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 one auxiliary GPIO.

Hardware specifications

This OAK camera uses Power-over-Ethernet (PoE) for communication and power. It offers full 802.3af and Class 3 PoE compliance with 1000BASE-T speeds (1 Gbps). A PoE injector/switch is required to power the device. It also features IP65 rated enclosure.

Sensor specifications

You can select either FF or AF color camera, more information here.

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).

Note

Laser dot projector and flood LED are disabled by default! That’s because most people would prefer intentionally enabling the laser dot projector when they are wearing eye safety gear.

On the image below there’s a blank wall with no texture. Without the dot projector, (passive) depth perception is poor. With the 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.

Flood 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.

Regarding operating temperature; some customers use dot projector even at lower ambient temperatures, but first wait a few minutes for device to heat up (by running AI/CV/stereo depth…) so projector gets to above 0°C.

RVC2 inside

This OAK device is built on top of the RVC2. Main features:

External triggering: Sensors require 1V8 rising edge on FSYNC for the trigger event. We are using optocoupler and ESD protection diode, so the input trigger voltage can be up to 24V and trigger logic is reversed, so trigger event happens at 0V on FSYNC line.

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.

  • MinZ: ~20cm (400P, extended), ~35cm (400P OR 800P, extended), ~70cm (800P)

  • Theoretical MaxZ, docs): ~35 meters

  • Practical MaxZ (real world): ~15 meters with a variance of 10% (depth accuracy evaluation)

Extended means that StereoDepth node has Extended disparity mode enabled.

Operational Temperature

This device is rated to withstand temperatures within the range of -33° C - 55° C. Use in temperatures outside of this range may result in device failure.
