Zusammenfassung:The invention relates to the technical field of image processing, and provides a table extraction method and system, electronic equipment and a storage medium, and the method comprises the steps: determining a to-be-extracted table image; performing text detection on the table image to obtain text areas in the table image and corner coordinates of the text areas; generating a mask image of the table image based on the angular point coordinates of each text region, and performing corrosion expansion on the mask image to obtain angular point coordinates of cells in the table image; the table corresponding to the table image is determined based on the corner coordinates of the text areas, the corner coordinates of the cells and the text content of the text areas, the defects that in a traditional scheme, a table extraction method is poor in compatibility, cannot adapt to tables of various forms and is poor in extraction effect are overcome, extraction of various types of tables is achieved, and the extraction ef
