content: Look what I get to play with this week. Just a loan from the business. We are demoing this to Fire Fighters in Australia.I did a quick test and it's quite cool. 640x512 resolution at 30hz with a 19mm lens. It will be even better when flying.Just wanted to share something different in the thermal camera world.Sent from my SM-G960F using Tapatalk

content: Nice, post some more if you get some airborne shots.

content: I removed some of the identifying EXIF data for obvious reasons but beyond that I tried to keep them as original as possible so you can mess around with the data.https://www.dropbox.com/s/2t2zf54zu8ld06y/Thermal%20imagery.7z?dl=0Enjoy!P.S. anyone who wants to work on methods of manipulating this data in batch let me know. FLIR Tools has some absurd product limitationsEdit: I left out some information, the camera is a DJI Zenmuse XT (Tau 2 core?) with the 640x512 resolution, 13mm lens, and radiometric options. Camera cost is around ~10k USD.Oh, there's a dead pixel that's being looked at right now in the pictures. We're annoyed it failed after less than a year of use, and of course the warranty is 6 months. Hoping the fix isn't too expensive..

content: for batch processing you may want to look into the various exiftool works by tomas123found in one of the E4 threads.here:https://www.eevblog.com/forum/thermal-imaging/flir-e4-thermal-imaging-camera-teardown/msg342072/#msg342072E: added link

content: Ah yes I remember that tool, very cool. I need to look further into using it for the method I mentioned. I'm unsure of what FLIR tools does to auto adjust the picture but it works well. The color distribution options are also nice (linear, signal, histogram equalization).

content: Hice setup! But be carrefull with this uavit's a great drone especially with new remote it has a strange power problem, you can find various crash reports online.Our brand-new matrice 210 overheated on flight and crashed to the ground while flying 150m AGLthe drone and the $ 55,000 device it carried(geophysical stuff) was completely destroyed.

content: Regarding a dead pixel -- the pixel at X=531, Y=287 seems not to be working on the images I looked at. I come up with a nan (not a number) for the temperature at that pixel. Also, there doesn't seem to be a palette in these image files.

content: The XT2 has to be one of the worst put together cameras going. DJI took the approach of building their own thermal imaging payload based on the Tau2 - they didn't use any of FLIR's SDK. Consequently, every 1 out of 2 XT2s 640x512 with 13mm lens are poorly calibrated and have crazy temperature differences of ~10 degrees from the centre to the edge. It takes DJI over 4 months to get it solved EVERY TIME.That said, when they work, they can be very effective.
