Thermal support for DJI M3T [WIP]

[pierotofy]

Started adding thermal support for the DJI M3T, but it's not clear how to
interpret the raw thermal data information.

This is being investigated at
https://exiftool.org/forum/index.php?topic=11401.45 as well.

Per the request on the forum, here is a link to some files for testing and calibration of the Celsius values.

The folder contains a sub-folder with images taken using a Mavic 3T, and an image in the main folder showing the results, along with temperature ranges, as processed in another system.

Hopefully, that helps move things forward.

Thanks for all you do!

Hopefully, that helps move things forward.

I downloaded these, so if they are needed after the link expires, I have a copy. @aviosmedia -- can you share the final tif dataset from the other software. The screenshot is helpful, but being able to interrogate the final raw values might be helpful.

Thanks so much for sharing quickly.

Hi - I added another folder to the same link with the tif files @smathermather so you can download again (or just download the new files).

Hopefully, that gives you what you need.

Thanks!

Is there a solution to this problem?
I remember I opened a topic in the WebODM community and also added some data as an example.

Not yet. This is a large undertaking, unfortunately.

Hello everyone,

@pierotofy @smathermather I haven't been using ODM and WebODM for very long. However, I've been following this topic for some months now.

Would it work to convert the images to TIFFs and copy the metadata afterward? I have seen several people doing it this way and saying it works for them. Most of them use DJI SDK to convert the images from DJI Mavic 3T to TIFF.

I'm not an expert in this, but depending on what you think, I could try it out.
