Hey everyone, new to the forum. I am a ME/AE at the University of Florida doing a project on building a UAV for wildfire surveillance.We need an infrared camera and the only options that I have found so far is the Flir Tau series. The max resolution for the Flir Tau is 320x240. We are looking for a camera with a resolution of 640x480. The only camera from Flir is the Photon 640, which is about 2.5 times the weight, and 8x the volume.I was wondering if anyone knows of any other IR cameras with similar weight and volume similar to the Flir Tau? (~100 grams, 1.2"x1.2"x1.4")Thanks all. Great forum BTW, very helpful for my project.
You need to be a member of diydrones to add comments!
Just became aware of this company who invited me to a sales meeting last week. IRCameras Their Tamarisk line accepts various focal length lenses, on par with the Tau in terms of resolution and performance.
If anyone is interested, I managed to get the SEEK THERMAL camera to stream via WiFi using a Raspberry Pi 2. I'm next going to try to see if I can connect an analog video transmitter to it for IR FPV. (The Pi has an AV out on it).
This would be the only sub $500 solution for IR FPV that I have seen. On the Pi it can also record to an SD card.
We're still tinkering with the camera and Raspberry Pi but have not flown it yet. I can post some video soon. The image quality isn't great at ranges of more than 200', but it is readable. I am working with the Seek Thermal camera right now, but will be trying the Seek Thermal XR soon, which has a lens better suited to the job.
It will not produce anywhere near the image quality that the Tau camera offer's, but the whole system is less than 1/8 th the price.
We can offer thermal camera with resolution 640x512. That solution is favorites on universities because it is the only solution that offer radiometric data recording for subsequent processing.
If you're looking to detect Infrared radiation with wavelengths between 8-13 μm, you want a microbolometer. Don't let others confuse you with the claims that a standard CCD or CMOS array can be converted (by removing the IR filter) into acting like one... because it can't. The best standard CCD arrays can do is NIR (near infrared), which is a whole other wavelength. For true thermal imaging, you'll want a FLIR or equivalent (with a microbolometer sensor element). I'm looking at the PathFindIR (for the same application as you), but that's 320x240.

@Gary - This video contains some sample Thermal Images from the SEEK Camera.

I'm scaling the 204x156 image up to 640x480

I have been using the TAU 2 324 to track wildlife. I find it more than capable to do the the job. Here are some of the videos if interested in seeing it in action. https://www.youtube.com/playlist?list=PLfOneiFSbHfVnId8G_JJiHWvb7eZP...

- its 640 x 480 and seems to tick all the boxes.
Dont dismiss it because its Chinese - its used by at least 2 UK UAV manufacturers
