Abstract:

The method of obtaining mathematical models and mosaic flat facade of the building, on the basis of single images is described. Images are taken at arbitrary points with arbitrary orientation of the camera. Geodetic measurements for the determination of the exterior orientation parameters of the images are not required. As a basis, at processing of each photo a rectangle formed by the selected parts of the facade, is taken. Mathematical substantiation of the method of processing images is given; the matters of accuracy of the photogrammetric model creation are considered. This technology is based on the dependence of distortion from the ratio of the focal length of the image by the main focal length of the lens.

Keywords:

questions of accuracy, deformity for the distortion, mathematical reasoning processing method, single photos, mosaic flat facade
