Abstract
The object of research is a system for recognizing wheels using a laser to calculate the deformation of tires. The main problem of this research, for the solution of which it is necessary to recognize the vehicle wheels with the help of laser illumination, with the subsequent restoration of their three-dimensional surfaces is the calculation of the coefficient of deformation of the vehicle wheels. In the course of the study, the vehicle and its laser illumination are simulated using the Unity 3D system. The recognition of the laser beam and the minimization of its pixels in the wheel area are carried out using algorithms implemented in the EmguCV library (OpenCV for .NET) with empirical parameter adjustment to achieve optimal recognition quality. The software is developed in C# programming language in Microsoft Visual Studio 2017. The quality of such recognition is checked in real conditions. The results of the calculation are in accordance with UNECE Standards No. 30. The implemented algorithm for recognizing the laser beam in the wheel region of a vehicle with subsequent reconstruction of its three-dimensional surface is of independent value, since it can be used to detect any objects using a vertical or horizontal laser of different colors. These results can be integrated with the TPMS (Tire Pressure Monitoring System) information to determine vehicle traffic.

Summary
Computer vision is one of the most modern areas that use the results of many related scientific areas, such as machine learning, projective geometry, probability theory, etc. Image recognition is a complex task for a computer algorithm. The recognition of the wheels of a vehicle is realized by their illumination with a laser beam The relevance of such recognition is associated with many practical applications for analyzing their condition, in particular, determining the deformation of the tires, which was done during the research. From the physical and mechanical properties of the tire depends on the performance of the car, such as load capacity, economy, handling, patency, etc. All these indicators are determined by the value and type of deformation of the tire, under the influence of external forces
