Abstract
The present application provides a kind of contour identification method, device, equipment and storage medium, the method comprises: obtaining target drawing to be identified;Extract all line segments in target drawing;Respectively, each line segment is extended, so that the line segment after extension can constitute closed area;Maximum ring search is carried out based on the line segment after extension, and the contour of target drawing is obtained. Thus, the area with gap in the drawing is filled by extending the line segment in the drawing, so that the line segment in the drawing can form a closed area, and then the contour of the target drawing is obtained by using the maximum ring search method, so that the contour result is closer to the overall shape of the object in the drawing, the accuracy of the contour identification result is improved, and the process is simple, fast, which greatly improves the contour recognition efficiency.
