【摘要】 人体动作的视觉分析是未来智能化康复训练、体育教学等系统亟待解决的课题。在人体骨骼特征点选取、特征点描述方法研究的基础上，以对人体动作正误提出高效识别方法并给出直观的矫正标识为目的，设计一种基于特征骨骼点间的相对二维向量的特征描述和余弦相似度相结合的动作比对方法。针对错误骨骼点，根据目标动作的特征描述计算出矫正后的正确位置。经自建数据集上的实验表明，本文模型对动作错误点检测灵敏，矫正效果直观、有效。更多还原

【Abstract】 The visual analysis of human action is an urgent problem to be solved in the future intelligent rehabilitation training,physical education and other systems. Based on the research of human bone feature point selection and feature point description method,in order to propose an efficient recognition method for human action correctness and give intuitive correction marks,an action comparison method based on the combination of feature description of relative two-dimensional vector between feature bone points and cosine similarity is designed. For the wrong bone points,the position after correction is calculated according to the feature description of the characteristic action. The experiment on the self built data set shows that the model is sensitive to the detection of action error points,and the correction effect is intuitive and effective.更多还原
