Thanks for your interest in the Intel Edison Platform.
If you want to establish communication, you will need a driver in Linux (which I didn't find). Also this driver should be compatible with the Yocto Image of the Edison. If you want to create one, you will need knowledge of the hardware within the thermal camera. For this I would recommend to contact the Company in charge of the design of this device.
I have found this link (https://github.com/groupgets/LeptonModule/tree/master/software/edison_capture LeptonModule/software/edison_capture at master · groupgets/LeptonModule · GitHub ) were there is a sample code for the Flir Lepton camera, I haven't test, but maybe it can be useful for you.
