Circles extraction

[user1254]

Hi,
I've been using the obstcle_detector package for a while now but I still don't know how to fix this problem.

When the lidar is near some walls, i can see on Rviz, trough Obstacle Extractor, some circles even though they shouldn't appear. I tried to modify some parameters on the Obstacle Extractor but still can't get rid of these circles.
Is there a solution for this?
Example here: https://prnt.sc/qy0tut
Of course this is one example but this happens several times while the lidar moves on.
Thank you

Hello,

I am having some trouble. What kind of parameter tuning you have done? Can you list it? Is there any solution for this?

I used this package for dynamic obstacles, like walking humans. This package is unable to provide obstacle circles for walking humans but, when the human slows down for a moment to turn, the package is able to make circles. Can I get a solution to how to detect the dynamic obstacle?
