Beschreibung
Zusammenfassung:	The invention discloses a local weighted regression correction method and system for acceleration integral displacement. Based on the idea of a separation variable method, an acceleration time history dynamic waveform local weighted regression smoothing function and a skeleton baseline local weighted regression smoothing function are used to reduced high-frequency noise and low-frequency baseline drift of an acceleration time history, a correction acceleration time history is obtained, and an integral speed time history is obtained by integration; based on the idea of a separation variable method, a speed time history dynamic waveform local weighted regression smoothing function and a skeleton baseline local weighted regression smoothing function are used to eliminate high-frequency noise and low-frequency baseline drift of a speed time history,a corrected speed time history is obtained, and an integral displacement time history is obtained by integration; and the integral displacement time history and the pr
