Hi to all,
First of all thanks a lot for helping me in this post.
I would like to connect optris thermal camera PI450i with labview.
What i would like to know is if I can create a ROI and then get the temperature in each pixel of this ROI.
Do anyone have experience in this?
I can do it with IMAQdx? (I dont know if there is a VI to get temperature measurement).
There is as well an Optris API for Labview but I dont know what features it has.
Thanks a lot!

Looking at the manual for the software (which looks like it is using LabVIEW) I would say that you should be able to do what you are looking to do. Look at the manual. It talks about everything that you are going to need to do. After you get the images you will need to find the pixels and look a the color. Then you are going to have to calibrate the color to a temperature.
My guess is you are going to need vision or IMAQ to do what you are hoping to do.
Here is a link to the software:
https://www.optris.com/downloads-software
It was right on their website. There is also a lot more info. I would start there. If you are new to LabVIEW this would be a very ambitious first project.

Thanks a lot for replying!
So I have different questions here:
- should I use SDK optris for Labview to do this?
- should I use just imaqdx to do this?
- should I use SDK optris + imaqdx to do this?
If I use imaqdx, can I have the temperature just with the colour of the pixel? Is this accurate?
Oh, I am not new (but I have to learn a lot a lot!!) My problem with this is the camera connection into labview and getting temperature pixels.
Where do you see that "manual for the software is using LabView")? I am cheking manual compact connect software, am I right?
Thanks a lot to everyone!

IMAQdx will be required for both. It is a driver set (tool set). If you want to do the code development yourself then you would have to learn LabVIEW and Vision.
For me I would look at the code that was provided and see if it is useful or if it would take more time to make it useful. A lot of times they use interns to do this type of code. Some companies provide good code but they make you pary for it if they put a lot of time into it. You will have to make that evaluation.

Thanks a lot friend, really usefull!
Yes, I know imaqdx I work with it but not usually with thermal cameras.
So If I can get temperature measurements accurate just from image (with some conversion between colour and temperature) it would be "easy" to implement.
Can I do that? Get temperature information just with value colour pixel?
Thanks a lot!

Yes you can do that. You will need to be able to look at the color and build a table or matrix to be able to equate a color to a temperature. It would be like calibrating voltage to temperature, just a bit more complicated and you have to do it for every pixel in the image. That could take some time depending on how big the pictures are.

Thanks a lot
I think you have taken away the question from my mind of whether I could do what I wanted or not with this camera and with labview.
And as you mentioned I think I can (imaqdx, API... whatever...)
Just another question (thanks a lot).
In this documentation API optris for Labview: link
I can see that Pi400i and PI450i is "coming soon". I would like to use PI450i, you think I can?
If this API is not compatible yet with Pi450i, I could continue using imaqdx without problem, right?
Thanks a lot!

It looks like to me they plan to make the camera compatible. It should be easy.They should just get an image and run it through the code that has the calibration info. The calibration should not change for the image unless the colors are slightly different. I would make the code work for any size picture so it is future safe (if I were writing this code).
The temperature code should not care what camera you are using if you did it right. You might need a correction factor if the camera colors are slightly different from each other based on the CMOS sensor.

Thanks friend,
So my first step will be using imaqdx only without API.
I think it could work.

Good luck. Stop back in if you have questions.
