A visual 3D retinal model could facilitate the process of disease diagnosis. We have studied 3D retinal surface reconstruction by using the affine camera due to the narrow field-of-view and the small depth variation in each field. We have proposed the affine bundle adjustment algorithm, which refines visual reconstruction and camera parameters simultaneously. Moreover, we have developed a new 3D reconstruction algorithm that incorporates the retina’s geometric constraint and the radial distortion removal into the optimization process of bundle adjustment to further improve the quality of 3D retinal curvature estimation.

Examples of 3D retinal curvature estimation.
