I did a crude comparison of pixel temperature values in the IR PC Tool program and the TIFF raw values. I inspected images from @jmason702 as well as some from my own 640T sensor and both ended up plotting along the same regression line of y=0.0991x-270.18. Granted that these points were from...

I was told by autel robotic support that the camera mode needs to be in PiP in order to get all files (5 in total) per image capture. You should have the following files: 1) IRX_*.irg 2) IRX_*.JPG - jpeg with thermal color map 3) MAX_*.JPG - jpeg from the 8K rgb sensor 4) MIX_*.JPG - jpeg that...

I'd be interested when someone gets it working. I was looking to install the APK on the Autel smart controller.

So I sent an email to autelrobotics support and they got back to me right away asking for firmware version details. They did hint that my issue could be from insufficient cooling of the components which makes sense since most of my missing files are toward the end of the mission grid. I'll let...

I'm referring to the first reply to this thread by jaja6009 mentioning a firmware upgrade. Asking if we know if it is a firmware problem that didn't exist until a recent upgrade or if it has always been there

I'm preparing for some upcoming thermal surveys. Is this confirmed to be a firmware upgrade issue or just speculation?

Any updates on this issue? I am experiencing the same problem with my mapping missions using the 640T. The rgb sensor jpeg are all there but the related thermal files (irg, TIFF, jpeg) are incomplete.

TIFF was listed as an output option so it's good to know it is only from standard inputs.

Great. Thanks again for helping sort through the process of options for creating thermal maps. We'll get there eventually!

Good. Agisoft metashape prefers TIFF format. When you get a chance could you share the same dataset as above but exported from Thermoconverter as TIFFs?

Are you able to export the converted 640T files from Thermoconverter as TIFF format?

That's a good sign they are within the claimed accuracy for the XT709 of 3 DegC or 3% (whichever is larger). The ground truthing test would require an accurate thermal probe/device to measure spots identifiable in the images or the final orthomosaic. These spots would need to be measured at the...

I've got your 2 sets of image files. Currently working on creating orthomosaics with Agisoft Metashape and Global Mapper. Has anyone done testing with ground truthing using a thermal probe to check the thermal imagery values before and after conversion?

I'm back working on thermal mapping finally! I've been catching up on the testing you and others have been doing with the 640T *.irg files. Previously I had processed the TIFFs in Agisoft Metashape but they require a conversion equation applied to the values to get absolute temperature values...
