Are applied in machinery, civil and industrial building, and systems of technical inspection. Optical videogrammetry method is used recovery of initial coordinates of searched points marked on a studied object using recorded coordinates of centers on images of these points, formed by the input lens. Image digital procession allows determining geometrical parameters of an image in online regime and their transfer into required geometrical parameters of an object.

Videogrammetric system for industrial control of geometrical parameters of wagon wheels

Channels A and B are constructed by a scheme with crossing light sheet:

Measurement range, mm 500в500 Error, mm 0.2

Channel С is constructed by a shadow scheme:

Measurement range, mm 120 180 Error, mm 0.06 Number of radial cross-sections up to 12 Cycle duration, sec 30

Experience in development and delivery of videogrammetric systems for determination of deformations of full-scale helicopter blades, aircraft modeks at aerodynamic tests, and also shape of turbine blades during their manufacturing process is acquired Structural scheme of optical system for industrial inspection of geometry of railway car wheels
