A method and a system for detecting a regular shape are disclosed. The method includes performing edge detecting for input image data to form an edge image including a plurality of edges; extracting, based on a set radius, edge-equidistant points whose distance between the edge-equidistant point and corresponding edges of the plurality of edges is equal to the set radius; analyzing, based on spatial distribution of the edge-equidistant points in a local window, local orientation profiles of the edge-equidistant points in the local window at concentrating points; performing, based on spatial positions, clustering for the edge-equidistant points with the similar local orientation profiles to classify the edge-equidistant points with the similar local orientation profiles into the same group; and performing, based on the local orientation profiles and the spatial positions of the edge-equidistant points in the same group, an aggregation analysis of a type of a candidate of the regular shape. |
