How the relay works
When Vision Engine runs on a remote VPS,
it cannot reach your phone's local IP (10.x.x.x).
relay.py runs on your laptop. It fetches frames from the phone and pushes them to the VPS over HTTPS — outbound only, no firewall rules needed.
The VPS stores the latest frame. Snapshot, stream, board‑view, calibration, and move detection all use it transparently.
If the phone IP changes, update the camera URL in the dashboard and relay.py auto-picks up the new URL within 30 seconds.

🔬 Detection Pipeline
① Ref Frame
before move (capture-ref)
② Cur Frame
after move (process-move)
③ Diff Raw
absdiff + blur + contrast ×1.3
④ Diff Threshold
binary threshold (MOVE_THRESHOLD)
⑤ Morphology Mask
dilate×4 + erode×2 + open + close
⑥ Contour Image
contours + chosen square labels
⑦ Highlight Frame
green=from, red=to (legal moves only)
⑧ Board View (post-move)
