Orthographic Views Separation from Engineering Drawing Based on Image
Zhu Li · Jisuanji gongcheng · 2007
View separation is one of the important steps in 3D reconstruction of engineering drawing.This paper proposes a new method aiming at separating views by scan-converting all the primitives into an image,and then utilizes the continuity of the dispersal pixel in image to find the outline and the approximate minimum bounding rectangle(MBR)of each view efficiently.The precise MBR of each view is computed in graphics.Compared with other existing methods,the advantage of this method is regardless of how complex the combination of primitives and can automatically separate free numbers of orthographic views from a drawing.
