Surface temperature control using thermal image processing

In the paper the computerized system for the surface temperature control of the rotating cylinder has been presented. In the presented solution, an IR camera works as a source of information about the thermal state of cylinder surface for the rest of the system. The necessary image processing algorithm as a basis for a control algorithm has been developed. An algorithm for the automatic localization of the cold cylinder by an IR camera using a set of thermal markers and a fuzzy recognition algorithm was developed. It enables one to calibrate the system properly in various operating conditions.
