3D Solid Reconstruction from 2D Orthographic Views

Abstract

Three-dimensional computer-aided design (CAD) models are widely used by designers because of their useful applications in the areas of CAD/CAM/CAE/CAQ. A desirous trend to create this model, which has long been studied by scientists around the world, is a 3D model reconstruction from 2D orthographic views. With this method, it is easy to enter geometric information as well as use 2D drawings that have already existed. Most of the previous works used three views, but many of the mechanical parts needed only two views. An advanced 3D solid reconstruction system using only two orthographic views is the subject of this chapter. The proposed method has been implemented and verified reliability by an ObjectARX program plugged into AutoCAD 2018. The 3D models have been checked for their compatibility with 3D CAD/CAM systems. This chapter presents principles, algorithms, databases, programming for the advanced reconstruction system, and some of its technical applications.

A reconstruction algorithm of engineering drawings of two-dimensional keyway shaft parts

“…Since Idesawa [3] first proposed the three-view 3D reconstruction method, 3D solid reconstruction research based on mechanical engineering drawings has attracted extensive attention in the field of computer application research. At present, 3D reconstruction methods for mechanical engineering drawings are mainly categorized into [4] wireframe-oriented reconstruction methods [5,6] and volume-oriented reconstruction methods [7,8] . This paper focuses on solving the problem of 3D solid reconstruction of keyway shaft parts, whose existing solution methods mainly use volume-oriented 3D reconstruction algorithms.…”
