Zed X One 4K overexposed during daytime direct lighting outdoor conditions

Hardware ZED X
1

Hello, I am reaching out regarding an overexposure issue during the daytime with direct lighting conditions in an outdoor environment.

I am using the Zed X One 4K GMSL camera with the Zed Link Duo capture card on Jetson Orin AGX. I am running Jetpack version 5.1.2-b104 and using the driver version 1.3.0-LI-MAX96712-ALL-L4T35.4.1.

The problem is similar to that described in https://community.stereolabs.com/t/auto-exposure-is-not-working-well-zed-x-one-4k/6060. It was stated that upgrading to the latest driver would fix this issue but it appears I am still facing it.

Currently, to mitigate the overexposure during the daytime from direct sunlight, I am manually adjusting exposure parameters as follows:

g_object_set(src,
                     "exposuretimerange",
                     "100000 1000000",
                     "gainrange",
                     "2 2",
                     "ispdigitalgainrange",
                     "1 1",
                     NULL);

This achieves acceptable exposure during the aforementioned lighting conditions. However, during decreased lighting conditions after sunset results in totally pitch black video quality despite artificial lighting. If I remove the above adjusted parameters for this situation, the stream is no longer completely dark.

I am wondering if there is something erroneous about my configuration setup or versions. I would appreciate any insight and help into this matter. Thank you

Hi @Lrnts
what GStreamer element are you using? The generic nvidia argus camera source or our official zedxonesrc?

Hi @Myzhar, thanks for the reply. I am currently using nvarguscamerasrc, not your zedxonesrc. I will try making the change and will let you know if that fixes the problem. Thanks again for the help
