| 摘要: |
| 研究了从物体二维照片重构其三维CAD模型的算法。通过物体在不同方位的一组照片，选取一定数量的配准点，该算法能够计算出照相机的运动参数，进而得到物体表面的3D几何信息及CAD模型。算法充分考虑到了CAD建模的可制造性约束，具有精确、稳健的特点，在逆向工程建模、计算机视觉、机器人领域有应用前景。 |

| Abstract: |
| This paper makes an investigation on the algorithm of reconstructing a 3-dimentional CAD model from 2-dimentional photos. By a set of points picked on an object's 2-dimentional photos taken in different direction and position, the movement parameters of the camera and the 3-dimentional geometric information and CAD model of the object can be calculated with the algorithm. The algorithm makes sufficient considerations on the constraints of manufacturablity in CAD modelling, is accurate and robust, and will be useful in the fields of reverse engineering, computer vision and robots. |
