Hi, I'm hoping Sam reads this. We are working with some scientists in Victoria BC Canada, on a project to monitor underwater noise and ship traffic to help killer whale habitat. If it's possible to contact you, or just ask questions here, that would be great. We have a Flir A65 that we want to capture images from on a raspberry Pi, and so far this is the best example code I have found. I'm hoping I can find out how complete it is and if it worked fine for you. thanks!

Hi Sam, I got it to work, just had to do adjust the makefile and change the hardcoded camera value. I really appreciate you putting the code up, thanks!

I don't remember much in detail, but this was meant to be used for thermal imaging. One of the problems I had was that the Flir A65 had an automatic intensity scaling, so images were already normalized.

I was unable to work out how to get the camera to communicate what the mapping between greyscale pixel intensity and actual recorded temperature was. There didn't seem to be any relevant command. I also couldn't force the camera to use a manual temperature to intensity mapping or turn off the normalisation.

I was convinced it should be possible, since there were closed source windows applications using the camera to show a live feed that included a colour/temperature map bar, but I couldn't find out how to do it.

That was a pretty big blocker since there was no way to know what the exact temperature imaged was, and I had to give up on the project. I considered various impractical solutions like having a known fixed temperature source in the image.

If you end up finding the same problem and have a solution please post it.
