具体实施方式
下面结合附图阐述本发明的摄像控制方法、系统及交互智能平板一体机的实施例。
参考图1所示,图1是本发明实施例的摄像控制方法流程图,用于交互智能平板的摄像控制,主要包括如下步骤:
S100,在移动摄像头启动后,控制移动摄像头在交互智能平板的拍摄范围内进行扫描拍摄,得到预览图像;从预览图像中识别操作者图像,并将操作者图像出现在图像的预设边缘线内时移动摄像头的拍摄角度设为初始角度;其中,所述移动摄像头为设置在交互智能平板上,在水平和垂直方向上受控的摄像头。
上述步骤S100,是在进入步骤S101的拍摄过程前的一种实施例的操作方式,在移动摄像头启动后,通过扫描方式搜索到交互智能平板前的操作者,作为初始拍摄角度,然后控制移动摄像头跟随操作者位置移动。
S101,在操作者操作交互智能平板时,控制移动摄像头拍摄交互智能平板前方区域的图像,获取原始图像;其中,所述移动摄像头为设置在交互智能平板上,在水平和垂直方向上受控的摄像头。
操作者操作交互智能平板时,会在交互智能平板前来回走动,控制移动摄像头拍摄交互智能平板前方区域一定范围内的图像,作为原始图像。
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。
一般情况下,人体形状是有基本固定的轮廓,通过人体轮廓图像与拍摄图像的帧图片进行匹配运算,可以识别拍摄图像中的人体图像。
对于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的方法,可以包括如下过程:
根据所述位置信息确定所述操作者图像的最小外接矩形;当最小外接矩形的左右两侧的边线超出图像两侧的边缘线时,计算所述边线与对应一侧边缘线的第一距离;根据所述第一距离计算水平角度调整量。
进一步的,当最小外接矩形的上部边线超出图像上下部的边缘线时,计算所述边线与对应边缘线的第二距离;根据所述第二距离计算高度调整量。
参考图2所示,图2是操作者图像变化示意图,正常情况下,如上图(a),图中人体图像(即操作者图像)在边缘线(虚线)的范围内。如中图(b),若人体图像超出左侧的边缘线,为了将人体图像拉回边缘线范围内,可以计算最小外接矩形的边线超出距离d,这样就可以计算出角度调整量。同理,在上部边缘线,如下图(c)所示,为了将人体图像拉回上部边缘线范围内,可以计算最小外接矩形上部的边线超出距离d,这样就可以计算出高度调整量。
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。
