Photogrammetric methods are widely used for non-topographic purposes and, in particular, in construction to determine deformations of engineering structures. A number of works devoted to this topic have appeared in recent years and some experience has been accumulated in this field. However, researchers often either copy the methodology and principles of aerial photography, which complicates and complicates the necessary calculations, or simplify the method to such an extent that it becomes suitable only for architectural measurements or for determining large absolute values of deformations (2- 3 mm).
