Grounding grid topological structure image reconstruction method and system, storage medium and equipment

The invention discloses a grounding grid topological structure image reconstruction method, which comprises the following steps of: acquiring original magnetic data and positioning data of discrete measurement points on the ground surface of a grounding grid to be measured, and preprocessing the original magnetic data according to the positioning data to obtain preprocessed magnetic data which is grid data; performing feature point extraction on the preprocessed magnetic data, and recording position information of the extracted feature points to obtain a grounding grid topological structure feature point diagram; filtering the grounding grid topological structure feature point diagram to obtain a filtered grounding grid topological structure feature point diagram; and converting the filtered grounding grid topological structure feature point diagram into a parameter space through Hough transform, identifying line segment information in the feature point diagram through clustering analysis in the parameter spa
