amc-run-video-calibration

Calibrate a new dataset from pre-recorded video files via the AutoMagicCalib REST API. Use when user has local MP4s and says 'calibrate my videos', 'run AMC on these videos', or similar. For RTSP/live streams, use amc-run-rtsp-calibration instead.

Skill: Calibrate from Video Files

When to Use This Skill

Activate this skill when the user has pre-recorded MP4 files and wants to calibrate them via the AMC REST API. Typical prompts:

"calibrate my videos" / "run AMC on these videos"
"calibrate from video files"

Drives calibration through the REST API on user-supplied pre-recorded MP4 files — no CLI scripts or Docker bind-mounts required, just a running microservice and your files.

Do not use this skill for live RTSP streams or rtsp://... URLs; route those requests to skills/amc-run-rtsp-calibration/SKILL.md.

Prerequisites

AMC microservice and UI running (follow skills/amc-setup-calibration-stack/SKILL.md)
You know the microservice URL (e.g. http://<HOST_IP>:<MS_PORT>) and UI URL
Video files locally as cam_00.mp4, cam_01.mp4, … time-synchronized, ~1920×1080
Python 3 with requests

Data Privacy

Video files uploaded via this skill are transmitted to the AutoMagicCalib backend (REST endpoint). Only use this skill when the backend is deployed on a trusted platform / network.

What to Ask the User

Required

(Video-file naming and the microservice URL are specified under Prerequisites above — collect the inputs below.)

Videos directory — the folder the skill globs for cam_*.mp4, uploaded sorted alphabetically.
Microservice URL
Project name — short descriptive string

Auto-Detected (ask only if not found)

The script searches the videos dir, its first-level subdirectories, and its parent. If exactly one match is found, it is used; otherwise the script prints the searched locations and continues to explicit path or UI fallback:

File	Candidate filenames	UI fallback
Calibration settings	`settings.json`, `config.json`, `calibration_config.json`	UI Step 3: Parameters
Alignment JSON	`alignment_data.json`	UI Step 4: Alignment
Layout PNG	`layout.png`	UI Step 4: Alignment

Posting the settings file replaces UI Step 3 and may pin the detector (resnet/transformer), which is passed to /calibrate separately — see Step 4.

Optional

Ground truth zip — GT.zip with _World_Cameras_Camera_XX/ folders (enables evaluation metrics)
Focal lengths — one per camera, e.g. 1269.0, 1099.5, 1099.5
Detector type — resnet (default, fast) or transformer (slower, better under occlusion)
Run VGGT refinement? — if VGGT is ready after AMC completes, ask the user whether to run refinement (see setup skill)

See root README.md "Custom Dataset" section for input-video guidelines and ground-truth format.

Instructions

All endpoints below are implemented end-to-end in the Complete Python Script — the prose is the workflow plus the decisions the agent must make; the script is the authoritative runnable.

Step 1 — Create Project

POST /v1/create_project (form field project_name) → save the returned project_id.

Step 2 — Upload Videos (required)

POST /v1/upload_video_files/<project_id> (multipart files). Upload sorted alphabetically — the server assigns camera indices by upload order.

Step 3 — Resolve Local Files (Auto-Scan, Ask, or UI)

For each of calibration-settings, alignment, and layout, run this resolution:

Auto-scan VIDEO_DIR, one level of subdirectories under VIDEO_DIR, and VIDEO_DIR.parent for the candidate filenames (table above).
If exactly one match, use it and print what was found.
If zero or multiple matches, print the searched locations, then ask the user for an explicit path using the host's question mechanism; if none is available, ask in chat and wait. If they don't have the file, mark it for UI fallback.
UI fallback: tell the user to complete the corresponding UI step; wait for confirmation; for alignment/layout also verify files landed in projects/project_<id>/manual_adjustment/.

Step 4 — Upload Resolved Files

Upload each file resolved locally:

File	Endpoint	Notes
Calibration settings	`POST /v1/config/<project_id>` (JSON, posted as-is)	Replaces UI Step 3 (rectification, bundle-adjustment, evaluation, detector, …). Non-2xx is surfaced — never silently fall back. Skip on the UI-fallback path.
Alignment	`POST /v1/upload_alignment/<project_id>` (`alignment_data.json`)
Layout	`POST /v1/upload_layout/<project_id>` (`layout.png`)
Ground truth (optional)	`POST /v1/upload_gt_file/<project_id>` (`GT.zip`)	Enables evaluation metrics
Focal lengths (optional)	`POST /v1/upload_focal_length/<project_id>` (repeated `focal_length=`)	Overrides GeoCalib estimates

After a successful settings POST, parse the file for "detector" / "detector_type" — if it's "resnet" or "transformer", use that value for the /calibrate call in Step 7 (detector is a separate API parameter, not consumed by /config).

Step 5 — UI Fallback (only for files the user doesn't have locally)

If any of settings / alignment / layout was not resolved in Step 3, direct the user to the appropriate UI step:

Settings missing → "Open UI project <project_id>, go to Step 3: Parameters, tune via the settings dialog (or accept defaults), click Save." Also: before the /calibrate call, ask the user which detector to use (resnet or transformer) using the host's question mechanism; if none is available, ask in chat and wait. UI Step 3 does not cover detector choice.
Alignment or layout missing → "Open UI project <project_id>, go to Step 4: Alignment, upload layout, mark correspondence points, click Save."

Wait for user confirmation. For non-interactive script runs, provide the needed files up front; the script exits with a clear message rather than waiting on input. For alignment/layout, verify on disk before continuing:

: "${REPO_ROOT:?set REPO_ROOT to the auto-magic-calib checkout. Run amc-setup-calibration-stack Step 0b first.}"
grep -q "AutoMagicCalib" "$REPO_ROOT/README.md" 2>/dev/null && grep -q "auto-magic-calib-ms" "$REPO_ROOT/compose/ms/compose.yml" 2>/dev/null || { echo "ERROR: REPO_ROOT is not an auto-magic-calib checkout: $REPO_ROOT" >&2; exit 1; }
# Resolve PROJECT_DIR from the Compose environment file (default: projects/ at repo root).
COMPOSE_ENV_BASENAME="env"
COMPOSE_ENV_FILE="$REPO_ROOT/compose/.${COMPOSE_ENV_BASENAME}"
PROJECT_DIR_REL=$(grep ^PROJECT_DIR "$COMPOSE_ENV_FILE" 2>/dev/null | cut -d= -f2 | tr -d '[:space:]')
HOST_PROJECTS=$(cd "$REPO_ROOT/compose" && realpath "${PROJECT_DIR_REL:-../../projects}")

ls "$HOST_PROJECTS/project_<project_id>/manual_adjustment/"
# Expected: alignment_data.json, layout.png

Step 6 — Verify Project

POST /v1/verify_project/<project_id> → must return {"project_state": "READY"} before calibrating.

Step 7 — Start Calibration

Confirm the plan before calibrating. Whether the settings file and detector were auto-detected or asked, present a short summary and get explicit user confirmation before POST /calibrate using the host's question mechanism; if none is available, ask in chat and wait. The resolved values are the defaults, so confirming is one click, but the user can switch the detector or skip an auto-detected settings file. The standalone Python script prints the same plan and prompts only when stdin is interactive. Summarize:

Detector — resnet or transformer (the value to be sent).
Calibration settings — the file being applied (path), or "defaults" if none.
Optional overrides — ground-truth zip and focal lengths, if any.

POST /v1/calibrate/<project_id>
Content-Type: application/json

{"detector_type": "resnet"}

Step 8 — Poll for Completion

GET /v1/get_project_info/<project_id> every 10 s — project_info.project_state goes RUNNING → COMPLETED (or ERROR, pull the log). Typical time: 10–60 min depending on video length and detector.

Step 9 — Get Results

GET /v1/result/<project_id>/evaluation_statistics (only if GT was uploaded; includes Average L2 distance(m) and Average reprojection error 0(px)), and GET /v1/amc/calibrate/<project_id>/log for the calibration log.

Status Fields from `get_project_info`

project_info.project_state is the AMC calibration lifecycle for the project: RUNNING → COMPLETED (or ERROR).

project_info.vggt_state is also per-project, a project-scoped VGGT refinement lifecycle rather than a direct global service or model-load status. A newly created project can report vggt_state: "INIT" even when the VGGT model is present and mounted. The expected VGGT lifecycle is INIT → READY after AMC calibration completes → RUNNING while VGGT refinement runs → COMPLETED (or ERROR).

Use vggt_state == "READY" only as the gate for optional VGGT refinement in Step 10. Interpret INIT on a new or uncalibrated project as normal project state. If AMC calibration is complete and the project remains in a non-ready VGGT state, confirm VGGT setup and model availability with the setup skill checks and service logs.

After AMC calibration completes, read vggt_state from GET /v1/get_project_info/<project_id>.

If the project reports vggt_state == "READY", ask the user whether to run VGGT refinement using the host's question mechanism; if none is available, ask in chat and wait.
If the user confirms, POST /v1/vggt/calibrate/<project_id>, poll vggt_state via get_project_info, then GET /v1/vggt_results/<project_id>/evaluation_statistics.
If VGGT is not ready, skip refinement and explain that the user can set up VGGT with amc-setup-calibration-stack and rerun this optional step later.

The standalone Python script prompts only when stdin is interactive. In non-interactive runs, set RUN_VGGT = True to opt in; otherwise the script prints that VGGT is ready and continues without blocking.

Complete Python Script

Use the bundled script from the amc-run-video-calibration skill package, not from the auto-magic-calib repo root. If the user points the agent at this skill folder directly instead of installing it, set AMC_VIDEO_SKILL_DIR to the directory containing this SKILL.md, or run the command from that directory. Set BASE_URL, PROJECT_NAME, and VIDEO_DIR; optional env vars are CONFIG_FILE, ALIGNMENT_JSON, LAYOUT_PNG, GT_ZIP, FOCAL_LENGTHS, DETECTOR_TYPE, RUN_VGGT, REPO_ROOT, and PROJECTS_DIR. The script implements UI fallback, plan confirmation, VGGT prompt/opt-in behavior, polling, and refined statistics retrieval.

# Optional but recommended: REPO_ROOT points to the auto-magic-calib checkout.
# PROJECTS_DIR can be set explicitly when project outputs live elsewhere.

# Skill: Calibrate from Video Files

## When to Use This Skill

Activate this skill when the user has pre-recorded MP4 files and wants to calibrate them via the AMC REST API. Typical prompts:

- "calibrate my videos" / "run AMC on these videos"
- "calibrate from video files"

Drives calibration through the REST API on user-supplied **pre-recorded MP4 files** — no CLI scripts or Docker bind-mounts required, just a running microservice and your files.

Do not use this skill for live RTSP streams or `rtsp://...` URLs; route those requests to `skills/amc-run-rtsp-calibration/SKILL.md`.

## Prerequisites

- [ ] AMC microservice **and** UI running (follow `skills/amc-setup-calibration-stack/SKILL.md`)
- [ ] You know the microservice URL (e.g. `http://<HOST_IP>:<MS_PORT>`) and UI URL
- [ ] Video files locally as `cam_00.mp4`, `cam_01.mp4`, … time-synchronized, ~1920×1080
- [ ] Python 3 with `requests`

## Data Privacy

Video files uploaded via this skill are transmitted to the AutoMagicCalib backend (REST endpoint). Only use this skill when the backend is deployed on a trusted platform / network.

## What to Ask the User

### Required
(Video-file naming and the microservice URL are specified under Prerequisites above — collect the inputs below.)
1. **Videos directory** — the folder the skill globs for `cam_*.mp4`, uploaded sorted alphabetically.
2. **Microservice URL**
3. **Project name** — short descriptive string

### Auto-Detected (ask only if not found)

The script searches the videos dir, its first-level subdirectories, and its parent. If exactly one match is found, it is used; otherwise the script prints the searched locations and continues to explicit path or UI fallback:

| File | Candidate filenames | UI fallback |
|---|---|---|
| Calibration settings | `settings.json`, `config.json`, `calibration_config.json` | UI Step 3: Parameters |
| Alignment JSON | `alignment_data.json` | UI Step 4: Alignment |
| Layout PNG | `layout.png` | UI Step 4: Alignment |

Posting the settings file replaces UI Step 3 and may pin the detector (`resnet`/`transformer`), which is passed to `/calibrate` separately — see Step 4.

### Optional
4. **Ground truth zip** — `GT.zip` with `_World_Cameras_Camera_XX/` folders (enables evaluation metrics)
5. **Focal lengths** — one per camera, e.g. `1269.0, 1099.5, 1099.5`
6. **Detector type** — `resnet` (default, fast) or `transformer` (slower, better under occlusion)
7. **Run VGGT refinement?** — if VGGT is ready after AMC completes, ask the user whether to run refinement (see setup skill)

See root `README.md` "Custom Dataset" section for input-video guidelines and ground-truth format.

## Instructions

All endpoints below are implemented end-to-end in the [Complete Python Script](#complete-python-script) — the prose is the workflow plus the decisions the agent must make; the script is the authoritative runnable.

### Step 1 — Create Project

`POST /v1/create_project` (form field `project_name`) → save the returned `project_id`.

### Step 2 — Upload Videos (required)

`POST /v1/upload_video_files/<project_id>` (multipart `files`). **Upload sorted alphabetically** — the server assigns camera indices by upload order.

### Step 3 — Resolve Local Files (Auto-Scan, Ask, or UI)

For each of calibration-settings, alignment, and layout, run this resolution:

1. **Auto-scan** `VIDEO_DIR`, one level of subdirectories under `VIDEO_DIR`, and `VIDEO_DIR.parent` for the candidate filenames (table above).
2. If **exactly one match**, use it and print what was found.
3. If **zero or multiple matches**, print the searched locations, then ask the user for an explicit path using the host's question mechanism; if none is available, ask in chat and wait. If they don't have the file, mark it for UI fallback.
4. **UI fallback**: tell the user to complete the corresponding UI step; wait for confirmation; for alignment/layout also verify files landed in `projects/project_<id>/manual_adjustment/`.

### Step 4 — Upload Resolved Files

Upload each file resolved locally:

| File | Endpoint | Notes |
|---|---|---|
| Calibration settings | `POST /v1/config/<project_id>` (JSON, posted as-is) | Replaces UI Step 3 (rectification, bundle-adjustment, evaluation, detector, …). Non-2xx is surfaced — never silently fall back. Skip on the UI-fallback path. |
| Alignment | `POST /v1/upload_alignment/<project_id>` (`alignment_data.json`) | |
| Layout | `POST /v1/upload_layout/<project_id>` (`layout.png`) | |
| Ground truth (optional) | `POST /v1/upload_gt_file/<project_id>` (`GT.zip`) | Enables evaluation metrics |
| Focal lengths (optional) | `POST /v1/upload_focal_length/<project_id>` (repeated `focal_length=`) | Overrides GeoCalib estimates |

After a successful settings POST, parse the file for `"detector"` / `"detector_type"` — if it's `"resnet"` or `"transformer"`, use that value for the `/calibrate` call in Step 7 (detector is a separate API parameter, not consumed by `/config`).

### Step 5 — UI Fallback (only for files the user doesn't have locally)

If any of settings / alignment / layout was not resolved in Step 3, direct the user to the appropriate UI step:

- **Settings missing** → "Open UI project `<project_id>`, go to **Step 3: Parameters**, tune via the settings dialog (or accept defaults), click Save." **Also**: before the `/calibrate` call, ask the user which detector to use (`resnet` or `transformer`) using the host's question mechanism; if none is available, ask in chat and wait. UI Step 3 does not cover detector choice.
- **Alignment or layout missing** → "Open UI project `<project_id>`, go to **Step 4: Alignment**, upload layout, mark correspondence points, click Save."

Wait for user confirmation. For non-interactive script runs, provide the needed files up front; the script exits with a clear message rather than waiting on input. For alignment/layout, verify on disk before continuing:

```bash
: "${REPO_ROOT:?set REPO_ROOT to the auto-magic-calib checkout. Run amc-setup-calibration-stack Step 0b first.}"
grep -q "AutoMagicCalib" "$REPO_ROOT/README.md" 2>/dev/null && grep -q "auto-magic-calib-ms" "$REPO_ROOT/compose/ms/compose.yml" 2>/dev/null || { echo "ERROR: REPO_ROOT is not an auto-magic-calib checkout: $REPO_ROOT" >&2; exit 1; }
# Resolve PROJECT_DIR from the Compose environment file (default: projects/ at repo root).
COMPOSE_ENV_BASENAME="env"
COMPOSE_ENV_FILE="$REPO_ROOT/compose/.${COMPOSE_ENV_BASENAME}"
PROJECT_DIR_REL=$(grep ^PROJECT_DIR "$COMPOSE_ENV_FILE" 2>/dev/null | cut -d= -f2 | tr -d '[:space:]')
HOST_PROJECTS=$(cd "$REPO_ROOT/compose" && realpath "${PROJECT_DIR_REL:-../../projects}")

ls "$HOST_PROJECTS/project_<project_id>/manual_adjustment/"
# Expected: alignment_data.json, layout.png
```

### Step 6 — Verify Project

`POST /v1/verify_project/<project_id>` → must return `{"project_state": "READY"}` before calibrating.

### Step 7 — Start Calibration

**Confirm the plan before calibrating.** Whether the settings file and detector were auto-detected or asked, present a short summary and get explicit user confirmation before `POST /calibrate` using the host's question mechanism; if none is available, ask in chat and wait. The resolved values are the defaults, so confirming is one click, but the user can switch the detector or skip an auto-detected settings file. The standalone Python script prints the same plan and prompts only when stdin is interactive. Summarize:

- **Detector** — `resnet` or `transformer` (the value to be sent).
- **Calibration settings** — the file being applied (path), or "defaults" if none.
- **Optional overrides** — ground-truth zip and focal lengths, if any.

```
POST /v1/calibrate/<project_id>
Content-Type: application/json

{"detector_type": "resnet"}
```

### Step 8 — Poll for Completion

`GET /v1/get_project_info/<project_id>` every 10 s — `project_info.project_state` goes `RUNNING` → `COMPLETED` (or `ERROR`, pull the log). Typical time: **10–60 min** depending on video length and detector.

### Step 9 — Get Results

`GET /v1/result/<project_id>/evaluation_statistics` (only if GT was uploaded; includes `Average L2 distance(m)` and `Average reprojection error 0(px)`), and `GET /v1/amc/calibrate/<project_id>/log` for the calibration log.

### Status Fields from `get_project_info`

`project_info.project_state` is the AMC calibration lifecycle for the project: `RUNNING` → `COMPLETED` (or `ERROR`).

`project_info.vggt_state` is also **per-project**, a project-scoped VGGT refinement lifecycle rather than a direct global service or model-load status. A newly created project can report `vggt_state: "INIT"` even when the VGGT model is present and mounted. The expected VGGT lifecycle is `INIT` → `READY` after AMC calibration completes → `RUNNING` while VGGT refinement runs → `COMPLETED` (or `ERROR`).

Use `vggt_state == "READY"` only as the gate for optional VGGT refinement in Step 10. Interpret `INIT` on a new or uncalibrated project as normal project state. If AMC calibration is complete and the project remains in a non-ready VGGT state, confirm VGGT setup and model availability with the setup skill checks and service logs.

### Step 10 — (Optional) VGGT Refinement

After AMC calibration completes, read `vggt_state` from `GET /v1/get_project_info/<project_id>`.

- If the project reports `vggt_state == "READY"`, ask the user whether to run VGGT refinement using the host's question mechanism; if none is available, ask in chat and wait.
- If the user confirms, `POST /v1/vggt/calibrate/<project_id>`, poll `vggt_state` via `get_project_info`, then `GET /v1/vggt_results/<project_id>/evaluation_statistics`.
- If VGGT is not ready, skip refinement and explain that the user can set up VGGT with `amc-setup-calibration-stack` and rerun this optional step later.

The standalone Python script prompts only when stdin is interactive. In non-interactive runs, set `RUN_VGGT = True` to opt in; otherwise the script prints that VGGT is ready and continues without blocking.

If the user points the agent at this skill folder directly instead of installing it, set `AMC_VIDEO_SKILL_DIR` to the directory containing this `SKILL.md`, or run the command from that directory. Set `BASE_URL`, `PROJECT_NAME`, and `VIDEO_DIR`; optional env vars are `CONFIG_FILE`, `ALIGNMENT_JSON`, `LAYOUT_PNG`, `GT_ZIP`, `FOCAL_LENGTHS`, `DETECTOR_TYPE`, `RUN_VGGT`, `REPO_ROOT`, and `PROJECTS_DIR`. The script implements UI fallback, plan confirmation, VGGT prompt/opt-in behavior, polling, and refined statistics retrieval.
