Abstract

一种人体运动的捕获方法，它涉及人体运动信息检测技术领域，它采用以下捕获方法：(1)、将感应器固定在一个松紧套圈上，松紧套圈的大小与待测部位的大小相吻合；(2)、将套圈套接在待测部位的关节点；(3)、利用传感器的穿到作用，使用摄像机拍摄；(4)、使用拍摄误差较小的数幅图形进行测量3D坐标，取数幅图像测量出来的坐标值的平均值，然后对首帧图像中人体棍状模型初始化；(5)、测出的3D位置投影到双目摄像头所对应的图像上，结合预测出的关节点的位置信息和实际过程中提取的关节点的位置信息进行关节点的跟踪，从而获取各个关节点在视频中的运动轨迹。它根据平均或值获得数据，数据准确，且产品方便佩戴，实用性较强。

Description

一种人体运动的捕获方法
 
技术领域：
本发明涉及人体运动信息检测技术领域，具体涉及一种人体运动的捕获方法。
背景技术：
运动人体科学是研究体育运动与人的机体的相互关系及其规律的学科群。包括运动解剖学、运动生理学、运动生物力学、运动生物化学、保健康复及运动医学等学科。
现在，通过感知和获取准确的人体姿态和位置运动信息，能够根据运动员各肢体的运动轨迹分析存在的问题并改进训练，能够根据人体步态的变化推断可能存在的疾病，能够根据人体运动信息的跟踪建立高水平的3D 游戏，能够根据人体运动姿态的跟踪为数字电影、虚拟世界构建栩栩如生的角色。
目前，公知的运动捕获的方法主要包括基于机械、电磁、声学、光学和图像的设备的运动获取方法，这些方法有两个很大的缺点：需要的运动捕获设备体积较大，佩戴不方便，放置在人体的感应器只有一个，数据计算不准确，并且附加在人体身上的传感器限制了演员的自由表演。
发明内容：
本发明的目的是提供一种人体运动的捕获方法，它根据平均或值获得数据，数据准确，且产品方便佩戴，实用性较强。
为了解决背景技术所存在的问题，本发明是采用以下技术方案：它采用以下捕获方法：1、将感应器固定在一个松紧套圈上，松紧套圈的大小与待测部位的大小相吻合；2、将套圈套接在待测部位的关节点；3、利用传感器的穿到作用，使用摄像机拍摄；4、使用拍摄误差较小的数幅图形进行测量3D坐标，取数幅图像测量出来的坐标值的平均值，然后对首帧图像中人体棍状模型初始化；5、测出的3D 位置投影到双目摄像头所对应的图像上，结合预测出的关节点的位置信息和实际过程中提取的关节点的位置信息进行关节点的跟踪，从而获取各个关节点在视频中的运动轨迹。
本发明具有以下有益效果：它根据平均或值获得数据，数据准确，且产品方便佩戴，实用性较强。
具体实施方式：
本具体实施方式采用以下技术方案：它采用以下捕获方法：1、将感应器固定在一个松紧套圈上，松紧套圈的大小与待测部位的大小相吻合；2、将套圈套接在待测部位的关节点；3、利用传感器的穿到作用，使用摄像机拍摄；4、使用拍摄误差较小的数幅图形进行测量3D坐标，取数幅图像测量出来的坐标值的平均值，然后对首帧图像中人体棍状模型初始化；5、测出的3D 位置投影到双目摄像头所对应的图像上，结合预测出的关节点的位置信息和实际过程中提取的关节点的位置信息进行关节点的跟踪，从而获取各个关节点在视频中的运动轨迹。
本具体实施方式根据平均或值获得数据，数据准确，且产品方便佩戴，实用性较强。
