Thermo Vision Camera Space Calibration Method in Area of Mobile Robots Observation

Abstract: The existing popular methods of thermo vision camera calibration are for temperature range adjustment using reference temperature sources and test thermal images. Correct temperature calibration of a thermal or infrared camera allows the inspector to be certain of the temperature measurements presented in the thermal images given from a calibrated thermal or infrared camera. Also in each thermo visual images processing method is very important to use temperature calibration of thermo and infrared cameras as sources of thermal images. Here is proposed a space calibration method for the thermal or infrared camera. The space calibration is of superior importance in applications where thermal or infrared cameras are applied for 2D or 3D thermal objects localization and their position calculation, for example when a mobile robot detect and determine the position of thermal objects in area of observation. The proposed in this article space calibration method for thermal or infrared camera is presented first with a theoretical model, described as algorithm and then tested for a concrete mobile robot application.
