DJI M210 with XT2 640 30hz thermal

[Bruno28]

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.

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

Depending on what kind of shots you want I can oblige 

[eKretz]

Anything! Especially stuff that shows off the higher resolution.

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.

Enjoy!

P.S. anyone who wants to work on methods of manipulating this data in batch let me know. FLIR Tools has some absurd product limitations

Edit: 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..

for batch processing you may want to look into the various exiftool works by tomas123 found in one of the E4 threads. here: https://www.eevblog.com/forum/thermal-imaging/flir-e4-thermal-imaging-camera-teardown/msg342072/#msg342072

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).

Hice setup! But be carrefull with this uav
it'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 AGL
the drone and the $ 55,000 device it carried(geophysical stuff) was completely destroyed.

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.

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.
