If you had a reference temperature for a certain color and knew how color scaled with temperature then you might be able to do the calculations in LabVIEW. It looks like that camera might provide temperature values through it's onboard display. You could use this to get a reference temperature. As for understanding the scaling, I recommend reaching out to the manufacturer.
Overall, there's likely no native solution in LabVIEW to relate color to temperature. You'll need to learn how the camera is mapping these and then calculate manually from there.
Additionally, how are you planning to acquire the images in LabVIEW? From what I see about this camera online, it looks like a handheld package without any bus to steam the images back to a computer. It seems like there is a USB 2.0 port for file transfer. However, this would only allow for transferring the images to the PC for post processing well after the acquisition. There wouldn't be any capabilities for continuously acquiring and processing the images in LabVIEW.
