Onjuiste bereik van digitale waarden in uitvoer van Thermische Orthomosaic

Question

Ik probeer een orthomosaic te verwerken van thermische beelden gemaakt met een Workswell WIRIS Pro camera. Mijn beelden zijn in radiometrisch TIFF-formaat, en de digitale pixelwaarden liggen ongeveer tussen 5000 en 7000.
Echter variëren de digitale waarden van de uitvoerorthomosaic slechts tussen 19 en 26. Ik veronderstel dat ik een configuratieparameter moet aanpassen om de uitvoer correct te maken. Kan iemand mij helpen?<\/P>

Do those values appear to be incorrect for your project site, assuming the pixels represent temperature in degrees Celsius?   I was going to show you that you can convert temperature units to Fahrenheit under Settings

...but I assume this project is in Spain, and you'd want Celsius.  (Note if you change units, you would have to reprocess).

Were you hoping to create a mosaic showing the original pixel values, from 5000 to 7000?

Hi @FranciscoCáceresClavero,

We don't have any testing data for that specific camera model, but it sounds like it is processing for you and possibly also doing the thermal temperature calculation. In cases where a drone is not supported for thermal processing yet in Drone2Map the true ortho result will only be the pixel values. We are able to add support for new thermal cameras though so if you are willing to share the data I can take a look to see what might be going on with the processing. Please feel free to email me so we can setup a shared folder: mbarker@esri.com
