Could you elaborate a little...?

Hi, I have the same question. Is there a way to adjust the "set auto exposure" setting in launch file or node parameter rather than using rqt_reconfigure?

[doronhi]

You can add the following lines to your launch file before the section of launching realsense2_camera node:

<rosparam>
  /camera/rgb_camera/auto_exposure_roi/left: 30
  /camera/rgb_camera/auto_exposure_roi/right: 350
</rosparam>

(you can check the precise string using rqt_reconfigure)

I have the same question as @wikpunGitHub, but in my case there is no /camera/rgb_camera/auto_exposure_roi visible on rqt_reconfigure, only /camera/stereo_module/auto_exposure_roi exists. I can also see a top and bottom parameter.

Hi @denseishin Which RealSense camera model and ROS1 wrapper version are you using, please?

[denseishin]

I'm using a D405, but to do so I'm using rjwb1's fork #2297

Even though development on the official ROS1 wrapper has ceased, the RealSense ROS development team recently added support for the D405 PID to the wrapper, as described at #2915 (comment)
