METHOD FOR QUALITY EVALUATION OF PHOTOPLETHYSMOGRAM

A method for quality evaluation of a photoplethysmogram is provided, the method comprising: establishing a quality evaluation model (S100): obtaining a training sample data set of a pulse wave and pulse wave quality information (S110); extracting frequency domain and time series features from the pulse wave in the training sample, wherein the frequency domain includes power spectrum information and the time series features include a correlation dimension, a box-counting dimension, fuzzy entropy, and Lempei-Ziv complexity (S120); using the frequency domain and time series features as an input of an SVM model, using the quality information as an output of the SVM model, and training the training samples to obtain the pulse wave quality evaluation model (S130); evaluating signal quality (S200): collecting pulse wave data, and extracting frequency domain and time series features (S210); inputting extracted feature parameters into the established pulse wave quality evaluation model to obtain a result of the pulse
