OAK-1

OAK-1 isn’t a standard USB camera.  It’s a 4-trillion-operations-per-second AI powerhouse that performs your AI models on-board, so that your host is free to do whatever you need it to do.  

Its integrated 12 MegaPixel camera module communicates over an on-board 2.1 Gbps MIPI interface directly to the Myriad X, which ingests this data and performs neural inference on it, returning the results over USB.

Such a data path offloads the host processor from all of this work.  In the common use case of object detection from a 12MP image, this means your host is now dealing with a 24 Kbps stream of what the objects are and where they are in the image, instead of a 2.1 Gbps stream of video.  So an 87,500 reduction in data your host has to deal with.

And such a reduction means that even on relatively-slow hosts, one can use dozens of OAK-1 without burdening the host CPU.

As an example, below is an example of running MobileNet-SSD:

OAK-1 + Raspberry Pi: 50+FPS, 0% RPi CPU Utilization

NCS2 + Raspberry Pi: 8FPS, 225% CPU Utilization

Features:

• 4 TOPS of processing power (1.4 TOPS for AI)

• Run any AI model, even custom architectured/built ones

• Encoding: H.264, H.265, MJPEG - 4K/30FPS, 1080P/60FPS

• Computer vision: warp/dewarp, resize, crop, edge detection, feature tracking

• Dimension: 97x29.5x22.9 mm

• Weight: 91g

Camera Specifications:

Available in two variants:

Both the Fixed-Focus and Auto-Focus variants have fixed-focus grayscale stereo cameras. The Auto-Focus vs. Fixed-Focus variants of OAK-D-Lite differ only in the 12.3 MP color camera. Fixed-Focus has the lens fixed in place mechanically and cannot move, whereas Auto-Focus has an electromagnet that controls the lens position dynamically.

• Auto-Focus can focus on objects dynamically, which is mainly useful for objects within 50cm of the device
• Fixed-Focus is recommended for heavy-vibration applications (e.g., drones, lawnmowers, bikes w/out suspension, etc. (see video)

Both Auto-Focus and Fixed-Focus can clearly see objects beyond 50 cm, working between 50 cm and infinity. Auto-Focus has the advantage that it can focus on objects as close as 10cm (see video).
