Fluke .IS2 file reader

Simple function for reading out data from Fluke Thermal Imager -IS2 files.

Description

Ignores metadata, and assumes image data is on fixed offsets
Only tested on files from Ti10 instrument. Probably needs some modification to work on other instruments.
Anyone is very welcome to improve this function by interpreting the content of the meta-data fields .

Hi,
How is the file structure of Ti32 or Ti55?
thanks

Hi,

I need to load IS2 file from a TI32 instrument... your script is not exactly adapted to it but it was an essential start for understanding Fluke file format. So many thanks for that!

FYI, the visible image is not a grayscale but a RGB coding in 5:6:5 bits. So to get a color image from your 16-bit matrix vis, you just have to type:
v = zeros([480,640,3],'uint8');
v(:,:,3) = bitshift(bitand(vis,31),4); % 5 less significant bits = blue
v(:,:,2) = bitshift(bitand(bitshift(vis,-5),63),3); % 6 middle bits = green
v(:,:,1) = bitshift(bitshift(vis,-11),4); % 5 most significant bits = red
imagesc(v)

I will continue this work and probably submit a script adapted to TI32 files in the next days. As you I will try to get some of the metadata (I only need date, time and emissivity value).

If you think it may be of any interest, I may adapt the script to read TI10 files also...

Regards,

François.

thanks a lot! was just what i was looking for! now just need to work with the data i get!
