Description

一种镜面式健身信息交互方法及系统
本申请要求于2021年10月19日提交中国专利局、申请号为202111216065.6、名称为“一种镜面式健身信息交互方法及系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及健身信息数据处理,具体涉及一种镜面式健身信息交互方法及系统。
背景技术
健身是一种体育项目,如各种徒手健美操、韵律操、形体操以及各种自抗力动作,体操,瑜伽可以增强力量、柔韧性,增加耐力,提高协调,控制身体各部分的能力,从而使身体强健。
目前,存在多种多样的家用健身器材,其中可以直接显示健身教练视频的健身器材已经越来越广泛,然而这些健身器材难以让健身者准确的判断自身健身运动的准确性。
发明内容
本申请多个方面提供的镜面式健身信息交互方法及系统,能够让健身者准确的判断自身健身运动的准确性。
一方面,公开了一种镜面式健身信息交互方法,包括:
获取健身视频流作为第一图像数据,并获取用户在镜面处反射的图像作为第二图像数据;
根据第二图像数据对第一图像数据进行修正至满足预设条件;预设条件是修正后的第一图像数据中教练的形体尺寸对应于第二图像数据中用户的形 体尺寸;
将修正后的第一图像数据显示于镜面处,并重叠于镜面上的反射图像;修正后的第一图像数据中教练的动作与反射图像中用户的动作相同时,修正后的第一图像数据中教练的形体与反射图像中用户的形体重合。
一些相关技术中,对于健身者自身健身运动的准确性主要采用通过穿戴传感器或者视频检测的方式对健身者的动作情况进行打分,但是打分结果往往只能显示健身者的动作是否达标,而不能让健身者直观的了解哪个部位的动作没有达标。
本实施例实施时,通过用户的选择请求或者定时播放等方式请求健身视频流,并将接收到的健身视频流作为第一图像数据,应当理解的是,健身视频流的获取方式可以是基于互联网的数据传输、短距数据传输、预存储等任何一种现有的方式,本实施例在此不多做限定。
第一图像数据中视频的录制方式与用户在镜面前所获取的反射图像往往会差异比较大,示例的,当第一图像数据录制时,教练的形体可能相比用户的差异较大,在进行健身时,如果直接显示第一图像数据,无论用户如何在镜面前调整自己的位置都是很难进行动作姿态的比对的。所以在本实施例中还获取了用户在镜面处反射的图像作为第二图像数据,以对第一图像数据进行修正。
本实施例中,需要通过可以进行计算的设备将根据第二图像数据对第一图像数据进行修正,修正的结果需要满足第一图像数据中教练的形体尺寸与第二图像数据中用户的形体尺寸基本相符,应当理解的是,修正方式可以采用局部的尺寸修正和整体的尺寸修正,当修正后的第一图像数据展示于镜面下方时,修正后的第一图像数据中教练的形体可以与反射图像中用户的形体重合,应当理解的是,此处说的重合可以是完全重合,也可以是大致重合,只需要以用户的视角看起来时在做相同动作时可以展现出差异即可。本申请通过上述技术,实现了健身者在健身过程中对自己健身动作与标准动作 差异的实时监控,有效提高了健身效率,也提升了健身者的使用感受。

在下面的描述中阐述了很多具体细节以便于充分理解本申请,但是,本申请还可以采用其他不同于在此描述范围内的其他方式来实施,因此,本 申请的保护范围并不受下面公开的具体实施例的限制。
本领域技术人员应理解的是,在本申请的揭露中,术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系是基于附图所示的方位或位置关系,其仅是为了便于描述本申请和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此上述术语不能理解为对本申请的限制。
可以理解的是,术语“一”应理解为“至少一”或“一个或多个”,即在一个实施例中,一个元件的数量可以为一个,而在另外的实施例中,该元件的数量可以为多个,术语“一”不能理解为对数量的限制。
请结合参阅图1,为本申请实施例提供的一种镜面式健身信息交互方法的流程示意图,该镜面式健身信息交互方法可以应用于图2中的镜面式健身信息交互系统。镜面式健身信息交互方法具体可以包括以下步骤S1-步骤S3所描述的内容。
S1:获取健身视频流作为第一图像数据,并获取用户在镜面处反射的图像作为第二图像数据。
S2:根据第二图像数据对第一图像数据进行修正至满足预设条件;预设条件是修正后的第一图像数据中教练的形体尺寸对应于第二图像数据中用户的形体尺寸。
S3:将修正后的第一图像数据显示于镜面处,并重叠于镜面上的反射图像;修正后的第一图像数据中教练的动作与反射图像中用户的动作相同时,修正后的第一图像数据中教练的形体与反射图像中用户的形体重合。
本实施例实施时,通过用户的选择请求或者定时播放等方式请求健身视频流,并将接收到的健身视频流作为第一图像数据,应当理解的是,健身视频流的获取方式可以是基于互联网的数据传输、短距数据传输、预存储等任何一种现有的方式,本实施例在此不多做限定。
第一图像数据中视频的录制方式与用户在镜面前所获取的反射图像往往会差异比较大,示例的,当第一图像数据录制时,教练的形体可能相比用户的差异较大,在进行健身时,如果直接显示第一图像数据,无论用户如何在镜面前调整自己的位置都是很难进行动作姿态的比对的。所以在本实施例中还获取了用户在镜面处反射的图像作为第二图像数据,以对第一图像数据进行修正。
本实施例中,需要通过可以进行计算的设备将根据第二图像数据对第一图像数据进行修正,修正的结果需要满足第一图像数据中教练的形体尺寸与第二图像数据中用户的形体尺寸基本相符,应当理解的是,修正方式可以采用局部的尺寸修正和整体的尺寸修正,当修正后的第一图像数据展示于镜面下方时,修正后的第一图像数据中教练的形体可以与反射图像中用户的形体重合,应当理解的是,此处说的重合可以是完全重合,也可以是大致重合,只需要以用户的视角看起来时在做相同动作时可以展现出差异即可。本申请通过上述技术,实现了健身者在健身过程中对自己健身动作与标准动作差异的实时监控,有效提高了健身效率,也提升了健身者的使用感受。
示例的,请参阅图3,图3中示出了现有技术经常存在的困难,用户102在镜面101面前时,镜面101反射出的用户形体的反射图像103,而在获取了第一图像数据104并直接展示时,反射图像103和第一图像数据104存在明显的比例差异,或者存在位置差异。
示例的,请参阅图4,图4中示出了本实施例的具体方案效果,同样的,用户102在镜面101面前时,镜面101反射出的用户形体的反射图像103,而在获取了第一图像数据并进行修正,修正后的第一图像数据105与反射图像103在一定的预设姿势下出现了大致的重合,这样当用户102在镜面101前做出与修正后的第一图像数据105相对应的动作时,是可以从镜面101的反射图像103中直观的看出与修正后的第一图像数据105的差异。
在一些实施例中,步骤S2包括以下子步骤:
S21:从第一图像数据中提取特征点的坐标数据形成第一坐标数据,并从第二图像数据中提取对应的特征点的坐标数据形成第二坐标数据。
S22:根据第二坐标数据与第一坐标数据的差异修正第一图像数据中的每一帧至满足预设条件。
本实施例实施时,作为一种更具体的实现方式,采用了通过提取特征点来进行第一图像数据修正的方式,应当理解的是,在步骤S1中,第一图像数据中提取的特征点和第二图像数据中提取的特征点应当是对应的,其对应关系可以是位于大致相同的部位的大致相同的点位。同样的,对于第一图像数据的修正应当是对每一帧进行修正,具体修正过程可以同时对每一帧进行修正,也可以在播放修正后的第一图像数据时,对后续的帧进行持续修正,无论采用何种方式进行修正,都应当被认为是在本实施例的范围内。
在一些实施例中,从第一图像数据中提取特征点的坐标数据形成第一坐标数据,并从第二图像数据中提取对应的特征点的坐标数据形成第二坐标数据包括:
从第一图像数据中选取教练达到预设姿势的帧作为第一关键帧,并提取第一关键帧中教练预设部位的轮廓;从第二图像数据中选取用户达到相同预设姿势的帧作为第二关键帧,并提取第二关键帧中用户相同预设部位的轮廓;基于第一关键帧对应的轮廓提取特征点并生成第一坐标数据,基于第二关键帧对应的轮廓提取特征点并生成第二坐标数据。
本实施例实施时,为了提取相同或相似特征点,需要将第一图像数据和第二图像数据提取特征点的姿势、部位保持一致,在本实施例中的预设姿势可以采用固定站姿、固定坐姿、固定躺姿等便于用户保持的姿态,而对于预设部位可以采用上臂、大腿、肩膀等易于识别的部位,也可以使用多个部位同时作为预设部位。示例的,采用上臂和大腿同时作为预设部位,通过对上臂和大腿上特征点的位置关系,将第一图像数据进行修正。应当理解的是从轮廓中提取特征点的方式,可以采用现有技术中的任何提取方式,由于 轮廓线往往也是经过特征点进行生成的,所以采用这些生成轮廓线的特征点作为本实施例中的特征点,也可以是在生成了轮廓线后在轮廓线上提取更符合需求的点作为特征点,本实施例在此不多做限定。
在一些实施例中,基于轮廓提取特征点包括:
提取轮廓中至少三个点作为特征点,特征点均为轮廓中的拐点;基于第一关键帧提取的特征点对应于基于第二关键帧提取的特征点。
本实施例实施时,第一关键帧所提取的特征点应当在部位和位置上与第二关键帧的位置大致相同,其具体部位和位置的选择可以通过预设的方式进行约定,而提取至少三个特征点可以保证检测结果的准确度,为了进行第一图像数据的修正,需要从多个方向上进行修正,获取的特征点越多,可以修正的方向就越多;同样的一般轮廓线中最显著的特征会在轮廓线上被表征为拐点,所以在本实施例中采用了轮廓中的拐点作为特征点。
在一些实施例中,根据第二坐标数据与第一坐标数据的差异修正第一图像数据中的每一帧至满足预设条件包括:
基于第二坐标数据形成用户形体尺寸数据,并基于第一坐标数据形成教练形体尺寸数据;根据用户形体尺寸数据与教练形体尺寸数据在至少一个方向上的比例对第一图像数据中的每一帧在方向上进行裁剪和/或缩放。
本实施例实施时,为了可以实现快速对第一图像数据的修正,在本实施例中采用通过坐标数据形成尺寸数据,形成方式可以是采用特征点之间的欧拉距离等方式。示例的,将第二坐标数据对应的两个特征点连线,并将第一坐标数据对应的两个特征点连线,根据连线的长度的比值沿连线方向对第一图像数据进行拉伸或者压缩。
示例的,当根据连线的长度的比值沿连线方向对第一图像数据进行拉伸或者压缩后,可以选取与当前拉伸或者压缩方向正交的方向进行特征点之间的连线,并在此根据连线的长度的比值沿连线方向对第一图像数据进行拉伸或者压缩。
