Method and system for time-synchronous alignment of multi-source electrocardiosignal

Abstract

The application provides a multi-source electrocardiosignal timing synchronization alignment method and system, the method comprises the following steps: S1: adaptive multi-scale symplectic geometric mode decomposition and tensor reconstruction; S2: nonlinear multi-source timing correlation modeling based on graph connection Laplacian and normalized mutual information; S3: timing distortion correction based on smooth quasi-periodic dynamic time warping; S4: timing synchronization fine adjustment based on Riemann manifold projection; S5: joint minimization of timing synchronization error based on multi-objective optimization; S6: timing synchronization alignment result output and quality evaluation. The application does not depend on external clock reference, can realize high-precision timing synchronization alignment of multi-source electrocardiosignal, and can be applied to multi-lead electrocardio monitoring, wearable multi-sensor electrocardio monitoring and remote electrocardio monitoring scenes.
