一种利用单张影像进行规则物体三维重建的方法

3D Reconstruction Based on Vanishing Point Principle from a Single Image

提出了一种以单张影像为基础,基于灭点几何原理、共线条件方程及共面约束条件,进行规则物体三维重建的方法。该方法通过影像中的3条两两垂直的直线,利用灭点几何原理得到了影像的方位角元素;利用解算的角元素及共线方程得到了摄影中心坐标;最后,利用解算的影像外方位元素及共面约束条件得到规则物体的三维几何模型。

This paper implements 3D reconstruction of the regular object based on vanishing point principle, collinearity equation and cuplanar constraints from a single image. It gets exterior angle elements with the three mutual vertical lines based on vanishing point principle. Then it gets the relative position of the photography center with exterior angle elements based on collinearity eqnaticm; At last, it gets the coordinates of some especial points with the exterior elements of the images and restricting condition of man vision.
