Abstract
Lack of standardization and lack of funding are the major reasons for the fact that close-range photogrammetry did not obtain the prominence which one could have expected. Actually, we focus on a new era of photogrammetry, which may be characterized by digital procedures both for data acquisition and data processing. These techniques will definitely change the present status of architectural photogrammetry. Applications for the analysis of deformation depend very much on the magnitudes of deformation and the necessary observation period. A typical task is the control of construction elements under load. If civil engineers provide theoretical deformation values, the latter have been confirmed by photogrammetric methods. In this case even nonmetric cameras may be used successfully. For large structures metric cameras are recommended, combined with rigorous analytical adjustment procedures. For close range applications, special software programs are available (e.g., CRISP, BINGO), which allow phototriangulation together with specific restrictions.
