Simple Methods of Photogrammetry: Easy and Fast

Abstract

The need for surveying and recording the cultural property is increasing every day and is demanding proper answers from experts and scientists. The answer to such a problem must be based in the use of photogrammetry and other new technologies whose use must be widely extended. Experts in such technics are not enough in number for solving the problem. This means that they can’t take on their shoulders the responsibility of the complete task. The real problem today for the developing of the use of photogrammetry lies in training the people able to operate those systems: Architects, archeologists, art historians, curators, draftsmen and technicians in general. Photogrammetry should be promoted and taught to these professionals, not as a sophisticated and complex systems requiring costly instruments and specialized technicians, but as a methodology that is accessible today to most of professionals and which is not as costly as it was before. Photogrammetry can contribute not only with precision, but specially with speed and efficiency regarding to documentation; It is an ideal system for producing 3D models, for creating data bases, and offering efficient solutions in emergency cases, etc. There are here some examples of the use of digital photogrammetry based on systems and methods which make possible to operate reducing the working time in the site, and operating very light and inexpensive equipment. This system is specially adapted to emergency works and archaeology, when it is needed to work on field without the full support of a complete office equipment. The use of the system is actually taught to architecture students in short courses proving how easy is its handling.
