megaAI (OAK-1) 4K USB3 AI Camera¶
Use OAK-1/megaAI on your existing host. Since the AI/vision processing is done on the Myriad X, a typical desktop could handle tens of OAK-1/megaAI plugged in (the effective limit is how many USB ports the host can handle).
And since it can encode 1080p and 4K video (see here) you can now even save 4K video on a Pi Zero!
Requirements¶
USB3C cable
USB2 or USB3 port on the host
What’s in the box?¶
megaAI / OAK-1
USB3C cable (3 ft.)
Getting Started Card
Setup¶
Install the Python API.
Verify installation¶
We’ll execute a DepthAI example Python script to ensure your setup is configured correctly. Follow these steps to test DepthAI:
Start a terminal session.
Clone the depthai example repository.
git clone https://github.com/luxonis/depthai.git
Access your local copy of depthai.
cd [depthai repo]
Install the example repository requirements.
python -m pip install -r requirements.txt
Run demo script.
python3 depthai_demo.pyThe script launches a window, starts the cameras, and displays a video stream annotated with object localization metadata:
In the screenshot above, DepthAI identified a TV monitor (1.286 m from the camera) and a chair (3.711 m from the camera).
See the list of object labels in our pre-trained OpenVINO model tutorial.
