摘要/Abstract

摘要： 为便于实现平面立体的三维重构,提出一种基于正等轴测草图的重构算法。首先按面片组织轴测草图轮廓信息,通过交互指定父面,并建立各个面片之间的关系。其次对轴测草图的父面进行投影逆变换求解。然后将子面绕与父面连接的公共棱边旋转,并进行分类计算,当立体的表面积最大时,生成相应的目标形体。给出了用Matlab实现算法的关键技术和测试算例,从而快速实现平面立体的三维重构。实验结果表明了该算法的有效性和实用性。

Abstract: This paper presented a method of 3D reconstruction based on given axonometric sketching to realize 3D reconstruction of planar object conveniently．Firstly,according to the outline information of the patch organization of axonometric sketching,it establishes the relationship between all patches by interactive designated father-face．Secondly,it resolves the father-face of axonometric sketching by projection inverse transformation．Last,it rotates the child-faces around the edge linked to the father-face,and calculates them categorically when the area of the tridimensional reaches the maximum,generates the accurate target shape．The key technology and test drawings of the method realized by Matlab were given in this paper．The experiment results prove that the proposed method realizes 3D reconstruction of axono-metric sketching of general planar object with a certain availability and practicality.

Key words: Axonometric sketching,3D reconstruction,Sketch recognition,Projection transformation,Planar object
