基于灭点的三维物体重建

3D Object Reconstruction Using Vanishing Points

在总结灭点属性的基础上,提出了一种基于灭点的三维物体重建方法。首先利用灭点计算出相机的内、外部参数,在此基础上,计算出物体上各点的三维空间坐标,然后通过对物体进行绘制及纹理映射,实现三维物体的重建。实验表明,这种基于灭点的物体重建方法能够恢复场景中各点之间的位置关系,以及各线段之间的长度比例关系,满足虚拟现实系统的需要。

Based on the properties of the vanishing points, a 3D object reconstruction method was proposed. After calculating the inner and outer parameters of the camera using vanishing points, the space coordinates of the points in the object could be calculated. Through construction and texture mapping, the 3D object reconstruction was realized. It shows that this method can recover the position relation between points and the length relation between lines, and then meet the needs of the virtual reality systems.
