@article{(Open Science Index):https://publications.waset.org/pdf/7236, title = {A Stereo Vision System for Top View Book Scanners}, author = {Erik Lilienblum and Robert Niese and Bernd Michaelis}, country = {}, institution = {}, abstract = {This paper proposes a novel stereo vision technique for top view book scanners which provide us with dense 3d point clouds of page surfaces. This is a precondition to dewarp bound volumes independent of 2d information on the page. Our method is based on algorithms, which normally require the projection of pattern sequences with structured light. We use image sequences of the moving stripe lighting of the top view scanner instead of an additional light projection. Thus the stereo vision setup is simplified without losing measurement accuracy. Furthermore we improve a surface model dewarping method through introducing a difference vector based on real measurements. Although our proposed method is hardly expensive neither in calculation time nor in hardware requirements we present good dewarping results even for difficult examples.}, journal = {International Journal of Electronics and Communication Engineering}, volume = {3}, number = {11}, year = {2009}, pages = {1916 - 1921}, ee = {https://publications.waset.org/pdf/7236}, url = {https://publications.waset.org/vol/35}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 35, 2009}, }
