Abstract
A system of contactless gun barrel straightness inspection by the structured light method is developed. A design of a compact optical probe, in which a diffractive optical element is used for gun barrel illumination, is proposed and developed. Algorithms for processing of images obtained by means of gun barrel scanning are presented; based on processing results, the 3D shape of the controlled product is retrieved and required geometrical parameters are calculated. Results of the contactless gun barrel straightness inspection system testing by using actual product samples are presented.
