Hi,

RBF is a simple aproximation of the Planck's law. Please compare them. Both of them are using exp function. I am on holidays and can not check it, but probably more information about RBF model can be find in X. Maldague book "Theory and Practice of Infrared Technology for Nondestructive Testing". Next week I can check it for you after returning home.

Best regards,

Javier de Lucas Veguillas

Thank you very much:-)

The sakuma-hattori aproximation is more familiar for me. It's used routinely for calibration of radiation thermometers. I'm beginner in thermography and I'm not sure if the RBF model is equivalent to sakuma-hattori (alternative I mean)

best regards

Give me please more information about sakuma-hattori model. I will try to discuss and compare it with RBF model.

a very useful information explaining the use of sakuma.hattori equation for radiation thermometers (industrial type), can be found in the link below

http://www.measurement.govt.nz/sites/all/files/training-manuals/tg22-july-2009v2.pdf

In my opinion both models are good. The quality of approximation, of course, will depend on matching the coefficients that can be found by nonlinear regression. For example the RGB model were applied commonly by FLIR in ThermaCAM IR camera series. In attached file you can find the details how to calculate temperature using RGB model.
