Multi-element perception data fault diagnosis method and system

The invention relates to the field of data processing, in particular to a multivariate perception data fault diagnosis method and system, and the method comprises the steps: obtaining an initial environment image, a current environment image and a standard image of each camera, obtaining an initial perspective transformation matrix and a current perspective transformation matrix of each camera based on each adjacent camera according to the initial environment image and the current environment image of each camera and the adjacent camera; obtaining an initial reference image and a current reference image of each camera based on each adjacent camera according to the initial transformation matrix, the current perspective transformation matrix and the standard image of each camera based on each adjacent camera; the abnormal coefficient of each camera based on each adjacent camera is obtained according to the initial reference image and the current reference image of each camera based on each adjacent camera, and
