# OpenVINO Object Detection

Real-time object detection using Intel OpenVINO runtime. Runs inside Docker for cross-platform support. Supports Intel NCS2 USB stick, Intel integrated GPU, Intel Arc discrete GPU, and any x86_64 CPU.

## Requirements

- **Docker Desktop 4.35+** (all platforms)
- **Optional hardware**: Intel NCS2 USB, Intel iGPU, Intel Arc GPU
- Falls back to CPU if no accelerator present

## How It Works

```
┌─────────────────────────────────────────────────────┐
│ Host (Aegis-AI)                                     │
│   frame.jpg → /tmp/aegis_detection/                 │
│   stdin  ──→ ┌──────────────────────────────┐       │
│              │ Docker Container              │       │
│              │   detect.py                   │       │
│              │   ├─ loads OpenVINO IR model   │       │
│              │   ├─ reads frame from volume   │       │
│              │   └─ runs inference on device  │       │
│   stdout ←── │   → JSONL detections          │       │
│              └──────────────────────────────┘       │
│   USB ──→ /dev/bus/usb (NCS2)                       │
│   DRI ──→ /dev/dri (Intel GPU)                      │
└─────────────────────────────────────────────────────┘
```

1. Aegis writes camera frame JPEG to shared `/tmp/aegis_detection/` volume
2. Sends `frame` event via stdin JSONL to Docker container
3. `detect.py` reads frame, runs inference via OpenVINO
4. Returns `detections` event via stdout JSONL
5. Same protocol as `yolo-detection-2026` — Aegis sees no difference

## Platform Setup

### Linux
```bash
# Intel GPU and NCS2 auto-detected via /dev/dri and /dev/bus/usb
# Docker uses --device flags for direct device access
./deploy.sh
```

### macOS (Docker Desktop 4.35+)
```bash
# Docker Desktop USB/IP handles NCS2 passthrough
# CPU fallback always available
./deploy.sh
```

### Windows
```powershell
# Docker Desktop 4.35+ with USB/IP support
# Or WSL2 backend with usbipd-win for NCS2
.\deploy.bat
```

## Model

Ships without a pre-compiled model by default. On first run, `detect.py` will auto-download `yolo26n.pt` and export to OpenVINO IR format. To pre-export:

```bash
# Runs on any platform (unlike Edge TPU compilation)
python scripts/compile_model.py --model yolo26n --size 640 --precision FP16
```

## Supported Devices

| Device | Flag | Precision | ~Speed |
|--------|------|-----------|--------|
| Intel NCS2 | `MYRIAD` | FP16 | ~15ms |
| Intel iGPU | `GPU` | FP16/INT8 | ~8ms |
| Intel Arc | `GPU` | FP16/INT8 | ~4ms |
| Any CPU | `CPU` | FP32/INT8 | ~25ms |
| Auto | `AUTO` | Best | Auto |

## Protocol

Same JSONL as `yolo-detection-2026`:

### Skill → Aegis (stdout)
```jsonl
{"event": "ready", "model": "yolo26n_openvino", "device": "GPU", "format": "openvino_ir", "classes": 80}
{"event": "detections", "frame_id": 42, "camera_id": "front_door", "objects": [{"class": "person", "confidence": 0.85, "bbox": [100, 50, 300, 400]}]}
{"event": "perf_stats", "total_frames": 50, "timings_ms": {"inference": {"avg": 8.1, "p50": 7.9, "p95": 10.2}}}
```

### Bounding Box Format
`[x_min, y_min, x_max, y_max]` — pixel coordinates (xyxy).

## Installation

```bash
./deploy.sh
```

The deployer builds the Docker image locally, probes for OpenVINO devices, and sets the runtime command. No packages pulled from external registries beyond Docker base images and pip dependencies.
