Documenting cultural heritage is an important step towards the conservation and restoration of monuments. ‘Precise documentation’ in conservation works, deals with the use of techniques capable of acquiring geometry as well as texture information with high precision and integrity. Only recently orthophoto’s have been accepted and are used as a standard tool in archeological and cultural heritage documentation. By analyzing two existing software packages for orthophotograph production, we conclude that standard automatic surface modeling techniques as well as laser scanning do not fulfill the high needs of close range architectural orthophotography because of the large amount of discontinuities in the surface. This paper presents ongoing research that combines the use of laser scanning, photogrammetry and image processing to overcome these problems. The major problem lies in achieving automation and efficiency together with robustness and reliability so that the algorithms and methods can be used for a successful and economically feasible implementation in practice. ispartof: pages:473-480 ispartof: Proceedings of the 11th International conference on Virtual Systems and multimedia (VSMM2005) pages:473-480 ispartof: VSMM2005 location:Ghent, Belgium status: published |
