Abstract
The article discusses the development of a non-contact straightness inspection system of the rifled guns channels based on the structured light method. A compact optical probe has been developed, in which a diffractive optical element (DOE) is used to illuminate the bore. Algorithms for processing a series of images obtained by scanning a bore are proposed and developed. In the issue of image processing 3D form of the controlled product is reconstructed. The test results of the straightness inspection system on real samples are presented. As a result of the tests, the error of measurements of straightness deviations at the level of ± 4 microns was obtained.
