摘要：Historical maps are an essential documentary heritage for the knowledge of ter-ritory. Digitization, in the case of old maps, cannot be a simple high-resolution two-dimensional scan, but it has to detect the geometry of the supporting material.This work describes part of an on-going project, developed by the Laboratory of Photo-grammetry of IUAV University, concerning the study of different methodologies and tools for the 3D digitization of old maps. In particular, high-resolution cameras, combined with a mechanical positioning system and appropriate software for the rigorous construction of “mosaics”, will be explored as a potential means of replacing the expensive large format flatbed scanners. The research aims to digitally record the shape of maps, not only consid-ering their semantic content (printed image), but also their three-dimensional surfaces, and their subjection to time and deformations. Through the development of new algorithms, procedures and mechanical properties, it will be possible to obtain a rigorous three-dimensional geometric memory of the original cartographic heritage.
