공학용 도면에서 object와 dimension sets의 분리 추출에 기초한 치수선의 벡터화 = Vectorization of Dimension line based on extraction of Object and Dimension Sets in Engineering Drawings

다국어 초록 (Multilingual Abstract)

A general engineering drawing is composed of the object representing orthographic projection of 3-D element and dimension sets which provide exact definition of the object. This paper proposes the method that extracts and vectorize dimension line in mechanical drawing. To solve the complexity of the conventional method which traces dimension lines to be connected to them after detecting arrowheads, we separate the object and dimension sets by using the morphological operation. And, using line vector extraction and line vector clustering, we vectorize object and dimension line, In this vectorization process, broken dimension line is reconstructed. Experimental results which apply the proposed method to the drawing drawn to KS drafting standards are presented.
