All as previously described:
Pre-requisits for image processing software:
- imagemagick
- php
- splitjpg.php script
source:
https://www.eevblog.com/forum/testgear/flir-e4-thermal-imaging-camera-teardown/msg348715/#msg348715- a sample image from the same E4 camera
- FLIR Tools
workflow:
- capture a RAW video
- split to individual frames
split -b 153600 test1.raw
- convert the required frame (in this example the first frame) to a RAW png
convert -depth 16 -size 320x240 gray:xaa raw1.png
convert the RAW png to radiometric jpg (for a template use a sample jpg image, e.g. FLIR0123.jpg, from the same camera:
php splitjpg.php -i FLIR0123.jpg -r raw1.png -o test1.jpg
note: after this step the resulting test1.jpg preview will appear the same as the template image, do not worry: the actual RAW data is hidden behind the image.
Now load this JPG into FLIR Tools to rebuild the preview image, place temperature measurements, apply a desired palette and resave.
I do video capture, split and convert on a Ubuntu VM, everything else on a Windows 7.
