Diagnostics of a vehicle chassis allows for the evaluation of the technical state of components that significantly affect the travelling safety. Special diagnostic lines in the form of complex devices equipped with computerized inspection systems are used during periodic vehicle diagnostics. Both the trucks (belonging to the high-risk group of fault occurrence) and public transport vehicles need frequent and rapid inspection of their condition for safety reasons. Vision systems are suitable for automatic inspection of the vehicle chassis without any need for stopping during the testing. In most cases, systems with standard visible light or infrared cameras are used for automatic inspection of the technical condition of the brakes, bearings, and tires in trucks. Hybrid vision methods combining the advantages of both measurement techniques are also applied in railroad chassis inspection to assess the condition of the braking system, bearings and electrical systems, to detect failures, or to identify damaged or missed parts. A hybrid vision inspection method for vehicle chassis with a measuring head equipped with 2 cameras was described. One camera observes in the visible and another observes in the infrared wavelength regions. Exemplary results of tests performed on large-size vehicles used for public transport are presented. Both the advantages and limitations of the proposed method are given.
