Hi,
I want to calibrate IMX462 with OAK-FFC-3P, but depthai repo doesn't support it yet and I get this error message:

[14442C1031B42BD700] [3.3] [4.047] [system] [warning] Calibration Data on device is empty

  File "calib.py", line 550, in create_pipeline
    cam_node.setResolution(camToRgbRes[cam_info['sensorName'].upper()])

Thanks, Andrzej

    Hi AndrzejFijalo

    • make sure you are running the latest depthai
    • run a git pull --recurse-submodules to make sure your repo is up to date
    • (optional) switch to develop branch

    Thanks,
    Jaka

        Hi

        jakaskerl

        Sorry for late response, but i checked your solution and still depthai repo gives me error with sensor detection IMX462 as IMX286 🙁

        Screenshot for confirmation:

        also in main:

        My json config is this:
        {
        "board_config":
        {
        "name": "Custom FFC",
        "revision": "R1M0E1",
        "cameras":{
        "CAM_A": {
        "name": "rgb",
        "hfov": 80,
        "type": "color"
        }
        }
        }
        }

        What can i do to resolve this issue??

        Thanks, Andrzej

            Hi AndrzejFijalo
            Looks like the resolution support was not added for 462. Since it is still recognized as IMX296, try adding this:

            camToRgbRes = {
                'IMX378' : dai.ColorCameraProperties.SensorResolution.THE_4_K,
                'IMX214' : dai.ColorCameraProperties.SensorResolution.THE_4_K,
                'OV9782' : dai.ColorCameraProperties.SensorResolution.THE_800_P,
                'IMX582' : dai.ColorCameraProperties.SensorResolution.THE_12_MP,
                'AR0234' : dai.ColorCameraProperties.SensorResolution.THE_1200_P,
                'IMX296' : dai.ColorCameraProperties.SensorResolution.THE_1080_P,
                }

            Let me know if it works.

            Thanks,
            Jaka

                Hi, jakaskerl
                Unfortunately it doesn't work 🙁

                after i press spacebar calibration.py just hangs up and preview image doesn't show up, so IMX462 is not supported.

                What can I do now?
                Thanks;
                Andrzej

                  HI jakaskerl
                  My apologies, but it was wrong screenshot, here is the correct one:

                  After pressing spacebar calibration.py just hangs up.

                  I've done exactly this steps:

                  1. make virtual environment
                  2. install depthai 
                    git clone https://github.com/luxonis/depthai.git
cd depthai
git submodule update --init --recursive
python3 install_requirements.py
                  3. add json file 
                    {
    "board_config": {
        "name": "Custom FFC",
        "revision": "R1M0E1",
        "cameras": {
            "CAM_A": {
                "name": "rgb",
                "hfov": 80,
                "type": "color"
            }
        }
    }
}
                  4. add line of code 
                    camToRgbRes = {
                'IMX378' : dai.ColorCameraProperties.SensorResolution.THE_4_K,
                'IMX214' : dai.ColorCameraProperties.SensorResolution.THE_4_K,
                'OV9782' : dai.ColorCameraProperties.SensorResolution.THE_800_P,
                'IMX582' : dai.ColorCameraProperties.SensorResolution.THE_12_MP,
                'AR0234' : dai.ColorCameraProperties.SensorResolution.THE_1200_P,
                'IMX296' : dai.ColorCameraProperties.SensorResolution.THE_1080_P,
                }
                    I've check also an develop branch and this same result.

                  What can I do now with calibration?
                  Thanks,
                  Andrzej

                      Hi AndrzejFijalo
                      I just checked with 462, it works as expected on the develop branch:

                      git clone https://github.com/luxonis/depthai.git
cd depthai
git checkout develop
git submodule update --init --recursive
python3 install_requirements.py

                      Running cam_test.py, correctly shows IMX462.

                      This means the calibration should work as well, provided you set the resolution for IMX462 (instead of 296).

                      Thanks,
                      Jaka

                          yes, in depthai-python repo IMX462 is supported in develop branch, so IMX462 is detected. I was looking in Luxonis commit history and this sensor support was merged in this PR luxonis/depthai-python922#issue-2002173555

                          But commit history for depthai repo looks like last commit on develop branch is from 2nd of November

                          But you are sure that this sensor is also supported in depthai repo? I just do exactly what you write on two separate machines and it doesn't work at all. For double check i was trying to run depthai_demo.py and it also don't recognize IMX462.

                          sorry for inconvenience, but i really need this calibration xD

                          Thanks, Andrzej

                              AndrzejFijalo yes, in depthai-python repo IMX462 is supported in develop branch, so IMX462 is detected.

                              It's the same depthai version so it should work whether you are using it on depthai-python or depthai repo.

                              AndrzejFijalo For double check i was trying to run depthai_demo.py and it also don't recognize IMX462.

                              Depthai_demo will force you to run an earlier version of depthai - unless you pass the --skipVersionCheck flag. Did you do that?

                              EDIT: Tested, won't work on 2-LANE mipi, but works fine on 4-lane.

                              Thanks,
                              Jaka

                                  @AndrzejFijalo could you please let me know where you purchased an IMX462 compatible with the FFC module? I can't see any in the Luxonis store.

                                    The IMX462 is currently out of stock on the Luxonis store.

                                    Thanks,
