With its 15cm baseline OAK-D LR is capable of precise depth readings up to ~30 m. And of course it offers all the features of OAK-D line, RVC2 core and the ability to run any AI model.

This camera is ideal for outdoor use, thanks to its IP65 certification for water and dust resistance.

Description

The OAK-D LR is a series 2 OAK camera offering 4 TOPS processing power and the ability to run any AI model. It was designed to provide an accurate short range and long range stereo depth perception. This works by having up to 3 stereo depth pairs at different baseline distances 5, 10 and 15cm. One can also easily change the M12 lenses for the cameras, which also affects the min/max distance of stereo depth perception and with very narrow FOV lenses it's possible to achieve 100m+ of stereo depth perception.

The OAK-D LR leverages our OAK-SoM-Pro to make a overall compact design. The use of the SoM reduces the design’s scale, making it easier to mount or fit in various robotic processes. The design is also allowing for any necessary .

Camera specifications

OAK-D-LR offers triple RGB global shutter camera with M12 lenses that are easily swappable.

Stereo Depth Perception

This OAK camera has a baseline of 5 cm, 10 cm, and 15 cm. Baseline distance is the distance between the left and the right stereo camera. Since we have 3 camera sensors on the OAK-D-LR, we also have 3 baseline distances, and 3 potential stereo pairs. We measured the accuracy of the 15 cm stereo pair (the left-most and right-most camera).

• 20cm - 6m: below 2% absolute depth error
• 6m - 8m: below 4% absolute depth error
• 8m - 12m: below 6% absolute depth error

As M12 lenses are swappable, user can easily change lenses to achieve wider FOV, or longer depth perception (narrower FOV):

Note:We haven’t tested all of these combinations, but calculated theoretical depth error and interpolated those values with our previous real-world tests when enabling subpixel disparity:

• < 2% error - 20th disparity pixel, which has 5% full-pixel error (~2% with subpixel enabled)
• < 4% error - 8th disparity pixel, which has 12.5% full-pixel error (~4% with subpixel enabled)
• < 8% error - 4th disparity pixel, which has 25% full-pixel error (~10% with subpixel enabled)

Maximum depth was calculated by using the large (15cm) baseline, while MinZ was calculated by using the small (5cm) baseline of the OAK-D-LR. You can further decrease MinZ by lowering the resolution, or using disparity shift ( docs here). MinZ values are already using Extended Disparity Mode.

As OAK-D-LR’s camera modules use M12 lenses, users can replace them without any special tools. By default, lenses are glued to the camera module, but users can remove the glue and replace the M12 lens with a different one. ArduCam’s M12 lens kit can be quite useful to test a variety of lenses to choose from.

There is 11.6mm of clearance between the M12 sensor housing and the cover lens. If you are using longer lenses (longer focal length which means narrower FOV), you might not be able to mount back the front cover.

Power and connectivity

For communication and power, the OAK-D LR camera uses either:

• USB-C - it supports both USB2 and USB3 (USB 3.1 Gen2, 5Gbps / 10Gbps).
• Power-over-Ethernet (PoE) - 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.

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

• Base consumption + camera streaming: 2.5W - 3W
• PoE circuitry: 0.5W
• AI subsystem consumption: Up to 1W
• Stereo depth pipeline subsystem: Up to 0.5W
• Video Encoder subsystem: Up to 0.5W

So the total power consumption can be up to ~5.5W 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.

We recommend using OAK Y-Adapter with USB-C Female -> USB-C Male extension cable if you are having powering issues.
