I have gotten this to work, but I had to assemble my own solution and it required a lot of time on my part.
There is an issue I have had with dronedeploy that I hope they fix. I am using an xtr640 on a matrice 600 with an A3 flight controller. Dronedeploy does not allow me to select radiometric jpeg as the photo type, I either have to use "manual settings" to get radiometric data, or forego radiometric data and use "automatic", which generates standard jpegs. To get radiometric photos, I have to set the camera configuration in the DJI Go app and then use dronedeploy in manual camera mode on the flight. Unfortunately, the DJI Go app is quirky and if the app has connectivity problems with the drone it reverts back to standard jpeg and radiometric data is lost. This is a serious flaw and almost rendered my thermal camera useless. I came up with a workaround that allows me to take qualitative thermal photos and stitch them together. The important thing is to use the "white hot" greyscale palette as your default palette in the DJI Go app. By doing so, you can emulate a non-colorized thermographic photo. It's not as good as having the real thing, but it's not bad either and can show temperature deltas really well once the greyscale orthographic map is colorized. I have the system generally working at this point. Last night, I was able to process a 388 photo flight into a thermalish orthomap in about 3.5 hours. A thumbnail with some very poor (default) colorization applied is below:
So, it is possible but it's not easy. Just a note, you are flying way too late in the day for good thermal photos. You want to capture temperatures when the delta is highest. Early to mid morning is best after the sun has started warming the ground but before the ground temperatures have evened out. Lastly, the geotags are important in mapping. If the photos do not have geotags, then you won't really be able to create good maps. Make sure that the photos from the Inspire are properly geotagged.
