Abstract

The invention aims to provide a system and method for identifying surface electromyogram signals, and the method comprises the steps: collecting surface electromyogram signals of multiple parts of a human body, carrying out the specified preprocessing of the surface electromyogram signals, determining the surface electromyogram signals after the specified preprocessing, and storing the surface electromyogram signals after the specified preprocessing; on the basis of a preset feature extraction model, performing feature extraction processing on the surface electromyogram signals obtained after specified preprocessing, and determining a target feature matrix; and performing identification processing on the target feature matrix, and determining a target action category. Therefore, reliable and stable surface electromyogram signal data are collected in real time, the surface electromyogram signals are accurately represented through multi-channel data fusion wavelet packet principal component analysis, and the accuracy of user limb movement recognition is improved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a system and method for identifying surface electromyographic signals. Background technique [0002] At present, the surface electromyographic signal is of great significance to the muscle rehabilitation project of the disabled, the muscle training project of athletes, and the control application of intelligent prosthetic limbs and intelligent wheelchairs. In view of the non-stationarity of surface electromechanical signals, it is difficult to effectively obtain the characteristic parameters of surface electromechanical signals in the existing surface electromechanical signal recognition methods, and the dimensionality in the calculation process is too high, and the feature accuracy extracted after dimensionality reduction is low. The recognition rate is low. Contents of the invention [0003] One purpose of the present application is to provide a system and method for ident...
