从正交视图自动生成三维模型，利用角点投影求交构建表面。
3D Architect: An Automated Approach to Three-Dimensional Modeling
- 通过霍尔里斯角点检测获取控制点，垂直投影形成包围体。
- 交集点构成三维点云，重建物体表面并渲染输出。
- 适合自动化三维建模需求，无需复杂参数调节。
本文旨在利用一组物体的正交视图实现其三维重构。首先在输入视图上应用霍尔里斯角点检测器提取控制点，将这些控制点分别垂直投影至对应视图平面，构建出相互垂直的包围体。通过计算这些包围体之间的交集，获得描述物体三维结构的点集。利用计算几何方法，基于该点集重建物体表面，并最终通过OpenGL进行三维可视化渲染。本方法实现了从二维正交视图到三维模型的自动转换，为自动化三维建模提供了一种可行路径。
原文摘要 · Abstract (English)
The aim of our paper is to render an object in 3-dimension using a set of its orthographic views. Corner detector (Harris Detector) is applied on the input views to obtain control points. These control points are projected perpendicular to respective views, in order to construct an envelope. A set of points describing the object in 3-dimension, are obtained from the intersection of these mutually perpendicular envelopes. These set of points are used to regenerate the surfaces of the object using computational geometry. At the end, the object in 3-dimension is rendered using OpenGL
