Overview

The OAK-D Pro is an upgraded version of OAK-D, featuring an IR laser dot projector (active stereo) and IR illumination LED (for night-vision). OAK-D Pro is from the Series 2 of OAK cameras. It’s smaller and lighter than the OAK-D.

Compared to the OAK-D S2, the only difference is the dot projector/illumination LED (Pro aspect of the version). Otherwise, the PCB and enclosure are the same.

Due to the large power consumption of dot projector/illumination LED, a Y-adapter is required when using these functions!

How it works

This OAK model has notch IR filters at 940nm on the stereo camera pair, which allows both visible light and IR light from illumination LED/laser dot projector to be perceived by 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.

Night vision mode (right)

Getting started

You can set IR laser dot projector and illumination LED via the API as below. Note that the dot projector will be strongest at 765mA, as above that, the duty cycle will decrease.

# Either within Script node:
script = pipeline.create(dai.node.Script)
script.setScript("""
  Device.setIrLaserDotProjectorBrightness(500)
  Device.setIrFloodLightBrightness(0)
""")

with dai.Device(pipeline) as device:
  # Or, using the dai.Device object from the host:
  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:

Dimensions and Weight

Weight: 91g

Stereo depth perception

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

  • Ideal depth range: 70cm - 12m

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

  • Median depth accuracy (See 800P, 75mm baseline distance OAKs for details):

    • below 4m: below 2% absolute depth error

    • 4m - 7m: below 4% absolute depth error

    • 7m - 10m: below 6% absolute depth error

Integrated IMU

This OAK camera has an integrated BNO085, a 9-axis IMU (Inertial Measurement Unit). See IMU node for the API details on how to use it.

Note: due to supply chain issues, most of the OAK camera that were manufactured between Q2 2021 and Q2 2023 have integrated BMI270 - 6-axis IMU instead.

Power consumption

Most of the power is consumed by the RVC2, so the power consumption mostly depends on the workload of the VPU:

  • Base consumption + PoE circuitry + camera streaming: 3W - 3.5W

  • AI subsystem consumption: Up to 1W

  • Stereo depth pipeline subsystem: Up to 0.5W

  • Video Encoder subsystem: Up to 0.5W

Separately, OAK Pro cameras have illumination LED and laser dot projector, which are power configurable (more power - more brightness):

  • Dot projector (active stereo): Up to 1W

  • Illumination LED (night vision): Up to 1W

So the total power consumption can be up to ~7.5W if you are using all the features at 100% at the same time. To reduce the power consumption, you can reduce FPS of the whole pipeline - that way, subsystems won’t be utilized at 100% and will consume less power. You can also decrease power (and brightness) of the illumination LED and dot projector to reduce the overall power consumption of the device.

Operating temperature

The ambient operating temperature of RVC2 based devices is between -20°C and 50°C when fully utilizing the VPU.

Similarly to the Power consumption, max operating temperature depends on VPU utilization. The higher the VPU utilization, the more heat the VPU will generate. The RVC2 VPU can continuously operate at 105 °C, after which the depthai library will automatically shut down the device (to avoid chip damage).

To find out more, see our Operative temperature range documentation.

Vibration Testing

This OAK device has been tested for vibration tolerance according to the EN 60068-2-6:2008 standard:

  • Vibration Report - Report of the vibration stress tests performed by the SIQ (3rd-party lab)

  • Vibration Results - Results of Camera Focus, Camera Angles, and Stereo Depth Accuracy before and after the vibration stress tests

More information can be found at Vibration Tolerance documentation.
