Assistance Needed for Standalone Streaming Setup on Multiple OAK PoE Cameras

jakaskerl · Feb 1, 2024

HI @nikul
I tested you script and it works great on Oak-D-Pro Poe. It does not flicker at all. Are you experiencing the flickering in host mode or just in standalone? Does it help removing the color_cam.initialControl.setManualFocus(100) # 0..255?

"0.0.0.0" IP won't work, you have to specify the IP of the device directly. Camera not detected error stems from the fact that OAK-1 poe only has 1 camera (on socket 0). Stereo needs cameras on socket 1 and 2.

Thanks,
Jaka

It flickers only on Standalone. I have applied the same code to the all my four OAK PoE cameras however effect of this code color_cam.initialControl.setManualFocus(100) # 0..255is only appearing on OAK-D-Pro. and none other.

"0.0.0.0" IP won't work, you have to specify the IP of the device directly. Camera not detected error stems from the fact that OAK-1 poe only has 1 camera (on socket 0). Stereo needs cameras on socket 1 and 2.

0.0.0.0 is just for security purpose I am using device IP while running in into my system. I aware of the fact that I need OAK-D or OAK-D-Pro to stream depth view. i do have both of them connected to my network.

Hi @nikul
Which Oak-D-pro Poe is this? This is what /examples/ColorCamera/rgb_preview.py prints out for a camera I tested and which had no issues with flickering:

Connected cameras: [{socket: CAM_A, sensorName: IMX378, width: 4056, height: 3040, orientation: AUTO, supportedTypes: [COLOR], hasAutofocus: 1, hasAutofocusIC: 1, name: color}, {socket: CAM_B, sensorName: OV9282, width: 1280, height: 800, orientation: AUTO, supportedTypes: [MONO], hasAutofocus: 0, hasAutofocusIC: 0, name: left}, {socket: CAM_C, sensorName: OV9282, width: 1280, height: 800, orientation: AUTO, supportedTypes: [MONO], hasAutofocus: 0, hasAutofocusIC: 0, name: right}]
Usb speed: UNKNOWN
Bootloader version: 0.0.26
Device name: OAK-D-PRO-POE  Product name: OAK-D-PRO-POE-AF

I flashed the application you have sent to the device and experienced no issues.

Thanks,
Jaka

@jakaskerl
Hi, Thank you for getting back.
Can I set the focus manually. To the OAK 1.
Here is description of my device.
[{socket: CAM_A, sensorName: IMX378, width: 4056, height: 3040, orientation: AUTO, supportedTypes: [COLOR], hasAutofocus: 0, hasAutofocusIC: 1, name: color}]

Hi @nikul
hasAutofocus is 0 so no.

Thanks,
Jaka

Thank you @jakaskerl
1. I am unable to setManualFocus with this.
# Start defining a pipeline

pipeline = dai.Pipeline()

# Define a source - color camera

cam = pipeline.create(dai.node.ColorCamera)

cam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_1080_P)

cam.initialControl.setManualFocus(2)

[{socket: CAM_A, sensorName: IMX378, width: 4056, height: 3040, orientation: AUTO, supportedTypes: [COLOR], hasAutofocus: 0, hasAutofocusIC: 1, name: color}, {socket: CAM_B, sensorName: OV9282, width: 1280, height: 800, orientation: AUTO, supportedTypes: [MONO], hasAutofocus: 0, hasAutofocusIC: 0, name: left}, {socket: CAM_C, sensorName: OV9282, width: 1280, height: 800, orientation: AUTO, supportedTypes: [MONO], hasAutofocus: 0, hasAutofocusIC: 0, name: right}]

This camera does comes with Auto Focus features.

Hi @nikul
You probably have the FF variant.

Thanks,

Hi @Jackmarks Thank you for getting back.

Couple weeks back when I tried, I was able to set focus. I did not try all the parameters but set focus to 0 and it was all blur.

Thank you

jakaskerl · Feb 6, 2024

Hi @nikul
Are you sure it was the same camera?
Try with https://docs.luxonis.com/projects/api/en/latest/samples/ColorCamera/rgb_camera_control/.

Control:      key[dec/inc]  min..max
  exposure time:     I   O      1..33000 [us]

Turns out the setResolution() also something which not really working for me. whatever perameter I set in my video surveillance system it is showing 1080.

Also I want to crop the streaming and want to get only center of the video, can you show my how can I apply this considering the code I have provided above.

Thank you.

nikul Turns out the setResolution() also something which not really working for me. whatever perameter I set in my video surveillance system it is showing 1080.

Please add a MRE of this issue so we can pinpoint the culprit.

nikul Also I want to crop the streaming and want to get only center of the video, can you show my how can I apply this considering the code I have provided above.

Create a ImgManip node
Link camRgb as input, and pipe the output to whatever you need (streaming/NN/etc)
use Imagemanip's manip.initialConfig.setCropRect() or manip.initialConfig.setCenterCrop()
Keep in mind, values for the second one are normalized (0-1)

Thanks,
Jaka

jakaskerl · Feb 8, 2024

Hi @nikul
I think 720P is not supported on IMX378, that's why it's defaulting to 1080p. Other (higher) resolution should work as intended.
And you should be getting a warning for unsupported resolution in the depthai during bootup.

Thanks,
Jaka

Nnikul · Feb 9, 2024

jakaskerl Thank you.
Is there anyway we can reduce the bitrate in MJPEG streaming.

jakaskerl · Feb 9, 2024

Hi @nikul
setQuality (https://docs.luxonis.com/projects/api/en/latest/references/python/#depthai.node.VideoEncoder.setQuality) should reduce the bitrate afaik.

Thanks,
Jaka
