具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”等所区分的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”,一般表示前后关联对象是一种“或”的关系。
现有的很多极限运动视频以及趣味视频都是专业运动人员配合专业摄像人员进行拍摄得到的。专业人士做这些动作都很危险,普通用户无法完成这些动作且大多数用户也不具备这些拍摄技巧。后期制作的技术门槛高, 请专业人士制作时间和金钱成本都比较高,所以普通用户像拍摄这样的趣味视频(如倒立空中行走,空中翻转等)是很困难的,而这类视频往往又很吸引人;目前用户获取趣味图像的难度较高。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的图像拍摄方法进行详细地说明。
图1示出了本申请一个实施例提供的图像拍摄方法的流程示意图。如图1所示,该方法可以包括以下步骤:
S110,在拍摄预览界面显示包含目标对象的第一图像的情况下,接收用户对第一图像的第一输入。
其中,第一输入用于确定第一图像的地平线方向,地平线方向用于确定目标对象的图像在合成第一目标图像时的旋转角度,该地平线方向由用户对第一图像的第一输入确定。
在一种实施例中,目标对象的图像和第一背景图像均包括备选方向标识;备选方向标识用于表征目标对象的图像和第一背景图像中的特征边缘走向;S110:接收用户对第一图像的第一输入,可以包括:

S120,响应于第一输入,将第一背景图像和第一主体旋转图像合成,得到第一目标图像。
其中,第一背景图像为第一图像中除目标对象的图像之外的图像,第一主体旋转图像为将目标对象的图像旋转第一转动角度后得到的图像,第一转动角度为第一重力方向相对地平线方向的角度;可以通过预先对目标对象的图像处理,进而得到第一背景图像和第一主体旋转图像。第一重力方向可以通过电子设备设置的重力传感器采集得到,基于第一重力方向和地平线方向即可计算得到第一转动角度。在合成第一目标图像时,目标对象的图像旋转后,目标对象的图像的一部分会覆盖到第一背景图像上,目标对象的图像原位置会出现部分空白,可通过图像修补算法以第一背景图像为参考对空白进行修补,图像修补算法可以选用为inpaint算法,最终得到第一目标图像,第一目标图像可以如图4所示。

S130,显示第一目标图像。
其中,在得到第一目标图像后,可以显示第一目标图像,用户可以直观观察第一目标图像的拍摄效果,优化用户体验。基于本申请实施例,可以连续拍摄目标对象的第一目标图像,并按时序展示第一目标图像,形成视频,该视频各帧中背景图像不进行旋转,而主体图像按统一的角度旋转,形成趣味十足的视频效果。
