Display the temperature from the thermal camera

[tamer_oz]

Hi everyone,

I am trying to make a program with Labview that will display the temperature value from the image of a thermal imaging camera (Flir E8).
The program already displays the thermal image, but when I click the mouse on the image, the temperature value is not displayed correctly at all. Can anyone help me to find the cause of this problem?
The vi file is attached. 

Thanks in advance

Please do share the LabVIEW Code in Lower Versions (LV 2017) not all the users are using latest ( At least my office system not been updated with Latest).

Can you be specific on the Problem with Camera Image/LabVIEW Application?

Hi Palanivel,

Sorry my bad. I added the 2015 Version. I also uploaded the screen shot. In the Labview program i can see the image and also the mouse position. But the temperature value in this position or any other position in the frame doesn't fit at all.

Judging by this:

There is something wrong with your format string

You have the Format String connected to the "Initial String" input not the "Format String" input of the Format Into String VI.

This:

 

Should be this:

Hi,
thanks for the hint. 

This is how it looks like now.

It looks like it is just a standard color image, are you sure you can extract temperature data from the pixel values?

I was thinking the same thing, I don't see how the image colors are being mapped to a temperature.

Plus there are missing sub-vi's so I could not really figure it out beyond the first error I spotted.

I think the missing VIs for you are from the Vision toolkit, I can see everything ok

Hi,
I was not sure about extracting the temperature from the pixel value. Now I have changed the block with ImagetoArray. The temperature value is not as high as last time, but it still doesn't fit. The temperature change can also be seen in the chart when I hold my hand in front of the camera. Screenshots for FrontPanel and BlockDiagram are attached in addition to the vi file.

Here is a color to temperature "map"

But I know what your saying 😉
