The invention discloses an illegal building identification method and device, a storage medium and computer equipment. The illegal building identification method comprises the steps: acquiring a to-be-recognized building picture corresponding to a to-be-recognized building; graying the to-be-identified building picture to obtain a grey-scale map corresponding to the to-be-identified building picture; performing edge detection on the grey-scale map to obtain an edge picture corresponding to the to-be-identified building picture; extracting a to-be-identified building contour map from the edge picture; and judging whether the to-be-identified building is an illegal building or not according to the matching condition of the to-be-identified building contour map and the standard building contour map. According to the invention, whether the to-be-identified building violates rules and regulations is analyzed according to the matching condition of the contour map of the to-be-identified building and the contour map
