OAK-D SR

dwffls

Hi there,

Just got my OAK-D SR in the mail today, hardware looks very promising!

Unfortunately I was not able to get the depth sensing to work. I've first tried to run the depthai_demo.py, here the depth tab was unavailable. Then tried to run the Depth Preview tutorial with some changes (pipeline.create(dai.node.MonoCamera) -> pipeline.create(dai.node.ColorCamera) and monoLeft.out.link(depth.left) -> monoLeft.video.link(depth.left), for both cameras). However it still could not output anything.

Finally tried device.getConnectedCameras() and all I got was: [<CameraBoardSocket.RGB: 0>]. So it appears as the second camera can not be reached.

Tried to find extra information on github and the documentations, but to no avail.

Can somebody explain what i'm missing/doing wrong here?

Hi dwffls
Try running the following script:

from depthai_sdk import OakCamera

with OakCamera() as oak:
    cams = oak.create_all_cameras()
    oak.visualize(cams)
    oak.start(blocking=True)

Thanks,
Jaka

Hi Jaka,

Tried running your code, all I got was one window "CameraBoardSocket.RGB" with a live rgb image. This appears to be the right camera, so no image of the left cam.

Also tried the same code on a normal OAK-D S1 and got 3 windows of all 3 cameras.

Could this mean the device is DOA?

Thanks in advance,

Daan

Hi dwffls
Could you try running the same example on the latest "develop" branch (link).
Sorry for the inconvenience.

Thanks,
Jaka

Hi, finally got both images out of the camera with the cpp library. Unfortunatly passing these to the dai::node::StereoDepth does not output a depth image. The queue does not appear to provide us with a new image.

If you want to i could still try the developer branch? But the problem seems not to be with the camera itself.

Hi dwffls ,
Yes, I believe the latest develop has the support for the OAK-D-SR, could you try it out as well?
Thanks, Erik

Hi! I'm just going to jump in here, since I am experiencing the same problem.

Yes, I believe the latest develop has the support for the OAK-D-SR, could you try it out as well?

I have found that I can successfully run the depthai_demo.py program from the depthai repo, main branch (commit 7c9f9897cd0a6d7dacdafc03125bec0ccc6f06ec), but I am unable to select the depth tab. Further, I am only able to select color and nnInput from the drop down box in the GUI (no depth or individual left/right images etc).

However, if I clone and build the examples in the depthai-core repo, develop branch (commit 75b93d617bf97b3fcd57504438592c294ab64478), I am able to run the examples/depth_preview executable and see the depth output. However, when I try to run the rgb_preview or rgb_video executables I get the error:

[1844301041C04B1200] [3.3] [1.267] [ColorCamera(0)] [error] Camera not detected on socket: 0

Is there a repo/branch combination that I should be using? Or is it just that the SR is still "early-access" and we just need to wait for the support to become available?

Cheers, Pete

Hi pete
To my knowledge, the depthai_demo.py script doesn't yet support SR depth but will in the future. The develop branch for depthai-python should have support for SR (meaning it detects both cameras), but to use depth - color camera stereo - you would have to use example scripts/custom made ones and manually specify the cameras used in stereo matching. The demo script does not currently know how to do that.

Thanks,
Jaka
