Overview

The OAK-D Pro PoE is an upgraded version of OAK-D-PoE, featuring IR laser dot projector (active stereo) and IR illumination LED (for “night vision”). It’s also smaller and lighter than the OAK-D-PoE.

It also has industrial M12 PoE connector (instead of RJ45) and additionally features M8 connector for IO connectivity; USB2 (D+, D-), camera IOs (FSIN, STROBE), power, and 2 other auxiliary IOs, capable of UART, I2C or GPIO.

It’s currenty in beta stage so you have to use a custom version of the depthai library to communicate with this device, more information below at Getting started.

Hardware specifications

This OAK camera uses Power-over-Ethernet (PoE) for communication and power. It offers full 802.3af, Class 3 PoE compliance with 1000BASE-T speeds (1 Gbps) and has a micro SD (uSD) card connector. A PoE injector/switch is required to power the device.

How it works

This OAK model doesn’t have an IR filter on mono cameras (the production version will have notch IR filters at 940nm), which allows only visible light and IR light from illumination LED/laser dot projector to the camera.

Laser dot projector projects many small dots in front of the device, which helps with disparity matching, especially for low-visual-interest surfaces (blank surfaces with little to no texture), such as a wall or floor. The technique that we use is called ASV - conventional active stereo vision - as stereo matching is performed on the device the same way as on OAK-D (passive stereo).

On the image below there’s a blank wall with no texture. Without the dot projector, (passive) depth perception is poor. With dot projector set to ~200mA the (active) depth perception looks much better. If you look closely at the bottom left frame, you can see little dots all around the wall.

Blanket IR LED illumination allows perceiving low-light and no-light environments. You can run your AI/CV processes on frames that are illuminated by the IR LED. Note that the color camera doesn’t perceive IR light, so you would need to use a mono camera stream for your AI/CV processes.

Getting started

To get started with this OAK model, you first need to install depthai library version 2.15 or above. You can set IR laser dot projector and illumination LED via the API as below.

with dai.Device(pipeline) as device:
  device.setIrLaserDotProjectorBrightness(100) # in mA, 0..1200
  device.setIrFloodLightBrightness(0) # in mA, 0..1500

You can set these two parameters in DepthAI Demo in the Depth tab:

FOI = Field of illumination. Also note that in datasheet, HFOI and VFOI are switched, that’s because we mount the Belago1.1 rotated as we want greater horizontal field, to match field of cameras.

2

FSYNC

Frame synchronization signal for cameras. This pin can be configured as an input or an output.

3

USB+

USB 2.0 interface used as a host to control external devices. Could be used to connect to the device (eg. reflash), if USB boot is enabled (via GPIO 0).

4

This pin is used for sourcing 5V power to accessory devices connected to the M8 connector. If trying to boot the device in USB boot mode, this pin can also sink current.

6

GPIO 1

General purpose input output pin. This pin also supports UART_TX or I2C_SDA functionality.

7

GPIO 2

General purpose input output pin. This pin also supports UART_RX or I2C_SCL functionality.

8

Depth perception

This OAK camera has a baseline of 7.5cm - the distance between left and right stereo camera. Minimal and maximal depth perception depends on camera FOV, resolution, and baseline - more information here.

  • Min perceivable distance: ~20cm (400P, extended), ~35cm (400P OR 800P, extended), ~70cm (800P)

  • Max perceivable distance: ~35 meters

Extended means that StereoDepth node has Extended disparity mode enabled, more information here. Maximum perceivable distance calculation here.
