基于双目视觉的二次曲面体三维结构重建

The Conicoid 3D Reconstruction Based on Binocular Vision

该文利用空间二次曲线的投影不变性,提出一种从两个透视投影图对空间二次曲面体轮廓重建的方法。根据双目立体视觉的成像模型计算匹配边缘点的三维坐标,最后使用非线性最小二乘法曲线拟合实现轮廓的三维重建。实验结果表明,该方法能够有效地重建出空间中任意摆放的二次曲面体的轮廓边缘,较之以往的重建方法具有较高的重建精度。

In this paper,we proposed a method of reconstruction the conicoid from two perspectives.Calculate the three-dimen sional coordinates of matched edge points base on binocular stereo vision imaging model to realize the three-dimensional recon struction of the contour.The experimental results show that this method can quickly and effectively rebuild the contour edge of qua dratic surface body with higher reconstruction accuracy.
