随着科学技术的发展和社会经济水平的提高,混合现实设备出现并且以亲民的价格走入了千家万户的生活,各种具备身体数据监测功能的数字手表也成为人们生活中必备的消费品。基于混合现实设备和外置的人体生命体征传感器,通过蓝牙或者无线网络实现数据互联,并构建太极拳训练评估系统,可以有效地解决传统太极拳运动训练过程中缺乏专业指导,缺乏体征监测,缺乏效果评估的痛点,为健康人强身健体和患者重拾健康提供有意义的强化和指导。
再次,随着芯片技术的发展,各种生命体征的检测设备逐渐小型化和便携化,具备心肺检测功能的可穿戴式设备已经成为广大群众日常消费品。
最后,网络以及蓝牙等通讯方法的普及,使得各种不同类型的设备可以通过无线网络和蓝牙等方式进行数据传输和互联。
对此,本申请实施例提供了一种基于混合现实技术的太极拳训练系统,具体请参阅图1和图2,图1是本申请提供的太极拳训练系统的结构示意图,图2是本申请提供的太极拳训练系统的流程示意图。
如图1所示,本申请实施例的太极拳训练系统100包括混合现实设备11、若干体感摄像头12、处理终端13以及生命信号采集设备14。上述设备组成的太极拳训练系统100可以用于实现本申请提供的太极拳训练方法。
具体地,结合图2对图1的太极拳训练系统100进行介绍。体感摄像头12可以为图2所示的运动捕捉设备,处理终端13可以为图2所示的计算主机。其中,太极拳训练系统100包括硬件系统和软件系统两大部分。

需要说明的是,本申请实施例所涉及的运动包括多个领域以及多个方向的运动,例如,舞蹈运动、健身运动、生命运动等。在本申请对于以下实施例的介绍中,以太极拳运动为一种具体实施例进行介绍,因此,在后续描述中对于可以适用的运动类型不一一列举。
下面继续介绍适用于上述太极拳训练系统的太极拳训练方法,具体请参阅图3,图3是本申请提供的太极拳训练方法一实施例的流程示意图。
具体而言,如图3所示,本申请实施例的太极拳训练方法具体包括以下步骤:
步骤S31:获取预设全息太极拳动画。
在本申请实施例中,用户需要先搭建上述太极拳训练系统,包括搭建硬件系统和软件系统。
具体地,需要分别在用户的训练区域每间隔120°放置一台体感摄像机或者其他运动捕捉设备,每台摄像机或其他捕捉设备均正对着训练区域中的用户。需要说明的是,太极拳训练系统中的体感摄像机需要至少三台,且每台摄像设备与相邻摄像设备的距离和间隔角度相同。例如,当体感摄像机的数量为三台 时,则间隔角度应当设置为120°;当体感摄像机的数量为四台时,则间隔角度应当设置为90°。后面的描述中,以三台体感摄像机为例进行说明。
然后,将三台体感摄像机连接在同一台计算主机上。用户佩戴可穿戴式生命信号采集设备,并戴上混合现实眼镜或头盔。计算主机、混合现实设备和生命信号采集设备均通过无线信号进行连接,例如无线网络或者蓝牙等。
太极拳训练系统获取预先存储的全息太极拳动画,例如全息太极拳宗师全息影像。该全息太极拳动画需要在用户使用该太极拳训练系统提前录制制作,制作过程具体如下:
邀请太极拳师傅站在三台体感摄像机对准的中心处,启动系统进行全息影像的录制。三台体感摄像机从不同的方位和角度识别太极拳师傅的动作并提取骨架,由于三台体感摄像机的识别结果可以交叉验证,因此可以大大提供太极拳所有招式的识别率,包括含有转身的招式。提取到太极拳师傅的之后,我们将太极拳的不同招式的骨架运动信息保存作为标准的招式指导数据库。然后通过三维建模和骨骼动画绑定,建立虚拟的太极拳师傅形象,并将招式骨架运动信息绑定在虚拟的太极拳师傅模型上,这样就达到了施展全套太极拳的虚拟太极拳师傅动画。
其中,对于识别结果的交叉验证,可以采用三台体感摄像机提取的骨架信息中的骨架位置均值得到最终确定的骨架信息,也可以将某一台体感摄像机提取的骨架位置作为初始值,例如其他两台体感摄像机提取的骨架位置对该初始值进行验证和调整等。
下面,即可根据提前录制的全息太极拳动画对用户进行实时的太极拳指导训练。
步骤S32:播放预设全息太极拳动画,以及采集用户的太极拳训练动画。
在本申请实施例中,太极拳训练系统启动之后,混合现实眼镜或混合现实头盔内部渲染虚拟的三维太极拳师施展太极拳的动画,形成虚拟的太极拳师全息投影。
进一步地,由于在运动过程中,用户的位置和朝向都在不同变化,因此需 要结合用户的实时位置和实时朝向对虚拟的太极拳师傅全息投影进行位置上的调整。
具体地,太极拳训练系统根据混合显示头盔上的陀螺仪和/或惯性传感器检测用户头部的位置以及朝向,然后将三维太极拳师的全息影像渲染到用户头部的朝向,使用户无论在施展太极拳的何种招式,例如包括转身的招式时,均可以在眼前看到全息太极拳师的投影作为动作指导,如图4所示,保持太极拳师傅的全息投影在用户的可视范围内。
太极拳训练系统除了可以展示太极拳师傅的全息投影外,还可以利用系统中的体感摄像头实时采集用户的太极拳训练动画。一方面可以将用户的太极拳训练动画和预设全息太极拳动画进行融合显示,使得用户可以实时查看自身太极拳动作和标准太极拳动作之间的差距,以及实时的动作比对指导,如图5所示,可以将太极拳训练动画与预设全息太极拳动画进行叠加显示,使得动作比对效果更明显;另一方面可以通过将太极拳训练动画与预设全息太极拳动画进行匹配,以获取用户的太极拳标准程度。
步骤S33:将预设全息太极拳动画以及太极拳训练动画进行匹配,获取并输出用户的太极拳标准程度。
在本申请实施例中,太极拳训练系统通过将预设全息太极拳动画以及太极拳训练动画进行匹配,实现实时的太极拳动作标准度评估。
由于太极拳训练系统预先存储全息太极拳动画,可以直接提取标准的太极拳的标准骨架运动信息。在用户进行实时的太极拳训练时,三台体感摄像机提取用户的训练骨架运动信息,并将标准的太极拳师的动作与用户的运动骨架进行映射。
具体地,太极拳训练系统可以将标准太极拳师傅施展太极拳时的全息影像进行移动,并根据体感数据检测到用户骨架数据进行身高上的缩放,使虚拟的太极拳师与用户的真实位置进行匹配和重叠渲染。这样,当用户施展太极拳时,不仅可以如步骤S32那样在视角的身体朝向的正前方看到标准太极拳师的全息投影指导,还可以看自己身上标准太极拳师打拳的投影,观察自己的肢体与全息太极拳师肢体的偏移角度,从主观上对自己的动作准确度进行评估,并通过 移动自己的肢体与全息太极拳师的对应肢体重合的方式对自己的动作进行自主纠正。
除此之外,太极拳训练系统根据用户骨架上不同关节节点(肩关节、膝关节、腕关节等)与标准太极拳师傅对应关节的位置偏移量,定量分析用户的太极拳标准程度,为用户的训练提供数据指导。
进一步地,太极拳训练系统还可以对用户的生命体征进行实时监测。
由于用户身上佩戴着可穿戴式的生命体征监测设备,以心跳监测传感器为例。心跳传感器可以实时监测用户的脉搏,并将数据通过无线信号传输手段传递到混合现实设备当中,将用户的实时心率显示在混合现实设备的可视区域,系统监测心跳数值,当超过正常范围时给出警示。
另外,当每次用户运动训练完成后,太极拳训练系统还可以实现用户训练数据的保存与重放以及太极拳评估和训练报告生成。
具体地,用户在整个训练过程中产生的太极拳运动骨架数据,以及各项生命体征数据均会进行记录并保存在混合现实设备中,并通过无线信号传输方式同步在电脑上。用户可以随时在混合显示设备中观看训练记录,该训练记录以时间顺序进行播放,用户可以看到自己施展太极拳的全息投影并查看实时的生命体征数据。
太极拳训练系统自动导出文本格式的太极拳评估和训练报告,从太极拳动作的准确度以及各种生理参数指标对用户的太极拳训练结果进行评价。
本申请实施例的太极拳训练系统可以为用户提供全时,全过程的太极拳大师全息投影指导,用户无论进行太极拳的何种动作,太极拳大师施展太极拳的全息投影都会在用户的可视范围内,避免传统训练方式下在施展某些转身动作时丢失指导;可以将标准太极拳动作的全息投影匹配到用户身上,用户在训练时观察自己的肢体位置与全息投影的肢体位置的偏差即可在主观上对自己的动作准确度有所评价,并可以通过将肢体移动与全息投影的标准重合的方式来纠正自己的动作;可以实时显示用户的心率等生命体征,并对异常数据进行检测给出训练警示和建议;采用混合现实设备,用户既可以看到全息投影的虚拟 物体,也可以看到真实世界,相对于完全沉浸式的虚拟现实头盔,本申请的太极拳训练方法安全性较高,也可以有效降低用户的晕眩感。
在本申请实施例中,太极拳训练系统获取预设全息太极拳动画;播放预设全息太极拳动画,以及采集用户的太极拳训练动画;将预设全息太极拳动画以及太极拳训练动画进行匹配,获取并输出所述用户的太极拳标准程度。通过上述方式,本申请的太极拳训练方法通过预设全息太极拳动画与用户实时的太极拳训练动画进行匹配的方式,对用户的运动进行实时的动作指导,对用户的运动训练提供很好的辅助作用和指导意义。
