Large-scale mapping of multidimensional structure parameters in free space

摘要

In a process for large-scale mapping of parameters of multidimensional structures in a natural environment, aerial survey photographs of the natural environment or regions thereof are taken during first photographic surveying flights at a flight altitude of approximately 150 to 500 m above the ground using reconnaissance cameras (2) in combination with telelens cameras (3). Detailed photographs of the section of the region covered by the reconnaissance cameras (2) are obtained from said aerial survey photographs. The aerial survey photographs are identified in terms of their position in the natural environment by means of orientation devices and evaluated using photogrammetric methods. The recorded data concerning the natural environment of a structure are allocated to the co-ordinates of the structure in the natural environment and can be accessed as desired.
