Reconstruction of tubes from monocular fiberscopic images - application and first results
Abstract
In many industrial and medical applications, glass-fiber endoscopes are used to acquire images from complex hollows for diagnostic and interventional purposes. For a complete exploration and understanding of a hollow cave, 3-D reconstruction is necessary. In contrast to other endoscopybased reconstruction scenarios, in our case the images are immensely degraded by the glass-fiber honeycomb-pattern. Thus, we propose a reconstruction scheme for fiberscopically obtained image sequences, which has been enhanced by a data driven preprocessing step as well as a knowledge driven post-processing step. By example of a 3-D reconstruction of a straight circular tube from monocular fiberscopic images, these extensions are analyzed and evaluated.
