Hello dpoursanidis,
regarding your parallel collection with RX100, does that mean that u are capturing both RGB Sony RX100 and Infrared Optris PI640 images on same platform?
If so what is the focal length of your RX100? If it is set at 10.4 mm then the following parameters would result from a capture at 65 m AGL with 80% front and 65% sise overlap for Infraredimagery see attachment...
As you can see the resulting GSD for the 2 sensors is very different (10.5 cm for Infrared Thermal vs 1.5 cm for Sony RGB sensor). So it would make sense to process the 2 image sets in 2 different chunks and use the georeferenced RGB set to extract CPs to georeference the Thermal set...
Again if you can share a small sample with 2 sets of images (RGB and thermal) then we could have a look at it...
Thanks for that detailed insights and the calculations.
Here (
ftp://ftp.iacm.forth.gr/incoming/DP/OPTRIS_SONY_TESTdata/) you can have access to geotagged imagery from both cameras.
The mission planning will be based on the parameters of the Thermal Camera, since we intend to collect data in cities (if and when we will have the permissions to operate) and create a complete 3D thermal cube for the selected areas.
Meanwhile, is the excel file available for reuse?
