The proposed method is less time consuming, since the microscope is needed only for obtaining the image of the measured object, as established of the object-micrometer or images of the Goryaev camera grid. Working with a scale ruler and an image is more comfortable and less difficult than working with a microscope, an ocular micrometer and a coordinate microscope table. Working with an image, unlike working with a microscope, is convenient for people using glasses as it reduces the burden on the researcher’s vision.</p
