![]() calculate the Range (max-min) and change the span value until your image has the same range in the Thermovision (the range is noted in the Scale bottom). You have to setup them following: take a image with a big temperature range. for a dynamic calculation there are Level and Span values. the temperature of the tif files have to setup manually by choose "fixed". after that you can easy Drag & Drop your *.tif, *.tiff,*.csv Files. if you change the Filedrop mode to "Drop-> Optris PI400 Mode" (in "Datei" or "File" if you set Language to EN). Hello, i have a new Version of my Thermovision including some Optris Pi400 stuff. All steps in one line with expanding the level for visual examination: The data sheet of PI 400 give us a range from –20 ☌. Maybe we need an sample image with higher temperature to check, whether we have an overflow to the red channel. It's obscure, why your upper byte (green channel) has such high values from min=252 to max=253 by an image range from 13☌ to 27☌. The image-3.png is your 16 bit radiometric grayscale image with a temperature range from min 64868 to max 65250.

Just for information purposes: before writing this post I've read pretty much all the posts and outstanding information form Tomas123 on a similar topic relating to Filr (both within this forum and also from exiftool - great appreciation goes to Phil Harvey - as well and ImageMagik) I also downloaded and tried with no luck Thermovision from Joe-c (impressive work as well): unfortunately I do not have a programming background so I'm not really able to 'port' FIlir related scripts into Optris. I would like to be able to generate radiometric-thermal gray-scale images (tiff or jpeg) in order to process them with CV/SfM software to obtain one single mosaiced orthophoto and a 3D model retainng individual pixel thermal data one of the things (among the many others) that's creating problems, I guess, is the tiff 2-page structure - I saved the tiff as 2 separate files, but then the thermal information is lost. txt for the same fiel extension limitations ofthis forum). I'm basically in the same situation as Tuffi: I have an Optris PI400 imager, and I need to radimetrically (temperature data) process several hundreds of images taken at roughly 1 s inerval, however I'm facing some stumbling blocks: the Optris imager can generate either radiometric tiff's (8-bit, two-page unrecognized MakerNotes as per exiftool) or text files (.csv - either temperature data or temperature profile): I'm attaching 3 samples of the same scene, with the 3 different Optris saving options (the original Test1.tiff was reanmed to Test1.jpg since this forum doas not allow to upload tiff's - the jpg has retained thw 2-page layout I do not know if anything else has changed from the native tiff the 2.
