get the average temperature over an area

[francispau]

hello, 

I use the following example and I would rather read the temperature of a point, get the average temperature over an area, it seems that "property node" does not have this feature

I try to use color spectrum, but the graph does not draw the same colors as the photo IR_0045

I really don't know what to do,

do you have a idear

thank you

Do you have Vision Development Module installed or just Vision Acquisition Software? It's hard to do any image analysis/manipulation without the VDM.

i have Vision Development Module installed ( 8.5)  and labview 8.6

Thank you very much for your help

Have a look at the attached example. It computes the average RGB color over an arbitrary area, which you can specify by the ROI tools on the left side of the image control. Computation of the temperature based on the RGB value is up to you.

OK I've taken it as an entertaining excercise and did the conversion from RGB to temperature for you. I extracted the IR color palette from your image and for each color, I am searching for the closest matching color int the color palette. This is certainly not the fastest way how to do the conversion, but perhaps the most simple one.

incredible, nice example,  thank you very very very much
