During the control of technological processes of manufacturing various parts, which are required to increase the accuracy of processing, it is necessary to adhere to the systematic measurement of their geometric dimensions, tolerances, compliance with the shape and location of the surfaces of the parts. To date, this type of non-destructive testing is carried out using special optical systems and allows you to study different products, regardless of their type, design features and structure of the materials from which they are made. That is, the visual-optical method of measurement is one of the most important methods of non-destructive testing in production.
 In the article the authors shared practical experience in the selection and optimal use of 3D video measuring system with limited resources. The choice of manufacturer and model (type) of video measuring system was made depending on the complexity of the measurement tasks. First of all, the error of measurement results was evaluated, which was determined by technical indicators and the composition of software functionality. For control in the manufacture of high-precision mechanical parts, the basic requirements for technical parameters and software of the video measuring system are defined.
 Emphasis is placed on the economic effect by reducing the time of measurement of linear dimensions and angles in the plane of the controlled parts, while using high-quality functionality of video processing, which significantly reduces the likelihood of operator error. The choice between manual and automated measurement systems is justified: the main factors are the capacity and the required amount of measurements. Evaluated as a positive ability to save information files in Exel, Word, and SPC for statistical processing of information to improve the quality of parts.
 Features of video measuring systems concerning: implementation of innovative metrological solutions - multisensory metrology, namely - inclusion in the program of measurements of optical, laser and contact research; Reverse Engineering of previous versions of parts for which drawings have already been lost and CAD models are not available.
