I have saved many IR thermal images at different instances of time in a folder using FLIR Quick plot software. Now, I want temperature value in each pixel for every images. How can i do that?
You can use FLIR Tools software where you can open the IR images captured by your camera. Then you can export the image as csv file which stores all the temperature values per pixel of your image.
If your camera is calibrated, you have an acces to the radiance temperature of each pixel in digital level (DL) using the export tool as a csv file. Then, this matrix can be imported in any data analysis software.
Be careful that:
1/ the response of the camera is a function of the selected integration time (see the CNUC manager file),
2/ the measured temperature does not consider the emissivity of the observed surface.
Thanks, Priya saha and Gossé Stéphane for your answers.
I used ThermaCam Researcher (30 days trial version) for finding the temperature in each pixel of IR image. This software allows saving the temperature data of each pixel in .mat and .csv format.
Keep in mind that the actual extracted value may not be very accurate, so that you would want to acquire images for a calibration standard (such as ice water, boiling water, blocks of metal at a known temperature, etc). I have found the Seek Thermal to be a better camera in terms of temperature accuracy (although the focal length is longer and makes it a bit unwieldy for handheld use - no problem for lab use if you have a mount and enough space).
I am also using seek thermal camera. But very new in this. Used this camera on android and took images which was saved in .jpg format. But I want to extract floating point temperature from that image.
For pc is there any software or SDK to get these value and store it in .csv or .mat or any other format for further analysis.
My questions were similar to above. Since FLIR has abandoned FLIR tools I think this will be a common problem
My solution to obtain metadata and process thermal images is to use exiftools with R. For a FLIR One Pro, this worked for me on a Mac and I'd expect Windows to be similar. Install exiftools, then run the script below in R. Refer to the Thermimage package help for e.g. aligning the legend and image. My key objectives were to be able to process the image, obtain metadata, and to be able to re-associate a functional legend with the image. The FLIR camera software does some other magic in linking the IR and visual image to sharpen it, and I haven't always been able to select a palette that's as good as the one on the camera, particularly when there's e.g. a very hot spot where most of the image is relative cold (details in the 'cold' zone are hard to see). I'm disappointed that FLIR has abandoned the Mac/Unix universe - a good reason to look elsewhere for some of us.
