Hello,
Thanks for your response! The fact that both cameras are based on the same core makes a lot of sense, so thanks for that insight!
I need the positional data to be able to geolocate the image pixels, so the image header was one of the first things I looked at. I used exiftool to extract the raw TIFF header from both XTR and Vue Pro R images, and the resulting files both looked very similar, in terms of layout and size. I opened up the raw data in a hex editor and both files had the same number of header data bytes, before the raw image data began. It's easy to tell the raw data apart from the header in a hex editor because the raw values are usually very close to each other in magnitude in a localized area.
Also, if the image formats were significantly different, I would not have expected FLIR Tools to be able to read the XTR images.
My hunch is that there is something that is being calculated incorrectly on my part. One thing I discovered was that the math I borrowed from other posts is not making use of the atmospheric temperature at all whereas if I change the atmospheric temperature in FLIR Tools, the temperature readings change significantly. But unfortunately, I don't know what to do with that information.
Any help will be appreciated, thanks!
Cheers,
Sid
