ZED X One 4k bad quality when HDR is enabled

Hardware ZED1
1

Hi,

We are recording using a few ZED One 4K cameras, and we observe overexposure and bad image quality in situations where we would expect HDR to solve the problems. Here are a few questions

1- We noticed that we can’t activate HDR in the 4K config, then read here Zed X one 4K clear HDR that it’s not supported, are there concrete plans to support HDR for 4K? How about support for 1080p?

2- We see that the 1200p and QHD+ configurations support HDR, however, when activated we see bad image quality, as you can see in these images (grabbed from ZED_Explorer)

1200p with HDR

Do you have any thoughts on what parameters to tune, or other approaches to use to improve the image quality in these cases?

Background:

  • We are using ZEDX One 4K and ZED Box Orin Nano
  • We are tried both with SDK 5.1.1 and SDK 5.2.3
  • The problem is prevalent in a non-trivial amount of data collected with the sensor, in some cases it complete image blow outs when recording with 4K
