RVC2 inside

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

4 TOPS of processing power (1.4 TOPS for AI) - RVC2 NN Performance

Run any AI model, even custom-architectured/built ones - models need to be converted.

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

Computer vision: warp/dewarp, resize, crop via ImageManip node, edge detection, feature tracking. You can also run custom CV functions

Stereo depth perception with filtering, post-processing, RGB-depth alignment, and high configurability

Object tracking: 2D and 3D tracking with ObjectTracker node

On-device programming: Run custom logic/tasks on-device (guide)

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.

Ideal range: 30cm - 1m
MinZ 20cm (800P)

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

IR Dot Projector

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.

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.

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() 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

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.

Connectors

M8 aux connector has 8pin female A-coded connector and the M12 ethernet has 8pin female X-coded connector. Cameras also include an M8 connector cap for waterproofing in case the M8 connector wouldn't be used.

Pin	M12 pin	M8 pin	M8 functionality
1	Eth MX0+	BOOT	Pull this pin high with 10k resistor at startup for USB boot.
2	Eth MX0-	FSYNC ISO	Isolated Frame synchronization input signal for cameras
3	Eth MX1+	USB D+	USB 2.0 interface that can be used to connect to the OAK device (eg. reflash) if USB boot is enabled (via AUX GPIO 3V3).
4	Eth MX1-	USB D-	USB 2.0 interface that can be used to connect to the OAK device (eg. reflash) if USB boot is enabled (via AUX GPIO 3V3).
5	Eth MX3+	VBUSIN	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	Eth MX3-	Strobe ISO	Isolated Strobe output signal for cameras
7	Eth MX2+	GPIO 5V	GPIO 5V control signal
8	Eth MX2-	GND	Ground

External triggering: Sensors require 1V8 rising edge on FSYNC for the trigger event. The input trigger voltage should be 5V (goes through a level shifter to 1V8). For an example, see External FSYNC Example.

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 Operating Temperature documentation.
