Multi-physic calibration for coupled IR Thermography - Stereo DIC sensor: from target to software
Résumé
Acquiring rich multi-physics data is becoming essential for characterising thermo-mechanical constitutive relations. Stereo Digital Images Correlation and Infra-Red Thermography sensors can be coupled for this purpose but need to be calibrated. This paper presents a multi-physics calibration method. It is based on a laser marked bi-spectral target pattern and uses a (2+1) calibration algorithm to characterise the parameters of the camera model.
