A method for evaluating the quality of fitness movements without equipment based on micro-inertia

Abstract

The invention discloses a micro-inertia-based method for evaluating the quality of body-building exercises without equipment, which can identify and evaluate the quality of body-building exercises without equipment. The method adopts a state-action two-step classification method. Firstly, three 6-axis micro-inertial sensors are used to identify the human body motion state, and then the Elman-Kalman trajectory estimation model is called to predict the trajectory of each sensor node, and then the trajectory signal is combined with the collected signal. It is used for the second step of fitness action classification. After the classification is completed, compare and analyze the generated motion sequences with the sequences in the standard motion sequence library, evaluate the whole body and local standard and stability of the movement, and give the movement quality evaluation results to help people efficiently and safely Carry out freehand fitness activities. The invention can effectively identify the user's body-building action type during the body-building process of a person, has high accuracy, and can reasonably evaluate the movement posture of each part of the user's body.

Description

technical field [0001] The invention belongs to the field of fitness exercises, in particular to a micro-inertia-based method for evaluating the quality of fitness movements without equipment. Background technique [0002] In recent years, driven by the national fitness policy, the concept of fitness has been deeply rooted in the hearts of the people, and people's demand for fitness has become more and more vigorous.
