alot of area missing photos, unless they did not all upload into drop box. 90/90 is alot, but PIX4D requires it.

trying to process now

I agree. That is what was captured. I have never flown at 90/90. 200' AGL is low as well. I generally fly 250' AGL or higher and 80/80. With my 6K camera, never had this kind of problem. Flight lines were not true either. I have flown this same areas at least 100 times but not with this camera setup and to these specs. Below is what the thermal IR survey looks like in Correlator3D.

Do you happen to know the pixel size for the XT706 1/2" CMOS 8K Visible Camera? The Effective Focal Length (EFL) is 25.6 mm.

I have PIX4D Discover, anyone have the real pix4D mapper that can try to process the 640R data sets

its 48 MP, but not wile mapping, I can process that also and let you know

PIX does not recognize the camera type, for some reason. I am weak in the thermal mapping world. so hoping other guys can look into processing

click the drone deploy link to view map, no temp data, because I do not have enterprise plan, but it worked. Also, did you have an RTK fix during this mission?

I have uploaded to Drone Deploy. I have access to the Enterprise plan. I will share when its done.

I am working on an Agisoft non-radiometric processing. The files would need to be converted to tiff for Agi to work with them.

in his file set, there is a folder that reads converted, inside there are tiffs. this seems interesting... can you use these in AGI

I shot another thermal survey this morning. See link to Dropbox folder below. Below are the specs (different from yesterday). Still a lot of missing images. Any ideas why? I have reported to Autel and Advexure.

06-01-22
RTK-Corrected
Thermal Images Only
SanDisk Extreme PRO 256GB MicroSD card
250’ AGL
80%/80% Overlap
7 mph speed
Weather generally good. Occasional clouds and little wind.

I processed a quick and dirty thermal map in SimActive Correlator3D. Below are a couple of screen captures showing the 2D Ortho and Thermal Map.

will process, can you try the iron bow color pallet next time? also was this a RTK flight?

I will change to iron color pallet using FLIR Thermal Studio. See attachment. Yes, RTK flight.

There was an issue with the 640R stalling out on photos, is was supposed to be fixed, and to a good degree, it was, but looks like there is some more fixing to do...

WIll do, I will run them now that I am home from work.

Here are the Drone Deploy results. I used the R.JPEGS. It stitched together pretty well and the radiometric data seems to be pretty good, but I think more testing would be needed with different items.

FLIR Tools measurement, Spot = 107.9 *F and Hottest is 108.4

Drone Deploy below. It did not stitch this item together that great though.
