AR0144 RGB output on VOXL2
-
Here are two image samples taking using IMX412 and AR0144. IMX412 is slightly cropped on the sides, but it's also a slightly narrower lens. AR0144 image is without LSC correction. Also images slightly out of focus because the test pattern is very close to the camera. The brightness in the IMX412 image is more evenly distributed (larger, better lens), so the center of the image is not over-exposed, unlike the AR0144. This should be corrected with the proper LSC..

@Alex-Kushleyev, I just got the color AR0144s and was wondering what changes I need to make to the config file to get the RGB output from the AR0144s. I chose configuration 27, but when I open the stream in the VOXL web portal, I only get monochrome streams from the AR0144.

@Jordyn-Heil , you will need to use a recent version of
voxl-camera-server(you can build it from dev or get a package from the nightly builds).Then edit the camera server config file (
/etc/modalai/voxl-camera-server.conf) and replace the camera typear0144withar0144-color. If you get an error (unknown camera type), it means you are using older version of camera server.Currently, the debayering is happening on the CPU.
Here is the place where processing is happening for the color version of AR0144. https://gitlab.com/voxl-public/voxl-sdk/services/voxl-camera-server/-/blob/dev/src/hal3_camera_mgr.cpp?ref_type=heads#L1477
- debayer from GRBG to RGB
- run AWB (auto white balance)
- run AE (auto exposure)
- send out RGB, grey, and original raw bayer frames
Please try it out.

@Alex-Kushleyev, building from the dev branch worked great, thanks!
On a separate note, for my application, I will need the coax cables connecting the cameras to be slightly longer. Do you all make longer cables, or are you aware of any other suppliers that make longer versions of these cables?
-
@Jordyn-Heil , yes we make cables from 35 to 180mm : https://www.modalai.com/products/mcbl-00084
If you are purchasing new cameras and need a non-standard cable length (I believe standard is 80mm), you may need to contact us by email for a custom order.
