Hello there,
I am working with some SC660 Flir images on exiftool and i have some questions about the information extracted on the program:
1 - What is the physical definition of the parameters R1, R2, F and O. Are they just an aproximation of the Plancks Law for blackbody radiation?
2 - exiftool(-k) returns some raw values tagged as: Raw Value Range Max and Raw Value Range Min which leades to the interpretation that they are the values for the range of operation. However, when I convert them to temperature, it returns 150 and -60 but the range of operation is 120 -40. What does that mean ? Could it be that the range of operation is indeed -40 120 but the saturation points are -60 150?
Thank you.
I have no knowledge of Flir images, but in case you haven't seen them, there's the FLIR tag page (https://exiftool.org/TagNames/FLIR.html) and this forum post (https://exiftool.org/forum/index.php?topic=4898.msg23972#msg23972) which might have some answers.
Yeah, i've seen both links but they don't really explain the meaning of the values/tags.
Thanks for the reply.
Regarding R1, R2, F and O, I'm not an expert on it, but tomas123 had a whole series of posts on these parameters starting in the 2016 time frame. Probably should look at those posts.
Edit: I see those posts on FLIR tags go back as far as 2013.
Another place to find this info is on the EEVblog Thermal Imaging forum: https://www.eevblog.com/forum/thermal-imaging/
Again many posts by tomas123.
I think that's what I linked to above.
