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

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.

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.

5Eth MX3+VBUSINThis 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.

7Eth MX2+Isolated GNDIsolated ground for Strobe/FSYNC
8Eth MX2-GNDGround
External triggering: Sensors require 1V8 rising edge on FSYNC for the trigger event. We are using an optocoupler and ESD protection diode, so the input trigger voltage should be 12V (up to 24V) and the trigger logic is reversed, so trigger event happens at 0V on the FSYNC line. For an example, see External FSYNC Example.

Laser Safety
