So I have datasets of radiometric JPG images from a Zenmuse XT-R (FLIR Vue) camera. These so-called R-JPG images are in essence 8-bit RGB-images - they are initially unuseable for mapping as the outputs don’t yield accurate thermal measurements.
However, these images have a 16-bit grayscale TIF-image embedded inside them. Their pixel values are numbers which can later be converted into 32-bit floating temperature values in °C.
I’ve hypothesised this workflow:
- Extract the TIF-image from the R-JPG
- Convert the TIF to PNG (as ODM doesn’t support TIFs directly)
- Apply the GPS co-ordinates to the PNGs somehow (directly, indirectly, as gcp? Haven’t done this yet, am currently on this stage).
- Process the PNGs in ODM… and hope that the outputs will retain their 16-bit values.
- Convert the 16-bit output to 32-bit temperature values afterwards (not with ODM).
What are your thoughts? How can I make this happen?
