[tarekmuallim]

OAK-FFC-4P still can not detect the connected camera module for some reason! Using DepthAI or DepthAI Core, the result is the same.

[themarpe]

Sorry for the issue @tarekmuallim.

We'll take a look at this and get back to you ASAP.

[themarpe]

@tarekmuallim IMX283 is not supported by DepthAI ecosystem at the current time.

[tarekmuallim]

Hi @themarpe in this link it has been listed as support!

https://docs.luxonis.com/projects/hardware/en/latest/pages/arducam.html#oak-ffc-camera-modules

[themarpe]

Will have to double check, or we'll need to add support for it. I'll get back to you in a couple of days

[themarpe]

@tarekmuallim Sorry for the issues, I'm not aware as to how this sensor got to the supported list - it is not fully supported by DepthAI.

There is a "PoC" means of running it on depthai-experiments repository on branch: arducam_imx283 the following commands:

cd depthai-experiments/gen2-color-isp-raw # on the branch arducam_imx283
python3 -m pip install -r requirements.txt
python3 main.py

^ for this, preferred is python3.9 or older as prebuilt wheels are already available.

Thanks for the headsup, we'll fix the list. Feel free to reach out to support at luxonis if there is a commercial need for this specific sensor to be mainlined into DepthAI ecosystem.

[tarekmuallim]

@themarpe I can't understand what is going on here.This is not a mistake in a table, it is more.

In the documentation the sensor is listed as supported: https://docs.luxonis.com/projects/hardware/en/latest/pages/arducam.html#oak-ffc-camera-modules

When you press on the IMX283-M12 it will lead you to AdruCAM website: https://www.arducam.com/product/arducam-20mp-imx283-camera-module-with-m12-mount-lens-and-adapter-board-for-depthai/ The title there is : Arducam 20MP IMX283 Camera module with C mount lens and adapter board for DepthAI OAK !!!

When you press on buy now you go to: https://www.uctronics.com/arducam-20mp-imx283-camera-module-with-m12-mount-lens-and-adapter-board-for-depthai.html

Again the title is :Arducam 20MP IMX283 Camera module with C mount lens and adapter board for DepthAI OAK All of this indicates that this is a fully supported camera.

This is bigger than a mistake in a table.

[themarpe]

I am aware of this - as stated, the support is not full unfortunately - the reason for this is likely a legacy move on tech direction of which sensors are best to be supported, and this one stayed in "alpha" stage.

I'm sorry for the trouble - does the interim UVC mode support for this sensor work for you?

[tarekmuallim]

Hi @themarpe We are working on developing an AI based barcode reader. For that we chose this sensor. We have already worked before with OAK-1 for another project “self checkout system” and the product is almost finished and we are happy with the results. For that we chose OAK-FFC-4P. We are using c++ “DepthAI Core” for development and python for some quick tests.

UVC mode is not enough as the deep learning model and the computation should be onboard.

We have contacted ArduCAM and they said that the IMX283 camera module is released only to be used with OAK! But as I understand from you it is not supported and looks like there is no plan to support it!

At the beginning I thought that this was some sort of a bug, for that I reported on github. Do I have to contact support@luxonis.com ?

[themarpe]

@tarekmuallim

The IMX283 sensor is on route to me and I'll mainline it after I receive it. Sorry for the inconvenience

Hello @themarpe I am getting this error, https://github.com/luxonis/depthai-python/issues/743 any solution for this ?

hello @tarekmuallim , i am also using this sensor in my project with Jetson Xavier, could you please take a look at the error and suggest me some solution if you also faced the same issues (https://github.com/luxonis/depthai-python/issues/743), Thank you

[tarekmuallim]

Hello @themarpe Is there any news related to IMX283 sensor?

[cafemoloko]

Hello @tarekmuallim - we are working on the last fixes, but in general, the streaming works. Thank you for your patience.

[alex-luxonis]

@tarekmuallim An initial version is available now, on the imx283 branch, on top of the latest release. After checking out the branch, please run python3 examples/install_requirements.py

Current status: streaming at 5312x3692 (maximum width supported now by the ISP processor is 5312), max FPS is 20. Exposure control is not working properly yet (applied exposure appears to be low at the default 20fps), and a lower FPS would apply a longer exposure. The ISO/gain setting works, however an observation with the Arducam module is that high gains create horizontal pattern artifacts. A workaround for now to get a higher exposure is to reduce the FPS, and/or increase the aperture of the lens, if available.

Needs a 4-lane camera socket on the FFC devices: RGB/CENTER/CAM_A, or CAM_D. 180-rotation doesn't seem to be available with IMX283 (found only a vertical flip setting, and not horizontal mirror). To capture a normal upright image, the Arducam module has to be mounted with the FFC connector upwards.

Can use for a quick test: python3 utilities/cam_test.py -cams rgb,c and options like: -ds 2 to downscale 2 times (to 2656x1846), -fps 10.0 (can be lowered down to 0.074 -- would apply very long exposures currently), -rs to make the OpenCV window resizable (this option is not enabled by default as the OpenCV scaling may create artifacts), pressing C to capture an image.

By the end of the week we should get the exposure issue fixed, and will try to add more sensor resolution settings (cropping to 16:9 ratio approximately 5312x3000 , further cropping to 4K) - these should also work at a higher 30+ FPS.

@themarpe @cafemoloko Thanks for the update.

The exposure and gain issues are fixed on the imx283 branch. A note that for this sensor, if the configured FPS is lower than about 1.18, then the minimum exposure that can be set gets larger. When running with DEPTHAI_DEBUG=1, logs like below would signal that:

IMX283 WARN: requested exposure (100000 us) outside of possible range [54, 49870] for 20.001 fps, capping
IMX283 WARN: requested exposure (100000 us) outside of possible range [148046, 999871] for 1.000 fps, capping
IMX283 WARN: requested exposure (100000 us) outside of possible range [9148037, 9999862] for 0.100 fps, capping

The sensor is configured by default to 5312x3692 resolution, and this should work all good up to 20 FPS. Setting THE_4_K is also possible, however at the moment it doesn't work properly if the FPS configured is higher than about 19 (actual FPS gets lower, and artifacts - black pixels appear on the top and bottom lines).

Hello @alex-luxonis @cafemoloko I have checked out the branch imx283 and update everything needed. But I steel can not detect the camera! Any suggestions?

[alex-luxonis]

Hi @tarekmuallim, after running python3 examples/install_requirements.py, with the camera connected to CAM-A or RGB socket, I get: python3 utilities/cam_test.py -cams rgb,c -rs -ds 2

Enabled cameras:

Could you check the depthai version printed, the hardware connections (can post a picture here).

If things still don't work, it may be that your FFC board isn't properly identified as OAK-FFC-3P or OAK-FFC-4P, if perhaps EEPROM was overwritten with some calibration data. Can try to fix as here: https://github.com/luxonis/depthai-python/issues/788#issuecomment-1473965237 (and for more details on why that's needed: https://github.com/luxonis/depthai-python/issues/788#issuecomment-1470412541)

@tarekmuallim The issue seems to be with depthai version when the cam_test.py script is ran, it uses a release: DepthAI version: 2.21.2.0 (no development commit hash at the end) But install_requirements.py appears to have used the right version from the branch: Requirement already satisfied: depthai==2.21.2.0.dev+334b7d3a471c0ad727d1a70443015d8d21f801d8 in /home/tem/.local/lib/python3.8/site-packages (2.21.2.0.dev0+334b7d3a471c0ad727d1a70443015d8d21f801d8)

But the library paths looked the same, not sure if the library was reinstalled in the meantime, or running in a virtual environment. Anyway, you can try:

python3 -m pip uninstall depthai -y
python3 -m pip install --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/ depthai==2.21.2.0.dev+334b7d3a471c0ad727d1a70443015d8d21f801d8
python3 -c "import depthai as d; print(d.__version__)"         # Should print the same commit hash as above
python3 utilities/cam_test.py -cams rgb,c camd,c -rs -ds 2     # Should print the same commit hash as above
