This might be interest to some of you (even if it does use the "lowly" FLIR Lepton 3.5
). For the past couple of years I've been designing a wireless thermal imaging camera using the ESP32 and Lepton 3.5. My goal was to be able to make radiometric data available to people. The camera is designed so that various applications, including custom ones written by users, can connect to it via a socket interface over WiFi and use the data for a variety of purposes. In that sense it is a little different than the traditional thermal imaging camera. However I wrote a companion desktop application (running on Linux, OS X and Win), and an iOS app for iPhone/iPad (hope to have an android app later this year), as well as a python driver. The apps allow visualization and temperature plotting (desktop app). Other people have written Matlab and R drivers for getting the data into those environments.
The original design could be built using an ESP32 dev board and Lepton breakout from Group Gets. I also designed a PCB version and partnered with Group Gets to get it built. They have just finished the first run of the new revision 4 PCB and it's available on their website as two models (links below). Full disclosure: I do make a small commission on their sales but I'm not going get rich off this. Mostly I just wanted an easy way to share my work and they're a distributor for the Lepton so it was a good fit.
