Davis 346 exposure issue

[Lydia Schwarz]

Hi,

I'm using Davis 346 to test a slam project, so i follow the instructions to use kalibr toolbox for calibrating. When i run davis_ros_driver and start to record a rosbag i find that the image output is too dark for calibrating.

In DV software, the APS output is as below. I guess the problem is the exposure parameter setting in the ROS driver, but i don't know where to modify. Can anyone help me?

The RPG ROS driver and DV use different auto-exposure methods.

If you need ROS, I'd recommend using our ROS driver:

You can control exposure in:

dv_ros_capture/config/dynamic.yaml

and change auto_exposure and exposure to the wanted values.
