摘要

本文根据Kinect V2.0深度测量原理中的TOF方法,获取Kinect数据流,实现对用户瑜伽动作数据的实时采集。在提取关节运动特征的基础上,利用动作重定向算法依次计算模型中各关节点在模型坐标系下的位置。针对关节瑜伽动作画面中关键帧的间歇性问题,有必要通过动作关键帧插值方法对瑜伽动作识别进行优化分析。从运动瑜伽教学的需求出发,确定了计算机辅助瑜伽教学系统的设计方案,在系统开发平台和编程程序的基础上实现了计算机辅助瑜伽教学系统的设计,并通过仿真分析对计算机辅助瑜伽教学系统的性能进行了测试。结果表明,瑜伽动作重定向算法在匹配同一动作的数据信息时,距离值比不同瑜伽动作序列之间的匹配距离小1 ~ 2个数量级,并且利用关节角度值可以找出训练者动作不达标的关节;瑜伽教练可以根据系统给出的相似度和关节角度值合理调整动作,达到瑜伽训练的目的。

An analysis of the application of computer-assisted instruction in the teaching of physical education yoga
Abstract In this paper, according to the TOF method in the principle of Kinect V2.0 depth measurement, the Kinect data stream can be obtained, which can realize the real-time acquisition of the user’s yoga movement data. On the basis of the extraction of joint motion features, the position of each joint point in the model under the model coordinate system is calculated sequentially using the action redirection algorithm. For the intermittent problem of keyframes in the yoga action screen of the joints, it is necessary to optimize the analysis of yoga action recognition through the action keyframe interpolation method. Starting from the demand for sports yoga teaching, we determine the design scheme of a computer-aided yoga teaching system, realize the design of a computer-aided yoga teaching system based on the system development platform and programming program, and test the performance of the computer-aided yoga teaching system by using simulation analysis. The results show that the yoga movement redirection algorithm, when matching the data information of the same movement, the distance value is 1 to 2 orders of magnitude smaller compared to the matching distance between different yoga movement sequences, and the use of the joint angle value can find out the joints where the trainer’s movement is not up to the standard, and the yoga trainer can reasonably adjust the movement based on the similarity and the joint angle value given by the system to achieve the purpose of yoga training.
