Abstract

The invention discloses a measurement method of thigh moving posture based on MIMU / sEMG fusion, and the measurement method includes the following steps: acquiring angular velocity and acceleration information of thigh motion at least; acquiring surface electromyography (sEMG) information of thigh muscles; carrying out inertial navigation solution on the angular velocity information and the acceleration information according to the principle of inertial navigation, carrying out feature extraction on the sEMG information, using the way of machine learning to construct a prediction model of sEMGinformation-thigh rotating joint angle with the combination of the angular velocity information, introducing the thigh rotating joint angle information output from the sEMG information as the externalobservation information, and constructing a Kalman filter estimate model based on external observation feedback compensation. The invention also discloses a thigh moving posture measurement device based on MIMU / sEMG fusion. The device is simple in overall structure, high in intelligence degree, low in manufacturing cost, easy to wear and conducive to large-scale popularization and use.

Description

technical field [0001] The invention designs a thigh motion posture measuring device, in particular a wearable thigh motion posture measurement device with a simple and reliable structure and a high degree of intelligence, which can be applied to the field of sprint training. Background technique [0002] The measurement of the thigh movement posture for sprint training refers to taking the thigh as the research object, and obtaining the movement posture information of the thigh during sprint training through measurement means, including the movement posture, movement angle, force, acceleration, spatial position, and myoelectricity of the thigh. Signals, etc., by analyzing the above motion posture parameters, the athlete's thigh movement law during sprint training is obtained. This process is an indispensable testing technology for obtaining human motion posture. It has a wide range of applications in the fields of gait monitoring, smart medical care, and sports training. ap...
