TIMI Changelog

2026-04-27

Dataset Viewer & Agent Workflow — Added Rerun-based dataset_viewer.py for browsing local and remote capture datasets with multi-mount support, sidecar normalization, timeline plots, and a web viewer on port 9090. Updated agent instructions for tmux window management (runio, tdash, gopro).
GoPro Client Inline Merge — Merged clients/gopro-scicam/ from submodule into the main repository as inline history, simplifying builds and removing submodule sync friction.
Tooling Suite — Added tools/colmap_parser and tools/mirror_server alongside the dataset viewer.

Unified Sidecar Schema v1.5 — All capture sources (Android and GoPro) now emit the same JSON sidecar format. Renamed item_id to qr_item_id, added device_name, device_id, and camera_file fields. Legacy v1 sidecars are preserved as-is.
Discovery Protocol Extracted — Moved UDP multicast beacon specification from AGENTS.md into references/discovery_protocol.md as a standalone reference document.
Box QR Workflow — Fullscreen borderless QR view on DP-1 for the GoPro client, per-capture UUID generation (capture_id), and gamepad “Next Box” button (Y) for rapid box cycling.
Dashboard Enhancements — Gallery and sidecar preview, capture_alert feedback, and beacon-based auto-discovery sync.

GoPro Station Mode — Split-screen full-screen view: live preview alongside the last capture. Accessible via UI button or F key.
QR Debounce & History — Require two consecutive QR detections before accepting a new code to reduce flicker. Added /api/qr_history endpoint and prominent QR info panel.
Real Camera Settings in Sidecars — GoPro bridge now queries actual ISO, shutter speed, aperture, focal length, and AE/AWB lock state from the camera for accurate metadata.
Lens Mode Toggle — Switch between Wide and Linear lens modes via API and UI; persists in sidecar JSON.
GoPro Deletion Fixes — Corrected delete path format (removed erroneous DCIM/ prefix), added bulk delete fallback, and robust Clear All flow.
Background Sync & Duplicate Prevention — Sync history tracks GoPro files across restarts so clearing local files does not trigger re-downloads.
XInput / Gamepad API Support — Xbox 360 controller mapped: A/X capture photo, Y advances box ID, B toggles QR overlay.
GoPro Auto-Capture v2 — Structural change detection with motion threshold and settle-delay parameters; captures only when objects remain on the table (ignores passing hands).
UI Polish — Event log panel, QR flash overlay on detection, ROI visibility toggle, modal robustness, and JSON sidecar panel in gallery.

SciCam API-First Rewrite — Fullscreen preview with IP overlay, NanoHTTPD REST API, removal of ZXing GUI hop.
QR Auto-Capture — BoofCV runs on preview frames; snaps automatically when a QR code is detected. Includes debug overlay, chime, and flash feedback.
Client Submodules — Added clients/go-scicam and clients/web-scicam as submodules.
OpenAPI 3.0 Spec — Formal API specification in api_spec.yaml.
Docker Build Support — Cached Docker builds for the Android app with restored Gradle wrapper.

SciCam v1.2.0 (2026-04-25) — UDP multicast auto-discovery, cached Docker builds.
SciCam v1.1.0 (2026-04-25) — Video recording (POST /record), /captures listing, /sidecar downloads, initial Rust dashboard.
SciCam v1.0.0 (2026-04-24) — Initial release with CameraX + BoofCV QR integration, photo capture, and JSON sidecars.
