ADOS Thermal Camera FLIR Lepton USB UVC

FLIR Lepton 3.5 radiometric thermal imaging via PureThermal 2 USB UVC dongle. Adds video overlay, FC config tab, and a MAVLink camera component.

Overview

Drives a FLIR Lepton 3.5 over a PureThermal 2 USB UVC dongle. The plugin opens the device, colorizes the radiometric Y16 feed with a selectable palette, and exposes controls for high and low gain and a one-touch flat field correction. Cockpit Skills cycle the palette and trigger an FFC; the same palette and gain render on the video overlay, which reads a live spot temperature under the reticle. When a colorized stream endpoint is available the thermal feed is offered to the video pipeline as its own selectable stream leg.

What it does

  • Radiometric Y16 thermal imaging with selectable colour palettes
  • High / low gain (temperature sensitivity vs range)
  • One-touch flat field correction
  • Cockpit Skills to cycle the palette and run an FFC
  • Video overlay with a live spot temperature

Skills

Version history

v1.2.0

LatestJul 19, 2026

Binds to a named thermal camera through the shared camera roster instead of registering its own driver. Spot-temperature telemetry and the colorized display stream ride separate channels so the video overlay stays truthful. Skills carry glyphs.
