Abstract
The work is devoted to the problem of determining the ovality and distortion of the profile of pipes and other parts of a
cylindrical shape with diameters from 1 to 2 meters when accessing only the external surface. Existing methods for determining
diameters and ovality of parts was carried out was analyzed. To solve the problem, a valid prototype of a measuring
device with hardware and software was developed. The mathematical algorithms were also using a software-implemented
simulator are proposed and tested. The results of tests on a natural bench with the possibility of open access to the section,
which made it possible to ensure the verification of the obtained data by direct measurements, are presented. It was
revealed that the existing methods for measuring ovality of large diameters from the outside do not allow to determine
distortions of the profile with high accuracy.
