MONITORING BY AERIAL AND TERRESTRIAL PHOTOGRAMMETRY

A photogrammetric monitoring method of structural deformation has been developed during the course of this project. The method is based on a combination of aerial and terrestrial photographs. The theoretical experimentation for formulation of computer programs has been done on mathematical models. The combination of aerial and terrestrial photographs provides a 30% increased accuracy if compared to terrestrial photographs only. Practical experimentation was done on the existing Gabion Wall and it was indicated that the achievable accuracy is 1/120,000 of the photographic distance. The method is flexible if it can be used for monitoring of any type of structure as well as for aerial triangulation. (FHWA)
