Hi everyone,

is there a way to take some raw snapshot from the HiRes camera (IMX412 w microcoax wires)?
I see that the file created by "voxl-send-command hires_large_color snapshot" is pretty small (less then 800KB)
The preview on the voxl portal seems even better compared to the jpg image

thank you in advance!

@Alex-Kushleyev

I set the "ae_mode" to "off" and it works!

thank you

@Alex-Kushleyev

I tried
voxl-send-command hires_small_color set_exp_gain 5.0 200

i receive the message "Successfully sent command to /run/mpa/hires_small_color/control" but I don't see any difference, in the voxl portal it continues to say "exposure: 26.916ms, gain: 800"

Hi,
I'm working with an IMX412 on voxl 2, is there a way to manually set camera parameters like exposure time and gain? in my application I use an onboard light and the drone will always fly indoor in the same conditions, so I prefer to work with fixed parameters instead of letting the auto exposure do its things

Thank you in advance

@Alex-Kushleyev , one more question;

I'm using two AR0144 cameras as a stereo setup. Should I use the "combo driver" to synchronize them?
I remember that about a year ago I had an issue with a different setup where the cameras weren't perfectly synchronized, and the images were captured with a slight time offset.
In this case, how should I set the IDs in the camera server, and what connections should I use to ensure they work correctly?

@Alex-Kushleyev

Hi Alex, it works fine

thank you very much!

Hi everyone,

I'm working with a VOXL2 setup using the microcoax adapter (MDK-M0173-1-00), and I have three AR0144 and IMX412 cameras connected. (same connection used on starling2, without ToF sensor - image attached)

I need to flip the IMX412 camera image upside down, but I haven't found a way to do this via the voxl-camera-server.conf file. In the past, I've managed this using the "imx412-flip" drivers found under /usr/share/modalai/chi-cdk, but the problem is that my IMX412 camera is assigned to ID 1, and there is no driver for that ID

Is there a way to solve this problem?

Thanks in advance for any help

@Alex-Kushleyev

I tried with only one M0036 extension cable and it works, but as I connect the second pair of cameras with one more M0036 extension it starts to have some issues, the camera server sometimes starts but most of the times it doesn't, if it does I get a mixed preview of the cameras in the voxl portal, for example I want to see a preview of one pair of stereo and instead of seeing left and right cameras I see one of the front and one of the rear, and then it crashes,
I already tried to replace the extensions, the cameras and even the voxl with brand new pieces but that configuration doesn't work, the only way is to use the shorter extension cables M0074 on one of the stereo pair (or both), with that extension I never got any type of problem.
I am using the SDK 1.3.0
The camera preset I am using is the 11 (sentinel)
The camera server detects all the cameras, if I disable one of the two stereo pairs it seem to work

Hi @Alex-Kushleyev ,
I use a configuration like the photo below, I still need to test the IMX412 hi-res with a custom extension cable,
do you think it would be better to lower the bitrate also for that camera?

@Vinny
I am using the Sentinel configuration:
stereo front - Omnivision OV7251
stereo rear - Omnivision OV7251
tracking - Omnivision OV7251
hi-res - Sony IMX214 (eventually I will use the IMX412, but I still need to try it)
