Projection-based coupling of infrared thermography and stereocorrelation-based digital image correlation
The study proposes an external projection-based coupling method to link two different measurement techniques: infrared thermography and stereocorrelation-based digital image correlation (DIC). This method uses a pinhole camera model, calibrated by a reference object, to relate 2D temperature data from IRT to 3D point coordinates from DIC. This allows for the accurate representation of temperature fields on curved surfaces and enables the calculation of in-plane temperature gradients and rates.
