区域。这种方式中，用户可以指定第一图像上哪个区域需要做细节补充，提升用户关心的区域内的细节清晰度。
在一些实施例中，第一区域可以是一个区域或多个区域。以两个区域，即第一区域和第二区域为例，手机调整第二摄像头的拍摄角度对第一区域进行拍摄得到第三图像，然后调整第二摄像头的拍摄角度对第二区域进行拍摄得到第四图像，然后将第三图像融合到第一图像上的第一区域内，将第四图像融合到第一图像上的第二区域内，得到第二图像。
如前文所述，手机通过第二摄像头拍摄细节图。可以理解的是，第二摄像头拍摄的图像质量与第二摄像头的拍摄参数相关，所述拍摄参数可以包括感光度、快门速度、焦距、物距、白平衡度、亮度、色温等中的至少一种。本申请实施例提供如下至少一种确定第二摄像头的拍摄参数的方式。
第一种方式，第二摄像头的拍摄参数是默认设置好的(比如默认是初始值)，或者，是上一次设置使用时设置的。比如，用户上一次使用第二摄像头时设置的拍摄参数包括感光度50，快门速度1/250秒，那么第二摄像头对拍摄指示点拍摄时，使用感光度50，快门速度1/250秒进行拍摄。
第二种方式，第二摄像头的第二拍摄参数与第一摄像头的第一拍摄参数相关。其中，所述第一拍摄参数包括：第一曝光时间、第一光圈数、第一感光度、第一白平衡、第一物距、第一焦距中的至少一种。所述第二拍摄参数包括：第二曝光时间、第二光圈数、第二感光度、第二白平衡、第二物距、第二焦距中的至少一种。
示例性的，所述第二摄像头拍摄与所述第一拍摄参数相关，包括如下至少一项：
所述第二白平衡度与所述第一白平衡度之间的差值小于第一阈值。比如，第一摄像头的第一白平衡为6000K，那么第二摄像头的第二白平衡度为6000K。
所述第二焦距与所述第一焦距之间的差值小于第二阈值。比如，第一摄像头的第一物距为100m，那么，第二摄像头的物距为100m。
所述第二物距与所述第一物距之间的差值小于第三阈值。
所述第一曝光时间、所述第一感光度以及所述第一光圈数与所述第二曝光时间、所述第二感光度以及所述第二光圈数满足预设函数关系。
示例性的，所述预设函数关系，包括：
Figure PCTCN2022126806-appb-000009
其中，S1为所述第一感光度，T1为所述第一曝光时间，A1为所述第一光圈数，所述A2为所述第二光圈数，S2为所述第二感光度，T2为所述第二曝光时间。
一般情况下，摄像头的光圈是已知的，即第二摄像头的第二光圈数A2和第一摄像头的第一光圈数A1是已知的，在已知第一摄像头的第一快门时间T1和第一感光度S1的情况下，通过上述公式(1)可以得到第二摄像头的第二感光度S2与第二快门时间T2的乘积，进而分别得到第二感光度S2与第二快门时间T2的取值。举例来说，假设第一摄像头的第一拍摄参数包括：第一感光度为100，第一快门速度(即第一曝光时间)为1/2000，第一光圈数为1.8，即A1＝1.8、S1＝100、T1＝1/2000。再假设第二摄像头的第二光圈数为3.5。那么，通过上述公式(1)可以计算出，S2T2＝0.189。示例性的，可以取S2＝50，T2＝1/250，只要S2与T2的乘积等于0.189即可。
需要说明的是，上述公式(1)可以是存储于手机中的，或者可以通过如下步骤1至步骤3得到。
步骤1，在拍摄图像时，曝光时间满足如下公式(2)：
Figure PCTCN2022126806-appb-000010
其中，A为光圈数，T为快门时间，L为景物亮度，S为感光度，K为反光式测光表校正常数，是一个常数。上述曝光时间所满足的公式(2)是已知的，比如ISO协议(ISO2720:1974)中给出的。
步骤2，因为公式(2)中L是固定值，K是固定值，所以上述公式(2)可以简化为下面的公式(3)：
Figure PCTCN2022126806-appb-000011
其中M为常数，
Figure PCTCN2022126806-appb-000012
步骤3，对于每个镜头都满足上述的公式(3)，那么不同镜头之间满足如下公式(1)：
Figure PCTCN2022126806-appb-000013
因此，通过以上的步骤1至步骤3得到上面的公式(1)。
在第二种方式中，由于第二摄像头的第二拍摄参数与第一摄像头拍摄第一图像时的第一拍摄参数相关，所以第二摄像头拍摄出的细节图与第一图像适配，比如，色彩、亮度等差异不大。这样细节图(比如图像1至图像4)与第一图像融合时，能够很好的融合。
第三种方式，第二摄像头的拍摄参数还可以是用户设置的，换言之，用户可调整。比如，请参见图9中的(a)，当基准点401对准拍摄指示点402时，在第一图像上显示拍摄参数900(比如，光圈50，快门速度1/250秒)。拍摄参数900是第二摄像头当前拍摄参数。用户可以增加或降低光圈或快门速度，比如通过“+”按键来增加，通过“-”按键来降低，第二摄像头使用调整后的拍摄参数对拍摄指示点402进行拍摄。同理，如图9中的(b)，在 基准点401对准拍摄指示点403时，显示拍摄参数901，用户可以调整该拍摄参数901，第二摄像头使用调整后的拍摄参数对拍摄指示点403进行拍摄。同理，如图9中的(c)，在基准点401对准拍摄指示点404时，显示拍摄参数902，用户可以调整该拍摄参数。如图9中的(d)，在基准点401对准拍摄指示点405时，显示拍摄参数903，用户可以调整该拍摄参数。
值得说明的是，以图4中的四个拍摄指示点为例，如果第二摄像头对四个拍摄指示点拍摄时使用的拍摄参数不同，那么对四个拍摄指示点所拍摄出的图像(即图像1至图像4)之间可能存在亮度、色彩等的明显差异。如果将所述四张图像与第一图像上不同区域(如图7)融合，那么融合之后的图像上不同区域的亮度、色彩等存在较大差异，影响图像整体的美感。因此，在本申请实施例中，第二摄像头对每个拍摄指示点拍摄时使用的第二拍摄参数可以相同。比如，所述第二拍摄参数是经过上述第一种至第三种方式中的任一种确定的。
在上面的实施例中，以四个拍摄指示点为例，需要说明的是，本申请实施例不限定拍摄指示点的数量，可以是至少一个。比如，拍摄指示点的数量可以是系统默认设置的或者用户设置的，或者拍摄指示点的数量与第一摄像头的第一拍摄参数和/或第二摄像头的第二拍摄参数相关。其中，拍摄指示点的数量包括在水平方向上的数量和/或在竖直方向上的数量。
示例性的，所述拍摄指示点在水平方向上的数量满足：
Figure PCTCN2022126806-appb-000014
其中，W1为所述第一摄像头对应的成像平面的宽度，f1为所述第一摄像头的焦距，W2为所述第二摄像头对应的成像平面的宽度，f2为所述第一摄像头的焦距。比如，第一摄像头的焦距为27mm，即f1＝27mm，第二摄像头的焦距为95mm，即f2＝95mm，两个摄像头的成像平面大小相同，宽w为36mm，高h为24mm，那么通过上面的公式(4)可以得到k1＝3.33，通过向上取整的方式可知在水平方向上需要4个拍摄提示点。
示例性的，所述拍摄指示点在竖直方向上的数量满足：
Figure PCTCN2022126806-appb-000015
其中，h1为第一摄像头对应的成像平面的高度，f1为第一摄像头的焦距，h2为第二摄像头对应的成像平面的高度，f2为第二摄像头的焦距。比如，第一摄像头的焦距为27mm，即f1＝27mm，第二摄像头的焦距为95mm，即f2＝95mm，两个摄像头的成像平面大小相同，宽w为36mm，高h为24mm，那么通过上面的公式(5)可以得到k2＝3.33，通过向上取整的方式可知在竖直方向上需要4个拍摄提示点。
也就是说，拍摄指示点包括水平方向4个，竖直方向4个的4*4的矩阵，如图4所示。
在一些实施例中，上面的公式(4)和(5)可以事先存储在手机中，或者通过如下步骤得到：
步骤1，基于摄像头的成像原理可知，第一摄像头在水平方向上的视角大小α11满足如 下公式(6)：
Figure PCTCN2022126806-appb-000016
其中，f1是第一摄像头的焦距，w1是第一摄像头的成像平面在水平方向上的尺寸即宽度。
第一摄像头在竖直方向上的视角大小α12满足如下公式(7)：
Figure PCTCN2022126806-appb-000017
其中，f1是第一摄像头的焦距，h1是第一摄像头的成像平面在竖直方向上的尺寸即高度。
为了方便理解，请参见图10A，为第一摄像头与成像平面之间的关系示意图。经过第一摄像头的光线在该平面上形成图像。可以理解的是，第一摄像头的视角α1包括在水平方向上视角α11，竖直方向上的视角α12。α11对应成像平面的宽度w1，α12对应成像平面的高度h1。其中，α11、w1与焦距f1满足上述公式(6)，α12、h1与焦距f1满足上述公式(7)。
同理，第二摄像头在水平方向上的视角大小α21满足如下公式(8)：
Figure PCTCN2022126806-appb-000018
其中，f2是第二摄像头的焦距，w2是第二摄像头的成像平面在水平方向上的尺寸即宽度。
第二摄像头在竖直方向上的视角大小α22满足如下公式(9)：
Figure PCTCN2022126806-appb-000019
其中，f2是第二摄像头的焦距，h2是第二摄像头的成像平面在竖直方向上的尺寸即高度。
为了方便理解，请参见图10B，为第二摄像头与成像平面之间的关系示意图。经过第二摄像头的光线在该平面上形成图像。可以理解的是，第一摄像头的视角α2包括在水平方向上视角α21，竖直方向上的视角α22。α21对应成像平面的宽度w2，α22对应成像平面的高度h2。其中，α21、w2与焦距f2满足上述公式(8)，α22、h2与焦距f2满足上述公式(9)。
步骤2，拍摄指示点在水平方向上的数量k1与第一摄像头在水平方向上的视角α11和第二摄像头在水平方向上的视角α21的比值相关。比如，水平方向上的拍摄指示点的个数满足如下公式：
Figure PCTCN2022126806-appb-000020
因此，通过上述方式得到公式(4)。
拍摄指示点在竖直方向上的数量k2与第一摄像头在竖直方向上的视角α12和第二摄像头在竖直方向上的视角α22的比值相关。比如，竖直方向上拍摄指示点的个数为：
Figure PCTCN2022126806-appb-000021
因此，通过上述方式得到公式(5)。
在上面的实施例中，通过公式(4)计算水平方向上的拍摄指示点的数量，通过公式(5)计算竖直方向上的拍摄指示点的数量。在另一些实施例中，当通过公式(4)确定出水平方向上的拍摄指示点的数量之后，竖直方向上的拍摄指示点数量等于水平方向上的拍摄指示点数量即可，或者，当通过公式(5)确定竖直方向上的拍摄指示点的数量之后，水平方向上的拍摄指示点的数量等于竖直方向上的拍摄指示点的数量即可。
在其它实施例中，拍摄指示点的数量还可以是用户设置的或者系统默认设置的等等，本申请实施例不作限定。
在确定拍摄指示点在水平方向上的数量以及在竖直方向上的数量之后，可以确定拍摄指示点的位置，比如，均匀分布于第一图像上。示例性的，所述均匀分布可以理解为在水平方向上各个拍摄指示点之间的距离相同，在竖直方向上各个拍摄指示点之间的距离相同。比如，请参见图11，在水平方向上，各个拍摄指示点之间的距离均为L1，在竖直方向上各个拍摄指示点之间的距离均为L2。
图12为本申请一实施例提供的图像拍摄方法的流程示意图。如图所示，该方法的流程包括：
S1201，电子设备响应于第一操作，显示拍摄界面，所述拍摄界面中显示第一图像，所述第一图像为所述第一摄像头采集的图像。

示例性的，所述第二操作可以是在图3中的(c)中，用户点击拍摄按键207的操作。
其中，第二摄像头的视角范围与第一摄像头的视角范围有重叠，所以第二摄像头采集的第二图像与第一摄像头采集的第一图像上有重叠区域，重叠区域内包括至少一个相同对象。比如，重复区域可以是图7中区域1至区域4中的任一区域。这样，第二图像上的重叠区域与第一图像上的重叠区域可以融合，以提升第一图像上该重叠区域的清晰度。
一种可实现方式为，在图3中的(c)中，用户点击了一次拍摄按键207(即第二操作)，然后进入图4或图5所示的界面400，通过对拍摄指示点进行细节图的拍摄，得到四张图像(图像1至图像4)。当手机检测到遍历完四个拍摄指示点时，可以自动将四张图像(图像1至图像4)和第一图像融合得到第二图像。也就是说，只需用户点击一次拍摄按键207，即可拍摄得到一张细节清楚的全景图。这部分的具体实现过程可以参见前文描述。
另一种可实现方式为，在图3中的(c)中，用户点击了一次拍摄按键207(即第二操作)，然后进入图4或图5所示的界面400进行细节图的拍摄。在遍历完四个拍摄指示点或者不需要全部遍历完只对其中部分拍摄指示点进行拍摄，在手机检测到用户再次触发拍摄按键207时，将得到的细节图与第一图像融合得到第二图像。这部分的具体实现过程请参见前文描述。
又一种可实现方式为，电子设备也可以不显示拍摄指示点。比如，当显示图3中的(c)所示的界面时，若检测到针对拍摄控件207的操作(即第二操作)时，后台确定第一图像上的第一区域，该第一区域为第一图像上待补充细节的区域。在确定第一区域之后，手机调整第二摄像头的拍摄角度使得第一区域内的拍摄对象处于第二摄像头的拍摄范围内，并通过第二摄像头拍摄第三图像，该第三图像即用于对第一区域作细节补充的细节图。手机将第三图像融入第一图像上第一区域内得到第二图像。该第二图像是全景图像但是细节清晰度高于第一图像。这部分的具体实现过程请参见前文描述。
在本申请实施例中，第二摄像头拍摄第三图像时使用的第二拍摄参数与第一摄像头拍摄第一图像时使用的第一拍摄参数相关。其中，所述第一拍摄参数包括：第一曝光时间、第一光圈数、第一感光度、第一白平衡、第一物距、第一焦距中的至少一种。所述第二拍摄参数包括：第二曝光时间、第二光圈数、第二感光度、第二白平衡、第二物距、第二焦距中的至少一种。

所述第二焦距与所述第一焦距之间的差值小于第二阈值。比如，所述第二焦距等于所述第一焦距。
所述第二物距与所述第一物距之间的差值小于第三阈值。比如，所述第二物距等于所述第一物距。
所述第一曝光时间、所述第一感光度以及所述第一光圈数与所述第二曝光时间、所述第二感光度以及所述第二光圈数满足预设函数关系。所述预设函数关系，即前文中的公式(1)，关于公式(1)的推导过程，请参见前文，为了节省篇幅，不重复赘述。
本申请实施例提供的图像拍摄方法还可以适用于系统。该系统中包括第一电子设备和第二电子设备。第一电子设备用于拍摄第一图像(即全景图像)，第二电子设备用于拍摄第二图像，第二图像是用于对第一图像作细节补充的细节图，比如上面的实施例中图像1至图像4。第二电子设备拍摄的第二图像与第一电子设备拍摄的第一图像融合得到细节清晰的全景图像。其中，第一摄像头可以是广角摄像头。第二摄像头的分辨率高于第一摄像头的分辨率，如，第二摄像头可以是长焦摄像头，当然也可以是其它类型的摄像头。
其中，第一电子设备与第二电子设备可以是相同类型的设备，比如都是手机；或者，也可以是不同类型的设备，比如一个是手机，另一个是平板电脑、无人机等等。
为了方面描述，以第一电子设备是无人机、第二电子设备是手机为例。
在一些实施例中，手机与无人机建立连接，所述连接包括无线连接，具体的连接过程本文不多赘述。手机与无人机连接之后，无人机向手机发送无人机上第一摄像头采集的图像。示例性的，无人机上或者与无人机连接的遥控设备上设置用于向手机发送图像的按键 等，用户可以通过该按键控制无人机将采集的图像发送给手机。所述第一摄像头可以广角摄像头。
请参见图13中的(a)，手机进入全景模式之后，显示图像C，图像C是手机上广角摄像头拍摄的图像，还显示标记1300。一些实施例中，当手机与无人机连接时或者手机接收到无人机的图像时，可以出现标记1300。当手机检测到标记1300时，显示如图13中的(b)所述的拍摄界面，该拍摄界面中包括图像D，图像D是无人机拍摄的图像。也就是说，手机在拍摄界面中展示无人机拍摄的图像。为了方便描述，将图像D称为第一图像。
当手机检测到针对拍摄控件207的操作时，显示如图14的界面1400，该界面1400中显示第一图像(即图像D)，还显示基准点1401以及四个拍摄指示点(拍摄指示点1402至拍摄指示点1405)。手机通过第二摄像头依次对四个拍摄指示点进行拍摄得到四张图像。其中，第二摄像头的第二拍摄参数与无人机上第一摄像头的第一拍摄参数相关。具体的实现过程与前文相同，此处不重复赘述。
手机得到四张细节图之后可以将其发送给无人机，无人机将这四张图像与无人机本机拍摄的第一图像融合得到一张细节清晰的全景图像。或者，手机将这四张图像与无人机本机拍摄的第一图像融合得到一张细节清晰的全景图像之后，将该全景图像发送给无人机。

另一种可实现方式为，在图13中的(b)中，用户点击了一次拍摄按键207(即第二操作)，然后进入图14所示的界面1400进行细节图的拍摄。在遍历完四个拍摄指示点或者不需要全部遍历完只对其中部分拍摄指示点进行拍摄，在检测到用户再次触发拍摄按键207时，得到的第三图像(可以是一张或多张)。这部分的具体实现过程请参见前文描述。
又一种可实现方式为，手机也可以不显示拍摄指示点。比如，当显示图13中的(b)所示的界面时，若检测到针对拍摄控件207的操作(即第二操作)时，后台确定第一图像上的第一区域。在确定第一区域之后，手机调整第二摄像头的拍摄角度使得第一区域内的拍摄对象处于第二摄像头的拍摄范围内，并通过第二摄像头拍摄第三图像，该第三图像即用于对第一区域作细节补充的细节图。这部分的具体实现过程请参见前文描述。
在本申请实施例中，第二摄像头拍摄第三图像时使用的第二拍摄参数与第一摄像头拍摄第一图像时使用的第一拍摄参数相关。其中，所述第一拍摄参数包括：第一曝光时间、第一光圈数、第一感光度、第一白平衡、第一物距、第一焦距中的至少一种。所述第二拍摄参数包括：第二曝光时间、第二光圈数、第二感光度、第二白平衡、第二物距、第二焦距中的至少一种。

所述第一曝光时间、所述第一感光度以及所述第一光圈数与所述第二曝光时间、所述第二感光度以及所述第二光圈数满足预设函数关系。所述预设函数关系，即前文中的公式(1)，关于公式(1)的推导过程，请参见前文，为了节省篇幅，不重复赘述。
S1505，第二电子设备向第一电子设备发送第三图像。
S1506，第一电子设备基于第三图像和第一图像得到第二图像。
在另一些实施例中，S1505可以替换成：第二电子设备基于第三图像和第一图像得到第二图像。S1506可以替换成：第二电子设备将第二图像发送给第一电子设备。
需要说明的是，为了节省篇幅，该实施例的各种实现方式不重复赘述，前文中的各种实现方式(比如拍摄指示点的数量和/或位置的确定)均可以应用于该实施例中。
