Coral TPU Object Detection

Real-time object detection natively utilizing the Google Coral Edge TPU accelerator on your local hardware. Detects 80 COCO classes (person, car, dog, cat, etc.) with ~4ms inference on 320x320 input.

Requirements

• Python 3.9, 3.13

How It Works

┌─────────────────────────────────────────────────────┐
│ Host (Aegis-AI)                                     │

│              │   └─ runs inference on TPU    │       │
│   stdout ←── │   → JSONL detections          │       │

└─────────────────────────────────────────────────────┘

1. Aegis writes camera frame JPEG to shared /tmp/aegis_detection/ workspace
2. Sends frame event via stdin JSONL to the local Python instance
3. detect.py invokes PyCoral and executes natively on the mapped USB Edge TPU
4. Returns detections event via stdout JSONL

Platform Setup

Linux

# Uses the official apt-get google-coral packages natively
./deploy.sh

macOS

# Downloads and installs the libedgetpu OS payload framework inline
./deploy.sh

Important Deployment Notice: The updated deploy.sh script will natively halt execution and prompt you securely for your OS sudo password to securely register the USB drivers (libedgetpu) system-wide. If you refuse the prompt, it gracefully outputs the exact terminal instructions for you to configure it manually.
