Autoexposure issue with DAVIS346 #105

Closed ahadviger closed 3 years ago

ahadviger commented 4 years ago

Hello,

I was using dvs_renderer to record ROS bags with a DAVIS346 device. Autoexposure was enabled by setting autoexposure_enabled: true in the configuration .yaml file. At first everything seemed to work fine, but then exposure started to oscillate between two values and never recovered. Is there anything that can be done to avoid this?

Thank you, Antea

Just for info, the DAVIS ROS driver uses its own implementation of auto-exposure, distinct from the libcaer one, code here: https://github.com/uzh-rpg/rpg_dvs_ros/blob/master/davis_ros_driver/src/driver.cpp#L857 Looks like both suffer from potential oscillations in edge cases due to relatively simple control loops.
