Description

头部感应井下摄像头控制方法
技术领域
本发明涉及一种体感控制***和方法,具体是一种头部感应井下摄像头控制方法,属体感控制技术领域。
背景技术
在煤矿调度中心,通过液晶显示屏可以很轻松看到井下的工作状态,如采煤机的工作姿态,皮带运输机工作是否正常等,当我们想旋转井下摄像头看到更多场景时需要控制鼠标来实现,无形之中给人们带来了极大的不便。
发明内容
针对上述存在的问题,本发明提供一种头部感应井下摄像头控制方法。
本发明是通过如下技术方案实现的:首先获得人体骨骼三维信息,对得到的人体骨骼三维信息进行分析运算编码,封装成一系列头部姿态,使得计算机能对人做出的各种姿势进行识别,从而实现井下摄像头按照头部姿势进行动作;具体步骤如下:
步骤一、采集人体节点,建立人体节点坐标系;
步骤二、将每个节点初始坐标数据存入数组;
步骤三、采集当前的各个节点坐标,并将其存入数组;
步骤四、根据当前各个节点的坐标计算头部摆动角度,井下摄像头依此决定向左旋转还是向右旋转。
步骤四中所述井下摄像头向左旋转还是向右旋转的控制方法为:
1)获取面部鼻头节点的初始坐标(x0,y0,z0);
2)获取面部鼻头节点的当前坐标(x1,y1,z1);
3)获取脊柱节点的初始坐标(x2,y2,z2);
4)计算头部旋转角度θ是否处于15°~20°和-20°~-15°;
若θ处于15°~20°则井下摄像头向左旋转,返回;若θ处于-20°~-15°则井下摄像头向右旋转,返回;否则井下摄像头不运动;
cos θ = ( ( x 0 - x 2 ) 2 + ( y 0 - y 2 ) 2 + ( x 1 - x 2 ) 2 + ( y 1 - y 2 ) 2 - ( x 0 - x 1 ) 2 + ( y 0 - y 1 ) 2 ) 2 ( x 0 - x 2 ) 2 + ( y 0 - y 2 ) 2 ( y 1 - y 2 ) 2 - ( x 0 - x 1 ) 2 y 1 - y 2 | y 1 - y 2 |
当cosθ>0时,θ=arccosθ;当cosθ<0时,θ=π-arccosθ。
本方法的优点是,可以不使用鼠标方便的旋转井下摄像头看到更多场景。
附图说明
图1是本发明所述的头部感应识别方法的流程图。
图2为本发明所述的井下摄像头旋转信号和方向识别的流程图。
具体实施方式
下面结合附图对本发明的最佳实施方案作进一步的详细的描述
如图1所示,头部感应井下摄像头控制方法,步骤是:
步骤一、采集人体头部5个节点,颈部以下5个节点,建立人体关节点坐标系,定义每个节点的初始坐标;
步骤二、将每个节点原始坐标数据存入数组;
步骤三、采集当前的各个节点坐标数据,并将各个节点的坐标存入数组;
步骤四、计算头部摆动方向和角度,井下摄像头以此决定是向左旋转还是向右旋转。
如图2所示,井下摄像头向左旋转还是向右旋转的步骤为:
1)获取面部鼻头节点的初始坐标(x0,y0,z0);
2)获取面部鼻头节点的当前坐标(x1,y1,z1);
3)获取脊柱节点的初始坐标(x2,y2,z2);
4)计算头部旋转角度θ是否处于15°~20°和-20°~-15°;
若θ处于15°~20°则井下摄像头向左旋转,返回;若θ处于-20°~-15°则井下摄像头向右旋转,返回;否则井下摄像头不运动;
cos θ = ( ( x 0 - x 2 ) 2 + ( y 0 - y 2 ) 2 + ( x 1 - x 2 ) 2 + ( y 1 - y 2 ) 2 - ( x 0 - x 1 ) 2 + ( y 0 - y 1 ) 2 ) 2 ( x 0 - x 2 ) 2 + ( y 0 - y 2 ) 2 ( y 1 - y 2 ) 2 - ( x 0 - x 1 ) 2 y 1 - y 2 | y 1 - y 2 |
当cosθ>0时,θ=arccosθ;当cosθ<0时,θ=π-arccosθ。
本具体实施方式只是本发明的优选实施例,并不能对本发明进行限定,具体各项权利保护范围由权利要求书限定。
