Hi, one of my three OAK-D Pro PoE cameras is not applying `initialControl.setManualFocus(lens_position)`. I noticed this by setting the lens position of the first cam to 0 which leads to a blurry image as expected. At the same time, I also set the lens position of cam 3 to 0 as well which did not change the blurriness at all. As reference, cam 2 in the middle is set to lens position 119 leading to the desired outcome: [URL=https://i.imgur.com/SqJ6VWN.jpg][IMG]https://i.imgur.com/SqJ6VWNh.jpg[/IMG][/URL] Cam 1 and 2 behave perfectly fine, only cam 3 seems to ignore `setManualFocus` . This was also observed using the `rgb`*`camera`*`control` [script](https://docs.luxonis.com/projects/api/en/latest/samples/ColorCamera/rgb_camera_control/#rgb-camera-control), which does not use `initialControl` but rather the `camRgb.inputControl` at runtime. I also tested exposure, ISO and auto-focus using this script which all seem to work fine on cam 3. Although auto-focus functionality is hard to tell because the preset lens position cam 3 seems to be stuck on is quite close to optimal. Opening up the Device Manager, cam 3 seems to be using the latest firmware/bootloader version: [URL=https://i.imgur.com/tpZVV02.png][IMG]https://i.imgur.com/tpZVV02.png[/IMG][/URL] Once again, any help or hints are greatly appreciated!

OAK-D Pro PoE camera not applying lens position

Hi aschlieb
Are you sure the third camera is AF? There are both AF and FF variants available and there could be a mixup.

import depthai as dai
with dai.Device() as device:
    print(device.getConnectedCameraFeatures())

hasAutofocus should be 1.

Thanks,
Jaka

Hi,

yes, it is the autofocus version:

[
   {
      "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"
   }
]

This is the code I used:

device_info = dai.DeviceInfo("<mx_id redacted>")
with dai.Device(pipeline, device_info) as device:
    mx_id = device.getDeviceInfo().getMxId()
    print("Connected to:", mx_id)
    print(device.getConnectedCameraFeatures())

Would it help you if I messaged you the MX-ID of the camera in question?

Thanks!

While checking all three cameras for the autofocus feature, I noticed that cam 3 does not autofocus (no lens movement) when starting the rgbcameracontrol script.

Perhaps the lens is stuck?

aschlieb

Do you have any suggestions to how to make it unstuck? I guess physical intervention is needed, like gently bumping the device against a table or something?

That'd be my method yes 🙂
Make sure the camera is actually AF though.

After disconnecting the camera from PoE power and bumping the device slightly, the lens became unstuck and I can now focus manually again. I'm not entirely sure whether the reboot or the bumping fixed it though.
