RVC2 inside

This OAK device is built on top of the RVC2 architecture, with main features being:

Stereo depth perception

This OAK camera has a baseline of 20mm - the distance between the left and the right stereo camera. Minimal and maximal depth perception (MinZ and MaxZ) depends on camera FOV, resolution, and baseline - more information here.

IR perception

The Pro version of this device 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.
IR Dot Projector
IR Illumination LED
The IR 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 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.

Getting started

You can set IR laser dot projector and illumination LED via the API as below:
Python
1# Either within Script node:
2script = pipeline.create(dai.node.Script)
3script.setScript("""
4  Device.setIrLaserDotProjectorIntensity(0.5)
5  Device.setIrFloodLightIntensity(0)
6""")
7
8with dai.Device(pipeline) as device:
9  # Or, using the dai.Device object from the host:
10  device.setIrLaserDotProjectorIntensity(0.5) # in %, from 0 to 1
11  device.setIrFloodLightIntensity(0.0) # in %, from 0 to 1
You can set these two parameters in DepthAI Viewer in the Depth drop-down menu:

FOI = Field of illumination. Also note that in the 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.

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
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.

Illumination LED and laser dot projector

Power configurable (more power - more brightness):
  • Dot projector (active stereo): Up to 1W
  • Illumination LED (night vision): Up to 1W

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, the 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 documentation.
