Intervalo incorreto de valores digitais na saída do Orthomosaic Térmico

Question

Estou tentando processar um orthomosaic a partir de imagens térmicas capturadas por uma câmera Workswell WIRIS Pro. Minhas imagens estão no formato TIFF radiométrico, e os valores digitais dos pixels estão na faixa de aproximadamente 5000 a 7000.
No entanto, os valores digitais do orthomosaic de saída variam apenas em uma faixa entre 19 e 26. Suponho que eu precise modificar algum parâmetro de configuração para que a saída esteja correta. Alguém pode me ajudar?<\/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

Mark
