摘要：Oblique aerial images are becoming an increasingly popular source of photogrammetric data,and they are being acquired by more and more municipalities in Poland also. This type of imagery can provide much more information than typical vertical photographs,and many users actually see them as "more natural." The growing interest in such data is becoming apparent even at the level of national mapping agencies responsible for the development of cartographic materials in many European countries. For years,oblique photographs were perceived as supplementary data for aerial laser scanning (ALS). Often,their supplementary role was limited to providing a source of textures for 3D models developed from ALS data. They were also commonly applied in dedicated oblique images viewers, which in conjunction with a Digital Terrain Model enabled simplified height measurements of features on a single photograph. With the advancement of photogrammetric technologies in recent years,the situation has been changing,and it has become possible to accurately orientate oblique images using automatic aerotriangulation and to apply adapted dense image matching (DIM) algorithms to work with this kind of data. This paper overviews the results of orientation of blocks of oblique photographs that have been published in recent years,focusing in particular on benchmarking results obtained by EuroSDR and ISPRS for methods of orientating oblique images. The purpose of the performed experimental tests was to determine the capacity for mapping the geometry of building façades using dense image matching and for detecting changes in urban space using oblique photographs with respect to façades. The research was focused on two main issues,the first one concerning the assessment of accuracy and the second an attempt to apply oblique photographs to the detection of changes in building façades,which is not possible using any other aerial photogrammetric data.
