Real time recognition method ofTai Chi boxing video error action considering feature and rate

Tai Chi has become a daily exercise for people. Taijiquan is a summary of the practitioners' long-term practice and experience of body changes. After historical inheritance, many theories have been neglected, and more and more people pay attention to the scientific study of Taijiquan. In this paper, the characteristic values of motion signal are extracted from time domain and rate. The representative characteristics of motion are studied. The dimension reduction of the extracted eigenvalues is used to improve the subsequent efficiency. Draw the characteristic curve, and extract the characteristic law of the movement electrical signal of Tai chi long-term practitioners through the comparative analysis of the practitioners. In the experiment, the differences between long-term and short-term exercisers' motor signal characteristic values are used to achieve the graphical display of characteristic signals through the design of a small training system to make the internal movement training explicit and intuitive, and provide guidance for the further training of Tai Chi boxing.
