Self-adaptive electromagnetic signal curve denoising fitting method and system

Abstract

The embodiment of the invention relates to the field of oil-gas exploration electrical method data processing, and discloses a self-adaptive electromagnetic signal curve denoising fitting method and system, and the method comprises the steps: carrying out the reconstruction processing of an original data pair (xi, yi, i = 1,..., N), and the data reconstruction processing comprises the data translation, the number domain conversion, and the data compression and expansion processing; performing iterative fitting on the reconstructed data by using polynomials of different times, and judging according to a fitting difference to obtain an optimal fitting polynomial; and performing data anti-reconstruction on the optimal fitting polynomial, and performing regression to an original data form. According to the embodiment of the invention, the data multi-reconstruction technology is utilized, the morbidity of curve fitting is eliminated, and any electromagnetic signal curve can be effectively fitted.
