New src/thermalcam.py auto-detects InfiRay/Topdon USB thermal cameras and decodes real temperatures: TC001 (256x384, /64) and TC002C Duo (512x484, /16, which also yields a clean 512x384 image), with a labelled relative fallback otherwise. Adds docs/TC002C-DUO.md (frame layout + reverse-engineered vendor protocol), requirements.txt, and an experimental command module. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- src/thermal_bridge.py: serve the parsed/colormapped thermal image as an MJPEG-over-HTTP stream so any app (OpenCV, ffmpeg, browser) can consume it like a webcam, no dependency. - thermalcam: --rotate / --flip (live 'o' key) and a clean colormap_frame() method (overlay-free) used by the bridge.

These cameras occasionally emit a horizontally-tiled/desynced frame. The frame validity check only looked at the temperature band, so such frames slipped through as garbage. Add an image-band alignment guard (mean-abs-difference vs a shifted copy; gradients and flat scenes are exempt) so the viewer and the MJPEG bridge never emit them. The bridge also reopens the camera after a run of unusable frames to recover from a stuck desync. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

src/thermalcam.py, a camera-agnostic rewrite oftc001v4.2.pythat also works with newer InfiRay/Topdon models (tested on a TC002C Duo).--device).256x384(/64) and TC002C Duo512x484(/16, which also gives a clean 512×384 image). Relative fallback otherwise, clearly labelled.CAP_PROP_BUFFERSIZE=1(OpenCV returns desynced buffers),VIDIOC_ENUM_FRAMESIZES(opening an unsupported mode desyncs the stream), skip desynced frames, telemetry trim, fixed-pattern-noise removal.--selftest.docs/TC002C-DUO.mddocuments the frame layout and the reverse-engineered vendor command protocol;src/thermal_protocol.pyis an experimental (dry-run) module for optional NUC/calibration.The original
tc001v4.2.pyis left untouched.
