基于上述移动终端硬件结构、通信网络系统，以及示例技术中，一般都是采用其中一个摄像头输出图像，摄像头采集图像过程中可能基于摄像头的一些影响因素(如抖动)，导致瞬间采集的图像不清晰，此时经常需要重复拍摄多次的情况，或者，基于一个摄像头能够采集的范围有限，需要不断的调整拍摄位置才能够采集到用户想要采集的范围，容易错过瞬间 即逝的画面，影响拍照效果，提出本申请各个实施例。
第一实施例：
请参照图3，本申请提出拍照方法的第一实施例，包括以下步骤：
步骤S10，控制至少两个所述摄像头采集图像数据；
步骤S20，比对所述摄像头采集的图像数据的特征信息，确定特征信息优于其它摄像头采集的图像数据的特征信息的目标图像数据；
步骤S30，于所述移动终端的预览界面显示所述目标图像数据。
本实施例应用于移动终端，所述移动终端上设有至少两个摄像头，可选地，至少两个所述摄像头位于所述移动终端的同一屏幕的不同位置，如图4所示，所述摄像头11分布在所述显示屏1的水平方向上，所述摄像头11采集图像的位置不同，或者采集图像的视角不同，或者采集的视场范围不同。或者，如图5所示，至少两个所述摄像头11位于所述移动终端的不同屏幕上，移动终端的显示屏1包括主屏幕、副屏幕和侧屏幕，所述摄像头11设置在主屏幕和侧屏幕上，至少两个所述摄像头11可采集不同角度的图像。又或者，如图6所示，所述移动终端包括折叠屏1，所述折叠屏1具有至少两个可折叠的屏幕，至少两个所述摄像头11分别设置于两个所述屏幕上。可以理解的是，本实施例中移动终端为上述结构时，均能实现本实施例的拍照功能，以下以所述移动终端包括折叠屏，所述摄像头分别设置于折叠屏的可折叠的不同屏幕上为例进行说明。
移动终端在接收到拍照指令时，控制至少两个所述摄像头采集图像数据，两个所述摄像头采集图像数据，基于摄像头的位置不同、或者视角不同、或者视场范围不同，两个所述摄像头采集的图像数据不同，基于此，对比所述摄像头采集的图像数据的特征信息，确定特征信息优于其它摄像头采集的图像数据的特征信息的目标图像数据；然后于所述移动终端的预览界面显示所述目标图像数据。由至少两个摄像头采集图像(可选地，可以是同时采集，也可以不同时采集，如在预设较短时间内分别采集等，可选地，若不是同时采集，则触发采集的指令可以是同一个，也可以是多个)，增加采集到的图像效果更佳的图像数据的概率，从而减少某个摄像头受一些影响因素影响导致拍照效果不佳对本次拍照结果的影响。如此，用户可以快速获取到目标图像数据，进而快速拍摄图像，可以快速采集瞬间图像，然后基于至少两个摄像头分别采集到的数据进行比对后获得效果最佳的图像数据来生成图像，用户无需重复拍摄，且拍摄效果佳，提升拍照体验。
可选地，至少两个所述摄像头所采集的图像数据为不同视场范围的图像数据，或者为不同视角的图像数据，因此，每个所述摄像头采集的图像数据至少有部分不同，在一些实施例中，可以将摄像头采集的图像数据拼接以形成视场范围更广的图像，如应用在合照中，可以省去来回调整拍摄位置。
可选地，本实施例采用至少两个摄像头采集图像数据，通过选取显示效果更佳的目标图像数据来作为图片的原始数据，可以提高图片的显示效果。可选地基于各个所述摄像头所采集的图像数据的特征信息选取显示效果更佳的目标图像数据，可选地，所述图像数据的特征信息包括目标对象数量、目标对象位置、目标对象清晰度、目标对象亮度和图像分辨率中的至少一种。
可选地，目标图像数据的选取方式由多种，如所述比对所有所述摄像头采集的图像数据的特征信息，确定特征信息优于其它摄像头采集的图像数据的特征信息的目标图像数据的方 式包括以下至少一个：
(一)比对所有所述摄像头的图像数据中目标对象数量，将所述目标对象数量最多的图像数据确定为所述目标图像数据。
也即所述图像数据的特征信息为目标对象数量，如拍摄人时，根据人的数量来确定目标图像数据，尤其是大合照中，各个摄像头基于位置设置，能采集到的人数不同，本实施例将所述目标对象数量最多的摄像头采集到的图像数据作为所述目标图像数据，然后于预览界面上显示，如此，拍合照时，多个摄像头作用，提高获取全部目标对象的概率，实现不需要调整位置的情况下，也能够达到合照的目的，提高拍照效果。
(二)比对所有所述摄像头的图像数据中目标对象位置，将所述目标对象位置处于预览界面的预设位置的图像数据确定为所述目标图像数据；
可选地，所述图像数据的特征信息为目标对象位置，如所述目标对象相对于预览界面的显示位置。如所述目标对象为人时，识别所述目标对象所在的位置是否为预览界面的预设位置(中间位置，或者最佳显示位置如中间下两格位置等)，将目标对象位置处于预览界面的预设位置的图像数据作为目标图像数据，然后于预览界面进行显示，使得基于预览界面的预览数据形成的图片，使得人的显示效果更佳，提高拍照效果。
(三)比对所有所述摄像头的图像数据中目标对象清晰度，将所述目标对象清晰度最清晰的图像数据确定为所述目标图像数据。
可选地，所述图像数据的特征信息为目标对象清晰度，如所述目标对象为人时，通过识别各个所述摄像头采集的图像数据中人的清晰度，将最清晰的图像数据作为所述目标图像数据，使得所述目标图像数据于预览界面中显示时，达到清晰的显示效果，提高拍照效果。
(四)比对所有所述摄像头的图像数据中目标对象亮度，将所述目标对象亮度最亮的图像数据确定为所述目标图像数据。
可选地，所述图像数据的特征信息为目标对象亮度，如所述目标对象为人时，通过比对各个所述摄像头采集的图像数据中人的亮度，将亮度最亮的图像数据作为所述目标图像数据，如此，于所述预览界面中显示所述目标图像数据时，达到提亮目标对象的显示效果，提高拍照效果。
(五)比对所有所述摄像头的图像数据的图像分辨率，将图像分辨率最高的图像数据确定为所述目标图像数据。
可选地，所述图像数据的特征信息为图像数据的图像分辨率，通过比对各个所述摄像头采集的图像数据的分辨率，将分辨率最高的图像数据作为所述目标图像数据，于所述预览界面中显示所述目标图像数据时，所显示的图像数据的分辨率高，提高图像的显示效果，如此，达到更佳的拍照效果。
可选地，所述比对所述摄像头采集的图像数据的特征信息，确定特征信息优于其它摄像头采集的图像数据的特征信息的目标图像数据步骤中的特征信息可以基于由用户设定，或者还可以基于拍摄类型确定，如步骤S20之前，获取拍照类型，根据所述拍照类型确定特征信息，进而比对各个所述摄像头采集的图像数据的所述特征信息，以确定特征信息优于其它摄像头采集的图像数据的特征信息的目标图像数据。也即所述特征信息可以基于用户不同设定不同而不同，或者基于拍摄类型不同而不同，如此，不同的特征信息采用不同的方式获取所述目标图像数据。
如在拍摄类型为人物时，则赋予目标对象数量或目标对象位置的权重更高，优先通过比对各个所述摄像头的图像数据中的目标对象或目标对象位置，然后将所述目标对象数量最多的图像数据确定为所述目标图像数据；和/或将所述目标对象位置处于预览界面的预设位置的图像数据。由于拍摄人时，拍摄目的主要是为了显示人，因此基于目标对象数量和目标对象位置来确定目标图像数据，所获得的图像数据更满足用户需求，提高拍照效果。
如拍摄类型为景物，则赋予目标对象清晰度或图像分辨率等特征信息的权重更高，优先通过比对各个所述摄像头的图像数据中目标对象清晰度或图像分辨率等，将所述目标对象清晰度最清晰的图像数据确定为所述目标图像数据，和/或将图像分辨率最高的图像数据作为所述目标图像数据。由于景物的突显性与人物不同，通过获取清晰度更高，或者图像分辨率更高的图像，可以提高景物的显示效果，如此，提高景物的拍照效果。
本实施例基于拍摄类型不同对应的特征信息不同，或者基于用户的不同设定对应的特征信息不同，如此，在拍照过程中，可以基于不同需求对应获取更符合需求的图像数据作为目标图像数据，提高图像显示效果更佳的获取概率，提高拍照效果。
可选地，所述目标图像数据还可以结合上述目标对象数量、目标对象位置、目标对象清晰度、目标对象亮度和图像分辨率中的至少两个来确定。可选地，所述目标对象数量、目标对象位置、目标对象清晰度、目标对象亮度和图像分辨率对应设置有权重，基于权重大小优先确定目标图像数据。如目标对象数量对应的权重最大时，则以所述目标对象数量来确定目标图像数据，若以所述目标对象数量确定的目标图像数据包括多个时，则根据权重小于目标对象数量的特征信息来确定目标图像数据，如所述目标对象的位置的权重小于目标对象数量，则以所述目标对应的位置来确定目标图像数据。
可选地，所述特征信息对应的各个权重可以基于用户设定，或者基于用户使用习惯或大数据分析确定或生成，或者基于不同的拍摄场景不同而不同。
可选地，本实施例可应用于所有拍照模式中，也可以仅应用在合照模式和/或全景模式中。
本实施例中，在拍照时，控制至少两个所述摄像头采集图像数据；然后基于比对所述摄像头采集的图像数据的特征信息，确定特征信息优于其它摄像头采集的图像数据的特征信息的目标图像数据；于所述移动终端的预览界面显示所述目标图像数据。基于从至少两个摄像头采集的图像数据中选择更优的图像数据作为最终的显示图像，相对于只采用一个摄像头采集图像而言，本实施例可以避免一个摄像头采集图像不清楚则导致本次拍摄效果差的情况出现，本实施例的拍摄效果更佳。
第二实施例：
请参照图7，本实施例基于上述第一实施例，可选地，所述比对所有所述摄像头采集的图像数据的特征信息，确定特征信息优于其它摄像头采集的图像数据的特征信息的目标图像数据的步骤包括：
步骤S21，比对所有所述摄像头的图像数据中目标对象数量，可选地，所述特征信息包括目标对象数量；
步骤S22，判断所有所述图像数据中的目标对象数量是否一致；
若是，也即在所有所述图像数据中的目标对象数量一致时，执行步骤23，将显示特征优于其它摄像头采集的图像数据的显示特征的图像数据作为所述目标图像数据。
可选地，所述特征信息还可包括显示特征，可选地，所述显示特征包括目标对象的显示 位置、目标对象的显示清晰度、目标对象的显示亮度和图像分辨率中的至少一种。
本实施例中，所述特征信息包括目标对象数量，通过比对所有所述摄像头的图像数据中的目标对象数量，确定各个所述摄像头所采集的目标对象数量是否为一致的。如合照中，有10人合照时，通过识别目标对象数量确定各个摄像头所采集到的数量是否为10人，或者是否均为一个相同的数量。若是，则说明所有摄像头均把合照的人框选在画面中了，或者各个摄像头框选在画面中的人数一致，此时无法通过目标对象数量来确定用于最终显示的目标图像数据。
基于此，本实施例中的特征信息还可包括显示特征，如目标对象的显示位置、目标对象的显示清晰度、目标对象的显示亮度和图像分辨率中的至少一种。在通过目标对象数量无法获取目标图像数据时，通过所述显示特征确定目标图像数据。如基于目标对象的显示位置处于预览界面的预设位置的图像数据作为目标图像数据。或者如基于目标对象的显示清晰度最高的图像数据作为所述目标图像数据，或者基于目标对象显示亮度最亮或者图像分辨率最高的图像数据作为所述目标图像数据。
因此，本实施例基于目标对象数量结合显示特征确定目标图像数据，在满足目标对象数量要求的同时，使得目标对象的显示效果更佳。
可选地，若否，也即在所述目标对象数量不一致时，执行步骤S24，获取目标数量最多的目标图像数据；
步骤S25，识别所述目标图像数据和其它摄像头采集的其它图像数据的目标对象；
步骤S26，若具有所述其它图像数据中的目标对象与所述目标图像数据的目标对象不一致时，采用所述其它图像数据和所述目标图像数据合成后的图像数据更新所述目标图像数据。
需要说明的是，所述目标对象不一致是指目标图像数据中的目标对象与其它图像数据中的目标对象不一一对应，如目标图像数据中具有A成员、B成员和C成员，而其它图像数据中具有A成员和D成员，可选地，所述D成员为与所述目标图像数据不一致的目标对象。本实施例可通过人脸识别技术识别各个所述目标对象。
在合照过程中，若所述目标对象数量不一致，一般存在以下几种情况：
第一，至少一个摄像头采集的图像数据中包括所有合照人员，而至少一个摄像头采集的图像数据只包括部分合照人员(也即部分人员没有框选在画面中)。如10人合照，而一个摄像头的图像数据中包括10个人，而另一个摄像头的图像数据中包括7个人。
第二，所有摄像头采集的图像数据均只包含部分合照人员，各个所述摄像头所采集到的人数不同，且具有重叠的部分合照人。如10人合照，一摄像头采集到8个人，而另一个摄像头采集到7个人。
第三，所有摄像头采集的图像数据均只包含部分合照人员，各个所述摄像头所采集到的人数不同，且不不具有重叠的人。如10人合照，一摄像头采集到5个人，而另一个摄像头采集到另外5个人。
在一些可选实施例中，将目标对象数量最多的图像数据作为目标图像数据，以确保所拍摄的图像中包含的目标对象最多。
而在一些可选实施例中，为了进一步提高拍摄效果，使得更多甚至全部的目标对象均被拍摄在图像中，若比对各个所述摄像头采集的图像数据确定所述目标对象数量不一致时，启动人脸识别，识别除目标图像数据之外的其它摄像头采集的其它图像数据的目标对象与所述 目标图像数据中的目标对象是否一致，确定与所述目标图像数据中的目标对象不一致的其它对象，采用所述其它图像数据和所述目标图像数据合成后的图像数据更新所述目标图像数据。
在本实施例中，若目标对象数量不一致，目标对象数量最多的图像数据与其它图像数据对比，可能存在有部分目标对象没有框选到画面中，此时为了确保完成合照，将其它图像数据与所述目标图像数据拼接合并后，形成更完整的目标图像数据，使得于移动终端的预览界面中显示人数更全的合照，提高拍照效果。
第三实施例：
请参照图8，本实施例基于上述第二实施例，可选地，所述采用所述其它图像数据和所述目标图像数据合成后的图像数据更新所述目标图像数据的步骤包括：
步骤S261，获取所述其它图像数据中相对所述目标图像数据的非重合区域；
步骤S262，将所述非重合区域的图像数据拼接到所述目标图像数据对应的拼接位置；
步骤S263，将拼接后的图像数据作为所述目标图像数据。
在确定所述其它图像数据中具有与目标图像数据中的目标对象不同的其它对象时，则说明所述其它图像数据与所述目标图像数据之间存在非重叠区域。也即所述非重叠区域是指各个所述摄像头所采集到的图像数据中，数据内容不相同的区域。
扫描各个所述图像数据，以获得非重叠区域和重叠区域，所述重叠区域和非重叠区域之间的分界位置为所述拼接位置，然后对所述其它数据中的非重叠区域进行抠图处理，再将所述非重叠区域拼接到所述目标图像数据对应的所述拼接位置，完成图像数据的拼接，然后将拼接后的图像数据作为所述目标图像数据，于所述移动终端的预览界面显示。
可选地，将所述非重合区域的图像数据拼接到所述目标图像数据对应的拼接位置的步骤包括：
将所述非重合区域的图像数据与所述目标图像数据的拼接位置对齐；
调整所述目标图像数据和所述非重合区域的图像数据之间的拼接位置的图像特征，使得所述拼接位置的相似度大于或等于预设阈值。
为了使得拼接后的图像融合和自然，在拼接图像过程中，将所述非重叠区域的图像数据对齐到所述目标图像数据的对应位置后，调整所述拼接位置的图像纹理和/或色彩，使得所述拼接位置的相似度接近相似。
可选地，所述图像特征包括纹理和/或色彩中的至少一个，所述相似度基于纹理差异和/或色彩差异中的至少一个确定。所述纹理差异越小和/或所述色彩差异越小，所述拼接位置的相似度越大。
在一实施例中，所述相似度是基于所述拼接位置划分的至少一个点对应的色彩或纹理的差异值确定的，在所述拼接位置中具有达到预设数量的点对应的色彩或纹理的差异值小于预设差值，则判定所述拼接位置的相似度大于或等于所述预设阈值。
在一些实施例中，所述相似度是基于所述拼接位置划分的至少一个点对应的色彩和/或纹理的差异值的和确定的。如获取一摄像头对应的点的色彩和/或纹理与另一摄像头对应的点的色彩和/或纹理的差异值，把纹理差异和/或色彩差异这两个差异相加作为对比数值，如一摄像头的第i点和另一摄像头的第i点的纹理和/或图像色彩的绝对值差异值C＝|Ti1-Ti2|+|Ci1-Ci2|越小，相似度越相似。
具体调节过程中，根据色彩差异或纹理差异进行调整，如以目标图像数据中的色彩作 为基准，调整所述其它数据中的非重叠区域的色彩，使得所述目标图像数据的色彩和其它数据的非重叠区域的色彩的差值最小化；或者，以目标图像数据中的纹理作为基准，调整所述其它数据中的非重叠区域的纹理，使得所述目标图像数据的纹理和其它数据的非重叠区域的纹理的差值最小化，实现图像拼接。
可选地，调整所述目标图像数据和所述非重合区域的图像数据之间的拼接位置的图像特征后，融合所述拼接位置。如对所述拼接位置进行自然过渡融合处理，使得非重叠区域与所述目标图像数据融合，提高图像的显示效果。
本实施例基于将其它摄像头采集的图像数据中与目标图像数据非重叠区域拼接到所述目标图像数据中，使得预览界面显示的图像数据的显示视角更广，提高合照的拍照效果。
第四实施例：
请参照图9，本实施例基于上述所有实时，所述于所述移动终端的预览界面显示所述目标图像数据的步骤之后，还可包括：
步骤S40，识别所述预览界面的预设位置的目标对象；
步骤S50，在所述预设位置的目标对象不完整时，输出调整提示信息。
可选地，所述预设位置可以为边缘位置，或其他位置。
可选地，所述调整提示信息包括旋转所述移动终端的折叠屏的折叠角度的提示信息，和/或调整移动终端位置的提示信息。
以所述目标对象为人为例进行说明：
为了避免人的部分身体未框选入所述预览界面，导致部分人只采集到部分身体，影响拍照效果，本实施例基于上述各个实施例形成所述目标图像数据，并于所述移动终端的预览界面显示所述目标图像数据后，识别所述预览界面的预设位置的目标对象(一般是位于预览界面边缘处的目标对象存在只采集到部分位置)，若识别到所述预设位置的目标对象不完整时，输出调整提示信息。
可选地，本实施例采用人脸识别的方式识别是否只采集到部分人脸，或者采用人体识别的方式识别是否只采集到部分身体，进而确定所述目标对象不完整。
可选地，在折叠屏实施例中，在所述预设位置的目标对象不完整时，可以通过提示用户旋转折叠屏的折叠角度的方式，调整所述摄像头所采集的范围，进而重新执行上述各个实施例以在所述预览界面上重新生成目标图像数据。需要说明的是，所述折叠屏的折叠角度调整后，可以调整位于两个屏幕上的摄像头采集的图像范围，使得重叠区域减小，增加两个摄像头的采集视角，使得预设位置的目标对象能够被采集到完整的图像。可以理解的是，若所述摄像头为前置摄像头，则提示增大所述折叠角度，也即展开所述折叠屏。若所述摄像头为后置摄像头，则提示减小所述折叠角度，也即折叠所述折叠屏。
在非折叠屏实施例中，在所述预设位置的目标对象不完整时，可以通过提示用户调整移动终端位置，使得摄像头与目标对象的距离更有，增大摄像头的视场范围，从而使得预设位置的目标对象能够被采集到完整的图像。
第五实施例：
请参照图10，本申请还提供一种拍照方法，所述拍照方法包括：
步骤S210，控制至少两个所述摄像头采集图像数据；
步骤S220，识别所述摄像头采集的图像数据的目标对象；
步骤S230，在所述目标对象不一致时，根据所有所述摄像头采集的图像数据生成所述目标图像数据；
步骤S240，于所述移动终端的预览界面显示所述目标图像数据。
需要说明的是，所述目标对象不一致是指至少一个摄像头所采集的图像数据中的目标对象与其它摄像头采集的图像数据中的目标对象不一一对应，如第一摄像头采集的图像数据中具有A成员、B成员和C成员，而第二摄像头采集的图像数据中具有A成员和D成员。
各个所述摄像头采集的图像数据中的目标对象一一对应时，所述目标对象一致，如第一摄像头采集的图像数据中具有A成员、B成员和C成员，而第二摄像头采集的图像数据中也具有A成员、B成员和C成员。
可选地，本实施例通过人脸识别技术识别各个所述摄像头所采集的图像数据中的所述目标对象是否一致。
在所述目标对象一致时，可以基于图像数据的显示特征来确定目标图像数据，如将显示特征优于其它摄像头采集的图像数据的显示特征的图像数据作为所述目标图像数据，可选地，所述特征信息还可包括显示特征，所述显示特征包括目标对象的显示位置、目标对象的显示清晰度、目标对象的显示亮度和图像分辨率中的至少一种。
本实施例应用场景与上述第一实施例应用场景相同，不同的是，本实施例在控制至少两个所述摄像头采集图像数据后，直接识别各个所述摄像头所采集的图像数据中的目标对象，判断各个所述摄像头所采集的目标对象是否一致。目标对象不一致时，存在以下情况(以合照为例)：
1、目标对象数量相同，但是所有摄像头都采集到部分人员，且所采集到的人中存在不重复的人。如10人合照，一个摄像头的图像数据中包括5个人，而另一个摄像头的图像数据中包括5个人。
2、目标对象数量不同，但是所有摄像头都采集到部分人员。如10个人合照，一个摄像头的图像数据中包括6个人，而另一个摄像头的图像数据中包含8个人，可选地只有四个人是重复的。
基于此，在所述目标对象不一致时，根据所有所述摄像头采集的图像数据生成所述目标图像数据，使得所述目标图像数据于预览界面显示时，呈现目标对象更多的画面，基于所述预览界面的预览数据生成目标图像时，能够获得拍照效果更佳的图像，如合照时，更容易获得合照人员更全的拍摄位置，无需用户来回移动调整终端的位置。
第六实施例：
本实施例基于上述第五实施例，可选地，所述根据所有所述摄像头采集的图像数据生成所述目标图像数据的步骤包括：
获取其它摄像头采集的图像数据中与目标摄像头采集的图像数据不重叠的非重叠区；
将所述非重合区域对齐到所述目标摄像头采集的图像数据的拼接位置；
调整所述拼接位置的图像特征，使得所述拼接位置的相似度大于或等于预设阈值；
基于调整后的图像数据生成目标图像数据。
在确定各个摄像头所采集的目标对象不一致时，则说明所有摄像头均只采集到部分目标对象，此时，将各个所述摄像头采集到的图像进行拼接，以形成更完整的目标图像数据。
可选地，在各个所述摄像头采集的图像数据中不具有重合区域时，则直接将各个图像数 据进行拼接，以获得目标图像数据。
可选地，若各个所述摄像头采集到的图像数据部分相同时，则说明各个图像数据具有重叠区和非重叠区。预先确定目标摄像头所采集的图像数据，然后扫描其它摄像头采集的图像数据，获取到与所述目标摄像头采集的图像数据不重叠的非重叠区域，然后将所述非重叠区域对齐到所述目标摄像头采集的图像数据的拼接位置。可选地，所述图像数据的非重叠区域与所述重叠区域之间的分界位置为所述拼接位置。
可选地，可以采用抠图的方式对所述其它摄像头的非重叠区域进行处理。
为了使得拼接后的图像融合和自然，在拼接图像过程中，将所述非重叠区域的图像数据对齐到所述目标摄像头采集的图像数据的对应位置后，调整所述拼接位置的图像纹理和/或色彩，使得所述拼接位置的相似度接近相似。
可选地，所述图像特征包括纹理和/或色彩中的至少一个，所述相似度基于纹理差异和/或色彩差异中的至少一个确定。所述纹理差异越小和/或所述色彩差异越小，所述拼接位置的相似度越大。
在一实施例中，所述相似度是基于所述拼接位置划分的至少一个点对应的色彩或纹理的差异值确定的，在所述拼接位置中具有达到预设数量的点对应的色彩或纹理的差异值小于预设差值，则判定所述拼接位置的相似度大于或等于所述预设阈值。
在一些实施例中，所述相似度是基于所述拼接位置划分的至少一个点对应的色彩和/或纹理的差异值的和确定的。如获取一摄像头对应的点的色彩和/或纹理与另一摄像头对应的点和纹理的差异值，把纹理差异和/或色彩差异这两个差异相加作为对比数值，如一摄像头的第i点和另一摄像头的第i点的纹理和/或图像色彩的绝对值差异值C＝|Ti1-Ti2|+|Ci1-Ci2|越小，相似度越相似。
具体调节过程中，根据色彩差异或纹理差异进行调整，如以目标图像数据中的色彩作为基准，调整所述其它数据中的非重叠区域的色彩，使得所述目标图像数据的色彩和其它数据的非重叠区域的色彩的差值最小化；或者，以目标图像数据中的纹理作为基准，调整所述其它数据中的非重叠区域的纹理，使得所述目标图像数据的纹理和其它数据的非重叠区域的纹理的差值最小化，实现图像拼接。
可选地，所述基于调整后的图像数据生成目标图像数据的步骤包括：基于调整后的图像数据对所述拼接位置进行融合处理；基于处理后的图像数据生成所述目标图像数据。调整所述目标图像数据和所述非重合区域的图像数据之间的拼接位置的图像特征后，融合所述拼接位置。如对所述拼接位置进行自然过渡融合处理，使得非重叠区域与所述目标图像数据融合，提高图像的显示效果。
可选地，本实施例中的目标摄像头可以为用户设定，如用户实现设定摄像头1为主摄像头，其它摄像头为辅助摄像头，则在采集到图像数据后，将其它摄像头采集到的图像数据拼接到主摄像头采集到的图像数据中。
或者，所述目标摄像头可以基于所采集的图像分辨率确定，如图像分辨率高的图像数据对应的摄像头为所述目标摄像头，图像分辨率低的为所述其它摄像头。
本实施例在图像拼接过程中，对拼接位置进行处理，使得拼接后的图像显示自然，提高图像的显示效果。
