Limited fault inversion method, device and terminal based on multi-source geodetic measurement data

The invention discloses a finite fault inversion method and device based on multi-source geodetic measurement data and a terminal, probability density distribution of parameters is estimated by adopting a Monte Carlo method, and a Bayesian statistical method is introduced into finite fault inversion, so that objective weights among different data sources can be deduced; the posterior probability density distribution of the output parameters can conveniently evaluate the parameter uncertainty of the non-Gaussian distribution, and the posterior probability density distribution of the fault geometric parameters and the fault sliding parameters can be estimated at the same time, and the fault geometric parameters do not need to be set in advance. Compared with the prior art, the method provided by the invention can objectively determine the weight between different data under the condition that the observation data is multi-source, solves the problem of inversion result difference caused by subjective data weight
