基于二次曲线的立体视觉

QUADRIC CURVE BASED STEREO VISION

我们提出了一种基于二次曲线的立体视觉方法。在以前基于曲线的立体视觉方法中,曲线只是用于计算点的特征,从而更加容易地实现点对应。我们提出的方法以图像中的二次曲线为匹配基元,勿需点与点之间的对应,我们给出了两幅图像中二次曲线对全局匹配的准则。在匹配的基础上,给出了二次曲线重建的方法,重建的过程具有解析形式的解。此方法可以实时实现。本文的最后给出了解的唯一性分析和在真实图像上所做的实验结果。

We present a stereo-vision method based on quadratic curves. Used for computing the features of the points and for establishing the point-point correspondence between the left and theright image, we provide a closed form solution for the global matching criterion of two quadratic curves in two images and furthermore, a closed form solution for the global reconstruction of the conics in the scene. The algorithm can be implemented in real time. The proof of uniqueness and the results of experiments on the real image data are given in the paper.
