Abstract

This work describes a temperature and emissivity measurement methodology that applies the multi-wavelength pyrometry principle to IR thermography using two IR cameras in a stereo arrangement with detectors working in different wavelength bands. The two radiation distributions measured by the IR cameras are rebuilt on the object surface mesh by means of the pinhole camera model and are used to write a system of equations in which emissivities and temperatures are unknown quantities. By solving the system, the temperature and directional emissivity of the material under test can be measured for each wavelength band.
