This Project demonstrates how to read the file format used by the software infratec IRBIS (*.irb) and there cameras to store thermographic Images.
Magic File Number:
FF 49 52 42 00 49 52 42 41 43 53 IRB IRBACS
Disclaim: infratec and IRBIS are registered Trademarks. I do not have any connections to infratec and this is just a hobby project.
Be very careful if you want to measure absolute temperatures! More details can be found in my master thesis https://www.hmilch.net/h/master.html or on wikipedia https://en.wikipedia.org/wiki/Emissivity
