3D object reconstruction by point coordinates of 2D line drawings

摘要

It is a research subject in computer vision to 3D reconstruction of an object represented by a single 2D line drawing.Previous works on 3D reconstruction from 2D line drawings focus on objects with lines,plane,view,and so on.This paper mainly studies the 3D reconstruction from 2D line drawings.Besides,a new approach is proposed:it is that for the research of the point coordinates of 2D line drawings,so as to achieve the object reconstruction by the reconstruction of point coordinates.The reconstruction process includes:① the collection of point coordinates (X,Y) of 2D line drawings;② the derivation of mathematical formula about the reconstruction of the point of 2D line drawings,and calculating the corresponding point of the 3D coordinates;③ the regeneration of 3D graphics with 3D points;④ analyze error by the proportional of parallel of axonometric projection,in order to prove the accuracy of the method.
