The Use of Additional Conditions in Photogrammetric Constructions

The article explores the spatial relationships and spatial patterns that appear when shooting flat rectangular objects in oblique and perspective images. The article explores a new type of spatial relationship between a feature and a spatial model. The study of relations allows us to reveal the patterns of photogrammetric constructions. These regularities can be used when transforming photographs as additional conditions. The article analyzes the spatial relationships between the lines of the object and their images in the photograph, giving vanishing points. The article shows. That the calculation of vanishing point coordinates on the image allows solving the transformation problem in a new way and reduces the requirements for the number of control points for transformation. The article analyzes the spatial relationships between the lines of the object and the lines of their images in the image. Using the duality theorem allows new formulas to transform images of rectangular objects. The applicability and limitations of this method are described.
