我们提出了一种从立体配对图像重建视网膜眼底三维形状的方法。视网膜高度的检测在许多视网膜疾病的诊断和治疗中起着至关重要的作用。然而，由于眼底的形状几乎是平面的，其三维深度范围很窄。因此，我们使用血管分叉的位置和平面+视差的方法来提供对极线几何形状的稳健估计。然后使用互信息算法执行匹配，以准确估计视差图。为了验证我们的结果，在没有摄像机校准的情况下，我们将结果与当前临床黄金标准光学相干断层扫描(OCT)的测量结果进行了比较。
We present a method for the 3-D shape reconstruction of the retinal fundus from stereo paired images. Detection of retinal elevation plays a critical role in the diagnosis and management of many retinal diseases. However, since the shape of ocular fundus is nearly planar, its 3-D depth range is very narrow. Therefore, we use the location of vascular bifurcations and a plane+parallax approach to provide a robust estimation of the epipolar geometry. Matching is then performed using a mutual information algorithm for accurate estimation of the disparity maps. To validate our results, in the absence of camera calibration, we compared the results with measurements from the current clinical gold standard, optical coherence tomography (OCT).
