S102,根据图像数据识别操作者图像,计算所述操作者图像在原始图像中的位置信息,根据所述位置信息计算操作者图像移动至图像的预设边缘线内所需的角度调整量;
此步骤中,通过图像识别技术识别出操作者,为了将操作者始终控制在
图像中的一个区域内,可以计算图像中操作者图像的位置信息,即在图片中的位置信息,利用预设的边缘线,当操作者图像超过边缘线的时候,说明操作者将要离开移动摄像头的拍摄范围,此时通过操作者运动方向,计算出将操作者控制在边缘线范围内时,图像的拍摄角度所需的角度调整量。
作为一个实施例,所述从预览图像中识别操作者图像的方法,可以提取所述预览图像的帧图片,利用预存的人体轮廓图像与所述帧图片进行匹配运算,识别出预览图像中的操作者。

S103,根据所述角度调整量生成拍摄角度调整指令,将拍摄角度调整指令发送至移动摄像头调整拍摄角度。
对于角度调整,将角度调整量下发至移动摄像头,移动摄像头根据该调整量来控制拍摄角度。如果是需要调整高度,则根据所述高度调整量生成拍摄高度调整指令,将拍摄高度调整指令发送至移动摄像头调整拍摄高度。
上述实施例的方案,通过移动摄像头拍摄操作者图像,识别操作者图像
在原始图像的位置信息,从而进行预测计算角度调整量,控制移动摄像头调整角度,将操作者图像拉回到图像中的一定范围内;能够根据不同场景调整拍摄角度,确保操作者图像完整性,可以适应不同场景的拍摄需求,提升了用户体验。
