Reconstruction on a photo of architectural monuments containing a rotation surfaces

The relevance of the reconstruction of architectural monuments is obvious. It is enough to note that entire cities were restored after the world wars in their original form. For the preparation of restoration projects, various sources are used, including archival photographs. Therefore, new methods of metric processing of photographs are important. There can be no general method for reconstruction of photographs, since it depends on the number of pictures, the shape of the depicted objects, and many other conditions. The special case is reconstructions from a single photograph. A single image without additional conditions determines neither metric nor positional properties of space. However, depending on the latter, you can determine the shape, size, data about the projecting apparatus and their relative position., An image of a single surface was used, to reconstruct images from sketches of projections of surfaces of revolution and the missing information was made up from combinations of various conditions of a different kind superimposed on the photograph of the object. Purpose. To develop a method of geometric reconstruction from a photograph of an object containing a number of surfaces of revolution that do not overlap, based on the use of the coordinates of points on the sketches of the projections of the surfaces, which will allow to reveal the "sketch method". Conclusion. The proposed method for reconstruction of photographs allows using in maximum the information contained on them and, in combination with other methods, makes it possible to determine the values of the desired values and evaluate their accuracy. Metric processing of photographs makes it possible to eliminate the stage of prototyping for reduction of the cost of projects restoration.
