Currently, to study the shape, size, deformation and movements of various bodies, their perspective photography is widely used, which served as the beginning of a number of new sciences, such as aerial photography and filming. This work is an introduction to the theory of the mentioned methods and contains elements of measuring perspective , i.e., solving metric problems in perspective. In addition to the specified practical goal, the methodological goal of the work is to use the coordinate method to systematically solve the main problems of descriptive geometry using the conical design method. In accordance with the above, this work is divided into two parts: the first includes the basic principles of the conical design method and methods for solving metric problems, and the second contains a number of solutions to typical examples that can be used in presenting a course in descriptive geometry.
