Abstract
The methods of computer vision allow the 3D-reconstruction of an object from 2D stereo image pairs. The EU-Project Glaucad studies the glaucoma disease regarding appropriate geometric characterizations. Our task within this project is to develop a module for automatic 3D-reconstruction of the ocular fundus out of the uncalibrated stereo images. These reconstructions will be used to analyze the changes of the ocular fundus of glaucoma patients. Using methods of computer vision two main demands turned out to produce precise results: A good image preprocessing to compensate the partly changing and difficult recording conditions and a precise registration as prerequisite for the later calculation steps.
