提出了一种从两幅未校准的眼底图像中恢复视网膜视盘三维结构的新方法。在临床上获取视网膜图像时，通常未进行校准，这造成了矫正挑战以及立体对内部显著的辐射和模糊差异。通过利用视网膜的结构特点，我们对目前最先进的方法之一--Graph Cuts计算立体方法进行了改进，得到了一种高质量的眼底立体重建算法。在我们的数据集和公开可用的数据集上进行的广泛的定性和定量实验评估(其中OCT扫描被用作3D地面真实数据)表明了所提出的方法与其他替代方法相比的优越性。
This paper presents a novel method to recover 3D structure of the optic disc in the retina from two uncalibrated fundus images. Retinal images are commonly uncalibrated when acquired clinically, creating rectification challenges as well as significant radiometric and blur differences within the stereo pair. By exploiting structural peculiarities of the retina, we modified the Graph Cuts computational stereo method (one of current state-of-the-art methods) to yield a highquality algorithm for fundus stereo reconstruction. Extensive qualitative and quantitative experimental evaluation (where OCT scans are used as 3D ground truth) on our and publicly available datasets shows the superiority of the proposed method in comparison to other alternatives.
