CHARACTERISATION AND ALGORITHMS FOR MONITORING THE TECHNICAL CONDITION OF BUSES BY RGB SYSTEM PARAMETERS

Abstract

The algorithms of pre-trip control of buses’ technical condition under the conditions of hypothetical application of an automated system based on video registration in ATP are considered. The authors analyse the regularities of changes in the parameters of the technical condition of buses as a function of their appearance estimated by the RGB colour system parameters. Typical examples of processing and analysing static and time-varying images are given. Initial, permissible and limit values of diagnostic parameters in RGB system are defined for separate systems of buses (external lights, tyres, windscreen). Purpose. Determination of regularities of changes in the parameters of the technical condition of buses as a function of their appearance assessed by the parameters of the RGB color system. Method or methodology of the work. The method of estimating the RGB colour parameters of the reference and actual bus images in the Adobe Photoshop software environment and their subsequent mathematical analysis was used in this work. Results. Initial values of diagnostic parameters, limits and acceptable ranges are obtained. Scope of the results. The obtained results are expedient for application at creation of the automatic system of control of technical condition of the vehicle before the trip on the basis of video registration.
