基于轮廓线的透视反求研究

Research on 3D Reconstruction Based on Contour Line of Product

从一幅简单的图形中,采用人工半自动提取产品的轮廓外形,利用灭点进行透视反求,把二维信息转换为三维信息,计算产品的特征点的坐标及其相对位置,进行了透视元素、基本体素到组合体素的反求研究。并利用OpenGL显示轮廓的模型,搭建基于产品多感知因素的三维重构系统框架,实现设计重用辅助产品创新设计。

A new method, is presented which is calculated to use only contour line from a single image in order to compute the dimensions of object and its pose from a single image of perspective. From the perspective view, the perspective element, basic unit, and combined unit are researched, and the correlative arithmetic is presented. The pivotal arithmetic about the fragmentary visual information is also researched. At last, handle that information through classification and synthesize, construct the body of that picture in the 3D scene.
